...d that interfering with Dasm1 function drastically decreased
AMPA receptor function. Their experiments also revealed that Dasm1 was responsible for "awakening" silent synapses and promoting the maturation of the neuronal connections, a process that depends on dendrite development. "While we expected that Das...

Why your knees and quads hurt more after running than walking: You're only human

activation duration on energy cost, when humans increase speed and change gait from a walk to a run, remains an important challenge to sort out." The researchers conclude that "greater energy cost during running in humans may be explained in part by ...
Genetically-engineered 'marathon mouse' keeps on running
...PPAR-delta increased fat burning and, as a result, decreased
fat-tissue mass," said Evans. "Going into this experiment, the possibility of an effect on muscle fibers was not on our radar screen." However, when the researchers produced mice with enhanced PPAR-delta activity, they saw a major transformation in ...
