Imagine your company just discovered electricity. At first only a few machines run on it, and nobody worries about efficiency - consumption is low and the value is obvious. But once electricity becomes infrastructure, every process depends on it, and the question changes from can we use it?" to how efficiently are we using it?"...

The current narrative around artificial intelligence in the workplace is largely driven by Silicon Valley. But treating the tech sector as an island misses the actual trends in technology adoption-tech is just the first industry in line. As generative AI and automation tools mature, the shifts currently reshaping software engineering and product management will inevitably...

Andrew Haverdink, a tall grad student in a rain bib and rubber boots, wrenched a double-handed drill from the frozen soil that underlies much of Alaska's Denali National Park and then unclipped the hollow barrel from the end of the bit. He knelt in front of a blue tarp, lined the barrel up with a...

Generative AI models run on powerful chips known as GPUs, which depend on stacks of specialized memory chips packaged with the processor. To meet growing demand for memory, Samsung is building a massive new semiconductor manufacturing complex in Pyeongtaek, South Korea. Three fabs already operate around the clock, and a fourth is coming online. Construction...

In the fall of 2025, Jeff Dodge set up a six-foot folding table in the cafeteria of Cane Bay High School in Summerville, South Carolina, to conduct a taste test. When the first rush of about 150 hungry students hit, he was waiting with slow cookers filled with steaming marinara sauce and meatballs. Kids love...

I think I have good news about the nature of neural networks." With those simple words of optimism, Nick Cammarata, a researcher at the AI startup Goodfire, kicked off a 26,000-word blog post that has knocked the AI world on its head, sparking wild speculation as well as cautious (and not-so-cautious) celebration. Cammarata's claim is...

In the middle of an especially warm July in 2021, a wildfire ignited in a thick forest of black spruce and peeling paper birch trees on the northern campus of the University of Alaska, Fairbanks. The blaze, possibly sparked by lightning, burned across the dry carpet of feather mosses and lichen before climbing into the...

What do AI agents do if you don't tell them to do anything? The answer looks a lot like play. Researchers repeatedly stranded them alone on a virtual desert island for 30 hours in an experiment reminiscent of the movies Cast Away or Home Alone. The agents-copies of Claude Opus 4.7 nicknamed Eko-were able to...

More than 5 million people around the world have an advanced form of age-related macular degeneration (AMD) called geographic atrophy, in which cells in the retinas die off. And until now, no treatment could restore their vision. The PRIMA system, which was approved in Europe in July and is awaiting FDA clearance in the US,...

I. Meet cute Barnabas and Mainspring grew up near at hand, about an hour apart with good traffic, but for a long time they weren't close. They traded glimpses and occasional hellos and then went about their business. Both of them carried on livelier conversations with farther-flung neighbors, who were richer and had more to...

I don't remember much about Peppy, my first and only pet cat. I can conjure the sensation of stroking her while she purred, recall how she used to get stuck in trees (just like in cartoons!), and chuckle about the time she pooed in my baby sister's cot. That's about it. What I do vividly...

Social media bans are stacking up. In July, France joined Australia in restricting minors from accessing social media-barring children under 15 from major platforms, before the ban was blocked by the country's top court on human rights grounds. The UK aims to forbid kids under 16 from accessing Facebook, TikTok, and other platforms in early...

In this age of rising electricity demand, people are trying to squeeze every last bit of power out of every power plant possible. Over the past few weeks, there's been big news about nuclear power plants trying to do just that. Constellation, the largest nuclear operator in the US, announced plans to add nearly a...

Have you ever thought about what makes you you? Science assures us it has everything to do with the three-pound organ between our ears, with its billions of neurons and trillions of delicate connections. But it's a lot trickier to explain why we have a sense of self-awareness or to pin down precisely where that...

Pig kidneys that were cooled to -150 C and stored in a freezer for months have been successfully rewarmed and shown to work again for the first time, say scientists. They hope to replicate the findings with human organs. The kidneys-which are similar in size to human ones-were left in a glass-like state, in one...

Its call sign was Morphine 1-2. In February 2007, the hulking dual-rotor casualty evacuation helicopter had just flown three wounded soldiers to a field hospital in Balad, north of Baghdad, when another call came: an emergency mission to fly through an insurgent-controlled area in broad daylight. Typically, helicopters would be in a spot like...

When Keelan Miskell began winding down his crypto startup this year, he didn't think its data was worth much: the users were anonymous, the company just a few years old. But he's since turned the firm's digital archives into real money. He's netted roughly $25,000 for his code base and a still-pending amount (likely around...

Ever since people first seriously contemplated giving machines an intelligence modeled on our own, there has never been any question that they would, like us, be able to say no. The sci-fi canon is full of stories of robotic disobedience. Most of these capers are, of course, cautionary. But recently, the idea that AI shouldn't...

This week my colleague Antonio Regalado had an interesting update on GLP-1 weight-loss drugs. According to research presented at an aging meeting in Boston, these drugs seem to affect at least some measures of biological age. Overweight and diabetic people who take GLP-1s have a biological age around two to three years younger than similar...

For all the data that AI systems continually amass and analyze, enterprise AI agents often suffer from a curious shortcoming: a lack of knowledge. More than data, knowledge is the understanding of what the data means in the context of individual organizations. AI agents need this understanding to reason about situations, make decisions, and ultimately...
