Zebrafish midline tissues coordinate their growth during embryonic development using a leader-follower strategy described by formation control, as reported by researchers from Japan and the USA. The notochord leads elongation, while adjacent tissues grow and migrate with it in response to fibroblast growth factor gradients, cadherin-2-mediated cell adhesion, and mechanosensory Yap signaling. The researchers could replicate this behavior using a mathematical model, revealing a control theory-based principle for harmonized tissue development in embryos.
Choosing how to live in a way that truly helps our overburdened planet can be difficult. Researchers at DTU have calculated the impact of a wide range of everyday activities to help consumers lighten their impact on the environment.
Researchers have shown for the first time how hidden motions could control how granular materials such as soil and snow slip and slide, confirming a long-suspected hypothesis. The knowledge could help in understanding how landslides and avalanches work and even help the construction industry in the future.
Shanghai, August 21, 2025 — Nuclear energy is widely recognized as one of the most promising clean energy sources for the future, but its safe and efficient use depends critically on the development of robust nuclear fuels and structural materials that can endure extreme environments. A newly published review in AI & Materials highlights how machine learning (ML) is transforming this field, enabling scientists to accelerate discoveries, optimize performance, and overcome long-standing challenges in nuclear materials research.
The article, titled “Machine learning in research and development of advanced nuclear materials: a systematic review for continuum-scale modelling,” was authored by Chaoyue Jin and Professor Shurong Ding from the Institute of Mechanics and Computational Engineering at Fudan University. It provides an in-depth systematic review of how ML has been applied to nuclear fuels and structural materials, particularly at the continuum scale.
AI chatbots have been blamed for motivating suicidal behavior in several cases, raising concerns the popular tools could dispense harmful advice to those experiencing mental health emergencies. A new study finds that three widely used artificial intelligence chatbots generally do a good job responding to very-high-risk and very-low-risk questions about suicide, but they are inconsistent in answering questions about suicide that may pose intermediate risks.
