New silicon ‘Neuropixels’ probes record activity of hundreds of neurons simultaneously

Promise to have a major impact on neuroscience

New magnetism-control method could lead to ultrafast, energy-efficient computer memory

A cobalt layer on top of a gadolinium-iron alloy allows for switching memory with a single laser pulse in just 7 picoseconds. The discovery may lead to a computing processor with high-speed, non-volatile memory right on the chip. (credit:  Jon Gorchon et al./Applied Physics Letters)

Daydreaming means you’re smart and creative

It also enables you to switch to "autopilot" for routine tasks like driving

Researchers watch video images people are seeing, decoded from their fMRI brain scans in near-real-time

Advanced deep-learning "mind-reading" system even interprets image meaning, providing high-level categories (face, bird, etc.)
