Happiness comes cheap - even for millionaires

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.

Media, Web Companies Set Copyright Rules

(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.

Moonlight Inspires Corals to Spawn

(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.

More Research Urged on Stress Disorder

(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.

Research Leads to Self-Improving Chips with Speed 'Warping'

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

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.

Neandertals, humans share key changes to 'language gene'

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...

SAP 3Q Rises on License Sales

(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

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...

St. Jude identifies the specific cell that causes eye cancer, disproving long-held theory

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.

Stress: Brain yields clues about why some succumb while others prevail

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...

UK Spy Agency Puts Out Call to Gamers

(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."

UTMB researchers to be honored at 'Oscars of invention'

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.

Computer solution to delivery problem

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...

First Analysis of the Water Requirements of a Hydrogen Economy

One of the touted benefits of the futuristic US hydrogen economy is that the hydrogen supply—in the form of water—is 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.
