Retirement-age fitness predicted by high school sports participation

Health behavior researchers have found that fit and healthy young men who participated in high school and college sports were also more likely to be physically active when they reached their 70s.The study analyzed survey responses from 712 veterans who had fought in World War II and gotten through it in good health without wounding.

Gene found that 'protects against neurodegenerative diseases'

Scientists from the University of Queensland in Australia say they have discovered that a gene called mec-17 has the ability to protect against adult-onset progressive nerve degeneration. This is according to a study published in the journal Cell Reports.The research team, led by Dr.

Stop smoking ads show damage to brain

Meat, smoking have strongest links to cancer incidence rates

Using 2008 global cancer rates from the World Health Organization, a new international study has found that certain lifestyle factors - specifically smoking and eating diets high in animal products - have the strongest association with cancer rates.Publishing their findings in the journal Nutrients, the researchers say the results could impact international food policies.

Slow eating may reduce hunger but not calorie intake

It is a well known fact that the more calories one consumes, the more weight is gained. Previous studies suggest that eating speed may affect how many calories the body consumes. But new research suggests that eating speed, rather than caloric intake, may have more of an impact on hunger suppression.

Molecular researchers find new key to inflammatory diseases

Biologists have discovered genetic material that may help to explain part of how our immune defense is triggered. Dubbing it THRIL, they say it could be targeted in the development of treatments against inflammatory diseases such as Kawasaki disease, rheumatoid arthritis and inflammatory bowel disease.

Surgery 'better than chemotherapy' for tongue cancer

For the treatment of cancer, many would consider chemotherapy to be the best option. But for tongue cancer, new research suggests that surgery may be the most effective primary port of call. This is according to a study published in the journal JAMA Otolaryngology Head and Neck Surgery.

Fine-tuned MRI may help MS diagnosis

Researchers have found a way to fine-tune MRI scanning that may help to diagnose multiple sclerosis earlier and to track its progression.The research, published in the Proceedings of the National Academy of Sciences (PNAS), has found a way to improve a magnetic resonance imaging (MRI) approach called quantitative susceptibility mapping (QSM).

Low oxygen levels in tumors 'trigger spread of breast cancer'

Researchers have discovered that low oxygen conditions can trigger the production of proteins that contribute to the spread of breast cancer cells. This is according to a study published in the Proceedings of the National Academy of Sciences.Biologists from Johns Hopkins University found that low oxygen conditions prompted increased production of proteins called RhoA and ROCK1.

Some bacteria 'live for long periods' on toys, books and cribs

Researchers from the University at Buffalo in New York say two bacteria that cause many common infections in children and the elderly, such as strep throat and ear infections, can live outside the human body for long periods of time on various objects, including books, cribs and toys.

Reading a novel triggers lasting changes in the brain

Lovers of literature can rejoice: a new study combines the humanities and neuroscience to take a look at what effects reading a novel can have on the brain. Researchers say exploring a book can not only change your perspective, but also it can change your mind - at least for a few days.

'Work with anxiety' rather than seek calm to improve performance

Performance anxiety is better helped by telling yourself to get excited rather than to calm down, says a psychologist publishing the results of experiments looking into fear-inducing prospects, such as public speaking and math tests.Simply saying the phrase, "I am excited" out loud was found to improve performance in the studies by Alison Wood Brooks, PhD, of Harvard Business School.

Beatboxing less harmful to vocal cords than singing

Many of us will have been intrigued by the sound of beatboxing at some point - a highly skilled vocal percussion in which the performer imitates a drum sound with their voice. You may think that compared with standard singing, beatboxing is harsher on the voice. But new research suggests this is not the case.
