Two Novel S‐methyltransferases Confer Dimethylsulfide Production in Actinomycetota
Advanced Science, EarlyView.This study identifies two novel S‐adenosine‐methionine‐dependent methyltransferases, MddM1 and MddM2, in actinomycetes from the Mariana Trench. These enzymes can convert toxic hydrogen sulfide (H2S) and methanethiol (MeSH) into dimethylsulfide (DMS), serving as a cellular detoxification and oxidative stress response.

Contribution of the antibiotic chloramphenicol and its analogues as precursors of dichloroacetamide and other disinfection byproducts in drinking water [PDF]
, 2015 Dichloroacetamide (DCAcAm), a disinfection byproduct, has been detected in drinking water. Previous research showed that amino acids may be DCAcAm precursors. However, other precursors may be present.

A Modular Vaccine Platform Against SARS‐CoV‐2 Based on Self‐Assembled Protein Nanoparticles
Advanced Science, EarlyView.A modular BP26 nanoparticle vaccine platform incorporating the SpyTag/SpyCatcher system enables high‐density, repetitive antigen display with post‐expression flexibility. Conjugation of the SARS‐CoV‐2 RBD to BP26 nanoparticles elicits strong humoral immunity and confers protection against viral challenge in vivo.

Advanced Science, EarlyView.To distinguish how Salmonella invades cells vs how it survives long‐term, a parallel CRISPR screening platform is developed. This approach reveals the host proteins that the bacterium exploits at different stages of infection. The study identifies SORL1 as a novel host factor for invasion and demonstrates that blocking it with an antibody effectively ...
