It is impossible to make large language models fully secure against hacks because of a fundamental flaw in how they work, a team of researchers argue in a paper presented at the International Conference on Machine Learning, a top AI conference, this month. The claim has huge implications for the safety of this technology, which...

In June 2024, a small company called Zanskar purchased a geothermal power plant in New Mexico that was failing fast. The water coming from the underground reservoir was getting colder by the day, making the plant uneconomical to run. Now, two years later, that plant is running at full capacity again, thanks to a new...

It feels bad enough when an open letter signed by leading economists warns that AI might steal your job. The fact it may soon be better than you at making dinner? Insult to injury. But that's exactly what the company 1X promised when it showed off a pair of new, impressively dexterous (and, to some,...

Lee, an engineer at Samsung's semiconductor division, clocks out when his shift ends. He used to work longer hours, going the extra mile to excel at his projects. But lately, he's been coming straight home to work on his job application for the chipmaker's South Korean rival SK Hynix, sharing tips with his coworkers on...

Outside the small town of Paducah, Kentucky, a wealth of uranium is locked away in thousands of storage cylinders filled with waste material from a now-closed nuclear enrichment facility. Lasers could help get it out. A company called Global Laser Enrichment (GLE) is looking to reprocess this old material with a new technology called laser...

Imagine a healthcare system made up of multiple AI agents: one that manages symptom assessment, another scheduling, a third insurance, and a fourth pharmacy. Each is an expert in its domain. But they all have their own distinct knowledge and objectives. Today they can exchange data, but they are not yet able to actually coordinate...

Drug discovery is a high-cost, high-risk endeavor that is under growing pressure from a market increasingly defined by first-mover advantage. Since the 1950s, the cost of developing new pharmaceuticals has roughly doubled every nine years-a phenomenon known as Eroom's Law. Today, bringing a new drug to market takes an average of 10-15 years and costs...

For the enterprise, the promise of agentic AI is much more than just a better chatbot. It is software agents that execute business tasks end-to-end across people, business workflows, data, and systems. The platform best-suited to run agents is built with proper CPU capacity, resilient data access, policy-aware tool use, observability, memory management, and the...

This week, I covered a fascinating effort to preserve organs outside the body. There's a huge shortage of donor organs, and one of the main reasons is time-they survive only a matter of hours outside the body, even when they're kept on ice. Doctors dream of organ banks-stores of human organs that can be preserved...

When it comes to organ donation, time is everything. As soon as an organ has been carefully removed from a donor's body, it starts to deteriorate. Surgeons have a matter of hours to get it into a recipient. Leave it too long and the organ will become unusable. In most cases, organs will be kept...

Designing and developing a new medicine is an expensive, failure-prone scientific challenge. A new drug can take many years to develop, at the cost of a significant investment. And even then, most possible candidates never reach the patient. For biologic medicines, therapies made from engineered proteins rather than synthetic chemistry (which are often used to...

On July 3, as a heat wave swept the region, New York State's grid imported 52 gigawatt-hours of electricity from Canada-enough to meet about 9% of its total electricity demand that day. Some of that power shuttled in on a 339-mile power line stretching from Quebec to Queens called the Champlain Hudson Power Express (CHPE)....

When NASA's Nancy Grace Roman Space Telescope launches, as early as the end of next month, it will attempt one of astronomy's most precise disappearing acts to date. The telescope will carry the first space-bound active" coronagraph, an instrument that effectively erases most of the light from a star during photography. It will allow astronomers...

The conversation about AI often centers on algorithms, computing power, or huge investments in new semiconductor fabrication plants and hyperscale data centers. But beneath each of these advances is another layer of innovation that makes them possible: advanced materials. Every new generation of AI technology demands more processing power, more memory, greater energy efficiency, and...

The next time you apply for a job, AI may screen your resume before any human sees it. But there's good reason to question whether AI will judge you fairly. Researchers already know that LLMs pick up human biases from their training data. New research suggests that LLMs can also develop their own biases from...

Perimenopause has entered the chat. Perimenopause-and its better-known relative, menopause-used to be considered taboo. Not anymore, thanks at least in part to TV doctors and social media influencers. Perhaps it's my age, but these days, both my algorithm and my conversations with friends increasingly swing toward perimenopause. Menopause is defined as the life stage that...

Every morning, airline dispatchers, grid operators, and farmers around the world make decisions based on the same thing: a weather forecast.

It feels as if it should be illegal to even think about heating appliances during the height of summer-seriously, these heat waves in New York have been brutal-but we need to talk about heat pumps. The appliances use electricity for heating, they're incredibly efficient, and they're on the rise. (For what it's worth, many heat...

OpenAI has built an LLM super-hacker called GPT-Red that it uses as a sparring partner to help its other models boost their defenses against cyberattacks. Last week the company released the latest version of its flagship LLM, GPT-5.6. OpenAI says that training it against GPT-Red made the model its most robust release yet. GPT-Red automates...
