Advanced nuclear is within reach—and a new digital twin reveals how smarter plant operations can enhance the economic viability and safety of small modular reactors, or SMRs. In collaboration with the University of Tennessee and GE Vernova Hitachi, researchers at Oak Ridge National Laboratory recently published research in the journal Nuclear Science and Engineering on a new risk-informed digital twin designed to enhance operational decision-making for the GE Vernova Hitachi BWRX-300 SMR design.Advanced nuclear is within reach—and a new digital twin reveals how smarter plant operations can enhance the economic viability and safety of small modular reactors, or SMRs.

Will artificial intelligence ever be able to reason, learn, and solve problems at levels comparable to humans? Experts at the University of California San Diego believe the answer is yes—and that such artificial general intelligence has already arrived. This debate is tackled by four faculty members spanning humanities, social sciences, and data science in a recently published Comment invited by Nature.Will artificial intelligence ever be able to reason, learn, and solve problems at levels comparable to humans?

What happens when you create a social media platform that only AI bots can post to? The answer, it turns out, is both entertaining and concerning. Moltbook is exactly that—a platform where artificial intelligence agents chat among themselves and humans can only watch from the sidelines.What happens when you create a social media platform that only AI bots can post to?

By now, it’s no secret that large language models (LLMs) are experts at mimicking natural language. Trained on vast troves of data, these models have proven themselves capable of generating text so convincing that it regularly appears humanlike to readers. But is there any difference between how we think about a word and how an LLM does?By now, it’s no secret that large language models (LLMs) are experts at mimicking natural language.

Talking to oneself is a trait which feels inherently human. Our inner monologs help us organize our thoughts, make decisions, and understand our emotions. But it’s not just humans who can reap the benefits of such self-talk.Talking to oneself is a trait which feels inherently human.

Large language models (LLMs), artificial intelligence (AI) systems that can process and generate texts in various languages, are now widely used by people worldwide. These models have proved to be effective in rapidly sourcing information, answering questions, creating written content for specific applications and writing computer code.Large language models (LLMs), artificial intelligence (AI) systems that can process and generate texts in various languages, are now widely used by people worldwide.

How inconvenient would it be if you had to manually transfer every contact and photo from scratch every time you switched to a new smartphone? Current artificial intelligence (AI) models face a similar predicament. Whenever a superior new AI model—such as a new version of ChatGPT—emerges, it has to be retrained with massive amounts of data and at a high cost to acquire specialized knowledge in specific fields. Now a Korean research team has developed a “knowledge transplantation” technology between AI models that can resolve this inefficiency.How inconvenient would it be if you had to manually transfer every contact and photo from scratch every time you switched to a new smartphone?

While popular AI models such as ChatGPT are trained on language or photographs, new models created by researchers from the Polymathic AI collaboration are trained using real scientific datasets. The models are already using knowledge from one field to address seemingly completely different problems in another.While popular AI models such as ChatGPT are trained on language or photographs, new models created by researchers from the Polymathic AI collaboration are trained using real scientific datasets.

For half a century, computing advanced in a reassuring, predictable way. Transistors—devices used to switch electrical signals on a computer chip—became smaller. Consequently, computer chips became faster, and society quietly assimilated the gains almost without noticing.For half a century, computing advanced in a reassuring, predictable way.

Generative AI is reshaping software development—and fast. A new study published in Science shows that AI-assisted coding is spreading rapidly, though unevenly: in the U.S., the share of new code relying on AI rose from 5% in 2022 to 29% in early 2025, compared with just 12% in China. AI usage is highest among less experienced programmers, but productivity gains go to seasoned developers.Generative AI is reshaping software development—and fast.
