The new whale shark genome assembly represents the best gapless chondrichthyan genome assembly yet, and comparative genomic analyses provide insights into the evolution of vertebrate genome origins, immunity, and gigantism.
Early oocyte development takes place in germline cysts and is strikingly conserved from Drosophila to mouse, reflecting common mechanisms that may help reverse aging and specify oocyte and early embryo polarity.

A mechanistic basis is provided for the regulative ability of the mammalian embryo offering a long-sought explanation for coordinating cell behaviors at the population level ensuring robustness in developmental outcome.
Genetic analyses reveal the importance of dynamic protein processing at the apical cell membrane in response to forces damaging cell membranes during tube expansion in tubular organs.
Analysis of mouse zygotic genome activation (ZGA) reveals that a mis-annotated multicopy homeobox gene Obox4 functions redundantly with Dux to promote ZGA.
