New understanding of jet lag

...uickly move back into harmony. The symptoms of jet lag would then be reduced or eliminated. "The key here is, we now know what the 'rubber band' is: the neurotransmitter GABA that ultimately brings the clock back into synch," Block said. "This could lead to future therapies for jet lag. This is the firs...

Travelers can avoid jet lag by resetting their body clocks

...er drug melatonin -- allows travelers to avoid jet lag by resetting their circadian body clock before cro... for a few days before flying would reduce the jet lag experienced upon arrival at the destination. The more days a person follows this procedure the less ...

Plant-derived vaccines safeguard against deadly plague

...The approach also eliminates the typical year-long lag time necessary to establish and characterize genetically modified, or transgenic plants. The beauty of system is its potential versatility that can be adapted to fight against other pathogens as well. The research team's next step is to refine th...

Alaska seal pup diet may hold key to decline of population

...of which diet group they were put in, continued to lag behind in weight gain and even lost blubber depth. "Our longitudinal study is leading to a better understanding of the role that fat consumption plays in the life of the harbor seal and could tie the declining population of seals and other marine ma...

New fruit fly protein illuminates circadian response to light

...esponse to light. The human condition known as jet lag takes place during the period when the body is attempting to resynchronize to the environmental light changes brought on by travel, namely from one time zone to another. A mutant fruit fly that possesses jetlag-like behaviors enabled senior author A...

High hourly air pollution levels more than double stroke risk

...atty deposits. This is possibly because the time lag between the start of this type of stroke and death is rather longer than that for a bleed into the brain, say the authors. Pervious research shows that the effects of air pollution act quickly on the body, say the authors, with inhaled particles det...

New dyslexia theory blames 'noise'

... States showing that infants with dyslexic parents lag behind their peers in forming categories for speech sounds. In the conclusion to their study in Psychological Science, the authors speculate that the deficit in noise exclusion may have biochemical roots in abnormal levels of GABA, a neurotransmi...

Chronic jet-lag conditions hasten death in aged mice
