University of Cambridge scientists have used human stem cells to create three-dimensional embryo-like structures that replicate certain aspects of very early human development—including the production ...

For the first time in history, scientists have captured on film the moment a human embryo implants itself—an elusive biological milestone that has long been considered a “black box” in early human ...

The human genome is made up of 23 pairs of chromosomes, the biological blueprints that make humans … well, human. But it turns out that some of our DNA — about 8% — are the remnants of ancient viruses ...

Researchers at the University of Maine are theorizing that human beings may be in the midst of a major evolutionary shift—driven not by genes, but by culture. "Human evolution seems to be changing ...

A confocal microscopy image of a nine-day-old human embryo, with specific proteins and cellular structures colored distinctively. Green relates to embryonic stem cells and magenta associates with ...

Fossils unearthed in Ethiopia are reshaping our view of human evolution. Instead of a straight march from ape-like ancestors to modern humans, researchers now see a tangled, branching tree with ...
