Portal hypertension is a serious complication of chronic liver disease that can lead to life-threatening conditions such as internal bleeding and liver failure. A new study examines how advances in imaging, blood-based biomarkers, predictive models, and artificial intelligence are reshaping the non-invasive diagnosis of the condition. By bringing together the latest evidence, the review highlights how these approaches could support earlier detection, improve disease monitoring, and reduce the need for invasive procedures.

Certain systems exhibit collective dynamics driven by nonreciprocal interactions, where particles do not exert equal influences on one another. Researchers from Tokyo University of Science demonstrated such behavior in a colloidal system containing more than 10,000 particles. Instead of growing into large static aggregates, the particles formed self-propelled pairs that sustained a dynamic, fragmented state. The experiment provides a platform for studying nonreciprocal interactions and their role in shaping collective dynamics in large-scale systems.

Seoul National University’s College of Engineering announced that Hyunsoo Lee, an undergraduate student in the Department of Electrical and Computer Engineering, has presented research in generative visual computing, spanning image editing and 3D content generation, at leading international conferences in machine learning and computer vision, including NeurIPS, CVPR, and ECCV. These conferences represent premier venues in their respective fields, making Lee’s sustained record of publication as an undergraduate particularly noteworthy.

It has been discovered for the first time that the same silver (Ag) nanocatalyst operates at different reaction sites depending on whether the solid oxide cell is generating electricity or producing hydrogen. This finding introduces a new design principle for improving the performance of next-generation solid oxide cells.
