New research this week is adding fresh detail to one of paleontology’s biggest questions: Did dinosaur blood run hot or cold? Clues from fossilized eggshells and bones have now suggested that some dinosaurs were warm-blooded and others were not. Reinhard Dirscherl/ullstein bild/Getty ImagesMarine scientists have used artificial intelligence to decode previously unknown complexity in the calls of sperm whales. The whales produced a catalog of clicking sounds, which the researchers described as akin to a “phonetic alphabet” for sperm whales. What sperm whales are saying with their clicks remains a mystery to human ears, but understanding the scope of their vocal exchanges is an important step toward linking their calls with specific behavior.

Now, after the lab team’s decade of close collaboration with scientists at Google, that data has turned into the most detailed map of a human brain sample ever created. The result is an interactive 3D model of the brain tissue, and the largest dataset ever made at this resolution of a human brain structure. And of course, it would reveal many more problems, things we hadn’t expected.”What about mapping an entire human brain? “Much of what we think we understand about the human brain is extrapolated from animals, but research like this is critical for revealing what truly makes us human. “Each human brain is a vast network of billions of nerve cells,” said Sporns, distinguished professor of psychological and brain sciences at Indiana University.
