Researchers at Brigham and Women's Hospital have developed a genetic model that is yielding new insights into what happens when astrocytes go awry.
A larger portion of Africa is currently at high risk for malaria transmission than previously predicted, according to a new University of Florida mapping study.
Using statistically modeled maps drawn from satellite data and other sources, US Geological Survey scientists have projected that the near-surface permafrost that presently underlies 38 percent of boreal and arctic Alaska would be reduced by 16 to 24 percent by the end of the 21st century under widely accepted climate scenarios.
Researchers for the first time have attempted to measure all the material leaving and entering a mountain range over more than a million years and discovered that erosion caused by glaciation during ice ages can, in the right circumstances, wear down mountains faster than plate tectonics can build them.
Recent conversations in the United States have centered on discrimination issues; yet, little is known about how discrimination affects youths' mental health and their willingness to help others. Now, University of Missouri researchers found Latino immigrant youth who reported feeling discriminated against had more depressive symptoms and were less likely to perform altruistic behaviors six months and a year after experiencing discrimination.
Taking the pregnancy hormone estriol along with their conventional medications helped patients with relapsing-remitting multiple sclerosis avoid relapses.
Changing labor laws -- with some states curtailing collective bargaining -- may weaken political participation by teachers and other public employees, traditionally cornerstones in electing Democrats, a Baylor study finds.
Individuals with autism spectrum disorder (ASD) often have difficulty recognizing and interpreting how facial expressions convey various emotions -- from joy to puzzlement, sadness to anger. This can make it difficult for an individual with ASD to successfully navigate social situations and empathize with others.
The rising atmospheric concentration of CO2 is beneficial for the physiology of sorghum, an economically and nutritionally important crop grown worldwide. This is the conclusion of a study performed at the University of São Paulo in Brazil. The researchers found that when this plants were kept in a low-humidity environment, CO2 not only protected them against drought but also promoted a systemic adjustment in their metabolism that led their seeds to accumulate 60 percent more protein.
Researchers determine that marine fish are influenced by the food supply upon which they depend and competition for those resources.
