Earlier this year, a Swiss startup began removing CO2 from the atmosphere using a large vacuum-like machine.

Their ultimate goal is to start reversing the damaging effects of climate change by reducing CO2 — a major component of atmospheric pollution — on a global scale.

While the machine's development is a huge step forward, one little problem remains — where does all that collected CO2 go?


Gaurav Sant, a professor of civil and environmental engineering at UCLA, has one solution: turn it into cement.

Sant has figured out how to make a stronger, more lightweight, more structurally sound cement out of — wait for it — CO2.

Believe it or not, the regular construction of cement is responsible for 9% of the world's CO2 emissions. And it is widely accepted that CO2 emissions play a huge role in global warming and, by effect, climate change.

Sant, along with his team at UCLA, decided to try to turn two negatives into a positive. They found a way to integrate CO2 into the production of cement, thereby keeping it out of the atmosphere and upcycling it into something useful and even profitable.  

It all started from tiny cement cylinders created by Sant's 3D printer.

Well, that and a pretty important discovery of how CO2 can help accelerate the cement-making process.

In simplest terms, Sant's team discovered that the CO2 in flue gas streams from coal and natural gas power plants accelerates the mineral-making processes that can be used to create cementing agents. They decided to use CO2 to produce a new type of concrete that they've named CO2NCRETETM.

Curious how they did that? Here's the breakdown.

When a mineral called portlandite absorbs CO2, it turns into limestone, which is a cementing agent. While this process normally takes years to happen naturally, Sant's team figured out how to make it happen quickly — 450 pounds of CO2 into several tons of CO2NCRETETM quickly — and efficiently using their 3D printer.

Unlike traditional cement-making on a construction site, 3D technologies allow them to create basic construction pieces out of their new CO2-based concrete that fit together perfectly.

This means they can make cement pieces that are stronger, more lightweight, and more structurally sound.

"As a child that played with Legos, I have long recognized that the idea of constructing buildings and infrastructure like a large Lego set is (a) fast, (b) intuitive, and, (c) offers improved quality control since 'factory made' pieces are simply assembled on site," Sant explains in an email.  

What sort of impact could this have on reducing global CO2 emissions? Turns out, a pretty big one.

According to Sant and his team, if CO2NCRETETM were to be mass-produced globally, it could reduce CO2 emissions from traditionally made cement by 50%. And since those emissions currently make up 9% of all CO2 emissions on the planet, that's no small amount.

What's more, since there's been little change made in the construction industry over the last two centuries, it's primed for an efficiency makeover.

"CO2NCRETETM has the potential to serve as an example of how CO2 emissions — even those associated with dilute CO2 streams — can be repurposed to create value and minimize environmental impact," writes Sant.

And it's not like this goal is a faraway dream. They've made incredible progress on this new cement and are starting to shop it around.

They've figured out how to streamline the cement-making process so it takes much less time and energy than it did initially. They've also done an analysis of the construction market and see huge potential for such a sustainable product.

"This is especially significant as jurisdictions, globally, including states and nations, seek to limit CO2 emissions and impose CO2 penalties on industrial processes," writes Sant.

And in terms of progress with CO2 capture, Sant's work could offer an economically viable alternative to storing the CO2 underground, which can get pretty expensive.

If the world recognizes the economic value of upcycled cement along with the environmental impact, this discovery could revolutionize the future of construction.

Engineering solutions like this can offer a way to mitigate climate change and be profitable at the same time. Now it's just about keeping an open mind and seeing the enormous potential in a small, concrete cylinder.

As for Sant and his associates, they're just thrilled to be on the precipice of real, necessary change.

"As humans, we all want to make positive impact," says Sant. "To be a part of the solution is a very empowering accomplishment that we wish to socialize."

We're redefining what normal means in these uncertain times, and although this is different for all of us, love continues to transform us for the better.

Love is what united Marie-Claire and David Archbold, who met while taking a photography class. "We went into the darkroom to see what developed," they joke—and after a decade of marriage, they know firsthand the deep commitment and connection romantic love requires.

However, their relationship became even sweeter when they adopted James: a little boy with a huge heart.

In the United States alone, there are roughly 122,000 children awaiting adoption according to the latest report from the U.S Department of Health and Human Services. While the goal is always for a child to be parented by and stay with their biological family, that is not always a possibility. This is where adoption offers hope—not only does it create new families, it gives birth parents an avenue through which to see their child flourish when they are not able to parent. For the right families, it's a beautiful thing.

