Exciting research suggests that a shot every one to three months may someday give an alternative to the daily pills that some people take now to cut their risk of getting HIV. The experimental drug has only been tested for prevention in monkeys, but it completely protected them from infection in two studies reported at an AIDS conference on Tuesday. "This is the most exciting innovation in the field of HIV prevention that I've heard recently," said Dr. Robert Grant, an AIDS expert at the Gladstone...

As of today, I have finished many half-marathons and trail half-marathons, climbed mountains and ran a marathon, and I'm currently training for another marathon and various obstacle races. What made this possible? CrossFit. Before you click away, hear me out. I'm not going to try to sell everyone on CrossFit because it doesn't work for everyone. I am going to share why it works for me. In the three years I've been combining running with CrossFit, I have not had one injury. My previous injury...

 Health officials in Iowa and Nebraska on Tuesday identified prepackaged salad mix as the source of a severe stomach bug that sickened hundreds of people in both states, but federal authorities said it's not clear whether cyclospora outbreaks elsewhere in the U.S. are also linked to that produce. Cyclospora is a rare parasite that causes a lengthy gastrointestinal illness, and outbreaks of the illness have been reported in 15 states. The U.S. Centers for Disease Control and Prevention said...

Just a few simple habits can make the difference between a fit person and a couch potato, an everyday worker and the outrageously successful. That's because those simple habits work. And these ultra-fit examples are proof. Fit People Don't Diet Michelle Obama, champion of nutrition and physical activity (and owner of some of the most inspiring arms in America), knows that obsessing over every calorie is no way to live. "The truth is, being a healthy woman isn't about getting on a scale or measuring...

A bus company in China has launched a new “safe driving” campaign by suspending bowls of water over their drivers. To avoid getting wet, drivers must drive gently. In today’s technology-obsessed world, this solution is elegantly primitive. You might imagine that this simple yet ingenious idea was conjured by someone functioning at their very best, that such “aha insights” come when innovators are at their peak. Not so. A recent study by Mareike Wieth and Rose Zacks suggests that innovation...

Like many of you, we heard the sad news about Amy Winehouse's death on Facebook. The news spread quickly. Her friend Russell Brand immediately issued an incredible tribute to her, which was one of the most widely discussed responses to her sudden death. Most people immediately assumed that a drug overdose must have taken Amy's life. We don't know how she died, and on some level, it doesn't really matter. She was young, talented and apparently haunted with struggles none of us will ever understand....

The average weight of a newborn baby is about 7 1/2 pounds, which is why it's shocking -- even in Texas -- that a woman has given birth to a 16-pound baby boy. Two feet tall at birth, JaMichael Brown is the biggest baby ever born in the state of Texas. "A lot of the stuff we bought him is too little," mother Janet Johnson told The Today Show. The nurse who helped deliver JaMichael said there are health implications for an infant this large. The medical term for large infants is "macrosomia,"...

Many people know the term 'bunion' and that it occurs on a foot, but don't know exactly what a bunion is. Most people think a bunion is an abnormal growth of bone at the base of the big toe. This is incorrect (at least in most cases). A bunion is actually a structural problem where the big toe joint becomes subluxed and drifts towards the smaller toes. A displaced bone, called a metatarsal, becomes prominent on the inside of the foot. The bunion simply refers to the enlarged prominent...
