  • Crawling Pill Cam

The innovative pill camera has given doctors a view of the intestines never before seen, but once the pill gets swallowed, doctors have no way to control its movement. Now scientists are working on the next generation of this viewer, giving the pill sized camera legs for maneuvering. In the journal of Microelectronics and Microengineering, scientists from Italy and Korea report on a modified video pill that incorporates six legs. The legs will allow the camera to stop on the intestinal wall to take a closer look at an area that might be a concern. Human trials are expected to begin soon.

  • Light Exercise

If you're not the type to sit still, another study shows light exercise decreases cellular aging in the brain. At the University of Florida, a study in rats finds regular mild exercise can prevent oxidative damage. In people, that translates to a daily 30-minute walk or a light 1-mile run. Oxidative damage has been associated with the loss of brain cells linked to Alzheimer's and Parkinson's disease. Researchers looked at groups of rats that had lived to old age. Some were more sedentary, while others had access to an exercise wheel.

  • Cold Feet

A new study shows that having cold feet, literally, may cause the common cold. During a recent study, 90 participants kept their bare feet in cold water for 20 minutes and then monitored their health for 4 to 5 days. About 10% of the group developed a cold within days. Researchers say dipping feet into cold water may constrict blood vessels in the nose, reducing the ability to fight off infection, but they add there's always the chance the study group with the sniffles may have already been exposed to cold germs but were not showing symptoms at the time of the study.
