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.

Aging is a weird thing. We all do it—we truly have no choice in the matter. It's literally how time and living things work.

But boy, do we make the process all kinds of complicated. The anti-aging market has created a 58.5 billion-dollar industry, with human beings spending their whole lives getting older spending buttloads of money to pretend like it's not happening.

I'm one of those human beings, by the way, so no judgment here. When I find a product that makes me look as young as I feel inside, I get pretty giddy.

But there's no doubt that our views on aging—and by extension, our perspectives on our own aging bodies—are influenced by popular culture. As we see celebrities in the spotlight who seem to be ageless, we enviously tag them with the hashtag #aginggoals. The goal is to "age well," which ultimately means looking like we're not aging at all. And so we break out the creams and the serums and the microdermabrasion and the injections—even the scalpel, in some cases—to keep the wrinkles, crinkles, bags, and sags at bay.

There's a big, blurry line between having a healthy skincare routine and demonizing normal signs of aging, and we each decide where our own line gets drawn.

This is where Justine Bateman comes in.

Since March of 2020, over 29 million Americans have been diagnosed with COVID-19, according to the CDC. Over 540,000 have died in the United States as this unprecedented pandemic has swept the globe. And yet, by the end of 2020, it looked like science was winning: vaccines had been developed.

In celebration of the power of science we spoke to three people: an individual, a medical provider, and a vaccine scientist about how vaccines have impacted them throughout their lives. Here are their answers:

When John Scully was born, America was in the midst of an epidemic: tens of thousands of children in the United States were falling ill with paralytic poliomyelitis — otherwise known as polio, a disease that attacks the central nervous system and often leaves its victims partially or fully paralyzed.

"As kids, we were all afraid of getting polio," he says, "because if you got polio, you could end up in the dreaded iron lung and we were all terrified of those." Iron lungs were respirators that enclosed most of a person's body; people with severe cases often would end up in these respirators as they fought for their lives.

John remembers going to see matinee showings of cowboy movies on Saturdays and, before the movie, shorts would run. "Usually they showed the news," he says, "but I just remember seeing this one clip warning us about polio and it just showed all these kids in iron lungs." If kids survived the iron lung, they'd often come back to school on crutches, in leg braces, or in wheelchairs.

"We all tried to be really careful in the summer — or, as we called it back then, 'polio season,''" John says. This was because every year around Memorial Day, major outbreaks would begin to emerge and they'd spike sometime around August. People weren't really sure how the disease spread at the time, but many believed it traveled through the water. There was no cure — and every child was susceptible to getting sick with it.

"We couldn't swim in hot weather," he remembers, "and the municipal outdoor pool would close down in August."

Then, in 1954 clinical trials began for Dr. Jonas Salk's vaccine against polio and within a year, his vaccine was announced safe. "I got that vaccine at school," John says. Within two years, U.S. polio cases had dropped 85-95 percent — even before a second vaccine was developed by Dr. Albert Sabin in the 1960s. "I remember how much better things got after the vaccines came out. They changed everything," John says.
