College women exceed NIAAA drinking guidelines more frequently than college men
In 1990, the National Institute on Alcohol Abuse and Alcoholism issued guidelines that define low-risk drinking, which differ for men and women. New research shows that female college student drinkers exceed NIAAA guidelines for weekly drinking more frequently than their male counterparts.

Youth who have their first drink during puberty have higher levels of later d...
The earlier the age at which youth take their first alcoholic drink, the greater the risk of later alcohol problems.

Now we know why old scizophrenia medicine works on antibiotics-resistant bact...
An old medicine for schizophrenia is effective at treating something completely different than it was designed for: antibiotic-resistant bacteria. So far it has been a mystery how this old schizophrenia medicine works, but now researchers have figured it out. This can lead to a new medicine against ...

Attacking MRSA with metals from antibacterial clays
Medical researchers have come up with a new approach for developing effective, topical antibacterial agents -- one that draws on a naturally occurring substance recognized since antiquity for its medicinal properties: clay.

Frogs, salamanders and climate change
Increasingly erratic rainfall patterns can lead to declines in southeastern frog and salamander populations, but protecting ponds can improve their plight.

Individuals who drink heavily and smoke may show 'early aging' of the brain
Alcohol treatment interventions work best when patients understand and are actively involved in the process. A first-of-its-kind study looks at the interactive effects of smoking status and age on neurocognition in one-month-abstinent alcohol dependent (AD) individuals in treatment. Results show tha...

Ketamine shows significant therapeutic benefit in people with treatment-resis...
Drug associated with rapid antidepressant effect in largest clinical trial to-date.

Consuming coffee linked to lower risk of an autoimmune liver disease
Regular consumption of coffee is associated with a reduced risk of primary sclerosing cholangitis (PSC), an autoimmune liver disease.

For combat veterans suffering from post-traumatic stress disorder, 'fear circ...
Chronic trauma can inflict lasting damage to brain regions associated with fear and anxiety. Previous imaging studies of people with post-traumatic stress disorder, or PTSD, have shown that these brain regions can over-or under-react in response to stressful tasks.

Reading rock to understand how climate change unfolds
Geologists reads rock, looking for the natural rules that govern the Earth?s climate in the absence of human activity. New work is challenging many assumptions about the ways drastic climate change unfolds ? and what to expect next.

Mars rover Opportunity examines clay clues in rock
NASA's senior Mars rover, Opportunity, is driving to a new study area after a dramatic finish to 20 months on "Cape York" with examination of a rock intensely altered by water.

Women's reproductive ability may be related to immune system status
Anthropologists have showed that a woman's reproductive function may be tied to her immune system's status.

New approach to improving treatment for MS and other conditions
Working with lab mice models of multiple sclerosis (MS), scientists have detected a novel molecular target for the design of drugs that could be safer and more effective than current FDA-approved medications against MS.

Invasive species: 'away-field advantage' weaker than ecologists thought
For decades, ecologists have assumed the worst invasive species?such as brown tree snakes and kudzu?have an ?away-field advantage.? They succeed because they do better in their new territories than they do at home. A new study reveals that this fundamental assumption is not nearly as common as peopl...

Nine-year-old Mars rover passes 40-year-old record
While Apollo 17 astronauts Eugene Cernan and Harrison Schmitt visited Earth's moon for three days in December 1972, they drove their mission's Lunar Roving Vehicle 19.3 nautical miles (22.210 statute miles or 35.744 kilometers). That was the farthest total distance for any NASA vehicle driving on a ...

New malaria test kit gives a boost to elimination efforts worldwide
A new, highly sensitive blood test that quickly detects even the lowest levels of malaria parasites in the body could make a dramatic difference in efforts to tackle the disease.

Genome sequence of Tibetan antelope sheds new light on high-altitude adaptation
How can the Tibetan antelope live at elevations of 4,000-5,000m on the Qinghai-Tibetan Plateau? Investigators now provide evidence of genetic factors that may be associated with the species' adaption to harsh highland environments.

New era of fisheries policy needed to secure nutrition for millions
A new study argues that for fisheries policies to be effective they must take in to account not just fish stock conservation and environmental issues, but also research data on the patterns and dynamics of fish trade, markets and user consumption.

Electric and magnetic characteristics of a material which could be used in sp...
Materials belonging to the family of dilute magnetic oxides (DMOs) - an oxide-based variant of the dilute magnetic semiconductors - are good candidates for spintronics applications.

Climate change may have little impact on tropical lizards: Study contradicts ...
Climate change may have little impact on many species of tropical lizards, contradicting a host of recent studies that predict their widespread extinction in a rapidly warming planet.
