MIT researchers have designed a printable aluminum alloy that's five times stronger than cast aluminum and holds up at extreme temperatures. Machine learning helped them zero in on the ideal recipe in a fraction of the time traditional methods would take. When 3D printed, the alloy forms a tightly packed internal structure that gives it exceptional strength.

New Sapphire Wire, Could Transform, Aviation and Fusion Power. 'The Independent' reports that a new "sapphire fiber" could transform aircraft technology and potentially lead to breakthroughs in fusion power.

Assembling the wing from thousands of tiny identical pieces could make aircraft lighter and more energy efficient. How it works: The wing is made from an open, lightweight lattice framework that is covered with a thin layer of polymer material. It looks like thousands of matchstick-type struts welded together in small triangle shapes.
