When his species was on the brink, one tortoise got busy.

This is Diego. A very happy 100-year-old tortoise.

He's originally from the San Diego Zoo (hence the name) and was brought to the Galapagos Islands in the 1977. He's been living there ever since.

What's he so happy about? Well, how do I put this...

Diego has — almost single-handedly — revived his nearly extinct species in the Galapagos Islands.

Yeah, the old shelled stud has been pretty busy.

"He's a very sexually active male reproducer," said Washington Tapia, a tortoise preservation specialist at Galapagos National Park. "He's contributed enormously to repopulating the island."

Until very recently, Diego's species was in dire straits. For hundreds of years they were hunted for food by pirates and merchants, and before Diego's arrival in the islands, there were only 14 left.

Diego got to work, and it's estimated that he's fathered about 1,700 children so far.

"We did a genetic study and we discovered that he was the father of nearly 40 percent of the offspring released into the wild on Espanola," said Tapia.

Currently, he lives on Isla Santa Cruz with six females. And he'll likely live there for some time as his species can live well past 100.

Along with Diego's natural ... talents ... the revival of the Galapagos tortoise is thanks to some incredible work by conservationists around the world.

Organizations like the Galapagos Conservancy and the Charles Darwin Foundation have been hard at work for decades surveying, studying, and working to rescue endangered species on the Galapagos Islands.

It's an appropriate place to do so, too. After all, the Galapagos Islands are where Charles Darwin first took note of the incredible diversity of Earth's creatures and how their appearances varied based on where they live. That observation would eventually lead to his Theory of Natural Selection — which is one of the founding principles for how we understand life and evolution today.

As far as Diego...

You can call him "sex mad" or a "ladies' man" or even "the most interesting giant tortoise in the world."

I'm going to call him the name he really deserves. Hero.

He's a hero who had the courage, the pluck, the outright valor to do what was right and save his species. Sure it was hard, but did Diego complain? No. Did he crawl back into his shell and cower from the challenge before him? No.

Diego kept his chin up and walked right into the danger. Slowly. Because he's a tortoise.

Frankly, we should all be a little more like Diego. I mean ... not exactly like Diego. Just, you know, in spirit. The whole "facing challenges" thing.  

Way to go, old fella.

Dogs really do have favorite people, and here's how they decide who it will be

Sometimes their favorite people don't live in their house.

Dogs really do have favorite people. Here's how they decide

When my sister's dog, Junior, was on this side of the Rainbow Bridge, I was one of his favorite people. This dog would get full body wags every time I came around, and we'd spend most of the day cuddled up with each other. Now my dog, Cocolina, behaves in the same way whenever my sister comes to visit. But what goes into a dog deciding who their favorite person is? Spoiler, it's not always the person they live with.

Like humans, animals have their own personalities. You might rescue a dog thinking it will be the perfect companion, only to have the furry adoptee spend every waking moment following your partner around. You could spend hundreds of dollars on vet checkups, new harnesses, treats, and all the squeaky dog toys you can find, but that still won't be enough to convince a dog to love you. Instead of showering the giver of treats with kisses, they make goo-goo eyes at the pet sitter. It turns out they have their reasons.

Since our canine friends can't talk, we have to rely on the experts to explain what the deal is with how dogs pick their favorite human. Carol Erickson, a Pennsylvania SPCA animal advocate, gave a brief interview with CBS News Philadelphia to explain her take on how dogs determine their bestest, most favorite person.

"What it comes down to for all dogs is they decide their very favorite family member by who gives the most consistent, high-quality attention, play, and physical affection: ear rubs, scratches, that sort of thing. Dogs get positive associations from being around people who consistently provide positive experiences, including treats, meals, play that they enjoy, and remember also that early association in those first six months can influence who a dog may like better later on," she tells the outlet.

Rover backs up Erickson's claim that the first six months are crucial in determining who will become the dog's favorite person later in life. The website says, "Many dogs bond hardest to whoever cares for them during their key socialization period, which occurs between birth and six months." However, they later note that dogs can still be socialized appropriately even as adults.

The dog-sitting website also explains that it's not uncommon for people who are not the dog's primary caregiver to be their favorite person. Pointing out that physical affection is vital to dogs, if the mailman gives out head scratches daily but the owner doesn't, the mailman may become the dog's favorite person. While physical affection and treats go a long way for some pooches, those aren't the only things that get puppy eyes melting with love.

"While positive experiences play a big role, a dog’s favorite person isn’t always just the one holding the treat bag. Dogs also respond to emotional connection, tone of voice, and even body language. Their preferences are shaped by a mix of familiarity, trust, and how well a person understands their needs," explains Elle Vet Sciences. They later add, "Dogs also take emotional cues from us. If a person is stressed, loud, or inconsistent, a dog may be less likely to form a deep bond with them. On the other hand, someone who offers reassurance and stability often earns the title of 'favorite' without even realizing it."

