Scottish GM ban, Earth's magnetic field, OCD, Birth of a new galaxy
As Scotland announces it ban on GM crops and with the current post of chief scientific adviser for Scotland vacant, Adam talks to the previous post holder, Professor Muffy Calder about the role of science advice to government and her reaction to news of the ban. The Earth's magnetic field is weakening which could be a sign that the magnetic poles are soon due to flip. Daniel Lathrop and team at Maryland University are trying to model the Earth's magnetic field using a large molten globe of sodium. Should we be worried if a flip is on the cards? Royal Society Winton book prize short-list: Science writer, David Adam, author of 'The Man Who Couldn't Stop' talks to Marnie Chesterton about his experience of Obsessive Compulsive Disorder. Adam hears about the birth of a new galaxy seen for the very first time. He talks to Chris Martin from Caltech about his latest galactic research published in Nature.
Pluto's surface, Increased Arctic ice in 2013, Linking brains together, Signals of fertility
The New Horizons probe is now millions of miles past Pluto, journeying throgh the Kuiper Belt, but still sending back gigabytes of data coming in via the Deep Space Network. Its latest image of Pluto's surface was released by NASA on Wednesday, of huge mountains emerging from an otherwise flat plain, Dr John Spencer one of the lead scientists on New Horizons, a planetary geologist, discusses what's to be read into the surface images captured over the last weekA new paper just published in Nature Geoscience shows that in 2013, which was a slightly cooler summer than average, arctic ice had grown, by 41% on the previous year. The study, uses data from ESA's Cryosat 2, which incorporates not just the surface area of ice, but the all-important number - the volume Adam examines the results with Rachel Tilling from University College London.Computing has taken a Sci fI step forward this month. Professor Miguel Nicollelis of Duke University, a specialist in brain machine interface experiments, has linked together the brains of four individual rats in order to use the computational power of their brains to carry out tasks including image processing, data retrieval, and even weather predictions. But could this have a therapeutic use in brain damage? Professor Andrew Jackson from Newcastle University, an expert in called 'neural prosthetics' examines the potential.Across the animal kingdom, signals advertising when females are at their most fertile can be pretty striking. Humans are more subtle, though plenty of studies have shown that female behaviour and physiology does change during the menstrual cycle. A new study by Dr Robert Burriss from Northumbria University suggests that faces may be advertising a woman's most fertile time of the month. But are the traits too subtle for most people to notice?Producer Adrian Washbourne.
Pluto: New Horizons
It's billed as the last great encounter in planetary exploration. For the past nine years the New Horizons spacecraft has travelled 5bn km (3bn miles) to get to Pluto On July 14th it performed its historic fly-by encounter with the dwarf planet.Adam Rutherford examines the first images from the New Horizon's probe and hears the first interpretations from mission leaders and scientists at the NASA New Horizon's space centre as the data arrives back to earth. Expect new light to be shed on the Solar System's underworld as first impression s reveal Pluto to be a champagne coloured body with 11000 ft ice mountains and surprisingly smooth surfaces that suggests recent geological activityFor people who grew up with the idea that there were "nine planets", this is the moment they get to complete the set. Robotic probes have been to all the others, even the distant Uranus and Neptune. Pluto is the last of the "classical nine" to receive a visit. Dame Jocelyn Bell Burnell discusses how this 2,300km-wide ice-covered rock was demoted in 2006 to the status of mere "dwarf planet", but as "Pluto killer" Mike Brown argues, this shouldn't dull our enthusiasm.As Adam Rutherford reveals, nothing about this corner of the solar system has been straightforward. Little is known about Pluto's creation -but as the New Horizons probe passed Pluto for this first close up of the dwarf planet , scientists anticipate new insights into the evolution of our solar system and even earth's early history.With contributions from mission scientists Alan Stern, Fran Bagenell, Joel Parker and astronomer Mark Showalter. Updates too as interpretations rapidly develop, from BBC correspondent Jonathan Amos and astrophysicist Chris Lintott.Producer Adrian Washbourne.
Intrusive memories, Silent aircraft, Nuclear fusion, Pluto
Adam Rutherford talks to Emily Holmes from the Medical Research Council’s Cognition and Brain Sciences Unit in Cambridge, about two new studies on preventing intrusive memories. She discusses why stopping someone from sleeping after seeing a lab based film of traumatic events like a news reel or car crash may actually stop people from forming intrusive memories about those films. This offers an intriguing insight in to the role that sleep has in consolidating intrusive and possibly traumatic memories. She also explains how if memories of a traumatic event are laid down, why playing a computer game like Tetris could disrupt that memory and stop it from becoming intrusive. Silent Aircraft: The Davies report recently recommended a new, third runway should be built at Heathrow airport but as flight numbers increase how quiet can planes of the future become? Adam talks to Jeremy Astley from Southampton University and Michael Carley from Bath University about where the noise in jet engines comes from, how engineering can make them quieter and will the silent aircraft initiative ever make a truly silent aircraft.Nuclear Fusion. For decades scientists have tried to harness the power of the Sun to smash atomic nuclei together to create a clean, limitless energy source from nuclear fusion. Marnie Chesterton talks to scientists from Tokomak energy about their new design for a Tokomak machine that has already exceeded previous records. Could it be a vital step forward in the quest for nuclear fusion on Earth?New Horizons: On 14th July 2015 the spaceship, New Horizons will complete its 10 year mission to flyby Pluto. BBC Science correspondent Jonathan Amos gives Adam a preview and tells him why he's so excited about the mission and what they hope to discover about the darker regions of our Solar System.
Aphid-repelling wheat, National Institute for Bioscience, Global map of smell, Parrot mimics
Rothamsted Research in Hertfordshire has just finished trials of a new way to repel aphids from wheat. It's a clever system, that takes a gene for a pheromone, called E beta farnesene, from peppermint, and inserts it into wheat. Aphids let off E Beta Farnesene when they are under attack or when a dead bug is detected, and idea was to have the wheat produce the chemical alarm itself. In the lab, the plants had driven aphids away in their droves. But in the field, where controlled lab conditions are not present, there was no measurable reduction. So what's gone wrong? Adam speaks to spoke to plant geneticist to Dr Gia Aradottir who worked on the Rothamsted trial and Professor Mike Bevan of the John Innes Institute.Top biologists have recently met to launch the National Institutes for Bioscience, the N.I.B, a star-studded partnership of eight great British biological Institutes, such as the Roslin- former home of Dolly the Sheep - and the world's longest running agricultural research station Rothamsted Research. George Freeman MP, Britain's first Minister for Life Sciences, provided a bit of glamour to mark the occasion. Tracey Logan was there to meet the key scientists and to ask the Minister about the ambition and role of the N.I.B.A team of scientists has just revealed how they've used genetics to scan the peoples of the world - and amazingly of extinct people from prehistory - to see who can smell what. They've used one particular olfactory receptor, called OR7D4, to build up a global map of what people can smell. Adam Rutherford speaks to Professor Matthew Cobb, from Manchester University to discuss how the different peoples of the world - including long extinct humans - smell different things. Why are parrots such good copycats? A team in Duke University in the US thinks that they have uncovered the exact spot in the brain that gives the parrot this ability. Professor Erich Jarvis studies the genes involved in the structure of bird-brains, and discusses some ideas about how those neurons have developed through a combination of behaviour and genetics.
Malaria drug, Listener feedback, Imaging the singing voice, Classifying human species
Malaria is the single greatest cause of death that humankind has ever experienced, and continues to be a colossal burden on the health of people all over the world. We've had various treatments over the years, but all of them have been weakened when Plasmodium - the parasite that causes the disease - evolves resistance. So the hunt is perpetually on for novel antimalarial drugs. This month, a new one is published in the journal Nature. Adam Rutherford talks to Professor Ian Gilbert from the Drug Discovery Unit at Dundee University to discuss with him how the new compound attacks the plasmodium parasite to prove effective. Radio 3 is currently in the midst of a season focusing on all aspects of the Classical Voice. Science is playing a growing insightful role in understanding how to get the best out of the singing voice. Many singers base their careers on a particular quality of voice, and that sometimes can sound as though we're imposing a lot of strain on our vocal cords. We hear from Julian McGlashan, an Ear Nose and Throat specialist at Nottingham University Hospitals who has taken singers and placed a video endoscope down each of their throats to observe how their vocal tracts behave differently according to the style they sing. And David Howard head of the Audio Lab at York University, discusses how new technology is helping us understand how it's possible for a singer's voice to cut above the sound of an orchestra and still be heard at the back of a vast auditorium.Species might seem like an obvious way to classify organisms, and one way we define species is by reproductive isolation - If you can't breed with it, it's another species. If we successfully bred with Neanderthals, and produced fertile offspring, surely that means that they must be the same species as us? Adam talks to Professor of evolutionary genetics from UCL Mark Thomas to navigate through the messy world of human species.Producer Adrian Washbourne.
