What is a species? That's not a simple question.
And it's even harder to answer after you've had a few.
Intrepid science journalist Charles Q. Choi takes inspiration from both the Drunk History series of videos and a really awful lot of whiskey to try and help you better understand a scientific concept (and also the finer points of orc biology). This was an idea I had, which came together with the help of several science journalist friends during the Science Online conference back in January. I'm still impressed with how accurate Charles was on the science while in that state. I can't speak to the Tolkien mythology.

Thanks to Rose Eveleth, Colin Schultz, and Jennifer Honn — whose work on editing and producing this video was invaluable. Also thanks to John Rennie, Steve Ashley, Olivia Koski, Maki Naro, and Stephen Granade — whose input and assistance made this possible.

Researchers successfully revived ancient microbes, some more than 100 million years old, that were buried in the seafloor. During an expedition to the South Pacific Gyre, the scientists from the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) and their colleagues drilled into the ocean sediment almost 6,000 meters below the surface. “Our main question […]
My family stopped wiping down all our groceries to “disinfect” them a couple months ago, mostly because of hygiene exhaustion. Then in May, the Center for Disease Control and Prevention clarified its own Web page about how COVID-19 spreads to state that “based on data from lab studies on COVID-19 and what we know about […]
I’d totally go.
Creating a fantasy world for a video or role-playing game is tough enough. In addition to all the game framework and functionality that goes into a build of any size, creators invariably sweat over the most minute details of every weapon, outfit, or other distinctive objects in their game. Even if your game is set […]
We get it. You don’t have to go to the office anymore. That’s no excuse for letting your grooming go positively feral. We’re not saying you need to be GQ cover model-ready every Monday through Friday. But at least put in some effort to keep yourself relatively trimmed, clean, and on point. Even if you […]
With everybody cooped up inside right now, it’s no surprise that many houses are starting to get a little bit…well, funky. Yeah…they smell. With everybody running around and sweating and working and cooking and everything else, odors get trapped inside your home. And don’t even get us started on what happens when litter boxes and […]
