As a recent leap in green chemistry, scientists from Japan have unveiled a new catalyst that enables high yields of sulfones using molecular oxygen—close to room temperature. By fine-tuning the structure of oxygen vacancies in perovskite oxide catalysts, the researchers successfully reduced the reaction temperature from 80–150°C to nearly 30°C, offering improved energy efficiency. The study marks a significant milestone in advancing complex sulfide oxidation reactions, offering sustainability with excellent efficiency.

MicroRNA-27a has been shown to stimulate both the wingless-type integration site family, or Wnt signaling, and the bone morphogenetic protein pathways to actively promote bone regeneration, according to a recent study from Institute of Science Tokyo, Japan. Their important findings shed light on the intrinsic cellular pathways and mechanisms that are critical for the development of new bone-like tissue and could inform the design and development of future tissue regeneration therapies.

The recent global monkeypox (mpox) outbreak, with a new and aggressive variant, has underscored the dire need for safe, broadly effective, and accessible vaccines. The LC16m8 vaccine, an attenuated vaccinia virus strain originally developed for smallpox, is a promising option for countering the mpox virus. Exploring this potential further, researchers employed a cross-species immunological analysis to provide new insights into LC16m8’s immunogenicity and safety against mpox.
