MIT engineers develop a magnetic transistor for more energy-efficient electronics
Transistors, the building blocks of modern electronics, are typically made of silicon. Because it’s a semiconductor, this material can control the flow of electricity in a circuit. But silicon has fundamental physical limits that restrict how compact and energy-efficient a transistor can be.MIT researchers have now replaced silicon with a magnetic semiconductor, creating a magnetic transistor that could enable smaller, faster, and more energy-efficient circuits. The material’s magnetism strongly

Brain–machine interface reveals the origin of a widely used neural signal
Nature, Published online: 15 April 2026; doi:10.1038/d41586-026-01189-1A type of activity in the brain’s cortex, called high gamma, is widely used in studies of brain function, but its origin has long been debated. An experiment using a brain–machine interface now shows that high-gamma activity is generated mainly by synchronized neuronal inputs, rather than outputs, which has implications for the interpretation of neuroscientific studies.

Quantum bottleneck breaks wide open as one light beam carries 23 secure channels at the same time
A new Bar-Ilan University study points to a major advance in quantum information processing, demonstrating a way to send, manipulate, and measure quantum information across many frequency channels simultaneously, rather than one at a time. The study was recently published in the journal Science Advances.