Stars, Fracking, Ice Cores, Drunken Chimps
The ALMA telescope array in the Atacama Desert is one of the most sensitive earth based telescopes. It has now captured images of the very first galaxies. Adam talks to Dr Mark Swinbank of Durham University who's part of the team who've unleashed data this week from that universal hinterland that's set to fill in the missing gaps in our understanding of the evolution of the universe.The European Parliament voted this week to place a moratorium on new licences for member states to frack for shale gas until proven safe for the environment. But how dangerous is fracking? A set of articles out this week in the journal Seismological Research Letters attempts to address and dispel some of the myths and misconceptions about fracking, and to get to the root of the very real, increasing frequency of seismic activity. US Geologist Justin Rubinstein and University of Strathclyde geologist Zoe Shipton discuss the evidenceAs global temperatures increase Ice Core scientists searching for clues to Earth's past climatic history face a ticking clock to gather enough core samples before they melt. Only a tiny amount of mountain glacial ice has ever been collected and studied, and in 2016 ice cores from the Alps will be moved to safer storage in Nature's freezer - a giant vault in Antarctica. Marnie Chesterton meets Ice Core researchers from British Antarctic Survey to find out why they need this archive.A new paper shows the first recorded instances of alcohol drinking in wild chimpanzees. Tanya Humle from the University of Kent describes the novel behaviour. With anthropologist Professor Catherine Hill, Dr Humle discusses whether "wild" chimp research is even possible in an age when human and chimp habitats overlap.Producer Adrian Washbourne.
Origins of life, Earthquakes in London, Frog plague, Ancient pollen
Think of earthquake cities and places like San Francisco or Los Angeles spring to mind. But London is also seismically active. 200 years ago, there was an earthquake under Trafalgar Square. Dr Richard Ghail from Imperial College London meets Adam Rutherford on the banks of the Thames to discuss the fault lines under their feet and what engineering challenges this poses.In the beginning, there were chemicals. A geological blink of the eye later, there was LUCA, the last universal common ancestor; a complex cell. How the chemistry became biology is one of the biggest mysteries in science. New studies from University of North Carolina researchers chips away at this unknown, offering evidence on how the genetic code developed in two stages. Adam meets Dr Matt Powner, a chemist at University College London studying the origins of life, to find out how researchers try to answer this fundamental question. How do we know what our landscape used to landscape? Pollen, from buried mud layers, offers a picture of sorts. By gathering tiny pollen grains, and identifying the plant species at different ages, Dr Ralph Fyfe from Plymouth University builds up a picture of European landscapes thousands of years ago. Peak deforestation happened several thousand years ago, as our pyromaniacal ancestors started forest fires to clear land for agriculture. Roland Pease reports.A plague is killing thousands of common frogs in ponds across the UK. Ranavirus causes ulcers on the skin and haemorrhaging. A team at Exeter University has noticed that ponds with fish are more likely to have an outbreak of this virus. Amber Griffiths urges Radio 4 listeners to leave their ponds to the wildlife, and keep frogs and goldfish apart.
Self-adapting robots, Artificial intelligence in medicine, Ageing healthily
We're becoming more reliant on robots to assist in hostile zones from extinguishing forest fires to bomb disposal to decontaminating nuclear facilities. But whereas humans can quickly adapt to injuries, current robots cannot 'think outside the box' to find a new behaviour when they get damaged. Tracey Logan speaks to computer scientist Jeff Clune who's developed a new way to allow robots to adapt to damage in less than two minutes. It will enable more robust, effective, autonomous robots, and may shed light on the principles that animals use to adapt to injury.
El Nino, Echolocation, Seasons, Snakes
El Nino is a weather event that happens every 5 years. It leaves Europe largely unscathed but causes havoc around the southern hemisphere. El Nino causes droughts, floods and has even been linked to an increased incidence of war. And yet it is surprisingly hard to predict. Adam speaks to Professor Adam Scaife, from the Met Office, about unpicking the science from weather chaos.Echolocation is the ability to sense objects using reflected sound. A handful of animal species do this - most bats, some whales and even a few humans. Some blind people use echolocation to navigate the world they can't see. Some make a clicking sound as they walk. Others use the sound of their footfall. In fact, all humans, sighted and unsighted, do it. Adam meets BBC's Damon Rose, who is blind, and they compare skills.Marnie Chesterton travels to Southampton University's Institute of Sound and Vibration Research to meet Daniel Rowan. His team have recently isolated some of the factors necessary to echolocate. The work involved an anechoic chamber - the quietest place on earth and the sound equivalent of nothing.Last week Adam gave the incorrect reason for why we have seasons. Dr Laura Rogers, a physics teacher, puts him right.Dr Rhys Jones, star of BBC TV's Wildlife Patrol talks to Adam about the origin of snakes. A recent paper from a team in Yale hypothesises a common ancestor with tiny hind legs and nocturnal habits. Adam questions why 3400 species of snake have evolved to not have legs, when millions of other animals find them so useful.
Seasonal Variation in Immunity, Chemosynthesis, Role of the ISS, Storing Digital Data in DNA
Many diseases strike harder and more often in the winter, including major inflammatory conditions such as Type 1 diabetes, multiple sclerosis and rheumatoid arthritis. New research out this week has uncovered the reasons why: it turns out that our immune responses are heavily influenced by the seasons. Professor John Todd who led this new global study discusses the results and how this could influence the way we administer medicines in future.Organisms generate energy in all sorts of ways and it can happen in all sorts of weird places, such as deep sea hydrothermal vents, where bacteria takes nasty stuff such as Hydrogen Sulphide, and turn it into useful stuff such as amino acids. This is called chemosynthesis. But it turns out that it doesn't just happen in dark corners of the ocean. As tubeworm expert Nick Higgs explains we are learning that chemosynthesis is everywhere.Major Tim Peake begins his six-month mission to the International Space Station in November,. Ever since its inception, the question of 'what the ISS is for?' has been asked.. So, what sort of science does it deliver? Richard Hollingham reports from Alabama, in a secret NASA research bunker.Two years ago, a team led by Nick Goldman at the European Bioinformatics Institute in Cambridge successfully took a collection of important cultural artefacts, encoded them digitally, and then wrote them in DNA. These included Martin Luther King's "I have a dream" speech, and all the Shakespearean sonnets. He's now collaborated with artist Charlotte Jarvis to encode a new musical composition which will also form a new art installation Music of the Spheres. DNA's ability to store complex digital data appears close to a reality. Could it hold the key to permanent long term storage for anything? Producer Adrian Washbourne.
Listeners' Science Questions
Adam Rutherford investigates the news in science and science in the news.
Nepalese Earthquake, Monkey Hands, Maritime Light Pollution, Light in Bacteria
Nepalese Earthquake The earthquake that struck central Nepal last weekend measured 7.8 in magnitude and has affected up to 1.4 million people. Inside Science reporter Roland Pease joins Adam to discuss the topography of Nepal, and its vulnerability to earthquakes. We hear from Roger Bilham, a seismologist at University of Colorado, and Alex Densmore from Earthquakes without Frontiers on seismic activity in the Himalayas and the difficulty in measuring the scale of the disaster.Monkey Nuts Capuchin monkeys use stone tools to crack open nuts they want to eat. New research by Madhur Mangalam and Dorothy Fragaszy has shown that they moderate the force they use to open these nuts based on whether the nut shows any cracks from previous strikes. This motor skill demonstrates their dexterity as they are picking the optimal way to complete their task. Scientists hope these findings could help to explain the differences in cognitive processes between non-human primates and hominids who learnt to shape stone tools.Maritime light pollution Around a fifth of the world's coasts are illuminated at night by lights and as LEDs grow in popularity we can expect to see these areas get brighter. But until recently the effects of this light on the marine ecology was a relatively unknown and understudied phenomenon. Adam talks to Thomas Davies whose research published this week has highlighted how light is affecting marine organisms; attracting organisms like keel worms whilst repelling others.Wellcome Collection & Bacteria Light Artists, microbiologists, doctors and geneticists will gather at the Wellcome Collection in London this weekend for the Bacteria Light Lab, an event exploring how light is providing the tools for discovering more about bacteria and infections, part of the 'On Light' weekend at Wellcome Collection. Inside Science went along to meet artist Anna Dumitriu and Dr Nicola Fawcett and view- what appear at first glance - somewhat esoteric looking pieces of art which are actually shedding light on the hidden kingdom of microbiology.Producer: Adrian Washbourne.
Healthy Guts; Future High Speed Trading; Body Clocks and Colour; William Smith's Geology Map
The Yanomami people are Amerindians thought to have been completely isolated since their ancestors arrived in South America after the last ice-age. Now a multinational team of scientists has more than made contact with them - it's persuaded them to donate samples of their faeces hoping to find good bacteria and useful genes that people living Western lifestyles are thought to have lost. Maria-Gloria Dominguez-Bello, a microbiologist at the New York University School of Medicine, explains how this could provide valuable insight into causes and treatment of escalating metabolic and inflammatory diseases in the western world.With news this week of a British financier's arrest over alleged involvement in the Flash Crash of 2010, what are the pros and cons of the next new era of superfast computer-led trading? It's now set to happen even faster thanks to a higher speed, transatlantic communications cable that goes live this summer. Tracey Logan discusses new technological developments that get close to trading at the speed of light with science writer Mark Buchanan and hedge fund scientist Matthew Killeya.It's thought that light and dark are the main factors influencing our body clock, but in new research published this week the blue colour of twilight could be the major factor that keeps our clocks entrained to the 24 hour world around us. Tim Brown of Manchester University discusses why it's quality rather than quantity of light that's important.And there's a visit to the Geological Society in London to mark the 200th anniversary of the first geological map of England, Wales and Southern Scotland. It was compiled by the humble canal surveyor William Smith - but as geological historians Tom Sharp and Hugh Torrens reveal, Smith's ingenuity was to revolutionise mineral prospecting and help shape the scientific and economic development of Britain in the midst of industrialisation.Producer Adrian Washbourne.
