Physics-informed neural networks (PINNs) have emerged as a promising framework to develop complex scientific surrogate models, yet their scalability and accuracy often degrade in non-canonical geometries, such as non-rectangular domains or three-dimensional (3D) domains with high aspect ratios. These limitations hinder the broader adoption of vanilla PINNs in real-world, practical systems. In this work, we introduce a multi-domain PINN (MDPINN) framework designed to address the scalability and generalization challenges inherent in 3D non-rectangular domains governed by nonlinear fluid dynamics. The target domain consists of intersecting 3D fluid channels with a high aspect ratio, inducing complex flow features such as deflections, mixing, and recirculations. Our approach is grounded in two key innovations: 1) domain decomposition, which partitions the channel volumes into multiple cubic-like subdomains, each modeled by an individual PINN, 2) enforcement of global dynamics (MDPINN-GD), which ensures that the total mass flow rate entering the domain equals that exiting. These innovations reduce the complexity of the problem imposed on individual PINNs and guide effective network optimization toward physically consistent solutions throughout the domain. We demonstrate that our method achieves: 1) 74.8\% accuracy improvement over a single-network PINN, and 2) 52.9\% accuracy improvement over MDPINN that do not enforce global mass conservation. Furthermore, the MDPINN-GD framework exhibits accurate prediction even in highly complex regions-such as the channel intersecting zone and the outlet zone characterized by intense flow mixing and large velocity gradients-achieving maximum normalized mean absolute errors below 14.9\% for velocity predictions compared to simulation results. This work establishes a path towards scalable, physically grounded surrogate modeling approach that is extensible to multiphysics and high-dimensional scientific problems.

Artificial intelligence (AI) now permeates critical infrastructures and decisionmaking systems where failures produce social, economic, and democratic harm. This position paper challenges the entrenched belief that regulation and innovation are opposites. As evidenced by analogies from aviation, pharmaceuticals, and welfare systems and recent cases of synthetic misinformation, bias and unaccountable decision-making, the absence of well-designed regulation has already created immeasurable damage. Regulation, when thoughtful and adaptive, is not a brake on innovation--it is its foundation. The present position paper examines the EU AI Act as a model of risk-based, responsibility-driven regulation that addresses the Collingridge Dilemma: acting early enough to prevent harm, yet flexibly enough to sustain innovation. Its adaptive mechanisms--regulatory sandboxes, small and medium enterprises (SMEs) support, real-world testing, fundamental rights impact assessment (FRIA)--demonstrate how regulation can accelerate responsibly, rather than delay, technological progress. The position paper summarises how governance tools transform perceived burdens into tangible advantages: legal certainty, consumer trust, and ethical competitiveness.

The Chinese company is adapting to the demise of Moore's Law, which guides chip production. It could complicate US chip dominance. Tingbo He, president of Huawei's chip-design subsidiary HiSilicon, says her company's engineers have developed a novel way to optimize semiconductors--and she believes it will close the performance gap between Chinese and Western chips over the next few years. Huawei's method, in short, focuses on speeding up computations across chips, circuits, and entire computing systems, rather than squeezing ever-more components onto a single piece of silicon. "We found a new path," He said at the IEEE International Symposium on Circuits and Systems in Shanghai last weekend.

Today, TIME convenes the first-ever TIME100 AI Leadership Forum in New York City, featuring a series of conversations exploring how artificial intelligence is shaping the future of our world across business, policy, ethics, society--and beyond. "We are proud to convene the inaugural TIME100 AI Leadership Forum, bringing together influential leaders from the TIME and TIME100 AI communities at a pivotal moment for artificial intelligence. These conversations are essential to ensuring innovation is guided by responsibility, insight, and purpose, and we are grateful to our partners, Amazon One Medical and Publicis Sapient, for supporting this important convening," said TIME CEO Jessica Sibley "At TIME, our mission is to spotlight the people and ideas shaping the future. The TIME100 AI Leadership Forum brings that mission to life by convening leaders at the center of AI and the shifting landscapes across industries, while exploring the opportunities, challenges, and responsibilities that will define the next era of innovation," said TIME Executive Editor and Chief Strategy Officer Dan Macsai The TIME100 AI Leadership Forum is the newest extension of TIME's growing Leadership Forum series, which brings together the world's most influential leaders for dynamic conversations around the ideas and innovations shaping our future. Following the TIME100 Health, Climate, and Women of the Year Leadership Forums, the inaugural AI forum builds on TIME's expansive coverage of artificial intelligence and its annual TIME100 AI list, which recognizes the 100 most influential people shaping the future of AI.

On May 22, 2026, the Pentagon released a second batch of previously classified photos and videos showing what appear to be unexplained flying objects. These file dumps were the culmination of a process that was set in motion back in July 2023, when a group of government whistleblowers testified before Congress that the U.S. government was secretly in possession of extraterrestrial spacecraft and suspected alien body parts.

Table tennis robot defeats some of world's best players - why this has major implications for robotics A table tennis robot has outperformed elite players in recent evaluations. The robot, called Ace, marks a significant step toward artificial intelligence (AI) systems that can operate in fast, uncertain, real-world environments. In the tests, the autonomous robot won three out of five matches against elite players - competitive athletes with over ten years' experience and an average of 20 hours weekly training. The robot, developed by Sony AI, lost both matches against players in professional Japanese leagues, but did win a game against one of them. The system is described in detail in a recent paper published in Nature .

The rise of AI tools that instantly answer questions and complex problems could make humans less intelligent, the Royal Observatory Greenwich has warned. The Observatory, one of the UK's oldest purpose-built scientific institutions, is known for its contributions to astronomy. Paddy Rodgers, director of the Royal Museums Greenwich group which oversees it, said its rich history of research showed the power of human knowledge and curiosity - and the need to avoid complete dependence on AI. A reliance solely on instant answers risks losing the habits of questioning and evaluation that underpin knowledge, expertise and innovation, he said. Rodgers' remarks come amid an ongoing transformation of the Royal Observatory in a project called First Light. The project hopes to seize on the passion of all the astronomers over the last 350 years, and interpret that passion through science, Rodgers told the BBC.
