New research indicates a 'troubled' greenhouse is brewing

...k says these findings indicate it is unlikely that super storms will freeze North America and Europe, as depicted in the recent movie "The Day After." "During the greenhouse spike of 55 million years ago, tropical mangroves and rain forests spread as far north as England and Belgium and as far south as Ta...

Super predators and mass extinctions

...le community is disrupted when mutations lead to a super predator that quickly decimates the prey populatio... the mutation rate, the longer the periods between super predators. For a sufficiently low mutation rate, the model can lead to cycles that correspond to our...

To Stop Evolution: New Way Of Fighting Antibiotic Resistance Demonstrated By Scripps Scientists

...xperimental and potentially toxic drugs. Now some super bugs -- multiple drug-resistant bacteria -- are emerging as an even greater threat. Multiple drug-resistant TB is no longer susceptible to broad categories of antibiotics, such as rifampicin, isoniazid, and streptomycin. Some strains of the common ho...

World-first technology enables study of ancient bacteria

...duce methane that accumulates in "gas hydrates" ?a super concentrated methane ice that contains more carbon than all conventional fossil fuels and, therefore, a potentially enormous energy source. However, we know little about gas hydrates as they melt during recovery due to the fall in pressure. Professo...

Spinal cord bridge bypasses injury to restore mobility

The body's spinal cord is like a super highway of nerves. When an injury occurs, the body's policing defenses put up a roadblock in the form of a scar to prevent further injury, but it stops all neural traffic from moving forward. Researchers from Case Western Reserve University, Dr...

For super-obese patients, duodenal switch beats gastric bypass

...t and possibly the duration of weight loss." The super obese make up only a fraction of the U.S. obesity pandemic, but their ranks are increasing faster than any other group. When the term was coined in 1987, fewer than one in 2,000 adults in the United States met the criteria of a BMI greater than 50. ...

'Super' enzyme may lead way to better tumor vaccines

...su Park with doing much of the work to develop the super form of Akt1. Using specially designed adenoviruses, he and his colleagues put the modified "super" Akt1 molecule into the dendritic cells. "As predicted, these dendritic cells lived longer and were more potent, both in the laboratory and in mi...

Birth rate, competition are major players in hominid extinctions

...early members of the genus Homo who succeeded were super ecological opportunists," says Jablonski. "They would eat vegetation and scavenge, kill small animals and forage." Cultural adaptations helped these opportunists to take advantage of whatever food was available. But culture did not seem to help ...

Envisat captures first image of Sargassum from space

...eresting things, including Sargassum and Antarctic super blooms. It really gives us a new and unique view of the Earth." Gower and King are now combining data from MERIS with a sophisticated processing algorithm and powerful Grid computing to broaden this new view. The basic principle behind Grid compu...
