Chickens treated to inhibit the sonic hedgehog (Shh) pathway during development grow feathers that resemble ancient ...

In a nutshell Scientists temporarily reversed feather evolution in chickens by blocking a key developmental pathway, causing ...

Scientists have successfully genetically modified chickens to make their feathers resemble those of dinosaurs. This study is ...

Feathers may have started as simple filaments in ancient dinosaurs, but a team of Swiss researchers is digging deep into the ...

Recreating the first dinosaur proto-feathers ‘‘Since the Shh pathway plays a crucial role in feather development, we wanted to observe what happens when it is inhibited,’’ explains Rory ...

An international research team has identified a new dinosaur species in Argentina, an apex predator so ferocious that it was named after an evil spirit from a local myth. Maip macrothorax ...

Over the last two decades, dozens of fossilized dinosaur remains bearing evidence of feathers or quill-like protofeathers have surfaced, most notably among ornithischians and coelurosaurian theropods.

From two weeks onwards, feather development in the embryos partially returned to normal. The chicks with the altered pathway ...

A recently discovered dinosaur’s claws are making waves. Researchers have unearthed a feathered, two-legged dinosaur with huge claws named Duonychus tsogtbaatari. The fossil is around 90 to 95 ...

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 ...

At the 12th day of incubation, feather buds exhibit longitudinal domains of cell density that correspond to the barbs of the future down feather.
