Like teachers who rap a ruler before announcing homework in noisy classrooms, Puerto Rican anole lizards perform eye-catching pushups before beginning head-bobbing displays that advertise their territory and status, according to a new study by researchers at the University of California, Davis.

Millions of older Americans stand at the epicenter of the current financial crisis and the implications must be confronted, said experts today during a symposium at The Gerontological Society of America's (GSA) 61st Annual Scientific Meeting.

Internet network performance problems are not only annoying to users -- they are costly to businesses and network operators. But since the Internet has no built-in monitoring system, network problems often go unnoticed.

To help fix this problem, researchers at the McCormick School of Engineering and Applied Science at Northwestern University have developed a new way to detect and report such problems in real time through their Network Early Warning System.

CHAMPAIGN, Ill. — Widespread layoffs that stem corporate financial losses but leave workers out in the cold would deepen the looming recession that sparked them, a University of Illinois labor expert warns.

Displaced workers with no paychecks or prospects could add a potentially catastrophic drag to a U.S. economy already facing its worst downturn in decades, says Joel Cutcher-Gershenfeld, the dean of the School of Labor and Employment Relations.

COLLEGE PARK, Md. -- The University of Maryland-led Milagro collaboration, comprised of scientists from 16 institutions across the United States, has discovered two nearby regions with an unexpected excess of cosmic rays.

Waltham, Mass--As the economy continues to reel, a new report finds that 4 million American households lost economic security between 2000 and 2006, and that a majority of America's middle class households are either borderline or at high risk of falling out of the middle class altogether. The new report, "From Middle to Shaky Ground: The Economic Decline of America's Middle Class, 2000-2006" was published by the policy center Demos and the Institute for Assets and Social Policy (IASP) at Brandeis University.

Racial prejudice in Britain has been declining sharply in Britain since the 1980s thanks to the greater tolerance of younger generations - according to a new study.

Dr Rob Ford from The University of Manchester says that social contact with black or Asian Britons is becoming increasingly unremarkable to white people in their 20s and 30s.

Research chemists at the University of Warwick have devised an elegant process which simply and cheaply covers small particles of polymer with a layer of silica-based nanoparticles. The final result provides a highly versatile material that can be used to create a range of high performance materials such as: self healing paints, and clever packaging that can be tailored to let precise levels of water, air or both pass in a particular direction.

Holiday shopping season has arrived, and tough financial times mean that more people will probably be shopping around for the best price. But a new study co-authored by North Carolina State University's Dr. Jonathan D. Bohlmann shows that shoppers who compare prices at multiple online retailers will not only find the best value, but will also likely contribute to driving down prices for that product at other retailers.

ANN ARBOR, Mich.---Slow-moving ocean and river currents could be a new, reliable and affordable alternative energy source. A University of Michigan engineer has made a machine that works like a fish to turn potentially destructive vibrations in fluid flows into clean, renewable power.

The machine is called VIVACE. A paper on it is published in the current issue of the quarterly Journal of Offshore Mechanics and Arctic Engineering.
