Aging :: New light on aging process
Scientists in Hong Kong have shed new light on why cell repair is less efficient in older people after a breakthrough discovery on premature aging, a rare genetic disease that affects one in four million babies.

Alzheimer’s Disease :: Behavior approach helps Alzheimer’s patients sleep
Behavioral techniques that are known to improve sleep in non-demented institutionalized older adults may benefit patients with Alzheimer’s disease who have nighttime insomnia, according to the findings of a small study published in the Journal of the American Geriatrics Society.
Heart Disease :: Isolated men having high blood marker linked to cardiovascular
Men who are socially isolated have elevated levels of a blood marker for inflammation that?s linked to cardiovascular disease, according to data from the Framingham Heart Study presented at the American Heart Association?s 45th Annual Conference on Cardiovascular Disease Epidemiology and Prevention.
Skin Cancer :: Antioxidant mixture improve protection against skin cancer
Despite the availability of topical sunscreens, skin cancer is on the rise. A group of chemists at University of Scranton in Pennsylvania says that adding a mixture of antioxidants to sunscreen may help enhance its protection. In animal studies, they found that a mixture of various topical antioxidants was more effective than single antioxidants in preventing the formation of skin tumors induced by ultraviolet light.
Obesity :: Obesity associated with colorectal cancer
Obesity is associated with an increased risk of colorectal cancer.
HIV :: Human Cells Can Silence HIV Genes – RNA silencing
For the first time, scientists have shown that humans use an immune defense process common in plants and invertebrates to battle a virus. The new finding that human cells can silence an essential part of HIV?s genetic make-up could have important implications for the treatment of people infected with the virus. Led by Kuan-Teh Jeang, M.D, Ph.D., of the National Institute of Allergy and Infectious Diseases (NIAID), part the National Institutes of Health, the researchers published their findings in this week?s issue of the journal Immunity.
Exercise :: Get off the computer and out to exercise in your free time
Do you – like millions of full-time workers – surf TV channels, play video games or boot up the computer in what little free time you have? If so, there?s a good chance you?re skimping on heart-healthy physical activities, scientists report at the American Heart Association?s 45th Annual Conference on Cardiovascular Disease Epidemiology and Prevention.
Depression :: Depression gene increase susceptibility to anxiety and depression
A brain scan study suggests that a suspect gene may increase susceptibility to anxiety and depression by weakening a circuit for processing negative emotion. People with the depression-linked gene variant showed less gray matter and weaker connections in the mood-regulating circuit. How well the circuit was connected accounted for nearly 30 percent of their anxious temperament, researchers at the National Institute of Health’s (NIH) National Institute of Mental Health (NIMH) found. Dr. Daniel Weinberger and colleagues report on their brain imaging genetics study.
Baby Care :: Swaddling may help babies sleep soundly
The centuries-old practice of swaddling may help young infants sleep more soundly, and could potentially protect against sudden infant death syndrome (SIDS), according to researchers in France and Belgium.
Heart Disease :: Growth factor TGF-beta repairs heart function
Two research teams tricked one of the body?s growth factors into helping the heart repair itself after a heart attack, according to reports in Circulation: Journal of the American Heart Association.
