Novel detection method unmasks circulating breast cancer cells

Circulating metastatic breast cancer cells can lose their epithelial receptors, a process that enables them to travel through the bloodstream undetected, according to research from The University of Texas M. D. Anderson Cancer Center. more  

Scripps Research scientists crack mystery of protein's dual function

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. more

Moderate weight loss in obese people improves heart function

Obese patients who lost a moderate amount of weight by eating less and exercising more improved their cardiovascular health, says a study at Washington University School of Medicine in St. Louis. more  

New genes for lung disease discovered

Scientists have discovered five genetic variants that are associated with the health of the human lung. The research by an international consortium of 96 scientists from 63 centres in Europe and Australia sheds new light on the molecular basis of lung diseases. more

Scientists use nanosensors for first time to measure cancer biomarkers in blood  

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. more

New biosensors reveal workings of anti-psychotic drugs in the living brain  

Scientists have resolved a question about how a popular class of drugs used to treat schizophrenia works using biosensors that reveal previously hidden components of chemical communication in the brain. more

New inherited eye disease discovered

University of Iowa researchers have found the existence of a new, rare inherited retinal disease. Now the search is on to find the genetic cause, which investigators hope will increase understanding of more common retinal diseases. more
