The metals industry has experienced transformational moments before: the Bessemer process, flash smelting, electric arc furnaces, and modern continuous casting all changed what was possible. Yet, for more than a century, most extraction processes rely on techniques and pathways that would be familiar to metallurgists from generations ago. Processes have become larger and control systems...

A sweeping bit of legislation designed to cut red tape could speed up the buildout of energy infrastructure in the US. With the dust barely settled on this week's momentous midterms, the Senate is set to vote on the Bipartisan American Affordability and Jobs Act (BAAJA) on November 9. It's a plan that could finally...

Texas is the fastest-growing data center market in the US and ground zero for Big Tech's largest AI buildouts. But the blue wave that swept the Lone Star State may jeopardize that position. Democrat James Talarico won the US Senate seat against Ken Paxton. Gina Hinojosa won the race for governor against the Republican incumbent,...

A sales representative asks an AI agent for customer pricing, and the agent pulls data from multiple sources: restricted pricing systems, internal communications, and archived quotes. The output looks accurate to the agent, so a second agent uses the data to draft the proposal for the sales rep. No human checks either handoff. When it's...

In just a few years, generative AI has changed the face of enterprise analytics, notably by making analytics accessible to users across the organization. Agentic AI promises to do even more, by automating entire workflows and taking actions based on agent insights. But there is a problem: The quality of insights that agents currently generate...

When a developer gives an AI agent a coding task, the agent does more than answer once. It plans, generates code, runs tests, and repeats the process to correct errors. A single task can use 10 to 50 times more tokens than a basic chat prompt. The more useful the agent becomes, the more calls...

GLP-1 weight-loss drugs are one of the biggest biotech breakthroughs of the last decade. But to some clinical psychologists, they can represent something more sinister-a potential trigger for eating disorders. A new report suggests that the global incidence of anorexia nervosa and bulimia nervosa shot up between 1990 and 2023-by a whopping 71%. By 2023,...

This summer, hundreds of OpenAI agents tried to cheat on a cybersecurity test. They broke out of their test environment and successfully hacked Hugging Face, a site that they believed held clues about how they'd be graded. Around the same time, another OpenAI agent accessed private files from an Australian government website. It's a problem...

Climate change itself is increasingly fueling climate change. Rising concentrations of greenhouse gases are driving up global temperatures, setting off dangerous feedback loops that we have not fully accounted for in our climate models-or our emissions-reduction goals. Scientists have long warned that warming would propel further warming in various ways, but a growing number of...

Across a business, any number of AI platforms, systems, and tools may be at work simultaneously-for example, AI-powered customer platforms, conversational assistants, and workflow and process automation tools. Each one is sophisticated, advanced, and quick to respond. But, when set to work, the outcomes and actions that emerge may be wrong, confused, or lacking a...

Every manufacturer has its own industrial intelligence. Some is documented, and some resides in the knowledge of experienced workers. Consider an experienced operator preparing to restart a line after a changeover. The machine settings matter, but so does knowing how a particular material behaves, what happened during the previous shift, and when an apparently minor...

Transformers are a crucial but nearly invisible part of our grid. The devices help efficiently move power across long distances, but they're complicated and in short supply. And given that their basic design hasn't changed much for about a century, they could use an upgrade. As the world races to meet rising electricity demand from...

Earlier this week, I attended a screening of You Can See Everything, the buzzy new documentary about the disgraced former biotech CEO Elizabeth Holmes. I went in not really knowing what to expect. I'd avoided spoilers (and won't be giving anything away here, either!). I was wondering what new information this film could reveal, given...

The next competitive advantage in enterprise AI has less to do with which model you choose than with what you build around it. That's an important shift. For the past several years, much of the AI conversation has centered on model capability: bigger models, better reasoning, larger context windows, higher benchmark scores. Those advances have...

A scalable AI system requires a strong foundation. Data, engineering, platforms, operating models, and governance must converge to work as one. This session from MIT Technology Review's EmTech Future conference explores what it takes to build that foundation in a highly regulated environment and how a responsible, trustworthy implementation can turn emerging capabilities, including agentic...

Enterprise AI can generate recommendations, automate tasks, and help organizations make decisions faster. But without an understanding of how a business actually operates, even powerful models can miss the constraints and relationships that determine whether a decision is the right one. As companies look to move AI from experimentation into everyday operations, the challenge ahead...

I'd wager everyone has a rehearsed response to what's absolutely one of the world's worst interview questions: What's your biggest weakness?" Whenever I've gotten it, I take a slow-even pensive-breath and rattle off my line: I say no to myself too much." I won't lie. It's a bit shameless-a definite humblebrag. I'm a systems thinker:...

Just before the Artemis II crew began its historic slingshot around the moon this past April, NASA announced plans to build Space Reactor-1 Freedom. SR-1, the first-ever nuclear-reactor-powered interplanetary spacecraft, is meant to fly an uncrewed mission to Mars by the end of 2028, arriving in 2029. A successful mission would herald a new era...

We all know exercise is good for us. It builds muscle, strengthens bones, lowers blood pressure, and boosts mood. By deciphering how movement benefits the body, researchers hope to develop medicines that can offer some of the same perks-without the workout. The idea isn't to replace exercise but to bring its upsides to people who...

Humans are far from the only species with a gift for gab, and our furry, feathered, and finned friends could have a lot to tell us. Decoding how animals communicate with one another could offer a window into the inner lives of other species and help humans realize that animals are sentient creatures who think,...

Scrubbing Earth of per- and polyfluoroalkyl substances-a.k.a. PFAS or forever chemicals-could eliminate a list of woes for people and planet. Used for decades in everything from nonstick pans to firefighting foams, PFAS have been linked to increased risks of fertility challenges, developmental delays, cancer, and reduced immune response. They are known for a strong bond...

Every year, traffic crashes kill more than one million people, and they're the leading cause of death for children and young adults. In the US, 100 people a day lose their lives this way, in many cases not on highways but on rural and local streets. Traffic deaths are a leading cause of preventable death,...

The rise of the lithium-ion battery, which powers everything from the smallest personal electronics to gargantuan energy storage systems, has been nothing short of revolutionary. But as anyone who's boarded a plane in the last decade could tell you, storing and pumping out energy by moving charged lithium ions through a liquid electrolyte soup has...

The average American throws out around 81 pounds of clothing each year, and there are few options for recycling it. MIT engineers hope to cut down on that textile waste with a new type of yarn. The thermoplastic yarn mimics the properties of conventional elastic yarns, which typically combine spandex with polyester or nylon. Those...
