A juice company dumped orange peels in a national park. Here's what it looks like now.

12,000 tons of food waste and 21 years later, this forest looks totally different.

A juice company dumped orange peels in a national park. Here's what it looks like now.


In 1997, ecologists Daniel Janzen and Winnie Hallwachs approached an orange juice company in Costa Rica with an off-the-wall idea.

In exchange for donating a portion of unspoiled, forested land to the Área de Conservación Guanacaste — a nature preserve in the country's northwest — the park would allow the company to dump its discarded orange peels and pulp, free of charge, in a heavily grazed, largely deforested area nearby.

One year later, one thousand trucks poured into the national park, offloading over 12,000 metric tons of sticky, mealy, orange compost onto the worn-out plot.



The site was left untouched and largely unexamined for over a decade. A sign was placed to ensure future researchers could locate and study it.

16 years later, Janzen dispatched graduate student Timothy Treuer to look for the site where the food waste was dumped.

Treuer initially set out to locate the large placard that marked the plot — and failed.

"It's a huge sign, bright yellow lettering. We should have been able to see it," Treuer says. After wandering around for half an hour with no luck, he consulted Janzen, who gave him more detailed instructions on how to find the plot.

When he returned a week later and confirmed he was in the right place, Treuer was floored. Compared to the adjacent barren former pastureland, the site of the food waste deposit was "like night and day."

"It was just hard to believe that the only difference between the two areas was a bunch of orange peels. They look like completely different ecosystems," he explains.

The area was so thick with vegetation he still could not find the sign.

Treuer and a team of researchers from Princeton University studied the site over the course of the following three years.

The results, published in the journal "Restoration Ecology," highlight just how completely the discarded fruit parts assisted the area's turnaround.

The ecologists measured various qualities of the site against an area of former pastureland immediately across the access road used to dump the orange peels two decades prior. Compared to the adjacent plot, which was dominated by a single species of tree, the site of the orange peel deposit featured two dozen species of vegetation, most thriving.

In addition to greater biodiversity, richer soil, and a better-developed canopy, researchers discovered a tayra (a dog-sized weasel) and a giant fig tree three feet in diameter, on the plot.

"You could have had 20 people climbing in that tree at once and it would have supported the weight no problem," says Jon Choi, co-author of the paper, who conducted much of the soil analysis. "That thing was massive."

Recent evidence suggests that secondary tropical forests — those that grow after the original inhabitants are torn down — are essential to helping slow climate change.

In a 2016 study published in Nature, researchers found that such forests absorb and store atmospheric carbon at roughly 11 times the rate of old-growth forests.

Treuer believes better management of discarded produce — like orange peels — could be key to helping these forests regrow.

In many parts of the world, rates of deforestation are increasing dramatically, sapping local soil of much-needed nutrients and, with them, the ability of ecosystems to restore themselves.

Meanwhile, much of the world is awash in nutrient-rich food waste. In the United States, up to half of all produce in the United States is discarded. Most currently ends up in landfills.

"We don't want companies to go out there will-nilly just dumping their waste all over the place, but if it's scientifically driven and restorationists are involved in addition to companies, this is something I think has really high potential," Treuer says.

The next step, he believes, is to examine whether other ecosystems — dry forests, cloud forests, tropical savannas — react the same way to similar deposits.

Two years after his initial survey, Treuer returned to once again try to locate the sign marking the site.

Since his first scouting mission in 2013, Treuer had visited the plot more than 15 times. Choi had visited more than 50. Neither had spotted the original sign.

In 2015, when Treuer, with the help of the paper's senior author, David Wilcove, and Princeton Professor Rob Pringle, finally found it under a thicket of vines, the scope of the area's transformation became truly clear.

"It's a big honking sign," Choi emphasizes.

19 years of waiting with crossed fingers had buried it, thanks to two scientists, a flash of inspiration, and the rind of an unassuming fruit.

Dentist explains the 3 times you should never brush your teeth

Sometimes not brushing your teeth is the best way to protect them.

Add this to the list of things you didn't learn in health class.

For those who love the oh-so fresh feeling of immediately running to brush their teeth after a meal, we got some bad news.

London-based dental surgeon and facial aesthetics practitioner Dr. Shaadi Manouchehri recently shocked around 12 million viewers on TikTok after sharing the three occasions when you should “never” be scrubbing those pearly whites—if you want to actually protect your teeth, that is.

The hardest part about this video, which some viewers are undoubtedly still processing, is that each of these no-no times is exactly when brushing your teeth is the only thing you’ll want to do. So much for instincts.


Number one on Manouchehri’s list, which caused the most controversy in the comments, isright after vomiting. Yep, you read that right.

“This is because the contents of the stomach are extremely acidic and the mouth is already in a very acidic state so if you brush straight after [vomiting] you’re basically wearing away your enamel,” Manouchehri explained.

