Vitamin D supplements may help stave off diabetes as they improve insulin effectiveness

Vitamin D appears to bolster insulin in the body - potentially staving off diabetes, new research suggests.

The hormone made by the pancreas is essential for metabolizing glucose, but in a growing number of people (diabetics) its effects are futile - and without it, suffering ensues.

Scientists worldwide are scrambling to curb rates of the condition that can be costly and life-threatening, complicating surgeries, pregnancy, childbirth, and more.

Now, Canadian scientists have presented surprising new data that suggests high doses of the 'sunshine vitamin' could slow the condition in newly diagnosed patients - and may even protect people from developing it.

It significantly improved the action of insulin in the muscle tissue of participants after six months, according to Daily Mail.

How Weight Training Changes the Brain

Most of us discover in middle age, to our chagrin, that brains change with age and thinking skills dip. Familiar names, words and the current location of our house keys begin to elude us.

But a wealth of helpful past research indicates that regular aerobic exercise, such as walking or jogging, can prop up memory and cognition. In the studies, which have involved people and animals, aerobic exercise generally increases the number of new neurons created in the brain’s memory center and also reduces inflammation. Unchecked, inflammation in the brain may contribute to the development of dementia and other neurodegenerative conditions.

Using antibiotics without a prescription is a prevalent public health problem

People using antibiotics without a prescription seems to be a prevalent public health problem. Antibiotics were obtained through various means, including saving leftover prescriptions for later use, getting them from friends and family, or obtaining them from local markets "under the counter."

When people take antibiotics without a prescription, they often take unnecessary medication or choose an inappropriate drug or dose. This practice is associated with avoidable adverse events and may also increase the risk for inducing antibiotic resistance. It is important to understand how prevalent nonprescription antibiotic use is and the factors that contribute to the issue, according to Science Daily.

Resistant malaria spreading in South East Asia

Malaria parasites resistant to key drugs have spread rapidly in South East Asia, researchers from the UK and Thailand say.

The parasites have moved from Cambodia to Laos, Thailand and Vietnam, where half of patients are not being cured by first-choice drugs.

Researchers say the findings raise the "terrifying prospect" drug-resistance could spread to Africa, according to BBC.

However, experts said the implications may not be as severe as first thought.

Harvesting energy from the human knee

Imagine powering your devices by walking. With technology recently developed by a group of researchers at the Chinese University of Hong Kong, that possibility might not be far out of reach.

The group describes the technology in Applied Physics Letters. An energy harvester is attached to the wearer's knee and can generate 1.6 microwatts of power while the wearer walks without any increase in effort. The energy is enough to power small electronics like health monitoring equipment and GPS devices.

"Self-powered GPS devices will attract the attention of climbers and mountaineers," said author Wei-Hsin Liao, professor in the department of mechanical and automation engineering, according to Science Daily.
