Scientists engineer bacteria-killing molecules from wasp venom

A team led by scientists in the Perelman School of Medicine at the University of Pennsylvania has engineered powerful new antimicrobial molecules from toxic proteins found in wasp venom. The team hopes to develop the molecules ...

Moth gut bacterium defends its host by making antibiotic

Nearly half of all insects are herbivores, but their diets do not consist of only plant material. It is not uncommon for potentially harmful microorganisms to slip in during a feast. In a study published on January 19 in ...

Mouse genetics influences the microbiome more than environment

Genetics has a greater impact on the microbiome than maternal birth environment, at least in mice, according to a study published this week in Applied and Environmental Microbiology. Vaginal birth, known to transfer microbiota ...

A new weapon in the fight against superbugs

The ever-increasing threat from "superbugs"—strains of pathogenic bacteria that are impervious to the antibiotics that subdued their predecessor generations—has forced the medical community to look for bactericidal weapons ...
