T cells must encounter pathogen-derived antigens directly in the skin to differentiate into optimally effective, long-lived tissue-resident memory T cells.

Brain gels and computational modelling provide insights into the mechanisms underlying brain folding during development.

Differences in brain folding between species can be explained by variations in initial brain size, shape and cortical growth rate, rather than by different folding mechanisms.

Reviewer citation requests can turn peer review into a transaction rather than an objective critique of the article.

Studying the evolution of all aspects of shark teeth may reveal important insights into how different groups of sharks may adapt differently to changing environments.

A new computer algorithm allows the recording of the same developing neurons over time.

GPS loggers facilitate the location tracking of individuals residing in high-risk leptospirosis areas, enabling a more accurate assessment of infection risk associated with this bacterial disease, which is prevalent in marginalized urban communities.

The pattern of cell death in the cerebellum differs between disease and normal aging.
