Scientists reveal structure of gateways to gene control

...per by Pugh's team marks the leading edge of a new wave of anticipated discoveries about gene regulation, made possible by recently developed laboratory equipment for high-volume, or massively parallel, DNA sequencing. "Traditional DNA sequencing methods processed one DNA strand at a time, but now we can...

Satellites shed light on global warming

...study by Canadian researchers that shows planetary wave speed is expected to increase considerably during this century as a side effect of climate change induced warming of the oceans, which may have a number of far-reaching effects on ocean dynamics. "It is no surprise, then, that scientists are eage...

Study finds surfing safer than soccer

Chronic fatigue syndrome impairs a person's slow wave activity during sleep

...) has been associated with altered amounts of slow wave sleep, which could reflect reduced electroencephal...ds that CFS is also associated with a blunted slow wave activity (SWA) response to sleep challenge, suggesting an impairment of the basic sleep drive and ho...

Mice with a migraine show signs of brain damage

...ce of the brain, followed by a gradually spreading wave of suppressed brain cell activity. Many scientists believe that the phenomenon contributes to injury from stroke and from traumatic brain injury as well as migraine. While it’s been widely recognized that CSD underlies some migraines, Nedergaar...

Experts predict Tamiflu could halve the pandemic influenza death toll versus no intervention

...hed to the strain will be available in the initial wave of a pandemic.” Prophylaxis with antivirals or vaccines Vaccination is the primary means of preventing influenza. However, at the beginning of a pandemic, supplies of vaccines which are fully matched to the pandemic strain will be limited or...

Nicotine rush hinges on sugar in neurons

...ne, Chen said. But the molecular basis of such a wave in nAChR or any other protein has not been clearly established. Instead, the Chen group’s study of crystal structure suggested a simple mechanical role for sugar molecules attached to the surface of the receptor. “They serve as the link between t...
