scan cyclic voltammetry technique that now allows the team to measure dopamine levels in the rats instantaneously some 200 times faster than has ever been done before. "We were among the first groups to fabricate the carbon-fiber electrodes, the fir...
Speedy elephants use a biomechanical trick to 'run' like Groucho

they are swimming, and the angle at which they are swimming. "This has been the best collaboration I have ever worked on," Zimmer said. "This is a perfect example of the importance of basic research. We were working with a marine animal; a group in G...
Human sperm may 'smell' their way to the egg, Science study suggests
...might be used in the future to find the motile and fast
sperm cells that are needed for fertilization." Further research is necessary before such approaches may be realized. The researchers also identified an antagonist compound, "undecanal" that appears to block the affect of bourgeonal and inhibits the ...
