  • Blood Test for Tuberculosis

Results of a new study suggest a high-tech blood test may be the best way to screen for Tuberculosis compared to the standard skin test. When comparing the two tests, researchers found the rapid blood test more accurately identified infection with fewer false positives. False positives from the skin test are often seen in patients who've had a Tuberculosis vaccine called BCG.

The new test, called Elispot, works by detecting t-cells in the blood. It's the t-cells that are produced in response to a Tuberculosis infection. This study is published in the Lancet Medical Journal.

  • New Spider Vein Treatment

New technology is changing conventional spider vein treatment. The Transillumination Imaging device adds to a traditional treatment known as Sclerotherapy or Injection Therapy. Transillumination works by passing light through the body to find the deeper source of varicose or spider veins.

Doctors at the Vein Treatment Center in New York City are using this to find the deeper veins. Then injecting a mild chemical solution that causes the vein wall to collapse so that blood can be re-routed to healthy vessels.

  • False Memories?

Ever wondered how someone could believe something even though they, and everyone else, know it's not true. Psychological research from the University of California at Irvine shows that a skillful talker who is very convincing can plant memories in people even unlikely ones that you'd think would be rejected. The research calls into question the reliability of using witnesses who may be convinced they saw something when in fact they didn't.
