Beyond Movement: Real-Time Cognitive BCIs for Mood and Thought

A Mount Sinai perspective argues that the next frontier for brain-computer interfaces is cognitive BCIs that decode distributed brain networks and use adaptive neuromodulation in closed loops to detect and treat emerging psychiatric states (depression, anxiety, PTSD, OCD) in real time. The approach combines existing hardware—intracranial recording, adaptive deep brain stimulation, and high-resolution neurochemical sensing—and requires merging reading and writing into a single system, plus cross-sector collaboration to translate into clinical therapies. The market potential is large because psychiatric and cognitive conditions affect far more people than paralysis, motivating renewed academic, startup, and regulatory efforts.

MIT’s Greener Lithium Breakthrough Could Cut Costs and Waste in Mining

MIT researchers report a low-temperature, acid-free method to extract lithium from hard rock spodumene by dissolving the silicate matrix with ammonium fluoride, freeing lithium and aluminum for purification. Tested on 17 ore sources with >95% Li recovery, the process is closed-loop and avoids roasting, potentially lowering costs and carbon waste compared with traditional brine evaporation or hard-rock mining. A pilot via spinout Rock Zero is planned, but industrial-scale testing is still needed and could address the looming lithium supply challenge while reducing mining’s environmental footprint.
