Authors of a new review urge researchers to consider how the chromosomal sex of a cell affects experiments in research on neurodegeneration.

Stronger interferon production, greater T cell activation, and increased susceptibility to autoimmunity are just some of the ways that females seem to differ from males.

Males and females show differences in gene expression, cell activation, and antibody production in response to some viral infections, but whether these influence COVID-19 outcomes is still unclear.

The gene BCO2 enables male and female members of some bird species to display dramatically different color patterns.

In some finch species, the difference between colorful males and muted females comes down to one gene, BCO2, which encodes an enzyme that degrades carotenoids.

As male Drosophila grow old, selfish genetic elements that are abundant on the Y chromosome become more active, which appears to reduce longevity.

A study finds improvement in the proportion of scientific projects that include both sexes, but analyzing results by sex is not routine.

Emerging data as well as knowledge from the SARS and MERS coronavirus outbreaks yield some clues as to why SARS-CoV-2 affects some people worse than others.

The molecular processes that lead males to be more susceptible to the disease are only beginning to come to light.
