In the absence of light from the first stars and galaxies, the universe entered a period known as the cosmic dark ages. The first stars and galaxies appeared several hundred million years later and began burning away the hydrogen fog left over from the Big Bang, rendering the universe transparent, like it is today. Researchers have now confirmed the existence of a distant, faint galaxy typical of those whose light burned through the hydrogen atoms; the finding should help them understand how the cosmic dark ages ended.]]> Thu, 01 Jun 2023 21:57:42 +0200 https://api.follow.it/track-rss-story-click/v3/sduNxuvlnXOOtPhlmL2W5ClmFkX7M1Jw https://api.follow.it/track-rss-story-click/v3/sduNxuvlnXOOtPhlmL2W5OT5HJgy6HUf Researchers demonstrated that it's possible to make carbon dioxide capture filters using 3D printing.]]> Wed, 31 May 2023 21:01:50 +0200 https://api.follow.it/track-rss-story-click/v3/sduNxuvlnXOOtPhlmL2W5OT5HJgy6HUf https://api.follow.it/track-rss-story-click/v3/sduNxuvlnXMyhHY-5Zu4xl1cWWor9YPv Rare earth elements, like neodymium and dysprosium, are a critical component to almost all modern technologies, from smartphones to hard drives, but they are notoriously hard to separate from the Earth's crust and from one another. Scientists have discovered a new mechanism by which bacteria can select between different rare earth elements, using the ability of a bacterial protein to bind to another unit of itself, or 'dimerize,' when it is bound to certain rare earths, but prefer to remain a single unit, or 'monomer,' when bound to others.]]> Wed, 31 May 2023 21:01:25 +0200 https://api.follow.it/track-rss-story-click/v3/sduNxuvlnXMyhHY-5Zu4xl1cWWor9YPv https://api.follow.it/track-rss-story-click/v3/sduNxuvlnXMyhHY-5Zu4xqCY3L745TL_ Scientists have taken the world's first X-ray SIGNAL (or SIGNATURE) of just one atom.
