If that title doesn’t get your attention, we don’t know what will. In this video from Journey to the Microcosmos, they get up close and personal with a flowing river of human blood cells. It’s amazing to see how the individual cells dancing about and to learn about the characteristics of blood that keep us alive.
THE BEST Biology
Tardigrades may only measure about 0.5mm long, but these teensy water-dwelling critters are some of the toughest organisms known to humankind, having survived exposure to nuclear radiation and the vacuum of space. Zefrank provides an in-depth look at these strange, see-through dudes and what makes them tick.

This series of three jigsaw puzzles come together to form the major anatomical structures of a 5-foot-tall human being. Choose from head, thorax, or abdominal sections, each certified for accuracy by medical illustrator Mesa Schumacher. They make a great gift for biology students, or just anyone interested in science.
If you’ve ever visited one of Disney’s theme parks, you have been tricked. The parks frequently employ an optical illusion known as forced perspective to make structures look bigger or smaller than they actually are. Art of Engineering explains the trickery and why our brains get so easily fooled by it.
Conventional wisdom might lead you to believe that the largest living thing on Earth was some kind of whale. But scientists say there’s something much larger, and it’s land-locked in the middle of Utah. Alex Rosenthal of TED-Ed digs into the story of Pando, what caused it to become so enormous, and the risks it now faces.
If you’ve ever gotten gored by your adorable little kitty cat’s hook-like claws, you know how sharp they can be. Science educator Kyle Hill explains the biology behind cat claws, what makes them different from our fingernails, and how they manage to stay so razor-sharp.
Using high-precision digital models and laser etching techniques, CinkS labs is creating a series of glass cubes which display intricate 3D images of viruses, bacteria, and cells. The crystal cubes come in 3cm, 7cm, and 10cm sizes, as well as an 8cm sphere. And yes, they even have a COVID-19 model.
The human body is an amazing organic machine that performs countless tasks every minute of every day. In this video from The Infographics Show, they tally up some of the things that your body will do in the next minute – or twice as much while you watch the entire 2 minute clip.
If you’ve ever seen a beehive up close, you know how its made up of hundreds of nearly perfect hexagonal cells. Why is that, and how do bees know how to make such perfect geometry? TED-Ed provides a brief explanation of this strange intersection of evolutionary biology and architecture.
Researchers from The University of Vermont and Tufts University have created tiny “xenobots,” which use living cells manipulated to perform tasks. AI algorithms guided the microsurgery used to create these organic machines which could someday clean microplastics from oceans, or repair organs in our bodies.
This new channel is a collaboration by SciShow host Hank Green, musician Andrew Huang, and microorganism enthusiast James Weiss. It delves deep into the world of the trillions of microscopic organisms that surround us. We recommend starting off with Meet the Microcosmos for a primer to this fascinating universe.
There’s an oft-repeated story among school children that if you managed to keep your eyeballs open while sneezing, that they’d pop right out of their sockets. SciShow digs into this little gem to see if there’s any reason to actually be worried the next time you let out an atchoo.
(PG-13: Language) When you think of it, the skeletons of all creatures are a little weird looking, but some are definitely weirder than others. Tune in to this lesson from the Sam O’Nella Academy and enjoy 10 of the worst bone designs that mother nature has bestowed upon the world.
You might think that mammals always ate meat, but it turns out it was an evolutionary necessity due to changes in Earth’s climate. Kurzgesagt explores whether or not this change in our diets was actually good for us, or if eating meat truly has a negative impact on our health.
We wouldn’t be here on this planet if it weren’t for evolution – and a big part of the evolutionary process is natural selection. Primer presents a great 10 minute lesson on how the whole “survival of the fittest” thing works, along with a visual simulation with little blobby creatures.
