The gas orbiting Sagittarius A (Sgr A*), the supermassive black hole at the center of the Milky Way galaxy, is rich in metals, researchers at McGill University's Trottier Space Institute have found. The metal enrichment probably ...
The positron is the antimatter counterpart of the electron, identical in mass but carrying an equal and opposite electric charge. Like the electron, it also behaves like a tiny bar magnet, and according to a key prediction ...
The Orionids—one of two major meteor showers caused by remnants from Halley's Comet—will peak this week, though a large moon will dim visibility until after it sets late at night.
Common ways of reporting perfluoroalkyl and polyfluoroalkyl substances (PFAS)—the man-made, so-called forever chemicals that pose environmental and health threats—could underestimate the concentration of PFAS in U.S. drinking ...
Drone-mounted laser technology is helping archaeologists locate Aboriginal rock art sites hidden in the rugged, densely vegetated landscapes of Australia's Blue Mountains, demonstrating a new approach to surveying archaeological ...
The interstellar comet 3I/ATLAS brought material from another planetary system within reach of our telescopes, but reading its chemistry poses a problem. Energetic particles encountered during its journey through space may ...
Populations of many pollinators, including bumblebees, have been crashing over the last few decades, thanks to the widespread use of chemical pesticides, loss of habitat and the acceleration of climate change. But it can ...
An international study led by the Institute of Evolutionary Biology (IBE, CSIC-UPF) in Barcelona, the Natural Sciences Museum of Barcelona, Harvard University and the University of the Basque Country (EHU) has reconstructed ...
The Kronshtadskiy subglacial lake near East Antarctica's Amery Ice Shelf was hidden beneath Antarctica's ice, but its drainage left a mark visible from space as a broad depression that deepened by more than 6 meters (20 feet) ...
In a discovery that could offer a new way to control quantum properties in two-dimensional materials, researchers at Cornell have found that electrically sliding the layers of ultrathin graphene can switch the material between ...
