“Reduced telomere length can be caused by embryonic cellular damage,” said study co-lead Dr. Yasmyn Winstanley. The ...

Scientists have found a way to study early embryonic development without real embryos. Using CRISPR, they programmed stem cells to self-organize into structures mimicking early embryos. The cells show ...

A growing body of work suggests that cell metabolism — the chemical reactions that provide energy and building materials — ...

Scientists recreate ancient proto-feathers in chicken embryos, revealing evolutionary resilience in feather development.

Human embryos briefly exhibit traits like tails and gill-like structures, revealing our evolutionary history and deep ...

Feathers may define birds today, but their story began millions of years ago in creatures that looked very different from ...

Feathers are complex skin structures, and their evolutionary beginnings are still a subject of scientific debate. Scientific ...

In a breakthrough at the intersection of quantum physics and biology, researchers at the University of Adelaide have figured ...

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 ...

Oxytocin, a hormone linked to bonding behaviors, might also help mice modulate their pregnancies. Someday, this line of ...
