The tale of Europeans explorers’ arrival in the Americas is a dark one, colored by slavery, slaughter, and smallpox. But a new study calls key details of that story into question, including how quickly Native American societies succumbed to disease, and how Earth’s climate responded.
Sixty-five million years ago, an asteroid six miles in diameter cannoned into Earth. The collision triggered the catastrophic downfall of a vast and thriving dinosaurian ecosystem, ultimately ending with their extinction. Only that's not what happened. Not

But a few years ago, scientists discovered that microscopic structures called melanosomes could be used to reveal prehistoric creatures' true hues.
One of the largest paleontological finds in history has been discovered in the United Arab Emirates. Researchers working in the country's deserts have uncovered a massive tract of land riddled with the footprints of four-tusked titans called Stegotetrabelodon syrticus — the earliest known members of the elephant…
Many have marveled at the strange beauty of the tiny "tree islands" of the Florida everglades. How did they get there? Why do such small piles of land manage to sustain such healthy trees? Today, McGill paleoecologist Gail Chmura answered that question. Her research suggests strongly that the trees were originally…

Global warming often evokes images of melting icecaps, disappearing landmasses, and natural disasters. But the results aren't always so dire. For the Incas, global warming meant 400 years' prosperity and growth, allowing them to create a formidable empire.
