Speak, Memory: Research Challenges Theory Of Memory Storage
During sleep, freshly minted memories move from the hippocampus, part of the "old"brain, to the neocortex, or "new"brain, for long-term storage. This has been the reigning theory for decades. Brown University research provides the strongest proof yet of this interaction between the old and new brains -- and offers surprising evidence that challenges critical details of this theory of learning and memory. Results appear in Nature Neuroscience. Ethical And Scientific Guidelines For Study Of Captive Great Apes
With genome maps adding new appreciation of the very close relationship between humans and the great apes, scientists at the University of California, San Diego have proposed a series of ethical and scientific guidelines for the expected increase in research on these, our closest evolutionary cousins. Practice Of Farming Reaches Back Farther Than Thought
Microscopic residues of plants recovered from stone tools that people were using in Panama 3,000 to 7,800 years ago show that people were engaged in the practice of agriculture much earlier than previously thought. Las Vegas: An Unconventional History
This Public Broadcasting Service (PBS) American Experience program "steps into the world of bright lights and back-room deals to illuminate what makes Las Vegas perhaps the most American city in the country."The website companion to the show includes features on the city's economy, casino architecture, atomic tourism, entertainers and other people involved in the city's history, a gallery of Las Vegas weddings, a timeline, teacher's guide, and more. University Of Chicago Researchers Find Human Brain Still Evolving
Human evolution, Chicago researchers report, is still under way, in what has become our most important organ: the brain. In two related papers published in Science, they show that two genes linked to brain size are rapidly evolving in humans. The researchers looked at variations of microcephalin and ASPM within modern humans, and found for each gene one class of variants has arisen recently and has been spreading rapidly because it is favored by selection. Cryoablation Is Effective In Treating Cancer Patients' Pain
Freezing tumors is an effective way to treat a cancer patient's pain, preliminary results of a new study show. [Ironic] An Italian pensioner committed suicide after his wife fell in
Recalling the end of Romeo and Juliet, the 70-year-old man, Ettore, who had sat by his wife's bedside for four months after she slipped into a coma following a heart attack, finally gave up hope and gassed himself in the garage of his family home.Less than a day later, his wife, Rossana, woke up in her hospital bed in Padua and immediately asked for him. Duke 'All-optical' Switch Could Advance Light-based Telecommunications
Duke University physicists have developed a switching technique that uses a very weak beam of light to control a much stronger beam. The achievement could make optical telecommunications devices perform far more efficiently, and perhaps also aid in the development of futuristic quantum communications devices, the scientists said. Bones Don't Pay A Price When Fat Is Lost Through Exercise
Debunking the myth that exercising to lose excess body fat, unlike dieting alone, comes at a cost to bone health, researchers at Johns Hopkins have determined that for those age 55 to 75, a moderate program of physical exercise generally maintains bone mass and, in some cases, offers modest improvements. Bacterial 'Switch Gene' Regulates Oceans' Sulfur Emissions Into The Ai
A team of researchers, led by marine microbial ecologist Mary Ann Moran at the University of Georgia, has discovered a bacterial "switch gene"in two groups of plankton. This gene helps determine whether certain marine bacterioplankton convert a sulfur compound to one that rises into the atmosphere and affects the earth's temperature or remains climatically inactive in the seas.
