The far reaches of the outer solar system may be home to an icy giant — a hypothetical planet scientists have dubbed “Planet Nine.”
Reptilian menaces called Silurians evolved on Earth before humankind — at least in the “Doctor Who” rendition of the universe. But science fiction aside, how would we know if some advanced civilization existed on our home planet millions of years before brainy humans showed up?
Legions of metal nuggets swirl about our solar system. Metallic asteroids number in the millions, but they’re relatively quite rare—bits and pieces of lonely matter that never became planets.
Some experts have long believed that a massive asteroid was a primary cause of dinosaurs’ extinction some 65 million years ago, but new analysis from a University at Albany psychology professor suggests that the dinosaurs were in trouble long before the asteroid hit.
Parts of the Amazon previously thought to have been almost uninhabited were really home to thriving populations of up to a million people, new research shows.
Rare dinosaur footprints belonging to the largest animal to ever roam the planet have been found in Scotland. Dozens of the 170 million-year-old fossils, belonging to early sauropods, have been unearthed in a muddy lagoon on the Isle of Skye.
Researchers in several disciplines need to tread carefully over shared landscapes of the past.
The remains of dozens of fortified villages, built before the arrival of Europeans, have been found in a relatively remote region of the Amazon. It seems the southern periphery of the Amazon was home to a million people before 1500 AD – far more than assumed.
Burials from a cave in Morocco have yielded the oldest human DNA evidence yet from Africa, offering new insight into Stone Age migrations.
Ending a long-standing mystery that once set the unidentified flying object community abuzz, researchers have sequenced the entire genome of a strange, 15-centimeter-tall human skeleton and identified mutations that may be responsible for its odd appearance.
