The Naked Scientists Podcast

From anti-ague to anti-Alzheimer's agent: over the 112 years since it was first trademarked, Aspirin has evolved from popular painkiller to powerful preventative against heart attacks, strokes and even cancer. In this week's show we trace its history from the extraction of aspirin-like chemicals from willow bark to the creation of the drug itself. Plus, in the news, how the chemistry of life could...

Leprosy goes under the microscope this week as we uncover the origins of one of the oldest known human diseases, recognised this week on World Leprosy Day. A quarter of a million new cases are diagnosed every year, but how is the illness spreading, what damage does it do to the body and can it be stopped? We also hear what archaeologists are unearthing about the history of leprosy and where it cam...

We're analysing the matter of antimatter this week to find out what is antimatter, how is it made and why's it so rare in the Universe? We talk to researchers at CERN who are capturing anti-hydrogen so scientists can study it properly for the first time, and Dave and Meera call in to the hospital to hear how antimatter holds the key to better body scans. Diana discovers how gravity bends a beam of...

Does a metal implant turn a person into a living lightning-conductor or radio receiver, is eye-size important, why is frost bad for freezers, where did the first organic molecules come from, what happens to sparkling drinks in space and why does a bump on the head make you see stars? This week, join Chris, Sarah and Dave as they pit their wits against the latest crop of your top questions. Plus, w...

We're discussing human dissection in this week's Naked Scientists. Chris visits the dissection room to find out how trainee doctors benefit from dissecting real bodies, and why many medical schools are increasingly turning to alternatives. We're joined by physician and film maker Paul Trotman, who followed the lives, and beyond, of three donors to explore the reasons why people choose to donate th...

In this special podcast we focus on the highlights of this year's National Pathology Week. We'll be going behind closed doors for a tour of the pathology labs at Great Ormond Street Hospital, and we'll explore the role of veterinary pathologists in diagnosing and treating animal disease.

In this special episode of the Naked Scientists podcast, we explore the world of Functional Electrical Stimulation (FES), a technology allowing people paralysed from the waist down to row and cycle by using external electrodes to stimulate leg muscles. Michele Vanoncini investigates how it works, what benefits it can bring and talks to some of the people who have used the technique to go for gold....

In this festive episode, can you get drunk through your feet, the chemistry of cocktails, twelve marine critters of Christmas, the best food and drink combos to eschew indigestion, does a carbon fibre bike go faster, why are snowflakes different shapes and a way to impress your peers at the office party by blowing out candles round corners...

Graphene is the focus of this week's Naked Scientists, including how it holds the key to the super-flexible touch screen displays of tomorrow, super-light composites and the next generation of computer chips. In the news, a breakthrough in understanding Alzheimer's Disease, why glider pilots should be paying more attention to how falcons fly and why a new exoplanet has led astronomers to question...

Current breakthroughs in electricity generation and distribution go under the spotlight in this week's sizzling edition of the Naked Scientists. We talk to the team with the electrical equivalent of cold-storage that can put power "on ice" until it's needed, and we hear how bright sparks in the UK are leading the charge to roll out "energy kiosks" to empower rural communities in Africa. We also ch...

How heavy is the Earth? How do snakes digest huge meals? Should I fear falling bullets? We take on these questions and more in this Naked Scientists Question and Answer show! We'll discuss the ideal hair for head lice, the mechanics of using a straw and why men's bits shrink in the cold! In the news we explore the link between jetlag and forgetfulness, discover a moon with an oxygen atmosphere, an...

IQ-elevating agents that can boost brain power are being used by over 10% of university students. But how do these cognitive-equivalents of anabolic steroids for the brain actually work, what are their effects and are they safe? Moreover, is the advantage they confer an ethical one? And if not, should universities be screening students ahead of exams to deter their use? Meanwhile, in the news this...

We set sail to discover the science of sustainable shipping in this week's Naked Scientists. We visit an enormous wave tank to find out how the sea swell can impact on damaged ships, and look at the problems caused by sulphur-rich shipping fuel. Plus, we hoist the SkySail, an enormous parafoil kite that can be deployed from the deck of a ship to cut fuel consumption by up to 60%. In the news we he...

We catch up with cancer research this week including evidence that cancers subvert stem cells to suppress the immune system and how covert "hit and run" viral infections may be triggering a lot more tumours than we first thought. Also, joining us from the National Cancer Research Institute conference in Liverpool, cancer biologist Bob Weinberg explains how he sees cancer becoming a controllable ch...
