Face recognition The software that analyses images of your face, captured online or when you're out and about, has rapidly improved. Adam visits Amscreen, to test the cameras they deploy at supermarket checkouts to determine your age and sex, to inform advertisers of the best demographic to target. This raises ethical and privacy issues which Adam discusses with privacy expert Professor Colin Bennett and author of "The formula, about algorithms and the algorithm culture", Luke Dormehl.Quantifying expressions Is a look of contempt, or a smile, a universal expression or do they vary across cultures? Marnie Chesterton visits Glasgow University's Institute of Neuroscience and Psychology, where the scientists are building a huge database of faces, in order to unpick and quantify our expressions. Dr Oliver Garrod from the Generative Face Grammar Group demonstrates how they can capture your face, and animate it.Evolutionary psychology There is a long list of evolutionary explanations for the human condition. Mostly these are quite trivial. Teen boys develop acne on their faces to deter females from fertile but psychologically immature mates. Babies cry at night to prevent parents further procreating, resulting in potential sibling rivals. At the other end of the scale, these sorts of explanations have been used to suggest deeply problematic ideas, such as rape being an evolutionary strategy.Professor David Canter, a psychologist from University of Huddersfield has railed against this fashion for 'biologising' our behaviour. And evolutionary biologist Professor Alice Roberts is also critical of 'adaptionism' - the idea that everything has evolved for an optimal purpose.Producer: Fiona Roberts.

Plants and bees The relationship between flowering plants and bees is a long-evolved, complex one. Plant scientists at the Royal Botanic Gardens at Kew are currently conducting field trials to see how Acontium, or Monkshood, uses toxins to protect itself against nectar-thieving, short-tongued bumblebees. But how does it make sure it doesn't poison the helpful, pollinating long-tongued bumblebees?Plants from Roots to Riches Professor Kathy Willis, Director of Science at the Royal Botanic Gardens Kew will be presenting a new series on BBC Radio 4 exploring our relationship with plants from the birth of botany through to modern day. She describes some of the series highlights.The Azolla Event A tiny ancient fern-like pond weed could have been responsible for changing the fate of the planet. Some scientists think that Azolla could have played a significant role in reversing an increase in the greenhouse effect that occurred 55 million years ago. The researchers claim that massive patches of Azolla growing on the (then) freshwater surface of the Arctic Ocean consumed enough carbon dioxide from the atmosphere for the global greenhouse effect to decline, eventually causing the formation of ice sheets in Antarctica and the current "Icehouse period" which we are still in.Chomping caterpillars Plants can hear. Well, they can sense sound-vibrations. New research from the University of Missouri shows that when the mustard-like Arabidopsis senses the chomping sounds of a caterpillar munching on leaves, it primes itself for a chemical response.Composting low down A listener asks why orange peel takes so long to rot down in the compost heap? Is it because it's an exotic fruit? Adam asks Kew's Head of Horticulture and 'keeper of the heap' Dave Barns.Producer: Fiona Roberts.

Airport security has been tightened recently. Passengers must be able to switch on their electronic devices to prove they don't contain explosives. Inside Science asks about the science behind spotting a potential terrorist. Adam asks whether behavioural profiling works. Can trained security staff tell the difference between a nervous traveller and a potential terrorist?Light and colour in art Pigments and paint evolved over time, and these changes are one focus of the 'Making Colour' exhibition at the National Gallery. Different paints fade and degrade in different ways; often the patina of age is what appeals when looking at art, so how do you decide which hue to use when restoring paintings? Another intriguing issue is how you light a painting. The National Gallery is moving away from tungsten lighting, to more modern, tuneable LED lights. How does this affect the way visitors view the art? An interactive experiment is helping them to unpick light perception.Hadrian's Wall A listener asks how did the Romans knew where to build the great defensive wall. We get the answer from Professor Ian Haynes, an archaeologist at Newcastle University, who reveals that the Romans were obsessed with measuring.Cassini mission to Saturn Cassini-Huygens is an unmanned spacecraft sent to the planet Saturn. The NASA-ESA-ASI robotic spacecraft has been orbiting and studying the planet and its many natural satellites for 10 years. Adam talks to the mission's leader of the imaging science team, Carolyn Porco, about how successful it's been. And he offers her a blank cheque to choose her next mission.Producer: Fiona Roberts.

Informed consent Facebook has been under fire for running a controversial 'emotion manipulation' study on 689,003 Facebook users. The experiment, to find out whether emotions were contagious on the social network, involved minor changes to users' news feeds. It's contentious because the users were not informed that they were taking part in an experiment. Facebook says, check the terms and conditions, but Dr Chris Chambers at Cardiff University says that the ethical standards for science are higher, and should involve informed consent. Dan O'Connor, Head of Medical Humanities at the Wellcome Trust, gives a short history of consent in experimentation.El Nino According to the Met Office, the world is almost certain to be struck by the "El Nino" phenomenon this year, with the potential to induce "major climactic impacts" around the world. Roland Pease investigates this flip in the climate state of the Pacific basin, and asks the experts studying this phenomenon, whether it'll be a major event and how it might affect the climate.Gravitational Waves The announcement, earlier this year, that the BICEP 2 telescope at the South Pole had detected evidence that gravitational waves exist may have been premature. Gravitational waves are theoretical phenomena, based on observation of polarisation of ancient cosmic light. Finding them, adds to the evidence that the Universe is expanding. The data has now been made public, but the confidence in the numbers is being questioned.Cloud cover A listener asks about cloud cover and night time temperatures, and how air temperature and moisture content interact. Our expert Peter Sloss from the Met Office answers.Producer: Fiona Roberts.

Longitude Prize 2014 Winning Challenge Antibiotics resistance has been selected as the focus for the £10m prize. The World Health Organization (WHO) has warned of a "post-antibiotic era" where key drugs no longer work and people die from previously treatable infections. The next step in the challenge is to tackle this resistance, by developing a simple, cheap, quick test that allows you to tell whether an infection is bacterial or not. This will conserve the 50% of antibiotics that are currently given in situations where they have no effect.Solar Cells A popular form of photovoltaic, or solar, cells is made using a harmful and expensive chemical called cadmium chloride. Now a team has found a new, cheaper, safer way of making solar cells by replacing the toxic element in the process with a material found in bath salts, magnesium chloride, and these are just as efficient. Professor Ken Durose from Liverpool University explains how it could reduce the cost of solar energy.New Species How easy is it to find a new species for science? Whilst in the Bornean jungle, Dr Tim Cockerill discovered that it was relatively easy - one fell in his cup of tea! It was a tiny parasitic wasp. Another new species, of the same type of parasitic wasp, was recently discovered in a school playground in the UK. So new insects seem to be quite easy to find, but what about a new mammal or bird? Tim reveals that finding the creature is just the start of a lot of work needed to get his finding published and accepted.Fijian Fisherwomen More and more conservationists are turning to local knowledge to work out the best way to save ecosystems. A great illustration of this grass-roots approach is underway in Fiji. They use a traditional system where villages will close an area of fishing grounds for a few months for fish stocks to recover. Conservationists are now learning about this system, known as 'tambu', to see if it can be used on a longer-term basis to help give fish stocks, that have become seriously depleted in the last few decades, a chance to recover.Physics questions University College London cosmologist, Andrew Pontzen answers questions sent in by listeners about why, given the immense heat at the Big Bang, is there so much hydrogen in the universe, and not more of the larger atoms, which are forged under conditions of great heat? And are black holes responsible for the missing matter in the universe?Producer: Fiona Roberts.

Antarctic Invasion Antarctica is the most pristine place on Earth, having only been visited by humans in the last 200 years, and being tens of thousands of miles from the nearest land. But these days, around 40,000 tourists and hundreds of scientists visit the Antarctic every year, and with them come stowaways in the form of bugs, beetles and plants. As a result, the ice -free areas of the Antarctic are at severe risk of invasion. Is it too late to do anything about it?Longitude Prize: Water How can we ensure everyone can have access to safe and clean water? Water is becoming an increasingly scarce resource. 44 per cent of the world's population and 28 per cent of the world's agriculture are in regions where water is scarce. The challenge is to alleviate the growing pressure on the planet's fresh water by creating a cheap, environmentally sustainable desalination technology. London's Becton desalination plant is expensive to run, and so used for emergencies only. Marnie Chesterton meets some Danish chemists using membranes from nature which could help make salt water drinkable, without the energy requirement of current technology.Patents in science European Inventor Award winner Christofer Toumazou explains his invention - a USB microchip that reads a patient's DNA. He tells Adam Rutherford how the patent system has protected his ideas.Longitude Prize: Antibiotics Dame Sally Davies explains why, in an era of growing antibiotic resistance, it's important to have a cheap, easy-to-use test to identify bacteria. Muna Anjum from the Animal Health and Veterinary Laboratories Agency is working on identifying those resistance genes in certain bacteria. Paul Freemont's team at Imperial College is using synthetic biology to build a device that can detect specific bacteria - precisely the sort of work that might answer the Longitude Prize's challenge.Producer: Fiona Roberts.

