| NASA's Swift satellite discovers a new black hole in Milky Way galaxy Posted: 05 Oct 2012 01:28 PM PDT NASA's Swift satellite recently detected a rising tide of high-energy X-rays from a source toward the center of our Milky Way galaxy. The outburst, produced by a rare X-ray nova, announced the presence of a previously unknown stellar-mass black hole. |
| 'Disgusted' rats teaching scientists about nausea, work may lead to new cancer treatments Posted: 05 Oct 2012 09:38 AM PDT Nausea is a common and distressing side effect of many drugs and treatments. Unlike vomiting, nausea is not well understood, but new research may soon change that. Researchers believe they've found the mechanism in the brain that is responsible for the sensation of nausea -- with the help of some "disgusted" rats. |
| Posted: 05 Oct 2012 07:09 AM PDT Coyotes are the largest of the mammalian carnivores to have made their way to, and thrived in, urban settings. A researcher estimates that about 2,000 coyotes live in the Chicago metro area. The coyote is "the test case for other animals," he says, such as wolves, bears and mountain lions. |
| How order arises from the random motion of particles in the cosmos Posted: 05 Oct 2012 06:29 AM PDT One of the unsolved mysteries of contemporary science is how highly organized structures can emerge from the random motion of particles. This applies to many situations ranging from astrophysical objects that extend over millions of light years to the birth of life on Earth. |
