Unprecedented Antarctic ice calls for twice the normal icebreaking muscle
A variety of natural factors, including the presence of an enormous iceberg dubbed B-15A, caused the sea ice near McMurdo Station, the National Science Foundation's logistical hub in Antarctica, to be far more extensive and much thicker during the 2001-2002 research season than previously recorded in the history of the U.S.

New index developed by Yale researcher to assess the risk of mortality in an elderly population
In order to foster sound health care programs and policies concerning an aging population, a Yale researcher has devised a new index that forecasts which patients are most likely to die within one year after being discharged from the hospital.

Suicides involving guns rise sharply among young African-American males
Deaths from self-inflicted gunshot wounds are on the rise among young African-American males.

Martian surface features were eroded by liquid carbon dioxide, not running water, researchers say
Scientists have provided new evidence that liquid carbon dioxide, not running water, may have beeen the primary cause of erosional features such as gullies, valley networks, and channels that cover the surface of Mars.

Wolves decline, moose increase
A mild winter is behind the decline in the wolf population at Isle Royale National Park, home of a 44-year study of the predator-prey relationship between wolves and moose.

Cigarette ads target youth, violating $250 billion 1998 settlement

A Mayo Clinic study suggests that regular use of aspirin, ibuprofen and other nonsteroidal anti-inflammatory drugs (NSAIDs) may help protect against prostate cancer, the second leading cause of cancer death among men in the United States.

Research institutions, NCSA, HP join Gelato Federation
The University of Illinois at Urbana-Champaign and the National Center for Supercomputing Applications (NCSA) on the UI campus have joined Hewlett-Packard Co. and five other leading research institutions in the Gelato Federation, a worldwide consortium focused on enabling open source Linux-based Intel® Itanium™ Processor Family computing solutions for academic, government and industrial research.

Study succeeds in closing gaps in heart attack care
The results of a new study show there may be a way to close the huge gap between what has been proven to help heart attack victims, and what those patients actually receive.
