About 3 million people in the US are diagnosed every year with bipolar disorder, a psychiatric condition characterized by dramatic shifts in mood from depression to mania. Currently, the standard treatment includes a combination of psychotherapy and prescription medications such as mood stabilizers and antipsychotics.

Scientists have identified 66 alien plant and animal species, not yet established in the European Union, that pose the greatest potential threat to biodiversity and ecosystems in the region.

From an initial working list of 329 alien species considered to pose threats to biodiversity recently published by the EU, scientists have derived and agreed a list of eight species considered to be very high risk, 40 considered to be high risk, and 18 considered to be medium risk.

With fierce winds and flooding rains, hurricanes can be disasters for people -- and for ecosystems. These devastating storms have major effects on tropical forests, demolishing tree canopies and leaving behind debris that piles up in watershed streams and on forest floors.

Argonne researchers have demonstrated a new technique's viability for membranes.

Whether it's tap water or a cup of coffee, almost everything we drink passes through some kind of filter. The ability to transform liquids this way is essential to daily life, yet it often rests on relatively delicate membranes that can quickly clog or degrade.

When households in sub-Saharan Africa don't have an adequate number of insecticide-treated bed nets, pregnant women and children under five are the most likely family members to sleep under the ones they have, leaving men and school-aged children more exposed to malaria, new Johns Hopkins Center for Communication Programs (CCP) research suggests. CCP is based at the Johns Hopkins Bloomberg School of Public Health.

Black adolescents living in the United States tend to receive the influenza vaccine at significantly lower rates than their white and Hispanic counterparts, according to Florida State University researchers.

A new study, led by former FSU graduate student Noah Webb, along with current graduate student Benjamin Dowd-Arrow and Associate Professors of Sociology Miles Taylor and Amy Burdette, was recently published in Public Health Reports.

Fire and water. Timeless, opposing forces, they are actually linked in powerful ways that can have major impacts on communities and ecosystems.

The 2011 Las Conchas mega-fire in New Mexico burned more than 150,000 acres and threatened the Los Alamos National Laboratory. Now, using data from the fire, researchers at Los Alamos have created an experimental model that will help us better understand the interactions of fire and water in the soil.

DURHAM, N.C. -- Hypoxic dead zones, which occur when dissolved oxygen levels in water drop so low that fish and other aquatic animals living there suffocate, are well-documented problems in many coastal waters.

Now, a new Duke University-led study reveals they also occur in freshwater urban streams.

WOODS HOLE, Mass. -- Why do we age? Despite more than a century of research (and a vast industry of youth-promising products), what causes our cells and organs to deteriorate with age is still unknown.

Small, local patches of habitat could be playing a much bigger role in conserving biodiversity than you think, according to new research.

The global study just published in the Proceedings of the National Academy of Sciences (see article here) looked at the conservation values of vegetation patches in 27 countries on four continents, and considered their size and distance to other habitat.

The results were surprising according to lead researcher Professor Brendan Wintle from Melbourne University.
