Scientists have identified and activated a small group of neurons responsible for the initiation of learned movements. The study used cutting-edge techniques to not only “read” brain activity down to the level of individual cells, but “write” patterns that allowed researchers to control movement.

Every organ and tissue progressively loses function as it ages, but aging tissues retain a latent capacity for rejuvenation. A new study, led by Wyss Institute Core Faculty member George Church, used gene expression data and machine learning to develop a novel “transcriptomic age predictor,” which pinpoints the “transcriptional age” of cells. Using this predictor as a readout in an over-expression screen, the team identified the RNA processing factor SRSF1and demonstrated that it can rejuvenate several “hallmarks of aging,” and significantly increase the healthspan and lifespan of aged mice. 

SAN ANTONIO — October 14, 2026 — Southwest Research Institute (SwRI) has developed a new tool that uses neuromorphic cameras to detect unmanned aerial system (UAS) drones. SwRI’s Hierax system pairs event-based cameras, dynamic sensing technology that mimics the power of human eyesight, with custom software to detect fast-moving drones in complex aerial scenarios.

A new commentary on the evolving role of artificial intelligence in healthcare makes an urgent plea to physicians.

The on-demand availability of artificial intelligence chatbots means that most individuals have quick, easy access to a wealth of information. The ease and accessibility of these tools may make it tempting to turn to AI for advice about mental health. But it’s important to note that these systems are prone to reinforcing a user’s existing beliefs or, in some cases, providing inaccurate information. 

AI chatbots should never be used to diagnose or treat mental health conditions. Instead, AI tools should be used as a supplement to professional care.