The first ball kick of the opening ceremony of the 2014 World Cup is taken by a young paraplegic Brazilian, wearing a robotic exo-skeleton, controlled using his mind. Adam hears from Miguel Nicolelis, the neurophysiologist behind the high profile science stunt. Closer to home Sophie Morgan, paralysed for a decade, demonstrates her robot exo-skeleton, or REX, which allows her to walk and stand.This week, scientists at the University of Reading claim to have created a computer that has successfully duped humans into thinking it was a 13-year-old boy. This has been widely reported as the first computer to pass the Turing test, but is it? Is this a leap forward in artificial intelligence or a case of moving the goalposts. Anil Seth from the University of Sussex, gives us his opinion.Forget the Internet of things, welcome, the internet of vegetables. An EU-wide project has developed "cyborg plants" with in-built sensors. These allow the plant to "talk" to scientists, giving them updates on water and nitrogen levels. Koushik Maharatna from the University of Southampton explains the benefits of being able to talk to plants.We are surprisingly good at remembering songs we haven't heard for many years, but what is it about a song that makes it so memorable? Is there a perfect formula? Scientists hope that a new game will find out. A citizen science project plans to analyse thousands of results from the songs best remembered by the public. Adam Rutherford sings along and asks Dr Ashley Burgoyne, a computational musicologist from the University of Amsterdam, why some songs are more memorable than others.Producer: Fiona Hill.

Moving Mountains Removing the tops off mountains was common practice in the eastern United States to strip mine for coal. Critics have previously called for it to be banned because of the health risks. But in China, the same thing is now happening but on a much larger scale, all to create new land for people to live on. In a comment piece in this week's Nature journal, Chinese scientists call this unprecedented geo-engineering "folly", and liken the practice to "performing major surgery on Earth's crust". Dr Adam Rutherford talks to Dr Emily Bernhardt from Duke University in the US about the potential risks of the Chinese mountain moving.Alien Invader Species Inside Science bug man, Tim Cockerill, responds to headlines that alien killer snakes, capable of killing dogs, cats and even children, are on the loose in Britain. He goes to look for the supposedly terrifying reptiles, and finds out instead, about a colony of aesculapian snakes, whose biggest meal might be a rat. In search of more danger, he goes on to Sheerness in Kent, to hunt for the "alien" yellow-tailed scorpion. These arachnids don't prove much of a threat either, he discovers. As long as you keep your trousers tucked in your socks.Longitude Prize: Zero Carbon Flight If our use of air travel continues to rise at the current rate, by 2050, it'll make up 15 per cent of global warming from human activities. If the Longitude Prize topic chosen is flight, the challenge will be to design and build a zero or close-to-zero-carbon aeroplane that is capable of flying from London to Edinburgh, at comparable speed to today's aircraft. Marnie Chesterton speaks to physicist Helen Czerski and Professor Callum Thomas, from Manchester Metropolitan's Centre for Aviation, Transport and the Environment, about the possible options.Football Stickers "Got, Got, Got, Need!". With the football World Cup upon us, footy-mad kids barter to fill their world cup sticker books. Adam talks to mathematician Professor Yvan Velenik from the University of Geneva, about the myth that some stickers are rarer than others, and shares his statistical analysis about how many stickers you would need to buy, to fill the book.Producer: Fiona Hill.

Women of science London's Royal Society was buzzing last week as historians and scientists chewed over the lives of iconic women scientists. But at a time when far more women go into science, the percentage who make it to professor is still alarmingly low compared to men. Last week's Revealing Lives event by The Royal Society was also about learning lessons from history which are of benefit to women working in science today.Mapping the ocean floor We really do know less about the ocean floor on Earth than we do about the surface of Mars, Venus and the Moon. In the case of the Red Planet, the maps are about 250 times better. This gap in our home-planet knowledge has recently been highlighted by the search for the missing Malaysia airlines plane MH370. The suspected search area in a remote part of the Indian Ocean is so poorly mapped, it's not even clear how deep the deepest parts are. Ocean floor mapping can be done by ship board echo-sounders, bouncing sound waves off the sea floor. But this is very expensive. A new cheaper, quicker way is to use a satellite to measure fluctuations in the sea surface caused by gravitational perturbations caused by underwater topography.Longitude Challenge 2014 - Food security By 2050 there will be an estimated 9.1 billion people on the planet. In the face of limited resources and climate change, how can we feed the world with less? Michael Moseley thinks eating insects is a start whilst Marnie Chesterton checks out a field of self-fertilising crops. And the issue that it's not always the amount of food, but the right food is highlighted in a report from the Metropolitan Manila area of the Philippines where a portion of fries and a burger is cheaper than a kilo of carrots.Amplituhedron Particle physicists have discovered a mysterious jewel-like object that exists in higher dimensions in mathematical space. This multifaceted object, The Amplituhedron, greatly simplifies the complex calculations that explain what happens during particle collisions - the kind of collisions studied at particle accelerators, like the Large Hadron Collider. No one's entirely sure exactly what this object is, or how important it might turn out to be - there's some suggestion it may challenge the very notion that space-time is a fundamental property of our universe. Joel Werner caught up with the man who discovered this jewel, Nima Arkani-Hamed, at the Institute for Advanced Study in the United States to try and unravel exactly what this mysterious object is.Producer: Fiona Roberts.

Longitude Prize 2014 The Longitude Prize offers a £10 million prize pot to help find the solution to one of the greatest issues of our age. Votes from the British public will decide what that issue will be. This week, the six shortlisted challenges have been unveiled. They cover flight, food, antibiotics, paralysis, water and dementia. Alice Roberts talks to Adam about why we need an X-factor for science. Over the next month, Inside Science will profile each of these challenges and explain how you can cast your vote.Matter from Light In 12 months' time, researchers say they will be able to make matter from light. Three physicists were sitting in a tiny office at Imperial College London and while drinking coffee they found what they call a fairly simple way to prove a theory first suggested by scientists 80 years ago: to convert photons - i.e. particles of light - into electrons (particles of matter) and positrons (antimatter). Adam discusses the work with theoretical physicist Professor Steven Rose from Imperial College London and science writer Philip Ball.Longitude challenge - Dementia How can we help people with dementia to live independently for longer? Dr Kevin Fong is the champion for this Longitude Challenge, arguing that we all use technology to support our lifestyles but that people with dementia need extra tech. Marnie Chesterton visits Designability, a Bath-based design charity that works with people with dementia to develop new technologies. Their Day Clock shows that a simple design can produce radical results.Coastal deposition The destructive winter storms that hit the UK caused were flooded by the worst tidal surge on the east coast in 60 years. Sand dunes play an important defensive role on our coastline but little is known about their resilience or recovery rate. So after the December 5th storm, scientists sprang into action in Lincolnshire with a new project that officially began in February. The aim is to help future coastal management by researching the effects of storm surges on sand dunes.Producer: Fiona Roberts.

Melting Antarctic Ice Shelf Nothing can stop the collapse of the Antarctic Western Ice shelf. That’s according to NASA this week. Key glaciers in Antarctica are irreversibly retreating, and according to the scientists studying this region they’ve reached a state of irreversible retreat - the point of no return. Brain enhancing devices If given the option, would you think faster or increase your attention span? Neuroscientists now say that non-invasive brain stimulation using electrical currents could do just that. The technology is still fairly new but is now being sold by commercial companies often marketed to gamers suggesting that it could increase your attention and make you think faster. But do they actually work? Inside Science sent Melissa Hogenboom to Oxford try one out and to discuss the science behind the hype.Black holes How big can black holes get? A listener asks and Professor Andy Fabien, Director of the Institute of Astronomy at Cambridge University answers.Optical and atomic clocks At this week’s ‘Quantum Timing, Navigation and Sensing’ Showcase at the National Physical Laboratory, researchers are working on sensors that allow us to see through walls; super-accurate atomic clocks the size of matchboxes; and GPS trackers that can elude an enemy jamming the signal. We sent Inside Science reporter Tracey Logan to work on her time management.Bat jamming moth noises and other insects that go bump, chirrup, squeak in the night Inside Science’s resident entomologist, Dr. Tim Cockerill has been exploring a whole soundscape that’s hidden from our limited hearing range. Including, eavesdropping on a secret sonic arms race between echo-locating bats and bat-jamming acoustics created by the genitals of a hawkmoth.Producer: Fiona Roberts

Artificial DNA DNA is the molecule of life, conserved across all living species for 4 billion years. But now scientists have made a new, artificial version, by introducing two extra letters, not found in nature, into the genetic code of a common microbe. The E. coli bacteria are able to grow and replicate as normal despite these artificial additions. In future, this research might create organisms that can make new proteins, which could offer new drugs and vaccines. What is fire? A listener wrote in to ask about fire – what is it? And what is the difference between a super-hot gas and plasma? We went straight to Dr. Guillermo Rein, Mechanical Engineer at Imperial College and Editor-in-Chief of the journal Fire Technology. It turns out, they’re great questions and even the experts can’t quite agree on the answers.Obituary - Colin Pillinger British planetary scientist Professor Colin Pillinger, best known for his 2003 attempt to land a spacecraft on Mars, has died aged 70. .Oxford Maths Institute The new Maths Institute at Oxford University is named the Andrew Wiles Building, after the mathematician, who solved Fermat’s Last Theorem. The Institute includes some nods to other mathematical theories included in the design. From the never-ending Penrose paving at the entrance to lighting based on solving complex equations and mathematical illusions build into the construction. The architects hope the building will inspire the next generation of mathematicians.Carlos Frenk Professor Carlos Frenk, astronomer at Durham University has just joined the ranks of Steven Hawking, Edwin Hubble and Albert Einstein by winning the Royal Astronomical Society’s Gold Medal for Astronomy. Producer: Fiona Roberts

