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 ...

A study by researchers at Columbia University Vagelos College of Physicians and Surgeons has found that new cutting-edge ...

The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

Learn how a slower-growing gut helps snake embryos curl into a spiral, allowing their long bodies to develop inside an egg.

For several years, researchers studied human embryonic stem cells (ESCs) to understand the unique features of these pluripotent cells, but on their own, they poorly resembled the complex structures ...

A popular vanilla flavoring in e-cigarettes may interfere with some of the earliest steps of human development. In lab experiments, vanillin caused embryonic stem cells to lose their ability to ...

Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

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 ...

Can a snake be left-handed or right-handed? We’re not talking in the same way you or I would favor a hand, of course. But ...

The Gazette offers audio versions of articles using Instaread. Some words may be mispronounced. Every time I see a letter denouncing evolution, I think back to my sixth-grade science class where the ...
