Study Links Potassium to Fewer Strokes in Older Women
Study Links Potassium to Fewer Strokes in Older Women THURSDAY, Sept. 4, 2014 (HealthDay News) -- Could eating foods rich in potassium, such as bananas and potatoes, help lower the risk of stroke and an earlier death for older women?

However, the study's findings were significan...
Sit Less, Protect Your DNA and Live Longer?
Sit Less, Protect Your DNA and Live Longer? WEDNESDAY, Sept. 3, 2014 (HealthDay News) -- Spending less time sitting might increase your lifespan by keeping your DNA young, Swedish researchers say. More time spent on your feet appears to lengthen bits of DNA called telomeres. Telomeres, which protect the end of chromosomes (like the tips that keep shoelaces from fraying), tend to get shorter and shorter until they can't shorten any more, causing cells to die. "Our data indicate that lengthening of our te...
Skin Cells Used to Create Heart Valve for Growing Kids
Skin Cells Used to Create Heart Valve for Growing Kids WEDNESDAY, Sept. 3, 2014 (HealthDay News) -- While artificial heart valves have long been available to adults, making permanent valves for children has been challenging because kids' bodies keep growing. But researchers say they've found a way around that, using a child's skin cells to make a new pulmonary valve for the youngster's heart to replace a faulty one. Using a child's own skin cells to create the new valve reduces the risk of rejection, th...

Study Counters Critics of Plainer Cigarette Packaging
Study Counters Critics of Plainer Cigarette Packaging FRIDAY, Aug. 29, 2014 (HealthDay News) -- Selling cigarettes in plain packages doesn't increase the use of low-cost or illegal tobacco and doesn't harm sales in small stores, according to new research from Australia. Those problems were predicted by the tobacco industry when it tried to prevent Australia from becoming the first country in the world to introduce plain packaging for tobacco products in 2012. Similar legislation is being considered in I...
Spaceflight Might Weaken Astronauts' Immune Systems
Spaceflight Might Weaken Astronauts' Immune Systems FRIDAY, Aug. 29, 2014 (HealthDay News) -- Astronauts may be at heightened risk of illness because space travel appears to disrupt human immune systems, a new study suggests.
