Fishing for a 'balanced harvest' can achieve productive fisheries as well as environmental conservation, an international scientific team reports today in the journal Science.
Researchers from Canterbury Christ Church University have found that smokers are more likely to stop because of anti-social attitudes towards them than from fear of ill-health.
Worldwide increases in the incidences of asthma, allergies, infectious and cardiovascular diseases will result from a variety of impacts of global climate change, including rising temperatures, worsening ozone levels in urban areas, the spread of desertification, and expansions of the ranges of comm...
Long thought to produce only one generation of tree-killing offspring annually, some populations of mountain pine beetles now produce two generations per year, dramatically increasing the potential for the bugs to kill lodgepole and ponderosa pine trees, University of Colorado Boulder researchers ha...
Princeton University researchers have used a novel virtual reality and brain imaging system to detect a form of neural activity underlying how the brain forms short-term memories that are used in making decisions.
A study by researchers at the University of California, San Diego School of Medicine and The University of Minnesota indicates that a parent's weight change is a key contributor to the success of a child's weight loss in family-based treatment of childhood obesity. The results were published today i...
A novel type of sensor, based on nanometer-scale pores in a semiconductor membrane, is a step closer to practical use in applications such as analyzing the protein contents of a single cell. Researchers pioneering single-molecule nanopore sensor technology at the Technische Universität München...
A study that examines a new type of silicon-carbon nanocomposite electrode reveals details of how they function and how repeated use could wear them down. The study also provides clues to why this material performs better than silicon alone. With an electrical capacity five times higher than convent...
Early snow melt in the Colorado Rocky Mountains initiates two chains of events resulting in population decline in the mormon fritillary butterfly, Speyeria mormonia. One effect of snow melt date was readily detectable, but the second, cryptic effect required an understanding of the butterfly's biolo...
The mild winter of 2012 has many people asking, "Where's the snow?" These two snow cover maps show the difference between snow extent on March 3, 2011, and March 5, 2012. The maps were compiled from data collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard NASA's ...
The seas are creeping higher as the planet warms. But how high will they go? Projections for the year 2100 range from inches to several feet, or more. The sub-tropical islands of Bermuda and the Bahamas contain important sites where researchers have gone looking for answers; by pinpointing where sho...
The Fish and Wildlife Service has approved a first-time permit allowing a Native American tribe in Wyoming to kill two bald eagles in a centuries-old religious ceremony once outlawed by the federal Bureau of Indian Affairs.
