Man completely paralysed recovers

Graham Miles, 66, said that through sheer willpower he regained the use of his body after he was left completely paralysed except for his eyes by a stroke in the stem of the brain which connects it to the body.

His recovery is such that he can now walk, talk and even races cars.

But while it has amazed doctors and his family and friends, it has also reopened the debate about assisted suicides and the assumption that completely paralysed patients can never recover.

Mr Miles, a father-of-two, believes he overcame the devastating condition by tapping into the “extra capacity” of the brain.

Yoga Shows Potential to Ward Off Certain Diseases


By Rachael Rettner, LiveScience Staff Writer

Practicing yoga may do more than calm the mind — it may help protect against certain diseases, a new study suggests.

In the study, women who had practiced yoga regularly for at least two years were found to have lower levels of inflammation in their bodies than did women who only recently took up the activity.

Inflammation is an immune response and can be beneficial when your body is fighting off infection, but chronically high levels of inflammation are known to play a role in certain conditions, including asthma, cardiovascular disease and depression.

Inflammation is known to be boosted by stressful situations. But when yoga experts were exposed to stress (such as dipping their feet in ice water), they experienced less of an increase in their inflammatory response than yoga novices did.

“The study is the first one, I think, to really suggest how yoga could have some distinctive physical benefits in terms of the immune system,” said researcher Janice Kiecolt-Glaser of Ohio State University. “It suggests that regular yoga practice is really good for you.” she told LiveScience.

Tai Chi Reported to Ease Fibromyalgia


By PAM BELLUCK

The ancient Chinese practice of tai chi may be effective as a therapy for fibromyalgia, according to a study published on Thursday in The New England Journal of Medicine.

A clinical trial at Tufts Medical Center found that after 12 weeks of tai chi, patients with fibromyalgia, a chronic pain condition, did significantly better in measurements of pain, fatigue, physical functioning, sleeplessness and depression than a comparable group given stretching exercises and wellness education. Tai chi patients were also more likely to sustain improvement three months later.

“It’s an impressive finding,” said Dr. Daniel Solomon, chief of clinical research in rheumatology at Brigham and Women’s Hospital in Boston, who was not involved in the research. “This was a well-done study. It was kind of amazing that the effects seem to carry over.”

Meditation Boosts Attention Span

By LiveScience Staff

The life of a Buddhist monk may seem far-removed from the busy, gadget-packed daily buzz most of us experience. But new research suggests daily meditation can give us a piece of the peaceful life, as the focused practice boosts attention spans.

“You wonder if the mental skills, the calmness, the peace that [Buddhist monks] express, if those things are a result of their very intensive training, or if they were just very special people to begin with,” said Katherine MacLean, who worked on the study as a graduate student at the University of California – Davis.

Gel could replace fillings


Dentists could soon hang up their drills. A new peptide, embedded in a soft gel or a thin, flexible film and placed next to a cavity, encourages cells inside teeth to regenerate in about a month, according to a new study in the journal ACS Nano. This technology is the first of its kind.

The new gel or thin film could eliminate the need to fill painful cavities or drill deep into the root canal of an infected tooth.

“It’s not like toothpaste,” which prevent cavities, said Nadia Benkirane-Jessel, a scientist at the Institut National de la Sante et de la Recherche Medicale and a co-author of a recent paper. “Here we are really trying to control cavities (after they develop).”

Life-extending Drug May Also Combat Obesity

By Rachael Rettner, LiveScience Staff Writer

The compound resveratrol, which is present in red wine and gained fame for its supposed life-extending properties, might also help combat obesity, a new study in animals suggests.

The results show lemurs, members of the primate family, gained less weight during their seasonal fattening period when they consumed daily resveratrol supplements.

The drug also boosted the primates’ metabolism and appeared to cause the animals to cut back their food at mealtime, factors that could have contributed to the anti-obesity effects.

Broccoli juice ‘better than sunscreens’


Broccoli juice is better than conventional sunscreens when it comes to protecting against the sun’s harmful ultraviolet rays, research has shown.

Tests on six volunteers exposed to pulses of UV radiation showed the extract reduced sunburn symptoms by up to 78 per cent.

Conventional sunscreens used in the same experiments were essentially ineffective.

The ointment was made from extracts of three-day-old broccoli sprouts rich in protective compounds called sulphoraphanes. Unlike a normal sunscreen, it does not absorb UV light to prevent it entering the skin. Instead, it works inside the body by boosting the production of enzymes that protect cells against UV damage and the risk of skin cancer.

Protection is said to last for several days.

Dogs Can Detect Prostate Cancer

By Benjamin Radford, LiveScience’s Bad Science Columnist

A study presented earlier this month at a meeting of the American Urological Association by a team of French researchers found that a particular dog breed, Belgian Malinois shepherd dogs, can be trained to detect prostate cancer.

Doctors at Paris’s Hospital Tenon trained the dogs to distinguish between the smell of urine from men with prostate cancer and those without it. At the end of the training and study the dogs correctly identified 63 out of 66 samples.

It sounds bizarre, but there might be something to it. Many animals have far keener senses than humans; cats can see in near darkness, elephants’ sensitive feet can detect the footsteps of other elephants miles away, and so on. Dogs are of course known for their remarkable sense of smell, which is why they are used by law enforcement to sniff out drugs, explosives and escaped prisoners.

Meditation Dulls Experience of Pain

By Charles Q. Choi, LiveScience Contributor

People who regularly meditate apparently find pain less unpleasant, because their brains are busy focusing on the present and so anticipate the pain less, blunting its emotional impact, a new study reveals.

Meditation is becoming increasingly popular as a way to treat chronic illness, such as the pain caused by arthritis. To better understand how it works, scientists recruited 12 volunteers with a diverse range of experience with meditation, spanning anywhere from no experience to decades. The kind of meditation practiced varied across individuals, but all included “mindfulness meditation,” which trained them to sustain focus on the present.

Kissing kid’s owies may benefit health

Soothing moms lower stress hormones tied to disease

By JR Minkel, LiveScience Contributor

A loving mother who kisses her child’s boo-boos may be providing more health benefits than she knows.

New research indicates that early childhood experiences can have a lasting effect on health by influencing a person’s risk for chronic inflammation, the immune reaction that is the body’s first line of defense against disease.
