Mosquitoes are the world’s deadliest animal because they spread diseases like malaria and dengue. Scientists have developed a fascinating way to reduce this threat – infecting mosquitoes with Wolbachia, a bacteria that limits mosquitoes’ ability to carry other diseases. To jumpstart the process, they’re releasing millions of infected bugs. AsapSCIENCE explains.
Imagine, for a moment, that it was possible to pitch a baseball at 90% of the speed of light. Not only would you easily eliminate the batter, but there would be other major consequences according to this hypothetical physics exploration by the mighty Randall Munroe of xkcd. Weapons makers, don’t get any funny ideas.
According to the National Earthquake Information Center, there are roughly 20,000 earthquakes around the Earth every year. This fascinating animation from the NOAA, NWS, and Pacific Tsunami Warning Center shows every earthquake and tsunami recorded from January 1901 through December 2020. There’s also a spherical version that ends in 2000.
Have you ever wondered how the gravity on different planets might affect your ability to throw a ball? Dr. James O’Donoghue created this infographic that explores how far and high you could toss a ball, assuming no air resistance. Basically, on Mars, Mercury, and Pluto, you could hit a home run without a baseball bat.
Journey to the Microcosmos explores whether it is possible for microorganisms to spontaneously generate out of thin air. With the help of a powerful microscope and modern scientific knowledge, host Hank Green explains what’s really going on when microscopic organisms seem to show up where there was no life before.
We rely on batteries to power everything from our watches to our phones to our vehicles. But where did batteries come from, and who invented them? Origins explores the history of batteries and their evolution since 1799. Along the way, you learn we don’t see “B” cell batteries and what frog legs and torpedo fish have to do with it all.
Imagine, if you will, that the entire 4.5 billion year history of the Earth was collapsed down to a 24-hour single day. Bright Side’s educational video does just that, taking significant events in the development of our world and giving us a relative sense of how closely together they played out.
Video games have been simulating way that organisms thrive, evolve, and die ever since 1970 with John Conway’s, Game of Life. Over the years, simulations have become far more sophisticated but don’t always produce realistic results. Curious Archive looks at the strange evolution of games that simulate life.
Despite their lack of wings, spiders can actually take flight. This video from the University of Bristol video explains a process called ballooning, in which spiders take advantage of static electrical charges and wind currents to carry silk – and their bodies – through the air.
When you think about something being microscopic, it all seems the same size from our perspective. But this video from RED SIDE cleverly demonstrates the vast differences in the size of things we can’t see with the naked eye, from the tiniest atom to the relatively gargantuan amoeba. Also, there are way too many viruses.
An assassin’s teapot is a trick vessel that was designed to let its user serve a safe drink to themselves and a deadly one to their victim. And while you should never do such a thing, it’s fascinating to see how one works. Science educator Steve Mould shows us the physics at work, and inspired us to use one of these to serve drinks at cocktail parties.
The opposing forces of magnets can produce a tremendous amount of energy, and can even be used to levitate and move trains along a track. In this clip from Magnetic Games, he demonstrates these physics at work, though on a smaller scale using a bunch off-the-shelf neodymium magnets he got from Supermagnete.
After a series of heavy downpours this week, our neighborhood has lots of puddles. In a couple of days, these stagnant pools of water will be teeming with minuscule creatures. Journey to the Microcosm gets us up close and personal with some of these tiny organisms through the optics of high-power microscopes.
Did you know that putting ink from a ballpoint pen on the tail of a leaf turns it into a tiny, self-propelled boat? Science educator Steve Mould digs into this phenomenon and explores the chemistry and physics at work to make these leaf boats move and leave a trail of ink on the surface.
Unlike US paper sizes, metric paper sizes like A3 and A4 can be folded into quarters to make smaller standard size sheets. CGP Grey explains the satisfying math of this paper sizing standard, then zooms in and out to see how it relates to the exponential nature of the universe.
Kurzgesagt has a long history of exploring existential threats. Like many revolutionary changes, biotechnology can be used to improve civilization or bring it to its knees. In this video, they talk about how rapid advancements could wipe us all out by engineering an unstoppable virus, then propose some things we could do to limit those risks.
If you stand under an umbrella-shaped fountain, you can stay dry from the water over your head. But the idea of an umbrella made out of water seems ridiculous. James from The Action Lab tested the idea to see if the laminar flow of water coming from the umbrella would deflect raindrops away, or if they’d still get wet.
From a flaming bubble vortex to manipulating water with sound waves to balancing coins on a strand of thread, Mr. Hacker is here to show us more than 30 simple yet effective tricks and illusions enabled by the power of physics. Kids, don’t try that balloon-swallowing trick at home.
There’s data out there that helps scientists simulate what happens after an explosion gets going, but they still don’t fully understand how to simulate the genesis of a blast. Tom Scott visited a team at the UK’s University of Sheffield working on solving this problem, which could improve the safety of handling explosives and bomb disposal.
