Antibiotic Resistance Through Bacterial Genes Inhibiting Viral Reproduction

Antibiotic resistance is a global health threat that could supplant cancer mortality within a few decades. Researchers at Umeå University, Sweden, found that the emergence of resistance can be explained by how bacteria develop defenses against virus infection.

Fluid Dynamics of Stentors Offers New Insight Into Evolution of Multicellular Life

Life emerged on Earth some 3.8 billion years ago. The "primordial soup theory" proposes that chemicals floating in pools of water, in the presence of sunlight and electrical discharge, spontaneously formed organic molecules.

Unveiling Bacterial Immune Mechanisms Against Temperate Phages

Like humans, bacteria can be attacked by viruses. In the case of bacteria, these viral attackers are referred to as bacteriophages, a term derived from the Greek word for bacteria-eaters, or simply “phages.”
