COLUMBIA, Mo. Katydid (or didnt she?) respond to the mating call of her suitors. According to scientists at the University of Missouri, one species of katydid may owe its ecological success and expanded habitat range to the ability of male katydids to adjust their mating calls to attract females.
Irvine, Calif. — Short-term stress lasting as little as a few hours can impair brain-cell communication in areas associated with learning and memory, University of California, Irvine researchers have found.
It has been known that severe stress lasting weeks or months can impair cell communication in the brains learning and memory region, but this study provides the first evidence that short-term stress has the same effect. The study appears in the March 12 edition of the Journal of Neuroscience.
Researchers from the University of Illinois at Chicago College of Medicine have discovered that a change in the location of a protein in the brain could serve as a biomarker for depression, allowing a simple, rapid, laboratory test to identify patients with depression and to determine whether a particular antidepressant therapy will provide a successful response.
The research is published in the March 12 issue of the Journal of Neuroscience.

MADISON - The pending federal decision about whether to protect the polar bear as a threatened species is as much about climate science as it is about climate change.
The U.S. Fish and Wildlife Service (FWS) is currently considering a proposal to list the polar bear as a threatened species under the Endangered Species Act, a proposal largely based on anticipated habitat loss in a warming Arctic.
MADISON - Researchers at the University of Wisconsin School of Medicine and Public Health (SMPH) are wagging a finger at currently held notions about the way digits are formed.
Studying the embryonic chick foot, the developmental biologists have come up with a model that explains how digits grow and why each digit is different from the others.
(PHILADELPHIA) At a time when several U.S. health insurers have discontinued payment for use of the sedative propofol during most screening colonoscopies, physicians at the University of Pennsylvania School of Medicine have discovered that an alternative way to administer the drug could both save millions of health care dollars and provide a safer way to deliver optimal pain relief.
Bogotá, Colombia, March 11, 2008—After 14 years without having been seen, several young scientists supported by the Conservation Leadership Programme (CLP), have rediscovered the Carrikeri Harlequin Frog (Atelopus carrikeri) in a remote mountainous region in Colombia.
March 11, 2008 (Oakland, Calif.) Findings in the Journal of the American Medical Association on the largest weight loss maintenance study to date reinforce Kaiser Permanentes approach to obesity prevention. The combination of both personal contact and web-based support are identified as the key to successful, long-term weight management. Kaiser Permanentes Center for Health Research in Portland, Ore., was the coordinating center for the Weight Loss Maintenance Trial of 1,032 overweight and obese adults and provided five of the study co-authors.
Researchers at the Johns Hopkins Kimmel Cancer Center have teased out two distinct sets of risk factors for head and neck cancers, suggesting that there are two completely different kinds of the disease.
