Living brain cells wired into a biocomputer could be the future of how robots learn to move and interact with the world around them.
Brain injuries can result in significant damage to the cerebral cortex, and restoring the cellular architecture of the tissue remains challenging. Here, the authors use a droplet printing technique to fabricate a simplified human cerebral cortical column and demonstrate its functionality and potential for future personalized therapy approaches.
In 2024, researchers transformed readings of an epic upheaval of Earth’s magnetic field flipping 41,000 years ago into an eerie, auditory experience.
Now a team containing some of those same scientists has sonified an even earlier flip, from epochs ago.
The resulting cacophony is an unnerving translation of geological data on the Matuyama-Brunhes reversal, a switching of the planet’s magnetic poles that took place roughly 780,000 years ago.
The National Institute of Standards and Technology (NIST) U.S. has set a new world record for the most accurate aluminum ion-based optical atomic clock.
This clock sets a new time-keeping benchmark, accurately measuring a second down to its 19th decimal place. That’s a major leap, making it 41% more accurate and 2.6 times more stable than the former record holder.
The aluminum ion clock’s accuracy record stems from two decades of persistent refinement.
