BBC Inside Science Folgen

Dr Adam Rutherford asks whether the proposed ice wall around the Fukushima nuclear plant will finally halt the radioactive leaks they've suffered since the tsunami in 2011.BBC Tokyo correspondent Rupert Wingfield-Hayes gives an insider's view on the current crisis and public reaction to the £300m rescue plan announced this week. Plus, Prof Neil Hyatt from Sheffield University describes the challenges ahead in building the ice wall, and decontaminating the water used to cool the crippled nuclear reactors.Amongst the many challenges of sending a manned mission to Mars is the problem of 'menu fatigue'. Eating the same ready meals for several years could send anyone over the edge. NASA recently completed a four month Mars simulation on a barren volcano in Hawaii, their mission was to invent dishes to recreate on the Red Planet. Cooking doesn't get tougher than this.School practicals may be popular with students and teachers but recent research suggests that they might not be a useful way to teach science. Is the aim to train up the technicians of the future, or teach children how to think scientifically? Science teacher and writer Alom Shaha and Prof Jim Iley, from the Royal Society of Chemistry, discuss how to make science demo more effective. And the best way to make cheese on toast.Finally, Dr Pete Etchells from the University of Bath shows us his instrument - an eye-tracker used in psychology experiments. Recent applications include discovering why professional cricketers are better than amateurs, and whether horses are conscious.

Science is supposed to be objective. Research by Professor John Ioannidis suggests the reality is falling short of the ideal. He talks to Alice Roberts about bias in softer science disciplines, and how having an American on the team leads to more exaggerated claims for the results. Is this due to the extra pressures they face to come up with new and exciting findings? Bomb-detection dogs are currently taught each new explosive, one at a time. It's time consuming, A team at Lincoln University are investigating a new approach, categorisation. It's known that dogs can visually recognise groups of items, but can they do this with a different sense, smell? Reporter Marnie Chesterton went to Lincoln to see the team at work. This week's Show Us Your Instrument comes from The Rutherford Appleton Lab. Dr Ceri Brenner shows us the high energy Gemini laser. It can be used to research the conditions inside stars. A team at Cardiff University are harnessing the power of social media to measure, for the first time, the kinds of wildlife being killed on Britain's roads. Gruesome, yes, but assessing the problem is the first step towards conservation solutions. Seen a roadkill blackspot near you? Become a splatter spotter and do your bit for science.

Prof Alice Roberts goes Inside Science this week to discuss the science behind artificial reefs. The 70 concrete blocks around Gibraltar are currently causing a diplomatic controversy as the Spanish government claim they restrict commercial fishing. We look at how artificial reefs are made and what effect they have on the marine environment.Bees have faced multiple dangers in recent years, from pesticides to parasites. Reporter Roland Pease visits a team at the University of Bath who are putting beehives into a CAT scanner to discover whether they can help breed bees that are more resistant to disease.Humans are special; our uniquely evolved feet testify to that, allowing us to walk upright. At least, that's what anatomy students have been taught for the past 70 years. Research published his week by a team at the University of Liverpool shows that our feet are much more ape-like than we thought. And some of us may have more 'apey' feet than others.Finally, this week Prof Andrea Sella from University College London shows us his instrument - an NMR spectrometer. This magnetic beast determines not only the chemical composition of molecules, but also their 3D structure.
