CT scans began to fill in the gaps, revealing a previously unidentified biological structure: an intestine located outside the embryo's body, but enveloped by blood vessels stretching from the yolk.

A MedUni Vienna study team led by geneticist Markus Hengstschläger has used a stem cell model to model the earliest stages of embryonic development and to characterize the membrane that surrounds the ...

Snake embryos develop in remarkably consistent clockwise spirals, and their slower-growing gut may explain how the unusual ...

Snake embryos begin life curled into a distinctive right-handed spiral, and scientists may finally know why. Their bodies grow faster than their guts, creating a tether that forces the lengthening ...

If you look at a nerve cell, a muscle cell, or a skin cell under the microscope, they appear strikingly different. However, every cell in our body has the same DNA and has descended from a common ...

A popular vanilla flavoring in e-cigarettes may interfere with some of the earliest steps of human development. In lab ...
