Watch an Army of Ants Use Teamwork to Take Down a Millipede

Bigger isn’t always better, even in nature’s food chain. Take, for example, the video below, which features a group of tropical ants making a meal out of a millipede. Recorded by scientists in Cambodia and first reported by WIRED, the footage captures the tiny insects as they gang up on the arthropod and band together to paralyze it. Then, the victorious ants link together and form a long, rope-like chain with their bodies to carry the millipede off to its presumed end.

The ants belong to the genus Leptogenys, and they're a type of "swarm raider," according to an article published in the journal Insectes Sociaux, the journal of the International Union for the Study of Social Insects (IUSSI) [PDF]. Leptogenys ants are unique because they hunt millipedes and the occasional earthworm, using their intricate chains to drag away stunned prey weighing up to nearly .60 ounces. A Leptogenys chain can consist of anywhere from two to 52 ants.

In the video below, so many critters participate in the predatory act that their linked formation actually splits into sub-chains, as other insects crowd along the millipede’s sides. Scientists think these stragglers might actually be helping their peers by pushing, pulling, or lifting the millipede.

While impressive, Leptogenys ants are by no means the only animals whose predatory or defensive abilities far exceed their size. For example, larvae of the Epomis ground beetle consume frogs and toads. Honey badgers can fend off packs of lions. And a type of spider wasp called the tarantula hawk will stun a tarantula with its sting then drag it off to a burrow and lay an egg inside it. Nature is filled with tiny surprises, even if they are occasionally brutal ones.

Looking to Downsize? You Can Buy a 5-Room DIY Cabin on Amazon for Less Than $33,000

Five rooms of one's own.

If you’ve already mastered DIY houses for birds and dogs, maybe it’s time you built one for yourself.

As Simplemost reports, there are a number of house kits that you can order on Amazon, and the Allwood Avalon Cabin Kit is one of the quaintest—and, at $32,990, most affordable—options. The 540-square-foot structure has enough space for a kitchen, a bathroom, a bedroom, and a sitting room—and there’s an additional 218-square-foot loft with the potential to be the coziest reading nook of all time.

You can opt for three larger rooms if you're willing to skip the kitchen and bathroom.Allwood/Amazon

The construction process might not be a great idea for someone who’s never picked up a hammer, but you don’t need an architectural degree to tackle it. Step-by-step instructions and all materials are included, so it’s a little like a high-level IKEA project. According to the Amazon listing, it takes two adults about a week to complete. Since the Nordic wood walls are reinforced with steel rods, the house can withstand winds up to 120 mph, and you can pay an extra $1000 to upgrade from double-glass windows and doors to triple-glass for added fortification.

Sadly, the cool ceiling lamp is not included.Allwood/Amazon

Though everything you need for the shell of the house comes in the kit, you will need to purchase whatever goes inside it: toilet, shower, sink, stove, insulation, and all other furnishings. You can also customize the blueprint to fit your own plans for the space; maybe, for example, you’re going to use the house as a small event venue, and you’d rather have two or three large, airy rooms and no kitchen or bedroom.

The Psychological Tricks Disney Parks Use to Make Long Wait Times More Bearable

No one goes to Disneyland or Disney World to spend the day waiting in line, but when a queue is well-designed, waiting can be part of the experience. Disney knows this better than anyone, and the parks' Imagineers have developed several tricks over the years to make long wait times as painless as possible.

According to Popular Science, hacking the layout of the line itself is a simple way to influence the rider's perspective. When a queue consists of 200 people zig-zagging around ropes in a large, open room, it's easy for waiting guests to feel overwhelmed. This design allows riders to see exactly how many people are in line in front of them—which isn't necessarily a good thing when the line is long.

Imagineers prevent this by keeping riders in the dark when they enter the queue. In Space Mountain, for example, walls are built around the twisting path, so riders have no idea how much farther they have to go until they're deeper into the building. This stops people from giving up when they first get in line.

Another example of deception ride designers use is the "Machiavellian twist." If you've ever been pleasantly surprised by a line that moved faster than you expected, that was intentional. The signs listing wait times at the beginning of ride queues purposefully inflate the numbers. That way, when a wait that was supposed to be 120 minutes goes by in 90, you feel like you have more time than you did before.

The final trick is something Disney parks are famous for: By incorporating the same level of production design found on the ride into the queue, Imagineers make waiting in line an engaging experience that has entertainment value of its own. The Tower of Terror queue in Disney World, which is modeled after a decrepit 1930s hotel lobby down to the cobwebs and the abandoned coffee cups, feels like it could be a movie set. Some ride lines even use special effects. While waiting to ride Star Wars: Ride of the Resistance in Galaxy's Edge, guests get to watch holograms and animatronics that set up the story of the ride. This strategy exploits the so-called dual-task paradigm, which makes the line feel as if it's going by faster by giving riders mental stimulation as they wait.

Tricky ride design is just one of Disney's secrets. Here are more behind-the-scenes facts about the beloved theme parks.
