Antimicrobial soap; GAIA; Stone-age jellybones; Antarctica

Antibacterial soaps and body washes make up an industry worth millions of pounds, but in the USA, producers have been told that they have just over a year to prove their products are safe, or, re-label or reformulate them. Many believe that using antimicrobial soaps, which often include the chemicals triclosan or triclocarban, keeps you clean and reduces the chance of getting ill or passing on germs to others. But the Food and Drug Administration in the USA says it's the job of manufacturers to demonstrate the benefits, to balance any potential risks. Professor Jodi Lindsay, expert in microbial pathogenesis from St Georges, University of London, tells Dr Adam Rutherford where this leaves British and European consumers.The world's most powerful satellite camera was launched today into space. Its mission, to map the billion stars in our galaxy. Professor Gerry Gilmore, Principal Investigator for GAIA, tells Inside Science about the planned "walk through the Milky Way" and BBC Science Correspondent, Jonathan Amos, spells out how GAIA could help detect future asteroids, like the one that wiped out the dinosaurs on earth.Just after the Second World War in a site in North Yorkshire, the discovery of a flint blade triggered the discovery of one of the world's most important Mesolithic or Stone Age sites. What makes Star Carr so special is that organic artefacts, bone harpoons, deer headdresses and even homesteads, were preserved in the peat 11000 years ago. But these precious artefacts are in trouble. Changing acidic conditions are turning the Mesolithic remains to jelly. Sue Nelson reports from the Vale of Pickering on how archaeologists are working with chemists to try to pinpoint exactly why the Stone Age remains are deteriorating so quickly.And Professor Chris Turney talks to Adam from his research ship in Commonwealth Bay in the Antarctic, where he is leading a team of scientists to recreate the journey made by Douglas Mawson, 100 years ago, on the Australasian Antarctic Expedition.Producer: Fiona Hill.

Bird Atlas; Flywheels; Energy capture; Science lessons for MPs

Dawn Balmer shares insights from the Bird Atlas project, with 40,000 volunteers documenting 502 bird species in the UK and Ireland. Flywheels designed for F1 cars now store wind farm energy in Kent. Science literacy for MPs is crucial, citing Fred Sanger's contributions to DNA sequencing.

DNA to ID typhoon victims; Volcanic ash; Hope for red squirrels; Robogut

Global experts in DNA identification assist in identifying victims of Typhoon Haiyan in the Philippines. A new weather radar for volcanic ash is tested off the Bay of Biscay. Dr. Glenn Gibson showcases his Robo gut, a model of the human large intestine. Research on red squirrel populations and disease impact shows potential for immunity to squirrel pox virus.

Personal genome; Solar cells and music; Asteroids; Alfred Russel Wallace

A hundred thousand Britons are being asked to donate their sequenced DNA, their personal genome, to a vast database on the internet, so scientists can use the information for medical and genetic research. The Personal Genome Project-UK was launched today and participants are being warned, as part of the screening process, that their anonymity won't be guaranteed. Stephan Beck, Professor of Medical Genomics at University College London's Cancer Institute and the Director of PGP-UK, tells Dr Lucie Green that anonymised genetic databases aren't impregnable, and that it is already possible for an individual's identity to be established using jigsaw identification. This new "open access" approach, he says, will rely on altruistic early-adopters who are comfortable with having their genetic data, their medical history and their personal details freely available as a tool for research. Jane Kaye, Director of the Centre for Law, Health and Emerging Technologies at the University of Oxford, describes the rigorous selection procedure for would-be volunteers.Scientists at Queen Mary University London and Imperial have created Good Vibrations by playing pop songs to solar panels. Exposing zinc oxide PV cells to noise alongside light generated up to 50% more current than just light alone. Pop and rock music had the most effect, while classical was the least effective genre.Thanks to the Russians' enthusiasm for dash-cams in their cars, the twenty metre asteroid that came crashing into the atmosphere above the town of Chelyabinsk, East of the Urals in February this year, was the most filmed and photographed event of its kind. Mobile phones and cameras captured the meteor, moving at 19 kilometres a second (that's 60 times the speed of sound) and the enormous damage caused by the airblast. The plethora of footage allowed researchers to shed light on our understanding of asteroid impacts and in a new study, published in Nature, Professor Peter Brown from the University of Western Ontario in Canada questions whether using nuclear explosions is an appropriate way to model these airbursts and whether telescopes could underestimate the frequency of these events.Seventh November this year is the hundredth anniversary of the death of Alfred Russel Wallace. As the Natural History Museum in London unveils the first statue of him, we ask why, as co-discoverer of the theory of evolution by natural selection, Wallace doesn't share Charles Darwin's spotlight. Dr George Beccaloni, from the NHM, explains to Lucie why Wallace deserves both glory and commemoration.Producer: Fiona Hill.

Genetics and education; Golden Rice inventor; Chimp Chatter and Lightning Lab

The link between genetics and a child's academic performance hit the headlines this week when Education Secretary, Michael Gove's outgoing special advisor, Dominic Cummings, called for education policy to incorporate the science behind genes and cognitive development. Mr Cummings cited the Professor of Behavioural Genetics, Robert Plomin, as a major source, and Professor Plomin tells Dr Adam Rutherford what he thinks about the way his research has been interpreted. Steve Jones, Emeritus Professor of Genetics from University College London says why he believes genetics and education is such a controversial subject.Fifty years ago, researchers tried, and failed, to teach chimpanzees English. They concluded that chimp noises were merely basic expressions of fear or pleasure. Dr Katie Slocombe from York University has shown that chimp language is far more tactical, machiavellian even, than that.The inventor of Golden Rice, the genetically modified crop, tells Adam Rutherford that he agrees with Environment Secretary, Owen Paterson, that those who attack GM crops are "wicked". Professor Ingo Potrykus from the Swiss Federal Institute of Technology in Zurich developed Golden Rice enriched with Vitamin A in 1999 and believes that opposition to GM foods has prevented the crop being grown and widely planted. But, nearly 80 years old, Professor Potrykus tells Inside Science that he still believes Golden Rice will be grown and eaten throughout the world during his lifetime. Rhys Phillips makes lightning at a Cardiff laboratory for this week's Show Us Your Instrument. It's used to test aeroplane parts. Less metal in an aircraft makes it lighter but too little and the lightning may damage the plane. The safest way to test is to make your own lightning, at ground level.Producer: Fiona Hill.
