Media, Web Companies Set Copyright Rules
A bar of chocolate, a long soak in the bath, a snooze in the middle of the afternoon, a leisurely stroll in the park. These are the things that make us the most happy, according to new research from The University of Nottingham.
Moonlight Inspires Corals to Spawn
(AP) -- A coalition of major media and Internet companies Thursday issued a set of guidelines for handling copyright-protected videos on large user-generated sites such as MySpace.
More Research Urged on Stress Disorder
(AP) -- By the light, of the silvery moon, corals get in tune, and soon, it's a spawning delight. While their silvery moon was written about people, songwriters Ray Noble and Snookie Lanson understood the motivation. Now, scientists think they may have found out how reef-building corals manage to coordinate their sex lives in moonlight bay.
Research Leads to Self-Improving Chips with Speed 'Warping'
(AP) -- There isn't enough evidence to tell if most treatments for post-traumatic stress disorder work, says a scientific review that highlights the urgency of finding answers as thousands of suffering veterans return from Iraq.
Researchers underscore limitations of genetic ancestry tests
Imagine owning an automobile that can change its engine to suit your driving needs - when you`re tooling about town, it works like a super-fast sports car; when you`re hauling a heavy load, it operates like a strong, durable truck engine. While this turn-on-a-dime flexibility is impossible for cars to achieve, it is now possible for today`s computer chips.
Sticky mussels inspire biomedical engineer yet again
Although many people rely on commercially available genetic tests for insights into their ancestry, the tests have significant limitations according to Deborah Bolnick, assistant professor of anthropology at The University of Texas at Austin.
Ability to handle stress, depression linked to variations in brain structure and function
Mussels are delicious when cooked in a white wine broth, but they also have two other well-known qualities before they`re put in a pot: they stick to virtually all inorganic and organic surfaces, and they stick with amazing tenacity.
Cross-species transplant in rhesus macaques is step toward diabetes cure for humans
Researchers at UT Southwestern Medical Center have found in mice that the ability or inability to cope with stress is linked to specific differences in the way brain cells communicate with each other.
Elephants tell human friends from foes by scent and clothing color
With an eye on curing diabetes, scientists at Washington University School of Medicine in St. Louis have successfully transplanted embryonic pig pancreatic cells destined to produce insulin into diabetic macaque monkeys - all without the need for risky immune suppression drugs that prevent rejection.
Immune cells fighting chronic infections become progressively 'exhausted,' ineffective
Elephants are remarkably perceptive when it comes to recognizing specific ethnic groups of people that vary in the degree of danger they are likely to pose, reveals a new study published online on October 18th by Current Biology, a Cell Press publication.
Mice offer clues to the roots of human resilience
A new study of immune cells battling a chronic viral infection shows that the cells, called T cells, become exhausted by the fight in specific ways, undergoing profound changes that make them progressively less effective over time.
Neandertals, humans share key changes to 'language gene'
When faced with adversity, some people succumb to debilitating psychological diseases including posttraumatic stress disorder and depression, while others are able to remain remarkably optimistic.
SAP 3Q Rises on License Sales
A new study published online on October 18th in Current Biology reveals that adaptive changes in a human gene involved in speech and language were shared by our closest extinct relatives, the Neandertals. The finding reveals that the human form of the gene arose much earlier than scientists had estimated previously. It also raises the possibility that Neandertals possessed some of the...
Scientists find how amber becomes death trap for watery creatures
(AP) -- SAP AG, the world's largest maker of business-software applications, said Thursday its third-quarter profit rose 10 percent thanks to increased license sales.
Sidestepping cancer's chaperone
Shiny amber jewelry and a mucky Florida swamp have given scientists a window into an ancient ecosystem that could be anywhere from 15 million to 130 million years old.
St. Jude identifies the specific cell that causes eye cancer, disproving long-held theory
Cancerous tumors are wildly unfavorable environments. Struggling for oxygen and nutrients while being bombarded by the body`s defense systems, tumor cells in fact require sophisticated adaptations to survive and grow. For decades, scientists have sought ways to circumvent these adaptations to destroy cancer. Now, researchers at the University of Massachusetts Medical School (UMMS), have defined a...
Stress: Brain yields clues about why some succumb while others prevail
Investigators at St. Jude Children's Research Hospital have identified the cell that gives rise to the eye cancer retinoblastoma, disproving a long-standing principle of nerve growth and development. The finding suggests for the first time that it may one day be possible for scientists to induce fully developed neurons to multiply and coax the injured brain to repair itself.
UK Spy Agency Puts Out Call to Gamers
Results of a new study may one day help scientists learn how to enhance a naturally occurring mechanism in the brain that promotes resilience to psychological stress. Researchers funded by the National Institutes of Health`s National Institute of Mental Health (NIMH) found that, in a mouse model, the ability to adapt to stress is driven by a distinctly different molecular mechanism than is the...
UTMB researchers to be honored at 'Oscars of invention'
(AP) -- A British intelligence agency is seeking spies in cyberspace. GCHQ, the surveillance arm of British intelligence, said Thursday it hopes to attract computer-savvy young recruits by embedding job ads within video games such as "Tom Clancy's Splinter Cell: Double Agent."
West Nile virus' spread through nerve cells linked to serious complication
Two University of Texas Medical Branch at Galveston (UTMB) researchers who pioneered the development of an artificial immune system that mimics that of the human body and will allow researchers to speed the development of vaccines are being honored tonight at a showcase known as the Oscars of invention held at Chicago`s Navy Pier.
Brain measurements could lead to better devices to move injured or artificial limbs
Scientists believe they have found an explanation for a puzzling and serious complication of West Nile virus infection.
Computer solution to delivery problem
Neuroscientists at the Hebrew University of Jerusalem have developed a novel approach for measuring and deciphering brain activity that holds out promise of providing improved movements of natural or artificial limbs by those who have been injured or paralyzed.
First Analysis of the Water Requirements of a Hydrogen Economy
With the gift-giving season almost upon us and increasing concerns about the environmental effects of all those deliveries and pickups, it is timely that researchers should turn their attention to the so-called Traveling Salesman Problem. Writing in a forthcoming issue of the Inderscience publication the International Journal of Logistics Systems and Management, researchers suggest a new approach...
Hungry microbes share out the carbon in the roots of plants
One of the touted benefits of the futuristic US hydrogen economy is that the hydrogen supplyin the form of wateris virtually limitless. This assumption is taken for granted so much that no major study has fully considered just how much water a sustainable hydrogen economy would need.
Sugars made by plants are rapidly used by microbes living in their roots, according to new research at the University of York, creating a short cut in the carbon cycle that is vital to life on earth.
