Is it possible that your life expectancy could be estimated according to the amount of wear and tear on your walking shoes? It may seem unlikely, but new research printed in The Journal of the American Medical Association says that this is entirely possible.
The first issue of the Journal released for 2011 revealed details of a nine cohort study that found a correlation between walking gait and longevity in older Americans. Participants allowed study professionals to follow their lives for a period of fourteen years, and during that time some passed away and some remained living. Researchers found that accurate predictions for length of life could be made from gait data collected for each participant.

Oxytocin, the “love hormone” that builds mother-baby bonds and may help us feel more connected toward one another, can also make surly monkeys treat each other a little more kindly.
Administering the hormone nasally through a kid-sized nebulizer, like a gas mask, a Duke University research team has shown that it can make rhesus macaques pay more attention to each other and make choices that give another monkey a squirt of fruit juice, even when they don’t get one themselves.
Two macaques were seated next to each other and trained to select symbols from a screen that represented giving a rewarding squirt of juice to one’s self, giving juice to the neighbor, or not handing out any juice at all.

National Jewish Health researchers and their colleagues in the COPDGene research consortium report that a computerized form of radiology, known as quantitative CT, can offer valuable prognostic information for patients and doctors beyond the standard breathing tests most commonly used to evaluate chronic obstructive pulmonary disease (COPD).
Our findings indicate that quantitative CT scans can help identify patients at greater risk for damaging exacerbations of their disease, said James D. Crapo, MD, Professor of Medicine at National Jewish Health and co-author of the paper that appeared in the October 2011 issue of Radiology.
