The greater frequency of droughts, combined with underlying economic, social and environmental risks, means that dry spells have an increasingly destructive impact on vulnerable populations, and particularly on children in the developing world. In a new study by researchers from IIASA and the U.S., the team set out to map at-risk populations at the global scale.
Rainfall variations in the tropics not only potentially influence 40% of the world's population and the stability of the global ecosystem, but also the global hydrologic cycle and energy balance.
Hookah waterpipe use has grown in popularity in recent years -- 1 in 5 college students in the U.S. and Europe have tried it -- but the practice could be more dangerous than other forms of smoking, according to a first-of-its-kind study.
Alzheimer's disease, the most common cause of dementia among the elderly, is characterized by plaques and tangles in the brain, with most efforts at finding a cure focused on these abnormal structures. But a research team has identified alternate chemistry that could account for the various pathologies associated with the disease.
Scientists have completed a landmark study on how to save coral reefs in the Indian and Pacific Oceans.
A research team has mapped the molecular structure of an aggressive protein aggregate that causes acceleration of Alzheimer's disease.

The result of the 2016 US presidential election was, for many, a surprise lesson in social perception bias -- peoples' tendency to assume that others think as we do, and to underestimate the size and influence of a minority party. Many psychologists attribute the source of these biases to faulty cognitive processes like 'wishful thinking' or 'social projection,' but according to a new study, the...
Scientists have found a way to make single-celled bacteria behave like stem cells, differentiating into genetically unique individuals as they divide.
A breakthrough study has identified a specific antibody target implicated in neuropsychiatric symptoms of lupus. These symptoms, including cognitive impairment, mood disorders, seizures, headaches and psychosis, are among the most prevalent manifestations of the disease and occur in as many as 80% of adults and 95% of children with lupus.
Everywhere you go there are stormwater detention basins built near large construction projects intended to control the flow of rainwater and runoff. Now, those basins might help in controlling nitrogen runoff into rivers and lakes, according to civil and environmental engineers.
The thick scent of smoke hung in the midday air when a trail along the Kings River opened up to an ominous scene: flames in the trees and thick gray smoke shrouding canyon walls.
US President Donald Trump's administration on Monday finalized rollbacks to key provisions of the Endangered Species Act, a law supported by a large majority of Americans and credited with saving the gray wolf, bald eagle and grizzly bear.
Forecasters are warning of scorching heat across a wide stretch of the U.S. South and Midwest, where it will feel as high as 115 degrees (46 degrees Celsius) in some spots.
Russia's nuclear agency chief on Monday confirmed that five scientists killed last week were developing "new weapons" and vowed to continue testing "until the end," despite the explosion.
A mysterious explosion that killed five nuclear scientists on Russia’s northern frontier last week was caused by a nuclear power generator, Russia’s Rosatom state nuclear concern has said following reports the blast was related to a state-of-the art nuclear missile. Monitors in nearby Severodvinsk said they detected a temporary spike in radiation levels after the incident on Thursday,...
An increasing number of marine researchers say pink salmon, which are voracious eaters, are thriving at the expense of higher-value sockeye salmon, seabirds and other species with whom their diet...
Archaeologists in Pompeii have discovered a treasure trove of good luck charms and fertility amulets which they think may have been used for casting spells by an ancient Roman sorcerer. The collection includes tiny carved phalluses, pieces of bone shaped as human skulls and fists, small bronze bells which would have been rung to ward off bad luck, and scarab beetles made from amethyst. There are...
