The world is always on the lookout for new drugs - but they're not easy to make. Synthesising them is often an expensive and prolonged process. But what if we could employ a miniature assistant to do it for us? That's what a team from the MRC Laboratory of Molecular Biology have come up with. They're managed to genetically reprogramme living cells to build complex molecules - molecules that no living thing would ever normally produce. Phil Sansom learned how from researcher Jason Chin...

For thousands of years, humans have used traditional mining techniques involving sinking tunnels or large pits to recover relatively small amounts of useful metals like gold and copper. What remains is usually, at best, a scar on the landscape, large amounts of waste material, and habitat destruction. At worst, the practices have led to environmental catastrophes. Now an international team, including researchers from the University of Western Australia, have found a way to harness the power of electricity to achieve the same mineral recovery but without the environmental costs. By placing... Like this podcast? Please help us by supporting the Naked Scientists

If you live in the UK, you should soon be able to drink vodka... from Chernobyl! Which might sound like a radioactive nightmare, but the stuff is - supposedly - completely safe to drink. Not only do radioactive particles get removed during the distillation process, there were few originally there at all - thanks to how well much of the environment around Chernobyl has recovered since the 1986 disaster. The project is the brainchild of researchers in Ukraine alongside environmental scientist Jim Smith from Portsmouth University. They've just distilled the first batch of their vodka, but...

It's often hardest to think when you've been working all day - especially if your job involves making lots of decisions. Psychologists call this decision fatigue. And evidence has shown that the phenomenon has serious, real-world consequences... beyond making you collapse on the sofa. Now, a study from the University of Cambridge seems to demonstrate that it could make the difference between your bank loan getting approved - or rejected. Lead author Tobias Baer spoke to Eva Higginbotham... Like this podcast? Please help us by supporting the Naked Scientists

The mantis shrimp is a sea creature with a particular party piece. While our eyes are sensitive to three colours, red, green and blue, which our brain uses to make the full rainbow of colours we see, the mantis shrimp is sensitive to 12 to 16 different colours, giving them a much wider spectrum of colours. Scientists in the University of Illinois figured this might be useful, and have created a camera that can see colours we can't. The idea is that if you tag a cancerous tumour with a fluorescent chemical that we can't see, but the camera can, it will give surgeons a quick and easy way to... Like this podcast?

Alexandra Elbakyan is the founder of the website SciHub, and it came out this week that she is being investigated by the FBI. You see, SciHub is an illegal venture: it makes research papers available for free to people who want them, bypassing the fees and subscriptions that journals would normally charge for that access. In this respect they can claim the moral high ground: people who couldn't otherwise afford to access the material can read it. But the way SciHub obtains the journal articles it makes available is not legal; they are said to have obtained access codes from people at... Like this podcast?

Noise pollution can be difficult to live with, and it turns out that plants are also impacted by too much noise, although not in the way you might expect. Jenny Phillips from Texas A&M in San Antonio has been studying the seedlings of native trees around gas wells in New Mexico. She's found that noise pollution can drive away the animals that some plants rely on to spread their seeds, as she explained to Katie Haylor... Like this podcast?

Anorexia nervosa is a cruel, complex and serious mental health condition. It involves deliberately losing weight in order to keep body weight as low as possible. And through investigating brain circuits involved in regulating body weight and which can go awry in obesity, Roger Cone from the University of Michigan and colleagues, along with scientists from Vanderbilt University, have now shown that activating a particular receptor called MC3 in the brains of mice encourages them to eat more, whilst at the same time also suppressing fear and anxiety. And Roger thinks this has interesting... Like this podcast? Please help us by supporting the Naked Scientists

When they're trying to piece together our understanding of ancient Humans and Neanderthals, scientists often have to rely on artifacts found in caves. What scientists wish they had more of was ancient DNA, which would allow them to study how the populations of these groups changed and expanded over time. Now that's about to change thanks to Benjamin Vernot at the Max Planck Institute, as he explained to Eva Higginbotham.... Like this podcast? Please help us by supporting the Naked Scientists
