Biodegradable pigments could be custom-grown by bacteria in the future, say researchers.  

A new study reveals that a constant stream of ink-gobbling immune cells helps hold tattoos in place.

Zebrafish, Danio rerio, develop patterns of colorful stripes on their skin thanks to pigmented cells—dark melanophores, orange-gold xanthophores, and iridescent iridophores. 

Immune cells called macrophages shuttle cellular messages in the skin.

People without red hair who possess the variant are also more likely to develop this form of skin cancer, researchers report.

Analysis of a 7,000-year-old human genome suggests that Mesolithic people had relatively dark skin and had begun to evolve pathogen resistance characteristic of modern Europeans. 

Researchers seek insight into the pigmentation patterns of guppies and zebrafish.

Scientists engineer a spectrum of artificial pigments to understand how animals see in color.

Dinosaur and early bird feathers trapped in amber around 80 million years ago provide unprecedented insight into the evolution of plumage.

After rummaging through thousands of amber inclusions housed at the University of Alberta and the Royal Tyrrell Museum of Paleontology in Canada, researchers discovered 11 amber encased-feather fossils that provide the most detailed picture yet of early feather evolution.
