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
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
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
Astronomers may have been listening for alien civilizations in only a small slice of the radio spectrum while overlooking a largely unexplored range of higher frequencies。 Using archived data from the ALMA telescope in Chile, researchers conducted the observatory’s first SETI survey, searching for narrow signals that could indicate advanced technol
The company recently raised prices on a number of products because of component supply shortages caused by the artificial intelligence boom
A new cooking method could make French fries crispier in less time while significantly limiting how much oil they absorb。 Researchers propose combining microwave heating, which keeps oil out, with conventional frying, which provides the crunch consumers expect
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
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
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
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
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
New EU rules stipulate that people must be told when they’re interacting with AI or looking at AI-generated or -edited content, leading to fear of “disclosure fatigue
The Silicon Valley company’s costs rose more steeply than revenue growth, as it continues to invest heavily in artificial intelligence
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
Snapchat, YouTube, LinkedIn, and Substack are trying to combat the proliferation of fake AI content
NASA astronaut Chris Williams and two Roscosmos cosmonauts are back on Earth after spending 241 days aboard the International Space Station。 Their journey covered more than 102 million miles and included 3,856 trips around the planet
The term "Milwaukee Shoulder Syndrome" was coined in 1981, based on cases in four women
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
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
Primordial black holes may occasionally pass through white dwarf stars and trigger enormous Type Ia supernova explosions。 Researchers found that these events could explain chemical patterns seen in supernova remnants, nearby explosions, and stars across the Milky Way
