In the eighties, scientists issued a strange warning: don’t drink grapefruit juice if you’re taking the high-blood-pressure drug felodipine. The study, led by University of Western Ontario’s David Bailey, found that the body’s levels of felodipine mushroomed after people drank the bittersweet nectar. They later identified 50 more medications that exhibited the “grapefruit juice effect,” stamped warning labels on them, and called it a day.
Think smoking is bad for you? Try just breathing. Louisiana scientists have discovered a group of previously undetected air pollutants that when inhaled exposes the average person to 300 times more free radicals than that of one cigarette in a day.
Scientists have succeed in replicating flu pandemic antibodies from 90 year old survivors

Ninety years ago the Spanish flu swept across the globe, killing between 50 and 100 million people in only a few months. Since then, the specter of another flu pandemic dealing death and woe around the world has periodically terrified the medical and popular communities. But scientists searching for ways to prevent a similar outbreak in the form of the H5N1 bird flu have found a cure for the deadliest flu in the most unlikely place: nonagenarian immune systems.

A recent study by Stanford researchers has confirmed your worst fears—that dorky neighbor in the short-shorts who zips by every morning at 6 o'clock in the morning will likely outlive you, and will be healthier in the long run.
A drug tested in virtual war may help soldiers recover from traumatic stress-- and could conquer everyday anxiety

Plenty of medications help people deal with fear, but the most effective one may be a humble antibiotic. Scientists testing a new treatment for veterans with post-traumatic stress disorder (PTSD) say the key to faster recovery might be a 50-year-old tuberculosis drug called
D-cycloserine, or DCS.

Sputnik, satellite virus, in green
Have you lied in bed, aching from fever and coughing, wishing that awful flu virus could get a taste of its own medicine? Well, according to a new study, it turns out that some of those bugs get as sick as we do, and additionally those infections may contribute to the rapid evolution of viruses.
A new breakthrough in stem cell production provides an important tool to researchers studying Lou Gehrig’s disease
By Stuart FoxPosted 08.05.2008 at 3:27 pm 1 Comment
Talk of the promise of stem cells usually revolves around creating new, healthy cells to repair damaged or diseased organs. However, a joint project between Harvard and Columbia Universities has been doing the exact opposite: creating stem cells that will develop into diseased cells. By creating stem cells from people with a known degenerative disorder, the researchers hope to explore the process that cause the diseases, discover where a cure might be most effective, and probe the unexplored area between genetics and disease.

Will the Wii Fit one day add heart rate to the health metrics it monitors? It's possible; but Nintendo might have to purchase the intellectual property. A patent application filed in early 2007 discusses using a Wii-like controller to monitor body temperature, heart rate, or even blood pressure. The patent was filed by Kent Hsu of Taiwan. Check out the first claim below. How's that for a run-on sentence?
How new medical tech gets injured stars off the disabled list and onto the field
By Will CarrollPosted 07.31.2008 at 12:26 pm 1 Comment
If you're a sports fan, you can probably list the top pitchers, the top quarterbacks . . . and the top orthopedic surgeons. A franchise's success—and an athlete's next contract—hinges on how quickly injured superstars return to the field. Here's how doctors are turning what would have been career-ending injuries a decade ago into speed bumps on the way to Canton or Cooperstown
A new pair of high-tech pants monitors the wearer's joints
By Sam BarrettPosted 07.30.2008 at 5:55 pm 0 Comments
A team of engineers at Virginia Tech University has designed a pair of pants that may identify people who have a high risk of falling.
Several small circuit boards containing microcontrollers, sensors, and communication devices -- called e-TAGS -- are embedded in the pants at the hip, knee, and ankle joints. Each foot has a piezoelectric sensor—a sensor that generates an electric pulse through applied stress—at the heel that is connected to an e-TAG in the pants. The whole setup is powered by a nine-volt battery attached near the waist.
