The frequency of SIV reactivation from latency after treatment interruption is not directly related to measures of SIV DNA, RNA, immune activation or immune response in peripheral blood.

Following exposure of Leishmania culture promastigotes to DNA stress, single-cell RNA sequencing reveals discrete clusters of cells associated with efficient generation of hybrids between different species and strains in vitro marked by expression of the ancestral gamete fusogen HAP2.

A common chromosome inversion in African malaria mosquito (Anopheles gambiae) is associated with differences in malaria infection, adult resting behavior and ecology, and may aid the most efficient vectors to evade malaria control.

A kinetic model of morphogen interpretation is more suitable than classic threshold or ratchet models to understand how a signal gradient generates different target gene expression patterns.

Whole-genome sequencing reveals the remarkable extent of horizontally moving genetic material in naturally competent Vibrio cholerae after a prey-killing DNA acquisition process.

Sequence changes in the pneumococcal genome explain most of the variability in duration of asymptomatic carriage with serotype, antibiotic resistance and prophage accounting for the largest effects.

A high-throughput microscopy screen for drugs that modulate SARS-CoV-2 spike-mediated membrane fusion identifies an essential role for cholesterol in both virus entry and syncytia formation.

Genetic, structural, and biochemical analyses of IS607-family transposons shows that the DNA translocation reaction proceeds very differently from other reactions promoted by serine recombinases.

Tapeworms grow and regenerate using stem cells distributed throughout their bodies, but their regeneration competence relies upon the unique micro-environment created by the head and neck.

Ligand capture by cell surface receptor complexes sets the shape of the Nodal signaling pattern in zebrafish.
