A landmark study into the health dangers posed by mobiles has found people who speak on their handset for more than half an hour a day over 10 years are at greater risk of brain cancer.
The World Health Organisation's Interphone report, to be published this week, will say that "heavy users" are more at risk of developing glioma tumours.
It concludes that there is no increased risk of developing the disease in other users.
However, the minimum amount of time which researchers designated at heavy use was just 30 minutes a day.

A review of research into the affliction found that up to three in ten people claim to have a food allergy of some sort, but blind testing reveals that fewer than ten per cent actually has one.
People were found to be avoiding certain foods because they incorrectly suspected they were allergic to them, while many parents refused to give their children certain foods even though most will overcome their allergies as they grow older.

Researchers in Sweden have carried out the study and found that being chair-bound for too long can raise a person's risk of high blood pressure, sluggish metabolism, weight gain and diabetes. With the average person sitting down for just under nine hours a day at the office, at home or in the car, even a daily workout is unlikely to offset the risks of being seated for too long, the 'Daily Mail' reported.

Scientists claim to have discovered that there's nothing like a nice piece of cheese as it can dramatically boost the immune system.
A new study has revealed that a humble slice of cheese eaten every day is particularly beneficial for the elderly for it acts as a carrier for pro biotic or "friendly" bacteria, the 'Daily Express' reported.

In a major breakthrough which may pave the way for a permanent cure for deafness, scientists claim to have discovered the "Holy Grail" of hearing loss.
An international team, led by Stanford University School of Medicine, has actually found a way of re-creating the sensitive "hair cells", which are vital for hearing, using stem cell technology. And, according to the scientists, the finding could lead to a way for deaf people to regenerate their own inner ear sensory cells to cure the condition.

Experts at the medical technology company, Otto Bock Healthcare, which developed the first mind-controlled arm which is success and the first person to take full advantage of this bionic arm is Christian Kandlbauer. Christian was the "guinea pig" for the four-year research project.
Four years ago Christian lost both his arms after being electrocuted by 20,000 volts. Now he is able to control all of the joints in his left prosthetic arm by merely thinking about what he wants his arm to do.
Experts at the medical technology company, Otto Bock Healthcare, which developed the mind-controlled arm, say it is the first project of its kind in Europe.

There are positive links between access to technology and feelings of well-being, a study claims.
BCS, the Chartered Institute for IT, analysed the results of a survey of 35,000 people around the world.
It found that women in developing countries, and people of both sexes with low incomes or poor education, were most influenced emotionally by their access to technology.

Mothers who smoke during pregnancy are more likely to have children with sleep problems from birth all the way through age 12 years.
Past studies have linked substance abuse during pregnancy to physical and behavioural problems in children. To examine the association between sleep problems and prenatal exposure to cocaine, alcohol, opiates, marijuana and nicotine in children aged 1 month to 12 years, researchers followed 808 American children. Out of all, 374 were exposed to cocaine and/or opiates before birth, while 434 were not.
Children's mothers or other caregivers reported on whether a child had difficulty falling asleep and staying asleep during three periods: one month to four years of age; five to eight years, and nine to 12 years.
It was found that exposure to cocaine, marijuana, or alcohol in the womb had no effect on a child's risk of having sleep problems, but nicotine did, and problems were seen at each of the three time points. Nicotine exposure in the mother's womb was found to be the only unique predictor of sleep problems in the children and the link remained the same even after taking into accounts other factors such as socioeconomic status, marital status, physical abuse, prenatal medical care, and postnatal cigarette smoke exposure.
The above findings show that prenatal exposure to cigarette smoking or nicotine could lead to sleep problems in children.

Children who lived near major highways or railroad intersections have higher diagnoses of asthma, says a new study.
Mayo Clinic researchers used this study to show how neighbourhood environment is a risk factor in understanding the development of paediatric asthma.
"Using nearest propensity score, children who lived in census tracts facing the intersection with major highways or railways had about 40 to 70 percent increased risk of developing childhood asthma," says Young Juhn, Mayo Clinic's Department of Community Paediatric and Adolescent Medicine.

London: Here's some good news for coffee buffs — drinking two cups of the beverage a day — can protect some heart attack victims from complications that may lead to coronary failure, a new study has claimed.
Researchers have carried out the study and found that heart attack patients who drank three or more cups of coffee a day were 90 per cent less likely to develop the condition, known as left ventricular systolic dysfunction or LVSD.
The study's recommendation goes against evidence of people suffering palpitations and irregular heart rhythms after drinking strong coffee, the 'Daily Express' reported.
For their study, the researchers monitored 374 male and female heart attack patients. Those with normal blood pressure were found to be protected against developing LVSD by drinking coffee.

