The pain of downsizing extends far beyond laid off workers and the people who depend on their paychecks, according to a new UCLA-University of Michigan, Ann Arbor study.

Even a single involuntary displacement has a lasting impact on a worker's inclination to volunteer and participate in a whole range of social and community groups and organizations, found the study, which appears in the September issue of the international scholarly journal Social Forces.

Whether driving on the highway or walking down the street, we pick up on both deliberate signals and unconscious cues to predict what other people are going to do and act accordingly. But robots have trouble following each other around, for example, when a leader turns a corner and disappears from sight. Researchers at UC Davis have come up with a control system that allows a robot to pick up on cues that the leader is about to turn, predict where it is going and follow it.

The geysers of Yellowstone National Park owe their eistence to the "Yellowstone hotspot"--a region of molten rock buried deep beneath Yellowstone, geologists have found.

But how hot is this "hotspot," and what's causing it?

In an effort to find out, Derek Schutt of Colorado State University and Ken Dueker of the University of Wyoming took the hotspot's temperature.

The scientists published results of their research, funded by the National Science Foundation (NSF)'s division of earth sciences, in the August, 2008, issue of the journal Geology.

There have been many reports in the media about the effects of global warming on the Greenland ice-sheet, but there is still great uncertainty as to why there is an ice-sheet there at all.

Reporting today (28 August) in the journal Nature, scientists at the University of Bristol and the University of Leeds show that only changes in atmospheric carbon dioxide are able to explain the transition from the mostly ice-free Greenland of three million years ago, to the ice-covered Greenland of today.

(Santa Barbara, Calif.) – Two UC Santa Barbara astronomers are part of a team that has made a stunning discovery using the Hubble Space Telescope and Chandra X-ray Observatory, it was announced today by the National Aeronautics and Space Administration.

The capture of a collision of galaxy clusters was made by a team led by Marusa Bradac, a postdoctoral researcher and Hubble fellow in UCSB's Department of Physics. The international team also included Tommaso Treu, assistant professor of physics at UCSB.

Athens, Ga. – Most college students understand how they can prevent the transmission of HIV but are less knowledgeable about HIV testing, according to a new University of Georgia study.

Su-I Hou, associate professor in the UGA College of Public Health, surveyed more than 500 students and found that they scored higher on general questions related to HIV and AIDS (82 percent correct) than items specifically related to HIV testing (72 percent correct).

Despite investments, community goodwill and some good ideas, a vexing question remains in the age of school reform: Why has so much hope and effort led to disappointment?

Beginning in the late 1980s, the Chicago Public Schools, like many urban schools systems, launched a series of initiatives to reorganize schools, improve teaching and encourage parental participation. The changes in Chicago not always have met the expectations of proponents, wrote Charles Payne in his new book, "So Much Reform, So Little Change: The Persistence of Failure in Urban Schools".
