New research is underway to decipher a fascinating biological puzzle—how some animals can naturally discard more than half of their genetic information during embryonic development. This radical ...

At least 8% of the human genome is genetic material from viruses. It was considered ‘junk DNA’ until recently, but its role in human development is now known to be essential Researchers at the Spanish ...

In the earliest hours after fertilization, an embryo takes its first steps toward becoming a living organism by shedding maternal control and activating its own genetic program. This critical process, ...

Researchers at the University of Connecticut have reported a novel bovine embryonic stem cell line with improved pluripotency and broader translational potential. The platform has opened routes ...

Scientists have uncovered a surprising new way that giant embryonic cells divide—without relying on the classic “purse-string” ring long thought essential for splitting a cell in two. Studying ...