Short sleep ups risk of premature death

London, (IANS) People who sleep for less than six hours each night were 12 percent more likely to die prematurely than those who get the recommended six to eight hours.
The study by the University of Warwick and Federico II University Medical School, Italy, provides evidence of the direct link between short duration of sleep and an increased chance of dying prematurely.
The research also notes that consistent overlong sleeping (over nine hours a night) can be a cause for concern. While, unlike short sleeping, overlong sleeping does not in itself increase the risk of death, it can be a significant marker of underlying serious and potentially fatal illnesses.

Magnets may cure depression in people who have not responded earlier to drugs, a new study has said.
A research team from Medical University of South Carolina, US, has revealed that people who had magnets attached to their heads to activate certain parts of the brain were more likely to report relief from depression than those treated with a similar device without a magnet.
The study involved 190 people, of which just under half were randomly assigned to receive the transcranial magnetic stimulation therapy. These people had to wear a helmet like device that applied a magnetic current to the front section of their brain for around 37 minutes a day for three weeks.

New method to save eyesight loss

London, (ANI): A scientist duo has found a way to boost the nutritional value of corn-a feat that could reduce the number of children in developing countries who lose their eyesight, become ill or die each year because of vitamin A deficiencies.
Corn contains carotenoids, some of which the body can convert to vitamin A.
Beta-carotene is the best vitamin A precursor, but only a very small percentage of corn varieties have naturally high beta-carotene levels.
In Africa and other developing regions, corn is a major staple and hundreds of thousands of children become blind, develop weakened immune systems and die because of diets based largely on corn that lacks sufficient beta-carotene.
Agricultural Research Service (ARS) scientists Marilyn Warburton and Edward Buckler identified genetic sequences linked to higher beta-carotene levels in corn and demonstrating an inexpensive and fast way to identify corn plants that will produce even higher levels.
The study is considered a breakthrough in nutritional plant breeding, reports Nature.
In the study, the researchers surveyed the genetic sequences of corn from around the world through association mapping, a method made possible by recent breakthroughs that accelerate the genetic profiling of crops.

Astronauts may now be able to satisfy their sweet tooth as researchers have found a strawberry that can grow in space with little maintenance and energy.
Cary Mitchell, professor of horticulture, and Gioia Massa, a horticulture research scientist at Purdue University in the US, tested several cultivars of strawberries and found one variety named Seascape, which seems to meet the requirements for becoming a space crop.
"What we're trying to do is grow our plants and minimise all of our inputs," Massa said. "We can grow these strawberries under shorter photoperiods than we thought and still get pretty much the same amount of yield."

Speed limits
Researchers think 30mph could be the human limit. Most use the 100m to calculate how fast we can run. The current record for the 100m is 9.58 seconds, by Usain Bolt in 2009. That gives a speed of 23.3mph. But interestingly, during the 60-80m stretch of the race Bolt averaged a speed of 27.8mph.
However, as Neils Bohr, the distinguished physicist, said: "Prediction is very difficult, especially if it is about the future". Many commentators previously suggested under 10s was unbreakable; now Bolt's coach is aiming for 9.4s. The 100m record now held by a woman would have beaten the fastest male back in the Fifties.

Indian scientists wield sophisticated mathematics to dissect and analyse the traditional meditation chanting sound 'Om'.
Two Indian scientists are wielding sophisticated mathematics to dissect and analyse the traditional meditation chanting sound "Om". The Om team has published six monographs in academic journals. These plumb certain acoustic subtleties of Om, which these researchers say is "the divine sound".
Om has many variations. In a study published in the International Journal of Computer Science and Network Security, the researchers explain: "It may be very fast, several cycles per second. Or it may be slower, several seconds for each cycling of [the] Om mantra. Or it might become extremely slow, with the mmmmmm sound continuing in the mind for much longer periods but still pulsing at that slow rate. It is somewhat like one of these vibrations:
'OMmmOMmmOMmm...
'OMmmmmOMmmmmOMmmmm...
'OMmmmmmmmOMmmmmmmmOMmm'."

Rising rates of obesity among young Americans could undermine the future of the US military, two retired generals have warned.
More than a quarter of young Americans are now too fat to fight, they said.
Writing in the Washington Post, the ex-commanders said the fat crisis ruled out more potential military service recruits than any other medical factor.
They want Congress to introduce laws to give US children better nutrition in schools, with less sugar, salt and fat.

Clapping while singing songs is likely to spur development of important skills in children, a first-ever study on the subject says.
"We found that children in the first, second and third grades who sing these songs demonstrate skills absent in children who don't take part in similar activities," explains Idit Sulkin, a member of Ben-Gurion University (BGU) Music Science Lab in the Department of the Arts.
"We also found that children who spontaneously perform hand-clapping songs in the yard during recess have neater handwriting, write better and make fewer spelling errors," Sulkin adds.