In short, if you want to be your dog's bestie, being consistent with affection, actions, and even training and grooming will get you there a lot faster than treats alone. Dogs aren't trying to be persnickety; just like humans, they enjoy being around people who show them that they enjoy their company—and maybe some treats.

They thought their son lived a lonely life. But his funeral drew friends from around the globe.

Mats Steen touched far more people than his parents knew.

Netflix/YouTube

Mats Steen led a richer, fuller life than anyone new.

Tragically, Mats Steen was only 25 years old when he passed away, his body succumbing to the genetic disease that had slowly taken his mobility since childhood. He'd lived in a wheelchair since his early teens, and by his 20s, his physical abilities had deteriorated to the point of only being able to move his fingers. He could push buttons and use a mouse, and he spent nearly all of his waking hours playing video games in his parents' basement.

His family loved him and cared for him through it all, giving him as much of a normal life as they could. But they also lamented everything they knew he'd missed out on. "Our deepest sorrow lay in the fact that he would never experience friendships, love, or to make a difference in people's lives," Mats' father shares.

Mats left behind the password to a blog he kept. Not knowing if anyone would actually read it, his parents published the news of Mats' passing in a blog post, adding their email address in case anyone wanted to reach out.

Much to their surprise, messages began pouring in from around the world—not just with condolences, but with heartfelt stories from people who called Mats their friend.

The Steens soon discovered that their son had lived a much fuller life than they'd ever imagined—one that included all the things they always wished for him.

As his online life was revealed, the family learned that Mats began his days with a routine 30-minute sprint through the forest. He frequented cafes and pubs, chatting with strangers and flirting with women. He sat by campfires having heart-to-heart conversations. He made friends and enemies. He fought heroic battles. He supported people in times of need. He gave advice that people took. He experienced his first kiss.

And he did it all as "Ibelin," his handsome, muscular avatar in the online game World of Warcraft.

- YouTube youtu.be

Mats' life is showcased in the documentary The Remarkable Life of Ibelin, in which his parents share the story of how they discovered their son's group of friends they didn't know he had.

People who've never played an open world roleplay game like World of Warcraft may wonder how real community can be built through it, but Mats' story proves it's possible. The friends he made through the game have shared the real influence he'd had on their real lives, from helping them with problems they were facing to empowering them to make positive changes in their relationships.

Though he never met them face-to-face, Mats' online friends say he made a significant impact on them.

A young woman Ibelin had connected with as a teenager—the one with whom he'd shared that first virtual kiss—shared that her parents had taken away her computer when they feared gaming was interfering with her studies. When she logged on at a local library, Mats gave her a letter he had written to give to her parents, encouraging them to talk with her about her gaming hobby and to work out a solution together that didn't require her to give it up completely. She printed it and gave it to them. Miraculously, it worked.

Another woman had been having a hard time connecting with her autistic son as a young adult. When she talked with Ibelin about her struggles, he suggested that she and her son start gaming together and connect in that way first. Eventually, that connection via the virtual world led to warmer in-person interactions between them—and a life-changing shift in their relationship.

"I don't think he was aware of the impact that he had done to a lot of people," the mother shared.

Mats interacted with the same online friends as Ibelin for years, going through the kinds of ups and downs all friendships experience. He kept his physical condition a secret until close to the end of his life, when he finally opened up to another player who convinced him to share his reality with the others. Some traveled from other countries to attend his funeral, with one of them speaking on the group's behalf and a few of them serving as pallbearers. Those who knew Ibelin also held a memorial in-game at his virtual gravesite—a tradition that has spread beyond just his own guild.

Typically, we think of someone escaping the real world and spending hours a day playing video games as unhealthy, but for Mats, it was a lifeline. As Ibelin, Mats was able to have a level of independence and a rich social life that simply wasn't possible for him in the offline world—an uniquely modern phenomenon that technology and human creativity have made possible.

Mats' impact on his online community was real, and 10 years after his passing his impact is spreading even further.

Duchenne muscular dystrophy (DMD), the genetic disease that Mats lived with and ultimately died from, affects 300,000 boys worldwide. It only affects males and it has no cure. But CureDuchenne, a global nonprofit dedicated to funding and finding a cure, partnered with video game company Blizzard Entertainment's World of Warcraft in Mats' honor from the end of 2024 until January 7, 2025. During that window, World of Warcraft players could purchase a limited-edition pet fox named Reven ("fox" in Norwegian). The Reven Pack, which includes a transmog backpack and Reven’s Comfy Carrier, costs $20, with 100% of the purchase price being donated to CureDuchenne.

