Difference in fat storage may explain lower rate of liver disease in African-Americans
DALLAS March 27, 2009 Where different ethnic groups store fat in their bodies may account for differences in the likelihood they'll develop insulin resistance and non-alcoholic fatty liver disease, researchers at UT Southwestern Medical Center have found. According to research reported in th...Study finds a high rate of asthma in college athletes
COLUMBUS, Ohio More than a third of college athletes assessed for breathing problems had test results suggesting exercise-induced asthma, even in those athletes who had no previous history of asthma, a new study shows.

The thickness of sea ice in large parts of the Arctic declined by as much as 19% last winter compared to the previous five winters, according to data from ESA's Envisat satellite. Using Envisat radar altimeter data, scientists from the Centre for Polar Observation and Modelling at University Co...HPV DNA test identifies cervical pre-cancerous disease in developing countries with 90% success rate
Results of the first study to determine the accuracy of a new rapid screening test for HPV (Human Papilloma Virus), created specifically for use in the developing world, have shown it to be 90 per cent accurate in detecting precancerous cervical disease when tested on a group of local women in Sha...Microbes churn out hydrogen at record rate
By adding a few modifications to their successful wastewater fuel cell, researchers have coaxed common bacteria to produce hydrogen in a new, efficient way.

New York City’s smoking rate has plummeted since a comprehensive program against smoking was launched in 2002, according to findings issued today in the national Centers for Disease Control and Prevention’s Morbidity and Mortality Weekly Report (MMWR).

Armed with more than a decade’s worth of statistics, researchers are sounding a new alarm about growing rates of syphilis among gay and bisexual men. The overall number of syphilis cases in the United States fell from 50,578 in 1990 to just 7,177 in 2003 perhaps because of a nationwide prevention...More kidney cancer is detected and treated early, yet death rate rises
The number of cases of kidney cancer has been rising over the last two decades, and new research from the University of Michigan Comprehensive Cancer Center shows that this increase is driven largely by the detection of small, presumably curable, kidney masses. But even though the rising incidence ...US infant mortality rate fails to improve
Nearly 28,000 babies died before their first birthday, according to new infant mortality statistics for 2003 released by the National Center for Health Statistics (NCHS). The infant mortality rates showed no significant improvement in 2003 after increasing in 2002 for the first time since 1958. ...St. Jude projects 90 percent cure rate for ALL
The cure rate for the once almost universally fatal childhood cancer acute lymphoblastic leukemia (ALL) could reach 90 percent in the near future, thanks to improvements in diagnosis and treatment over the past four decades, according to investigators at St. Jude Children's Research Hospital.
