阅读全文Scientists have, for the first time, successfully studied liquid carbon in the lab by combining a powerful high-performance laser with the European XFEL x-ray laser. The experiment captured fleeting nanosecond snapshots of carbon as it was compressed and
阅读全文Hubble’s latest image captures a glittering star cluster inside the Large Magellanic Cloud, a dwarf galaxy about 160,000 light-years from Earth. This region, known as N11, is one of the galaxy’s largest stellar nurseries where vast clouds of gas and dust
阅读全文For the first time, scientists have observed electrons in graphene behaving like a nearly perfect quantum fluid, challenging a long-standing puzzle in physics. By creating ultra-clean samples, the team at IISc uncovered a surprising decoupling of heat and
阅读全文For centuries, people believed ice was slippery because pressure and friction melted a thin film of water. But new research from Saarland University reveals that this long-standing explanation is wrong. Instead, the slipperiness comes from the subtle inte
阅读全文Mars’ Jezero Crater holds signs of ancient water and strange mineral reactions, some linked with organic compounds. With Perseverance’s samples and AI-refined mineral maps, scientists are closing in on whether Mars once had the chemistry needed for life.
阅读全文For centuries, scientists have puzzled over globular clusters, the dense star systems that orbit galaxies without dark matter. Using ultra-detailed simulations, researchers recreated their origins and unexpectedly revealed a new class of cosmic object tha
阅读全文Physicists have achieved a breakthrough by using a 58-qubit quantum computer to create and observe a long-theorized but never-before-seen quantum phase of matter: a Floquet topologically ordered state. By harnessing rhythmic driving in these quantum syste
阅读全文Scientists have finally unlocked a way to identify the elusive W state of quantum entanglement, solving a decades-old problem and opening paths to quantum teleportation and advanced quantum technologies.
阅读全文Quantum materials, defined by their photon-like electrons, are opening new frontiers in material science. Researchers have synthesized organic compounds that display a universal magnetic behavior tied to a distinctive feature in their band structures call
