Every now and then, you might see a story in the news about a “brain-eating amoeba” that turned up somewhere. But is this microscopic organism as terrifying as it sounds, or is it all just hyperbole? Kurzgesagt digs into the true story of the naegleria fowleri, and what it’s likely to do should it enter your body.
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.
Ants are well known for their ability to work together to build things and accomplish tasks for their colony. In this fascinating video from Horace Zeng, we see how hundreds of fire ants work in concert to pick up, move, and place pieces of glass gravel on a piece of sticky tape, resulting in a colorfully-paved road of sorts.
Live Science and physicist Anton Peshkov take us inside the microscopic world of the turbatrix aceti, otherwise known as the vinegar eel. These tiny nematodes thrive on the kind of microbes that transform juice into vinegar and wriggle around like tiny bolts of lightning as they cluster in a single droplet of water.
Nature can be pretty amazing. Take, for example, how this hive of honeybees discourages predators like wasps from attacking. Multiple layers of bees form a protective shield on the outside of their honeycomb and move in synchronized patterns that make the whole hive look like it’s one big creature.
When it comes to watching our diet, counting calories is one of the most common methods of tracking food intake. AsapSCIENCE explains how the nutritional composition of foods, our individual metabolisms, genetics, and microbiomes affect how we process food, impacting our health far more than calories alone.
Humans like to give flowers and chocolates as part of our dating ritual. Other species offer gifts as part of their courtship too, but their selections aren’t nearly as appealing. SciShow explains some of the strange and downright gross-out gifts that animals and insects present to each other as an offering to potential mates.
We’re so used to seeing octopi swimming, we sometimes forget that they can use their tentacles to walk too. Though in the case of this extraordinary cephalapod, he’s in a hurry and chooses to run to his destination. We just want to put this video on a loop and use it as our wallpaper.
Filmmaker Jan van IJken offeers a look at the microscopic world of plankton. These fascinating organisms can be found everywhere you find water and are a critical part of our ecosystem. Some provide food for marine life, while others produce oxygen through photosynthesis. Stream the full 15-minute version here.
Kurzgesagt explores the complex systems at work to help keep our 40 trillion cells alive and well, adapting and facing off countless times each day against foreign organisms teeming inside of our bodies. For a deeper dive, grab a copy of Kurzgesagt founder Phil Dettmer’s new book IMMUNE.
Thanks to movies like Jurassic Park, we have some very specific notions of what dinosaurs looked like. But as Kursgezagt explains, between missing fossils and misinterpreted skeletal reconstructions, it’s quite possible that these prehistoric animals appeared very different than we thought.
While we sit here staring at our screens, a war is being fought all around us. Trillions of microorganisms are battling it out for resources while viruses attack and take over. While it’s was believed that viruses aren’t alive, recent discoveries point to giant viruses that act more like living organisms. Kurzgesagt explains.
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.
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.
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.
