Distant exploding stars observed by NASA’s Hubble Space Telescope are providing astronomers with a powerful tool to check the "prescription" of supernovae that act as natural “cosmic lenses.” Astronomers use these lenses to capture a magnified view of the remote universe.
New study, led by scientists at the American Museum of Natural History, shows that living sharks are actually quite advanced in evolutionary terms, despite having retained their basic “sharkiness” over millions of years.
Living harvestmen—a group of arachnids commonly known as daddy longlegs—have a single pair of eyes. But a newly described 305-million-year-old fossil found in eastern France shows that wasn’t always the case.
New research on the skulls of red pandas and giant pandas provides further explanation as to why the two species—which are not closely related but dine on the same food, bamboo, in the same geographic area—are able to coexist.
