Scientists have taken a major step toward ultra-secure quantum communication by demonstrating a remarkably stable quantum encryption system that worked across more than 120 kilometers of optical fiber. Using tiny semiconductor quantum dots that emit ...

A major obstacle may be standing in the way of the next generation of ultra-tiny computer chips. Researchers discovered that many promising 2D materials lose their advantages because an invisible atomic-scale gap forms when they are combined with ...

Physicists may have just cracked open a hidden side of the quantum world. For decades, every known particle was thought to belong to one of two categories -- bosons or fermions -- but researchers have now shown that bizarre "in-between" particles ...

Scientists may have uncovered a surprising secret behind why life exists at all. A new study suggests that the Universe's fundamental constants -- the deep physical rules that govern everything from atoms to stars -- appear to sit within an ...

A mysterious comet from beyond our solar system is giving astronomers a rare glimpse into alien worlds -- and it may have formed in a place far colder and stranger than anything around our Sun. The interstellar visitor, called 3I/ATLAS, contains an . ...

The Universe's biggest black holes may not be born giants after all. Scientists analyzing gravitational-wave signals from dozens of black hole collisions found evidence that the heaviest black holes are likely "cosmic recyclers" -- formed through ...

Astronomers using the James Webb Space Telescope have spotted something that shouldn't exist--at least not so early in the universe. A massive galaxy, formed less than 2 billion years after the Big Bang, appears to have no rotation at all, a trait .. ...

A bizarre planetary pairing 190 light-years away is challenging everything astronomers thought they knew about how worlds form. A "lonely" hot Jupiter -- typically found without nearby companions -- is sharing its system with a smaller mini-Neptune . ...

In a major breakthrough, scientists have experimentally confirmed a universal growth law in two dimensions using a quantum system of fleeting light-matter particles. The finding strengthens the idea that wildly different processes--from crystals to . ...

Cumberland, B.C. is reimagining its coal mining past as a clean energy opportunity. Water trapped in abandoned mine tunnels could be used in a geothermal system to heat and cool buildings efficiently and with minimal emissions. The project could ...
