Dieters do calories, not exercise
(Dec 18, 2006)


Twice as many dieters count calories to lose weight rather than exercise, a poll has found. Calorie counting is most popular with women – half opt to count their food intake, compared with a third of men. Yet 59% of the 2,000 people surveyed by GlaxoSmithKline Nutritional Healthcare realised exercise makes the greater contribution to personal health.

Aspirin 'blocks prostate problem'
(Dec 9, 2006)


Aspirin and other similar painkillers may halve the risk of developing an enlarged prostate, research suggests. The condition, known as benign prostatic hyperplasia, can make urination difficult or trigger a need to urinate frequently. Minnesota's Mayo Clinic found Non Steroidal Anti-Inflammatory Drugs (NSAIDS) cut men's risk, but did not recommend all men took the medication.

How to live long and prosper
(Nov 27, 2006)


Want to be the first one on your block to live to 100? You are in with a fighting chance if you're the first-born child of a young mother. Natalia Gavrilova and Leonid Gavrilov of the University of Chicago sifted through data gathered on 991 centenarians born in the US between 1875 and 1899 and used US census and Social Security Administration records to reconstruct the family histories of 198 of them, searching for anything they had in common.

DNA comparisons
Humans show major DNA differences
(Nov 23, 2006)


Scientists have shown that our genetic code varies between individuals far more than was previously thought. A US-led team made a detailed analysis of the DNA found in 270 people and identified vast stretches in their codes to be duplicated or even missing. A great many of these variations are in areas of the genome that would not damage our health, Stephen Scherer and colleagues told the journal Nature. But others are – and can be shown to play a role in a number of disorders.

Alzheimer's heart link explained
(Nov 22, 2006)


Scientists have discovered how heart disease or a stroke may trigger Alzheimer's disease. Both conditions lead to a reduction of oxygen flow to the brain. A University of British Columbia team, studying mice, found this stimulates increased development of the protein clumps thought to cause Alzheimer's.

back pain
Natural chemical 'beats morphine'
(Nov 14, 2006)


The human body produces a natural painkiller several times more potent than morphine, research suggests. When given to rats, the chemical, called opiorphin, was able to curb pain at much lower concentration than the powerful painkiller morphine. The French team said their findings could be lead to new pain treatments.

Cool down – you may live longer
(Nov 3, 2006)


The refrigerator is used to lengthen the life of your food, and a new study suggests a similar principle could prolong your life, too. Researchers have found that lowering the body temperature of mice by just 0.5C extends their lifespan by around 15%. In the future, people might be able to take a drug to achieve a similar effect on body temperature and enjoy a longer life, they say. The only previously proven method of significantly increasing the lifespan of an animal has been through a restricted calorie diet.

Wine 'allows guilt-free gluttony'
(Nov 2, 2006)


A chemical found in red wine could make guilt-free gluttony a reality, an international study suggests. When given to mice, it countered some effects of a high-calorie diet, improving their health and increasing their life-span, the team reported. However, the chemical could not reverse all consequences of overeating – the mice did not lose any weight.
