Researchers have finally revealed what gave the extinct Pink-headed Duck its unique-colored plumage.
Researchers recently discovered two-toned cats are born with distinctive black-and-white patches because certain pigment cells fail to multiply properly during early stages of embryo development. They suggest their findings could be used to to trace other genetic abnormalities, such as holes in the heart.
Harvard researchers created a mathematical model that helps explain how animals get their stripes and why they are oriented in certain patterns.
Most wild horses have lost their unique wild Dun coats that are characterized by pale hair and zebra-like dark stripes. In a recent study, researchers investigate the genetics behind this unique skin pigmentation and why horses have evolved differently.
Blue jays are adorned with striking blue feathers that never fade. It turns out birds are able avoid going gray – unlike humans – because their feathers contain sophisticated nanostructures that reflect light better than pigmentation.
Many species of blue tarantulas have evolved independently with the same coloration – a vibrant cobalt blue that is based in hairy nanostructures scientists believe could one day be replicated to improve smartphone and television screens.
Heavy metals such as mercury, chrome and copper alter the brightness of some birds' feathers, making them seem less attractive to females.
Orange lichens could be a potential source for anticancer drugs, Emory researchers revealed in a new study. A pigment known as parietin found in the lichens was tested on acute lymphoblastic leukemia cells and found to have significantly reduced or prevented cell growth within 48 hours.
A rare albino Risso's calf was recently spotted swimming with its mother in Monterey Bay, Calif.
Using fossilized structures known as melanosomes, researchers concluded that an ancient bat species was reddish-brown in color. More importantly, the study suggests that melanin desposits from fossils can be used to determine the color of ancient species.
Black rice, also known as forbidden rice, was once reserved for the Emperor. Now, it is widely popular for having high antioxidants. A new study sheds light on how the grains got their dark color.
Each fall like clockwork leaves start to change from green to various shades of yellow, orange and red. So why exactly do these colors surface in the fall?
Feathered fossils examined by Brown University researchers were found to hold vital pigment information about a bird-like dinosaur that died 150 million years ago.
An Antarctic octopus is giving new meaning to the phrase "blue blood," as a new study finds that the creature boasts unique blue pigments in its blood that allow it to survive ice-cold water, making it more resilient to climate change than other species.
