NIBIB-funded researcher Stan Opella, Ph.D, has developed a new technique for determining the structure of G-Protein coupled receptors (GPCRs,) one which does not require the massive physiological modifications demanded from the current technology, X-ray crystallography.

Researchers at Duke University have developed a new ultrasound imaging technique that non-invasively detects tumors and fibrosis in the liver, thus avoiding the pain and complications associated with biopsy. These researchers are also extending the technique to aid in diagnosing other diseases, as well.
The New York Times features NIBIB grantees Bob Langer and Ralph Weissleder as being “on the front lines of turning discoveries made in the lab into a range of drugs and drug deliver systems. Without this kind of technology transfer, the thinking goes, scientific discoveries might well sit on the shelf, stifling innovation.” Read the full article from The New York Times.
NIBIB-funded research has resulted in a new spectrum of voltage-sensitive dyes (VSDs) that improves optical imaging of brain and heart electrical activity. Fluorinated hemicyanine dyes provide spectral compatibility with newly available optical technologies, offering better photostability and improving the signal to noise ratio (S:N) of the optically recorded voltage activity in cells, tissues, and organs.

In a mouse model of multiple sclerosis (MS), NIBIB-funded researchers Stephen Miller and Lonnie Shea at Northwestern University have developed innovative biotechnology to selectively inhibit the part of the immune system responsible for attacking myelin–the insulating material that encases nerve fibers and facilitates electrical communication between brain cells.
