Try not to jiggle while watching these amazing bladeless wind turbines.

The wind: A cool breeze, a breath of fresh air, a pollen delivery system.

When it's not inverting your umbrella, knocking over your pitcher of iced tea, or sadistically ushering a balloon away from a crying child, the wind is capable of doing some pretty powerful stuff.

Most notably, the wind can generate electricity, which, for the most part, involves turbines that look like this:

You've seen them, I'm sure. Those giant, futuristic looking propellors that slowly rotate and are the perfect tension-driving backdrop for a helicopter chase scene?

A startup in Spain called Vortex, however, has recently come up with a new design for the turbines. It looks like this:

It's called Bladeless, and it's a wind turbine with — you guessed it — no blades.

The bladeless turbines are massive poles jutting out of the ground. Because they're thinner than a regular wind turbine and have no blades, more of them can fit into a space, meaning more electricity can be generated while taking up less real estate.

So how does the bladeless turbine generate power?

Get this: It freaking jiggles.

Here it is from a different angle:

You're jiggling now too, aren't you? Come on, I know you are.

Besides being contagious and relatively adorable, as far as wind turbines go, that jiggle motion is actually based on a fascinating branch of science called aeroelasticity.

Aeroelasticity is the study of how elastic things move when exposed to constant energy — like how a bungie cord might fare in a tornado.

A good example of aeroelasticity-gone-wild happened in 1940 at the Tacoma Narrows Bridge in Washington state, when it was blasted with winds up to 40 mph. The suspension cables absorbed the impact but made the bridge vibrate and undulate, causing a positive feedback loop known as an aeroelastic flutter, where each vibration made the next vibration even worse.

The whole bridge started swinging wildly out of control, and then...

Thankfully, no one died, and engineers actually learned several important lessons about bridge design.

The designers of the bladeless turbine also learned something from the Tacoma Bridge disaster.

The bladeless turbine design actually captures the power of aeroelastic flutter and uses its magnified vibrations to create power from less wind than the old turbine designs could.

The company says that its design is 40% cheaper than traditional turbines because the huge blades those require are expensive. Plus, they expect upkeep to be cheaper since the bladeless turbines have fewer moving parts. Bladeless turbines will also be quieter and create less wind disturbance, which are both popular arguments against bladed turbines.

All of this is to say — we humans are getting better and better at harnessing the power of the wind.

Here in the United States, we're actually better at harnessing the wind to power people's homes than you might expect. There are currently over 48,000 wind turbines generating 74,512 megawatts of electricity in nearly every single state, which made the U.S. one of the top countries in wind energy in 2015.

All that clean energy, here and around the world, is (slowly) helping us reduce carbon emissions and fight back against climate change, and innovative ideas like the bladeless turbine are constantly seeking to make that process easier.

Maybe one day you'll look outside and see a hundred bladeless turbines jiggling happily away in the wind. And when, or if, that day comes, I bet you'll be jiggling too.

There's a difference between dieting and being healthy, and often times, overattention to what you consume can lead to disordered eating. Eating disorders are dangerous and can affect anyone, but they're especially concerning in adolescents. Which is why WW (formerly Weight Watchers) is facing intense criticism for its new app, Kurbo, targeted toward kids ages eight to 17.

The app uses a traffic light system to tell kids which foods are a "green light" and can be eaten as much as they want, which foods are a "yellow light" and should be consumed with caution, and which "red light" foods they should probably avoid.

It seems like a simple system to teach kids what's good for them and what's not, but it regulates kids' diets in an unhealthy way. Gaining weight is a normal, healthy part of child development. Putting on a few pounds means your body is doing what it's supposed to do. While the app classifies foods with too much fat or calories as "red," children need to consume some of these foods to develop their brain.

WW is calling the app "common sense." As Gary Foster, the chief science officer of WW, puts it, items in the red foods category "aren't foods that should be encouraged in kids' diets, but they also shouldn't be vilified or demonized, and there has to be a system that's simple and science-based that highlights that so everyone in the family can understand."

Upon arriving in the winter, she fell in love with the goldfinches, cardinals, and Blue Jays. Then in the spring, she was taken by the hummingbirds.

Service dogs are invaluable to their owners because they are able to help in so many different ways.

They're trained to retrieve dropped Items, open and close doors, help their owners remove their clothes, transport medications, navigate busy areas such as airports, provide visual assistance, and even give psychological help.

The service dog trainers at K-9 Country Inn Working Service Dogs in Canada want those who require service dogs to live the fullest life possible, so they're training dogs on how to attend a theatrical performance.

The adorable photos of the dogs made their way to social media where they quickly went viral.

On August 15, a dozen dogs from Golden Retrievers to poodles, were treated to a performance of "Billy Elliott" at the Stratford Festival in Ontario, Canada. This was a special "relaxed performance" featuring quieter sound effects and lighting, designed for those with sensory issues.

"It's important to prepare the dogs for any activity the handler may like to attend," Laura Mackenzie, owner and head trainer at K-9 Country Inn Working Service Dogs, told CBC.

"The theater gives us the opportunity to expose the dogs to different stimuli such as lights, loud noises, and movement of varying degrees," she continued. "The dogs must remain relaxed in tight quarters for an extended period of time."

The dogs got to enjoy the show from their own seats and took a break with everyone else during intermission. They were able to familiarize themselves with the theater experience so they know how to navigate through crowds and fit into tight bathroom stalls.

"About a dozen dogs came to our relaxed performance, and they were all extremely well-behaved," says Stratford Festival spokesperson Ann Swerdfager. "I was in the lobby when they came in, then they took their seats, then got out of their seats at intermission and went back — all of the things we learn as humans when we start going to the theater."

The dogs' great performance at the trial run means that people who require service animals can have the freedom to enjoy special experiences like going to the theater.

"It's wonderful that going to the theater is considered one of the things that you want to train a service dog for, rather than thinking that theater is out of reach for people who require a service animal, because it isn't," Swerdfager said.

The Stratford Festival runs through Nov. 10 and features productions of "The Merry Wives of Windsor," "The Neverending Story," "Othello," "Billy Elliot," "Little Shop of Horrors," "The Crucible" and more.
