Possible biomarker for colon cancer in people 50 and under

An abnormality of chromosomes long associated with diseases of aging has, for the first time, been linked to colon cancer in people 50 years old and younger, an age group usually considered young for this disease.

More evidence dopamine plays a role in obesity

A brain-imaging study of genetically obese rats conducted at the U.S. Department of Energy's Brookhaven National Laboratory provides more evidence that dopamine - a brain chemical associated with reward, pleasure, movement, and motivation - plays a role in obesity.

Cognitive performance in long-term abstinent elderly alcoholics

In a new study comparing elderly abstinent alcoholics with light- or nondrinking peers, the recovering alcoholics generally demonstrated equal or superior cognitive functioning to those who were not alcoholic.

The financial burdens of overweight and obesity among elderly Americans

What many Americans eat and how little they exercise could wind up costing them - and American taxpayers - some serious money. Moreover, the overweight and obese may lose months from their lifespans.

Extract of broccoli sprouts protects from ultraviolet radiation

A team of Johns Hopkins scientists reports in this week's issue of the Proceedings of the National Academy of Sciences that humans can be protected against the damaging effects of ultraviolet (UV) radiation - the most abundant cancer-causing agent in our environment - by topical application of an extract of broccoli sprouts.

Longer-living, healthier mouse holds clues to human ageing

A study by scientists at UCL (University College London) shows that mice lacking the insulin receptor substrate (IRS)-1 are more resistant to ageing than normal mice.

Study examines effects of caregiving

A new study from the USC Davis School of Gerontology found that caregivers of different ethnicities showed few negative mental or physical health effects as a result of tending to a family member with dementia.

New model helps explain rules governing the transmission of microbes

Many of the most successful microbes are those that inhabit but do not kill their host. Cheaters lose. Tuberculosis settles into the lungs. Helicobacter pylori, the microbe causing ulcers, burrows into the stomach where it thrives on acids. And Salmonella typhi takes up residence in the gallbladder. All of these organisms can persist in our bodies for decades. What explains their success?

Statins appear to preserve lung function

Statins are known to be good for lowering cholesterol and maybe even fighting dementia, and now they have another reported benefit: they appear to slow decline in lung function in the elderly - even in those who smoke.

New gene findings show that controls of lifespan and cancer have deep, common roots

A person is 100 times more likely to get cancer at age 65 than at age 35. But new research reported in the journal "Nature Genetics" identifies naturally occurring processes that allow many genes to both slow aging and protect against cancer in the much-studied C. elegans roundworm.
