Genetic bottlenecks are evolutionary events that reduce the effective size and diversity of natural populations, often limiting a population's ability to adapt to environmental change. Given the accelerating human impact on ecosystems worldwide, understanding how populations evolve after a genetic bottleneck is becoming increasingly important for species conservation. Ash deposits from the 2022 Hunga volcanic eruption in the S...

In enzymes, the active site is the location where substrates are chemically converted. If this site is deeply buried within the protein, substrates must pass not only through the body of the protein via a tunnel, but also flexible, site-decorating loops to access the active site. These elements can act as filters that influence on both substrate specificity and activity. Identifying and understanding how they exert such contro...
