Washington, Nov 5 : Daily doses of multivitamin supplements, including folic acid and vitamin B6 and B12, have no effect in preventing cancer in women, according to a group of researchers.

Folate, vitamin B6, and vitamin B12 (water-soluble, essential B vitamins) are thought to play an important role in cancer prevention.

The study found that folic acid and vitamin B6 and B12 had no significant effect on the overall risk of cancer, including breast cancer, among women at high risk of cardiovascular disease.

London, Nov 5 : Scientists have developed a new drug that mimics the effects of an ingredient in red wine, which may be a powerful weapon in the fight against obesity and diabetes.

They also found that the drug appears to increase energy levels when exercising.

London, Nov 4: Running around like a child in a park could be more beneficial to your health than traditionally adult activities like jogging, University of Glamorgan research has found.

The research team has found that short sharp sprints of up to 30 seconds could be as beneficial as doing up to five sessions of an hour''s exercise a week.

The researchers found that shorter bursts of exercise could be more practical to follow.

To reach the conclusion, the university studied the exercise patterns over several years, comparing short high-intensity sprints to longer endurance training, such as cycling and jogging.

London, Nov 4 : Cancer rates could double in the next 40 years unless actions are taken to stop the rising tide of obesity, health experts have warned.

Studies have shown that the chance of developing major killers like breast and kidney cancer rises as people become increasingly overweight.

Health experts foresee that if trends continue up to one third of British women and half of men could be obese by 2050, up from around a quarter at the moment.

Professor Martin Wiseman, the medical and scientific adviser to the World Cancer Research Fund (WCRF) charity, says that today''s children will face increasing rates of cancer as they grow up unless tough action is taken.

Washington, Nov 4: People who smoke are at an increased risk of losing their ability to smell even the most common odours, say researchers.

The research team also found that second hand smokers were at an increased to developing laryngitis, leading to hoarseness, cough, and chronic clearing of the throat.

The first study led by Norwegian researchers involving 2,294 patients showed that smokers were 12 to 27 percent more likely than non-smokers to experience the symptoms of obstructive sleep apnea, snoring, or nose-related issues.
