New Haven, Conn.—A team led by Yale University researchers has used nanosensors to measure cancer biomarkers in whole blood for the first time. Their findings, which appear December 13 in the advanced online publication of Nature Nanotechnology, could dramatically simplify the way physicians test for biomarkers of cancer and other diseases.

The work provides insight into potential therapeutic for cancer and eye diseases

LA JOLLA, CA—December 10, 2009—Researchers at The Scripps Research Institute have solved a 10-year-old mystery of how a single protein from an ancient family of enzymes can have two completely distinct roles in the body. In addition to providing guidance for understanding other molecules in the family, the research supplies a theoretical underpinning for the protein’s possible use for combating diseases including cancer and macular degeneration.

Neurologists in the US suggest irregular arm swings while walking could be an early sign of Parkinson’s disease and scientific measurement of such a suspected symptom could help diagnose the disease earlier, giving greater opportunity to slow brain cell damage and disease progression.
