Science advocate Bill Nye promotes his new PBS special with Vanity Fair with a jaunt through various scientific  terms like “arsole,” “hinny,” “champagne tap” and more.


Stephen Zheng (with the assistance of a cartoon woodland creature) explains the science and history of anaesthesia for Ted-Ed.

Spoiler: it may seem like you’re asleep, but you’re not.


Two 1998 observations of Jupiter’s icy moon Europa by the Galileo spacecraft stitched together by NASA engineer Kevin Gill. He geeks off thus:

Processed using low resolution color images (IR, Green, Violet) from March 29 1998 overlaying higher resolution unfiltered images taken September 26 1998. Map projected to Mercator, scale is approximately 225.7 meters per pixel, representing a span of about 1,500 kilometers.


The Great Filter – one possible reason why we may never detect another extraterrestrial civilisation in the observable universe (everyone chill, it’s just a theory). Kurzgesagt says:

Finding alien life on a distant planet would be amazing news – or would it? If we are not the only intelligent life in the universe, this probably means our days are numbered and doom is certain.

With Oumuamua currently hurtling through the solar system, YouTuber Reigarw Comparisons brings some perspective to various asteroid impacts on the surface of our home planet. To wit:

In this episode, we compare the impact of the sizes of asteroids from 1m to 1000km large, how often they occurred and what are the results. Including the Chelyabinsk Meteor, the Tunguska Meteorite airburst and the KT Extinction Event (bye-bye dinosaurs) Chicxulub Asteroid.


An in-depth exploration of movie timeshifting by Minute Physics. To wit:

…how time travel functions in different popular movies, books, & shows – not how it works “under the hood”, but how it causally affects the perspective of characters’ timelines (who has free will? can you change things by going back to the past or forwards into the future?).

The clever folk at Kurzgesagt – In A Nutshell explore the microbiome outside and inside all of us, explaining how – among other things – gut bacteria ‘talk’ directly to our brains.
