The hormone of darkness: melatonin could hurt memory formation at night

11-15-2007 · EurekAlert!

In a study with zebrafish (Danio rerio), Gregg W. Roman, assistant professor in the Department of Biology and Biochemistry at the University of Houston, has found that melatonin directly inhibits memory formation at night. He describes his team's findings in a paper titled "Melatonin Suppresses Nighttime Memory Formation in Zebrafish," appearing in Science, the world's leading journal of original scientific research.

To understand the big picture, give it time -- and sleep
04-20-2007 · EurekAlert!
Memorizing a series of facts is one thing, understanding the big picture is quite another. Now a new study demonstrates that relational memory -- the ability to make logical "big picture" inferences from disparate pieces of information -- is dependent on taking a break from studies and learning, and even more important, getting a good night's sleep.

01-09-2007 · EurekAlert!
New measurements for three planets outside our solar system indicate their temperatures remain fairly constant -- and blazing hot -- from day to night, even though it is likely one side of each planet always faces its sun and the other is in permanent darkness.

Cellular killer also important to memory
12-21-2006 · EurekAlert!
A protein that triggers apoptosis also plays a part in memory formation. Graham R. Huesmann, a lead researcher on the study at the University of Illinois at Urbana-Champaign, had an intuition that growth and memory are linked. "You can't have growth without death," said David F. Clayton, a co-author of the study.

Research from the University of Michigan Health System suggests that hormone therapy might help women retain certain memory functions. In a study in the new issue of the Journal of Clinical Endocrinology & Metabolism, they report that a group of postmenopausal women showed more brain activity during a visual memory test than did women who were not taking the hormone therapy.

Bats prey on nocturnally migrating songbirds
02-13-2007 · EurekAlert!
It was until now believed that nocturnally migrating songbirds, while venturing into the unfamiliar night sky for accomplishing their long, challenging transcontinental migrations, could at least release anti-predator vigilance thanks to the concealment of darkness. A new study by Spanish and Swiss scientists -- published this week in PLoS ONE -- shows that migration at night is not without predation risk for passerines.

Cicardian system suffers and protects from prenatal cocaine exposure
07-10-2007 · EurekAlert!
Researchers from Boston University School of Medicine have shown that prenatal cocaine exposure in zebrafish (which share the majority of the same genes with humans) can alter neuronal development and acutely dysregulate the expression of circadian genes and those affecting melatonin signaling, growth and neurotransmission. The circadian factors, including the principal circadian hormone melatonin, can attenuate the prenatal effects of cocaine. These findings appear in the July 11 issue of the journal PLoS ONE.
