Humans do not have tails, but do we have “what it takes” for a tail? Hens don’t have teeth, but they have the genes for it. With atavism, it is as if our genomes serve as archives of our evolutionary ...

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 ...

“A central question has been: How do thousands of genes work together in an embryo, and how is their activity linked to the movement of cells?” says first author Yinan Wan. To answer this question, ...

For the first time, a stem cell model has produced a structure resembling an early human embryo with a yolk-sac-like ...

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 ...

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 ...

Researchers have discovered that the earliest days of embryo development have a measurable impact on a person's future health and aging. Researchers from the University of Adelaide have discovered ...

Some newly reported clumps of cells growing in lab dishes have been hailed as the closest things to human embryos that scientists have ever made in the lab. These entities are human embryo models — ...
