Study investigates 'divorce' among Galapagos seabirds
...s to the fledgling. So, if, when mating season rolls
around again, a male looks a little ragged from taking care of junior, his mate is likely to choose another. A male’s capacity to raise offspring, a quality that can vary with time, may carry more weight with a mate than stellar genes or past breedi...
Cells selectively absorb short nanotubes
...SWCNTs are tiny cylinders—essentially single-sheet rolls
of carbon atoms. They are many times stronger than steel and possess superlative thermal, optical and electronic properties, but safety and biocompatibility remain an open question. "Published data citing in vitro (outside the body) toxicity are ...
The biggest bug in gut discomfort
...chool of Medicine report that C. jejuni apparently rolls
in on the cell’s regular endocytic pathway but quickly exits, heading off-road for its own network of intracellular hideouts. These C. jejuni-filled vacuoles make their own way toward the nucleus, taking up strategic positions near the cell’s transpo...
Avian flu modeled on supercomputer, explores vaccine and isolation options for thwarting a pandemic
...ecome transmissible human-to-human. The simulation rolls
out a city- and census-tract-level picture of the spread of infection through a synthetic population of 281 million people over the course of 180 days, and examines the impact of interventions, from antiviral therapy to school closures and travel res...
Computers close in on protein structure prediction
...e into their lowest energy state, like a ball that rolls
down a hill until it comes to rest on level ground. The energies of hundreds of thousands of possible shapes generated by the computer are computed, and the lowest energy shape is selected as the prediction. The prediction process happens in two ste...
