Bats in flight reveal unexpected aerodynamics

...laser imaging device, which captures the position, speed and direction of the particles in her wake. By combining the information from dozens of flights, the research team was able to build a picture of the location and strength of the wake structure at each point in the bat's wing stroke. The detail of t...

However, in the neurons with mutant MFN2 genes, movement is significantly reduced. Still unknown is exactly how the mutated MFN2 protein alters mitochondrial transpo...

Environments resilient in the face of hurricanes, but questions remain, says journal special issue

...cteristics of the storms themselves: direction and speed of approach, point of landfall, and intensity all made a difference in the extent of environmental damage. Storms that carried more rainfall seemed to do more long-term damage than "hit-and-run" storms with higher winds. "The research compiled in t...

New study sheds light on 'dark states' in DNA

...Still, a picosecond is not so fast compared to the speed of some chemical reactions in living cells. In tests of single DNA bases, the dark state lasted for 10-150 picoseconds -- much longer than the bright state. The chemists reported their results in the Proceedings of the National Academy of Sciences. ...
