Like a secular version of one of those crazy weeping Virgin Mary statues, Taylor Glacier in Antarctica* has been known for the blood-like liquid that pours from it since the "Blood Falls" was discovered in 1911.
The eerie waterfall cascades into one of Antarctica's dry valleys—snowless, barren wastes where almost nothing lives. (I wrote about the dry valleys for a BoingBoing feature last month.)
Aunt Flow—as I've just decided to call the Falls—gets its color from the dietary habits of microbes, which live in ancient seawater trapped beneath the glacier. They draw their energy from iron deposits leeched from the rocks the slowly moving glacier grinds to dust—leaving the water streaked rust red.
Even more awesome: This is one of the few places on Earth exobiologists can easily study the kind of extreme life—creatures that survive and thrive in incredibly cold, sunlight-free environments—that might also live on other planets.
*In between this and the frazil ice post, can you tell we got up above 90 F today in Minneapolis? And that I don't have air conditioning?
I’ve had quite a few fun afternoons playing with dry ice from making spooky fog in the kitchen to exploding plastic bottles in the yard. But I’ve never had the opportunity to pour hot lava over dry ice. In this video, the lava is 1400 °C and the dry ice is -78C°. So cool! And […]
A Boston University team have developed an acoustic, 3D-printed metamaterial whose topology is such that it reflects 94% of human-audible sound; the researchers' demonstration involves inserting a ring of this stuff in a PVC pipe and blasting a speaker down one end: light and air emerges from the other end, but sound does not.
Scientists Lior Appelbaum and David Zada in Israel publish new proof that sleep serves to help our brains repair damage.
Big companies want automation on a big scale. Doing that means diving into the tricky world of machine learning and data science. And no matter what platform you’ll be implementing it on, you can learn how with the Machine Learning & Data Science Certification Training Bundle. In 48 hours and through eight courses, this bundle […]
Big systems need tight security – and the experts who can implement it. Cisco Networking Systems are the go-to providers for network infrastructure, but maintaining it takes a lot of up-to-date knowledge. If you want that knowledge right from the source, there’s an online course that can get you certified painlessly: The Foundational Cisco CCNA […]
Computer slowing down? There are a ton of reasons why that might be, especially if your unit has a few years on it. Junk files and programs can accumulate over time, some even left over from otherwise uninstalled software. This virtual debris can slow your PC down dramatically, but there’s a surprisingly quick fix. Lauded […]
