Tasimelteon Reduces Transient Insomnia After Acute Sleep-Time Shift
from Medscape Medical News
Randomized trial results with tasimelteon, a melatonin agonist, suggest that the still-investigational agent improves sleep initiation and maintenance in concert with an acute shift in endogenous circadian rhythms after an abrupt advance in sleep time. The findings suggest that tasimelteon might be useful in treating transient insomnia associated with circadian-rhythm sleep disorders, such as that caused by jet lag or in night-shift work, the researchers conclude.

Poor Children's Brain Activity Resembles that of Stroke Victims
from Science Daily
University of California, Berkeley, researchers have shown for the first time that the brains of low-income children function differently from the brains of high-income kids. Brain function was measured by means of an electroencephalograph – basically, a cap fitted with electrodes to measure electrical activity in the brain – like that used to assess epilepsy, sleep disorders and brain tumors.
