Why passkey apps treat Windows differently than other operating systems
Meta has been trailing competitors。 Zuckerberg thinks he's found a way forward
Scientists have built the first all-optical photonic time crystal, allowing them to reshape the behavior of terahertz light at extraordinary speeds。 The breakthrough could open the door to ultrafast computing, smarter communication systems, advanced imaging, and a new generation of highly tunable lasers
fMRI scans show happiness, fear, anger, and sadness have distinct brain activity patterns in doggy brains
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
Scientists traced a mysterious surge of low-energy gamma rays from zinc-70 to magnetic changes occurring inside its nucleus。 The breakthrough could improve models of how stars, supernovae, and neutron star mergers create heavy elements
Zuckerberg’s superyacht and support ship were slow to heed Coast Guard call
Trump falsely claimed the MMR vaccine is "quite lethal" and linked shots to autism
Engineers have transformed a notoriously brittle cobalt-aluminum compound into a material that is both extremely strong and capable of bending without breaking。 Their nanoscale design produced a yield strength about six to 10 times greater than high-strength structural steel while sustaining substantial deformation at room temperature。 The approach
New update includes improvements for the Intel-based MSI Claw 8 EX AI+ among others
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
Scientists have identified LHAASO J1912+1014u as a cosmic accelerator that can push protons beyond one quadrillion electron volts。 The finding may help reveal where the Milky Way’s most energetic cosmic rays come from and how they influence the galaxy
Trump has resisted urge to fire FCC Democrat despite recent Supreme Court win
Chemists have developed a catalyst that breaks a long-standing rule governing which molecules receive electrons during chemical reactions。 By releasing electrons directly into solution, the technique could unlock reactions—and potentially useful new molecules—that were previously out of reach
Scientists have successfully generated electricity with a hydrogen turbine that produces its own pressure through detonation waves instead of relying on a mechanical compressor。 The breakthrough could unlock dramatically more efficient power systems for clean energy and future aviation
A reminder of the perils of digital ownership
FDA report finally reveals where Taylor Farms sent its lettuce—and it raises questions
Companies treat some email domains as digital trash cans, despite the risks
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
