Researchers first confirmed altermagnetism as a distinct class of magnetism, then showed that modest pressure can tune its magnetic and electrical behavior. Together, the findings establish both the phenomenon and a possible control mechanism for future devices.
LHC experiments found that quark-gluon plasma can form in relatively small particle collisions, overturning the assumption that a large, long-lived fireball is required. The result gives physicists a more controlled setting for studying early-universe matter.
A new membrane separates crude oil at room temperature, potentially cutting refining energy use, emissions, and costs. Its importance now depends on whether it can remain durable and effective beyond laboratory tests.
Hera is examining how DART changed its asteroid target, while new modeling shows that nuclear deflection can vary sharply with an asteroid’s shape and impact angle. The week shifted planetary defense from demonstrating impact to planning around target-specific uncertainty.
Researchers are testing CRISPR treatment before birth, when it might prevent damage that becomes irreversible after delivery. The approach remains experimental and must resolve safety, consent, and long-term monitoring challenges.
Ryugu samples contain all five nucleobases used by DNA and RNA, strengthening the case that the early Solar System distributed life’s molecular ingredients widely. The finding supports asteroids as possible delivery vehicles but does not show that life formed in space.
