Sure, those might be a little pricey, but they are absolutely gorgeous and are hand-made by an actual artist. A Saturn that actually LOOKS like Saturn, with Cassini data used to etch the rings! A Sun with sunspots! Earth and Mars with clouds and polar caps, Jupiter with a red spot, and I include Pluto, […]
Nearly 350 species of fish have specialized anatomical structures that generate and detect electrical signals. Underwater, where light is scarce, electrical signals offer ways to communicate, navigate, find, and sometimes stun prey. But how do these fish produce electricity? And why? Eleanor Nelsen illuminates the science behind electric fish. [TED-Ed]
Filipino High school sudent Hillary Diane Andales recently won the 2017 Breakthrough Junior Challenge with her video explaining relativity and the equivalence of reference frames. The prize consists of a $250,000 post-secondary scholarship for her, and $50,000 for her teacher. The core concept of relativity is interesting in that it shatters the singularity in perspective […]
What is UBI and wow would free money change our lives? Learn all about it in this episode of “In a Nutshell.” [Kurzgesagt – In a Nutshell ]
Researchers say feeding graphene to spiders produces stronger webs. The researchers think it could mean new ways to make parachutes rather than it being the start of a cheap disaster movie. As we’ve covered many times, graphene is made of carbon atoms arranged in a chain of hexagons, somewhat like chicken wire. The material is […]
From Mark Rober: Fluidized beds are used in industry for various reasons. They also happen to be really cool to play with and swim in. I made a liquid sand hot tub by adding air in just the right way. [Mark Rober]
The human brain remains a complex mystery. But, if we dare to dream big—and have the proper tools and data to fuel those ambitions—we may one day discover cures for diseases as devastating as Alzheimer’s. At the German Center for Neurodegenerative Diseases (DZNE), more than 1,000 neuroscientists are using the latest technology to identify biomarkers […]
How much genetic diversity would we need to found a colony on another planet? This episode of Scishow takes a look a this very important question. [SciShow]
An architect will use the world’s darkest material to make a building that looks like somebody has ripped a hole in the horizon. The structure clad in Vantablack will be part of the Olympic Park in South Korea for next year’s Winter Games. Vantablack is made of carbon nanotubes, which are one-atom thick sheets of […]
Cochlear implants don’t generate sound like a hearing aid would. Instead, they zap your cochlea. Find out exacly how they work in this episode of SciShow. [SciShow]
