See ferrofluid falling on a magnet filmed at 1000fps. How does the science of falling ferrofluid droplets mimic speghettification while falling into a black hole? Find out in this video from the always amazing Physics Girl. [Physics Girl]
You’ve probably heard that taking vitamin C or zinc will keep you from getting sick, but it turns out that those popular cure-alls don’t actually work. [SciShow]
Raindrops and snowflakes generally start to form around something else in the air, like a speck of dust, but sometimes that something else is bacteria. [SciShow]
Oxytocin is a hormone that plays a big role in maternal bonding and trust, and according to certain studies, also makes dogs more interested in smiling human faces and makes them feel less threatened by angry faces. [Source: Einstein’s mama on Facebook]
A newly created glass polymer can ‘heal itself’ without the need for extreme heat. But suggestions it could be used for phone screens might be a reach. Several polymers already exist with self-healing properties, meaning that with the application of heat they can reform their bonds and thus repair cracks. Aside from the fact that […]
From Warped Perception: I take the Whoosh Jet Bottle to a different level in this viewer request episode by burning Nitromethane, I have never seen Nitromethane burned in a whoosh bottle before ever, so I was very curious to see what will happen and it looked amazing. I figured since I’m working on so many […]
Are microwaves really just a form of light? What exactly is the electromagnetic spectrum? A science-mad A.I. system (voiced by GLaDOS actress Ellen McLain) uses song to explain this to a computer technician (Ed Wasser). With Casey McKinnon & Mike Romo. [Universe Unplugged]
Meteorologist Keith Carson rips the the flat earth theory in under 5 minutes. [keithcarsonmet]
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]
