Just like fashioning decorative shapes and figures using the Japanese art of folding paper, tracing when and where origami originated is complicated. But what cannot be disputed is its incredible influence in modern engineering. While styles of origami can be incredibly diverse, the art is rooted in mathematical principles that make it applicable to science and industry. This story in E&T mentions scientists at Georgia Tech exploring origami, kirigami (where paper is cut as well as folded) and specific folding techniques for building everything from furniture to bridges.
A pressing quest in the field of nanoelectronics is the search for a material that could replace silicon. Graphene has seemed promising for decades. But, its potential faltered along the way, due to damaging processing methods and the lack of a new electronics paradigm to embrace it.
A collaboration of physicists working at different institutes in the U.S. — including two at Georgia Tech — has discovered a new quantum state in an alloy made of magnesium, silicon, and tellurium, a press release said.
Toad tongues are ready for their closeup — extremely close closeups — in this video from San Francisco PBS station KQED. The closeups and slow-motion photography are necessary to show the role toad saliva plays in snatching crickets, worms, and other prey in the blink of an eye.
A tiny NASA moon probe continues to battle thruster issues as it attempts to reach its destination, but there's still time left to make a fix. Lunar Flashlight launched in December 2022 on a quest to seek lunar ice. But on the way to the moon, the cubesat experienced thruster glitches on its mission to test a new "green" propellant.
Scientists believe the Milankovitch cycles have influenced Earth's climate for millions of years, causing climate shifts such as ice ages and warmer periods. These cycles are the periodic variations that influence a planet's orbital properties.
Chia seeds sprouted in trays have experimentally confirmed a mathematical model proposed by computer scientist and polymath Alan Turing decades ago. The model describes how patterns might emerge in nature, such as desert vegetation, leopard spots and zebra stripes. But proving that Turing’s model explains patterns in the real world has been challenging.
