The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how ...

Feathers, essential for thermoregulation, flight, and communication in birds, originate from simple appendages known as proto-feathers, which were present in certain dinosaurs.By studying embryonic ...

Scientists uncovered a key genetic pathway in the origin of feathers, but they found that evolution is stubborn in turning ...

During embryonic development, the intestine of the Drosophila fly divides into distinct chambers thanks to the formation of ...

While a transient over-expression of the gene can permanently turn feet scales into feathers, it is much harder to disrupt ...

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 ...

Human biology is not black and white. Although newborns are typically categorized as male or female at birth based on visible ...

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 ...

In a study of early embryonic development in primates, an international research team under the leadership of Berthold ...

A study reveals how the Wingless signalling pathway shapes the embryonic intestine of the Drosophila fly, activating a mechanism involved in calcium transport. The finding redefines the role of ...

Inhibiting the sonic hedgehog (Shh) pathway strongly perturbs feather development in chickens by restricting feather bud outgrowth, invagination and ...