“Mats Steen lived a life in World of Warcraft that he couldn’t in the real world as he fought Duchenne muscular dystrophy alongside his incredible family, who I’m proud to have met and fallen in love with,” said Holly Longdale, executive producer of World of Warcraft. “Working with CureDuchenne for our Charity Pet Program, in honor of Mats’ memory, allows us to harness the power of our phenomenal global community to bring meaningful impact to so many lives.”

In February 2025, CureDuchenne announced that The Reven Pack raised over two million dollars in support. Later in the month, Debra and Hawken Miller of Cure Duchenne spoke with ViceVice and shared how The Reven Pack helped raise valuable awareness about Duchenne in addition to funds. For those interested in updates, the site keeps donors and supporters current on all developments in Duchenne research news.

Mats life was truly impactful in many ways and to many people. His love, kindness, and friendship touched lives and his legacy continues to help those struggling with this rare disease. According to the site, since the inception of CureDuchenne, life expectancy for those with the disease has increased by a decade and over fifty million dollars have been raised for research, education, and care.

You can learn more about Mats' story in the award-winning documentary, The Remarkable Life of Ibelin on Netflix.

6th grader's science fair project answers age-old question: 'Do cat buttholes touch everything?'

You know you've been wondering.

Do cat buttholes touch every surface they sit on? Science answers.

Cat owners are a special breed of people. Sometimes, in dealing with feline friends, they have unique questions that even Google doesn't always have the answer to. This is probably the sole reason cat forums exist, but one kid who needed a 6th grade science project decided to skip the cat forums for answers and instead use the scientific method. Kaeden Henry, a sixth grader living in Florida, bravely pondered a question few (if any one) has been brave enough to ask: do cat buttholes touch every surface they sit on?

Since cats do whatever the heck they want, training them not to jump on kitchen counters is a feat even Hercules struggles to complete. These fierce felines don't care if you're cooking dinner or trying to get comfy in bed. If they want to sit somewhere, they're going to do it. The thought of cat butts on that expensive Serta pillow designed to feel like you're sleeping on a cloud can gross people out, but thanks to Kaeden, you no longer have to wonder if the butthole itself is also making contact.

The curious sixth grader is homeschooled and well-versed in the scientific method thanks to her mother's PhD in animal behavior with a concentration in feline behavior. And, since they own cats, the science experiment was pretty straightforward (and directly impactful).

To complete the experiment, Henry and his mom, Kerry Hyde, bought non-toxic lipstick and applied it to each of their cat's anuses. Then, the cats were given commands. (Commands... hilarious, right?)

"Non-toxic lipstick was applied to their bum-bums, they were then given a series of commands (sit, wait, lie down, and jump up. Side note: Both cats have been trained since kittenhood with a variety of commands, they also know how to high-five, spin around, and speak.), they were compensated with lots of praise, pets, and their favorite treats, and the lipstick was removed with a baby wipe once we collected our data in just under 10 minutes," Hyde wrote in a Facebook post.

The results? Turns out that, no, cat buttholes do not touch every surface cats sit on.

Now, let's all take a collective sigh of relief while we go over the details. Kaeden's experiment covered long-haired, short-haired, and medium-haired cats (if your cat is hairless, you better stock up on Clorox wipes just in case).



"His results and general findings: Long and medium haired cat’s buttholes made NO contact with soft or hard surfaces at all. Short haired cats made NO contact on hard surfaces. But we did see evidence of a slight smear on the soft bedding surface. Conclusion, if you have a short haired cat and they may be lying on a pile of laundry, an unmade bed, or other soft uneven surface, then their butthole MAY touch those surfaces!" Hyde shares.

Now every curious cat owner can rest easy knowing that as long as their cat has hair, their bare bottom balloon knot is not touching the majority of surfaces in their home.

The amusing experiment caught the Internet's attention. People laughed and commented, with one person writing, "This is probably the most useful information I’ve learned from a science fair project."

"Good to know!...I can now eat my sandwich left on the counter with confidence!" another writes.

"A+++!!! Whew!! I am very grateful for your sciencing on this subject. My fears from walking in on my cat sitting on my laptop keyboard and subsequently being grossed out and cleaning furiously in a hyper-ocd manner have been somewhat allayed and now maybe I won’t have to use QUIIITE so many wipes." someone chimes in.

"Finally.. Someone answers the important questions!!"

The best part of the story? Kaeden's mom has a Ph.D. in animal behavior, specializing in feline behavior, and even she learned something new. The power of science!

Jane Goodall leaves behind hope and a survival guide to get through trying times

She offered four solid reasons to stay hopeful.

