When can we say AI made a scientific discovery? AI companies' insistence that their technology is making breakthroughs, not just aiding scientists, is making real progress harder to recognize. Last Wednesday, Anthropic announced that earlier this year it had launched a molecular biology lab, where Claude agents read and conjecture about hard biology problems and human scientists run experiments on what they report. And this AI-powered lab, the company said, had made its first discovery. To understand what Anthropic says its system did, imagine you're flipping through a library of millions of DNA sequences, amassed as scientists sequence more and more of the living world. One step toward a breakthrough might be finding a peculiar sequence that encodes an interesting enzyme, perhaps.

Top economic officials from China and the United States have begun talks in New York City aimed at clearing the way for possible agreements on trade, artificial intelligence and critical minerals ahead of a meeting between US President Donald Trump and Chinese President Xi Jinping later this week. US Treasury Secretary Scott Bessent and Chinese Vice Premier He Lifeng began talks at JPMorgan Chase's Manhattan headquarters on Sunday morning, with US Trade Representative Jamieson Greer also taking part. "I'm looking forward to having focused, fulsome and constructive talks today that will set the stage for our leaders' meeting," Bessent told reporters as he arrived. At the top of the agenda is a fragile US-China trade truce due to expire on November 10. The agreement, reached in Busan, South Korea, last November, capped US tariffs on Chinese goods at about 20 percent after a tit-for-tat trade fight briefly pushed tariffs into the triple digits.

OpenAI denied that the company had used work from rivals to solve the notoriously difficult puzzle. OpenAI denied that the company had used work from rivals to solve the notoriously difficult puzzle. OpenAI claims to have solved a major mathematics problem that has stumped humans for nearly a century after spending millions of dollars on the artificial intelligence-led endeavour. The company behind ChatGPT said it had cracked the Navier-Stokes problem, one of seven Millennium Prize Problems published by the Clay Mathematics Institute to highlight some of the biggest unsolved puzzles in the field. However, the announcement swiftly became mired in controversy after mathematician Tristan Buckmaster, a professor at New York University, said OpenAI accelerated its work on the problem after hearing that he and another researcher at Anthropic, an OpenAI rival, were poised to announce their own breakthrough.

Supercooled kidneys have been transplanted into pigs in a "landmark achievement" When it comes to organ donation, time is everything. As soon as an organ has been removed from a donor's body, it starts to deteriorate. Surgeons have only a matter of hours to get it into a recipient. In most cases, organs will be kept on ice during that time, at around 4 C (39 F). They cannot be frozen--in previous attempts, ice has formed, causing all kinds of damage.

The US government wants to get hold of a quantum computer good enough to contribute to scientific breakthroughs in just two years. It will use it to try to accelerate the research and development of new materials, pharmaceuticals and molecules useful in agriculture and manufacturing. Once a dream of theoretical physicists, quantum computers are now undoubtedly real, but have yet to prove unambiguously useful or to have broad commercial value. Their computational power depends on their size - how many components called qubits they comprise - and how reliable they are. Existing devices are still too small and too error-prone.

Science A.I.'s First Big Math Breakthrough Is Not What It Seems But it can help us do genuinely creative work--for a reason you might not expect.

Last month, OpenAI announced that its latest version of ChatGPT had solved a major math problem, one that had stumped experts for 80 years. This was considered among the most important unsolved problems in combinatorics, a prominent branch of math and computer science dealing with finite objects and arrangements. As opposed to previous A.I.-powered breakthroughs that involved back-and-forth conversations between a chatbot and a human expert, this was cracked with a single prompt.

Last week, OpenAI shocked the mathematical community by revealing that one of its internal artificial intelligence (AI) models had found a counterexample to a famous conjecture made by legendary Hungarian mathematician Paul Erdős in 1946. The planar unit distance problem, or Erdős problem 90, has intrigued mathematicians for decades. The new result is no mere curiosity. Canadian mathematician Daniel Litt described it as "the first result produced autonomously by an AI that I find interesting in itself". The breakthrough, produced with a general-purpose AI model rather than one specialised for mathematics, also highlights how AI is changing mathematical research itself.

The tech giant says a breakthrough in data-center networking has dramatically accelerated the flow of information through its massive cloud infrastructure. Amazon says it recently achieved a major breakthrough in networking design--and has been quietly deploying the new technology in its data centers since late last year. The company claims it has significantly increased data speeds while reducing energy use, potentially giving the tech giant an edge as companies race to build ever-faster systems in the cloud. The new technology hinges on a "quasi-random" design that combines elements of traditional, structured data networks with the performance advantages of more random architectures. Researchers have explored random networks for decades, but the technology has never been successfully scaled.
