Researchers have used nanosensors to measure cancer biomarkers in whole blood for the first time. Their findings could dramatically simplify the way physicians test for biomarkers of cancer and other diseases.
Interventional cardiologists created an alternative to open heart surgery by developing a mitral valve clip. To alleviate mitral valve regurgitation--a condition where the heart's mitral valve does not close properly, allowing blood to leak back into the heart--cardiologists insert a catheter.....
Biomedical engineers developed a robotic arm to very precisely resurface the knee before replacing it. In order to do this, a 3-D image of the knee is generated, providing a live-action view of the knee during surgery. A stereo camera system constantly updates information. With a video.
In Kalahari Desert lies the "Devil's claw," a plant that may hold the key to effective treatments. Unfortunately, years of drought have pushed the Devil's claw toward extinction, so scientists are scrambling to devise new ways to produce the medicinal chemicals of the Devil and other rare plants.