Jane Goodall leaves behind hope and survival guide for trying times

Jane Goodall was a wildlife conservationist, zoologist, and anthropologist. Her incredible career spanned multiple decades, resulting in the scientific community and animal lovers alike having a deeper, more thorough understanding of chimpanzees. The conservationist is most famous for living amongst the Gombe National Park (previously Gombe Stream Game Reserve) in Tanzania.

The anthropologist's approach to wildlife conservation was solidified when she founded the Jane Goodall Institute, where she expanded her work to include global advocacy "for human rights, animal welfare, species and environmental protection, and many other crucial issues," according to the institute's website. In their long tribute to Dr. Goodall, the institute reveals that the scientist dreamed about writing books about her work with animals since she was a child. A dream that came true, as the now late conservationist authored over 25 books.

Goodall passed away from natural causes in October 2025 while on a speaking tour. She was 91 years old and still extremely involved in the work that has defined her life. While the humanist wrote books for children and adults, her final book, written in 2021 with Douglas Abrams and Gail Hudson, was left behind as a reminder of hope in hard times. The Book of Hope: A Survival Guide for Trying Times just might be one of the most treasured gifts one human can leave for humanity. It's fitting that Goodall helped author it.

Within the pages of the book, Goodall lists four reasons for hope: human intellect, the resilience of nature, the power of young people, and the indomitable human spirit. In the book, Goodall drives home the point that even in the most trying times, hope isn't something that happens blindly.

“Hope is often misunderstood. People tend to think that it is simply passive wishful thinking: I hope something will happen but I’m not going to do anything about it. This is indeed the opposite of real hope, which requires action and engagement,” she says.

In response to the back-and-forth dialogue between Goodall and Abrams in the book, Abrams explains the zoologist's approach to hope by adding, "She says that people who wonder how you can have hope in seemingly hopeless situations, like a death camp, confuse hope with idealism. Idealism expects everything to be fair or easy or good. She says it's a defense mechanism not unlike denial or delusion. Hope, she says, does not deny the evil but is a response to it. I was beginning to see that hope was not just wishful thinking. It did take the facts and the obstacles into account, but it did not let them overwhelm or stop us. Certainly, this was true in many seemingly hopeless situations.”

Hope is a theme throughout a lot of Goodall's writings and interviews. When speaking to Democracy Now in 2016, she was asked how one person can make a difference, and her response may help others who feel as if they've been working towards change without reward or results.

"Well, the thing is, it's not about one person. Can they make a difference? Everybody, every day, does make a difference. And if we think about the consequences of the choices we make, what we buy, what we eat, what we wear, and we start making the right ethical choices, then when that's multiplied by a thousand, a million, a billion, several billion times, and we see the world moving towards change. So the most important thing is to give people hope."

People share words they inexplicably love, and it's a beautiful way to boost your vocabulary

Some words are simply pure joy to say, like onomatopoeia.

People share their absolute favorite words.

Without words, communicating with each other would be a lot more difficult. According to Merriam Webster, there are estimated to be about one million words in the English language (although there is no official count).

Some words are simply pure joy to say, like onomatopoeia—words that are a vocal imitation of the sound they are associated with it, such as "buzz" or "hiss." While other words hold special meaning or a silly backstory, some words can make you physically cringe.

Over on Reddit, linguistics lovers and grammar enthusiasts created a rich conversation delving into words that just hit. Here are 43 words that they absolutely adore:

- YouTube www.youtube.com

"Everybody has a favorite word. I have 2. Falafel & wicker. Just because they're fun to say." - AngelicDaemon420

"Onomatopoeia because of it's cadence and the idea of a word sounding like the thing it describes. It's like poetry in my ears." - MuckleRucker3

"I could never pick just one. There's like a top 10 or top 20. Some of them are starling, decanted, apoplectic, crestfallen, hubris." - rgtgd

"Scallywag and crocodilian are two of my favorite words. Also, the name Talleyrand is also great." - Hoppy_Croaklightly

"Cahoots." - looking4truffle

"When I was a teenager, my favorite word was spaghettification (what they believe happens inside a black hole). Now I lean towards onomatopoeia." - illizzilly

"Murmuration and defenestrate, for both the way they sound and their meanings." - jeekle

"Plethora. It means a lot to me." - Fosad

"Entendre, it just flows nicely. Also a fan of juxtaposition for the same reasons. No meaning, simply phonetic." - duh_nom_yar

"Tomfoolery. It's just so old-timey, as in 'what manner of tomfoolery is this?' And it has never become trendy again..." - AuNaturellee

"Skedaddle makes me laugh when I say it. Schadenfreude.... I love German words." - Royal_Ad_6026

Tintinnabulation was a word I had never seen before. And since back in the dark ages we had to read aloud in class and memorize poems this word fascinated me. I fell in love with poetry because of this word." - ReadNapRepeat
