Scientists just created an enzyme that rapidly breaks down plastic pollution

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:

Ending Plastic Pollution with Designer Bacteriayoutu.be

Now researchers have revealed another game-changer in the plastic-eater—asuper-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.

10 anti-holiday recipes that prove the season can be tasty and healthy

Balance out heavy holiday eating with some lighter—but still delicious—fare.

Albertson's

Lighten your calorie load with some delicious, nutritious food between big holiday meals.

True

The holiday season has arrived with its cozy vibe, joyous celebrations and inevitable indulgences. From Thanksgiving feasts to Christmas cookie exchanges to Aunt Eva’s irresistible jelly donuts—not to mention leftover Halloween candy still lingering—fall and winter can feel like a non-stop gorge fest.

Total resistance is fairly futile—let’s be real—so it’s helpful to arm yourself with ways to mitigate the effects of eating-all-the-things around the holidays. Serving smaller amounts of rich, celebratory foods and focusing on slowly savoring the taste is one way. Another is to counteract those holiday calorie-bomb meals with some lighter fare in between.

Contrary to popular belief, eating “light” doesn’t have to be tasteless, boring or unsatisfying. And contrary to common practice, meals don’t have to fill an entire plate—especially when we’re trying to balance out heavy holiday eating.

It is possible to enjoy the bounties of the season while maintaining a healthy balance. Whether you prefer to eat low-carb or plant-based or gluten-free or everything under the sun, we’ve got you covered with these 10 easy, low-calorie meals from across the dietary spectrum.

Each of these recipes has less than 600 calories (most a lot less) per serving and can be made in less than 30 minutes. And Albertsons has made it easy to find O Organics® ingredients you can put right in your shopping cart to make prepping these meals even simpler.

Childhood stress shows up everywhere in adult life—even the inside of your mouth

According to a study from Iowa State University…our spit says it all.

how many wonders can this mouth cavern hold?

We know your relationship with your parents can affect a lot about who you are as you grow up. But is it possible that the good and bad of that relationship could actually show up in your saliva?

That's the bizarre-but-important question a team of researchers recently asked, the results of which were published in Developmental Science.

Kids in 1966 shared their predictions for the year 2000 and it's fascinating to see now

In many ways, the future turned out much brighter than these youngsters expected it to.

Thankfully, this girl's prediction was way off.

The idea of predicting the future has been the subject of countless books, movies and televisions shows (and is basically the basis of all gambling). Outside of a few uncanny instances, no one can tell exactly what the future holds, especially for the world at large. But people sure love to predict it anyway.

The BBC shared a video compilation of kids in 1966 sharing what they imagine the year 2000 would be like, and their predictions are fascinating. After five or six kids share, it becomes clear what some of the most pressing concerns of the 1960s were. Some kids thought we'd have bombed ourselves into oblivion. Others believed we'd be so overpopulated we would be packed like sardines and wouldn't be able to build houses anymore.

Not all of the predictions were so dark. Some kids had some hilarious predictions about cabbage pills and robots. Others thought we'd have better cures for diseases and less segregation among the races, which we have.

A study reveals the cheapest time to buy airfare

The average flyer misses the best deal by 15 days.

Taking a trip on the airline.

Everyone seems to have a theory on the best time to purchase airfare to save the most money. Some say it's right before take-off. Others will swear that prices are lowest six months before the flight. Well, now we have the truth. A scientific study was conducted by Expedia and the Airlines Reporting Commission that found the best times to buy flight tickets to get the best deal possible.

Some of what we used to think about gifted kids turned out to be wrong.


What can we learn from letting seventh graders take the SAT?

In the 1960s, psychologist Julian Stanley realized that if you took the best-testing seventh graders from around the country and gave them standard college entry exams, those kids would score, on average, about as well as the typical college-bound high school senior.

However, the seventh graders who scored as well or better than high schoolers, Stanley found, had off-the-charts aptitude in quantitative, logical, and spatial reasoning.