Hubble Space Telescope at 25
On 25th April 1990, the Hubble Space Telescope (HST) was released into space from the Discovery space shuttle. Though off to a famously bumpy start - the first images sent by Hubble were blurry due to a flaw with one of the mirrors - it has been collecting data that has been contributing towards shaping our understanding of the cosmos and it continues to do so.The HST is operated by the Space Telescope Science Institute located at Johns Hopkins University in Baltimore, Maryland. Tracey Logan speaks to Mario Livio, an astrophysicist at the institute, who shares his perspective on the Hubble mission for the last 25 years and talks about ongoing Hubble projects.At the cutting edge of cosmology research, data recorded by Hubble is used to improve our understanding of such things as the universe's rate of expansion and theories about the hitherto elusive dark matter. A team led by University of Arizona astronomer Peter Milne has found hints that cast a new light on the currently accepted view that the universe is expanding at an increasingly faster rate. Could it be that a particular type of supernova - type 1A - is not the perfect cosmological "Standard Candle" we've thus far thought it to be?Another group of astronomers, led by Dr Richard Massey at the University of Durham, used data from Hubble in their attempt to unravel the elusive nature of dark matter. Dr Massey talks to Tracey Logan about how having a particular angle on a collision between galaxies some 1.4 billion light years away has allowed for potentially the first ever observation of dark matter colliding with itself. We still don't know what the nature of dark matter is, but this could be our first knowledge of it interacting with anything, possibly implying "Dark Forces" at work. This new research is put into perspective by Dr Malcom Fairbairn, who has revived the neglected telescope on the roof of King's College London. He talks to Tracey Logan about how these recent findings could herald genuinely new areas of physics.Meanwhile, closer to earth rocks, what could or should be done about the danger of asteroid impact? This week in Frascati, Italy, the European Space Agency hosts the 2015 Planetary Defence Conference. Detlef Koschny, head of ESA's Near Earth Object section, speaks to Tracey Logan about coordinating global efforts.Producer: Marnie Chesterton.
Legacy of Messenger, Computer Touch, AI and Traumatic Forgetting, Stained Glass Restoration
This month sees the end of NASA's MESSENGER mission to Mercury. It's been the first mission to the sun's closest planet since Mariner 10 flew by in the mid-1970s. Lucie Green speaks to geologist Professor Pete Schultz of Brown University about the orbiter's 4 year surveillance and how new observations of this under explored world are shedding light on the planet's mysterious dark cratered surface.Virtual experiences are coming closer and closer to reality as both sound and vision, and even smell, become convincing. But without the sense of touch you'll never have the full experience. A team at Bristol University has now managed to generate the feeling of pressure projected directly onto your bare, empty hands. Its system enables you to feel invisible interfaces, textures and virtual objects through the use of ultrasound. Roland Pease gets a hands on experience.One of the biggest challenges in artificial intelligence is conquering a computer's so-called "catastrophic forgetting": as soon as a new skill is learned others get crowded out, which makes artificial computer brains one trick ponies. Jeff Clune of Wyoming University directs the Evolving Artificial Intelligence Lab and has tested the idea that computer brains could evolve to work in the same way as human brains - in a modular fashion. He shows how by doing so, it's possible to learn more and forget less.And there's a visit to the Ion Beam Centre at University of Surrey where, in conjunction with a project to restore the Rosslyn chapel near Edinburgh, scientists have provided a new development in stained glass conservation - scrutinising the glass contents at the subatomic level using a narrow beam of accelerated charged particles, to literally decode the exquisite features lost to the naked eye. Lucie Green caught up with the Centre's director, Roger Webb.Producer Adrian Washbourne.
Invasive Species, Coral Seaview Survey, Evolution of the Brain, A New Virtual Reality
Invasive alien species from the cursed Signal Crayfish to the scourge of gardeners, the Japanese Knotweed, are considered some of the biggest threats to biodiversity. This year the EU has launched new legislation that attempts to limit their spread. But how big a threat are they to ecosystems? Science writer Fred Pearce author of The New Wild argues that ecologists are committed to protecting pristine environments from alien invaders, when we should be embracing the changing ecology that invasive species enable. Adam Rutherford discusses the conflicting approaches to invasive species with Fred Pearce and Dr Helen Roy - a scientist at the Centre for Ecology and Hydrology.Corals make up only 0.1% of the ocean floors, but account for up to a quarter of all marine life. A new exhibition at The Natural History Museum is showcasing some of the work of the Catlin Seaview Survey, which is compiling a huge pictorial health check of various reefs to act as a snapshot against which all future reef changes can be compared. We hear from Dr Ken Johnson, the Museum's main coral researcher, and Professor Ove Hoegh-Guldberg, - Chief Scientist for the Catlin Seaview Survey.There's a big gap in understanding the evolution of our brains. But experts, from geologists to computer scientists by way of marine biologists have recently been meeting at the Royal Society, for a symposium entitled 'Origin and Evolution of the Nervous System' to assess what evidence there is. Roland Pease reports.And we explore a new advance in virtual reality. Anil Seth, professor of Consciousness Studies at the Sackler Centre at Sussex University has been experimenting with our sense of self, and our experience of the world, by using a hi tech headset combined with 360 degree cameras to transport your whole experience to a different space. Virtual reality becomes "substitutional" reality'.Producer Adrian Washbourne.
Genetic Map of the British Isles, Drones for Conservation, Lab Photosynthesis, Solar Eclipse
The Romans, Vikings and Normans ruled Britain for many years, but few left their genetic calling cards behind in the DNA of today's mainland Caucasian population. That's one of the insights from the most comprehensive analysis yet of the genetic make-up of the UK's white British population. As the study's lead author Peter Donnelly explains it's produced some big surprises, not least how in contrast, the Anglo Saxons invasion was to account for up to 40% of the genetic mix in much of southern Britain. Much of Britain's current historical information is from a relatively small subset of people, but a genetic study like this sheds light on the history of the masses.The Royal Botanical Gardens Kew is currently at the forefront of trialling drone technology to map and locate remote vegetation The aim is to examine plant health and deforestation in detail, particularly in inaccessible areas around the globe. The team led by Justin Moat and Oliver Whaley have recently returned from Peru, where they've examined the fragile ecosystem threatened by mining in the Lomas region. BBC Inside Science's Sue Nelson was deployed to join the Kew team for a Drone test run.As our energy needs become greater, the impetus to tap the sun's energy directly becomes ever more urgent. A new paper published this month has cracked one of the barriers to efficient conversion of water into oxygen and hydrogen, which plants of course do naturally. Adam Rutherford speaks to Nathan Lewis at California's Institute of Technology who has developed an electrically conductive film that could enable devises to harness sunlight to split water into hydrogen. Chemist Andrea Sella assesses how close we are to achieving artificial photosynthesis and solar fuels.And ahead of tomorrow's solar eclipse, Adam speaks to solar scientist Dr Huw Morgan from the University of Aberystwyth, who together with his colleagues in Svalbard is going to use those precious seconds to answer one of the great enduring mysteries of the sun: why is the corona, the fiery crown around the orb, is a great deal hotter than the sun itself?Producer Adrian Washbourne.
Large Hadron Collider Run Two, Flooding, Nasa's Biggest Rocket, Violin Evolution
Today CERN announced that on 23rd March the largest single machine the world has ever seen gets plugged in, switched on, and rebooted after a 2 year rest. The Large Hadron Collider was crashing particles at energies just off the speed of light, and in doing so, simulating the universe in its neonatal form. It will be shortly achieving energies twice as great as before and as Adam Rutherford hears from particle physicists Tara Shears and Malcolm Fairbairn, vast new opportunities for discovery will open upIn The Archers, the current devastation caused by the rising of the River Am is a stark reminder of the impact of last year's floods and the unpredictable nature of river channels. But a new study argues that if we're to get a better grip on the hazard posed by a river - and even predict the likelihood it will flood - an overlooked factor needs to be embraced. Louise Slater from Queen Mary University of London discusses the missing piece in the puzzleNASA's Space Launch System, or SLS, will be capable of taking astronauts beyond low Earth orbit for the first time since the end of the Apollo era in 1972.Its first - unmanned - launch is due in 2018 and yesterday the first ground test on two of the massive boosters was successfully completed . BBC Future Space Correspondent, Richard Hollingham, reports from NASA's assembly facility to get the measure of this interstellar behemoth.The golden age of violin making was dominated by master violinmaking families from the 17th and 18th centuries but what accounts for their revered acoustic power? Adam speaks to violin virtuoso Tasmin Little and hears of a new study by acoustician Nicholas Makris from Massachusetts Institute of Technology, who's scanned, measured and documented the violin's changing dimensions to try and account for the unique fullness of sound during this era.Producer Adrian Washbourne.
Encoding memories; 350 years of the science journal; Women in science; Ceres
How does the brain lay down memory? For decades the limits of microscopes have meant that a detailed look at the way brain cells encode particular learned skills and events has proved elusive. But in a report published this week a team of researchers has identified how changes in specific connections encode a particular behavioural response. Adam Rutherford talks to Tony Zador of Cold Spring Harbour laboratories who's become the first to crack a piece of the neural code for learning and memory which could have profound medical insights.350 years ago this week, the world's first scientific journal was published. Philosophical Transactions began by drawing together various letters and reviews that cemented the origin of modern science by publishing Isaac Newton, Christopher Wren and other founding members of the esteemed Royal Society. Historian Dr Aileen Fyfe discusses the key moments in the journal's evolution and its legacy today.There's a look at the ongoing representation of women in science following on from a recent report examining the Royal Society's 2014 university research fellows of which only 2 out of 43 were women. The Society's President Sir Paul Nurse discusses how the imbalance in this and in science more generally should be addressed.NASA's Dawn spacecraft is about to arrive in the orbit around the dwarf planet Ceres and will be the first mission ever to successfully visit a dwarf planet. As the spacecraft spirals closer, images have shown numerous craters and mysterious bright spots that scientists believe could reveal how Ceres formed and offer new clues to the origins of our solar system. Adam talks to the mission's deputy scientist Carol Raymond on the latest interpretations of what's currently being observed.Producer: Adrian Washbourne.
