With only a few walls between an astronaut and a rapid death, what do we know about the various dangers to the human body during space travel? Chris Smith spoke with Mark Shelhamer, a professor of Otolaryngology - Head and Neck Surgery at John Hopkins Medical School - about which space hazards are deemed most pressing for our up-and-coming astronauts...

This month, as the eLife Podcast hits its century, we hear how getting frog dads to cross-foster tadpoles has revealed the way in which some frogs come by their microbiomes, the ants that do gene therapy, signs that disease causes a breakdown in nutrient exchange between the elements of the microbiome, how fungi reprogram immune cells to cause over-reactions in sepsis, and new insights into how tapeworm larvae in the brain cause seizures...

As the global population heads toward 10 billion, the pressure on agriculture is mounting. With that in mind, the UK's Advanced Research and Invention Agency (ARIA) has announced millions of pounds worth of funding for crops enhanced through synthetic biology by designing entirely new chromosomes and chloroplasts, starting with the potato, as Angie Burnett, the ARIA Programme Director and plant biologist leading this initiative explains to Marushka Soobben...

"Warp speed, Mr Sulu." It's the kind of command we've only heard in science fiction - until now. Did a team of scientists just bend spacetime using nothing but sparks in a lab? That's right - not black holes, not neutron stars - electrical sparks. A new experiment claims to have created tiny ripples in the very fabric of space and time, right here on Earth. If it holds up, it could be the first step toward technologies once thought possible only in science fiction: warp drives, fusion reactors, even medical time control. But is it the real deal - or just a very flashy illusion? I sat down with... Like this podcast? Please help us by supporting the Naked Scientists

In the eLife podcast, a university compost heap has turned up Finland's first documented "giant virus". Also, why monkeys de-sand their supper, and how learning more languages actually makes brain tissue thinner. Then, the link between sugar and neonatal sepsis, and how a cancer controls its hydra host by bestowing it with extra tentacles... Like this podcast?

Cambridge University have informed us that, for cost cutting reasons, they intend to make Dr Chris Smith redundant. Naturally, this jeopardises the Naked Scientists programme, which is produced under his role. He will also lose his medical job. We regard this as a terrible decision and we intend to protest. Please listen to this short podcast to hear how you can help. Together we hope we can turn around this terrible decision... Like this podcast? Please help us by supporting the Naked Scientists

In episode 10 of the Cambridge Prisms Podcast, the shocking finding that as many as 2 invertebrate species are going extinct each week in Australia: what can be done? Also, the shot in the arm that AI is administering to the drug discovery industry, how do you measure the microplastic problem, and why climate tipping points are a serious problem for the drinking water industry.

Your personal data could soon be stored not on a phone or server but locked inside a molecule so tiny it's invisible to the naked eye. Researchers have cracked the code on storing digital information in synthetic molecules called polymers - long chains of anything from plastic to protein made from building blocks known as monomers. Each monomer sends out a unique electrical signal that a special electrochemical technique can decode, turning these tiny sequences into passwords or secret messages. This game-changing technology could redefine data security without relying on traditional storage... Like this podcast? Please help us by supporting the Naked Scientists

What if a parasite could rewire your brain - not to harm you, but to make you... more romantic? This week on The Naked Scientists, we're exploring the bizarre world of Wolbachia - a bacterium that turns female fruit flies into mating machines. Marushka Soobben with the story...
