An enormous impact crater, hiding deep beneath Greenland’s Hiawatha glacier, is probably the result of a kilometer-wide asteroid that crashed into Earth 58 million years ago. That’s much older than scientists presumed – roughly eight million years after the infamous impact that killed off most dinosaurs. When the Hiawatha crater was first discovered in … Read more
Hidden under Greenland’s thick ice sheet, scientists found what they thought was the scar of an asteroid impact perhaps just thousands of years old, fresh enough that humans were already on the scene. But after several years of additional research, two separate teams of scientists have determined its age to be far older: 58 million … Read more

An exceptional fossil unearthed in Montana has given us the earliest known ancestor of vampire squids and octopuses. The cephalopod, belonging to the vampyropod or octopodiform superorder, pushes back the age of the group by about 82 million years. This challenges our understanding that octopuses evolved from a Triassic ancestor. Fascinatingly, it has not eight, … Read more
Scientists have developed a quick genetic test that can diagnose a large range of rare muscle and nerve diseases with near perfect accuracy. Tandem repeat disorders are a family of over 50 inherited diseases, including Huntington’s disease and amyotrophic lateral sclerosis (ALS), that seem to occur when short DNA sequences are repeated too many times. … Read more

1972 Surprise: Mars Volcano “Mars continues to surprise the investigators associated with Mariner 9, which has been in orbit around the planet since November 13. Perhaps the most spectacular feature is a volcanic cone at least 300 miles in diameter at the base, making it larger than any comparable feature on the earth. Close-ups of … Read more
Early Earth is often described as ‘Hadean’ for good reason. Arising from the ashes of a collision that gave us our Moon, the primordial eon was characterized by hellish heat trapped beneath a thick blanket of carbon dioxide and water vapor. Strangely those conditions should have been inhospitable for far longer than they were. … Read more

Scientists discovered remnants of an Old Stone Age culture, less than 100 miles (160 kilometers) west of Beijing, where ancient hominins used a reddish pigment called ochre and crafted tiny, blade-like tools from stone. The archaeological site, called Xiamabei, offers a rare glimpse into the life of Homo sapiens and now-extinct human relatives who inhabited the region some … Read more
