New research from the University of the Witwatersrand in Johannesburg, South Africa (Wits University), has shown that heavy metals such as lead, arsenic, cadmium and mercury accumulate in the scales of Black Mambas (Dendroaspis polylepis).

The study, conducted on snakes captured in Durban in KwaZulu-Natal and published in Environmental Pollution, was the first of its kind to examine heavy metal accumulation in an African snake species. The results mean that researchers can use scale clippings from these snakes to accurately measure spatial patterns of environmental pollution levels, without harming the snakes. 

Professor Ogawa, Mr. Echigo (PhD student), and their colleagues in Kanazawa University report in Eur J Nucl Med Mol Imaging that combination of an At-211-labeled agent with immune checkpoint blockade significantly enhances its therapeutic effect. This strategy represents a promising advancement in the development of next-generation cancer therapies that combine targeted alpha therapy and immunotherapy.

Green hydrogen holds immense promise for decarbonizing energy systems, yet when produced via water electrolysis, it relies heavily on rare and expensive noble metals. This study delves into the emergence of non-noble metal catalysts (NNMCs) as a transformative alternative for the oxygen evolution reaction (OER) in acidic environments. By unpacking the underlying mechanisms, performance bottlenecks, and degradation routes, the authors offer a roadmap to designing high-performing, stable NNMCs. The review also explores the latest innovations in catalyst engineering—from electronic tuning to surface reconstruction—that enable these cost-effective materials to rival their noble metal counterparts in water-splitting performance.

Innovation Center of NanoMedicine (iCONM), in collaboration with Prof. Takahiro Nomoto's Lab at the University of Tokyo, will hold a seminar on drug design and rationalization of treatment protocols for photodynamic therapy (PDT) based on singlet oxygen imaging on September 19, at 1:30 pm. This is based on a Japan-Germany Bilateral Collaboration Research between DAAD (German Academic Exchange Service) and JSPS (Japan Society for the Promotion of Science), with the aim of expanding the framework for joint research on the topic PDT and stimulating its international collaboration.
