Childhood pneumonia is the number one killer of children under the age of five worldwide. The disease is a particular challenge for those living in developing countries, where there is a lack of clinical expertise and appropriate equipment to diagnose the disease. Adopting a technique called machine learning, scientists at Oxford University have taken clinical data from children with pneumonia to 'teach' a machine to identify critical symptoms and diagnose future cases. This machine can be something as easily distributed as a mobile phone, giving those who don't have easy access to doctors... Like this podcast? Please help us by supporting the Naked Scientists

One in 20 people develop colorectal cancer in their lifetime, making it the second-most common form cancer in Europe. Surgery is an option for treatment, but this can result in incomplete removal of the tumour. Now, researchers from MIT have developed a hydrogen patch with three types of therapy applied directly to the tumour itself. Their anti-cancer patch was tested on lab mice and caused the cancer to go into complete remission. Lucka Bibic attempted to uncover some of the patch's secrets from researcher Dr Natalie Artzi from MIT... Like this podcast? Please help us by supporting the Naked Scientists

Researchers at the University of Helsinki have developed a chewing robot to study the tie between tooth wear and the dietary patterns of animals. Their shiny stainless-steel chewing machine with 3D printed parts can now show how the paleodiet of the animals and their tooth wear rate affected their lifespan as Aleksis Karme explained to Lucka Bibic.

People who feel well tend to live well. They have a better immunity against infections and lower susceptibility to ill-health. Stress and depression, on the other hand, are linked to poorer functioning of the immune system, weaker responses to vaccination and, overall, higher rates of morbidity. But how a healthy mind makes for a healthy body wasn't known. Now, by artificially stimulating the reward circuitry in the brains of mice, scientists in Israel have shown that one of the nerve pathways in the body - called the sympathetic nervous system - can directly manipulate the immune system....

The most sensitive "electronic nose" ever has been built by scientists in Belgium. The portable "E-nose" uses spongy structures called metal-organic frameworks to pick up minute traces of molecules including harmful nerve gases. Lucka Bibic spoke to inventor Rob Ameloot...

It's summertime again and along with ice cream, sunburn and our other favourite British traditions, it's time for the Royal Society's Summer Science Exhibition, in London. We've been to see what's been going on Like this podcast? Please help us by supporting the Naked Scientists

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

Days of squeezing the last drop from your shampoo bottles are over! Thanks to researchers from the US, we now have a material which allows sticky liquids to flow freely AND this has big implications for recycling, as Philip Brown explained to Lucka Bibic...

Helium is the stuff that goes into party balloons and is also an essential ingredient in hospital MRI scanners. Most people have heard of helium but not many realise that we're in danger of running out of it. Luckily, Jon Gluyas from Durham University, has come up with a new way of finding it. Claire Armstrong spoke to him to hear how... Like this podcast? Please help us by supporting the Naked Scientists

Today, NASA's Juno spacecraft has plunged into uncharted territory, flying closer to Jupiter than we've ever been before.

Back in February the World Health Organisation declared the zika virus epidemic in Brazil to be a public health emergency of international concern. At the top of the list was the link between Zika infection and babies being born with microcephaly or an abnormally small head. Now scientists in the US have taken the first steps towards developing a much-needed vaccine, which they've so far tested successfully on mice. Dan Barouch from Harvard University spoke to Chris Smith... Like this podcast? Please help us by supporting the Naked Scientists

Solar Impulse is a unique plane, powered not by jet fuel, but solar energy and it is currently on a record-breaking tour around the world. But how does that plane work and what is it like to fly? What happens when the sun begins to fade and the nigh falls over the ocean? Can a solar plane keep flying? Lucka Bibic caught up with co-pilot Andre Borschberg to ask about his green aviation mission. 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...

When it comes to making musical instruments, there's as much science in today's violins as there is art. While many manufacturers around the world are still creating wooden violins, others are turning to alternative materials such as carbon fibre. But, as Kat Arney discovered, the natural world may provide even more options for making instruments with exciting new sound properties. Like this podcast?

Chronic Heart Failure is the inability of your heart to effectively pump blood around your body and affects over half a million people in the UK alone. So what causes it and could treatments lie in something as simple as iron? Doctor Paul Kalra is a cardiologist from Portsmouth Hospital and he gave Chris Smith the lowdown. Like this podcast?

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. Fanny Yuen spoke with Dr. Juerg Matter to hear more about his pilot study. Like this podcast? Please help us by supporting the Naked Scientists

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! Our resident technology expert Peter Cowley talked Connie Orbach through the project. Like this podcast? Please help us by supporting the Naked Scientists

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. Fanny Yuen and spoke with Dr. Oona Lnnstedt to better understand the issue. Like this podcast? Please help us by supporting the Naked Scientists
