Naked Science Question and Answer show
|
|
Footballs in space, mind-controlled machines and long-lasting bubbles join your questions on this week's Naked Scientists Question and Answer show. We discover the feminine side of prostate cancer and the robot that can walk up walls, and also hear how a computer has designed the next generation of mosquito repellents. Plus, we revisit the Phoenix mission on Mars, and also find out how surfing the internet can contribute more carbon to climate change than surfing the skies in an aeroplane! Plus, in Kitchen Science, Dave demonstrates a psychedelic effect with some milk.

Robots are becoming more and more important in war zones, disaster areas, and in every day life, in order to view places people cant access easily or safely. At the moment flying robots can't last for very long because they use so much power, and ground based robots are constrained to fairly flat su...
Scientists have found convincing evidence for the basis of "good bacteria" and how they contribute to health. Caltech researcher Sarkis Masmanian and his colleagues, writing in this week's Nature, have shown that a common friendly gut inhabitant, an anaerobic bacterium called Bactero...
Prostate cancer affects more than 670,000 men worldwide, and researchers have known for a long time that the disease is fuelled by the male sex hormone testosterone. Men with prostate cancer are often given drugs that block the production or actions for testosterone in the body, and these trea...
Orbiters around planets such as Mars have given us an unprecedented view of the whole surface, but sometimes you actually have to go down and have a look. Last week the Mars Polar Lander touched down and will be digging holes and studying the chemistry, but only in one place. Rovers like Spirit and ...
US researchers have developed a system which translates brain activity into movements of a prosthetic arm, a discovery which could help patients paralysed by strokes, injuries and other diseases to regain their independence.

Ever since Prince Charles’ infamous “grey goo” speech, there have been concerns about the safety of nanoparticles in the environment. Adding fuel to the fire, last week researchers in Edinburgh published results in the journal Nature Nanotechnology showing that carbon nanotubes of a certain le...

Interviews
Last week's show was all about Mars, just hours before the Phoenix mission was due to land. So did it touch down safely?
Airlines often get a lot of criticism from the green movement for the amount of greenhouse gases they emit. But could the internet be overtaking them?
Mark Peplow joins us once again from the Royal Society of Chemistry's magazine, Chemistry World...
Questions

Do Bees have knees?
We’ve all heard the expression “the bee’s knees.” What I’d really like to know is, do bees really have knees?

How do hairs go grey?
Do hairs lose their pigment and then go grey or do the coloured ones fall out and they get replaced by the grey ones?

Burp-related Optical Illusions?
If you’re driving up a motorway and get a lorry next to you on the front wheel of the lorry the nuts are sticking out. As it’s driving it looks like a ring because it’s going so fast. If you really burp the nuts then stop whilst you’re burping. Once you stop they start revolving again.

Vampires and Soylent Green
If vampires were real, could a person live on blood alone? Also, in the film Soylent Green they dried people out to make tablets for other people to eat. Is that feasible?

Impact craters on the Moon
With regards impact craters on the Earth - how much would they differ on the Moon because of the lack of atmosphere, reduced gravity. Would a small meteor make a bigger crater?
A fellow on the show asked about living off blood or soylent green. He might be interested in the information on this I'm not sure I...
