The risk of people developing Type 2 diabetes is lower for people who consume more whole grains, fruits, vegetables, nuts, and legumes, notes a study in PLOS Medicine.

A new study reports the first detection of chiral molecules in space, paving the way to understanding why chirality is "biased" on Earth. Our planet is home to a puzzle involving chiral molecules, those that, despite being mirror images of each other, don't exactly match; imagine a left-handed and right-handled glove, for example. They aren't interchangeable. Life on Earth is made of groups of such molecules that overwhelmingly share just one type of handedness, a phenomenon known as homochirality. The amino acids that make up the proteins in our bodies, for example, are all left-handed.

Six mating positions (amplexus modes) are known among the almost 7,000 species of frogs and toads found worldwide. However, the Bombay night frog (Nyctibatrachus humayuni), which is endemic to the Western Ghats Biodiversity hotspot of India, mates differently. In a new study, scientists have described a new (seventh) mode of amplexus -- now named as dorsal straddle.

(Boston) -- To date, there are no methods that can quickly and accurately detect pathogens in blood to allow the diagnosis of systemic bloodstream infections that can lead to life-threatening sepsis. The standard of care for detecting such blood-borne infections is blood culture, but this takes days to complete, only identifies pathogens in less than 30% of patients with fulminant infections, and it is not able to detect toxic fragments of dead pathogens that also drive the exaggerated inflammatory reactions leading to sepsis.

A virus that infects major freshwater bacteria appears to use stolen bits of immune system DNA to highjack their hosts' immune response.

Microbiologists have discovered that the virus, Cyanophage N1, carries a DNA sequence--a CRISPR--that is generally used by bacteria to fight off viral infection.

"This is the first evidence we've seen that a virus can donate an immunity system via CRISPR," says University of British Columbia virologist Curtis Suttle. "This is like a hacker compromising a computer system, and then immediately patching it to ensure other hackers can't break in."

Sophia Antipolis - June 14, 2016: Fifteen minutes of daily exercise is associated with a 22% lower risk of death and may be a reasonable target for older adults, reveals research presented today at the EuroPRevent 2016 meeting by Dr David Hupin, a physician in the Department of Clinical and Exercise Physiology, University Hospital of Saint-Etienne in Saint-Etienne, France.1

"Age is not an excuse to do no exercise," said Dr Hupin. "It is well established that regular physical activity has a better overall effect on health than any medical treatment. But less than half of older adults achieve the recommended minimum of 150 minutes moderate intensity or 75 minutes vigorous intensity exercise each week."

In a study appearing in the June 14 issue of JAMA, Angela Sauaia, M.D., Ph.D., of the University of Colorado Anschutz Medical Campus, Aurora, and colleagues examined patterns of gunshot wound-associated severity and mortality at a Colorado urban trauma center.

Long-acting opioids are associated with a significantly increased risk of death when compared with alternative medications for moderate-to-severe chronic pain, according to a Vanderbilt study released today in JAMA.

Not only did long-acting opioids increase the risk of unintentional overdose deaths, but they were also shown to increase mortality from cardiorespiratory events and other causes.

Lead author Wayne Ray, Ph.D., and colleagues with the Vanderbilt Department of Health Policy studied Tennessee Medicaid patients between 1999-2012 with chronic pain, primarily back and other musculoskeletal pain, who did not have cancer or other serious illnesses.

British taxpayers spend billions for the health care of an increasingly overweight population. The World Health Organisation predicts that almost three-quarters of men and two-thirds of women in the UK will be overweight or obese by 2030.

Graham MacGregor is Professor of Cardiovascular Medicine at the Wolfson Institute of Preventive Medicine, Queen Mary, University of London was trained as a nephrologist but then became interested in blood pressure control mechanisms, particularly related to the renin-angiotensin system, the mechanisms whereby salt puts up blood pressure. Now he says he knows a magic bullet for halting obesity: unsurprisingly it is in line with all of the latest fad claims in media.

A core platform of the massive promotion of e-cigarettes has been the argument that because these products involve no combustion but only vaporization, they must be substantially less dangerous than smoked tobacco. Few – including me – would disagree with that.