The Archbolds knew early on that adoption was an option for them. David has three daughters from a previous marriage, but knowing their family was not yet complete, the couple embarked on a two-year journey to find their match. When the adoption agency called and told them about James, they were elated. From the moment they met him, the Archbolds knew he was meant to be part of their family. David locked eyes with the brown-eyed baby and they stared at each other in quiet wonder for such a long time that the whole room fell silent. "He still looks at me like that," said David.

The connection was mutual and instantaneous—love at first sight. The Archbolds knew that James was meant to be a part of their family. However, they faced significant challenges requiring an even deeper level of commitment due to James' medical condition.

James was born with congenital hyperinsulinism, a rare condition that causes his body to overproduce insulin, and within 2 months of his birth, he had to have surgery to remove 90% of his pancreas. There was a steep learning curve for the Archbolds, but they were already in love, and knew they were committed to the ongoing care that'd be required of bringing James into their lives. After lots of research and encouragement from James' medical team, they finally brought their son home.

Today, three-year-old James is thriving, filled with infectious joy that bubbles over and touches every person who comes in contact with him. "Part of love is when people recognize that they need to be with each other," said his adoptive grandfather. And because the Archbolds opted for an open adoption, there are even more people to love and support James as he grows.

Cats are notoriously weird. Everyone who's had cats knows that they each have their own unique quirks, idiosyncrasies, preferences, habits, and flat-out WTFness.

But even those of us who have experience with bizarre cat behavior are blown away by the antics this "cat dad" is able to get away with.

Kareem and Fifi are the cat parents of Chase, Skye, and Millie—literally the most chill kitties ever. They share their family life on TikTok as @dontstopmeowing, and their videos have been viewed millions of times. When you see them, you'll understand why.

Take Chase's spa days, for example. It may seem unreal at first, but watch what happens when Fifi tries to take away his cucumber slices.

When she puts them back on his eyes? WHAT?! What cat would let you put them on once, much less get mad when you take them off?

This cat. Chase is living his best life.

But apparently, it's not just Chase. Skye and Millie have also joined in "spaw day." How on earth does one couple end up with three hilariously malleable cats?

Oh, and if you think they must have been sedated or something, look at how wide awake they are during bath time. That's right, bath time. Most cats hate water, but apparently, these three couldn't care less. How?

They'll literally do anything. The Don't Stop Meowing channel is filled with videos like this. Cats wearing glasses. Cats wearing hats. Cats driving cars. It's unbelievable yet highly watchable entertainment.

If you're worried that Kareem gets all the love and Fifi constantly gets the shaft, that seems to be a bit for show. Look at Chase and Fifi's conversation about her leaving town for a business trip:

The whole channel is worth checking out. Ever seen a cat being carried in a baby carrier at the grocery store? A cat buckled into a car seat? Three cats sitting through storytime? It's all there. (Just a heads up: A few of the videos have explicit language, so parents might want to do a preview before watching with little ones.) You can follow the couple and their cats on all their social media channels, including Instagram and YouTube if TikTok isn't your thing, here.

If you weren't a cat person before, these videos might change your mind. Fair warning, however: Getting a cat because you want them to do things like this would be a mistake. Cats do what they want to do, and no one can predict what weird traits they will have. Even if you raise them from kittenhood, they're still unpredictable and weird.

And honestly, we wouldn't have them any other way.

You know that feeling you get when you walk into a classroom and see someone else's stuff on your desk?

OK, sure, there are no assigned seats, but you've been sitting at the same desk since the first day and everyone knows it.

So why does the guy who sits next to you put his phone, his book, his charger, his lunch, and his laptop in the space that's rightfully yours? It's annoying!

There have been many iconic dance routines throughout film history, but how many have the honor being called "the greatest" by Fred Astaire himself?

Fayard and Harold Nicholas, known collectively as the Nicholas Brothers, were arguably the best at what they did during their heyday. Their coordinated tap routines are legendary, not only because they were great dancers, but because of their incredible ability to jump into the air and land in the splits. Repeatedly. From impressive heights.

Their most famous routine comes from the movie "Stormy Weather." As Cab Calloway sings "Jumpin' Jive," the Nicholas Brothers make the entire set their dance floor, hopping and tapping from podium to podium amongst the musicians, dancing up and down stairs and across the top of a piano.

But what makes this scene extra impressive is that they performed it without rehearsing it first and it was filmed in one take—no fancy editing room tricks to bring it all together. This fact was confirmed in a conversation with the brothers in a Chicago Tribune article in 1997, when they were both in their 70s:

"Would you believe that was one of the easiest things we ever did?" Harold told the paper.

"Did you know that we never even rehearsed that number?" added Fayard.

"When it came time to do that part, (choreographer) Nick Castle said: 'Just do it. Don`t rehearse it, just do it.' And so we did it—in one little take. And then he said: 'That's it—we can't do it any better than that.'"
