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.
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.
(Flashing lights) This fascinating short film from Joel Penner and Anna Sigrithur uses time-lapse footage to reveal how tiny organisms spoil food, others that make it tastier through fermentation, and yet more that compost and break down dead things to fertilize the Earth for new life.
When red fire ants find face flood waters, they quickly evacuate their tunnels and build a raft out of their bodies. This unique evolutionary trait helps the colony survive as a whole and is quite the sight floating atop flood waters in this video from Deep Look. You definitely wouldn’t want to swim up next to this thing.
The Holothuroidea, aka sea cucumber, is one of the many strange-looking creatures that dwell at the bottom of the ocean. ZeFrank explains the unusual way these spiny, slug-like things reproduce, develop, and thrive – along with just how diverse their species can be. Expect Frank’s usual mix of information and innuendo.
It’s been a while since we got a lesson from the Sam O’Nella Academy, but after a nearly 3-year hiatus from YouTube, the snarky educator takes us back to school to learn about scientific animal names and where they come from. Those taxonomy mnemonics are just as good as the ones on TV Funhouse.
The Universe is enormous. But here on earth, there’s a seemingly endless universe inhabited by insects, bacteria, plants, microorganisms, molecules, and atoms. Kurzgesagt zooms in beneath our feet for a journey to these tiny worlds among us, using the size of our world as a frame of reference.
Nature show host ZeFrank offers up a detailed look at a kind of amoeba known as Dictyostelium and explores how they work. These strange microscopic organisms gobble up bacteria and other tiny things, then divide over and over to reproduce. But the weirdest part is what they do once the colony runs out of food.
Science says that all living things are the result of evolution. But do species stop evolving at some point or do they keep changing? Joe from Be Smart explains what things influence these changes and the question of whether science, medicine, and technology have allowed humans to bend the laws of natural selection.
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.
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.
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.
