Sensor Chip for Monitoring Tumors

A chip implant may soon be capable of monitoring tumors that are difficult to operate on or growing slowly. Medical engineers at Technische Universitaet Muenchen (TUM) have developed an electronic sensor chip that can determine the oxygen content in a patient's tissue fluid. This data can then be wirelessly transmitted to the patient's doctor to support the choice of therapy. A drop in oxygen content in tissue surrounding a tumor indicates that the tumor might be growing faster and becoming aggressive.

Natural Alzheimer's-Fighting Compound Created Inexpensively in Lab

Scientists at Yale University have developed the first practical method to create a compound called huperzine A in the lab. The compound, which occurs naturally in a species of moss found in China, is an enzyme inhibitor that has been used to treat Alzheimer's disease in China since the late 1990s and is sold in the U.S. as a dietary supplement to help maintain memory. Scientists believe it could also potentially combat the effects of chemical warfare agents.
