1 Exercise Can Slow, Even Reverse, Skin Aging

Researchers at McMaster University in Toronto report that persons over age 40 who engage in three or more hours per week of moderate to vigorous physical activity have skin that is closer in surface composition to that of persons age 30 and younger than it is to that of their sedentary peers, even past the age of 65. Moreover, when a group of sedentary volunteers over age 65 were placed on a regimen of 30 minutes of moderately strenuous jogging or cycling twice a week, at the end of three months' time the surface layers of their skin appeared about the same as that of persons aged 20 to 40 years. One caveat: in all cases the skin was from areas not exposed to sunlight, and while exercise seems to reverse deterioration due to simple aging, it doesn't effect damage from sun exposure.

2 CDC Overstates Drop in Preschool Obesity

The March report by the CDC that the rate of preschooler obesity had plummeted by 43 percent in the past decade turns out to be overly positive, according to a new analysis by Wake Forest and University of North Carolina researchers. The CDC report cited a drop in preschooler obesity rates from 14 percent in 2003-2004 to 8 percent in 2011-2012, a fairly striking falloff, but using the same data and going back to 1999 showed preschool obesity rates then of 10 to 11 percent, making the reduction to 8 percent statistically less meaningful. More worrisome, from 1999 to 2012 the rate of extreme obesity among children and teens overall rose from 3.8 percent to 5.9 percent, while the rate of severe obesity (equal to an adult BMI of 40) more than doubled, from 0.9 percent to 2.1 percent.

3 Deadly MERS Virus Shows Up in U.S.

The first U.S. case of MERS (Middle East Respiratory Syndrome,) the deadly virus that surfaced two years ago in the Middle East and causes acute respiratory illness and sometimes death, has been reported in Indiana. The patient had just returned from Saudi Arabia when he became ill with fever and breathing problems. He is currently in isolation and is in stable condition, reported the Centers for Disease Control. "This is a rapidly evolving situation," said Assistant Surgeon General Anne Schuchat, who is also the director of the National Center for Immunization and Respiratory Diseases. "The introduction of MERS-CoV is another reminder that diseases are just a plane ride away." MERS has been reported in 401 people in 12 countries, 93 of whom have died.