Artificial Intelligence, Desalination, History of Forensics, Music from Cells
A computer system has taught itself how to play dozens of video games. AI researchers claim this is a significant step toward machine intelligence, because the learning process is similar to how humans learn. The program, labelled DQN by its creators at Google DeepMind, performed as well as or better than humans at assorted Atari video games, such as Breakout, and Pong. This style of "Deep learning" is useful because it can be more readily applied to real world scenarios. As Adam Rutherford discovers,it's a short step from mastering a driving simulation game to self-driving cars.Desalination to produce fresh drinking water is on the rise, but the bi-products of the process - acidic brine and carbon dioxide, are a growing environmental problem Adam Rutherford talks to Dr Philip Davies who's devised a new idea for treating brine from desalination plants that could help curb carbon dioxide emissions and go a long way towards addressing acidification of our oceans.Plymouth music festival, Biomusic, features a new work by composer Eduardo Miranda, inspired by a fungus mould. Roland Pease meets the musical pioneer who finds music in biological tissuesA new exhibition at the Wellcome Foundation explores the history, science and art of forensic medicine, from the crime scene to the courtroom. Adam heads down to 'Forensics: the anatomy of crime' for a tour with forensic scientist Dr Angela Gallop, who worked on high profile cases including the murders of both Damilola Taylor and Stephen Lawrence, and also meets exhibition curator Lucy Shanahan.
Alzheimer's Disease, False Memory, Diamond Light Source, Twins in Space
Alzheimer's disease is becoming increasingly common as the global population ages. It is estimated that currently 44 million victims of Alzheimer's dementia exist in the world and that this will grow to more than 100 million cases by 2050. The announcement this week of the creation of the Drug Discovery Alliance - a network of labs to fast track dementia treatment aims to address the urgent need to identify drugs that prevent, slow the progression, or improve the symptoms of Alzheimer's. But what are the scientific hurdles and what's missing in our knowledge in fuelling an ambition to achieve a disease modifying therapy for dementia? Adam Rutherford speaks to Cambridge University neuroscientist Rick Livesey, and to Eric Karran, Director of Research at Alzheimer's UKHow is it possible to remember something initially and then change your account of the experience later on? Possibly, giant swathes of your own personal history are partially fictional if not completely false. The problem isn't that our memory is bad, but that we believe it isn't. Adam talks to forensic psychologist Julia Shaw whose astonishing new research examines the ability to implant completely made-up rich false memories into ordinary people in a lab setting and points to circumstances under which police officers can extract false confessions.There's a visit to the UK's synchrotron light source at Harwell in Oxfordshire which since it started operations in 2007 has illuminating research on subjects ranging from Egyptology to virology and this year is opening its doors to the publicAdam meets Mark Kelly, one of NASA's twin astronauts taking part in a year-long space experiment to examine the impact of space travel using identical twins as subjects. With one twin orbiting on the International Space Station whilst the other remains confined to Earth, the aim is to examine how individuals with the same genetic profile respond to radically different environments - in particular the genomics of humans as they prepare to move away from their home planet.Producer: Adrian Washbourne.
Earth's Core; What Can Chemistry Do for Us?; Ocean Acidification; Darwin Day
Adam Rutherford explores new insights into what lies at the very centre of the Earth. New research from China and the US suggests that the innermost core of our planet, far from being a homogenous iron structure has another, distinct region at its centre. He talks to the study's lead researcher Xiangdong Song and to geophysicist Simon Redfern about what this inner-inner core could tell us about the very long history of the Earth and the long suspected swings in the earth's magnetic field.Professor Andrea Sella, from University College London is a recipient of the Royal Society's Michael Faraday Prize, in recognition, like Faraday himself, of exemplary science communication to the lay public. Andrea gave his prize lecture this week, describing chemistry as one of the 'crowning intellectual achievements of our age'. How justified is the claim? What have chemists ever done for us?The sea forms the basis of ecosystems and industries, and so even subtle changes to the waters could have serious knock on effects. Dr Susan Fitzer from the University of Glasgow has been wading into Scottish lochs to study shelled creatures; they form a vital basis for marine ecosystems and the global food industry. But what effects could ocean acidification have on this vital organism?And to mark Darwin Day Adam Rutherford examines the origins of Creationism and its most recent variation Intelligent Design. Why do opinion polls in the US routinely find that about half of the population denies the truth of Darwin's theory and believes instead that humans were created supernaturally by God at some point within the last few thousand years? He hears from historian Thomas Dixon, and from Eugenie Scott, former director of the National Centre for Science Education - a US organisation committed to keeping evolution (and now climate change) in the US schools' curriculum.Producer: Adrian Washbourne.
Goshawk, Cosmic Renaissance, Carl Djerassi and Charles Townes
As Helen MacDonald's "H is for Hawk" secures 2014's Book of the Year at the Costa Awards, a paper appears describing the hunting tactics of the Northern Goshawk, quite literally, from a birds' eye view. Suzanne Amador Kane of Haverford College in the US describes her work analyzing footage from tiny cameras mounted on the head of the predatory raptor.The Planck Consortium releases yet more findings from the very beginning of the universe. A new age for the very first stars confirms our best models of the universe. But analysis of the dust in our own galaxy edges out the possibility that last year's BICEP2 announcement did in fact represent evidence of inflation and the first observed primordial gravitational waves.And in the last two weeks, two giants of the twentieth century passed away. Science writer Philip Ball shares his thoughts on the lives of Carl Djerassi, father (he preferred mother) of the contraceptive pill, and Charles Townes, known as father of the Laser.Producer Alex Mansfield.
Climate change belief; Anthropocene era; Eyes on the sea; Origins of multicellular life
We all remember the floods across much of central and southern England this time last year, and the devastating effect they had on people's lives and livelihoods. Today, a group of researchers at Cardiff University published a report on how people's perception of climate change has evolved in the wake of the floods. To what extent has our belief in man-made climate change altered? Do we now regard last year's events as a sign of things to come? Adam Rutherford talks to Nick Pidgeon from Cardiff University's School of Psychology who led this UK wide studyEarlier this week an international group of climate scientists, geographers and ecologists met at the Stockholm Resilience Centre in Sweden to wrangle how we can practically make the best of the Anthropocene - the new geological epoch that many consider that we now find ourselves in. Gaia Vince author of Adventures in the Anthropocene, reports from the Stockholm meetingAt the UK's Satellite Application Catapult in Harwell, a project has been unveiled that seeks to offer real time data on the world's fishing fleet to help governments police illegal fishing. Pulling together data from shipping registers, satellite images, radar and ships' own transponders, Eyes on the Sea automatically scans for suspicious activity and can alert human users and allow them to see what ships are up to. The Pew Charitable Trusts hope that vessels carrying illegal cargoes can then be tracked across the ocean, and any port receiving them would know where they had been and what they had been up to.How complex cells evolved is a mystery. Current theories on the evolutionary jump, between 1 and 2 billion years ago, from life forms based on a simple prokaryote cell to the complex multiple eukaryote cells with a cell nucleus and a host of complex internal machinery, fails to explain much of what we see within animal, plant and fungi cells today. Adam talks to Buzz Baum a cell biologist at University College London who has devised a new testable model which appears to explain one of biology's most basic questions.Producer: Adrian Washbourne.
GMOs; International Year of Light; Coral health
It is likely that scientists will soon engineer strains of "friendly" bacteria which are genetically recoded to be better than the ones we currently use in food production. The sorts of bacteria we use in cheese or yoghurt could soon be made to be resistant to all viruses, for example. But what if the GM bacteria were to escape into the wild?Researchers writing in the Journal Nature propose this week a mechanism by which GMO's could be made to be dependent on substances that do not occur in nature. That way, if they escaped, they would perish and die.George Church, of Harvard Medical School, tells Adam Rutherford about the way bacteria - and possibly eventually plant and animal cells - could be engineered to have such a "failsafe" included, thus allowing us to deploy GM in a range of applications outside of high security laboratories. Adam reports from this week's launch in Paris of the International Year of Light marking 100 years since Einstein's Theory of General Relativity. Amongst the cultural and scientific events at UNESCO in Paris, Nobel Prize winner Bill Philips explains how using lasers can achieve the most accurate atomic clocks imaginable and we hear how Google X is embracing new ways to manipulate light to ignite some of the team's futuristic technologies And as the global decline in coral reefs continues as a result of human activity, Adam talks to Hawaii based biologist Mary Hagedorn who is using unusual techniques normally adopted for fertility clinics, to store and regrow coral species that are in dangerProducer: Adrian Washbourne.
