Orfield Laboratories' 'anechoic chamber' in the U.S is 99.99% sound absorbent Volunteers see hallucinations after a short while By Ted Thornhill PUBLISHED: 16:35 GMT, 3 April 2012 | UPDATED: 15:39 GMT, 5 April 2012 They say silence is golden – but there’s a room in the U.S that’s so quiet it becomes unbearable after a short time. The longest that anyone has survived in the ‘anechoic chamber’ at Orfield Laboratories in South Minneapolis is just 45 minutes. It’s 99.99 per cent sound absorbent and holds the Guinness World Record for the world’s quietest place, but stay there too long and you may start hallucinating.
55 Cancri A is a Sun-like star some 40 light years away. It has an apparent magnitude of about 6 and so is visible to the naked eye in the constellation of Cancer. This star is unusual in that it is just one of a handful that are known to have at least 5 planets. The innermost of these planets–55 Cancri e–was discovered in 2004 and has since had plenty of attention from astronomers. Various groups have observed the the changes in radial velocity that it causes its parent star. This tells them about that it orbits its star every 18 hours and that its mass is about 8 times Earth’s or about half Neptune’s.

(PhysOrg.com) -- The flickering flame of a candle has generated comparisons with the twinkling sparkle of diamonds for centuries, but new research has discovered the likeness owes more to science than the dreams of poets. Professor Wuzong Zhou, Professor of Chemistry at the University of St Andrews has discovered tiny diamond particles exist in candle flames. His research has made a scientific leap towards solving a mystery which has befuddled people for thousands of years. Since the first candle was invented in ancient China more than 2,000 years ago, many have longed to know what hidden secrets its flames contained. Dr Zhou’s investigation revealed around 1.5 million diamond nanoparticles are created every second in a candle flame as it burns. The leading academic revealed he uncovered the secret ingredient after a challenge from a fellow scientist in combustion.

"If we picture these jets as giant hoses and the water droplets as bullets, the amount shooting out equals a hundred million times the water flowing through the Amazon River every second," said Lars Kristensen , a postdoctoral astronomer at Leiden University in the Netherlands. "We are talking about velocities reaching 200,000 kilometers [124,000 miles] per hour, which is about 80 times faster than bullets flying out of a machine gun," said Kristensen, lead author of the new study detailing the discovery, which has been accepted for publication in the journal (Related: "Dimmest Stars in Universe Spotted?"

The two lead researchers, Gaetan Borgonie of the University of Ghent in Belgium and Tullis Onstott of Princeton University, said the discovery of creatures so far below ground, with nervous, digestive and reproductive systems, was akin to finding “Moby Dick in Lake Ontario.” “This is telling us something brand new,” said Onstott, whose pioneering work in South Africa over the past decade has revolutionized the understanding of microbial life known generally as extremophiles, which live in places long believed to be uninhabitable. “For a relatively complex creature like a nematode to penetrate that deep is simply remarkable,” he said.
