Space Technology Yields New Cataract Detection Technique
A compact fiber-optic probe developed for the space program has now been used to create the first non-invasive device for early detection of cataracts, the leading cause of vision loss worldwide.
Sodium/Potassium Ratio Linked to Cardiovascular Disease Risk
Two nutrients, sodium and potassium, likely work together to affect blood pressure and heart disease risk, according to a new study.
Time of Day Can Be Critical in Chemotherapy

New Tool to Predict Colorectal Cancer Risk
A new tool for calculating colorectal cancer risk for people age 50 or older recently came online. It will help health care providers and their patients make informed choices about when and how to screen for colorectal cancer. It might also be used in designing future colorectal cancer screening and prevention trials.
Deep Brain Stimulation Curbs Parkinson Symptoms
Scientists reported that a therapy for treating Parkinson’s disease called deep brain stimulation improved quality of life and gave patients more daily hours without troubling movement symptoms than standard medical care. However, brain stimulation also carried a greater risk of serious adverse events.
Eye Cells Are Out of Sight
A new study sheds light on how a particular kind of cell in the eye—crucial for light-related functions other than seeing—detects light and communicates with the brain. A better understanding of these cells may eventually help in the development of treatments for sleep problems or seasonal depression.
