Scientists at Northwestern University have created a soft, wireless brain implant that delivers patterned light directly to neurons, enabling mice to interpret these signals as meaningful cues without relying on sight, sound or touch. The fully implantable device uses an array of up to 64 micro-LEDs to generate complex activity patterns across the cortex, a development that could advance next-generation prosthetics and sensory therapies, according to Northwestern and Nature Neuroscience.
Researchers have developed a paper-thin brain implant called BISC that creates a high-bandwidth wireless link between the brain and computers. The single-chip device, which can slide into the narrow space between the brain and skull, could open new possibilities for treating conditions such as epilepsy, paralysis, and blindness by supporting advanced AI models that decode movement, perception, and intent.

Researchers have developed tiny ingestible hydrogel microspheres packed with engineered bacteria that glow when they encounter blood in the gut, potentially offering a quick, noninvasive way to monitor intestinal disease. In mouse models of colitis, the sensors detected heme — a component of blood — within minutes and produced stronger signals as disease severity increased.
