Ue bêtise de Cambrai. La soixantaine de très sérieux participants (chercheurs, philosophes, juristes, artistes) au colloque sur la sérendipité organisé du 20 au 30 juillet à Cerisy (Manche) par le CNRS, a reçu, comme mise en bouche, cette friandise. La petite histoire raconte que le berlingot naquit, dans les années 1830, d'une bourde d'un apprenti confiseur. Les clients en raffolèrent tant que la recette fut analysée et conservée.

Héberger ses vidéos sur YouTube ou utiliser un compte Hotmail, est-ce encore Internet ?

Or pour Benjamin Bayart, président de FDN (French Data Network), le plus vieux fournisseur d'accès Internet français, cette structure est en danger.

A team led by Dr. Jordan Grafman of the National Institute of Neurological Disorders and Stroke questioned volunteers about their religious beliefs while monitoring the blood flow in their brains with a scanning machine. Extra blood flow is assumed to reflect the activity of neurons in a specific region of the brain.

Different networks of neurons sprang into action when subjects were asked their view of three sets of statements about the religious beliefs, Dr. Grafman and colleagues report in this week's Proceedings of the National Academy of Sciences.

Scientists will warn this week that rising sea levels, triggered by global warming, pose a far greater danger to the planet than previously estimated. There is now a major risk that many coastal areas around the world will be inundated by the end of the century because Antarctic and Greenland ice sheets are melting faster than previously estimated.

Francis Lapique Watchmen, based on the 1980s DC Comics 12-part comic book series (later adapted as a graphic novel), hits theaters tomorrow. Die-hard fans of the original publication may fret over its faithfulness to the series, but studio execs also worried about their movie's faithfulness to science. To set their minds at ease, they placed a call to Jim Kakalios, a physics professor at the University of Minnesota.

Imagine how hard it would be to stick to a budget in a store with no prices. Well, that's pretty much how we buy electricity today. Your utility company sends you a bill at the end of the month with very few details. Most people don't know how much electricity their appliances use, where in the house they are wasting electricity, or how much the bill might go up during different seasons. But in a world where everyone had a detailed understanding of their home energy use, we could find all sorts of ways to save energy and lower electricity bills. In fact, studies show that access to home energy information results in savings between 5-15% on monthly electricity bills. It may not sound like much, but if half of America's households cut their energy demand by 10 percent, it would be the equivalent of taking eight million cars off the road.
