Scientists have created twisted laser beams that interact differently with right-handed and left-handed molecules, revealing their identity through the fragments they produce. The approach could provide a faster, simpler, and more sensitive way to ...
Sweden could become an important source of rare earth elements needed for magnets and green technologies. Instead of extracting one target metal, researchers are cataloging everything contained in Swedish mineral deposits. They will then develop ...
NASA is preparing for future astronaut landings on the Moon with an unusually ambitious orbital rehearsal. During Artemis III in 2027, Orion astronauts will rendezvous and dock separately with ...
Researchers discovered a proton-assisted mechanism that greatly improves how triplet energy moves between quantum dots and nearby molecules. The proton briefly shifts position, helps coordinate electron movement, and then returns to where it ...
A quantum problem once described as impossible for classical computers has now been solved using relatively modest hardware. Researchers used tensor networks to compress the overwhelming wave function created by hundreds of entangled qubits, ...
Scientists say new technologies have reopened the debate over whether Mars could someday be terraformed, turning a once impossible idea into a serious research topic. Before anyone tries to reshape the Red Planet, though, researchers say we must ...
A team of mathematicians used whimsical "silly sprinklers" to solve a physics mystery that has puzzled scientists for decades. Their experiments showed that the rotation of both normal and reverse ...
A new particle detector called PLATON could replace millions of tiny detector components with a single block of light-producing material. Using a light-field camera, highly sensitive photon sensors, and AI, it reconstructs particle paths in fast, ...
A new review highlights exciting progress in atomically thin quantum materials where light and magnetism work together in ways never before possible. In these materials, light-generated excitons can interact directly with magnetic behavior, creating ...
K2-18b is one of the most promising worlds for the search for extraterrestrial life, so astronomers conducted an unusually powerful radio survey using both the VLA and MeerKAT telescopes. Advanced ...
NASA's Perseverance rover has reached an impressive new milestone on Mars, completing the equivalent of a full marathon by driving 26.2 miles (42.195 kilometers) across the Red Planet. It accomplished the feat in just five years and four months, ...
NASA is ramping up its lunar ambitions by awarding nearly $600 million for four commercial Moon landings planned for late 2028. Each mission will carry the same trio of science instruments to improve lunar navigation, study dangerous dust kicked up ...
