Quantum breakthrough could revolutionize teleportation and computing

16:37
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.

New quantum algorithm solves “impossible” materials problem in seconds

16:37
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 design advanced topological qubits and materials fo…

Scientists discover a mysterious silicone pollutant that may be everywhere

16:37
Researchers have uncovered unexpectedly high levels of silicone-based pollutants called methylsiloxanes floating through the atmosphere across cities, rural regions, and even forests. Much of the pollution appears to come from vehicle emissions, likely linked to engine oil additives that survive combustion and escape into the air. Scientists say humans may inhale more of these compounds daily tha…

This daily habit could lower dementia risk by 35%, scientists say

16:37
A huge long-term study found that drinking two to three cups of coffee a day was linked to a much lower risk of dementia, especially before age 75. Researchers say caffeine may help keep brain cells active while reducing inflammation and harmful plaque buildup associated with Alzheimer’s disease. But more coffee wasn’t better — the protective effect appeared to level off after moderate intake.

Cacti are evolving shockingly fast and scientists just learned why

16:37
Cacti may look like slow, stubborn desert survivors, but they’re actually evolving at lightning speed. Scientists studying more than 750 cactus species discovered that what really drives the explosion of new cactus species isn’t flower size or specialized pollinators, but how quickly cactus flowers change shape over time. The finding overturns a long-standing idea dating back to Darwin and reveal…

Your “um” and pauses could reveal early dementia risk

16:37
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 conversations, the team found they could predict cognitive…

Halley’s comet may be named after the wrong person

16:37
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 famous celestial event shown in the Bayeux Tapestry…

Humans returned to Britain 500 years earlier than scientists thought after the last ice age

16:37
Humans may have returned to Britain far earlier than scientists once believed — not long after the last ice sheet began retreating. New evidence suggests people were already moving into the British Isles around 15,200 years ago, tracking herds of reindeer and horses across a landscape that was suddenly becoming warmer and greener.

Scientists finally solve the 100-year mystery behind tough tires

16:37
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 of 15 years of computing time. They discovered t…

A rare cancer-fighting plant compound has been decoded

4:15
Scientists at UBC Okanagan have uncovered how plants produce mitraphylline, a rare natural compound with promising anti cancer potential. The team identified two enzymes that work together to build the molecule’s unusual twisted structure, solving a mystery that had puzzled researchers for years. Because mitraphylline appears only in tiny amounts in tropical plants like kratom and cat’s claw, the…

Scientists discover a weak spot shared by polio and common cold viruses

4:15
Scientists at the University of Maryland, Baltimore County, have uncovered a crucial trick used by enteroviruses—the group behind diseases like polio, myocarditis, encephalitis, and even the common cold—to reproduce inside human cells. The team captured, in unprecedented detail, how viral RNA recruits both viral and human proteins to assemble the machinery needed for replication, acting almost li…

Scientists make old blood stem cells young again in major anti-aging breakthrough

4:15
As blood stem cells age, their lysosomes become overactive and damaged, triggering inflammation and weakening the body’s ability to regenerate healthy blood and immune cells. By calming this cellular “overdrive,” researchers restored the stem cells’ youthful function, dramatically boosting their ability to regenerate and produce balanced blood cells.

New drugs could wipe out the “zombie cells” linked to cancer and aging

4:15
Researchers found a new way to kill harmful “zombie” cells that linger after chemotherapy and help cancers become more aggressive. These senescent cells survive by relying on a protective protein called GPX4, even while sitting on the edge of a deadly iron-triggered collapse. New drugs remove that protection, causing the cells to self-destruct. In mice, the approach reduced tumor size and boosted…

Scientists say this algae could remove microplastics from drinking water

12.května
Researchers created a special kind of algae that can grab microscopic plastic pollution out of water almost like a magnet. The algae produce limonene, an orange-scented oil that helps them bind to water-repelling microplastics, forming easy-to-remove clumps. As a bonus, the algae also clean wastewater while growing.

This strange giant dinosaur may change what we know about Jurassic titans

12.května
A bizarre new giant dinosaur discovered in Argentina is giving paleontologists a fresh look at how Jurassic titans evolved in the Southern Hemisphere. Bicharracosaurus dionidei stretched about 20 meters long and carried a strange mix of features seen in both Diplodocus and Brachiosaurus relatives. Scientists believe it could represent the first known Jurassic brachiosaurid from South America, hel…