A recent paper demonstrated that mice show elevated stress levels in the presence of male hormones. What implications does this have for future mouse research? Adam Rutherford heads to University College London to speak to Dr Clare Stanford, who works with mice and men.How do you get jet fuel from thin air? Just add water, carbon dioxide and a large amount of concentrated sunlight. A team from the European Solar Jet Project has, for the first time, proved that you can make 'green' or carbon neutral paraffin, the hydrocarbon used in jet fuel. It's feasible; the next step is to try and make this process commercially viable.Neuroscience is a fast growing and popular field, so naturally there are an abundance of stories reported in the press often illustrated with a beautiful picture of the brain. But despite the advances, when an area of the brain 'lights up" it does not tell us as much as we'd like about the inner workings of the mind. Adam Rutherford speaks to neuroscientists to get to the bottom of what brain imaging can be useful for and when over-interpretation is an issue.Our resident zoologist Dr Tim Cockerill recently found himself filming animals deep in the jungles of Borneo. Before he left, we gave him an audio recorder to see what he could discover about the animal communities there, just by listening to them. It seems you can set your watch by some of their calls.Producer: Marnie Chesterton.

Y Chromosome We learn from a young age that if a fertilised egg carries XX chromosomes it will be a girl, but with XY it will be a boy. This male Y sex chromosome has lost many genes along its evolution over the past 180 million years and now only about 20 genes remain. Now two new studies in Nature journal have given clues into how the Y chromosome evolved into its current state by looking at the genetic make up of 15 species the team built an archaeological record of all the mutations that occurred over time - to trace the timing of how the Y originated.... Professor Henrik Kaessmann from the University of Lausanne in Switzerland explains that the genes that remain play a more important role than previously believed.Everest Avalanche Last week the biggest single loss-of-life event occurred on Everest: a huge avalanche killed 16 Sherpa guides. All were so-called "icefall doctors", possibly the riskiest job of all, which involves finding a route through the broken mass of icefall, and then securing ladders and ropes for mountaineer tourists to follow. The Himalayan Sherpas have abandoned the climbing season out of respect for the fallen. There are many questions about health and safety, but we want to know what could be done to help? BBC Science Reporter Victoria Gill has been looking at the science behind avalanches, Are avalanches predictable? And will global warming in the Himalayan region make them more common? Aphid Survey This month the Rothamsted Research in Hertfordshire's Insect Survey will have been monitoring national aphid populations for fifty years. Aphids, such as greenfly and blackfly, can cause extensive damage to plants and crops. The aphid season - as many gardeners will know - is just about to start. But how has the recent mild, wet winter affected their numbers?Lichens An Inside Science listener emailed in to ask about lichens - what are they and how do they live. We called in plant ecologist Professor Howard Griffiths, at the University of Cambridge to fill us in on these hardy, pioneering organisms.Longitude 300 years ago there was no way of knowing the position of a ship out on the high seas. The greatest scientific challenge of the age was navigation. Britain's response was to offer a large prize fund for the solution to the problem of Longitude. Richard Dunn, curator and head of science and technology at Royal Museums Greenwich tells Marnie Chesterton the story of John Harrison, a clockmaker and carpenter, who solved this seemingly impossible problem.Producer: Fiona Roberts.

How sperm recognises the egg The discovery of a protein on mammalian sperm almost a decade ago, sparked the search for the corresponding receptor on the egg. Now researchers in the UK have found this receptor in mouse egg cells. They propose to call it Juno, after the Roman Goddess of fertility and marriage. The finding indicates that these two proteins need to interact for normal fertilisation to occur. And in humans, it could lead to early screening of couple to decide which appropriate fertility treatment they require.Dogs as clinical models Dogs play an important companion role in society, but man's best friend can suffer from hundreds of different diseases. Surprisingly, many of these are very similar to human diseases, including cancer and autoimmune conditions. Research into a range of naturally occurring canine conditions has the potential to lead to some ground-breaking medical advances and improve human health.Automatic Facebook Keeping up with your online social network of 'friends' on Facebook can sometimes be time consuming and arduous. Now artificial intelligence expert, Boris Galitsky, has invented a robot to do the bulk of his social interactions online. But how realistic is it? And does it fool his cyber pals?Artistic brains feedback Last week we ran an item showing that researchers have found that artists' brains were structurally different from those of non-artists. This sparked a lot of listener feedback and debate on what is the difference between being an artist and being creative? Is it nature or nurture, or both? We attempt to get your points across!Invasive Alien Species The European Parliament has approved new legislation which hopes to contain the spread of invasive species of plants and animals in Europe. It has proposed bans on the possession, transport, selling or growing of restricted species. The list, which includes plants like Japanese knotweed and Himalayan balsam and animals like the "killer" shrimp, which can wreak havoc when they spread, was restricted to just 50 species. But now it will be open-ended, so when new alien invasive species arise, they can be dealt with more easily. But in the UK, what constitutes an 'alien' species and how do you decide whether it's invasive? And what about all the 'alien' plants we already grow in our gardens?Producer: Fiona Roberts.

Whaling The International Court of Justice in the Hague recently ruled that Japan should stop whaling in the Antarctic “for scientific purposes.” They found that the primary purpose of the science programme, JARPAII, was not science. In that case, what was it for? Inside Science puts that question to whale biologist Vassili Papastavrou, and Lars Walløe, Japan’s expert witness at the ICJ.LUX Experiment to detect dark matter Scientists are entering a critical phase in the quest to find the one of most mysterious particles in the Universe. An experiment called LUX, in South Dakota is about to be switched on that offers the best hope yet of detecting dark matter - a substance thought to make up a quarter of the Universe, yet one that nobody has ever seen. Falling in the elderly As we age, we tend to fall more and the repercussions of falling are more serious But why? Even if you rule out physical reasons for why you might be more likely to fall, older people still fall more often. Professor Raymond Reynolds, at the University of Birmingham, thinks it might be something happening in their heads – the balance system could be letting them down. Tracey Logan climbs aboard the shake shack to find out.Arty Brains Artists often have lifestyle that requires complete immersion into their world, now a team finds that this difference is reflected in their brains too, that is, their brains are structurally different to non-artists. Participants' brain scans revealed that artists had increased grey matter in areas relating to fine motor movements and visual imagery. Our reporter Melissa Hogenboom speaks to artists and the authors of the new research to find out what exactly is different about their brains. The study is published in NeuroImage. Producer: Fiona Roberts

Calorie restriction Careful restriction of the number of calories eaten, without causing malnutrition, extends the lifespan of numerous organisms – from worms to mice – but whether it works in monkeys is controversial. Building on results from a long-running primate experiment, a team at the University of Wisconsin show a reduction in mortality, in response to caloric restriction. So there seem to be some benefits, but Tracey Logan asks if this can be applied to humans? And would we want to live longer on a tightly controlled diet?Dating the Moon New work by planetary scientists from France, Germany and the USA, has given the most accurate date yet for the birth of the moon. The Moon is believed to have formed out of debris from a massive collision with another Mars-sized planet. The date of this event has always been controversial as radioactive decay readings have produced wildly different results. But this clock uses a different approach, and rules out an early-forming moon. The later the moon formed, the less time for life to evolve.Mars Yard In 2016 Europe launches a mission to mars. ESA’s robotic rover will land on Mars in 2019, and in the meantime, needs to practice. To test it, scientists have recreated the surface of Mars, with 300 tonnes of sand. Reporter Sue Nelson went to Stevenage to play in the sandpit, for science.IPCC This week sees the most recent report from The Intergovernmental Panel on Climate Change, the IPCC. And the message is the same: the climate is changing as we continue to add greenhouse gases to the atmosphere. Should we concentrate on adapting to climate change, rather than stopping it? Professor of Coastal Engineering at Southampton University, Robert Nicholls and Dr Rachel Warren of the UEA’s Tyndall Centre for Climate Change Research discuss adaptation plans.Producer: Fiona Roberts

School Report on Fracking This week, Inside Science is taken over by BBC School Reporters and Melissa Hogenboom eavesdrops on a school in Lancashire, preparing their report on fracking. They discuss the issues very local to them, as well as the wider international angles and how best to present the story.Purple GM tomatoes The chemical that gives blackberries, blackcurrants, blueberries and some red grape varieties their distinctive purple colour is Anthocyanin. It’s been shown to have some possible anti-cancer properties as well as some protection against cardiovascular disease. So scientists at the John Innes Centre have inserted the ‘purple gene’ into tomatoes to try and boost their health-giving properties. This step is relatively easy, compared to navigating the rules and regulations of getting to the stage of producing purple ketchup. Gareth Mitchell asks the School reporters what they think about Genetic Modification of food crops.Artificial humans With progress in 3D printing of organs, brain-machine interfaces and even artificial skin. Materials scientist at University College London, Professor Mark Miodownik, thinks that the future really could be bionic. Would the School Reporters want to become half human, half machine? And would these technological advances just be used for repairing people who have been injured or really need it, or will it mean that those with enough money could enhance themselves to superhuman states? Shark Attacks Potentially dangerous sharks are being culled off the coast of Western Australia. The government claim it’s as a result of a rise in the number of deaths by shark attack. Many people are outraged by the killings. Shark attacks are still really rare compared to car accidents or even deaths from bee stings – so do the School Reporters think this is a good idea? Or do they think listening to what the scientists studying shark behaviour and developing shark deterrents say, is a better way to go?

