At the American Society for Cell Biology's 2006 conference, scientists will describe their latest research on patterning, on the molecular and systems level. The scientists looked at how feather ...

According to a new study, the precise patterning of bird feathers relies on signaling through ectodysplasin (EDA) and its receptor EDAR -- the same signaling pathway known to be crucial for the ...

A patterning system that has been shown to play a role in bird feather development is also apparent in the development of sharks' tooth-like skin, new theoretical and experimental evidence finds. This ...

Stem cells have the remarkable potential to develop into many different cell types in a well organized spatial pattern. How adult stem cells regenerate and pattern themselves are mostly unknown.

Patterns are everywhere in nature, from the colors of Jupiter to a zebrafish’s stripes. Patterns even show up across very different animals. Scientists have long known that mammals’ hairs and birds’ ...

Some feathered dinosaurs may have lost the ability to fly, revealing that the evolution of flight was far more complex than ...

You have full access to this article via your institution. Peacocks use their brilliant plume to woo peahens. The very same feathers render the male bird vulnerable to predators. How then did peacocks ...

In eastern China, fossils of dinosaurs called Anchiornis have been discovered with their feathers intact. These specimens, 160 million years old, offer a unique opportunity to study the anatomy ...

Feathers evolved in dinosaurs and are a key characteristic of birds today. They are arranged in a precise hexagonal pattern in a bird's skin, but it has been unclear how this happens. According to a ...
