Scientists have discovered chemically confirmed traces of ancient blood inside 115-million-year-old dinosaur bones, challenging assumptions about how long biological molecules can survive.…

A mysterious little blue octopus discovered nearly 6,000 feet beneath the waters of the Galápagos Islands has officially been identified as a brand-new species.…

A sea slug smaller than a sesame seed has turned up in Taiwan’s coastal waters — and it’s so tiny and unusual that scientists realized they had discovered a completely new species.…

Scientists revisiting mysterious 540-million-year-old microfossils from Brazil have overturned a major idea about early animal life. What were once thought to be trails left behind by tiny worm-like creatures are now believed to be fossilized communities…

Fur seals may look like they’re simply resting after exhausting hunting trips at sea, but their bodies are secretly working overtime. Scientists discovered that hours after returning to land, the seals’ heart rates suddenly surge — sometimes doubling — as…

New experiments suggest that freezing and thawing on early Earth may have helped primitive cell-like structures grow and evolve. Tiny lipid bubbles behaved very differently depending on their membrane makeup—some fused into larger compartments and…

A long-standing mystery in southern Africa’s fossil record is beginning to unravel. After massive lava flows 182 million years ago seemed to erase evidence of dinosaurs in the region, scientists have now uncovered surprising new clues along the Western…

Unlike most of its invertebrate peers, octopuses gave up protective shells... But it seems that the sacrifice was totally worth it.

Bull sharks may have a reputation as lone hunters, but new research reveals they actually form social bonds and even have preferred “friends.” After six years of observing 184 sharks in Fiji, scientists discovered these animals don’t just mix…
