...small study involved heart patients undergoing bypass surgery. In half the patients, stem cells harvested from bone marrow in their hipbones were injected into their damaged heart tissue. The results were encouraging, but researchers don't know whether the stem cells transformed into new heart muscle, increased blood-vessel formation or somehow coaxed existing heart cells to become more active. Researchers are finding new sources of adult stem cells, including fat cells, skin, the brain and periodontal ligaments, the fibrous tendons that hold teeth in their sockets...
...there are a lot of things that can throw off the calibration of the whole fragile system, starting with the vessel walls. When we're young, our vessels are healthy and springy, easily stretching and contracting to accommodate blood pressure as it rises and falls. The arteries, which are a type of muscle, even pulse to help keep blood moving along. But the fibers that make up the scaffolding of the vessel walls can take only so much flexing. As we age, the rubbery tissue slowly gets replaced with stiffer collagen. The vessels don't expand as well anymore...

One morning, Teh was finally bundled onto a boat and dropped off at gunpoint on a passing fishing vessel that returned him to Malaysia. (Teh and his family insist that no ransom was paid...
...Cooking System, which cuts the risk of forest fires by allowing campers to prepare soup, pasta, rice and beans--any single-pot dish--quickly and safely. How? The flame is contained within the Jetboil's patented Flux Ring, which channels the heat from a butane burner directly into the vessel. (Fuel canisters sold separately.) Bonus: a neoprene cover insulates the food while protecting campers' fingers from the heat...
