Chemists gain edge in next-gen energy: Flexible film can catalyze production of hydrogen

Posted: 04 Nov 2014 05:38 AM PST

Scientists have created a flexible film with the ability to catalyze the production of hydrogen or be used for energy storage. They have turned molybdenum disulfide's two-dimensional form into a nanoporous film that can catalyze the production of hydrogen or be used for energy storage.

Astronomers solve puzzle about bizarre object at center of our galaxy: Enormous black hole drove two binary stars to merge

The mystery about a thin, bizarre object in the center of the Milky Way that some astronomers believe to be a hydrogen gas cloud headed toward our galaxy's enormous black hole has been solved by astronomers.

Arctic warming: Scientists identify new driver

Posted: 03 Nov 2014 01:19 PM PST

A mechanism that could turn out to be a big contributor to warming in the Arctic region and melting sea ice has been identified by scientists. They found that open oceans are much less efficient than sea ice when it comes to emitting in the far-infrared region of the spectrum, a previously unknown phenomenon that is likely contributing to the warming of the polar climate.

String field theory could be the foundation of quantum mechanics: Connection could be huge boost to string theory

Posted: 03 Nov 2014 11:23 AM PST

Scientists propose a link between string field theory and quantum mechanics that could open the door to using string field theory as the basis of all physics. Their calculations "could solve the mystery of where quantum mechanics comes from," said a co-author.

Startling decline in European birds: Majority of losses from most common species

Posted: 02 Nov 2014 06:21 PM PST

Bird populations across Europe have experienced sharp declines over the past 30 years, with the majority of losses from the most common species, according to a new study. However numbers of some less common birds have risen.

Resveratrol could reverse benefits of being active

Posted: 01 Nov 2014 02:32 PM PDT

Adding resveratrol supplements to your exercise routine may not enhance the effects of physical activity, scientists say. "The easiest way to experience the benefits of physical activity is to be physically active," says Dr. Gurd, a professor in the School of Kinesiology and Health Studies. "The efficacy of resveratrol at improving metabolic and cardiovascular functions is not as profound as was once thought."

Three abrupt pulses of carbon dioxide during last deglaciation, study shows

Posted: 29 Oct 2014 11:56 AM PDT

The rise of atmospheric carbon dioxide that contributed to the end of the last ice age more than 10,000 years ago did not occur gradually, but was characterized by three 'pulses' in which carbon dioxide rose abruptly.

To reap the brain benefits of physical activity, just get moving

Posted: 29 Oct 2014 06:52 AM PDT

Everyone knows that exercise makes you feel more mentally alert at any age. But do you need to follow a specific training program to improve your cognitive function? Science has shown that the important thing is to just get moving. It's that simple.

New Evidence Puts Man In North America 50,000 Years Ago

Posted: 18 Nov 2004 07:40 AM PST

Radiocarbon tests of carbonized plant remains where artifacts were unearthed last May along the Savannah River in Allendale County by University of South Carolina archaeologist Dr. Albert Goodyear indicate that the sediments containing these artifacts are at least 50,000 years old, meaning that humans inhabited North American long before the last ice age.
