A system for growing heart cells on a microscopic silicon grid that can eavesdrop on their electrical behaviour is giving scientists a much clearer picture of how the heart works and providing a way to test new drugs much more safely. Long term it could lead to the creation of a cardiac repair patch that could be "pasted in" to replace or control damaged heart tissue. The work's taking place in the lab of Harvard's Charles Lieber and he told Chris Smith about what they've been up to... Like this podcast? Please help us by supporting the Naked Scientists

Cells collected from the intestines of patients with the disease cystic fibrosis can be grown in the laboratory dish to produce balls of cells that scientists are calling mini guts. These can be used to test a series of new cystic fibrosis drugs that are now entering the clinic. But because these agents don't work on everyone, finding out who will benefit can mean a laborious trial for the patient. Mini guts on the other hand take just a few weeks to grow and give results in just days or hours. Jeffrey Beekman, from the Wilhelmina Children's Hospital, Utrecht, invented the technique...

Sudden cardiac death in the young, that's an apparently healthy person dying unexpectedly from heart-related issues under the age of 35, is rare but devastating. It is also something of a mystery to many scientists. So how can we try to prevent young people from dying unexpectedly like this? Could genetic screening be the answer? Georgia Mills caught up with Michael Ackerman, from the Mayo Clinic in Minnesota, at the British Cardiovascular Society Conference 2016. Like this podcast?

Carbon dioxide is a problematic greenhouse gas contributing to global warming. Power plants are major emitters of carbon dioxide, but unfortunately, current methods of capturing and storing excess carbon dioxide have not been very effective. Only a small amount of carbon dioxide actually gets stored permanently. But researchers at Columbia University have demonstrated that their unique carbon capture and storage process can actually convert carbon dioxide into environmentally friendly limestone in less than two years.

On June the 1st, Switzerland announced the opening of the world's longest tunnel. Called the Gotthard tunnel, it runs under the Alps to link Northern and Southern Europe; and at 57.5 km, it's fair to say, you certainly wouldn't be able to see the light at the end of it!

Immune cells are essential to the maintenance and repair in our bodies. However, an over-active immune system can lead to diseases such as arthritis, chronically inflamed wounds and atherosclerosis. Therefore, it is imperative to understand and carefully control our immune system activity. Our innate or non-specific immune system, acts as our body's first line of defence, these cells quickly reach the site, form a barrier, remove foreign material, and activate our more sophisticated adaptive immune system. Until now these non-specific immune cells were believed to have no memory and act in a... Like this podcast? Please help us by supporting the Naked Scientists

Earlier this year, the US banned microparticle beads from personal care products, but Europe has yet to follow suit. Now, researchers from Uppsala University are increasing the urgency as for the first time, they have been able to show that fish actually prefer to eat microplastic particles rather than their own food of zooplankton, causing disastrous effects to their survival.

A vaccine that can teach the immune system to attack any type of cancer is being developed and tested by scientists in Germany. Cancer affects one person in every three. It's caused by genetic damage to our cells, which leads them to grow in an uncontrolled and invasive way. But because the cancer cells are part of our own body, the immune system normally ignores them because they're regarded as non-hostile. What Ugur Sahin and his colleagues are doing is to identify a series of chemical markers that are unique to a patient's cancer cells and then turn these into a genetic message that is...

As a nation, the UK are above the intake guidelines for salt, which, for an adult, is 6g per day. To put that into perspective, there's about half a gram in a small packet of crisps, or one ham and cheese sandwich. But what does salt do to our insides? Viknesh Selvarajah from Addenbrooke's Hospital, in Cambridge, researches the impacts of salt and has a very unique perspective on the effects of high blood pressure, as he explained to Chris Smith.

Botox is a popular cosmetic treatment where Botulin toxin-A injections paralyse your facial muscles, which relaxes smile lines and makes your skin appear younger. In comedies, it is often joked about for giving patients frozen expressions. But now, researchers say that having Botox not only makes your face difficult to read, but also impairs your ability to read the emotion of others. This stems from the theory of embodiment. For a person to process an emotion that they see, they are required to mimicking that emotion. When we see our friend smile, our face automatically smiles a little as... Like this podcast?

On February 1, 2016, the World Health Organization declared Zika virus a Public Health Emergency of International Concern with the virus' continued spread through the Americas. Zika, which was previously considered to be fairly harmless, has been linked to birth defects and miscarriages in a dramatic shift that scientists are unable to explain. However, we are now one step closer to understanding this virus as the development of a new mouse model may have solved one piece of the puzzle.

Could limbs have evolved from fish gills? While it might sound fishy, scientists from the University of Cambridge have discovered that the same genetic programme, triggered by a gene called Sonic Hedgehog, is involved in the development of limbs, fins and gills. The idea that the formation of gills and legs might be linked is actually not a new one and was first proposed more than a century ago based on the similarities in appearances of the two structures, but scientists abandoned the notion as fanciful thinking.

We might have sexually transmitted infections to thank for our modern-day monogamous society, according to a new study from Canada this week. Between ten and fifteen thousand years ago, as agriculture was established and humans swapped a hunter gatherer lifestyle for life in larger group settlements, our ancestors also appear to have embraced monogamy - having a single partner, rather than multiple wives. Mathematician Chris Bauch has designed a computer simulation that suggests that, as populations increase in size, the threat of sexual disease drives the switch to monogamy, and the desire to...

The drug LSD, or lysergic acid diethylamide, was first made in the 1930s in Switzerland by chemist Albert Hoffman, who also tried the agent on himself and described his psychedelic experience. LSD was widely used until the 1960s when it was made illegal, so very little research has actually been done using modern neuroscience techniques to look at how LSD affects the brain and how it might be useful therapeutically. Until now, that is. Imperial College's Robin Carhart-Harris has been administering the drug to volunteers, as he explained to Chris Smith... Like this podcast?

Strokes are a major cause of permanent disability and they affect millions of people every year. The cause is usually a lack of blood flow to one part of the brain, which destroys the affected brain area and robs the victim of the ability to perform whatever tasks that brain area used to process. But an electrical current applied to the head for a short time, even years after a stroke, appears to open up new circuits in the brain, restoring some of the lost abilities, as Oxford University's Heidi Johansen-Berg explained to Chris Smith...

Back in the 1960s, US researcher Stanley Milgram stunned the world with a study showing that members of the public were prepared to inflict potentially lethal electric shocks on supposedly innocent volunteers, if a lab-coated scientist ordered them to do so. In fact the recipients of the shocks were actually actors, who escaped unharmed. Milgram's experiments raised many ethical questions - not least about whether it was right to do them at all - and Patrick Haggard from UCL is now trying to find out to what extent people feel a sense of responsibility or control when they're ordered to do...

Results that scientists are describing as "unprecedented" in the treatment of cancer have been announced at a conference this week. A team led by Stanley Riddell, a researcher at the Fred Hutchinson Cancer Research Center in the US, have developed a method to reprogramme the immune system to selectively target cancer cells. This means that, unlike traditional chemotherapy, which can't tell healthy and tumour tissue apart - and this is what causes unpleasant side effects - the immune system acts with surgical precision, selectively weeding out rogue cancer cells while leaving healthy tissue...

Many people make the assumption that climate change means that places will become warmer; and indeed some will. But more important in some ways is how the climate in a particular geography might become more variable. Because, if the temperatures, cloud cover and rainfall become less predictable and operate over a greater range than they have historically, this could affect how the ecosystems - the web of plant and animal life - in those areas can operate. And this week scientists took the first steps towards studying whether this is a real risk and highlighting those areas we need to worry... Like this podcast?
