Regular doses of ibuprofen extended the lifespan of multiple species, according to research published in the journal Public Library of Science, Genetics.
"We first used baker's yeast, which is an established aging model, and noticed that the yeast treated with ibuprofen lived longer," said Dr. Michael Polymenis, an AgriLife Research biochemist in College Station. "Then we tried the same process with worms and flies and saw the same extended lifespan. Plus, these organisms not only lived longer, but also appeared healthy."
He said the treatment, given at doses comparable to the recommended human dose, added about 15 percent more to the species lives. In humans, that would be equivalent to another dozen or so years of healthy living.

So two of the diets in the study were high in carbs overall, but one was made up of low-glycemic-index foods while the other was composed of high-glycemic-index foods. The other two diets were low in carbs overall, with the same breakdown or low- and high-glycemic items
In fact, among those eating the high-carb diets, those consuming low-glycemic-index foods had worse insulin response and higher LDL cholesterol…
we did not show that the glycemic index of the carb really had any favorable effect," says Sacks.
That suggests that all the attention to knowing the glycemic index of various foods—and basing your eating habits on these numbers—may not be worth the effort.'
Speed. That's key to ending the Ebola epidemic, says the director of the U.S. Centers for Disease Control and Prevention.
Dr. Thomas Frieden is visiting West Africa this week to figure out how to reduce the time it takes to find new Ebola cases and isolate them.
Otherwise, Ebola could become a permanent disease in West Africa.

A metal-detecting blood test that can give vital early warning of breast cancer is being developed by Oxford University scientists.
They hope the inexpensive and simple test will spot the disease long before a woman develops a lump – and say it could be used in a national screening programme.
Picking up the cancer at the earliest stages when it is easiest to treat could save thousands of lives, as well as spare patients and their loves ones the pain and distress of prolonged illness.
Researcher Fiona Larner said: 'Prevention is better than cure.
'There is a survival rate of about 80 per cent for breast cancer but the earlier you can detect it, the more chance you have of treating it.