Cosmic Inflation and Gravity waves Scientists in the BICEP 2 Group say they've found the earliest rumbles of the Big Bang. Theory predicts how the universe first expanded. Now we have the first observation of the phenomenon behind it. The universe was kick-started by a so called 'inflation' - vigorous growth within a fraction of a second of the Big Bang going bang. To confirm inflation you need to detect ripples in the fabric of space called gravitational waves. And to find those, you need to look for twists and kinks in this stuff. The BICEP 2 radio telescope, at the South Pole, has been measuring the direction of twists of light from the Cosmic Microwave Background Radiation - which is a form of primordial light, a remnant of the Big Bang. The signals have been released that show distortions in that light that can only have been caused by gravitational waves. They could only be there if there was inflation. In other words, these observations have shored up one of the most important theories in cosmology. Gareth Mitchell discusses what this means with BBC Science Correspondent Jonathan Amos and Astronomer at UCL Dr. Hiranya Peiris.Photonic Radar As the search closes in on missing Malaysia Airlines flight MH 370, radar technology has been in the spotlight. At the same time, new research published in this week's Nature journal reports on field trials of the next generation of radars - photonics based. Lead-author Paolo Ghelfi, from the National Laboratory of Photonics networks in Pisa, Italy explains their methods. Professor David Stupples, a radar expert from City University, London, explain that this cheaper, more accurate technology could end up in your car.Show Us Your Instrument - Infrared camera Infrared cameras detect heat, and process this as a colourful image. Dominic McCafferty, from Glasgow University, uses this kit to study stress levels in birds. When an animal is stressed, blood is drawn away from its skin and routed to the essential organs. This 'fight or flight' reflex means the temperature of certain parts of the animal drops. The infrared camera measures this, providing a non-invasive way of testing an animal's stress level. Current projects include one to test chickens, aiming to improve their welfare.Water research When listener Dave Conway emailed in to ask about what research is being done on water, if any - we went straight to materials scientist Professor Mark Miodownik at UCL to find out.Taxidermy Is taxidermy a dying art? Not for the chattering classes of New York apparently. There's been a rise in demand for people to attend classes where they learn to stuff and mount animals, and often dress them up in costumes. But what is the value of the stuffed animals in museums? In the multimedia age of interactive displays, 3D printing and computer models - do we still need the stuffed and stitched creatures in glass cases?Producer: Fiona Roberts.

Are black boxes outdated technology? With GPS widely available in everyday gadgets like mobile phones, how could Malaysia Airlines Flight MH370 just disappear? Adam Rutherford speaks to Dr Matt Greaves, a Lecturer in Accident Investigation at Cranfield University, about how we track aircraft.Earlier this year, a new study from Japan announced a curiously easy way to make stem cells, by placing them in a mild acid bath. It seemed too good to be true, and according to recent critics, it is. One of the authors has declared that the paper should be withdrawn, that he has 'lost faith in it'.Ivan Oransky runs the site RetractionWatch, dedicated to scrutinizing irregular research. He talks to Adam about the value of post-publication peer review, and public scrutiny of science on the internet.A 30,000 year old killer, buried 100 feet under the Siberian permafrost, has risen from the dead. It's a mega virus, with the largest genome of any known virus, and, happily, only infects amoebae. Virologist Professor Jonathan Ball, of the University of Nottingham, explains the implications of reanimating dead viruses.And actual spaceman, retired NASA pilot Captain Jon McBride, came into the studio to share his out-of-this-world memories and prediction that the next generation of astronauts will be chosen on brains not brawn.Producer: Fiona Roberts.

Chemical weapons Disposing of Syria's chemical weapons is a difficult task, both politically and technically. The Organisation for the Prohibition of Chemical Weapons (OPCW), responsible for the decommissioning, has kitted out a special ship, the MV Cape Ray to hydrolyse "priority" toxic substances. Hamish de Bretton Gordon, a chemical weapons expert from SecureBio, explains why destroying chemical precursors on dry land is not an option and whether the job will be done on time.Tracking turtles Satellite tags have finally given researchers insight into the "lost years" of loggerhead turtles. After many failed attempts, researchers have worked out how to attach the tiny tags to the months-old animals during the uncertain period when they leave US coastal waters and head out into the Atlantic Ocean. The data suggests the loggerheads can spend some time living in amongst floating mats of Sargassum seaweed, in the Sargasso Sea.Technology for Nature The tools and gadgets available to remotely track animals and monitor populations and their habitats are getting better and more mechanised. Cameras mounted on birds can record where they fly; audio recordings capture bat calls; satellite images monitoring habitat change. However all this digital data needs to be analysed. Professor Kate Jones, an expert on biodiversity at University College London, thinks that this is where more technological advances are needed. She wants image recognition programmes to scan through millions of remote camera images, or sound recognition of hundreds of thousands of bat calls to be developed.Climate The recent extreme rainfall has left many asking, is this weather linked to climate change? A new project 'weather@home' 2014, aims to use a large citizen science experiment to answer this question. Myles Allen, Professor of Geosystems Science at the School of Geography and the Environment, and Dr Nathalie Schaller, both of Oxford University, explain that they aim to run two sets of weather simulations. One will represent conditions and "possible weather" in the winter 2014, and the second will represent the weather in a "world that might have been" if human behaviour had not changed the composition of the atmosphere through greenhouse gas emissions. By comparing the numbers of extreme rainfall events in the two ensembles, 'Weather@Home' will work out if the risk of a wet winter has increased, decreased or been unaffected by human influence on climate.Producer: Fiona Roberts.

Neuroscientist Miguel Nicolelis is one of the world's leading researchers into using the mind to control machines. He is involved in the "Walk Again Project" which aims to build a suit that a paraplegic person can wear and control so that he or she can kick a football at the opening ceremony of the 2014 World Cup in Brazil. Adam is joined by biomedical engineer, Professor Christopher James from Warwick University, who puts the field of Brain Machine Interfaces in context.Work published last week by Professor Ziv Williams looks at the possibility of rewiring the body. Paralysis is normally confined to spinal cord damage, not the limbs themselves. Ziv Williams' work aims to use implanted chips to bypass the injury and have the individual control their own paralysed arms.Listeners ask if there is a gene for fundamentalist intolerance. We put the question to Professor Tim Spector, author of Identically Different.Adam Rutherford heads down to the psychology department at London's South Bank University... for a pint. Dr Tony Moss has built a fake pub, complete with lighting, music and even a fruit machine, to make drinkers feel that they are in a real bar. He says the venue treads a middle ground between a sterile lab, and an actual pub, where there are too many variables to reliably study behaviour.Professor John Shepherd from Cardiff studies alcohol and behaviour from the other end - the drunken nights out that end up in A&E. A few simple initiatives have helped reduce violence levels by 40%Producer: Fiona Roberts.

Bees - Nearly all bees in the UK suffering serious declines. They're mostly threatened by habitat and land-use change. But disease also plays a part. Adam Rutherford talks to Professor Mark Brown about new work he's done looking at the evidence of diseases harboured by honeybees, spilling over into wild bumblebees.Pain and epigenetics - Marnie Chesterton goes to Kings College, London to watch identical twins being tested for pain tolerance. The study is to gain insight into the genetic components of pain perception. One area which is fascinating researchers like Professor Tim Spector is the role of epigenetics in how we process pain. Our epigenome is a system that changes the way our DNA is interpreted. Genes can be dialled up or down, like a dimmer switch, by adding little chemical tags to the DNA. These chemical tags, unlike DNA, are changeable, in response to the changing environment. So could the way we live affect the pain we feel?Whales from Space - More listeners' questions, this time, asking whether surveys using images from satellites to see whales underwater, could be hijacked by whale hunters? Peter Fretwell from the British Antarctic Survey has the answer.Genetics of sexual preference - The media is all of a twitter this week over unpublished work recently revealed on research looking for genes related to homosexuality. We hear from Professor Tim Spector on the topic, and Adam talks to Professor Steve Jones about the science.Producer: Fiona Roberts.

