Manure digesters, touted as eco-friendly solutions for managing agricultural waste and reducing greenhouse gases, have limited capacity to reduce livestock-related greenhouse gas emissions, and entail potential hazards that may outweigh their benefits, according to a new paper from researchers at the Johns Hopkins Bloomberg School of Public Health.

A team led by Prof. SHAO Zhigang and Prof. ZHAO Yun from the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences enhanced the durability of pure water-fed anion exchange membrane electrolysis, which achieves over 2,400 hours of stable operation through membrane-electrode interface engineering.

IT-Security Researchers from the University of Vienna and SBA Research identified and responsibly disclosed a large-scale privacy weakness in WhatsApp's contact discovery mechanism that allowed the enumeration of 3.5 billion accounts. In collaboration with the researchers, Meta has since addressed and mitigated the issue. The study underscores the importance of continuous, independent security research on widely used communication platforms and highlights the risks associated with the centralization of instant messaging services. The preprint of the study has now been published, and the results will be presented in 2026 at the Network and Distributed System Security (NDSS) Symposium.
