Rocking the thermometer at 4 trillion degrees Celsius, a subatomic soup that might reflect the state of matter shortly after the Big Bang has set a new world record: It's the hottest substance ever created in a lab. The previous record, recorded at Sandia National Lab in 2006, was a balmy 2 billion degrees Celsius. The core of the sun burns at a chill 15 million degrees. Links to the associated sessions at the American Physical Society Annual Meeting in Washington DC are here and here. More

Laser labels for fruits and veggies Ivanhoe Share
From spinach to tomatoes, contaminated produce has made headlines … and a lot of people sick. When this kind of problem is discovered, one of the challenges is finding the source of the contamination. Now the Food and Drug Administration is looking at new technology to help the produce industry track and trace the fruits and vegetables we eat, from the field to the produce aisle. More U.S. Olympic skeleton team studies sled forces in high-tech simulator Scientific American Share
In the sport of skeleton, where athletes hurtle face first atop a sled the size of a seat cushion down an iced-over concrete track at speeds upwards of 110 kilometers per hour, the smallest details separate success and failure. Researchers at Rensselaer Polytechnic Institute have developed a new simulator to determine the best way to beat wind resistance. More |
