The gene moeA is involved structural colour of some bacterial colonies by modifying cell shape and colony organisation, thus causing a shift in reflected colour.
T cells must encounter pathogen-derived antigens directly in the skin to differentiate into optimally effective, long-lived tissue-resident memory T cells.
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.
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.
