Astronomers Spot Giant X-Ray Rings around Stellar-Mass Black Hole

Astronomers using NASA’s Chandra X-ray Observatory and Neil Gehrels Swift Observatory have detected a set of eight X-ray rings around a low-mass black hole in V404 Cygni, a binary system located about 7,800 light-years away in the constellation of Cygnus. These rings are created by light echoes, a phenomenon similar to echoes on Earth from sound waves bouncing off hard surfaces. V404 Cygni is a...

Scientists Use DNA Barcoding to Identify Tool Materials of New Caledonian Crows

Using a taxonomic method called DNA barcoding, researchers have identified, from just a few recovered tool specimens, the plant species New Caledonian crows (Corvus moneduloides) use for crafting their elaborate hooked stick tools. New Caledonian crows — a species of oscine passerine bird found on the South Pacific island of New Caledonia — are renowned for their ability to manufacture complex ...
