• Artificial intelligence boosts key Bose-Einstein experiment

  

  In a first, a team of physicists is using artificial intelligence (AI) to run a complex experiment to create an extremely cold gas trapped in a laser beam known as a Bose-Einstein condensate — thus replicating the experiment that won the 2001 Nobel Prize. Bose-Einstein condensates are some of the coldest places in the universe — far colder than outer space and typically less than a billionth of a degree above absolute zero. They can be used for mineral exploration or navigation systems as they ..

• Scientists have invented self-spooling 'liquid wire' that acts like spider silk

  

  Get right up close to a spider web, and you'll see some very particular properties: it stays taut in the wind, is really hard to break apart, and any flies coming into contact with it are trapped, rather than bouncing off it. Well, the same sticky substance that traps the flies also helps maintain tension in the web, and now scientists have come up with a way of replicating this in the lab – with a 'liquid wire' that exhibits many of the same properties of webs spun by spiders.  So why doesn't ..
