Jeff Dean, who for years was one of Google’s most important executives, is leading the new artificial intelligence company with the backing of Google
Researchers have found a way to build much larger “twisted” oxide materials while precisely controlling how their atomic layers line up。 Because these materials can be made over large areas and transferred onto different surfaces, the technique could help turn twistronics from a laboratory curiosity into a practical platform for next-generation ele
Stanford researchers discovered immune cells in flatworms that explode within minutes, killing nearby bacteria and foreign cells before vanishing completely。 Their unusually fast and localized attack could offer clues for developing targeted treatments against infections and cancer
Photons traveling through a cloud of atoms can emerge so early that they appear to have spent a negative amount of time inside。 Researchers tested whether this was merely a misleading feature of the light pulse by making extremely weak measurements of the atoms。 Surprisingly, the atoms confirmed the same negative dwell time
Vanderbilt researchers created the first selective compound designed to inhibit TAOK-1, a poorly understood protein connected to Alzheimer’s disease。 They also discovered a second compound that activates the entire TAOK protein family, offering scientists an unexpected new research tool。 Together, the compounds could reveal hidden disease mechanism
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
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%
A massive crocodilian capable of attacking dinosaurs has been brought back to life as the first scientifically accurate mounted skeleton of Deinosuchus schwimmeri。 The 31-foot replica at Georgia’s Tellus Science Museum was built from detailed fossil scans and more than 40 years of research by paleontologist Dr。 David Schwimmer, for whom the species
Taiwan’s steep, remote mountains have sheltered extraordinary forests containing hundreds of giant Taiwania firs。 After years of difficult expeditions, LiDAR mapping, and citizen-science detective work, researchers discovered an 84。1-meter (276-foot) tree, the tallest known in East Asia
Global warming appears to have shifted into a faster gear。 After removing the effects of El Niño, volcanic eruptions, and solar cycles, researchers found that the planet has warmed at roughly 0。35°C per decade over the past ten years, compared with just under 0
Coastal communities are facing a hidden threat that is making rising seas far more dangerous: the land beneath them is sinking。 New research shows that people in densely populated coastal regions experience an average relative sea-level rise of about 6 millimeters per year, nearly three times the global coastal average。 Groundwater pumping, oil and
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
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
A new 3D printing technique can produce exceptionally hard tungsten carbide cobalt while using less of its expensive raw materials。 By softening rather than fully melting the material, researchers created defect-free samples with industrial-grade hardness and opened the door to more efficient manufacturing
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
Fossilized dinosaur bones from Wyoming are offering a rare glimpse into the feeding behavior of Tyrannosaurus rex。 Researchers examined more than 3,000 bones dating back 72 to 66 million years and found just 12 with possible tooth traces, including four with patterns that closely matched the shape and spacing of T
Scientists have uncovered a surprising way that “jumping genes” may move between species and speed up evolution。 While these mobile genetic elements were thought to travel mainly inside viruses or plasmids, researchers found circular intron RNA from a tiny predatory bacterium inside the dead cells of another microorganism。 Because the RNA forms a s