International Year of Soils
This year is the Food and Agriculture Organisation's International Year of Soils.Adam Rutherford, ably assisted by Manchester University's Richard Bardgett, takes a look at new research seeking to further our understanding of soil behaviour that determines much of our existence.A handful of soil contains many tens of thousands of different species of microbial life, all competing to the death with each other for nutrients and resources. Yet most of those species are very poorly understood, because hitherto scientists have only been able to grow a small percentage of them in the lab.Last week's announcement of a new class of antibiotic - teixobactin - owes a lot to soil; Two buckets of it from the back garden of one of the researchers.Kim Lewis of Northeastern University in the US describes the new technique that could open up the whole biodiversity of a clump of soil to future medicines.Meanwhile, Monsanto, Novozyme and Morrone Bio in the US are just some of the big agricultural corporations exploring what useful microbes could be spread on seeds and crops to increase yields and reduce the needs for fertilizers.Soils, apart from feeding us and helping us fight disease, also have a crucial regulatory role in our climate.Sue Nelson reports on a new soil moisture monitoring network being set up in the UK that uses cosmic rays to measure the water content. The Cosmic-ray Soil Moisture Observing System, COSMOS-UK, is being set up by the CEH, based out of Edinburgh.On a global scale, soils are a hugely important reservoir of carbon. Iain Hartley of the University of Exeter talks about the vast amounts of carbon - more than all the carbon in all the trees and air - held in frozen soils in the far northern reaches of the earth. If these vast plains of permafrost were to melt in a warming world, the positive feedback loop caused by the resulting methane and CO2 released could be a bigger problem than many of our climate models allow for.But could we manage the soils beneath our feet better?David Manning of Newcastle University suggests that minerals could be added to brownfield (urban) soils to help them capture and sequester staggering amounts of CO2 from the air to help us offset anthropogenic emissions.Producer Adrian Washbourne.
Venus mission, Science highlights for 2015, Sonotweezers, Tsunami 10 years on
Adam Rutherford investigates the news in science and science in the news.This week's announcement of the discovery of 8 planets lying within the habitable zones of their stars has again raised the prospect of an earth like planet existing outside our solar system, But if we're to understand how "earth like" these exoplanets really are, we need to gain vital clues from earth's "evil twin" Venus argues environmental engineer Richard Ghail. Adam Rutherford hears about his proposed new mission to Venus - a planet orbiter to examine the surface and atmosphere that will allow us to understand why Venus has evolved so differently from earth despite their apparent sisterlike characteristicsIn the more immediate future science correspondent Jonathan Amos looks ahead to some of the highlights in astronomy and physics we can expect in 2015 - from the switch on of the newly energised Large Hadron Collider, and the imminent results of the successful Rosetta mission to the comet 67P, to the long awaited flyby this summer to capture images of Pluto.Roland Pease reports on a revolutionary method of controlling microscopic objects using sonics. As we move further into nanoscale technologies - electronic, mechanical and biological, and often a combination of all three - this could potentially offer a solution to manipulating structures, many of which are quite fragile at this scale.And ten years on from the shock of the South East Asian Tsunami that was to cost the lives of over 220 000 people Adam Rutherford speaks to Dave Tappin of the British Geological Survey, one of the first marine geologists who went to assess the cause of this seismic event. What have we learned in the intervening years?Producer Adrian Washbourne.
Listeners' Science Questions

Microplastics; Holey Ice; Vesalius; Overeating
Microplastics For the first time, scientists have studied the abundance of microplastics in deep sea sediments They have found that tiny fibres of plastic are everywhere and that levels found in the ocean sediments are 4 times higher than in contaminated sea-surface waters.Marine debris, mostly consisting of plastic, is a global problem, negatively impacting wildlife, tourism and shipping. However, despite the durability of plastic, and the exponential increase in its production, there was a considerable proportion of the manufactured plastic that was unaccounted for. But now scientists have found that deep-sea sediments are a likely sink for microplastics.Holey Ice You'd have thought, given how much water and ice there is around, that we'd know pretty much all there is to know about them. Among the notable facts is that ice is less dense than water - which is why it floats on your pond rather than sinking to the bottom. But like carbon - which exists in two distinct forms, diamond and graphite - the molecules in solid H2O can be packed in many different ways. And this week, scientists have found another completely different form of ice, which is perhaps stranger than all the others.Overeating Why do some people overeat? In order to find out, brave scientists tucked into 9000 calorie meals.Vesalius Andreas Vesalius, the founder of the modern science of anatomy was born 500 years ago, on the 31st December 1514. He was a proponent of, and yet, a strong critic of the ancient Greek physician Galen, who implied human anatomy from animal dissections. Vesalius challenged physicians and medical scholars to get their hands dirty and carry out dissections themselves.Producer: Fiona Roberts.
Water on Comets; DNA in Space; Sounds of the Ocean; Science in Fashion
Where does the Earth's water come from? It's thought that it arrived from space, carried by comets. But recent research suggests otherwise. Professor Katrin Altwegg is principal investigator in charge of Rosina - the tool on the recent Rosetta mission that is charged with answering this mystery.DNA can survive a trip into space, according to a recent experiment. Dr Lewis Dartnell, an astrobiologist from Leicester University, explains the implications.What sounds do the oceans make? Anand Jagatia reports. Dr Julius Piercy from the University of Essex listens to coral reefs. And his recent work could help us harness sounds to help restore damaged and dying coral reefs.This week, the new Nobel laureates head to Stockholm to pick up their medals. Among them is Norwegian neuroscientist Professor May-Britt Moser. The question on nobody's lips; what was she wearing? Which is a shame because she wore a Matthew Hubble dress featuring Grid Cells - our brain's positioning system. Discovering these grid cells won May Britt her Nobel prize. Polymer scientist Professor Tony Ryan from University of Sheffield talks fashion and science with Adam Rutherford.Producer: Beth Eastwood.
Orion Launch; Fake Mars trip; XDNA; Richard the Third's skeleton
A NASA space capsule, Orion, that could transport humans to Mars is due to make its maiden flight. Given that this is a first outing, there will be no people aboard. The capsule will orbit the earth twice in four and a half hours, before splashing down in the Pacific. BBC correspondent Jonathan Amos is on location at Cape Canaveral and gives Adam the latest news.This is a step towards a crewed mission to Mars. But how do humans cope with being confined for the 8 months it takes to get there? The European Space Agency studied this question in 2010. 6 volunteers were shut up in a replica space shuttle for over a year. Engineer Diego Urbina was one of them. He shares his thoughts on taking part in a fake Mars mission.Philip Holliger from the MRC Laboratory of Molecular Biology in Cambridge heads the team that two years ago built XNA, a set of genetic molecules that behave just like DNA, but are man-made. Like DNA, those XNAs didn't actually do that much, but this week, the team has published a paper where they have got them working. These are the first synthetic enzymes on Earth.Back in 2012, a shallow grave was uncovered underneath a car park in Leicester. Evidence suggested the skeleton in it was King Richard the Third. Finally this week, the DNA confirmation by geneticist Turi King is in. And something is rotten in the state of his lineage. Kevin Schurer, historian, and Richard Buckley, the lead archaeologist on the dig, talk us through the DNA anomaly that hints at infidelity in the royal line.
Campylobacter in Chicken; Artificial Intelligence Guru Demis Hassabis; Sexology; Lucy
Food Standards Agency report reveals 70% of supermarket chicken contaminated. Chicken: It's the nation's favourite meat. But today, a report released by the Food Standards Agency has revealed that around three quarters of that chicken is infected by campylobacter - a family of bacteria, 12 species of which are known to cause food poisoning. The estimated cost to the UK economy is £900 million per year. All supermarkets are implicated and all supply chains too. It doesn't cause outbreaks and thorough cooking kills all the bugs. Professor Hugh Pennington tells Dr Adam Rutherford why campylobacter is such a tough bug to crack. Can machines think? Neuroscientist, chess master and world-champion gamer, Demis Hassabis is this week's winner of the Royal Society's Mullard Award. In 2011, he founded an AI company, Deep Mind which was acquired by Google earlier this year for £400million.He tells Adam why he believes one of the best tests for artificial intelligence is an ability to learn how to play computer games. Why scientists study sex Sex between humans has long been something of a taboo for scientists. But the Institute of Sexology is tackling it head-on. It's a new exhibition at London's Wellcome Collection, a frank exploration of sex and the scientists who've studied it for the past century or so. Tracey Logan went to preview the display, and asked: Why do scientists study sex? Australopithecus discovery 40 years on 23rd November 2014 was a significant 40th birthday. Or, to be a bit more precise, it was a 3 million, 200 thousand and 40th birthday. On that day in 1974, Donald Johanson and his team in Ethiopia discovered the fossilised remains of AL 288-1, who became universally known as Lucy. Don talks to Adam Rutherford about the young woman who changed his life.Producer: Anna Buckley & Fiona Roberts Assistant Producer: Jen Whyntie.
Comet landing detects organics molecules; Lunar Mission One; Biological warfare
Philae lander detects organic molecules on Comet 67P Rosetta scientist, Professor Monica Grady from the Open University discusses the latest news from last week's historic comet mission. Philae, the Rosetta robot probe, made history last week when she finally landed on the surface of Comet 67P. But she ended up lying on her side, and only in partial sunlight. Her batteries were on borrowed time. After around 60 hours, Philae powered down, and went into hibernation mode. However, her instruments harvested some data and now the first results are in.UK-led crowdfunded Moon mission Lunar Mission One aims to land a robotic spacecraft on the unexplored lunar South Pole by 2024. It's a space mission with a difference: it could be funded by you. For a small fee supporters can send a human hair to the Moon in a Blue Peter-style time capsule. And the spacecraft will drill up to 100 metres below the surface to ask questions about the Moon's origin, aiming to find out more about the minerals that exist there, several of which are potentially valuable. Our reporter Sue Nelson went to the British Interplanetary Society's Reinventing Space conference in London to hear more.The Selfish Gene debate As another bout of biological warfare breaks out between two scientific superpowers, Adam Rutherford gets to grips with evolutionary theory, with social insect expert Professor Adam Hart. He hears from Richard Dawkins and E.O. Wilson and finds out why, after forty years of promoting the idea of kin selection, E O Wilson now dismisses the whole idea as 'rhetoric'.Presenter: Adam Rutherford Producer: Anna Buckley Assistant Producer: Jen Whyntie.
