Several mechanisms contribute to the increased transmissibility of this SARS-CoV-2 variant.

Genetic testing of people who died in Kyrgyzstan eight years before plague reached Europe reveals an ancient strain of the bacterium Yersinia pestis.

The work reveals that the pandemic flu was likely the direct predecessor of the seasonal H1N1 flu that circulated for decades.

Different variants of the virus behind the COVID-19 pandemic are swapping chunks of genetic material, but it’s not yet clear what implications that may have for public health.

Researchers identify deletions in the N-terminal domain of the spike protein that allow the coronavirus to avoid antibody neutralization and that may contribute to the emergence of new variants.

The primordial emotion is apt to run amok. But harnessing it can lead to responsible behavior and sound thinking.

The McGill University paleontologist, who died from COVID-19, was known for using multidisciplinary methods to explore the origins of amphibians, birds, and mammals.

More than 320,000 mammalian viruses lurk; evolution of echolocation in bats and dolphins; accumulation of mutations in drug-resistant tuberculosis; senior researchers reluctant to retire
