Neural bottleneck found that thwarts multi-tasking

...limitations and in finding where in the brain this bottleneck might be taking place." The research is particu...ing tasks at once." Identifying the information bottleneck responsible for this dual-task limitation required the use of functional magnetic resonance imaging,...

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

... cellulose remains slow and expensive. The central bottleneck is the sluggish rate at which the cellulose enzyme complex breaks down tightly bound cellulose into sugars, which are then fermented into ethanol. To help unlock the cellulose bottleneck, a team of scientists has conducted molecular simulations at t...

Scientists get best look ever at water-life connection

...he way of proteins trying to meet -- it would be a bottleneck in the process. And if it moved too fast, it couldn't connect with the protein at all. So I think this is nature's way of getting the interaction just right." ...

Researchers find docking sites for glucocorticoid receptor and Hsp90

...cademy of Sciences, also uncorks an almost 15-year bottleneck in research caused by difficulties in deciphering the actions of a heat-shock protein known as Hsp90. Hsp90 belongs to a family of proteins called chaperones that help other proteins achieve and maintain their 3-D structure. Unlike most chaperones...

Scientists make first step towards 'holy grail' of crystallography

...on of high quality crystals has long posed a major bottleneck for X-ray crystallography. This problem has become increasingly acute with the advent of structural genomics and proteomics which aim to determine the structures of thousands of proteins. Protein crystallography plays a major role in this understandi...

Ancient DNA provides clues to the evolution of social behavior

...uch more detailed information. ''You can't get the bottleneck time or the bottleneck size without both modern and ancient DNA,'' Chan explains. Social evolution Determining how the ...

Discovery of new molecular tools for biosynthesis could lead to advances in use of pectin

... the molecular tools to begin to break through the bottleneck of our understanding of pectin synthesis," Bacic said. ...

Picking particles faster than one at a time

... to choose hundreds of thousands of particles is a bottleneck in the process of single-particle reconstruction." Automatic particle-picking methods have been devised to meet this challenge, but until now even the best yield more than 30 percent false positives -- either poor-quality images of particles or som...

Health of coral reefs detected from orbit

...ll Resolution covers the world every three days, a bottleneck for global monitoring could be data processing," Dekker concludes. "However satellite sensors measuring sea surface temperature such as Envisat's Advanced Along Track Scanning Radiometer (AATSR) can be applied to prioritise reefs that are subject to ...

Institute for Systems Biology Symposium Addresses Need for Better Computational Tools

...se proteins of unknown function remains a critical bottleneck for systems biology and is crucial to understanding the biological relevance of genome-wide changes in mRNA and protein expression, protein-protein and protein-DNA interactions. World Community Grid is enabling ISB researchers to predict three dimen...
