By combining experimental data with computer models, researchers were able to predict a pathogen’s evolution toward more virulence.

The antimicrobial drug neomycin protects mice from some viral infections, complicating the picture of the relationship between antibiotics and susceptibility to viruses.

The drugs’ disruption of the microbiome makes a subsequent flavivirus infection more severe.

A study finds that the vaccine’s effects wear off as a person ages, suggesting a need for booster shots.

The findings more than double the number of known defense mechanisms, piquing the interests of molecular biology tool developers.

Research shows that human immunity develops much earlier than previously thought, but functions differently in adults.

Constant exposure to the sounds of a busy road can impact a male European tree frog’s stress levels, immune system, and vocal sac coloration, scientists show.

Vaccine-induced macrophages open a new realm of study into remodeling the immune system to reduce the risk of infections during cancer treatment.

The latest CRISPR deactivators to be discovered turn off the Streptococcus pyogenes Cas9 widely used in genome editing.

A metagenomics analysis finds Cas9 in archaea for the first time, along with two previously unknown Cas nucleases from bacteria.
