The Korea Research Institute of Standards and Science (KRISS, President Dr. Lee Ho Seong) has developed an ultra-sensitive immunoassay-based analytical platform that can detect and quantify trace amounts of “Small Excised Damaged DNA (sedDNA)” fragments generated during cellular DNA repair. This technology enables highly sensitive detection with quantification down to the level of several thousand molecules, measuring up to 22 times more DNA fragments than conventional methods. It provides a new analytical foundation for comparing DNA repair capacity between individuals and studying cellular responses to anticancer drugs and carcinogenic agents.

Seed-grown Cannabis sativa crops often vary in flowering time, yield, sex expression, and chemical profile, making large-scale production less predictable. 

Seoul National University College of Engineering announced that a research team led by Prof. Seung Hwan Ko of the Department of Mechanical Engineering has developed an artificial skin technology that enables robots to sense temperature and pressure simultaneously, similar to human skin.

This review examines how indigenous water-harvesting systems have helped dryland communities manage scarce water for centuries. It shows that many are now declining due to groundwater pumping, migration, climate change, policy shifts, weak maintenance, urbanization and natural disasters. The authors argue that revitalizing these systems can improve water access, agriculture, livestock production, groundwater recharge and flood control, while preserving traditional knowledge. Combined with appropriate modern technologies and supportive policies, these systems can strengthen water resilience in arid and semi-arid regions.

A research team led by Prof. WANG Hongzhi at the Hefei Institutes of Physical Science, Chinese Academy of Sciences, has found a novel role of prostaglandin E synthase 3 (PTGES3) in liver cancer, revealing how it drives both tumor growth and immune suppression.

With the increasing clinical use of anti-amyloid-β monoclonal antibodies in Alzheimer’s disease in China, some patients have completed or are approaching the predefined treatment period, leading to emerging clinical questions regarding post-treatment maintenance, discontinuation, monitoring, and retreatment. However, no consensus has yet been established on long-term management or sequential-like treatment strategies after anti-amyloid-β monoclonal antibody therapy. Based on current clinical evidence and the practical experience of Renji Cognitive Center, this article proposes an experience-based protocol for sequential-like management of anti-amyloid-β monoclonal antibody therapy. The protocol uses amyloid PET-derived Centiloid values as the core objective reference and recommends stratified management according to clinical clearance status and prior amyloid clearance rate. This protocol is intended to provide a clinical reference and requires further validation and optimization through real-world studies and long-term follow-up.

Scientists have discovered that the electroactive bacterium Geobacter sulfurreducens can extract electrons directly from stainless steel to power its metabolism. Surprisingly, this is accomplished without destroying the metal’s protective chromium-oxide passive film, revealing a new mechanism by which microbes can accelerate corrosion of materials widely used in infrastructure and industry.
