See the notches at the top of these two casts of ancient hominid mandibles? If you were a paleoanthropologist, you would spend your days arguing about the shape of those notches and their deeper possible meanings.
In 2010, the scientists who found these jaw bones decided that the bones represented a previously unknown hominid species — Australopithecus sediba — whose characteristics blend those of our genus, Homo, with those of a much older genus, Australopithecus.
BUT, now, writes Kate Wong, other scientists think they're wrong, arguing that the two bones don't even come from the same species. Instead, the top mandible in this picture could be straight up Homo, and the bottom classic Australopithecus, and the whole debate — which has implications for how we draw our human family tree — hinges on the shape of that, well, hinge.

To demonstrate the Magnus effect, YouTuber PeterSripol grabbed a couple of KFC buckets and tricked out an RC plane. The resulting trial and error is mostly the latter.
One of the weirdest places in Antarctica is Blood Falls, a five-story cascade of blood-red liquid pouring from Taylor Glacier. Researchers finally traced its source: a saltwater lake millions of years old trapped under the glacier.
Bamboo has lots of uses beyond just being panda food. Things like bikes, roads, scaffolding, and musical instruments are made from the fast-growing grass. But unless you are participating in a tropical-themed LARP, you probably wouldn’t want a shirt made from bamboo stalks. So why do bamboo bed sheets make any sense? Because yarn extracted from […]
If you want to work in tech, but don’t have any desire to code web apps to help businesses sell things to other business, you might want to consider a career in cybersecurity. Judging from the apparent complete infiltration of Russian hackers in American cyberspace, it seems fair to speculate that there’s a major shortage of […]
All moms are different. But all moms like getting flowers on Mother’s Day, and that’s a fact (not, however a fact we can document in any fashion.) Instead of getting chewed out for forgetting to call her on the second Sunday of May, you can take care of it ahead of time with Teleflora’s flower […]
