A new device concept opens the door to compact, high-performance transistors with built-in memory.

By enabling two chips to authenticate each other using a shared fingerprint, this technique can improve privacy and energy efficiency.

2025 was a year of reckoning, including how the heads of the top AI companies made promises they couldn’t keep. In this exclusive subscriber-only eBook, you’ll learn more about why we may need to readjust our expectations.

Twenty years ago, Joanna Wakefield-Scurr was having persistent pain in her breasts. Her doctor couldn’t diagnose the cause but said a good, supportive bra could help. A professor of biomechanics, Wakefield-Scurr thought she could do a little research and find a science-backed option. Two decades later, she’s still looking. Wakefield-Scurr now leads an 18-person team…

The bird is a beautiful silver-gray, and as she dies twitching in the lasernet I’m grateful for two things: First, that she didn’t make a sound. Second, that this will be the very last time.  They’re called corpse doves—because the darkest part of their gray plumage surrounds the lighter part, giving the impression that skeleton…

There’s a measles outbreak happening close to where I live. Since the start of this year, 34 cases have been confirmed in Enfield, a northern borough of London. Most of those affected are children under the age of 11. One in five have neededhospital treatment. It’s another worrying development for an incredibly contagious and potentially…

Just like each person has unique fingerprints, every CMOS chip has a distinctive "fingerprint" caused by tiny, random manufacturing variations. Engineers can leverage this unforgeable ID for authentication, to safeguard a device from attackers trying to steal private data.

A University of Hawaiʻi at Mānoa student-led team has developed a new algorithm to help scientists determine direction in complex two-dimensional (2D) data, with potential applications ranging from particle physics to machine learning. The research was published in AIP Advances.

One night in 2010, Mohit Gupta decided to try something before leaving the lab. Then a Ph.D. student at Carnegie Mellon University, Gupta was in the final days of an internship at a manufacturing company in Boston. He'd spent months developing a system that used cameras and light sources to create 3D images of small objects. "I wanted to stress test it, just for fun," said Gupta, who would begin his postdoctoral research at Columbia Engineering a few months later.

A new method developed at MIT could root out vulnerabilities and improve LLM safety and performance.

An AI control system co-developed by SMART researchers enables soft robotic arms to learn a broad set of motions once and adapt instantly to changing conditions without retraining.

By minimizing the need to drive around looking for a parking spot, this technique can save drivers up to 35 minutes — and give them a realistic estimate of total travel time.

More money has been invested in AI than it took to land on the moon. Spending on the technology this year is projected to reach up to $700 billion, almost double last year’s spending. Part of the impetus for this frantic outlay is a conviction among investors and policymakers in the United States that it needs to “beat China.” Indeed, headlines have long cast AI development as a zero-sum rivalry between the U.S. and China, framing the technology’s advance as an arms race with a defined finish line. The narrative implies speed, symmetry, and a common objective.But a closer look at AI development in the two countries shows they’re not only not racing toward the same finish line: “T..

AI-enabled deception now permeates our online lives. There are the high-profile cases you may easily spot, like when White House officials recently shared a manipulated image of a protester in Minnesota and then mocked those asking about it. Other times, it slips quietly into social media feeds and racks up views, like the videos that…

How uncrewed narco subs could transform the Colombian drug trade For decades, handmade narco subs have been some of the cocaine trade’s most elusive and productive workhorses, ferrying multi-ton loads of illicit drugs…

On a bright morning last April, a surveillance plane operated by the Colombian military spotted a 40-foot-long shark-like silhouette idling in the ocean just off Tayrona National Park. It was, unmistakably, a “narco sub,” a stealthy fiberglass vessel that sails with its hull almost entirely underwater, used by drug cartels to move cocaine north. The…

The United States and the European Union grew into economic superpowers by committing climate atrocities. They have burned a wildly disproportionate share of the world’s oil and gas, planting carbon time bombs that will detonate first in the poorest, hottest parts of the globe. Meanwhile, places like the Solomon Islands and Chad—low-lying or just plain…

By now, ChatGPT, Claude, and other large language models have accumulated so much human knowledge that they're far from simple answer-generators; they can also express abstract concepts, such as certain tones, personalities, biases, and moods. However, it's not obvious exactly how these models represent abstract concepts to begin with from the knowledge they contain.

It happens every day—a motorist heading across town checks a navigation app to see how long the trip will take, but they find no parking spots available when they reach their destination. By the time they finally park and walk to their destination, they're significantly later than they expected to be.

Researchers from the Department of Computer Science at Bar-Ilan University and from NVIDIA's AI research center in Israel have developed a new method that significantly improves how artificial intelligence models understand spatial instructions when generating images—without retraining or modifying the models themselves. Image-generation systems often struggle with simple prompts such as "a cat under the table" or "a chair to the right of the table," frequently placing objects incorrectly or ignoring spatial relationships altogether. The Bar-Ilan research team has introduced a creative solution that allows AI models to follow such instructions more accurately in real time.

The context of long-term conversations can cause an LLM to begin mirroring the user’s viewpoints, possibly reducing accuracy or creating a virtual echo-chamber.
