Researchers identified that a protein called Sigma-1 receptor (Sig1R) is carried inside tiny particles called extracellular vesicles (EVs), which cells release, and that it is particularly found in vesicles marked by the CD63 protein. This finding suggests Sig1R could serve as a new marker for these vesicles and opens the door to using them as a potential biomarker for brain diseases like Alzheimer’s.

A study from India demonstrated that a “telesimulation” program, where doctors in training competed in trauma scenarios over Zoom, was feasible and could help train many more doctors across large distances with limited resources. This low-cost digital strategy offers a promising solution to address the critical shortage of emergency trauma care providers in low and middle-income countries, helping to save more lives.
