I read that a research team recently improved on optical tweezers by developing a technique to make them refrigerative such that individual atoms can be both cooled and manipulated. Opto-refrigerative… using a light cooling substrate and thermophoresis to move them. ------------------------------------------ Artificial General Intelligence List: AGI Permalink: https://agi.topicbox.com/groups/agi/Tace3f9aea35af378-M10b178a5baf7b93fab5b0d87 Delivery options: https://agi.topicbox.com/groups/agi/subscription