Whales from Space. Scientists have demonstrated how new satellite technology can be used to count whales, and ultimately estimate their population size. Using Very High Resolution (VHR) satellite imagery, alongside image processing software, they were able to automatically detect and count whales breeding in part of the Golfo Nuevo, Peninsula Valdes in Argentina.The new method could revolutionise how whale population size is estimated. Marine mammals are extremely difficult to count on a large scale and traditional methods are costly, inaccurate and dangerous; several whales researchers have died in light aircraft accidents. How long will the floods last? Is this a trend caused by climate change? Should I turn on the kitchen taps so that house is at least flooded with clean water? We put listeners' flood questions to experts from the Centre of Ecology and Hydrology and the British Geological Survey.The instrument we're shown this week is from JET (Joint European Torus) in Culham,. It's the world's largest 'tokamak' - a type of nuclear fusion reactor. The hope is that in a few decades it could be supplying much of the world's electricity. It works by fusing nuclei of hydrogen together to produce helium and a lot of excess energy. It's the power source of the Universe, as all stars run on fusion energy. But on Earth we have to go to much more extreme conditions to achieve it. Upwards of 100 million degrees Celsius, which is around ten times hotter than the Sun. Joanne Flannagan, shows us her lasers which measure the hot fusion plasma inside JET.CERN wants a new tunnel. The 27km long, Large Hadron Collider in Geneva found evidence of the Higgs boson recently. But if we want to know more about this elusive particle and others that make up our universe, the physicists say they're going to have to go bigger. With a 100km long tunnel, in fact. Talks are afoot as to where and how they will build it. But Lucie asks reporter Roland Pease whether it'll be worth it?The current Discoveries exhibition at Two Temple Place, on the banks of the Thames, brings together treasures from eight University of Cambridge museums, in a beautiful period building, built by Waldorf Astor. The show combines objects from science and arts collections to explore the theme of 'Discoveries'. Curator Professor Nick Thomas gives Lucie Green a tour.Producer: Fiona Roberts.

The warning that floods are likely to become more common, or more severe, won't be a high priority for those with homes currently deluged. But it is something architects, engineers and planners have been taking very seriously. Dr. Adam Rutherford finds out about some of the innovations, both in UK and abroad, being designed for homes in areas prone to flooding - from simple door guards and waterproofing which can be retrofitted to existing houses - to entire city re-landscaping, or 'waterscaping' which aims to make room for the river, rather than fighting against it.Last week Adam talked about research showing that most people of European or East Asian descent carry a small percentage of Neanderthal DNA - about 2%. He examined some of the physical characteristics we may have got from the genes of our ancient cousins. This week Inside Science addresses some of the questions this fascinating work prompted.A new study in the journal Neuron this week, looks at what happens in the brain when one of the senses is dulled. Dr. Patrick Kanold, from the University of Maryland in the States, and his colleagues simulated blindness in mice by keeping them in the dark for a week, to see what happened to the parts of their brains involved in hearing. The found that the mouse's hearing improved. We sometimes talk about the brain being 'hardwired': all the neurons locked in place from early childhood. It was assumed that there was only a short, finite period when the brain was still capable of changing, but the new research shows parts of the brain still has room to manoeuvre.A recurring problem in science is that we are far better at collecting vast amounts of scientific data than we are at actually analysing them. To combat this problem, the charity Cancer Research UK have just launched a mobile phone game, 'Genes In Space', that farms statistical analysis out to the masses. Under the guise of flying a spaceship through a meteor storm, game players actually navigate their way through genetic sequence data from breast cancer patients. The information on the virtual path they take is automatically uploaded to the database and fed back into the scientific process.Producer: Fiona Roberts.

We now know that Neanderthals and our ancestors interbred over 40,000 years ago. Recent research has shown that most people of European or East Asian descent carry a small percentage of Neanderthal DNA - about 2%. But two new papers this week examine some of the physical characteristics we may have got from the genes of our ancient cousins. They include some disease susceptibilities and hair and skin characteristics, which may have helped our forebears survive in northern climes.There have been many sensationalist headlines in the news this week suggesting that the deadly bubonic plague could return, when really, it never went away. And while it can still be deadly, it can be treated early with antibiotics. In the Middle Ages the Black Death is thought to have killed up to half of the European population and so too did the Justinian Plague 800 years earlier. Now scientists have compared these two plague genomes to find that they were both caused by distinct strains of the same bacterium, Yersinia Pestis. Knowing how the pathogen evolved in the past is crucial to our understanding of possible future strains of plague. Lead author Dr David Wagner from the University of Arizona tells Dr Adam Rutherford that it's very unlikely the plague will return on a mass scale.It's a windy Show Us Your Instrument this week - Prof Konstantinos ('Kostas') Kontis, Professor of Aerospace Engineering shows us around his wind tunnel. It's used to help develop more effective plane wings, helicopter rotors, and wind turbine blades, but cyclist Sir Chris Hoy has also been a test sample. Glasgow University is currently building a hypersonic wind tunnel, which can test air flow at speeds of up to Mach 10.We all unconsciously synchronise our movements and researchers at the University of Birmingham have shown how professional musicians make tiny adjustments in their playing to keep time with their colleagues. Alan Wing, Professor of Human Movement in Psychology tells Adam how this research about minute synchronisation is helping to inform how robots can be designed to interact with humans.Stem cells can become any other cell in the body from nerve to bone to skin, and they are touted as the future of medicine. Embryos are one, often ethically charged, source of stem cells and in 2006 Nobel prize winning research showed that skin cells could be "genetically reprogrammed" to become stem cells. These were called induced pluripotent stem cells. Scientists in Japan have now shown, in mice, that this previous painstaking method of making the versatile cells can be replaced by little more than a short dip in acid. Professor Chris Mason from University College London tells Adam that this major breakthrough could be faster, cheaper and possibly safer than other cell reprogramming technologies.Producer: Fiona Hill.

The Higgs boson has been discovered, providing the final piece of the jigsaw puzzle for the Standard Model of particle physics, a description of how the universe works. But what physicists haven't found yet, which they should have, are supersymmetry or SUSY particles. Roland Pease attended a recent meeting of top physicists, and shares with Adam Rutherford the latest discussions about where to look next.The history of neutrinos is littered with interesting characters. It was Wolfgang Pauli who first suggested their existence. Pauli was so unsettled by his proposal that he bet a case of champagne against anyone being able to discover these "pathologically shy" particles. Since then, scientists have built ever more elaborate experiments to try and detect these particles. Ray Jayawardhana, Professor of Astrophysics and author of a new book "The Neutrino Hunters" explains more about the most abundant particle in the universe.This week's Show Us Your Instrument is a tool used to help scientists measure the glaciers in the Antarctic. Julian Dowdeswell, a glaciologist from the University of Cambridge, uses an echo-locator to look at the dynamics of large ice masses and their response to climate change.Fungi, not viewed favourably by gardeners, can be good for rainforest biodiversity. Dr Owen Lewis from Oxford University tells Melissa Hogenboom that plots sprayed with fungicide soon become dominated by a few species at the expense of many others, leading to a marked drop in diversity.A mysterious illness killing dogs has been in the headlines this week. David Walker a veterinary specialist, says that although it's not clear what's causing the disease, people should not panic.

For a couple of hundred quid, one of many companies will send you a kit for sampling your own genome, and most will tell you your genetic risk for some diseases. In December the US Food and Drug Administration imposed a ban on one of these companies, 23andme. The reasoning was that if the organisation is offering medical advice, it needs to be medically regulated. Geneticist Professor Robert Green from Harvard Medical School argues that people can cope responsibly with their genetic information and that the FDA is being over-cautious.Most people are familiar with recurrent infections caused by bacteria such as tonsillitis and bladder infections, where you pick up an infection, get treated with antibiotics and then after a few weeks or months the infection reappears and you need another course of antibiotics; this is a problem that can go on for many years, and is a major healthcare burden world-wide. Marnie Chesterton met a team from Imperial College studying the elusive persister cells responsible for these relapses.Earthquakes usually occur in subduction zones, where one tectonic plate plunges beneath another. Now a team at University of Aberdeen has analysed a large earthquake database and developed a global map giving clues to which areas could be capable of causing giant earthquakes. Professor Nicholas Rawlinson explains the difficulties of predicting.The venom of scorpions contains neurotoxins, which attack the nervous system of animals - it's one of the reasons why it's not a good idea to be stung by a scorpion. The structure of these toxins very closely resembles the structure of a group of proteins with a completely different purpose, called defensins. Professor Jan Tytgat from KU Leauven suggests that venom evolved from these defensins.

Scientists following in the footsteps of Edwardian explorer, Douglas Mawson, have been trapped in pack ice in the Antarctic. The Chinese vessel that came to their rescue also became "beset" in the ice. The BBC's Andrew Luck Baker talks to Adam Rutherford about the catacylsmic event that caused multi-year ice to break away and trap the Academik Shokalskiy and Professor John Turner of the British Antarctic Survey underlines the importance of differentiating between extreme weather events and the impact of climate change.A team at Rothamsted Research in Hertfordshire has succeeded in genetically engineering plant seeds to contain the Omega-3 oil usually found in oily fish. Seeds from Camelina sativa (false flax) plants were modified using genes from microalgae - the primary organisms that produce these beneficial fatty acids.The oil has now been incorporated into salmon feed to assess whether it's a viable alternative to wild fish oil. Dr Johnathan Napier tells Melissa Hogenboom that he hopes the plants will provide a sustainable source of long chain polyunsaturated fatty acids.From fossils we know an awful lot about the animals that walked on the Earth, swam in the sea and flew in the air. But fossils have never been good at revealing the colour of these animals. With increasingly sophisticated sampling techniques however, scientists are starting to get a much better, technicolour glimpse into these extinct fauna. And it turns out that colour played a much more important role than just camouflage and decoration. Johan Lindgren form Lund University in Sweden has been finding out how the pigment, melanin, allowed ancient marine reptiles to travel all over the oceanic globe.Show Us Your Instrument: Dr Andrew Polaszek, Head of Terrestrial Invertebrates at the Natural History Museum reveals his compound microscope (with Nomarski Differential Interference Contrast) which he uses to discover "hidden biodiversity", particularly in parasitoid wasps.Stephen Hawking threw a party for time travellers and issued the invitation after the event. Astrophysicists after a long poker game decided to use Twitter instead, to flush out the time travellers in our midst. Professor Robert Nemiroff from Michigan Tech University and his students mined social media for references to the Comet ISON and the naming of the new Pope Francis, before both those events had actually happened. Producer: Fiona Hill.

