Quantum PhysicsAliens could send quantum messages to Earth, calculations suggest
Scientists are developing quantum communications networks on Earth. Aliens, if they exist, could be going further.
-
Particle PhysicsHow physicists are probing the Higgs boson 10 years after its discovery
The famous particle may point to cracks in the standard model and new physics beyond.
-
‘Elusive’ profiles the physicist who predicted the Higgs boson
Peter Higgs, as Frank Close reveals in his new book, was just one of many physicists who helped crack the mystery of mass’s origins.
-
PhysicsPhysicists may have finally spotted elusive clusters of four neutrons
Long-sought clumps of four neutrons called tetraneutrons last less than a billionth of a trillionth of a second, an experiment suggests.
-
PhysicsHow fast a row of dominoes topples depends on friction
Computer simulations reveal that two types of friction are important in determining how quickly dominoes collapse.
-
PhysicsScientists created ‘smoke rings’ of light
A swirling doughnut of light shows that vortex rings aren’t just for fluids anymore.
-
Quantum PhysicsQuantum physics exponentially improves some types of machine learning
It wasn’t entirely clear if quantum computers could improve machine learning in practice, but new experiments and theoretical proofs show that it can.
-
Space50 years ago, the United States and Soviet Union joined forces for science
In 1972, U.S. and Soviet leaders agreed to work together on science. Now, Russia’s war in Ukraine is straining that decades-long partnership.
-
Particle PhysicsHow neutrinos could ensure a submarine’s nuclear fuel isn’t weaponized
Nuclear submarines could be monitored with the help of neutrinos to ensure that the fuel isn’t diverted to nuclear weapons programs
-
ComputingThe world’s fastest supercomputer just broke the exascale barrier
The Frontier supercomputer at Oak Ridge National Laboratory in Tennessee clocked in at more than 1.1 quintillion calculations per second.
-
ChemistryScientists made a Möbius strip out of a tiny carbon nanobelt
A twisted belt of carbon atoms joins carbon nanotubes and buckyballs in the list of carbon structures scientists can create.
-
PhysicsA galactic smashup might explain galaxies without dark matter
Scientists are debating whether a trail of galaxies reveals the origins of two weird dark matter–free galaxies.
