Last year, we shared the sad impact that plastic pollution has had on some of our planet's most beautiful places. With recycling not turning out to be the savior it was made out to be, solutions to our growing plastic problem can seem distant and complex.

We have seen some glimmers of hope from both human innovation and nature itself, however. In 2016, a bacteria that evolved with the ability to break down plastic was discovered in a Japanese waste site. Two years later, scientists managed to engineer the mutant plastic-eating enzyme they called PETase—named for polyethylene terephthalate, the most common plastic found in bottles and food packaging—in a lab.

Here's an explainer of how those enzymes work:

Now researchers have revealed another game-changer in the plastic-eater—a super-enzyme that can break down plastic six times faster than PETase alone.


The super-enzyme is a bit of a frankenzyme, created by linking different enzymes together. "When we linked the enzymes, rather unexpectedly, we got a dramatic increase in activity," Prof John McGeehan, at the University of Portsmouth, UK, told The Guardian. "This is a trajectory towards trying to make faster enzymes that are more industrially relevant. But it's also one of those stories about learning from nature, and then bringing it into the lab."

This new research has been published in the journal Proceedings of the National Academy of Sciences.

Combining enzymes could be the key to making various kinds of plastics and combined materials fully recyclable. "There's huge potential," said McGeehan. "We've got several hundred in the lab that we're currently sticking together."

For example, combining the plastic-eating enzymes with existing enzymes that break down natural fibers could allow fabrics made of mixed materials to be recycled, McGeehan told The Guardian. "Mixed fabrics [of polyester and cotton] are really tricky to recycle. We've been speaking to some of the big fashion companies that produce these textiles, because they're really struggling at the moment."

This newest research isn't the first to improve upon the plastic-eating bacteria discovery. In April, a French chemistry company called Carbios shared their own mutant enzyme that can degrade 90% of plastic bottles within 10 hours. However, that enzyme, which originally discovered in a pile of composting leaves, requires heating above 70 degrees Celsius (nearly 160 degrees Fahrenheit), whereas this new super-enzyme works at room temperature.

Not that it's a cutthroat competition. We are talking about helping out the entire planet and saving life as we know it, after all. McGeehan suggested that the researchers work together with the private sector to get the enzymes working out in the real world. "If we can make better, faster enzymes by linking them together and provide them to companies like Carbios, and work in partnership, we could start doing this within the next year or two," McGeehan told The Guardian.

McGeehan did emphasize to CNN that the super-enzyme is "still way too slow" to be commercially viable at this point, but it is a huge step in the process. "We were actually quite surprised it worked so well," he told CNN.

Here's to science coming up with solutions to the problems human scientific advances have created, and here's to learning to live in better balance with nature in the process.

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.

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.

When Donato Di Camillo was a kid, his family couldn't afford film for their Polaroid camera.

So instead, he ran around the house with a film-less camera pretending to be a hotshot photographer on an African safari, mimicking the heroes behind iconic photos he saw in the discarded National Geographic magazines his dad grabbed for him out of the garbage.

Years later, when Di Camillo found himself in prison after collecting a lengthy rap sheet of thefts, he discovered a library full of those same magazines.

While other inmates were working out or getting into trouble, he pored over old issues of National Geographic, Life, and Time.

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.'"