The ancient inhabitants of Britain; when did they get here? Who were they? And how do we know? Alice Roberts meets some of the AHOB team, who have been literally digging for answers.The Natural History Museum's Chris Stringer, is the Director of AHOB, the Ancient Human Occupation of Britain, a project which, over the past 12 years, has brought together a large team of palaeontologists, archaeologists, geologists and geographers, to pool their expertise in order to unpick British History.Nick Ashton from the British Museum has been in charge of the north Norfolk site of Happisburgh, where the crumbling coast line has revealed the oldest examples of human life in Britain, 400,000 years earlier than previous findings of human habitation, in Boxgrove in Sussex.The ancient landscape had its share of exotic animals. Hippos have been dug up from Trafalgar Square, mammoths have been excavated from Fleet Street. Professor Danielle Schreve is an expert in ancient mammal fossils, and tells us what these bones reveal about the ancient climate. Less glamorous than the big fossils, the humble vole is so useful and accurate as a dating tool that it has been nicknamed "the Vole Clock."Carbon dating has improved vastly in the past few years. Rob Dinnis, from Edinburgh University, explains why the AHOB team has been returning to old collections and redating them.

Professor Alice Roberts talks bacteriophages: viruses that infect the bacteria that infect us. With the rise of antibiotic resistance they are a potential weapon against infection.We hear from Paul Hebert, the biologist behind the International Barcode of Life project – a global effort to classify the entire world’s species according to their DNA. Bristol researchers have discovered that it is more than scent and colour that draws a bee to a flower – there is also an electric field.Claire Turner from the Open University shows us the instrument she uses to detect disease. It can sense when a heart transplant patient is rejecting their new organ, purely through monitoring their breath.

Antibacterial soaps and body washes make up an industry worth millions of pounds, but in the USA, producers have been told that they have just over a year to prove their products are safe, or, re-label or reformulate them. Many believe that using antimicrobial soaps, which often include the chemicals triclosan or triclocarban, keeps you clean and reduces the chance of getting ill or passing on germs to others. But the Food and Drug Administration in the USA says it's the job of manufacturers to demonstrate the benefits, to balance any potential risks. Professor Jodi Lindsay, expert in microbial pathogenesis from St Georges, University of London, tells Dr Adam Rutherford where this leaves British and European consumers.The world's most powerful satellite camera was launched today into space. Its mission, to map the billion stars in our galaxy. Professor Gerry Gilmore, Principal Investigator for GAIA, tells Inside Science about the planned "walk through the Milky Way" and BBC Science Correspondent, Jonathan Amos, spells out how GAIA could help detect future asteroids, like the one that wiped out the dinosaurs on earth.Just after the Second World War in a site in North Yorkshire, the discovery of a flint blade triggered the discovery of one of the world's most important Mesolithic or Stone Age sites. What makes Star Carr so special is that organic artefacts, bone harpoons, deer headdresses and even homesteads, were preserved in the peat 11000 years ago. But these precious artefacts are in trouble. Changing acidic conditions are turning the Mesolithic remains to jelly. Sue Nelson reports from the Vale of Pickering on how archaeologists are working with chemists to try to pinpoint exactly why the Stone Age remains are deteriorating so quickly.And Professor Chris Turney talks to Adam from his research ship in Commonwealth Bay in the Antarctic, where he is leading a team of scientists to recreate the journey made by Douglas Mawson, 100 years ago, on the Australasian Antarctic Expedition.Producer: Fiona Hill.

Food crime is now big business that criss crosses national boundaries, according to today's report into the safety and authenticity of our food. Public Analyst, Dr Duncan Campbell tells Dr Adam Rutherford that he and his colleagues are hampered by lack of funding and the lack of a national plan for a sustainable laboratory infrastructure. While report author, Professor Chris Elliott, the director of the Global Institute for Food Security at Queen's University, Belfast describes how he wants the UK's scientific infrastructure to be strengthened to avoid yet another serious food scandal.Show Us Your Instrument: Cosmic Scientist Dr Natalie Starkey from the School of Planetary and Space Sciences at the Open University reveals the NanoSims instrument.Thousands of miles apart the same species of microbes seem to crop up deep beneath the earth's surface in cracks of hard rock. Yet nobody seems to quite know how they spread so widely. Scientists now believe they may have survived completely isolated from the surface for what could be billions of years. Dr Matt Shrenk from Michigan State University explains that the biosphere as we know it is far more extensive than we previously thought.Crystallography... as it sounds is the study of crystals, but it's not quite as simple as that. It underpins many scientific fields and yet it remains a relatively unknown subject area. Scores of Nobel prizes have been won, the first almost 100 years ago and we wouldn't understand the structure of DNA without it. The United Nations has declared 2014 as the International Year of Crystallography and emeritus Professor Mike Glazer from Oxford University says he hopes it will help bring the subject out of the shadows.Producer: Fiona Hill.

Badger culls in England have ended and Professor Roland Kao from the University of Glasgow discusses with Dr Adam Rutherford the scientific options remaining to tackle the spread of bovine tuberculosis. Field trials of the TB cattle vaccine are due to start next year and Professor Kao hopes that their success in sequencing the genome of Mycobactrium bovis will also provide a greater understanding about how this devastating disease spreads. The name of Douglas Mawson isn't discussed along with the famous triumvirate, Scott, Amundsen and Shackleton, but one hundred years ago, he led the first science-only Australasian Antarctic Expedition. A century later, Professor Chris Turney is co-leading a repeat expedition, where scientists will repeat many of the measurements of the Mawson trip.Rising inflexion at the end of your sentences is known as "uptalk" or "valleygirl speak" and it's usually associated with young Californian females. But now a new study shows that uptalk is expanding to men. Professor Amalia Arvaniti explains that uptalk has negative connotations which makes men less likely to admit to using it, but it was clear was that this pattern of speech is like totally spreading.Waste plastic makes its way into many areas of the environment which can threaten wildlife. Small particles of plastic can also be ingested by organisms and as they act almost like sponges the plastics attract other chemicals onto their surface. Despite this their hazard ranking is the same as scraps of food or grass clippings. Dr Mark Browne from the National Centre for Ecological Analysis and Synthesis, USA, describes his new research in the journal, Current Biology, which shows that these microplastics have toxic concentrations of pollutants in which can harm biodiversity. He also explains how these microplastics transfer toxic pollutants and chemicals into the guts of lugworms. These worms have been nicknamed "eco-engineers" because they eat organic matter from the sediment and prevent the build-up of silt.Producer: Fiona Hill.

Therapeutic hypothermia is standard treatment for cardiac arrest patients to protect against the damaging or deadly repercussions of a beatless heart. But this global practice has been called into question after research in the New England Journal of Medicine reported no difference in survival rates between patients chilled to 33 degrees and those cooled to just below normal body temperature to 36 degrees. Dr Jerry Nolan, vice chair of the European Resuscitation Council tells Dr Adam Rutherford how doctors worldwide are reacting to this new study and Dr Kevin Fong, author of "Extremes, Life, Death and the Limits of the Human Body" describes how medicine has historically harnessed hypothermic states to heal.Show Us Your Instrument: The European Space Agency's GAIA mission is due to launch just before Christmas. It will spend the next 5 years recording space, using a billion pixel camera. This camera is made up of charge-couple devices, similar to the ones you'd find in your smart phone. These are damaged by space radiation. Dr Ross Burgon damages them in his lab first, to tell whether the images coming back from space are real stars or planets, or the digital equivalent of a smudge on the lens.Methane is the second most important greenhouse gas after carbon dioxide because it's 25 times more powerful than carbon dioxide at trapping the sun's rays. And it doesn't hang around as long either, ten years as opposed to a 100. So tackling methane is seen by many countries as a useful way of reducing greenhouse gases, quickly. But that depends on knowing how much there is. A new paper in the Proceedings of the National Academy of Sciences reveals that United States could be underestimating its methane emissions by as much as fifty per cent. Dr Vincent Gauci Head of Ecosystems and Biodiversity at the Open University explains how the Americans got their sums so wrong, and considers whether the British calculations are similarly suspect.The fuzzy concept of "terroir" for wine fans has always been difficult to pin down. Climate, soil, geology and individual wine-making practice don't make it easy to identify what makes particular wines unique. But Dr David Mills, Professor in the Department of Viticulture and Enology at University of California, Davis, has used DNA sequencing to study the microbial ecology of individual grapes. And he concludes bacteria and fungi could explain "microbial terroir".Producer: Fiona Hill.

