The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

What do the earliest stages of a pregnancy look like? Embryonic development has been extensively studied, but most of our knowledge of the earliest stages of a growing baby come from stationary ...

Magdalena (Magda) Zernicka-Goetz, today a developmental and stem cell biologist at the University of Cambridge and California Institute of Technology, recalled being an artistic child who enjoyed ...

Over the past year or two, we have been exploring what we termed the origins—or the embryology—of human development. We examined the three pillars of development: Feelings (Affects), Language, and ...

Using CRISPR-based engineering methods to prompt stem cells to organize into embryo-like structures, scientists were able to create 'programmable' cellular models of embryos without ever experimenting ...

A lot happens in the first month of human embryo development as a single cell morphs into multitudes. Yet despite its significance, this period is basically a “black box” to researchers, says stem ...

A team of scientists has just gotten a closer peek into one of the earliest and most fundamental steps of creating a human life. Research out today highlights how they captured—for the first ...
