UCSD study reveals how plants respond to elevated carbon dioxide

...e earplugs one would respond to the changes in the rhythms of the music," said Young. "Similarly, our findings suggest that carbon dioxide primes the calcium sensors to respond to the calcium spikes in the cell. Since changes in calcium concentration are used in other communication processes within cells, th...

Protein shown to rally biological clock

...s the brain’s biological clock to coordinate daily rhythms in behavior and physiology. The finding clarifies the roles that both VIP and a neurotransmitter GABA play in synchronizing biological clocks, and sheds light on how mammals, in this case mice and rats. regulate circadian rhythm. Results were pub...

Slow brain waves play key role in coordinating complex activity

...t. "When you stop reading and begin to type, theta rhythms oscillate in motor structures, allowing you to pla...ons. "This coupling is important because the two rhythms have different functions and operate on different spatial scales - a patch of high frequency activit...

Does missing gene point to nocturnal existence for early mammals?

...visual processes, such as regulating our day-night rhythms and pupil constriction." Although the melanopsin gene is present in all vertebrates, the version in mammals was unusually different to that found in fish, amphibians and birds. "At first, we put this genetic anomaly between mammals and other ve...

Surgeons develop simpler way to cure atrial fibrillation

...tients, medications can control the abnormal heart rhythms and the risk of clotting associated with atrial fibrillation, but unlike the Cox-maze procedure, the drugs do not cure the disorder. Damiano says their most recent study of Cox-maze IV is unique because the surgeons carefully matched the age, sex ...

'Night owls' report more insomnia-related symptoms

...uld investigate the relationship between circadian rhythms and insomnia, especially with the severity of the ‘night owl?group,?said Ong. “These factors may serve to perpetuate the insomnia disorder, and might be particularly important to consider when treating this subgroup of insomniacs.? Insomnia, a cla...

Prenatal Stress Keeps Infants, Toddlers up at Night, Study Says

... signaling system helps to properly regulate daily rhythms of waking, sleeping, even hunger that is, if its formation has not been disrupted. This could explain why sound sleep doesnt come easily to kids whose signaling systems may not be properly calibrated, OConnor said. However, more research is need...
