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 ...

Birds show an amazing diversity in plumage color and patterning. But what are the genetic mechanisms creating such patterns? Researchers now report that two independent mutations are required to ...

Estrogen derived from the ovaries transforms the default (primitive) male-type feathers into female-type feathers by regulating the hormone systems within the feather follicles. Birds possess unique ...

Scientists have successfully genetically modified chickens to make their feathers resemble those of dinosaurs. This study is part of a broader effort to understand how and why feathers evolved.

ONLY very recently was I able to read Nickerson's paper1 on barred pattern formation in chicken feathers. Nickerson's experimental analysis by means of melanophore transplantation according to H. B.

A regular-sized chicken has at least 10,000 feathers. With Americans eating 8 billion chickens annually, the feather supply is endless. Unlike geese, chickens don’t produce the type of down needed to ...
