In this week’s edition of SciShow news, Hank Green brings you discoveries involving two of the most exotic substances on Earth — the world’s rarest element and the world’s oldest water. Two great tastes that taste great together? Stay tuned to find out.
Bitten by a venomous snake? There’s hope! French scientist Albert Calmette developed the first snake antivenom in the late 1890s, and did such a good job that we use his technique to this day. Antivenom works by stimulating the production of antibodies that can smother venom’s toxic effects, preventing spread and rendering them harmless. But how do you make it? Well, stay tuned to this episode of SciShow to find out.
Google’s new Earth Engine, powered by NASA’s landsat satellites, gives a time lapse view of (pretty much) every land surface on earth over the last 25 years. The view is amazing, and inspiring, and at times terrifying. Hank Green reports.
Cicadas have developed an amazing strategy for growth, survival, reproduction, and overcoming predation by…doing nothing. They do nothing for years (except sip at the juice excreted from root structures) before emerging in huge, simultaneous swarms.
The swarm is so huge that predators can’t consume even a fraction of it, but so rare that predator populations can’t sustain themselves between emergence events. Clever little things!
Hank Green introduces us to 6 blood-drinking (or otherwise consuming) animals that you may not be aware of. Don’t freak out…
We’ve been trying to build flapping-wing robots for hundreds of years. And now, ornithopters are finally being developed, and may be used mostly for military purposes, says Hank Green of the SciShow.
Piezoelectrics make those little bugs possible, and also enhances the ability of robot arms to feel, in other news from The International Journal of Robotics.
Although polar bears and grizzly bears aren’t all that similar and are definitely separate species, they can interbreed and create fertile offspring in the wild. Hank Green brings us the story of these misfit bears, which he likes to call grolar bears.
Learning to talk about chemistry can be like learning a foreign language, but Hank Green is here to help with some straightforward and simple rules to help you learn to speak Chemistrian like a native.
Hank Green gives a quick run-down of the reasons scientists think the land mammals of today are nowhere near the size of the largest sauropods. Some of them might surprise you!
Science can help create understanding where there is none, but is it possible to study and understand terrorists if we’re too busy doing everything we can to stop it? Terrorism is notoriously difficult to study because governments constantly subpoena scientists’ lists of contacts, making source anonymity impossible. Hank Green comments.
