NIH BRAIN Initiative supporting development of a probe to monitor brain chemistry

May 23, 2022

The human brain remains mysterious, and any progress towards solving that mystery may bring enormous benefits. For one thing, millions of people are afflicted with brain disorders that today are poorly understood and often difficult to treat.

How much light could be shed if we had a technology for making chemical “movies” of brain activity, showing “frame” by “frame” how brain chemistry changes over time—for example, during an epileptic seizure, or in response to delivery of a drug?

New approach enhances muscle recovery in aged mice

April 11, 2022

Scientists have developed a promising new method to combat the age-related losses in muscle mass that often accompany immobility after injury or illness. Their technique, demonstrated in mice, arrests the process by which muscles begin to deteriorate at the onset of exercise after a period of inactivity.

They report their findings in the Journal of Physiology.

Analytical technique helps spot subtle differences in subcellular chemistry

October 5, 2021

Researchers at the University of Illinois Urbana-Champaign can now rapidly isolate and chemically characterize individual organelles within cells. The new technique tests the limits of analytical chemistry and rapidly reveals the chemical composition of organelles that control biological growth, development and disease.