Every twenty years there's a detailed survey of the birds of the UK and Ireland and today, the 2007-2011 Bird Atlas is published. Adam Rutherford hears from Dawn Balmer from the British Trust for Ornithology about the citizen scientists, the forty thousand volunteers who collected data on a staggering 19 million birds - 502 different species - and meets their record breaking volunteer, Chris Reynolds. A 73 year old retired maths teacher, Chris took part in the previous three atlases and walked thousands of miles in all seasons across his patch in the Outer Hebrides. Dawn describes the avifaunal picture revealed in this latest Atlas.In 2009, Williams developed a flywheel - which temporarily stores energy - for their formula 1 car. After the Research and Development was done, the F1 governing body changed the rules, and there was no longer space for a flywheel on their car. No matter, these things have other uses. Mark Smout from Smout Allen has proposed a design for the Isle of Sheppey in Kent, which uses banks of these flywheels to regulate the energy from the nearby wind farm. It also uses spare electricity to grow a sea defence for the island. Marnie Chesterton reports on this flywheel technology and Tim Fox, energy expert at the Institution of Mechanical Engineers describes to Adam other potential solutions for storing energy on the National Grid.Professor Bill Sutherland from the University of Cambridge is a co-author on a new "cheat sheet", published in this week's Nature, to help politicians and policy makers sort the good scientific research from the bad. He talks to Adam about why it's more important and faster, to teach a scientific approach than simply to teach facts.Producer: Fiona Hill.

Global experts in DNA identification are flying to the Philippines to assess whether they can help families to determine, beyond doubt, which of the hundreds of victims of Typhoon Haiyan are their relatives. The International Commission on Missing Persons in Sarajevo used DNA matching to identify the thousands killed in the former Yugoslavia and has since helped in conflict zones around the world. Now, working with Interpol, scientists from the ICMP are called on to assist in victim identification after natural disasters as well, and head of forensic services, Dr Thomas Parsons, tells Adam Rutherford that a team will be sent to the Philippines on Monday.The enormous ash cloud following the 2010 eruption of the Icelandic volcano, Eyjafjallajokell, grounded aircraft across Europe for more than a week and caused unprecedented disruption. Dr Fred Prata has invented a weather radar for ash, and off the Bay of Biscay, his AVOID infra red camera system, the Airborne Volcanic Object Imaging Detector, has just been tested after a ton of Icelandic volcanic ash was dropped by aeroplane into the sky. From France, Dr Prata describes the experiment and Dr Sue Loughlin, Head of Volcanology at the British Geological Survey in Edinburgh, tells Adam how Iceland has become the scientific "supersite" for seismic research.Show Us Your Instrument: Dr Glenn Gibson at the University of Reading with his Robo gut, a full-working model of the human large intestine.Liverpool University's Dr Julian Chantrey, and his PhD student have spent the past 4 years monitoring red squirrels in the Sefton area. Out of the 93 they trapped and blood tested, 5 had antibodies for the normally-deadly squirrel pox, suggesting they had contracted the pox and survived. It's early days but this could mean that reds are developing a level of resistance to the squirrel pox, like rabbits have to myxomatosis. We could be seeing evolution by natural selection in action.Producer: Fiona Hill.

A hundred thousand Britons are being asked to donate their sequenced DNA, their personal genome, to a vast database on the internet, so scientists can use the information for medical and genetic research. The Personal Genome Project-UK was launched today and participants are being warned, as part of the screening process, that their anonymity won't be guaranteed. Stephan Beck, Professor of Medical Genomics at University College London's Cancer Institute and the Director of PGP-UK, tells Dr Lucie Green that anonymised genetic databases aren't impregnable, and that it is already possible for an individual's identity to be established using jigsaw identification. This new "open access" approach, he says, will rely on altruistic early-adopters who are comfortable with having their genetic data, their medical history and their personal details freely available as a tool for research. Jane Kaye, Director of the Centre for Law, Health and Emerging Technologies at the University of Oxford, describes the rigorous selection procedure for would-be volunteers.Scientists at Queen Mary University London and Imperial have created Good Vibrations by playing pop songs to solar panels. Exposing zinc oxide PV cells to noise alongside light generated up to 50% more current than just light alone. Pop and rock music had the most effect, while classical was the least effective genre.Thanks to the Russians' enthusiasm for dash-cams in their cars, the twenty metre asteroid that came crashing into the atmosphere above the town of Chelyabinsk, East of the Urals in February this year, was the most filmed and photographed event of its kind. Mobile phones and cameras captured the meteor, moving at 19 kilometres a second (that's 60 times the speed of sound) and the enormous damage caused by the airblast. The plethora of footage allowed researchers to shed light on our understanding of asteroid impacts and in a new study, published in Nature, Professor Peter Brown from the University of Western Ontario in Canada questions whether using nuclear explosions is an appropriate way to model these airbursts and whether telescopes could underestimate the frequency of these events.Seventh November this year is the hundredth anniversary of the death of Alfred Russel Wallace. As the Natural History Museum in London unveils the first statue of him, we ask why, as co-discoverer of the theory of evolution by natural selection, Wallace doesn't share Charles Darwin's spotlight. Dr George Beccaloni, from the NHM, explains to Lucie why Wallace deserves both glory and commemoration.Producer: Fiona Hill.

A NASA spacecraft the size of a sofa is currently orbiting the Moon, gathering information about the toxic perils of moon dust. Dirt from the moon is sharp, spiky and sticky and it caused enormous problems for early astronauts as Professor Sara Russell from the Natural History Museum tells Dr Lucie Green. Joining Lucie from NASA HQ in Washington DC, Sarah Noble, programme scientist on the LADEE Mission, tells her that understanding the make-up and movement of lunar dust is vital to ensure humans can work on the Moon in the future.Electroceuticals is the new research area for medicine, tapping into the electricity transmitted through the vast network of nerves that run throughout our bodies. Kerri Smith reports on how the body's natural wiring could become a valuable tool for treating organs affected by disease. Glaxo Smith Kline has just invested £30 million into electroceuticals and researchers in labs around the world are working on devices that could "plug" into troubled organs and correct the electrical signals that have gone awry.The impact of man-made climate change tends to focus on the things we can see, like shrinking glaciers or the weather. But a study published in Nature this week by a team in Spain, focuses on the impact underground, on the make up of the soil in a sizeable part of the earth's land, the drylands. The impact of increasing aridity is dramatic, affecting the delicate balance between nitrogen, carbon and phosphorus, with serious implications for soil fertility. David Wardle, Professor of Soil and Plant Ecology at the Swedish Institute of Agriculture, tells Lucie Green that this important new study spells out the risks when delicate chemical balances are upset.Oceanographer, Helen Czerski, revealed her instrument, a giant buoy, on Inside Science's Show Us Your Instrument slot in the summer. This week, Helen is launching the buoy into the stormy seas South of Greenland, and Inside Science listeners are being called on to come up with a name ! Bob anyone ? Or Lucie's suggestion, Buoyonce ?Dogs wag their tails more to the right when they're happy and relaxed; more to the left when they're anxious. Georgio Vallortigara, Professor of Neuroscience at the University of Trento in Italy has now shown that asymmetrical tail wagging actually means something to other dogs.Producer: Fiona Hill.

Britain's legacy of nuclear waste dates back 60 plus years and a long term solution to deal with it hasn't yet been found. After this week's announcement that the UK will have a new nuclear power station, Hinkley C in Somerset, Dr Adam Rutherford asks Professor Sue Ion, former Director of Technology at British Nuclear Fuels and Chair of the European Commission's Science and Technology Committee, Euratom, how much extra waste this new plant will add to the radioactive stockpile.Eighteen years ago the first planet outside of our solar system was discovered, "51 Pegasi b". This week the tally of exoplanets passed one thousand, and as astronomer Dr Stuart Clark tells Adam, an earth twin isn't part of the planetary list.....yet.Show Us Your Instrument: Public Astronomer Dr Marek Kukula introduces the original Six Pip Masterclock at the Greenwich Observatory. This clock was used in the 1920s to send the time signals down a telephone line to the BBC, for transmission to the whole country over the radio. That's not the case now, and Adam goes down into the basement of Broadcasting House in London in search of the atomic clock that's now used to generate the Greenwich Time Signal and the famous BBC pips.iGEM is a global biology competition that allows students to build their own organisms. The UK has two teams going to the grand final next week. Adam goes to meet the team from Imperial College London, who have made a bacterium which produces plastic.Producer: Fiona Hill.

