Mars volcanic deposit tells of warm and wet environment
A team led by planetary geologists at Brown University has discovered mounds of a mineral deposited on a volcanic cone less than 3.5 billion years ago that speak of a warm and wet past and may preserve evidence of one of the most recent habitable microenvironments on Mars.

Anti-inflammatory drugs currently used to treat diseases such as rheumatoid arthritis may also help prevent cognitive decline after surgery, according to a new study led by researchers at UCSF and colleagues at Imperial College, London.
Earth's first great predator wasn't
The meters-long, carnivorous "shrimp" from hell that once ruled the seas of Earth a half billion years ago may have been a real softy, it turns out. A new 3-D modeling of the mouth parts of the Anomalocaris, along with evidence that these parts were not hard like teeth, but flexible, shows that the famed predator could not have been munching on the hard shells of trilobites and other such creatures of the early seas.

New drug may provide more cost-effective stroke prevention than warfarin, Stanford/VA study shows
A newly approved drug may be a cost-effective way to prevent stroke in patients with an irregular heart rhythm ― and may also offer patients better health outcomes than the commonly prescribed, but potentially risky, blood thinner warfarin.
Fox Chase researchers identify risk factors for the spread of breast cancer to lymph nodes
Some scientists argue that evidence of LVI does not necessarily mean that the disease will recur in the lymph nodes after radiation to the breast alone, but research from Fox Chase Cancer Center now shows that the appearance of LVI in the breast tissue does in fact predict recurrence of breast in the regional lymph nodes
Fish show unique parenting skills
Discus fish are surprisingly attentive parents, scientists have found.

Europe’s Plagues Came From China, Study Finds
In the issue of Nature Genetics published online Sunday, they conclude that all three of the great waves of plague originated from China, where the root of their tree is situated. Plague would have reached Europe across the Silk Road, they say.
Kuiper Belt Objects Don Coats of Many Colors
Kuiper Belt objects are far from being charred, barren mini-worlds. Their complex internal dynamics create a colorful array of rocky bodies -- color-coded depending on their orbits.
Black raspberries may prevent colon cancer, study finds
Black raspberries are highly effective in preventing colorectal tumors in two mouse models of the disease, according to a University of Illinois at Chicago study.
DHA 'fish oil' supplements do not seem to slow cognitive, functional decline in Alzheimer's disease
Patients with mild to moderate Alzheimer's disease (AD) who received supplementation with the omega-3 fatty acid docosahexaenoic acid (DHA), believed to possibly reduce the risk of AD, did not experience a reduction in the rate of cognitive and functional decline, compared to patients who received placebo, according to a study in the November 3 issue of JAMA, a theme issue on aging.

Study shows how ancient plants and soil fungi turned the Earth green
A new breakthrough by scientists at the University of Sheffield has shed light on how the Earth's first plants began to colonise the land over 470 million years ago by forming a partnership with soil fungi.
Nostrums: Caution Urged on Cholesterol-Lowering Supplement
Americans trying to avoid cholesterol-lowering drugs spend tens of millions of dollars each year on Chinese red yeast rice, a supplement found to lower LDL, or “bad,” cholesterol. But the amount of the active ingredient in the supplement varies widely, and one in three tested products contained a substance that may be toxic to the kidneys.
Virus breakthrough raises hope over ending common cold
Scientists say they have made a landmark discovery which could pave the way for new drugs to beat illnesses like the common cold.
Vampire Moth Discovered -- Evolution at Work
A previously unknown population of vampire moths has been found in Siberia. And in a twist worthy of a Halloween horror movie, entomologists say the bloodsuckers may have evolved from a purely fruit-eating species.
A sweet discovery raises hope for treating Ebola, Lassa, Marburg and other fast-acting viruses
New research published in the Journal of Leukocyte Biology suggests that a purified form of a product modified from simple sugar molecules can eradicate killer viruses by mobilizing white blood cells
Asthma drug prevents spread of breast cancer: study
A drug commonly used in Japan and Korea to treat asthma has been found to stop the spread of breast cancer cells traditionally resistant to chemotherapy, according to a new study led by St. Michael's pathologist Dr. Gerald Prud'homme.

Study: Brain 'energy crisis' may spark Parkinson's
Parkinson's disease may stem from an energy crisis in the brain, years before symptoms appear. If the research pans out, it points to a possible new approach for Parkinson's: Giving a boost to a key power switch inside brain cells in hopes of slowing the disease's inevitable march instead of just treating symptoms...
