Cave deposits show surprising shift in permafrost over the last 400,000 years

Nearly one quarter of the land in the Northern Hemisphere, amounting to some 9 million square miles, is layered with permafrost—soil, sediment, and rocks that are frozen solid for years at a time. Vast stretches of permafrost ...

Scientists harness molecules into single quantum state

Researchers have big ideas for the potential of quantum technology, from unhackable networks to earthquake sensors. But all these things depend on a major technological feat: being able to build and control systems of quantum ...

Team makes single photon switch advance

The ability to turn on and off a physical process with just one photon is a fundamental building block for quantum photonic technologies. Realizing this in a chip-scale architecture is important for scalability, which amplifies ...

Scientists see chemical short-range order in medium-entropy alloy

Chinese scientists have made direct observations of face-centered cubic VCoNi (medium)-entropy alloys (MEA) and for the first time proposed a convincing identification of subnanoscale chemical short-range order (CSRO). This ...
