New Five-Quarked Baryon State

Strong evidence for a new five-quark baryon state (known as a pentaquark) has been reported by a team of physicists known as the CLAS Collaboration working at the Thomas Jefferson National Accelerator Facility (Jefferson Lab) in Virginia. Link

Decline in child-centeredness in American society

There is a growing disconnect between American children and marriage — society’s chief child-rearing institution — according to the latest report by the National Marriage Project at Rutgers, The State University of New Jersey. Fewer children are living in married-couple households and fewer married couples families have children compared to past decades, according to “Marriage and Children: Coming Together Again?” from “The State of Our Unions 2003,” a report issued annually by the National Marriage Project.

Seniors’ Memories Might Not Be So Bad, After All

Forget everything you’ve heard about forgetfulness. Researchers at North Carolina State University believe that age-related declines in memory and cognitive functioning may not be as pronounced as once believed. Dr. Thomas Hess, professor of psychology at NC State, says pessimistic notions of changes in mental abilities associated with growing older may in part be attributed to how early studies into cognition and aging were conducted. His findings were outlined in a recent edition of the Journal of Gerontology and chronicled in Science magazine. Hess’ research is part of a three-year study into stereotype threat, aging and memory as part of a $403,000 grant from the National Institute on Aging.

Common pain relief drug may improve skin cancer tretment

Researchers from Ohio State University found that a common pain relief medication seems to increase the effectiveness of a drug used to treat skin cancer. Experiments in mice showed that the combination of celecoxib — a prescription-only non-steroidal anti-inflammatory drug (NSAID) — and a cream commonly used to treat nonmelanoma skin cancer was up to 35 percent more effective in reducing the number of skin cancer tumors than treating such lesions with the cream alone.

Human Interference May Have Caused SARS To Jump Species

In the last few months, severe acute respiratory syndrome has infected thousands in Asia, traveled to various parts of the world and gained international attention. In April 2003, the disease was conclusively identified as a type of coronavirus unlike any other known human or animal virus in the Coronavirus family.
Sanjay Kapil, a Kansas State University associate professor of diagnostic medicine pathobiology, says human interference with domestic and wild animals could be a factor in the development of the disease.
Samples of the pathogens identified in severe acute respiratory syndrome look similar to coronaviruses found in animals. Because the sequences found in human samples are unique, the virus must have changed substantially when it transferred from animals to humans, Kapil said.

Liberty Bell passes stress test

How do you move a wounded, 2,080-pound patriot? Very carefully. Recently, under the watchful eyes of curators, conservators, surveyors, and engineers, a team of riggers deftly lifted the fragile Liberty Bell off of the supports on which it has been resting for a quarter century and confirmed the Bell can be safely moved into its new home this fall.
