00:45 The biggest black hole jets ever seen

Astronomers have spotted a pair of enormous jets emanating from a supermassive black hole with a combined length of 23 million light years — the biggest ever discovered. Jets are formed when matter is ionized and flung out of a black hole, creating enormous and powerful structures in space. Thought to be unstable, physicists had theorized there was a limit to how large these jets could be, but the new discovery far exceeds this, suggesting there may be more of these monstrous jets yet to be discovered.

12:26 A sustainable, one-step method for alloy production

Making metal alloys is typically a multi-step process that creates huge amounts of emissions. Now, a team demonstrates a way to create these materials in a single step, which they hope could significantly reduce the environmental burdens associated with their production. In a lab demonstration, they use their technique to create an alloy of nickel and iron called invar — a widely-used material that has a high carbon-footprint. The team show evidence that their method can produce invar to a quality that rivals that of conventional manufacturing, and suggest their technique is scalable to create alloys at an industrial scale.
