Rising temperatures will lead to a massive “greening” of the Arctic by mid-century as a result of striking increases in plant cover, according to new research led by the American Museum of Natural History.
Like the 18th-century German naturalist August Johann Rösel von Rosenhof, whose beautifully illustrated Historia naturalis ranarum nostratium (Natural history of the native frogs) he describes in an essay in Natural Histories, Curator Darrel R. Frost has created a comprehensive reference about amphibians. He manages Amphibian Species of the World, an online database and classification system for about 7,000 amphibian species, of which about 6,200 are frogs.
Astronomers have conducted a remote reconnaissance of a distant solar system with a new telescope imaging system that sifts through the blinding light of stars. Using a suite of high-tech instrumentation and software called Project 1640, the scientists collected the first chemical fingerprints, or spectra, of this system’s four red exoplanets, which orbit a star 128 light years away from Earth.
