Researchers have engineered a cobalt-nickel-vanadium alloy that stays tough even at –186°C, resisting the brittleness that plagues most metals in extreme cold. Using atomic-scale design, the team created dual structural patterns inside the alloy that block cracks and preserve ductility. In lab tests, the metal absorbed far more strain than conventional steels.
Astronomers now predict a 90% chance of detecting an exploding primordial black hole within a decade. Such an event would confirm Stephen Hawking’s theory that black holes evaporate, releasing a…
Researchers in China have developed a DNA “cassette tape” that stores data at densities far beyond current drives. By encoding digital files into DNA strands embedded on tape, the system…
