Chocolate Walk

In a recent study, British researchers asked a group of chocolate eaters to stay away from the tasty treat for three days.  Instead, they were asked to take either a 15-minute walk or rest.  The group that took a walk reported lower cravings during and up to 10 minutes after their walk.  The walking group was also less likely to feel tempted when asked to un-wrap a chocolate bar.

Re-growing Retinas

Researchers at the University of Washington have re-grown retina cells in mice for the first time ever- and the findings hold promise for similar success in humans.  In the animal studies, a substance was injected into the retina to clear out a cell found near the surface.  Then they added chemicals, including insulin, designed to stimulate re-growth of retinal cells.  The scientists say future studies could lead to new treatments for vision loss from diseases, like macular degeneration. 

Hibiscus Help

In a recent study, a group of volunteers with high blood pressure was asked to drink three cups of hibiscus tea daily for six weeks.  In the end, the group that drank the flavorful tea had over a seven point drop in their systolic blood pressure.  The study was recently presented at the American Heart Association's annual conference.  However, while hibiscus tea may help control blood pressure, scientists say more research needs to be done.
