Astronomers have discovered the farthest-flung known stars in the Milky Way, objects whose presence suggests that our galaxy's 'halo' might be much larger than previously thought.
A study of chimpanzees' cognitive abilities suggest that some chimps are more intelligent than others, with genetic influences accounting for about half of the variability, say researchers.
Researchers in northern Ohio are predicting a significant bloom of toxic blue-green algae this summer, but they add that it will not be as large as the record-setting 2011 bloom.
Following an assessment by the US Fish and Wildlife Service, the eastern hellbender, a two-foot long aquatic salamander, could be added to the federal list of endangered species.
On NASA's famed Apollo 11 mission to the moon, astronaut Buzz Aldrin said he spotted a light traveling alongside his spacecraft. In a very narrow sense of the term, the light qualified as a UFO.
Herds of duck-billed dinosaurs in what is today Alaska's Denali National Park left behind 'one of the great track sites of the world.'
Researchers discovered a hotspot of high-energy particles that could offer clues about origin of cosmic rays.
A new colorful map reveals in detail the galactic dust that permeates our galaxy.
Oceanographers spotted a dark, swirling mass in shallow waters off the coast of San Diego. It wasn't a red tide or an oil spill, but a massive school of anchovies.
A single gene in a multicellular alga could offer clues for the genetic origins of the sexes.
A fossil site in British Columbia has yielded its first ancient mammals, including a miniature tapir and a hedgehog smaller than a mouse.
Researchers used fossils of an ancient arachnid to create a video simulating how the creature may have moved.
Data from Voyager 1 indicates that the spacecraft has exited the heliosphere, a bubble of plasma blown out by the sun.
Pelagornis sandersi's size exceeds some predictions of the maximum size for flying birds, note researchers.
A distinct inner ear bone formation thought to be unique to Neanderthals has turned up in a very different sort of ancient human found in China.
A new fossil, Pelagornis sandersi, may have had the largest wingspan of any flying bird to exist, according to researchers. Once in the air, the humungous bird glided on air currents.
Using satellite data of how much water is stored in river basins, researchers say they have determined a new way to predict which rivers are likely to flood.
Gravity data gathered by NASA's Cassini probe suggests that the subsurface ocean of Saturn's largest moon, Titan, has a remarkably high concentration of dissolved salts.
More than 500 marine fossils, including giant shark teeth and portions of a whale skeleton, have been unearthed at the Calaveras Dam project in Fremont, Calif.
Tibetans are adapted to rarefied air thanks to a gene passed down from the Denisovans, a group of extinct humans markedly distinct from our own species.
