New understanding of jet lag

... clock." He suggested that the differing rates of synchronization that occurs in the central clock may be part of a complex evolutionary adaptation to seasonal light changes, but the mechanism, in effect, becomes confused when confronted with unnatural and dramatic shifts in light schedules. The research is part o...

Carnegie Mellon U. transforms DNA microarrays with standard Internet communications tool

...," said Bar-Joseph. The new method also overcomes synchronization loss, a vexing problem for scientists who study hundreds or thousands of cells over time, according to Bar-Joseph. Large groups of living cells that start out together at the same biological point in time eventually become asynchronized in their acti...

Carnegie Mellon researchers discover key deficiencies in brains of people with autism

...evious studies have demonstrated a lower degree of synchronization among activated brain areas in people with autism,...h shows for the first time that the abnormality in synchronization is related to the abnormality in the cabling. The results suggest that the connectivity among brain ...

Electronic chip, interacting with the brain, modifies pathways for controlling movement

...ngthening may have been produced by the continuous synchronization of activity at the two sites, generated by the recurrent brain-computer interface. Timing is critical for creating these connections, the researchers said. The conditioning effect occurs only if the delay between the recorded activity and the stimu...

Circadian gene helps the brain predict mealtime

...ht. The researchers found that, interestingly, synchronization of timing between organs by scheduled meals is not affected by the Period 2 mutation, indicating that this gene is not crucial for scheduled food availability to affect the physiological coordination of tissues outside the central nervous system. ...

Theory of oscillations may explain biological mysteries

...teractions such as predation and competition. Such synchronization can have far-reaching effects. Vandermeer suggests that several well-known biological conundrums, such as the higher-than-expected diversity of plankton in aquatic ecosystems, may be explained this way. Physicists know that even a weak coupling betw...

Penn study on olfactory nerve cells shows why we smell better when we sniff

...zed with inhaling. "The driving force for such synchronization remained a mystery for more than 50 years," says senior author Minghong Ma, PhD, Assistant Professor of Neuroscience. "These results help us understand how the mammalian olfactory system encodes and decodes odor information in the environment." Re...
