Antigenic drift in influenza’s major surface proteins, hemagglutinin and neuraminidase, contributes to variability in epidemic magnitude across seasons but is less influential than subtype interference in shaping annual outbreaks.
Sequential therapy with only β-lactam antibiotics achieves surprisingly high potency by exploiting both low rates of spontaneous resistance emergence and low rates of spontaneous cross-resistance among the drugs in sequence.

Heterochromatic sequences evolve rapidly, as do ZAD-ZNF genes-encoding proteins involved in heterochromatin functions, explaining why evolutionarily dynamic ZAD-ZNF genes are more likely to be essential in Drosophila.
The common ancestor of extant mammalian coronaviruses originated recently in a bat species and their diversification occurred via preferential host switches rather than through codiversification with mammals.
Human gut bacteria alter their metabolism in response to each other's presence, which causes their community dynamics to deviate from predictions that are based on mono-culture data.
Whole genome deep sequencing of many longitudinally sampled HIV-1 populations reveals that reversions towards ancestral HIV-1 genome sequences occur throughout the course of infection.
