In triple-drug-treated HIV, partially resistant viruses can spread and resistance to specific drugs evolves in a predictable order, potentially a result of spatial or temporal heterogeneity in drug concentrations.

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.

Mapping mutations affecting gene expression within the yeast genome and within a gene regulatory network reveals properties of the raw material for regulatory variation.

The shared capacity of stem cells to recapitulate initial body plan formation in vitro without species-specific cues, suggests the existence of alternative, evolutionarily conserved developmental trajectories.

Outbreaks of SARS-CoV-2 transmission in a hospital environment show evidence of superspreading, with 80% of infections caused by 21% of infected individuals.

Neurogenic progenitor cells surrounding the eye placode generate neurons that migrate over long distances to the developing octopus brain.

The body plan of the 407-million-year-old plant fossil Asteroxylon mackiei comprised three developmentally distinct systems of axes.

The longer duration of seasonal influenza virus infection in young children may provide opportunities for within-host evolution as a result of maintenance of genetic diversity through mutation-selection balance.

Beliefs of others’ pain provide a cognitive basis of human empathy and altruism by modulating empathic brain activity.

Allele differences in gene expression dynamics are associated with insertions and deletions and are caused in part by multiple variants within the same promoter region.
