Analysis of a spermiogenesis protein reveals a new chromatin requirement for synchrony between maternal DNA packaged in the egg and sperm-packaged paternal DNA in the first embryonic mitosis in Drosophila melanogaster.

Morphologic, molecular, biomechanical and computational analyses show that the specialized extracellular matrix architecture of the umbilical artery contributes to its rapid closure at birth and regulates smooth muscle cell differentiation.

The dual function of an ancient prokaryotic enzyme, which is linked to specific metabolite signals, may have been the evolutionary driving force behind its dual localization in eukaryotes.

Epigenetic reprogramming by LSD1/KDM1A acts at fertilization in mice to enable embryogenesis and prevent behavioural abnormalities.

Guidelines governing research into embryos need to be updated in a way that reflects the moral status of synthetic human entities generated using the methods of synthetic biology.

Tick-derived sequence variation in the fusion glycoprotein of Crimean-Congo hemorrhagic fever virus (CCHFV) drastically impairs infection of mammalian cells, suggesting that certain CCHFV strains undergo purifying selection in mammalian hosts.

Generation of a home-and-rescue gene drive targeting an essential gene reveals confinable population modification.

The ATP7A interactome is the first comprehensive view of putative Menkes disease neurodegeneration mechanisms.

Reproductive fluids help the correct establishment of some epigenetic marks and gene expression in preimplantation pig embryos.

Recent reports on the ability of biological molecules to sense magnetic fields are found to be inconsistent with basic physical principles.
