All females tracked for more than six months remained in the same foraging grounds, moving to deeper water for the winter where they conducted dives of up to a record breaking 10.2 hours. Five females were also tracked when they nested again up to five years later and returned to the sam...

Lower carbon dioxide emissions from coal-fueled power plants possible with technology development

...oward this development.? Rochelle spent the past six years developing the technology with funding from the U.S. Department of Energy and the Texas Advanced Technology Program. Like its commercial counterparts, his process captures carbon dioxide gas by dissolving it in a solution containing the chemica...

Meeting the ethanol challenge: Scientists use supercomputer to target cellulose bottleneck

...ar events required the simulations to run for some six million time steps over 12 nanoseconds (a nanosecond is one billionth of a second) in order to capture enough of the motion and shape changes of the enzyme as it interacted with the cellulose surface. This is an extremely long time in molecular t...

...t skeletal regions. MacFadden's team also analyzed six specimens from the Santa Fe River in north Central Florida. "We found that the Titanis fossils were 2 million years old and not 10,000 years old as had been suggested," MacFadden said. "This also shows the last known occurrence of Titanis in the fo...

Protein therapy may reduce infarct size in heart attack patients

...s and assessed safety and cardiac outcomes through six months. This trial was designed as an exploratory study to assess the potential impact of KAI-9803 in this “first-in-human?study. Results indicate that KAI-9803 may be associated with less myocardial necrosis with lower CK-MB AUC values at all do...

Swimming 'to the left' gets bacteria upstream, and may promote infection

...for this study. "Each cell normally has two to six flagella that can rotate together as a bundle and act as a propeller to drive the cell forward. Away from any boundaries, the cells swim in a straight line, but near a surface, opposing forces of flow and bacterial forward motion cause the bacteria t...
