New research revising rules on deciphering color in dinosaurs may provide a tool for understanding the evolutionary emergence of flight and changes in dinosaur physiology. While surveying melanosome ...

Many paleontologists believe that the shape of fossilized pigment containers in cells can help determine dinosaur colors. But some remain skeptical.

Melanosome shape varies in the different samples, and is indicative of color. The sample furthest to the left was predicted as iridescent view more Credit: Photographs of Scaniacypselus and ...

The study of fossil feathers and melanosome preservation has significantly advanced our understanding of the evolutionary history of vertebrate integumentary systems. Fossilised feathers, replete with ...

Manipulating the functions of melanosomes -- the organelles in pigment-producing cells -- may enhance the activity of anticancer drugs used against melanoma, according to a new study. Manipulating the ...

The role of clathrin adaptor proteins in sorting cargo in the biosynthetic and recycling routes is an area of intense research. In this issue,Delevoye et al. (2009. J ...

New research that revises the rules allowing scientists to decipher color in dinosaurs may also provide a tool for understanding the evolutionary emergence of flight and changes in dinosaur physiology ...