Of course, commenters weren’t willing to let this one go without a fight. One viewer wrote, “I would rather lose all of my teeth than not brush after vomiting.”

Manouchehri also says to avoid brushing your teeth directly after eating breakfast. This is because “when you’ve just eaten, the mouth is, again in a “very acidic state,” so if you’re brushing your teeth you’re rubbing that acid on the tooth, which wears down the enamel.” Other sources have also confirmed that brushing your teeth tight after any meal isn’t really recommended.

This goes double for right after sweets. Manouchehri says to wait a full 60 minutes before putting a toothbrush anywhere near your mouth after having something sugary. Because…you guessed it…acid.

Does this advice seem counterintuitive? Don’t worry, you’re not alone.

“Ah, yes, the three times I want to brush my teeth more than any other time,” one person joked.

Luckily, there are few alternatives to try if you want that good, clean mouth feeling but don’t want to compromise your enamel—the simplest being to either rinse with or drink water. You can also use sugar-free chewing gum or conclude your meal with dairy or non-acidic foods, according to Advanced Dental Associates. If you still crave a little more of a hygiene bang, you can opt for a mouthwash with fluoride and using a tongue cleaner, which removes excess acid, per Curetoday.com.

Guess there’s a time and a place for everything, even when it comes to dental hygiene.

There's no way they didn't understand what she was saying.

Okay, so maybe dogs don’t understand everything we tell them exactly as a human would. But is that gonna stop us from having full blown conversations with them? Of course not. And the times they do seem to comprehend what’s being communicated—pure comedy.

Take this dog mom’s hilarious pre-grooming pep talk with Shih-Tzus Branston, Pickle and Gizmo. She minced no words telling them exactly how this trip was gonna go. And the message seemed to be received.

Branston (the troublemaker, apparently) got a firm warning of what not to do, including telling white lies about his upbringing.

“I don’t need you running in telling the first dog you see that this is what this is what your hair used to look like when you lived in the Bronx running up and down the block, cause I know for a fact, Branston, that you live in a rural village,” she tells him.

Viewers, however, seemed on board with Branston’s Bronx-affiliation, even if it was a little white lie. One person joked, “don’t be mad at the treats that I got, I’m still Branny from the block.”

In the video, Branston is also instructed to not tell everyone that he “identifies as a BUll Mastiff,” which gets the most adorable look of disappointment for wee little Branston.

As for Gizmo and Pickle—mom’s best advice is to pretend like they don’t know Branston.

Perhaps the best part is mom’s British accent, which makes the entire clip feel like something pulled straight outta “Ted Lasso.” That, or the complete shock the Shih-tzu trio has at being informed of their weight class.

Watch:

@branstonandpickle01 Your NOT from the Bronx and you never ran up and down the block!! #dogsoftiktok #peptalktoyourdog #branstonwehavearrived #shihtzusoftiktok #peptalkbranston #funnydogvideos #funnyvideos #nyc #bronx #funny #dogs #dogtok ♬ original sound - Branston,Pickle&Gizmo

Perhaps Branston, Pickle, and Gizmo’s mom isn’t totally off-base by giving them a talking to. According to the website allshihtzu.com, this breed had a “unique intelligence,” which gets best demonstrated by their attuned, empathic connection to their human families. Meaning that while they might not have the same kind of smarts as border collies or other herding dogs, their super power is picking up social cues.

And, again, even if they had no earthly idea what their mom was saying, odds are she’d still be talking to them anyway. Why? Because pets are our babies. And baby talk is fun.jk

A sad-looking Labrador Retriever

The sweet-faced, loveable Labrador Retriever is no longer America’s favorite dog breed. The breed best known for having a heart of gold has been replaced by the smaller, more urban-friendly French Bulldog.

According to the American Kennel Club, for the past 31 years, the Labrador Retriever was America’s favorite dog, but it was eclipsed in 2022 by the Frenchie. The rankings are based on nearly 716,500 dogs newly registered in 2022, of which about 1 in 7 were Frenchies. Around 108,000 French Bulldogs were recorded in the U.S. in 2022, surpassing Labrador Retrievers by over 21,000.


The French Bulldog’s popularity has grown exponentially over the past decade. They were the #14 most popular breed in 2012, and since then, registrations have gone up 1,000%, bringing them to the top of the breed popularity rankings.

The AKC says that the American Hairless Terrier, Gordon Setter, Italian Greyhound and Anatolian Shepherd Dog also grew in popularity between 2021 and 2022.

The French Bulldog was famous among America’s upper class around the turn of the 20th century but then fell out of favor. Their resurgence is partly based on several celebrities who have gone public with their Frenchie love. Leonardo DiCaprio, Megan Thee Stallion, Alexandra Ocasio-Cortez, Reese Witherspoon and Lady Gaga all own French Bulldogs.

