A Rail System Built From Single Atoms Could Make Superconductors Leak Less Energy
Japanese physicists show that naturally occurring, one-atom-high steps on a crystal surface can steer quantum vortices in an ultrathin superconductor more than a thousandfold more easily in one direction than another — a clean, tunable control mechanism that could inform future low-power superconducting electronics.

Deadly hospital fungus survives antifungal drugs by duplicating its whole genome, study finds
A lab accident led UK researchers to discover that Candida auris, a drug-resistant fungus behind lethal hospital outbreaks, can copy its entire genome to boost its odds of evolving resistance — a strategy the scientists call "bet-hedging."
China's Chang'e-6 moon rocks suggest a new explanation for the lunar far side's thick crust
Geochemical analysis of rock fragments retrieved from the moon's far side indicates that lateral flow inside an early, global ocean of molten rock — not a later impact — pushed material unevenly toward the two hemispheres, researchers report in a new study.
