Famous for helping build Apple’s iPhones, Foxconn just suffered another cyberattack, highlighting the perils of warehousing some of the world’s most valuable data
A hacking group breached the academic software Canvas, used by thousands of schools and universities across the globe
Oak trees have a surprising trick to fight back against hungry caterpillars: they simply wait。 When trees are heavily attacked one year, they delay leaf growth by just three days the next spring—long enough to leave newly hatched caterpillars with nothing to eat。 This small shift slashes insect survival and reduces leaf damage by more than half, pr
The company said that it had identified, for the first time, hackers using artificial intelligence to discover an unknown bug。 The attempted attack represents “a taste of what’s to come,” one expert said
A little-known tree from Brazil’s Atlantic Forest may hold a surprising weapon against COVID-19。 Researchers discovered that compounds called galloylquinic acids, extracted from its leaves, can attack SARS-CoV-2 on multiple fronts—blocking the virus from entering cells, disrupting its replication, and even dampening harmful inflammation。 Unlike man
Dante’s Inferno may have been far more than a religious epic。 New research argues that the 14th-century poet essentially imagined a catastrophic asteroid impact centuries before modern science understood meteors。 In this interpretation, Satan crashes into Earth like a giant cosmic object, blasting through the Southern Hemisphere and reshaping the p
A strange kind of matter that “ticks” forever without energy input has just taken a major leap toward real-world use。 Known as a time crystal, this quantum system repeats its motion endlessly—like a clock that never winds down—and scientists have now managed to connect it to an external device for the first time。 By linking the time crystal to a ti
Researchers at Stanford have developed a compact optical amplifier that dramatically boosts light signals using very little power。 By recycling energy inside a looping resonator, the device achieves strong amplification with minimal noise and wide bandwidth。 Its efficiency and small size mean it could run on batteries and be integrated into consume
Scientists in Japan have developed a new way to instantly detect elusive quantum “W states,” a major milestone for quantum technology。 The breakthrough could help unlock faster quantum communication, teleportation, and powerful new computing systems
Early galaxy has elements produced by the Universe's first supernovae
“Every time I go to the dentist, I think about that guy,” researcher says
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 living systems—may all follow the same hidden rules
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 repeated smashups inside incredibly crowded star clusters。 These violent chain reactions appear to creat
A powerful new electromagnetic thruster has taken a major step forward after a successful high-energy test at NASA’s Jet Propulsion Laboratory。 Fueled by lithium vapor and driven by intense magnetic forces, the experimental engine reached record-breaking power levels—far beyond anything currently used in space。 Glowing hotter than molten lava and f
A medieval monk may have beaten Edmond Halley to one of astronomy’s greatest discoveries by nearly 700 years。 Researchers say Eilmer of Malmesbury recognized that the blazing comet seen in 1066 was the same one he had witnessed in 989。 At the time, comets were viewed as terrifying omens tied to war and royal deaths, adding even more drama to the fa
