Friday Squid Blogging: New SQUID

There’s a new SQUID:

A new device that relies on flowing clouds of ultracold atoms promises potential tests of the intersection between the weirdness of the quantum world and the familiarity of the macroscopic world we experience every day. The atomtronic Superconducting QUantum Interference Device (SQUID) is also potentially useful for ultrasensitive rotation measurements and as a component in quantum computers.

“In a conventional SQUID, the quantum interference in electron currents can be used to make one of the most sensitive magnetic field detectors,” said Changhyun Ryu, a physicist with the Material Physics and Applications Quantum group at Los Alamos National Laboratory. “We use neutral atoms rather than charged electrons. Instead of responding to magnetic fields, the atomtronic version of a SQUID is sensitive to mechanical rotation.”

Friday Squid Blogging: Squid Proteins for a Better Face Mask

Researchers are synthesizing squid proteins to create a face mask that better survives cleaning. (And you thought there was no connection between squid and COVID-19.) The military thinks this might have applications for self-healing robots.

Friday Squid Blogging: China Closing Its Squid Spawning Grounds

China is prohibiting squid fishing in two areas — both in international waters — for two seasons, to give squid time to recover and reproduce.

This is the first time China has voluntarily imposed a closed season on the high seas. Some experts regard it as an important step forward in China’s management of distant-water fishing (DWF), and crucial for protecting the squid fishing industry. But others say the impact will be limited and that stronger oversight of fishing vessels is needed, or even a new fisheries management body specifically for squid.