Rosetta; Thought-controlled genes; Biophonic Life; Arecibo message 40 years on
Rosetta After a nail-biting, bumpy, bouncy landing, European Space Agency's Rosetta probe - 'Philae' -lands on the comet 67P. It's already collecting data and beaming back some very impressive images of this dusty, icy space projectile. BBC Space correspondent Jonathan Amos fills us in on the latest news.Thought-controlled genes Brainwaves from human participants activated a light, which in turn switches on specific genes in mice. In this proof of concept study, Professor Martin Fussenegger hopes that one day this technology could be used to control pain, pre-empt epileptic seizures, or in fact communicate with people who have locked in syndrome. It's another example of two very exciting techniques - brain machine interfacing and optogenetics.Arecibo Message Anniversary 40 years ago, on 16 Nov 1974, a message designed to inform intelligent alien civilisations about human existence was beamed into space. Whilst Frank Drake's binary picture message was primarily put together to show the capabilities of the upgraded Arecibo radio telescope in Puerto Rico, it has inspired interest and enthusiasm around the world. Veteran of subsequent space message projects Dr Carolyn Porco joins Adam to talk about how space science has progressed in the interim decades, and what these ventures mean to humankind.Biophonic Life Sound installation "The Sounds of Others: A Biophonic Line", by artist Marcus Coates is currently delighting visitors to Manchester's Museum of Science and Industry. It explores the sounds of animals, from field crickets to humpback whales. By speeding and slowing each sound, his work reveals unimagined connections between species, and unearths common patterns and forms that would normally be beyond the reach of the human ear. The Sounds of Others looks for commonality between the human and non-human worlds, through sound. Marcus Coates, and collaborator wildlife sound-recordist Geoff Sample talk Adam through some of the surprising sounds of nature. Can you tell a pack of children from red deer? Or Marcus from a Lion? And is there a reason for these connections?Producer: Fiona Roberts.
Science of ageing; Microneedles; Firelab; Rosetta; Scientific authorship
What is ageing? In 1900, the global average life expectancy was 31, today it's 70, and the number of people over 85 in the UK is predicted to double in the next 20 years. How has ageing evolved, and do we know what is happening in our cells as we age? Professor Richard Faragher, University of Brighton, explains.Sticking plaster-like needle replacement Microneedles on a sticking-plaster-like patch may be the painless and safe way doctors will test for drugs and infections, and give vaccinations in the future. Roland Pease tries an alternative to the traditional injection at Queen's University Belfast with Dr Ryan Donnelly.Science of fire It's November, and these are the days when you may well have a smouldering bonfire in your back garden. Marnie Chesterton meets scientists whose lives are devoted to the behaviour of fire.Comet landing mission nears The Rosetta Mission is entering the final stages before landing on a comet. By this time next week, we will know if the European Space Agency has successfully achieved what could be an extraordinary feat.

The Making of the Moon
It's the nearest and most dominant object in our night sky, and has inspired artists, astronauts and astronomers. But fundamental questions remain about our only natural satellite.Where does the Moon come from? Although humans first walked on the Moon over four decades ago, we still know surprisingly little about the lunar body's origin. Samples returned by the Apollo missions have somewhat confounded scientists' ideas about how the Moon was formed. Its presence is thought to be due to another planet colliding with the early Earth, causing an extraordinary giant impact, and in the process, forming the Moon. But, analysing chemicals in Apollo's rock samples has revealed that the Moon could be much more similar to Earth itself than any potential impactor. Geochemist Professor Alex Halliday of the University of Oxford, and Dr Jeff Andrews-Hanna, Colorado School of Mines - who is analysing the results from NASA's Gravity Recovery and Interior Laboratory (GRAIL) lunar mission - discuss the theories and evidence to-date.Are we going back? Settling the question of the Moon's origin seems likely to require more data - which, in turn, requires more missions. BBC Science correspondent Jonathan Amos tells us about the rationale and future prospects for a return to the Moon, including the Google Lunar XPrize.As the Moon's commercial prospects are considered, who controls conservation of our only natural satellite? If commerce is driving a return to the Moon, who owns any resources that may be found in the lunar regolith? Dr Saskia Vermeylen of the Environment Centre at Lancaster University is researching the legality of claiming this extra-terrestrial frontier.Producer: Jen Whyntie.
Hobbit; Genetics of height; Solar science; Snails
It's 10 Years since an unusual skeleton was unearthed on the island of Flores. This species, Homo floresiensis, dubbed 'the Hobbit' because of its short stature, offered a whole new picture of human evolution and has been causing divisions among scientists ever since. Lucie visits Professor Chris Stringer in the Natural History Museum to pick over the bones of a controversial find.Tall parents tend to have tall children. We already know that height is genetic. Less well known is how various genes control the growing process. Recent research from the University of Exeter found nearly 700 genetic variants that play a role in influencing a person's height. Professor Tim Frayling, a lead author, explains how the work, which involve scanning more than a quarter of a million genomes, could help with disease, forensics and predicting a child's adult height.Great ball of fire. The Sun throws out more than just light and heat; for solar scientists, it is also a source of many mysteries. Why is the surface of the sun less hot than its corona, or outer atmosphere? New research using the NASA satellite telescope, IRIS, or the Interface Region Imaging Spectrograph is providing new insights.Earlier this month, a group of more than 100 snail experts (malacologists) from across Europe gathered in Cambridge to discuss the latest research into molluscs - the group of animals that includes everything from squid and octopus in the seas to slugs and snails on land. After three days of lectures, the malacologists were let loose in the Cambridge Botanic Gardens. Reporter Helen Scales went with them on a snail hunt.Producer - Fiona Roberts.
Ebola; Ada Lovelace Day; Space Weather
Ebola Outbreak As the World Health Organisation announces that the situation in Guinea, Liberia and Sierra Leone is deteriorating, with widespread and persistent transmission of Ebola Virus Disease, the UK has introduced screening measures at Heathrow airport for passengers arriving from Ebola-affected countries. How has this particular outbreak become so widespread, and where did it start? Lucie Green discusses the source, spread and science of Ebola with Jonathan Ball, Professor of Molecular Virology at the University of Nottingham.Ada Lovelace Day Leading the charge in inspiring and celebrating women scientists, technologists and mathematicians is 19th century computer programmer Ada Lovelace. Daughter of poet Lord Byron, collaborator with inventor Charles Babbage, and accomplished mathematician herself, October 14th has been set aside for Ada Lovelace Day. Event founder Suw Charman-Anderson tells us more.Space Weather The Met Office Space Weather Operations Centre is designed to protect the UK from severe problems caused by space weather. It's been known since 1859 that weather in space can cause problems on Earth, but scientists say our growing dependence on technology puts us at greater risk. Our satellites, power grids and radio signals are all vulnerable to damage from extreme space weather events. Lucie Green heads down to the new space weather centre in Exeter, to see how they monitor the sun's activity, and how that translates into an extra-terrestrial forecast.Producers: Fiona Roberts & Marnie Chesterton Assistant Producer: Jen Whyntie.
Nobel Prizes 2014; Gauge; Genetics and Diabetes; UK Fungus Day
Nobel Prizes 2014 The annual Nobel Prizes for Physiology or Medicine, Physics and Chemistry were announced this week.The Nobel Prize for Physiology or Medicine has been awarded to UK-based researcher Prof John O'Keefe as well as May-Britt Moser and Edvard Moser who discovered the brain's "GPS system". They discovered how the brain knows where we are and is able to navigate from one place to another. Their findings may help to explain why Alzheimer's disease patients cannot recognise their surroundings.The 2014 Nobel Prize for physics has been awarded to Professors Isamu Akasaki, Hiroshi Amano and Shuji Nakamura in Japan and the US, for the invention of blue light emitting diodes (LEDs). This enabled a new generation of bright, energy-efficient white lamps, as well as colour LED screens.The 2014 Nobel Prize in Chemistry has been awarded to Eric Betzig, Stefan Hell and William Moerner for improving the resolution of optical microscopes. This type of microscope had previously been held back by the presumed limitation that obtaining a better resolution than half the wavelength of light would be impossible. But the laureates used fluorescence to extend the limits of the light microscope, allowing scientists to see things at much higher levels of resolution.GAUGE The UK has a database for the amount of greenhouse gases we emit each year - usually measured in Gigatonnes of carbon. It's compiled by adding up emissions from various individual sources - be it a coal-fired power station or a wetland bog. This amount is used worldwide, but it is an estimate. A project called Greenhouse gas UK and Global Emissions, or GAUGE, is - for the first time - verifying these estimates by measuring what's in the atmosphere on a much larger scale.Genetics and Diabetes Type 2 diabetes is globally the fastest growing chronic disease. The World Health Organisation estimates more than 300 million people are currently afflicted, rising to more than half a billion by 2030. It might seem on the surface to be a disease with a simple cause - eat too much & exercise too little - and the basic foundation is a relative lack of the hormone insulin. But as with most illnesses, it's much more complicated, not least because a large number of disease processes are happening all at once. In 2010, a particular gene variant was associated with around 40% of Type 2 diabetics - not directly causal, but this so-called 'risk variant' increases the chance of developing the condition if you have the wrong lifestyle. Research published in the journal Science Translational Medicine this week identifies a drug called yohimbine as a potential treatment to help Type 2 diabetics, one that targets this specific genetic make-up.UK Fungus Day October 12th is UK Fungus Day, a chance for us to celebrate these cryptic, often microscopic, but essential organisms. Usually hidden away inside plants or in soil (or if you're unlucky, in between your toes), fungi have largely been growing below scientists' radars for centuries. Mycologists still don't know anything close to the true number of fungi that exist on the planet. About a hundred thousand have been formally identified, but it's estimated that anywhere from half a million to ten million species may exist. This dwarfs, by several orders of magnitude, how many mammals there are on Earth. And, increasingly, we're realising quite how crucial fungi are to the functioning of our ecosystems. Head of Mycology at The Royal Botanic Gardens Kew, Bryn Dentinger, explains how valuable fungi really are.Producer: Fiona Roberts Assistant Producer: Jen Whyntie.
