It developed a laser printing process that can print micrometer-sized parts in the blink of an eye. The international team published the work in Nature Photonics. (DOI: 10.1038/s41566-022-01081-0)
Boron Nitride with a Twist Could Lead to New Way to Make Qubits
Achieving scalability in quantum processors, sensors, and networks requires novel devices that are easily manipulated between two quantum states. A team led by Berkeley Lab researchers has developed a method, using a solid-state “twisted” crystalline layered material, which gives rise to tiny light-emitting points that can be switched on and off with the simple application of an external voltage. The research could lead to a new way to make quantum bits, or qubits, which encode information in quantum computers.

Underwater glove puts octopus’ abilities on the hand of humans
Humans aren’t naturally equipped to thrive underwater. There are critical times when this becomes a liability. Rescue divers, underwater archeologists, bridge engineers, and salvage crews all use their hands to extract people and objects from water, and some of those removals suffer damage if subjected to an iron grip. Researchers at Virginia Tech working to solve this problem have developed an octopus-inspired glove capable of securely gripping objects underwater. They call it: Octa-glove.

Once the AIs cast their final votes, the XCA approach uses the vote tally to interpret what the most likely atomic structure is and to suggest how confident the researchers should be of the AI analysis. The AI analysis matches human effectiveness but takes just seconds.