The breed earned a lot of attention as show dogs last year when a Frenchie named Winston took second place at the Westminster Kennel Club Dog Show and first in the National Dog Show.

The breed made national news in early 2021 when Gaga’s dog walker was shot in the chest while walking two of her Frenchies in a dog heist. He recovered from his injuries, and the dogs were later returned.

They’ve also become popular because of their unique look and personalities.

“They’re comical, friendly, loving little dogs,” French Bull Dog Club of America spokesperson Patty Sosa told the AP. She said they are city-friendly with modest grooming needs and “they offer a lot in a small package.”

They are also popular with people who live in apartments. According to the AKC, Frenchies don’t bark much and do not require a lot of outdoor exercise.

The French Bulldog stands out among other breeds because it looks like a miniature bulldog but has large, expressive bat-like ears that are its trademark feature. However, their popularity isn’t without controversy. “French bulldogs can be a polarizing topic,” veterinarian Dr. Carrie Stefaniak told the AP.

French Bulldogs have been bred to have abnormally large heads, which means that large litters usually need to be delivered by C-section, an expensive procedure that can be dangerous for the mother. They are also prone to multiple health problems, including skin, ear, and eye infections. Their flat face means they often suffer from respiratory problems and heat intolerance.

Frenchies are also more prone to spine deformations and nerve pain as they age.

Here are the AKC’s top ten most popular dog breeds for 2022.

1 French Bulldogs

2 Labrador Retrievers

3 Golden Retrievers

4 German Shepherd Dogs

5 Poodles

6 Bulldogs

7 Rottweilers

8 Beagles

9 Dachshunds

10 German Shorthaired Pointers

What is Depression?

In the United States, close to 10% of the population has depression, but sometimes it can take a long time for someone to even understand that they have it.

One difficulty in diagnosis is trying to distinguish between feeling down and experiencing clinical depression. This TED-Ed video from December 2015 can help make the distinction. With simple animation, the video explains how clinical depression lasts longer than two weeks with a range of symptoms that can include changes in appetite, poor concentration, restlessness, sleep disorders (either too much or too little), and suicidal ideation. The video briefly discusses the neuroscience behind the illness, outlines treatments, and offers advice on how you can help a friend or loved one who may have depression.


Unlike the many pharmaceutical ads out there with their cute mascots and vague symptoms, the video uses animation to provide clarity about the mental disorder. It's similar in its poignant simplicity to the HBO short documentary "My Depression," based on Liz Swados' book of the same name.

New baby and a happy dad.


When San Francisco photographer Lisa Robinson was about to have her second child, she was both excited and nervous.

Sure, those are the feelings most moms-to-be experience before giving birth, but Lisa's nerves were tied to something different.

She and her husband already had a 9-year-old son but desperately wanted another baby. They spent years trying to get pregnant again, but after countless failed attempts and two miscarriages, they decided to stop trying.


Of course, that's when Lisa ended up becoming pregnant with her daughter, Anora. Since it was such a miraculous pregnancy, Lisa wanted to do something special to commemorate her daughter's birth.

So she turned to her craft — photography — as a way to both commemorate the special day, and keep herself calm and focused throughout the birthing process.

Normally, Lisa takes portraits and does wedding photography, so she knew the logistics of being her own birth photographer would be a somewhat precarious new adventure — to say the least.

She initially suggested the idea to her husband Alec as a joke.

"After some thought," she says, "I figured I would try it out and that it could capture some amazing memories for us and our daughter."

In the end, she says, Alec was supportive and thought it would be great if she could pull it off. Her doctors and nurses were all for Lisa taking pictures, too, especially because it really seemed to help her manage the pain and stress.

In the hospital, she realized it was a lot harder to hold her camera steady than she initially thought it would be.

"Eventually when it was time to push and I was able to take the photos as I was pushing, I focused on my daughter and my husband and not so much the camera," she says.

"I didn't know if I was in focus or capturing everything but it was amazing to do.”

The shots she ended up getting speak for themselves:

"Everybody was supportive and kind of surprised that I was able to capture things throughout. I even remember laughing along with them at one point as I was pushing," Lisa recalled.

In the end, Lisa was so glad she went through with her experiment. She got incredible pictures — and it actually did make her labor easier.

Would she recommend every mom-to-be document their birth in this way? Absolutely not. What works for one person may not work at all for another.

However, if you do have a hobby that relaxes you, figuring out how to incorporate it into one of the most stressful moments in your life is a pretty good way to keep yourself calm and focused.

Expecting and love the idea of documenting your own birthing process?

Take some advice from Lisa: "Don't put pressure on yourself to get 'the shot'" she says, "and enjoy the moment as much as you can.”

Lisa's mom took this last one.
