A new hollow nanoreactor mimics living cells to make hydrogen peroxide more efficiently using visible light。 Its light-trapping cavity and proton-shuttling shell could open new possibilities for cleaner chemical manufacturing and artificial photosynthesis
A new nanostructured carbon design lets fuel-cell catalysts use tiny amounts of platinum while remaining remarkably stable and efficient。 The breakthrough could help hydrogen fuel cells become a more practical way to power data centers, vehicles, and other energy-intensive technologies
Teens who start using cannabis may experience slower growth in memory, attention, language, and processing speed。 Their abilities often developed normally at first, then began leveling off while nonusers continued improving。 THC appeared to be the most likely driver, especially for worsening memory
Genetic changes may set off a chain reaction that causes the spine’s natural shock absorbers to harden and deteriorate。 Zebrafish with a faulty collagen-related gene developed mineral buildup and spinal fusion similar to human disc disease。 Researchers were able to reduce the damage using an existing osteoporosis drug and by targeting fat metabolis
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
More than 5,000 years after his death, Ötzi the Iceman is still hosting a remarkable mix of ancient and modern microorganisms。 Researchers separated microbes that lived in his body during his lifetime from those that arrived after his death, uncovering traces of his original gut bacteria and cold-loving yeasts that may have survived alongside him i
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
What was the thinking of the investors backing the now-canned plan, and are such proposals in the future inevitable
Andre Lavoie joined SpaceX in 2009 as an engineer, now he's looking to cash in his shares in the company
Yiyang Zhuge was already an intellectual celebrity in China。 Her viral interview with Christopher Nolan made her famous in the US—and quickly turned her into a political Rorschach test
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
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
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
The ruling is in addition to $375m in fines Meta was already ordered to pay in the case, for a total of $942m
In African tech hubs, developers are picking China’s cheap, freely available artificial intelligence models over more powerful U
A mathematician working at Anthropic says he used the AI model Claude Fable 5 to uncover a remarkably simple counterexample to the Jacobian conjecture, a famous problem that has resisted mathematicians for more than a century。 The result shows that the conjecture is false in three dimensions and above, although the original two-dimensional version
Plus: A judge rules cell tower dumps unconstitutional, water utility hacks spread to a dozen states, a phishing email opens a missile-parts supplier’s inbox, and a ransomware boss gets 16 years
Unitree Robotics wants to raise about $900 million in an I。 that tests market interest in humanoid robots, a technology that wows but has yet to prove its viability
