After Gioia had her first child with her then husband, he installed baby monitors throughout their Massachusetts home-to watch what we were doing," she says, while he went to work. She'd turn them off; he'd get angry. By the time their third child turned seven, Gioia and her husband had divorced, but he still found...

When OpenAI acquired Io to create the coolest piece of tech that the world will have ever seen," it confirmed what industry experts have long been saying: Hardware is the new frontier for AI. AI will no longer just be an abstract thing in the cloud far away. It's coming for our homes, our rooms,...

At first glance, it seems as if life teems around Carmen Suarez Vazquez's little teal-painted house in the municipality of Guayama, on Puerto Rico's southeastern coast. The edge of the Aguirre State Forest, home to manatees, reptiles, as many as 184 species of birds, and at least three types of mangrove trees, is just a...

Last fall, while attending a board meeting in Amsterdam, I had a few free hours and made an impromptu visit to the Van Gogh Museum. I often steal time for visits like this-a perk of global business travel for which I am grateful. Wandering the galleries, I found myself before The Courtesan (after Eisen), painted...

Back in February, I flew to Amsterdam to report on a high-stakes experiment the city had recently conducted: a pilot program for what it called Smart Check, which was its attempt to create an effective, fair, and unbiased predictive algorithm to try to detect welfare fraud. But the city fell short of its lofty goals-and,...

The race to build ever larger AI models is slowing down. The industry's focus is shifting toward agents-systems that can act autonomously, make decisions, and negotiate on users' behalf. But what would happen if both a customer and a seller were using an AI agent? A recent study put agent-to-agent negotiations to the test and...

In recent decades, cities have become increasingly adept at amassing all sorts of data. But that data can have limited impact when government officials are unable to communicate, let alone analyze or put to use, all the information they have access to. This dynamic has always bothered Sarah Williams, a professor of urban planning and...

Businesses in highly-regulated industries like financial services, insurance, pharmaceuticals, and health care are increasingly turning to AI-powered tools to streamline complex and sensitive tasks.Conversational AI-driven interfaces are helping hospitals to track the location and delivery of a patient's time-sensitive cancer drugs.

The best way to predict the future is to invent it," the famed computer scientist Alan Kay once said. Uttered more out of exasperation than as inspiration, his remark has nevertheless attained gospel-like status among Silicon Valley entrepreneurs, in particular a handful of tech billionaires who fancy themselves the chief architects of humanity's future. Sam...

Earlier this week, two new leaders of the US Food and Drug Administration published a list of priorities for the agency. Both Marty Makary and Vinay Prasad are controversial figures in the science community. They were generally highly respected academics until the covid pandemic, when their contrarian opinions on masking, vaccines, and lockdowns turned many...

The outbreak of covid-19 laid bare the vulnerabilities of global, interconnected supply chains. National lockdowns triggered months-long manufacturing shutdowns. Mass disruption across international trade routes sparked widespread supply shortages. Costs spiralled. And wild fluctuations in demand rendered tried-and-tested inventory planning and forecasting tools useless. It was the black swan event that nobody had accounted for,...

On May 6, 2010, at 2:32 p.m. Eastern time, nearly a trillion dollars evaporated from the US stock market within 20 minutes-at the time, the fastest decline in history. Then, almost as suddenly, the market rebounded. After months of investigation, regulators attributed much of the responsibility for this flash crash" to high-frequency trading algorithms, which...

Lithium-ion batteries have some emerging competition: Sodium-based alternatives are starting to make inroads. Sodium is more abundant on Earth than lithium, and batteries that use the material could be cheaper in the future. Building a new battery chemistry is difficult, mostly because lithium is so entrenched. But, as I've noted before, this new technology has...

Last year, a humanoid warehouse robot named Digit set to work handling boxes of Spanx. Digit can lift boxes up to 16 kilograms between trolleys and conveyor belts, taking over some of the heavier work for its human colleagues. It works in a restricted, defined area, separated from human workers by physical panels or laser...

This week, I've been thinking about the powerful connection between mind and body. Some new research suggests that people with heart conditions have better outcomes when they are more hopeful and optimistic. Hopelessness, on the other hand, is associated with a significantly higher risk of death. The findings build upon decades of fascinating research into...

Later this month, an inconspicuous 150-kilogram satellite is set to launch into space aboard the SpaceX Transporter 14 mission. Once in orbit, it will test super-accurate next-generation satnav technology designed to make up for the shortcomings of the US Global Positioning System (GPS). The satellite is the first of a planned constellation called Pulsar, which...

Last year, China saw a boom in foundation models, the do-everything large language models that underpin the AI revolution. This year, the focus has shifted to AI agents-systems that are less about responding to users' queries and more about autonomously accomplishing things for them.
