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 ea
Isolating specific cell types from a mass of plant or animal tissue is laborious and tricky. To study epigenetic changes and genes that are expressed differently in different cell lineages—such as cancer cells versus normal cells, or the two types of
Using synchrotron rapid scanning X-ray fluorescence to map the distribution of trace metals in avian fossils over 120 million-year-old, researchers reconstruct the pigment patterns of their feathers—revealing some of the extinct birds' long-lost colo
