Some dinosaurs could rise like giants until they grew too big
Two elephant-sized South American sauropods were unusually well built for standing on their hind legs. Digital tests showed that their robust femurs handled the enormous forces better than those of larger species, especially while the dinosaurs were young. The upright pose may have helped them reach treetops, frighten predators, or impress potential mates.
The mysterious hum heard around the world may finally have an explanation
The mysterious sound known as The Hum has been reported worldwide for decades, yet its source often remains impossible to find. Researchers tested whether people who hear it have exceptional low-frequency hearing or measurable sounds produced inside their ears, but neither explanation fit most participants. The strongest possibility is that many cases involve low-frequency tinnitus, even though the sound seems completely external.
An ordinary laptop solved a problem thought to require a quantum computer
A quantum problem once described as impossible for classical computers has now been solved using relatively modest hardware. Researchers used tensor networks to compress the overwhelming wave function created by hundreds of entangled qubits, allowing some calculations to run on a laptop. Their results matched both theoretical predictions and simulations performed with a quantum computer. The method could open new paths for exploring quantum dynamics and materials.
Alzheimer’s breakthrough: Scientists restore two hours of sleep without clearing brain plaques
Researchers have uncovered a surprising culprit behind sleep loss in Alzheimer’s disease: the brain’s own immune cells. In mice with amyloid plaques, overactive microglia triggered inflammation that kept the brain from getting enough deep, restorative sleep. Temporarily removing most of these cells restored more than two hours of sleep per day, even though the plaques remained unchanged.
UCLA scientists develop mineral sunscreen without the chalky white cast
Scientists have redesigned zinc oxide particles to create a mineral sunscreen that protects against ultraviolet radiation without leaving such a noticeable white cast. The SPF 30 formula could make sunscreen easier and more appealing to use across a wider range of skin tones.
Common antidepressant may ease long COVID’s crushing fatigue
A low-cost antidepressant may offer new hope for people struggling with long COVID fatigue. In a randomized clinical trial involving 399 adults, fluvoxamine significantly reduced fatigue and improved quality of life compared with a placebo, making it one of the first medications to show meaningful benefits for this disabling condition.
A tiny universe in a bottle reveals clues to the origins of life
Researchers have created cosmic dust from scratch by recreating space-like conditions inside glass tubes. The dust contains complex carbon-rich molecules built from elements essential to life and produces infrared signals similar to real material found in space. By studying these laboratory samples, scientists can explore how organic chemistry unfolds around stars and how comets, asteroids and meteorites may have carried those ingredients to Earth.
Scientists found two powerful new ways to destroy forever chemicals
Scientists are testing two promising ways to destroy PFAS, the stubborn “forever chemicals” that can accumulate in water and resist normal treatment. One method uses collapsing vapor bubbles to generate extreme heat and reactive molecules, while the other uses cold plasma and rising gas bubbles to pull PFAS to the surface and break them apart.
Scientists identify the rare meteorite that killed the dinosaurs 66 million years ago
The asteroid that wiped out the dinosaurs was likely an exceptionally rare CO chondrite from a distant region of the solar system. Its unusual chemistry suggests that planet-cooling dust and debris, rather than sulfur inside the asteroid, may have delivered the deadliest blow.
Your fingers may hold a secret of human brain evolution
A study of 225 newborns suggests prenatal estrogen may have played a role in the evolution of larger human brains. Boys with finger-length patterns linked to higher estrogen exposure before birth tended to have larger head circumferences, which are strongly associated with brain size. The same connection was not seen in girls.
Popular sugar substitutes linked to faster brain aging
Several popular sugar substitutes may not be as harmless as they seem. Adults who consumed the most artificial sweeteners showed substantially faster declines in memory and thinking, especially if they were under 60 or had diabetes. The highest intake was linked to cognitive aging roughly 1.6 years faster than the lowest intake. Researchers stressed that more studies are needed before concluding that sweeteners are the cause.
Earth’s biggest volcanic event transformed an entire oceanic plate
Seismic waves have revealed that the oceanic plate beneath the Ontong Java Plateau was dramatically transformed by the colossal volcanic activity that created it more than 100 million years ago. Researchers found a complex structure of horizontal layers cut through by vast swarms of vertical magma channels, along with unusually slow seismic waves suggesting that deep-rising magma chemically altered the plate itself.
