Two DNA-recording systems traced cellular family trees across mouse embryogenesis, offering new insight into how organs form and when developing cells commit to specific fates. The...
Before most women know they're pregnant, an embryo has already begun organizing itself into the structures that will shape a developing body. Scientists have few opportunities to s...

New work in Arabidopsis reveals that an embryo-derived PIPL7 peptide signals through the IKU2 receptor kinase to polarize MINI3 expression and direct endosperm cellularization duri...
Roughly one in ten Americans lives with a neurodevelopmental condition, yet for decades scientists have struggled to answer a deceptively simple question: where, when, and how do t...
Cephalopods, like the octopus, have specialized arms and suckers, but how these structures evolved from the simple bodies of their mollusk ancestors remains a mystery. Researchers...
