Deep brain stimulation (DBS) is a therapeutic technique that delivers electrical pulses to specific areas of the brain via an implant to modulate neural activity. It is already widely used for movement disorders such as Parkinson

With artificial intelligence (AI) data centers consuming electricity at a growing rate, identifying a sustainable computing solution to offset these massive community and environmental disruptors is proving critical.

Smart glasses need compact, efficient displays that can produce detailed images without drawing too much power. Laser beam scanning is one approach to meeting these requirements. Rather than using a fixed array of pixels, these displays steer a laser beam across the field of view, building an image point by point.

Software can be updated. Hardware cannot. Manipulation deep within a chip would be almost impossible to detect

Bubbles can be useful tools for microscopic robots, helping them move, steer, create flows of liquid and perform other functions. But designs based on trapping a bubble, a common approach, are unwieldy and unpredictable because bubbles can be hard to catch and control.

Some information, such as exam questions or bid prices, must remain unreadable until an agreed time, even if it has already been delivered. KAIST researchers have used changes in the electric current inside a semiconductor to develop encryption in which information is revealed only after a set amount of time has passed, or can be read correctly only at a specific time. In addition to the key needed to restore the original information, the technology adds a second condition: when the information
