Darker fruits could fight cancer
(Aug 20, 2007)

The compounds which give certain fruit and vegetables their dark colour may contain powerful cancer fighting properties, US research suggests. Studies on rats and human cells found anthocyanins – which colour red, purple and blue fruits – notably slowed the growth of colon cancer cells. The more exotic the plant the better: purplecorn and bilberry were found to be much more potent than the radish.

Modern life pushes up cancer rate
(Aug 10, 2007)

Too much food, alcohol and sun has fuelled a massive rise in some forms of cancer, warn UK experts. Cases of melanoma, the most dangerous form of skin cancer, have risen by 40% in the past decade, figures from Cancer Research UK show. And mouth cancer, which is associated with smoking and drinking, has risen by almost a quarter.

Coffee 'protects female memory'
(Aug 7, 2007)

Caffeine may help older women ward off mental decline, research suggests. French researchers compared women aged 65 and older who drank more than three cups of coffee per day with those who drank one cup or less per day. Those who drank more caffeine showed less decline in memory tests over a four year period.

Alzheimer's drugs 'help glaucoma'
(Aug 7, 2007)

Drugs which slow the progress of Alzheimer's disease may protect patients at risk of eye damage from glaucoma, say researchers. The University College London team said experiments suggested there were strong similarities between the conditions. But they stress that the 500,000 UK people with glaucoma are not at higher risk of Alzheimer's.

Gene for left-handedness is found
(Jul 31, 2007)

Scientists have discovered the first gene which appears to increase the odds of being left-handed. The Oxford University-led team believe carrying the gene may also slightly raise the risk of developing psychotic mental illness such as schizophrenia. The gene, LRRTM1, appears to play a key role in controlling which parts of the brain take control of specific functions, such as speech and emotion.

Alcohol link to bowel cancer risk
(Jul 30, 2007)

A daily pint of beer or a large glass of wine raises the risk of bowel cancer by about 10%, research suggests. The Cancer Research UK study found that the more you drink, the more the risk of the disease increases. Those who drank more than 30 grams of alcohol – less than a couple of pints of strong lager – raised their risk by about 25%.

Grapefruit link to breast cancer
(Jul 18, 2007)

Eating grapefruit every day could raise the risk of developing breast cancer by almost a third, US scientists say. A study of 50,000 post-menopausal women found eating just a quarter of a grapefruit daily raised the risk by up to 30%. The fruit is thought to boost levels of oestrogen – the hormone associated with a higher risk of the disease, the British Journal of Cancer reported.

Drinking milk cuts diabetes risk
(Jul 15, 2007)

Drinking a pint of milk a day may protect men against diabetes and heart disease, say UK researchers. Eating dairy products reduces the risk of metabolic syndrome – a cluster of symptoms which increase likelihood of the conditions – the Welsh team found. In the 20-year study, published in the Journal of Epidemiology and Community Health, metabolic syndrome increased the risk of death by 50%.

HRT 'no benefit' to older hearts
(Jul 12, 2007)

More evidence that hormone replacement therapy could be harming, not protecting the hearts of older women has been published. Research into 5,000 women from the UK, Australia and New Zealand suggests women over 60 are more at risk of heart and blood problems. The British Medical Journal study backs major US research which revealed risks for millions of women worldwide.

Moles 'good indicator to ageing'
(Jul 11, 2007)

The number of moles may offer an indication of how quickly the body ages, a study suggests. King's College London scientists compared key ageing DNA with the number of moles in a study of 1,800 twins. They found the more moles a person had, the more likely their DNA was to have the properties to fight off ageing.

Tummy fat 'can grow new breasts'
(Jul 11, 2007)

Fat from the tummy or bottom could be used to grow new breasts in a treatment which could be carried out in an hour – or a lunch break. Scientists say they can create a fat mixture with concentrated stem cells, which, when injected into the breast, apparently encourages tissue to grow. The therapy, detailed in Chemistry and Industry Magazine, could help cancer patients who have had mastectomies.

Organic food 'better' for heart
(Jul 9, 2007)

Organic fruit and vegetables may be better for you than conventionally grown crops, US research suggests. A ten-year study comparing organic tomatoes with standard produce found almost double the level of flavonoids – a type of antioxidant. Flavonoids have been shown to reduce high blood pressure, lowering the risk of heart disease and stroke.

Yawning may keep us 'on the ball'
(Jul 5, 2007)

Yawning may appear the height of rudeness, but in fact your body is desperately trying to keep you awake, according to research from the US. Psychologists who studied 44 students concluded that yawning sent cooler air to the brain, helping it to stay alert.
