Humans are having a highly detrimental impact on biodiversity worldwide. Not only is the number of species declining, but the composition of species communities is also changing. These are the findings of a study by Eawag and the University of Zurich published in the scientific journal Nature. It is one of the largest studies ever conducted on this topic.

A team of researchers from Beihang University and Truth Memory Corporation has fabricated a 1 Kbit spin-orbit torque magnetic random access memory (SOT-MRAM) chip with an implemented physical unclonable function (PUF). Published in Engineering, the new PUF shows high reliability, reconfigurability, and resistance to machine-learning attacks, offering a potential solution for Internet of Things (IoT) security issues.

Traditional teaching methods may not fully prepare students for the digital era. A recent discussion explores how AI-driven strategies can enhance learning outcomes and engagement. It examines adaptive learning platforms, intelligent tutoring systems, and AI-assisted assessments, highlighting their role in personalizing instruction and improving student performance. By integrating these technologies, educators can reshape modern classrooms. This discussion provides insights into the transformative potential of AI in education.

A study published in Engineering provides a comprehensive review of actuation and locomotion methods for miniature underwater robots (MURs). Titled "Actuation and Locomotion of Miniature Underwater Robots: A Survey," the research summarizes key propulsion technologies, evaluates their advantages and challenges, and explores future trends in MUR development for underwater exploration and marine applications.

The National Institute of Standards and Technology (NIST) has selected FAU’s Hamming Quasi-Cyclic (HQC) algorithm for standardization in its Post-Quantum Cryptography project. HQC was chosen for its security, efficiency and practical implementation in secure key exchange, which protects digital communications and ensures safe encryption against future quantum computing threats. FAU is the only U.S. university involved among all the authors of the two, winning key-encapsulation mechanism schemes selected by NIST, highlighting its prominent role in the field of post-quantum cryptography.

Energy sector decarbonization is a key battleground in China’s march toward carbon neutrality, and understanding what it means and takes is crucial for its policy-making and sustainable implementation. Here we analyze the structural challenges and review the necessary supporting technologies and systems of energy sector decarbonization in China. This work could achieve a better understanding of technology development and deployment, and to make more thoughtful policy recommendations.
