Low Energy, High-Power Processing
This week we're getting inside the workings of the next generation of chips that are set to pack a bigger computing-punch but at a fraction of the energy-expenditure of todays' models: CTO Mike Muller joins us to explain the revolutionary technology that leading microprocessor-maker ARM is developing. Also, energy-efficient world-wide computing - we find out how distributing data-processing demands around the planet can turn waste energy into useful computations, simultaneously saving CO2 emissions, and in the news this week, a new malarial mosquito threat, rejection-free artificial blood...

Leprosy: The Low Down
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 came from in the first place. Plus, why it's time to rethink the workings of the circadian clock, brain scans for bilingualism, cow-stomach bacterial genes for biofuels, and the engineering that lies... Like this podcast?

Analysing Antimatter
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 light and there's also news of a novel way to neutralise HIV, researchers uncover how brains gauge the passage of time, and agriculture on the microscale: scientists have found the world's smallest...

Do Metal Spinal Implants Lure Lightning?
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, why making new computer chips looks set to become easy PC, how stem cells can get to the heart of Long QT Syndrome, feeding the world in 2050 and a new musical device to keep the drummer in the driving...

Would you donate your body to science?
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 their bodies, and the impact the process had on the student's lives. In Naked Engineering, we find out how a design that copies the body's own structure and movements can make better artificial... Like this podcast? Please help us by supporting the Naked Scientists

Back in the Saddle: Getting Paralysed Patients Riding and Rowing
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... Like this podcast?
