New oxygen gel could prevent amputation in diabetic wound patients

Chronic wounds often spiral out of control because oxygen can’t reach the deepest layers of injured tissue. A new gel developed at UC Riverside delivers a continuous flow of oxygen right where it’s needed most, using a tiny battery-powered system. In high-risk mice, wounds healed in weeks instead of worsening. The innovation could dramatically reduce amputations—and may even open doors for lab-grown organs.

Scientists discover hidden brain cells that may stop Alzheimer’s tau buildup

Scientists have uncovered a surprising new role for little-known brain cells called tanycytes that may influence the development of Alzheimer’s disease. These specialized cells appear to help remove toxic tau protein from the brain by transporting it from the cerebrospinal fluid into the bloodstream. When tanycytes become damaged or dysfunctional, tau can accumulate in the brain, a hallmark of Alzheimer’s.

Air ambulance teams are changing who survives critical injuries

Advanced care provided by air ambulance teams was linked to higher survival rates in major trauma patients. Researchers found that more people survived than predicted by standard models, including many with severe injuries and low chances of survival. Younger patients and those more responsive at first assessment benefited most. Outcomes for traumatic cardiac arrest also improved steadily over the study period.

Scientists discover protein that triggers diabetic blindness

A newly identified protein may hold the key to preventing diabetic blindness. Researchers discovered that LRG1 triggers the earliest damage in diabetic retinopathy by constricting tiny retinal blood vessels and reducing oxygen supply. In mice, shutting down this protein stopped the damage before it could take hold. The finding could pave the way for treatments that protect vision before symptoms ever begin.
