A surprisingly simple change could make sodium-ion batteries far more powerful while opening the door to turning seawater into drinking water。 Researchers at the University of Surrey found that sodium vanadium oxide performs much better when its naturally occurring water is left inside instead of being removed during manufacturing
A person’s sleeping brain may reveal warning signs of dementia long before memory problems begin。 Researchers used machine learning to analyze EEG recordings from about 7,000 adults and found that an older-than-expected “brain age” was tied to a sharply higher dementia risk。 Every additional 10 years of brain aging raised that risk by nearly 40%
Ant parenting may have evolved from the same brain systems that once controlled hunger。 Researchers found that two chemical signals push clonal raider ants toward either caring for larvae or leaving to forage, with the balance changing as the ants grow older。 Similar signals are involved in mammalian caregiving, suggesting that evolution may have f
Once united in support of President Trump, right-wing influencers are embroiled in feuds and losing viewers, creating a problem for Republicans in the midterm elections
A gene involved in the brain’s overnight cleaning system may change how strongly poor sleep affects Alzheimer’s-related brain changes。 The findings point toward more personalized prevention strategies based on both genetics and sleep habits
A black hole observed during a dramatic 2023 eruption did not simply devour gas from its nearby companion star。 It also expelled large amounts of material through powerful jets and winds, even after the outburst had nearly faded。 The results suggest black holes may continue reshaping their surroundings long after their brightest fireworks end
More than 150 years after Darwin’s finches helped reshape biology, Galápagos plants are exposing another evolutionary surprise。 Giant daisies repeatedly developed similar heat-tolerant leaf shapes, but each lineage used a different combination of genes。 Researchers also found major genetic differences among isolated populations, suggesting new spec
Ultrafast X-rays revealed how a molecule converts absorbed light into motion in just trillionths of a second。 Individual atoms recorded different stages of the process, opening a powerful new window into light-driven chemistry
A new chemical process can transform three of the most common plastics into high-purity hydrogen without sorting them first。 The technique operates at much lower temperatures than traditional gasification and captures most of the plastic’s carbon in solid or liquid forms instead of releasing it as carbon dioxide
The Silicon Valley company’s costs rose more steeply than revenue growth, as it continues to invest heavily in artificial intelligence
Modern humans carry DNA from two mysterious extinct lineages in addition to Neanderthals and Denisovans。 Their hidden genetic legacy shows that our evolutionary past was shaped by repeated mixing among many different human groups
A combination of El Niño, unusually hot ocean waters, and jet stream changes is sending temperatures soaring in the US, Europe, and Asia
You can now buy panels that plug into electrical outlets, but there are some important safety issues to consider when picking and installing a system
The case against Pavel Durov reflected an ongoing fight over one of the world’s most popular messaging and media apps, which is widely used in the country
Physicists have uncovered a surprising limit to electrical resistance caused by particles colliding。 Using ultracold potassium atoms trapped in a grid of light, researchers created a highly controlled stand-in for electrons moving through a solid。 As collisions became more frequent and intense, resistance initially rose, but eventually hit a ceilin
Snapchat, YouTube, LinkedIn, and Substack are trying to combat the proliferation of fake AI content
NASA’s Swift Observatory observed a supermassive black hole ripping apart a star more than 30,000 light-years from the center of a distant galaxy。 The extraordinary flare briefly outshone its entire host galaxy in ultraviolet light and revealed a black hole about a million times the Sun’s mass
The term "Milwaukee Shoulder Syndrome" was coined in 1981, based on cases in four women
Viral tales of good triumphing over evil are racking up millions of views。 They’re almost entirely AI-generated clickbait
An appeals court in Canada acquitted Brandon Klayme of charges related to child sexual abuse imagery。 His Kik username had one less underscore than another account that was involved
