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...

Artist’s impression of an inhabited exoplanet. (NASA/Jay Freidlander)Given the Milky Way's age and size, we would expect to find intelligent civilizations scattered throughout. But where are they? A recent study suggests these civilizations might be so advanced that we simply can't detect them.Reevaluating the Detection of Extraterrestrial LifeIf extraterrestrials were observing Earth, they might...
(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...
