Weather data could help predict up to three days in advance when the number of out-of-hospital cardiac arrests is likely to rise above average, according to a nationwide study of more than 114,000 cases by researchers from Semmelweis University, the Budapest University of Technology and Economics, and the Hungarian National Ambulance Service. The study, published in Public Health, found that lower temperatures emerged as one of the most important weather-related risk factors examined. In the future, models based on weather forecasts could help people with cardiovascular disease and their families prepare for higher-risk periods, while also supporting ambulance services and hospitals in managing expected increases in demand. 

In the International Journal of Extreme Manufacturing, researchers have built a flexible and ultra-fast artificial synapse printed entirely from room-temperature liquid inks that dissolves on demand in six minutes. The work shows that high-performance and brain-inspired hardware does not require extreme vacuum chambers, rare metals, or permanent electronic waste.

Irrigating U.S. crops prevents higher greenhouse gas emissions by avoiding land conversion, groundbreaking new research by Colorado State University shows.

With the rapid development of 6G space–air–ground integrated communication networks, low Earth orbit (LEO) satellite constellations, leveraging their advantages of wide-area coverage and freedom from geographic constraints, have become key infrastructure for achieving global seamless connectivity. However, due to the relative motion among satellites in different orbits, inter-satellite links (ISLs) exhibit periodic dynamic on–off characteristics, among which a portion of the interruptions are predictable topological changes. Conventional Open Shortest Path First (OSPF) protocols compute shortest paths solely based on link distance, without considering link effective duration or bandwidth constraints, rendering them inadequate for adapting to the dynamic topological characteristics of satellite networks. Although fast reroute strategies can address sudden link failures, they consume substantial bandwidth resources and cannot provide protection for all nodes across the entire network. Therefore, how to proactively switch service paths before predictable link interruptions occur, so as to minimize service disruption and resource overhead, has become a core issue in ensuring service continuity in LEO satellite networks.

The U.S. National Science Foundation is investing $20 million in a two-year pilot led by UCF’s National Commercialization and Translation Institute to help NSF-funded small businesses overcome the “valley of death” and move late-stage deep technologies toward commercial success. The pilot will also evaluate approaches that could inform a scalable, long-term model.

A new Earth4All survey across 17 major economies finds strong public demand for economic change alongside sharply declining trust in governments to deliver it. Seven in ten respondents say inequality is excessive, 65% believe the economy is rigged for the rich and powerful, and 69% want major systemic change. Yet only 31% trust governments to make decisions benefiting most people over the long term, down from 39% in 2024. Two-thirds say their societies are increasingly divided. While 68% favour democracy, 40% would support a strong leader unconstrained by elections, highlighting risks when demands for reform go unmet.
