Research to boost astronaut fitness on NASA’s mission to Mars

December 15, 2022

Exercise looks a little different en route to the Red Planet, so Professor Marni Boppart (RBTE) got creative. Boppart and her colleagues received $1 million from the Translational Research Institute for Space Health, a NASA-funded institute, to explore the regenerative power of cells in space. Their research will help protect human health aboard Orion, the spacecraft destined to ferry astronauts from the Earth to the moon and Mars.

Understanding the differences between healthy and type 2 diabetes-affected pancreatic islets

November 21, 2022

Pancreatic islets are mini-organs that make and release insulin and several other peptide hormones to control our glucose levels. Although various studies have previously looked at how pancreatic cells communicate with each other, the exact nature of these chemical signals has remained unknown. In a new study, researchers have measured a new set of molecules to determine how these cell-to-cell change in healthy and type 2 diabetes-affected islets to identify therapeutic targets.

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.
