Computer analyses of global climate have consistently overstated warming in Antarctica, new research concludes. The study can help scientists improve computer models and determine if Earth's southernmost continent will warm significantly this century, a major research question because of Antarctica's potential impact on global sea-level rise.

Computer analyses of global climate have consistently overstated warming in Antarctica, concludes new research by scientists at the National Center for Atmospheric Research (NCAR) and Ohio State University. The study can help scientists improve computer models and determine if Earth's southernmost continent will warm significantly this century, a major research question because of Antarctica's potential impact on global sea-level rise.

The Arctic has become a poster child for the negative effects of climate change, but new research from the University of Washington shows that species living in the tropics likely face the greatest peril in a warmer world.

Polar bears fighting for survival in the face of a rapid decline of polar ice have made the Arctic a poster child for the negative effects of climate change. But new research shows that species living in the tropics likely face the greatest peril in a warmer world.

Scientists confirm computer model predictions that oxygen-depleted zones in tropical oceans are expanding, possibly because of climate change.

An international team of physical oceanographers including a researcher from Scripps Institution of Oceanography at UC San Diego has discovered that oxygen-poor regions of tropical oceans are expanding as the oceans warm, limiting the areas in which predatory fishes and other marine organisms can live or enter in search of food.

"Legacy: The Life of Nikola Tesla" by Norma Brody is an account of a relatively little known scientific giant.

In Legacy: The Life of Nikola Tesla, author Norma Brody chronicles the amazing life and times of the scientist who brought alternating current to America.

Physicist and astronomer Milo Wolff attempts to turn physics on its head with his theories on quantum waves, matter and space.

American physicist-astronomer Milo Wolff's newest release is Schrödinger's Universe, a book that takes readers on an adventure to discover the mystery behind quantum waves, matter, and space. This reader-friendly journey into the physics of our Universe bridges the work of revolutionary physicists from 1845 to Wolff's discoveries today, as it takes us beyond current scientific dogma to an expanded understanding of our physical world, natural laws, and the real truth about our interconnectedness.

Jonathan Sawyer spent $30 000 - and voided the warranty - to add a plug to his Prius hybrid.

Jonathan Sawyer wants to do his part for the environment--and then some. His roof is covered with solar panels, and he has a wind turbine as well. A decade ago he was one of the few people to lease a General Motors EV1, even though GM didn't sell them in Colorado, where Sawyer lives. Later, he bought an all-electric Toyota, the RAV4 EV. So it should come as no surprise that for Sawyer an off-the-line Prius hybrid isn't quite green enough. What he did about it, though, was remarkable.

Bison can repopulate large areas from Alaska to Mexico over the next 100 years provided a series of conservation and restoration measures are taken, according to continental assessment of this iconic species by the Wildlife Conservation Society and other groups.

Bison can repopulate large areas from Alaska to Mexico over the next 100 years provided a series of conservation and restoration measures are taken, according to continental assessment of this iconic species by the Wildlife Conservation Society and other groups. The assessment was authored by a diverse group of conservationists, scientists, ranchers, and Native Americans/First Nations peoples, and appears in the April issue of the journal Conservation Biology.

The definition of "organic" is defined by U.S. Department of Agriculture; "natural," however, can be defined differently depending on who's doing the labeling. But both terms mean one thing: higher costs for producers. That's why Ben Wileman hopes that his research will be another tool to help those in the beef industry pondering whether to abandon conventional methods and go natural or organic.

When Kansas State University graduate student Ben Wileman was a practicing veterinarian in Belle Fourche, S.D., natural and organic labels were a big focus for the beef producers he saw.

As arctic ice disappears, the remaining ice becomes more vulnerable to solar radiation, according to a study funded by NASA and the National Science Foundation.

The shrinking expanse of Arctic sea ice is increasingly vulnerable to summer sunshine, new research concludes. The study, by scientists at the National Center for Atmospheric Research (NCAR) and Colorado State University (CSU), finds that unusually sunny weather contributed to last summer's record loss of Arctic ice, while similar weather conditions in past summers do not appear to have had comparable impacts.
