Singer Whitney Houston appears to have suffered a heart episode before accidentally drowning in the bathtub of a Beverly Hills hotel suite, according to coroner's officials who listed cocaine use as a contributing factor. The autopsy results were released Thursday after weeks of intense speculation over how the 48-year-old pop star died. The case marks another high-profile Hollywood death connected to drug use, coming less than three years after Michael Jackson died suddenly at his Holmby Hills mansion.

Could freestyle skier Sarah Burke, who died Jan. 19, nine days after a devastating crash, have been helped by an experimental drug? A new study offers a glimmer of hope for future victims of traumatic brain injury. In the hours after she has sustained a blow to the head, the victim of a traumatic injury experiences a slow down of blood flow to the brain--arguably when she needs it most. That mismatch between a brain's response and its needs in the wake of injury has set many a neuroscientist thinking: Can a way be found to keep the flow of oxygenated blood pumping normally?

If you see professional athletes or weekend warriors with a crazy crosshatch of tape on their shoulders, knees or elbows, they probably aren't making a fashion statement. Chances are they're trying to tape over some pain. So-called kinesiology tapes — two prominent examples are Kinesio Tex Tape and KT Tape — gained worldwide attention during the 2008 Olympics, largely thanks to the heavily taped shoulder of American beach volleyball player Kerri Walsh. Unlike traditional tapes that wrap around joints to provide support and compression, kinesiology tape sticks directly to the sore spots like big Band-Aids.

The cells that line blood vessels, called endothelial cells, regulate blood flow to tissues. At least, that's what everyone thought until recently. Now researchers know that endothelial cells do much more and may even be harnessed for their power to stop cancer. In a study published this week, researchers used endothelial cells to slow cancer growth in mice. In the 1980s, researchers realized endothelial cells did much more than serve as gatekeepers of blood flow. The cells influence the behavior of blood vessels, blood clotting, tissue repair and inflammation by releasing certain proteins.

The premise Twenty-seven-year-old Aron Ralston ( James Franco) is a mechanical engineer and thrill-seeker. He is in Utah's Blue John Canyon when he falls down a narrow canyon, and his arm is pinned by a large chalkstone boulder. He watches as his fingers turn blue and gray from insufficient blood flow (ischemia). Though he doesn't appear to be in pain, he is unable to free himself. He has very little food and water, and finally, as he grows dehydrated, he drinks his own urine.

Most savvy exercisers know that a combination of aerobic and resistance training is best, since one works the cardiovascular system and the other targets muscles and bones. A new study looks even deeper into the two workout methods, finding that both have distinct benefits for the heart and vascular system. The small study focused on 10 healthy men, average age about 25, who performed 30-minute bouts of cycling as well as eight resistance training exercises. The participants were monitored to see how their blood vessels responded to the different forms of exercise.
