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.

A NASA study suggests that traces of ancient life could be locked in Martian ice. Lab tests freezing bacteria under Mars-like radiation revealed amino acids can persist for tens of millions of years. Researchers say pure ice offers protection, making Mars’ frozen regions ideal for searching preserved biomolecules.