The link between genetics and a child's academic performance hit the headlines this week when Education Secretary, Michael Gove's outgoing special advisor, Dominic Cummings, called for education policy to incorporate the science behind genes and cognitive development. Mr Cummings cited the Professor of Behavioural Genetics, Robert Plomin, as a major source, and Professor Plomin tells Dr Adam Rutherford what he thinks about the way his research has been interpreted. Steve Jones, Emeritus Professor of Genetics from University College London says why he believes genetics and education is such a controversial subject.Fifty years ago, researchers tried, and failed, to teach chimpanzees English. They concluded that chimp noises were merely basic expressions of fear or pleasure. Dr Katie Slocombe from York University has shown that chimp language is far more tactical, machiavellian even, than that.The inventor of Golden Rice, the genetically modified crop, tells Adam Rutherford that he agrees with Environment Secretary, Owen Paterson, that those who attack GM crops are "wicked". Professor Ingo Potrykus from the Swiss Federal Institute of Technology in Zurich developed Golden Rice enriched with Vitamin A in 1999 and believes that opposition to GM foods has prevented the crop being grown and widely planted. But, nearly 80 years old, Professor Potrykus tells Inside Science that he still believes Golden Rice will be grown and eaten throughout the world during his lifetime. Rhys Phillips makes lightning at a Cardiff laboratory for this week's Show Us Your Instrument. It's used to test aeroplane parts. Less metal in an aircraft makes it lighter but too little and the lightning may damage the plane. The safest way to test is to make your own lightning, at ground level.Producer: Fiona Hill.

The US has shut down government science with potentially devastating results for American and international science projects. Many individual scientists are banned from talking but Matt Hourihan from the American Association for the Advancement of Science tells Dr Adam Rutherford about the serious consequences of the political squabble.Roland Pease gives the low down on this week's Nobel Prizes including the much anticipated Physics gong for Peter Higgs' for his eponymous boson.Marnie Chesterton reports on the new iCollections at the Natural History Museum where butterflies collected 150 years ago are shedding new light on the changing British climate. And after studies this week linked cardiovascular disease to aircraft noise, Kevin McConway, Professor of Applied Statistics at the Open University quantifies the risks of complex science being distorted by simple headlines.Producer: Fiona Hill.

Dr Adam Rutherford and guests explore the scientific mysteries of the menopause after scientists in the US and Japan successfully induced pregnancy in post-menopausal women.Also in the programme, we hear from decision scientist Baruch Fischhoff on the difficulties of trying to communicate uncertainty in science in the wake of the latest report from the Intergovernmental Panel on Climate Change. Following on from last week's Fracking report, one listener, Professor Kevin Anderson of the University of Manchester, raises his concerns about the consequences of exploiting shale gas for UK carbon emissions.This week's show us your instrument comes from the Rutherford Appleton Laboratory in Oxfordshire, where Dan Faircloth tends to the ISIS particle accelerator.

Fracking is touted as a technology that will lower UK energy bills. It's a controversial technique which unlocks natural gas from shale rock. But it raises many environmental concerns. So what does the science say? Adam Rutherford sorts science fact from science fiction, putting your frack FAQs to four experts. Reporter Gaia Vince travels to a gas well site in Warrington to discover the various techniques used to extract gas onshore in the UK.Also on the programme, your feedback to last week's story on new fingerprint technology.Lipstick forensics: Professor Michael Went at the University of Kent has developed a new method for unpicking the make-up of make up left at crime scenes.And this week's Show Us Your Instrument comes from Cardiff University, as we showcase herpetologist Dr Rhys Jones's snake hook. It's a low-tech but vital piece of kit for handling snakes. It's also useful for scrumping.

As Syria agrees to destroying its chemical weapon stocks, Adam Rutherford looks at how you solve a problem like Sarin. Dr Joanna Kidd from King's College London gives us a potted history of chemical weaponry. Environmental toxicologist, Prof Alastair Hay, from Leeds University has worked on chemical warfare issues for four decades. In the 1990s, he identified mustard gas and sarin residues from soil samples in Iraq, confirming their use by Saddam Hussein. He talks to Adam about the challenges of destroying chemical weapons in Syria. Reporter Roland Pease looks at a new phone app, OpenSignal, which uses your smartphone's sensors to help improve weather models. Today, London Underground workers are starting to boycott a new clock-in system, which uses their fingerprint for identification. Meanwhile, Apple fans are camping outside stores waiting to buy the new iPhone, which features a fingerprint scanner. Adam talks to Dr Farzin Deravi from the University of Kent about how fingerprint identification works and whether it can be fooled with a gummy bear. Plus he asks technology journalist Kate Bevan if we should worry about the security issues surrounding biometric passwords. Finally this week, Dr Pedro Viegas shows us his instrument - a dino drill. It's being used to uncover the Bristol dinosaur, a 210 million year old Thecodontosaurus.

As Spanish researchers unveil new stem cell research, Dr Adam Rutherford talks to Professor of Regenerative Medicine Fiona Watt. They look back at the history of stem cell research and what the future holds for regenerative medicine. Last week's discussion on science practicals generated huge amounts of feedback. Some listeners consider school practicals the secret to their success, others remember nothing more than breaking test tubes and blowing things up. Professor Robin Millar researches the best ways to teach science practicals; we ask him to respond to some of the points you raised. We unveil the mystery of the phantom head. Not an 18-rated horror film, but a dentists' training tool. This week's Show Us Your Instrument comes from Newcastle University's School of Dental Sciences. And, where there's muck, there's brass. In Newcastle, they're looking to sewage as a renewable alternative energy supply. It's flushed down the drains, but Northumbrian Water have taken a 'waste not want not' approach to our biological effluent. They are going to great efforts to recover energy from sewage and pump it back into the National Grid.

Dr Adam Rutherford asks whether the proposed ice wall around the Fukushima nuclear plant will finally halt the radioactive leaks they've suffered since the tsunami in 2011.BBC Tokyo correspondent Rupert Wingfield-Hayes gives an insider's view on the current crisis and public reaction to the £300m rescue plan announced this week. Plus, Prof Neil Hyatt from Sheffield University describes the challenges ahead in building the ice wall, and decontaminating the water used to cool the crippled nuclear reactors.Amongst the many challenges of sending a manned mission to Mars is the problem of 'menu fatigue'. Eating the same ready meals for several years could send anyone over the edge. NASA recently completed a four month Mars simulation on a barren volcano in Hawaii, their mission was to invent dishes to recreate on the Red Planet. Cooking doesn't get tougher than this.School practicals may be popular with students and teachers but recent research suggests that they might not be a useful way to teach science. Is the aim to train up the technicians of the future, or teach children how to think scientifically? Science teacher and writer Alom Shaha and Prof Jim Iley, from the Royal Society of Chemistry, discuss how to make science demo more effective. And the best way to make cheese on toast.Finally, Dr Pete Etchells from the University of Bath shows us his instrument - an eye-tracker used in psychology experiments. Recent applications include discovering why professional cricketers are better than amateurs, and whether horses are conscious.

Science is supposed to be objective. Research by Professor John Ioannidis suggests the reality is falling short of the ideal. He talks to Alice Roberts about bias in softer science disciplines, and how having an American on the team leads to more exaggerated claims for the results. Is this due to the extra pressures they face to come up with new and exciting findings? Bomb-detection dogs are currently taught each new explosive, one at a time. It's time consuming, A team at Lincoln University are investigating a new approach, categorisation. It's known that dogs can visually recognise groups of items, but can they do this with a different sense, smell? Reporter Marnie Chesterton went to Lincoln to see the team at work. This week's Show Us Your Instrument comes from The Rutherford Appleton Lab. Dr Ceri Brenner shows us the high energy Gemini laser. It can be used to research the conditions inside stars. A team at Cardiff University are harnessing the power of social media to measure, for the first time, the kinds of wildlife being killed on Britain's roads. Gruesome, yes, but assessing the problem is the first step towards conservation solutions. Seen a roadkill blackspot near you? Become a splatter spotter and do your bit for science.

Prof Alice Roberts goes Inside Science this week to discuss the science behind artificial reefs. The 70 concrete blocks around Gibraltar are currently causing a diplomatic controversy as the Spanish government claim they restrict commercial fishing. We look at how artificial reefs are made and what effect they have on the marine environment.Bees have faced multiple dangers in recent years, from pesticides to parasites. Reporter Roland Pease visits a team at the University of Bath who are putting beehives into a CAT scanner to discover whether they can help breed bees that are more resistant to disease.Humans are special; our uniquely evolved feet testify to that, allowing us to walk upright. At least, that's what anatomy students have been taught for the past 70 years. Research published his week by a team at the University of Liverpool shows that our feet are much more ape-like than we thought. And some of us may have more 'apey' feet than others.Finally, this week Prof Andrea Sella from University College London shows us his instrument - an NMR spectrometer. This magnetic beast determines not only the chemical composition of molecules, but also their 3D structure.

Influenza causes up to five million cases of severe illness and half a million deaths globally every year. Yet, as Adam Rutherford finds out, our current vaccination strategy is a seasonal game of chance, based on guessing the strain that will appear next. Research published this week in Science Translational Medicine, by a team from Mount Sinai Hospital in New York, offers hope for a universal flu vaccine, based on newly discovered antibodies.Earlier this week, a game to help combat ash dieback was launched on Facebook, called Fraxinus. Reporter Gaia Vince looks at the growing trend for using games to solve scientific problems. Is this new way of gathering and analysing data changing the way science is done?Currently half of all clinical trials are not published worldwide. Adam talks to Ben Goldacre, author of Bad Pharma, about his new campaign 'AllTrials', which aims to change that.Finally this week, physicist Peter Barham shows us his instrument - a spy camera system that he's designed to recognise penguins.
