By Andrew Freedman, CNN (CNN) — The human fingerprint on global warming was likely evident in Earth’s atmosphere far earlier than previously thought—even before the invention of modern cars, a new study says. Using a combination of scientific theory, modern observations and multiple, sophisticated computer models, researchers found a clear signal of human-caused climate change

By Ashley Strickland, CNN (CNN) — Scientists have identified a previously unknown 86 million-year-old dinosaur species that fills an early gap in the fossil record of tyrannosaurs, revealing how they evolved to become massive apex predators. Researchers analyzing the species’ remains have named it Khankhuuluu mongoliensis, which translates to “dragon prince of Mongolia,” because it

By Laura Paddison, CNN (CNN) — The collapse of a crucial network of Atlantic Ocean currents could push parts of the world into a deep freeze, with winter temperatures plunging to around minus 55 degrees Fahrenheit in some cities, bringing “profound climate and societal impacts,” according to a new study. There is increasing concern about

By Jack Guy, CNN (CNN) — Scientists studying ancient human remains uncovered in Colombia have found that the people they were researching have no known ancestors or modern descendants. In a study published May 30 in the journal Science Advances, a team of researchers reported on the genetic data of 21 individuals whose skeletal remains

By Jacopo Prisco, CNN Many of the Dead Sea Scrolls, some of the most widely known archaeological finds of all time, may be older than once thought, according to a new study. The fresh analysis, which paired radiocarbon dating with artificial intelligence, determined some of the biblical manuscripts date to about 2,300 years ago, when
