Background selection is shown to be the dominant mode of linked selection in humans, with marked effects on diversity levels throughout autosomes.

Functional analyses of in vitro fertilized, preimplanation human embryos reveal that the first lineage segregation depends on cell polarization signaling that is regulated by Phospholipase C (PLC) activity.

Targeting the mothers, and other household members, of newborns with a mixture of respiratory syncytial virus (RSV) vaccines is both efficient and effective at reducing RSV hospitalizations.

Mice doubly deficient for Naa10 and Naa12 display embryonic lethality, with both enzymes compensating for each other with amino-terminal acetylation of proteins in mouse development.
