 Do dogs get ticklish? What wakes up mosquitoes at meal times? Do animals use weapons? In this fast-paced Question and Answer show we also focus on the nuclear threat from Fukushima and hear how gut bugs raise the risk of heart disease, why flaps for wind turbines have got engineers in a spin, and why tidiness stops stereotyping. Plus, how to make a balloon fireproof and what causes dark circles under the eyes when we get tired... Listen Now

A new paper from researchers in the US, published in the journal Nature this week, provides an interesting angle – they think that it might be the bacteria in your gut that turn fat in your diet into the gloop that clogs your arteries.
Flaps on wind turbines may make wind power more economic
In a landmark breakthrough this week, Japanese scientists have used stem cells to grow a new retina in a dish, which could hold the key to one day producing a replacement retina for patients blinded by diseases or eye injuries...
Manners maketh man, and a tidy street stops stereotyping - In a surprise finding from the Netherlands, researchers have discovered that choas and clutter cause people to be far more prejudiced than when things are kept tidy.

Is there a difference in the amount of radiation that is absorbed in the ground and the amount that rises into the atmosphere?
How can water become radioactive? Or is the water just carrying radioactive particles which could technically be filtered out?
How does food become radioactive? I saw on the news that the Japanese government is setting regulations for acceptable amounts of radiation. how can I protect my son?
When atoms become radioactive, what kind of radiation comes out? gamma rays? x-rays? light?
Everyone talks about the spent fuel needing to be constantly cooled. Has anyone investigated a way to use the heat to make electricity? Perhaps to charge a back up battery, to run a pump in an emergency.
To investigate the impact of geology on the spread of pollution, scientists in Oxford are studying how water travels underground across a flood plain. But at this time of year, the research involves getting wet, cold and muddy, as Richard Hollingham discovered….
Chris,
There has been much made recently about animals making and using tools, from primates to birds. Has anyone ever observed nonhuman animals using found objects as weapons?
Thanks,
