Study of breast cancer in black womenA new study seeking to improve scientists' understanding of breast cancer, including why the disease's fatality rate is higher in African-American women, is getting underway in 44 counties in North Carolina.
The project, named after the late Jeanne Hopkins Lucas, a North Carolina state senator who died of breast cancer last year, is being run by the Lineberger Comprehensive Cancer Center at the University of North Carolina at Chapel Hill.

Personality shapes perception of romancePersonality scientists have long known that people who report they have certain personality traits are also more (or less) likely to be satisfied with their romantic partners. Someone who says she is often anxious or moody, for example, is more likely than her less neurotic counterpart to be dissatisfied with her significant other.
In a new analysis, scientists at the University of Illinois observed that measuring the quality of romantic........Go to the Society medical news blog (Added on 10/31/2008 5:28:38 AM)
Type-1 diabetes not so much bad genesInvestigators combing the genome in the hope of finding genetic variants responsible for triggering early-onset diabetes may be looking in the wrong place, new research at the Stanford University School of Medicine suggests.
Early-onset diabetes, also known as type-1 diabetes, is an autoimmune disease, caused when the immune system attacks and destroys insulin-producing cells in a person's pancreas.
