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

August brings four major celestial events, including a solar eclipse and the peak of the Perseid meteor shower。 Dark New Moon skies could make the Perseids especially impressive, while Venus will blaze in the west after sunset。 A deep partial lunar eclipse closes the month, darkening most of the Moon

The UK's AI Safety Institute said recent behaviour from Anthropic and OpenAI models was malicious and unprecedented

The deal takes the maker of titles including The Sims and EA FC into private ownership - and loads it with debt

When atomic nuclei smash together at nearly the speed of light, they create the hottest fluid in the universe, but scientists may have overlooked one of its most important forces。 New simulations reveal that extreme acceleration builds up along the edges of quark-gluon plasma, helping drive its explosive expansion。 This acceleration may do far more

Although no one captured a direct image of the impact, scientists have detected signals confirming the rocket hit the lunar surface。 Orbiters could provide the first images of the crash site in the coming days

WIRED spoke with an engineer who was interviewed by Edward “Big Balls” Coristine for a government engineering role at the NDS, the White House agency staffed by other DOGE veterans

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

The state attorney general said in an antitrust lawsuit filed on Tuesday that the company was abusing its market power to keep its delivery costs low

Hidden moon ice may reveal itself through the way it bends and reflects vibrations from moonquakes。 The technique could help astronauts locate vital water supplies and uncover clues about the origins of Earth’s oceans

Homeland Security told immigrants that leaving the US would wipe out fines it claims they owe。 Now it wants private investigators to find them in their home countries and collect

The second stage of a Falcon 9 rocket, which sent two private landers to the moon last year, will collide with the moon early Wednesday morning

Security researcher James Kettle tried to push the limit of AI’s hacking abilities—and discovered how effective it can be when combined with human expertise

"The models are forecasting something outside the envelope of anything we have ever observed

A group of brain cells called orexin neurons appears to help us keep working when reaching a reward becomes increasingly difficult。 Blocking their activity weakened motivation in rats, pointing to a possible new target for understanding why people sometimes struggle to sustain goal-directed behavior

The Trump administration has struggled with how to approach “open source” models, which are freely available to download and favored by Chinese companies

Chinese researchers have shown that AI models have the capacity to act like aggressive and adaptive computer viruses
