As Waymo deploys more driverless cars to 15 U。 cities and counting, its vehicles keep encountering new and unexpected situations that they have no script to handle

Deep underground, bacteria may be capable of doing something remarkable: trapping toxic uranium before it spreads。 When researchers fed microbes in uranium-contaminated mine water with glycerol, about 95% of the dissolved uranium disappeared within 130 days。 The bacteria helped convert it into an unusually stable uranium compound that had rarely be

Six deaths reported among screwworm cases, one directly attributed to the flies

The two men, users of the platform Kick, received suspended sentences and fines

More than 60,000 years ago, humans in southern Africa were engraving ostrich eggshells with intricate geometric patterns that appear far more organized than previously realized。 Researchers found recurring grids, parallel lines, right angles, and repeated shapes, suggesting the designs followed deliberate rules rather than being improvised。 The eng

Stress may literally scramble the brain’s internal GPS。 Researchers found that cortisol, a hormone released during stress, made people significantly worse at navigating a virtual environment and disrupted the precise activity of grid cells, specialized brain cells that help us understand where we are in space。 When landmarks were missing, this navi

A ten-month Antarctic experiment found that astronauts may struggle not only with loneliness but also with spending too much time around the same people。 Frequent contact was linked to greater tension and mistrust, while the crew increasingly divided into cultural and language-based groups

Metal-rich asteroids could one day become hardware stores for Mars, supplying the materials needed to build and repair a growing colony。 A new analysis shows that carefully selected asteroids may be reachable with current spacecraft technology。 Some could even provide the ingredients for making rocket fuel in space, dramatically reducing the burden

Minutes after four top researchers said they were leaving, Google said that Demis Hassabis, the Nobel-winning scientist who led the company’s A。 lab, was stepping into a new job

The tech giant is investing in the natural-gas-burning power plant as part of a huge data center in Texas, even as it pledges to honor climate commitments

As weather events become more extreme, fake videos are being shared rapidly online, and it’s causing real world problems in China

New AI toolbars and prompts are showing up in Google Docs and Gmail。 If you don’t want Gemini’s help in writing documents and emails, here’s how to turn that stuff off

The rise of the potato in the Andes appears to have left a lasting mark on human DNA。 Indigenous Peruvians carry exceptionally high numbers of a starch-digestion gene, likely because people with more copies gained an evolutionary advantage once potatoes became a staple food。 The change began thousands of years before European contact, providing unu

A total solar eclipse will plunge parts of Europe into darkness on August 12, 2026, with Spain offering some of the best views。 ESA will livestream the spectacle from the Javalambre Observatory, combining telescope feeds, drone footage, and expert commentary。 At 20:31 CEST, the observatory will experience 1 minute and 21 seconds of totality, reveal

Scientists have discovered incredibly tiny plasma whirlpools swirling across the Sun’s surface, some just 20 kilometers wide。 These previously invisible vortices may twist magnetic fields and help build up the energy released in small solar eruptions called nanoflares。 They may also help magnetic fields spread through the Sun’s atmosphere far faste

A 240-million-year-old reptile discovered in Brazil is revealing what evolution looked like just before the rise of dinosaurs and crocodiles。 The small predator had unusually positioned legs that may have allowed it to move more efficiently than many earlier reptiles。 Its close relatives were previously known mostly from other continents, suggestin

Two-thirds of an octopus’s neurons are in its arms—each operating independently—including the one it uses to have sex

There’s no perfect way to transfer possession of your digital assets to your loved ones after you’re gone。 But there are things you can do now to make the process easier for them

As data centers gobble up memory chips, other industries that need the components, including electronics companies like Apple and medical device makers, are asking for government help
