Scientists Discover Genes Behind Restless Legs

Two independent groups of scientists have discovered genes linked to Restless Leg Syndrome (RLS), a disorder that affects millions of people worldwide and causes disturbed sleep. One group also found a link between iron deficiency and a gene associated with RLS.

Having trouble committing mass murder? Now there's a cure!

MIT biochemists have identified a molecular mechanism behind fear, and successfully cured it in mice, according to an article in the journal Nature Neuroscience.

Researchers from MIT's Picower Institute for Learning and Memory hope that their work could lead to the first drug to treat the millions of adults who suffer each year from persistent, debilitating fears - including hundreds of soldiers returning from conflict in Iraq and Afghanistan.

Children and young people show elevated leukaemia rates near nuclear facilities

Review covers 136 countries in US, Canada, UK, France, Germany, Japan and Spain.

Leukaemia rates in children and young people are elevated near nuclear facilities, but no clear explanation exists to explain the rise, according to a research review published in the July issue of European Journal of Cancer Care.

Researchers at the Medical University of South Carolina carried out a sophisticated meta-analysis of 17 research papers covering 136 nuclear sites in the UK, Canada, France, the USA, Germany, Japan and Spain.

They found that death rates for children up to the age of nine were elevated by between five and 24 per cent, depending on their proximity to nuclear facilities, and by two to 18 per cent in children and young people up to the age of 25.

Incidence rates were increased by 14 to 21 per cent in zero to nine year olds and seven to ten percent in zero to 25 year-olds.

Exercise, exercise, rest, repeat -- how a break can help your workout

Taking a break in the middle of your workout may metabolize more fat than exercising without stopping, according to a recent study in Japan. Researchers conducted the first known study to compare these two exercise methods-exercising continually in one long bout versus breaking up the same workout with a rest period. The findings could change the way we approach exercise. Who wouldn't want to take a breather for that"

"Many people believe prolonged exercise will be optimal in order to reduce body fat, but our study has shown that repetitions of shorter exercise may cause enhancements of fat mobilization and utilization during and after the exercise. These findings will be informative about the design of [future] exercise regimens," said lead researcher Kazushige Goto, Ph.D. "Most people are reluctant to perform a single bout of prolonged exercise. The repeated exercise with shorter bouts of exercise will be a great help [in keeping up with fitness]."

Links between food cravings, types of cravings, and weight management

Accepting food cravings and keeping them in check may be an important component of weight management, according to findings from the first six-month phase of a calorie-restriction study conducted at the Jean Mayer USDA Human Nutrition Research Center on Aging (USDA HNRCA) at Tufts University. Supplemental results from the Comprehensive Assessment of the Long-term Effects of Restricting Intake of Energy (CALERIE) trial provide new insights into food cravings, specific types of foods craved, and their role in weight control.

"Cravings are really normal; almost everyone has them," says corresponding author Susan Roberts, PhD, director of the USDA HNRCA's Energy Metabolism Laboratory. At the start of the study, 91 percent of the participants reported having food cravings, which are defined as an intense desire to eat a specific food. "Most people feel guilty about having food cravings," says Roberts, "but the results of this study indicate that they are so normal that nobody needs to feel they are unusual in this respect."

In addition, the results indicate that cravings don't go away during dieting. "In fact, 94 percent of the study participants reported cravings after six months of dieting. However,"Roberts says, "participants who lost a greater percentage of body weight gave in to their cravings less frequently. Allowing yourself to have the foods you crave, but doing so less frequently may be one of the most important keys to successful weight control," she adds.

'Indian register' for pregnancies and abortions

An Indian minister has proposed that all pregnant women register with the government and seek its permission if they wish to undergo an abortion.
Women and child development minister Renuka Chowdhury says the move is aimed at stopping the aborting of unwanted female foetuses.

Although prenatal sex determination and selective abortion are banned, far more boys than girls are born.

Critics warn that the new move could backfire and be misused.

Grapefruit link to breast cancer

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.

But the researchers and other experts said more research was still needed.

How sickness makes us sleep. Immune protein makes the body clock turn down a notch.

Getting sick often means getting tired too. Now researchers have tracked down how the chemical responsible for such drowsiness works.

The culprit is a small protein called tumour necrosis factor alpha (TNF-alpha), named for its anti-tumour properties. This compound was known to trigger inflammation in response to infection and some chronic diseases such as rheumatoid arthritis and multiple sclerosis. And it was known to be linked - somehow - to fatigue. Cancer patients treated with TNF-alpha sometimes report severe lethargy, for example. And patients with a sleep disorder called sleep apnea sometimes report less daytime sleepiness after receiving a drug that interferes with TNF-alpha.

But precisely how the protein was affecting sleep habits was unclear.