Women, Science and the Royal Society; Open Access Research
Royal Society investigates the decline in their awards to female scientists Last week, the UK's national science academy, the Royal Society, announced its latest round of University Research Fellows (URFs). And they are almost all fellows - in the male sense of the word. Out of 43 new posts, only two of them are women. These positions are for early-career, post-doctoral researchers. But, at the top of the tree, fewer than one in ten science professors are women, and one of the top UK scientific accolades - a Royal Society Fellowship - is held by only one in twenty. To their credit, The Royal Society were "horrified" by this latest round, and their president, Sir Paul Nurse, immediately called for a full investigation into how this happened, saying "this sends out a bad message to young female scientists".Our reporter Tracey Logan asks why Royal Society grants are so important to young scientists, and whether this year's number of female recipients is a sign of gender bias on the awarding committees, or just a statistical blip in a fair process? And Adam Rutherford meets Professor Julia Higgins to hear the latest just after participating in a diversity working group meeting at the Royal Society in London.Getting science out from behind paywalls You pay for science research via your taxes, but you may not get to see the results unless you pay again to read the journals that publish them. With two major UK science publishers, the Royal Society publishing and Nature, announcing one apiece of their journals are going fully open access -broadly, free for anyone to read online - we're discussing the way science makes it from the lab to the public, via the ever controversial system of publishing and peer review. Adam is joined by Fiona Godlee, Editor of the British Medical Journal; Lesley Anson, Chief Editor of Nature Communications; and Chris Lintott, Professor of Astrophysics and Citizen Science Lead at the University of Oxford.Producer: Fiona Roberts Assistant Producer: Jen Whyntie.
Cosmic inflation latest; Indian space success; Science and language; Wax Venus
BICEP - gravitational waves and dust One of the biggest scientific claims of 2014 has received another set-back. In March this year, the BICEP2 research team claimed it had found a swirling pattern in the sky left by the rapid expansion of space just fractions of a second after the Big Bang. This announcement was quickly criticised by others, who thought the group had underestimated the confounding effects of dust in our own galaxy. And now, new analysis from the European Space Agency's Planck satellite suggests dust found in our own galaxy may have confounded what was thought to be a universal revelation.India's Mars satellite enters orbit India has successfully put a satellite into orbit around Mars, becoming the fourth nation or geo-bloc to do so. Following a few teething troubles with a planned engine burn shortly after launch on 5 November 2013, and a long journey, the Mangalyaan probe has started sending back images of the Red Planet. It is the first time a maiden voyage to Mars has entered orbit successfully and it is the cheapest mission to-date.Science of language Professor Steven Pinker talks to Adam Rutherford about the language of scientists and the science of language. He has a new book out, "The Sense of Style: The Thinking Person's Guide to Writing in the 21st Century", discussing how the latest research on linguistics and cognitive science can improve writing.The Anatomical Venus Adam visits the Wellcome Collection to see an 18th-Century Florentine Wax Venus - complete with removable abdominal organs. He discusses our preoccupation with death, with Joanna Ebenstein. And finds out if these beautiful, if slightly unnerving, statues were the cutting edge of anatomical learning, or a gory sideshow.Producer: Fiona Roberts Assistant Producer: Jen Whyntie.
European ancestry; Cern is 60; Graphene plasters; Penguins
European Ancestry New genetic investigation of ancient human remains, combined with archaeological evidence, is shedding new light on the origins of the early European populations. The international team has provided a detailed analysis of waves of immigration from the near east into Europe, and the emerging agricultural practices that came with it, which has come to dominate the traditional practices of indigenous residents.CERN - Artificial retina The human eye and the parts of the brain that process images are second to none when it comes to pattern recognition and concentrating on the important images and ignoring the rest. They have inspired physicists to create a processor that can analyse particle collisions 400 times faster than any other device. In these collisions, protons, that is, ordinary matter, are smashed against protons at close to the speed of light. These processes may produce new particles and help scientists understand matter's mirror - antimatter. Professor Tara Shears, a particle physicist at the University of Liverpool, explains how this algorithm could help sift through data from collisions at the Large Hadron Collider at CERN.Graphene plaster Since it was discovered 10 years ago, the wonder material graphene has taken the world by storm. What's not to like about it? A sheet of carbon one-atom thick, it was the first two-dimensional material discovered. It's stronger than steel, conducts electricity better than copper. We are told it will be used in touch screens of the future. It may be the secret to miniaturising electronics when current chip technology runs out of steam. But at the other end of the technology market a team at Surrey University has found it useful to blend graphene with rubber bands to make cheap effective bio-sensors.Penguins In a new citizen science project, 'penguinologists' are asking the public to classify images of penguin colonies in Antarctica, to help the team monitor their health. Thousands of images taken by remote cameras monitoring over 30 colonies around the Southern Ocean are being posted online. We hear why penguins are at risk from habitat and climate change and what the public can do to help.Producer: Fiona Roberts.

Jack the Ripper "identified" Some of us are morbidly fascinated by the legend of Jack the Ripper - not the world's first serial killer, but the one that coincided with the birth of mass media, and set the ghoulish tone for the 20th century's obsession with murderers. This week a shawl acquired at an auction in 2007 is in the spotlight. Claimed to be found in 1888 at the murder scene of a woman asserted to be the fourth victim of the supposed Ripper, DNA evidence from the fabric is stated to imply one of the most plausible suspects - Aaron Kosminski. However, there are many problems with this "identification" sequence - some historical, some legal, and some scientific. Adam Rutherford focuses on the science by speaking to Jari Louhelainen, a forensic geneticist at Liverpool John Moores University, who produced the forensic analysis. Jon Wetton, another forensic geneticist at the University of Leicester, offers broader insight into how DNA can be used in detecting crime.Future of Scottish science Scottish science has a rich history: Alexander Fleming, James Watt, Dolly the sheep and much, much more. This week, with the upcoming referendum on independence, Dr Adam Rutherford takes the opportunity to look at the future of science in Scotland. He's joined by scientists representing the Academics for Yes and Better Together campaigns. Making the case for independence are Dr Stephen Watson and Professor Mike Lean, both from the University of Glasgow. Dr Patrick Harkness, also from the University of Glasgow, and Professor Hugh Pennington, emeritus professor at the University of Aberdeen, make the case for remaining in the union.Producer: Fiona Roberts.
Bardarbunga volcano; Geology in Minecraft; Synthesising opioids; Ammonia
Bardarbunga A group of earth scientists was in Iceland performing annual maintenance of its equipment, when the volcano Bardarbunga erupted. Professor Simon Redfern has now joined them and speaks to Adam Rutherford from the slopes of neighbouring volcano Askja. He explains how all this recent volcanic activity is the expression of Europe's tectonic drift away from America. And rather than this being a smooth, continuous process, the plates move at the surface in a jerky way - causing these earthquakes and volcanic eruptions.Geology in Minecraft The British Geological Survey has built a full version of the geology of Britain into the online game Minecraft. Minecraft is a so-called 'sandbox' game, meaning there are no specific objectives, but players are free to explore existing worlds or collaborate to build their own with a range of virtual building blocks. The game is a huge phenomenon, with over a 100 million registered users, mostly under the age of 30. By adding an extra layer of geological features, the BGS hopes to encourage interest and add a further dimension to the game.Synthesising opioids Opiates such as morphine are commonly used in pain-relief medicines, but their chemical complexity means that commercial production is limited and the pharmaceutical industry has to rely on extracting them from poppies. However, researchers at Stanford University are working on a synthetic-biology system using yeast to produce opiates like morphine, and the pharmacologically more attractive opioids like hydrocodone and oxycodone. They haven't got all the steps in the pathway in place yet. But they're not far off.Ammonia In recent years there's been renewed interest in ammonia, as a fuel. It could work as a replacement for petrol and diesel in cars with very little engine change. In fact it was used as such during the Second World War in Belgium.Producer: Fiona Roberts.
