Warming waters could render larger parts of Antarctica's continental shelf habitable for crustaceans

Supercomputers might soon predict political events such as the fall of Mubarak.

Apple's OS X Lion update may look great in a demo and at first, but three things need fixing.

LiveScience.com - The aisles of a pharmacy are full of supplements and herbs claiming to lower blood pressure, but which ones really work? A pair of cardiologists combed the scientific literature for studies on effective ways to treat blood pressure and concluded, in a new paper, that there are good data that some of the nondrug remedies work, but there is scant evidence for others.

Based on an extensive survey of the literature pertaining to the Chinese caterpillar fungus, a fungus with high medicinal and economic values, researchers investigated a total of 91 insect species and found 57 of these to be potential hosts to the fungus.

A new study concludes that genetic research drawing correlations between specific genes, environmental variables and the combined impact they have on the development of some psychiatric illnesses needs additional scrutiny and replication before being accepted as true.

Researchers in Israel have found that HFI, a hormonal condition that leads to the growth of bone masses in the inner skull, is far more likely to be found in young women today than in the past, when it was typically found in post-menopausal women. HFI, which does not have a cure, can lead to symptoms such as chronic headaches, weight gain, and thyroid...

A new article describes the background, usage, and value of the Legume Integrated Pest Management Pest Information Platform for Extension and Education (ipmPIPE). The goal of the Legume ipmPIPE is to identify causes of losses (yield, quality, economic) in legumes and assist producers in minimizing those losses by implementing integrated pest management of pathogens and insect...

Mantis shrimp make noise with each individual seeming to have its own "voice" with which to communicate. The research team noted the "rumbles" were synchronized.

In a significant advance for cosmetic and reconstructive medicine, scientists have unveiled a new method for making synthetic collagen. The new material, which forms from a liquid in as little as an hour, has many of the properties of natural collagen and may prove useful as a scaffold for regenerating new tissues and organs from stem...

An analysis of a skull from the most complete early hominid fossils ever found suggests the large, complex human brain may have evolved more rapidly and at a later time than some other human characteristics. If Australopithecus sediba is a human ancestor, as some suggest, then its fossils could help resolve long-standing debates about human brain evolution, say...

Although the burning of natural gas emits far less carbon dioxide than coal, a new study concludes that a greater reliance on natural gas would fail to significantly slow down climate change. Coal releases more carbon dioxide, but it also releases particles that cool the...

To achieve the goals laid out by the White House's Childhood Obesity Task Force, researchers concluded that a shared emphasis on both obesity prevention and treatment strategies is required. Prevention programs alone cannot appropriately tackle the epidemic affecting children who are already obese, particularly minorities. Obesity treatment strategies need to be a key part of the...

Calisolar is the fifth green technology company in the last 18 months to announce plans to build manufacturing facilities in Mississippi, which is actively pursuing environmentally-friendly jobs.

An analysis of the genome of a superbug has yielded crucial, novel information that could aid efforts to counteract the bacterium's resistance to an antibiotic of last resort.

A new article describes the origin, function, successes, limitations, and future of the Soybean Rust Pest Information Platform for Extension and Education (PIPE).

Reuters - When a Russian rocket failed on its way to orbit last month, it exposed a vulnerability in the International Space Station program that a former NASA astronaut thinks China could help address.

Texas Governor Rick Perry doubles down on his disbelief in climate change science.

Babies can distinguish painful stimuli as different from general touch from around 35-37 weeks gestation -- just before an infant would normally be born -- according to new research.

Researchers have obtained the first high-resolution, three-dimensional images of a cell with a nucleus undergoing cell division. The observations, made using a powerful imaging technique in combination with a new method for slicing cell samples, indicate that one of the characteristic steps of mitosis is significantly different in some...

Narcolepsy is a rare disorder characterized by an excessive urge to sleep at inappropriate times and places. Narcoleptics are also often subject to "cataplexy," a sudden muscle weakness that is triggered by strong emotions. Although most cases of narcolepsy are thought to be caused by complex mechanisms, a small percentage of cases are associated with unidentified inherited mutations. Now, a new...

Scientists have discovered a new gene responsible for Parkinson's disease. The mutation, a single "spelling mistake" among three billion nucleotides in DNA, regulates the mechanism for converting a cell's genetic code into proteins.

Researchers have discovered that an ancient pathway called autophagy also mobilizes and exports cholesterol from cells.
