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 single particles of light on demand, the team achieved one of the highest secure key rates yet for t

Astronomers have spotted something surprising in the far outer Solar System—a faint, short-lived atmosphere clinging to a tiny icy world that shouldn’t be able to hold one at all。 The object, called 2002 XV93, is far smaller than Pluto, yet observations during a rare stellar alignment revealed its presence through a subtle dimming of starlight。 Eve

Hubble has revealed a giant planet-forming disk unlike anything astronomers have seen before。 Nicknamed “Dracula’s Chivito,” the enormous structure appears turbulent and oddly lopsided, with towering filaments visible on only one side。 The disk contains enough material to potentially create multiple giant planets, making it a fascinating new labora

A new quantum-inspired algorithm has cracked a problem so massive that conventional supercomputers struggle to even approach it。 Researchers used the method to simulate extraordinarily complex quantum materials known as quasicrystals, opening the door to powerful new quantum devices and ultra-efficient electronics。 The work could help scientists de

A bold step toward returning humans to the Moon is underway with Blue Origin’s uncrewed MK1 “Endurance” lander, designed to test the technologies that future astronauts will rely on。 Built in partnership with NASA, the mission will showcase precision landing, autonomous navigation, and advanced cryogenic propulsion—key capabilities for operating on

Ocean heat plus human-caused global warming is a grim recipe for deadly climate extremes

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

A team at the University of Hong Kong has developed a new “super steel” that can survive the harsh conditions needed to make green hydrogen from seawater。 The material uses an unexpected double-protection mechanism that resists corrosion far better than conventional stainless steel。 Even more impressive, it could replace costly titanium parts used

Researchers in Japan traced a hidden medieval solar storm using ancient tree rings and centuries-old sky observations。 The team linked reports of eerie red auroras with spikes of carbon-14 trapped in buried wood, revealing a powerful solar radiation event around 1200 CE。 The findings suggest the Sun was far more active at the time, with unusually s

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 insulating layers。 That tiny gap weakens electronic performance and could prevent further miniaturizati

NASA’s Curiosity rover had an unexpectedly stubborn Mars souvenir after drilling into a rock nicknamed “Atacama” — the entire chunk ripped loose from the ground and stayed stuck to the rover’s drill。 Engineers watched as Curiosity shook, vibrated, tilted, and spun the drill over several days in an effort to free the rock, while cameras captured the

The little pauses, “ums,” and moments when you struggle to find the right word may reveal far more about your brain than anyone realized。 Researchers discovered that everyday speech patterns are closely tied to executive function — the mental system that powers memory, planning, focus, and flexible thinking。 By using AI to analyze natural conversat

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 tucked even closer to the star, a setup once thought nearly impossible

Layoffs are "not a savings-driven restructure," CFO says

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 called anyons could also exist in a one-dimensional system。 Even more exciting, these strange particles m

A new quantum physics study reveals that simply changing a magnetic field over time can unlock entirely new forms of matter that don’t exist under normal conditions。 By carefully “driving” materials with timed magnetic shifts, researchers created exotic quantum states that could be far more stable and resistant to errors—one of the biggest challeng

Made-up therapy referrals, incorrect prescriptions among the common mistakes

For nearly 100 years, reinforced rubber has powered everything from car tires to airplanes, yet scientists never fully understood why adding tiny particles of carbon black made rubber so incredibly strong。 Now, researchers at the University of South Florida have finally cracked the mystery using massive computer simulations that took the equivalent
