The physiological demands of that long neck get support from a gene involved in strengthening bones and blood vessels, researchers find after inserting the sequence in mice.
Researchers are pulling from video games, sports broadcasting, meteorology, and even missile guidance technology to better investigate how insects have mastered flight.
An isotopic analysis of eggshell beads dating back more than 30,000 years indicates that they helped build networks that stretched for hundreds of kilometers.
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 colors.
