‘Universal vaccine’ protects mice against multiple pathogens An innovative approach supercharges the innate immune system to provide a first line of defence against respiratory infections.

Imagine if a nasal spray could make you immune not only to the viruses that cause COVID-19 and influenza, but to all respiratory diseases

From Earth to space - exploring fungi in extraterrestrial environments Fungi are incredible organisms in terms of plasticity, resilience, and adaptation. However, they have the potential to both help and hinder us.

With renewed momentum in space exploration, we revisit a feature that took us from Earth to space, exploring the surprising role fungi could play 🌌 https://www.the-microbiologist.com/features/from-earth-to-space-exploring-fungi-in-extraterrestrial-environments/5071.article

Genetic compatibility and ecological connectivity drive the dissemination of antibiotic resistance genes - Nature Communications The dynamics of antimicrobial resistance gene transfer remain unclear. Here, by integrating bacterial genome and metagenome data with machine learning the authors show that genetic incompatibility is a main limiting factor, while co-occurrence of bacteria in the human microbiome and wastewater contributes to gene transfer.
