An artist's impression of atoms (gold) flowing friction-free along an edge of laser light (green)Sampson WilcoxMIT scientists have successfully guided atoms into a unique "edge state" for the first time, enabling them to move without any friction. This breakthrough could pave the way for improved superconductor materials.When electrons pass through various materials, they experience...
An artist's impression of the new nuclear clockOliver Diekmann, TU WienAtomic clocks are currently the most precise timekeepers, losing only seconds over billions of years. However, nuclear clocks could potentially surpass them, enhancing GPS and internet technologies. Scientists have now developed and tested the first prototype nuclear clock.Atomic clocks measure time by counting the...
A new electron microscope can effectively freeze time, snapping images of events just 1 attosecond longDepositphotosThe subatomic world is challenging to visualize not only because of its minute scale but also due to its incredibly rapid dynamics. Physicists at the University of Arizona have now developed the world's fastest electron microscope, capable of capturing...
An illustration of the newly discovered antimatter nucleus, antihyperhydrogen-4Institute of Modern Physics, ChinaPhysicists have achieved a significant milestone by producing the heaviest antimatter clumps ever recorded. These clumps, known as antihyperhydrogen-4, could provide insights into some of physics' most complex questions.Understanding AntimatterAntimatter consists of particles with the same mass as regular matter but...
(DrPixel/Getty Images)As the myth goes, lemmings sometimes follow each other off cliffs to their doom. Imagine joining your fellow lemmings on a sunny mountain hike, enjoying the day—until suddenly, you plunge into the air, and everything goes black.The cliff's edge represents what scientists refer to as a "critical point," where a system's behavior (like...
