Time in a mini-universe, Arctic ice thickening, and a long-hidden Boston grave
This week’s science roundup highlights a Bose-Einstein condensate experiment where time emerges inside a mini-universe, NASA upgrading its ISS lab to study such quantum states, and other quantum advances including using quantum computers to create a fusion-relevant material; researchers also report a real-world attempt to thicken Arctic sea ice by flooding with seawater. Archaeology reveals one of the oldest graves of a free Black person in the U.S.—Sebastian, known as 'Boston,' who died in 1729 in Boston. In space news, China’s Tianwen-2 mission captured the first photo of Earth’s quasi-moon, hinting at future sample collection.
