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 allows compact, sustainable archival storage. A 100-meter DNA tape could hold 36 petabytes, reshaping the future of data centers.

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.
