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.

On an old episode of "The Oprah Winfrey Show" in July 1992, Oprah put her audience through a social experiment that puts racism in a new light. Despite being nearly two decades old, it's as relevant today as ever.

She split the audience members into two groups based on their eye color. Those with brown eyes were given preferential treatment by getting to cut the line and given refreshments while they waited to be seated. Those with blue eyes were made to put on a green collar and wait in a crowd for two hours.

Staff were instructed to be extra polite to brown-eyed people and to discriminate against blue-eyed people. Her guest for that day's show was diversity expert Jane Elliott, who helped set up the experiment and played along, explaining that brown-eyed people were smarter than blue-eyed people.

Watch the video to see how this experiment plays out.

Cadbury has removed the words from its Dairy Milk chocolate bars in the U.K. to draw attention to a serious issue, senior loneliness.

On September 4, Cadbury released the limited-edition candy bars in supermarkets and for every one sold, the candy giant will donate 30p (37 cents) to Age UK, an organization dedicated to improving the quality of life for the elderly.

Cadbury was prompted to help the organization after it was revealed that 225,000 elderly people in the UK often go an entire week without speaking to another person.

Well Being

Young people today are facing what seems to be greater exposure to complex issues like mental health, bullying, and youth violence. As a result, teachers are required to be well-versed in far more than school curriculum to ensure students are prepared to face the world inside and outside of the classroom. Acting as more than teachers, but also mentors, counselors, and cheerleaders, they must be equipped with practical and relevant resources to help their students navigate some of the more complicated social issues – though access to such tools isn't always guaranteed.

Take Dr. Jackie Sanderlin, for example, who's worked in the education system for over 25 years, and as a teacher for seven. Entering the profession, she didn't anticipate how much influence a student's home life could affect her classroom, including "students who lived in foster homes" and "lacked parental support."

Dr. Jackie Sanderlin, who's worked in the education system for over 25 years.

Valerie Anglemyer, a middle school teacher with more than 13 years of experience, says it can be difficult to create engaging course work that's applicable to the challenges students face. "I think that sometimes, teachers don't know where to begin. Teachers are always looking for ways to make learning in their classrooms more relevant."

So what resources do teachers turn to in an increasingly fractured world? "Joining a professional learning network that supports and challenges thinking is one of the most impactful things that a teacher can do to support their own learning," Anglemyer says.

A new program for teachers that offers this network along with other resources is the WE Teachers Program, an initiative developed by Walgreens in partnership with ME to WE and Mental Health America. WE Teachers provides tools and resources, at no cost to teachers, looking for guidance around the social issues related to poverty, youth violence, mental health, bullying, and diversity and inclusion. Through online modules and trainings as well as a digital community, these resources help them address the critical issues their students face.

Jessica Mauritzen, a high school Spanish teacher, credits a network of support for providing her with new opportunities to enrich the learning experience for her students. "This past year was a year of awakening for me and through support… I realized that I was able to teach in a way that built up our community, our school, and our students, and supported them to become young leaders," she says.

With the new WE Teachers program, teachers can learn to identify the tough issues affecting their students, secure the tools needed to address them in a supportive manner, and help students become more socially-conscious, compassionate, and engaged citizens.

It's a potentially life-saving experience for students, and in turn, "a great gift for teachers," says Dr. Sanderlin.

"I wish I had the WE Teachers program when I was a teacher because it provides the online training and resources teachers need to begin to grapple with these critical social issues that plague our students every day," she adds.

In addition to the WE Teachers curriculum, the program features a WE Teachers Award to honor educators who go above and beyond in their classrooms. At least 500 teachers will be recognized and each will receive a $500 Walgreens gift card, which is the average amount teachers spend out-of-pocket on supplies annually. Teachers can be nominated or apply themselves.

One of the major differences between women and men is that women are often judged based on their looks rather than their character or abilities.

"Men as well as women tend to establish the worth of individual women primarily by the way their body looks, research shows. We do not do this when we evaluate men," Naomi Ellemers Ph.D. wrote in Psychology Today.

Dr. Ellers believes that this tendency to judge a woman solely on her looks causes them to be seen as an object rather than a person.
