A galaxy seen 13 billion years ago has just 1/240th the Sun’s oxygen abundance, offering a rare glimpse of what the ancestors of the Milky Way’s faintest neighbors may have looked like. Some of the faintest galaxies near the Milky Way may be survivors from the earliest chapters of cosmic history. Their ancient stars preserve […]

Nickel plays an important physiological role in plants, but how it is transported over long distances from stems and leaves to grains was poorly understood for more than 50 years. Now researchers have identified a key transporter gene, ZmNAET1, that controls nickel accumulation in cereal grains.
Magnons are quasiparticles that represent quantized spin waves in magnetic materials. They can carry information without moving electric charge, making them promising for future information technologies that could use less energy than conventional electronics. The frequency, stability and propagation distance of these waves are all important for their potential applications.
Drug-resistant bacteria are becoming more common worldwide, posing a major public health challenge. Addressing this problem requires finding new ways to eliminate bacteria, which in turn requires analyzing essential cellular processes that could serve as targets for future antibiotics.
Back in 1998, NASA’s Voyager 1 spacecraft became the farthest human-made object to ever travel beyond Earth. That technically means the intrepid explorer has been constantly breaking its own record for the last 18 years. But on November 18 (at 5:18 a.m. EST, to be exact), Voyager 1 will set a very specific and significant major record. At that point, it will officially be exactly one light-day away from its home planet. This means all future communications with the craft will take at least a full 24 hours to both send and receive. It’s a monumental achievement for a piece…
Apple TV’s new accessibility feature lets viewers turn on sign language interpretation within supported titles.
Google’s new tensor processing units (TPUs) broaden its chip portfolio to more use cases: confidential model training and more memory capacity.
In one of the biggest unenforced errors in the history of the AI industry, Nvidia CEO Jensen Huang admitted on Sunday that he had cheated on his wife with an alleged Chinese spy. The embarrassing news sent shares of the AI chipmaker — a bellwether for an economy overindexed on AI — plummeting, wiping out almost 30 percent of the company’s valuation. Nvidia’s board of directors has since launched an independent investigation into the billionaire’s affair, further clouding his grip on the company. Huang has no clear successor. Adding to the drama is the specter of divorce. Lori Huang, Jensen’s…
The remote access giant also urged its self-hosted customers to take down their own servers amid a “critical security incident,” fearing the possibility of cyberattacks.
