Let me ask you this: ‘Are bananas radioactive and is it true that eating too many can kill you?’

Yes, you will certainly die from radiation poisoning if you are able to eat 10,000,000 bananas at once. You may also witness chronic symptoms if you eat 274 bananas a day for seven years. — Yes, you will certainly die from radiation poisoning if you are able to eat 10,000,000 bananas at once.

British researchers devise material so dark it looks like a black hole

British scientists have created a material which absorbs all but 0.035 per cent of light, a new world record, and is so dark the human eye struggles to discern what it is that it is seeing, giving the appearance of a black hole. (Credit: Surrey Nano Systems)

Boron ‘buckyball’ discovered

Researchers have shown that clusters of 40 boron atoms form a molecular cage similar to the carbon buckyball. This is the first experimental evidence that such a boron cage structure exists. (Credit: Wang lab / Brown University)

How To Measure A Sun-Like Star’s Age

Growth of structure tells us how normal and dark matter scatter

The colored curves describe different velocity dependencies of the scattering strength; it is scaling as v to the nth power. The horizontal axis, k, is a measure of how separated two points in space might be; larger k corresponds to smaller physical separation. The vertical axis (technically known as a “power spectrum”) describes how correlated two points separated by a scale 1/k are; higher number mean more correlation. The one point with error bars shows that most of the models the authors consider are not very favored by the data. (Credit: C. Dvorkin, K. Blum, and M. Kamionkowski)

NASA: Sun’s corona much larger than previously thought

Scientists used these observations of the sun's atmosphere (the bright light of the sun itself is blocked by the black circle at the middle) from NASA's Solar Terrestrial Relations Observatory on Aug. 5, 2007, to define the outer limits of the solar atmosphere, the corona.
