A revolution in energy-efficient, environmentally-sound, and powerfully-flexible lighting is coming to businesses and homes, according to a new article.
A new study supports earlier findings by stating that changes in cosmic rays most likely do not contribute to climate change.
Marine scientists have developed the world’s first portable system for measuring cetacean hearing sensitivity.
Researchers have created a catalogue of tissue-specific processes involved in hundreds of inherited diseases. These results could help treat diseases such as breast cancer, Parkinson disease, heart diseases and autism.
In everyday social exchanges, being mean to people has a lot more impact than being nice, research has shown. Feeling slighted can have a bigger difference on how a person responds than being the recipient of perceived generosity, even if the net value of the social transaction is the same, the research on reciprocity -- giving and taking --...

Airline pilots who have flown for many years may be at risk of DNA damage from prolonged exposure to cosmic ionizing radiation, suggests a study in Occupational and Environmental Medicine.
An enzyme in the hypothalamus appears to regulate feeding behavior. Researchers have found that overactivity of a brain enzyme may play a role in preventing weight gain and obesity.
Polar bears -- especially the marginal individuals like some sub-adult males -- could adapt to changes in ice and the ability to hunt seals by eating snow goose eggs. According to new calculations, bear movement should coordinate more and more with nesting as the Arctic warms, especially near Hudson...
As the cold weather creeps in, so do brown recluse spiders. True to their name, the brown recluse is a shy, reclusive spider looking for a warm home. Drawn to clutter, closets and complex storage environments, the spiders actually want to stay away from humans. But, if care is not taken, people could find themselves sharing their home with one of 'the big three,' according to entomologists. Often,...
In a major cancer prevention study, long-term supplementation with vitamin E or C did not reduce the risk of prostate or other cancers for nearly 15,000 male physicians.
People who use weight training to ease their lower back pain are better off than those who choose other forms of exercise such as jogging.
Stepping onto a scale after a calorie-filled holiday season isn't an activity many 21st-century Americans relish. But in the late 19th century, scales were all the rage at festive gatherings -- the 1800s' answer to Guitar Hero. "A family would think it fun to weigh themselves before and after a big holiday dinner to see how much they had gained," said Deborah I. Levine, Ph.D. "Knowing your weight...
A rat thought extinct for 11 million years and a hot-pink, cyanide-producing dragon millipede are among a thousand new species discovered in the Greater Mekong Region of Southeast Asia in the last decade, according to a new report by World Wildlife Fund. First Contact in the Greater Mekong reports that 1,068 species were discovered or newly identified by science between 1997 and 2007 -- which...
A breakthrough technique that allows scientists to view individually-labeled tumor cells as they move about in real time in a live mouse may enable scientists to develop microenvironment-specific drugs against cancer.
The antidiabetes drug rosiglitazone may have the potential to protect kidney function in patients with a condition called focal segmental glomerulosclerosis, according to a new study. The phase I clinical findings indicate that the drug warrants further study in phase II and phase III...
Scientists have developed a new optical technique that holds promise for minimally invasive screening methods for the early diagnosis of cancer. The researchers have shown for the first time that nanoscale changes are present in cells extremely early on in carcinogenesis. Their simple yet sensitive technique can detect subtle abnormal changes in human colon cancer cells even when those same cells...
Rsearchers have created a microbial ecosystem smaller than a stick of gum that sheds new light on the plankton-eat-plankton world at the bottom of the aquatic food chain. The work may lead to better predictions of marine microbes' global-scale influence on climate.
Why do Gap brand jeans appeal to people who seek intimacy in relationships? It may be a result of their upbringing. According to a new study, people's relationship styles can affect their brand choices.
It's hard to study something with any rigor if the subject can't be produced uniformly and efficiently. Researchers who study double-walled carbon nanotubes find themselves in just this predicament. The problem is that current techniques for synthesizing double-walled carbon nanotubes also produce unwanted single- and multi-walled nanotubes. Researchers now offer a clever solution: They used a...
A group of five endemic Hawaiian songbird species were historically classified as "honeyeaters" due to striking similarities to birds of the same name in Australasia. Scientists at the Smithsonian Institution, however, have discovered that the Hawaiian birds share no close relationship with the other honeyeaters and in fact represent a new family of birds -- unfortunately, all members of the new...
Scientists are expanding the search for extraterrestrial life -- and they've set their sights on some very unearthly planets. Cold 'super-Earths' -- giant, "snowball" planets that astronomers have spied on the outskirts of faraway solar systems -- could potentially support some kind of life, they have found. Such planets are plentiful; experts estimate that one-third of all solar systems contain...
Use of the steroid medication dexamethasone is effective in reducing nausea and vomiting after tonsillectomies for children, but also is associated with an increased risk of postoperative bleeding, according to a new study.
New research could contribute to the development of a vaccine and cure for West Nile virus and Dengue fever.
Now that navigation systems are here to stay, we can hardly imagine life without them. Aside from private use for getting about on roads, they play an essential role in air and ocean traffic, and even in rail transport for guiding and monitoring trains. Now researchers are developing positioning and navigation technologies to be used in the field of traffic logistics and for emergency services....
