An international team of astronomers, including researchers from the Department of Physics at The University of Hong Kong (HKU), has uncovered the first decisive evidence that at least some fast radio burst (FRB) sources—brief but powerful flashes of radio waves from distant galaxies—reside in binary stellar systems. This means the FRB source is not an isolated star, as previously assumed, but part of a binary stellar system in which two stars orbit each other.

Using the Five-hundred-meter Aperture Spherical Telescope (FAST) located in Guizhou, also known as the “China Sky Eye,” the team detected a distinctive signal that reveals the presence of a nearby companion star orbiting the FRB source.

““Spark plasma sintering or field assisted sintering technology (FAST) is not a common technique in industry yet. However, current ceramic manufacturers could pivot to making these materials by making small adjustments to existing processes and facilities.”

If you have a deep-seated, nagging worry over dropping your phone in molten lava, you’re in luck.

A research team led by materials scientists at Duke University has developed a method for rapidly discovering a new class of materials with heat and electronic tolerances so rugged that they that could enable devices to function at lava-like temperatures above several thousands of degrees Fahrenheit.

The world’s largest radio telescope began searching for signals from stars and galaxies and, perhaps, extraterrestrial life Sunday in a project demonstrating China’s rising ambitions in space and its pursuit of international scientific prestige. Beijing has poured billions into such ambitious scientific projects as well as its military-backed space program, which saw the launch of China’s second space station earlier this month.