Manipulating mouse memory; London pollution; Nature of knowing; Snail fur
Manipulating mouse memory Optogenetics allows researchers to use light to turn the genes involved in memory, in the brain, off and on. It's a powerful tool for seeing exactly where specific types of memory are formed and processed. Researchers at MIT have been using the technique to manipulate fearful or pleasurable memories associated with a particular location, in mice. This is so they can see how memories are overwritten in the brain's processing regions.London pollution Cities in Britain have moved on a great deal from air pollution events, like the London smog of 1952, where 4000 people died in a week. But a recent report has put London air pollution levels as bad as some of the worst in the world, on a level with Mexico City and Beijing. Pollution is a mixture of gases and tiny particulate matter (or PM) -particles too small to be filtered out by our noses, and which end up going straight into our lungs. Dr Rossa Brugha and reporter Marnie Chesterton take a bicycle ride through London's busy streets and parks with an air pollution monitor. Back in the studio, Rossa and Adam talk through the results...Nature of knowing Philip Ball, the programme's on-call polymath and author of 'Invisible, the Dangerous Allure of the Unseen', comes into the studio to answer a listener's question about how science can possibly understand the unseeable, if it is supposed to be dealing with the observable universe.Snail fur and how to grow a new head Why is it that some animals can regrow lost body parts and others, like us, can't? Even some closely related species, for instance salamanders, can regrow a lost tail, but fellow amphibians, the frogs, can't regrow lost legs? One of the best-studied 're-generators' is the sea creature - Hydractinia, or Snail fur, because it grows like fur on the back of the snail-shell homes of hermit crabs. By studying Hydractinia's regenerative powers at the cellular level, researchers think that most animals, including us, may have the potential to regrow lost limbs using stem cell systems lying dormant within us.Producer: Fiona Roberts.
TB in the New World; Trusting Wikipedia; Shipwreck of the London; @LegoAcademics
TB in the New World Brand new work in comparative genetics is shedding light on the spread of TB. Scientists have shown that the initial spread of the deadly bacterial disease tuberculosis to the Americas didn't come with the European explorers and invaders. Skeletons of pre-Columbian Peruvians have shown signs of TB. So where did it come from? DNA samples collected from the ancient bacteria show they're closely related to the TB strain that infects seals and sea lions. So did the disease pass from humans in Africa to seals on the coast which then crossed the ocean and infected the Peruvians, 1000 years ago?Truth, Trust and the internet A recent YouGov poll revealed that the British public trusts the online encyclopaedia Wikipedia more than it trusts the BBC. The internet has revolutionised how we receive information and check references. But how much should we trust online facts? Adam talks to Carl Miller, from the Centre for Analysis of Social Media at think-tank Demos, about how Wikipedia entries are created and regulated. And he asks him whether the democratisation of facts - created by crowd-sourced opinion rather than individual experts - is something we should welcome?Shipwreck of the London The London was a 64-gun second-rate ship of the line of the English Royal Navy, launched in June 1656 and commanded by Captain John Lawson. The ship was accidentally blown up in 1665 and sank in the Thames Estuary. The wreck was rediscovered in 2008, and is considered important partly for its historical references and partly for its insight into an important period in British naval history. English Heritage and Cotswold Archaeology are examining the remains in the murky Thames estuary before they decide what to do next. Although the wreck could be at risk from increasingly acidified water and invasive shipworm, it's thought unlikely that they will raise the ship, due to a lack of museum space.Lego Academics Campaigns for better female scientist role-models are not new. But what is new and welcome is when industry and society listens. Plastic toy brick manufacturer, Lego, has recently come up with a new set called the 'Research Institute' and it consists of lab kit and three female scientists - a palaeontologist, an astronomer and a chemist. Real life scientist and archaeologist Donna Yates, from the University of Glasgow, has gained thousands of Twitter followers after posting photographs reflecting the daily frustrations of academic life using the Lego figures. She arranges them in academic scenarios and posts her pics to the @LegoAcademics account. It's fun and full of in-jokes, but it gives great insight into some of the real issues scientists, and in particular, female scientists face. A Lego version of Adam Rutherford conducts the interview.Producer: Fiona Roberts.
Anaesthesia; Chilean earthquakes; Strange weather; Jellyfish
Anaesthetics. General anaesthetic is an essential part of modern medicine. Millions of surgical procedures, many life-saving, simply could not be performed without rendering the patient unconscious with one of a long list of drugs that induce anaesthesia. But, we don't know how they work. Part of this mystery is because we're not entirely sure what we mean when we say unconscious. But part of it is that there's a whole fleet of different molecules than can work as an anaesthetic, so there's no well-known pathway we can study. Neuroscientist, Luca Turin at the Alexander Fleming Research Center in Greece thinks that the answer to how they work, could lie, not at the chemical level, but at the quantum level.2014 Iquique Earthquake in Chile Before the massive 8.1-8.2 Magnitude earthquake struck Iquique in Chile, in April, this year, there were a series foreshocks at the fault line. Adam Rutherford asks Roland Pease if these creaks could be a way of warning us about an imminent big quake in the future. They also discuss whether the stress released by the megathrust quake means the region will be seismically inactive for a while. The experts think not.Strange Weather We are obsessed with the weather. It is a powerful, shared daily experience, offering us an immediate talking point. Yet when we talk about climate change the sense of guilt or powerlessness can often be enough to kill the conversation. A new exhibition at Science Gallery at Trinity College Dublin aims to engage conversations about both weather and climate in a playful, provocative way. By bringing together works by artists, designers, scientists, meteorologists and engineers STRANGE WEATHER asks questions such as: Should human culture be reshaped to fit strange weather or should we reshape weather to fit our strange culture? Who is going to take advantage of climate chaos and how will strange weather benefit me? How will you choose to work, celebrate, live and die when weather gets weird?Strange Weather runs at Science Gallery, Trinity College Dublin from 18th July to 5th October 2014 Neutrinos A listener writes in to ask if we will ever run out of room in our Universe for the trillions and trillions of neutrinos being created. Malcolm Fairbairn at Kings College London does the maths.Jellyfish Last year was a record for jellyfish sightings off the UK coast. We know very little about our jellyfish, and experts at the Marine Conservation Society want to know more. They're set up a survey, complete with photographic guides and reporting forms for you to send in your sightings of these coastal visitors.Producer: Fiona Roberts.
New dinosaur; GM chickens; Lightning; Rosetta; Diatoms
Dinosaur A jumble of bones found in Venezuela belong to a group of very early dinosaurs, that could have been herd animals. Paul Barrett from the Natural History Museum explains to Professor Alice Roberts how a jumble of bones found in a 'bone bed' belong to a number of individual Laquintasaura venezuelae dinosaurs. They are an ancient, small, omnivorous dinosaur, which could have survived the Tertiary/Jurassic extinction event 200 million years ago.Genetically Editing Chickens Diseases devastate livestock around the world. In chickens for example the deadly strain of bird flu and the lesser known bacterial infection Campylobacter, does not only harm the chickens but is also a real threat to human health and welfare. Scientists are continually trying to develop vaccines, but the strains of bacteria keep evolving resistance to them. One of the solutions being explored at the Roslin Institute in Edinburgh, is genetic. Using a subtle form of genetic modification, called genome editing. The team are trying to find the genetic components of natural resistance in a wide group of chicken breeds, which they can then insert into the genome of livestock fowl in the hope of breeding healthier, safer chickens. Lightning A listener asks why lightning is jagged. Rhys Phillips from Airbus Group in Cardiff makes lightning in a lab. He has the answer.Rosetta The European Space Agency's robotic spacecraft Rosetta has reached the orbit of the comet Churyumov-Gerasimenko, and is about to start its detailed study. In the audacious and risky mission, the craft will follow the orbit of the comet as it approaches and passes the Sun. It will attempt to land a probe on the surface of the icy, rocky mass. It's hoped the mission will provide great insight into what comets are made of, how they behave as they heat up, creating its gassy coma and tail. And it's hoped Rosetta and its lander will be able to tell about where Earth's water and even some of the building blocks for life might have come from.Diatoms A type of phytoplankton, found in water, called Diatoms build hard silicon-based cell walls. Researchers, at the University of Galway, have shown it's possible to chemically transform the shells of living diatoms so they could carry drugs into our bodies in entirely new ways.

ExpeRimental; Rosetta; MOOCs
ExpeRimental There's an online wealth of science demonstrations you can try at home with your kids. But what's sometimes lacking is the encouragement of questioning the science in these DIY experiments. Science teacher and film maker Alom Shaha has devised a series of videos with the Royal Institution showing parents experimenting with home-made lava lamps, bubbles and bottle cannons. He hopes that amidst the mess and mistakes, some scientific thinking can be nurtured.Rosetta The European Space Agency's robotic spacecraft Rosetta is about to start its detailed study of the comet Churyumov-Gerasimenko.

And it's hoped Rosetta and its lander will be able to tell about where Earth's water and even some of the building blocks for life might have come from.MOOCs Massive Open Online Courses are free and open to anyone with access to the internet. You can study a huge range of topics from cancer and dental photography to quantum physics, and even the archaeology and history of Hadrian's Wall. Critics say these higher education courses are just a PR exercise by universities, and that it will set up a two tier system in education. But Kathryn Skelton from FutureLearn, a platform for many of these MOOCs, argues that they encourage people who would not normally extend their education to take part and the universities providing the courses can gain great insight into the changing face of teaching methods.Evolutionary Psychology Last week Adam Rutherford and Alice Roberts had a robust discussion on the biologising of the human condition, with Professor David Canter. Listeners wrote in to complain that we didn't give an evolutionary psychologist a right to reply, so this week, listener and evolutionary psychologist Rob Burriss has his say.Producer: Fiona Roberts.
