A major UCLA study says that at least 65 species of animals laugh

If you've never seen a fox giggle, you're in for a treat.

Foxes giggle like children on helium.

Laughter is one of the most natural impulses in humans. Most babies start to laugh out loud at around 3 to 4 months, far earlier than they are able to speak or walk. Expressing enjoyment or delight comes naturally to us, but we're not the only creatures who communicate with giggles.

Researchers at UCLA have identified 65 species of animals who make "play vocalizations," or what we would consider laughter. Some of those vocalizations were already well documented—we've known for a while that apes and rats laugh—but others may come as a surprise. Along with a long list of primate species, domestic cows and dogs, foxes, seals, mongooses and three bird species are prone to laughter as well. (Many bird species can mimic human laughter, but that's not the same as making their own play vocalizations.)

Primatologist and UCLA anthropology graduate student Sasha Winkler and UCLA professor of communication Greg Bryant shared their findings in an article in the journal Bioacoustics.



The authors explored various play vocalization sounds, recording them as noisy or tonal, loud or quiet, high- or low-pitched, short or long, a single call or rhythmic pattern.

But really, what we want to see is what animal laughter sounds like from various species, right? While the researchers said that it can be hard to document laughter in the wild, especially among animals with quieter vocalizations, we do have some examples captured on video.

Check out these foxes laughing like little kids:

Or maybe little kids on helium. How fun is that?

Ever seen a bonobo chimp laugh? Just as cute.

I'm not sure if tickling a baby bonobo is sweet or torturous, though these researchers surely know what they're doing. It's always delightful to see the instinctual playfulness of primates.

Laughter in some animals isn't as audibly apparent as it is in these foxes and chimps, though. Researchers from Humboldt University of Berlin found that rats laugh when they are tickled—and appear to enjoy tickling, as they seek it out—but their vocalizations are ultrasonic, so it's hard to hear them without special instruments.

The UCLA researchers shared that the study of laughter in animals can help us better understand our own evolutionary behavior.

“This work lays out nicely how a phenomenon once thought to be particularly human turns out to be closely tied to behavior shared with species separated from humans by tens of millions of years,” Bryant said, according to UCLA.

“When we laugh, we are often providing information to others that we are having fun and also inviting others to join,” Winkler said. “Some scholars have suggested that this kind of vocal behavior is shared across many animals who play, and as such, laughter is our human version of an evolutionarily old vocal play signal.”

Raise your hand if you just want to see a cow laughing for real now.

Making new friends as an adult is challenging. While people crave meaningful IRL connections, it can be hard to know where to find them. But thanks to one Facebook Group, meeting your new best friends is easier than ever.

Founded in 2018, NYC Brunch Squad brings together hundreds of people who come as strangers and leave as friends through its in-person events.

“Witnessing the transformative impact our community has on the lives of our members is truly remarkable. We provide the essential support and connections needed to thrive amid the city's chaos,” shares Liza Rubin, the group’s founder.

Despite its name, the group doesn’t just do brunch. They also have book clubs, seasonal parties, and picnics, among other activities.

NYC Brunch Squad curates up to 10 monthly events tailored to the specific interests of its members. Liza handles all the details, taking into account different budgets and event sizes – all people have to do is show up.

“We have members who met at our events and became friends and went on to embark on international journeys to celebrate birthdays together. We have had members get married with bridesmaids by their sides who were women they first connected with at our events. We’ve had members decide to live together and become roommates,” Liza says.

Members also bond over their passion for giving back to their community. The group has hosted many impact-driven events, including a “Picnic with Purpose” to create self-care packages for homeless shelters and recently participated in the #SquadSpreadsJoy challenge. Each day, the 100 members participating receive random acts of kindness to complete. They can also share their stories on the group page to earn extra points. The member with the most points at the end wins a free seat at the group's Friendsgiving event.

3,700-year-old Babylonian stone tablet gets translated, changes history

They were doing trigonometry 1500 years before the Greeks.

via UNSW

Dr. Daniel Mansfield and his team at the University of New South Wales in Australia have just made an incredible discovery. While studying a 3,700-year-old tablet from the ancient civilization of Babylon, they found evidence that the Babylonians were doing something astounding: trigonometry!

Most historians have credited the Greeks with creating the study of triangles' sides and angles, but this tablet presents indisputable evidence that the Babylonians were using the technique 1,500 years before the Greeks ever were.

Mom’s blistering rant on how men are responsible for all unwanted pregnancies is on the nose

“ALL unwanted pregnancies are caused by the irresponsible ejaculations of men. Period. Don't believe me? Let me walk you through it."

Mom has something to say... strongly say.

Members of The Church of Jesus Christ of Latter-day Saints, commonly known as Mormons, are a conservative group who aren't known for being vocal about sex.

But best selling author, blogger, and mother of six, Gabrielle Blair, has kicked that stereotype to the curb with a pointed thread on reducing unwanted pregnancies. And her sights are set directly at men.

Dad takes 7-week paternity leave after his second child is born and is stunned by the results

"These past seven weeks really opened up my eyes on how the household has actually ran, and 110% of that is because of my wife."

@ustheremingtons/TikTok

There's a lot to be gleaned from this.

Participating in paternity leave offers fathers so much more than an opportunity to bond with their new kids. It also allows them to help around the house and take on domestic responsibilities that many new mothers have to face alone…while also tending to a newborn.

All in all, it enables couples to handle the daunting new chapter as a team, making it less stressful on both parties. Or at least equally stressful on both parties. Democracy!

TikTok creator and dad Caleb Remington, from the popular account @ustheremingtons, confesses that for baby number one, he wasn’t able to take a “single day of paternity leave.”

This time around, for baby number two, Remington had the privilege of taking seven weeks off (to be clear—his employer offered four weeks, and he used an additional three weeks of PTO).

The time off changed Remington’s entire outlook on parenting, and his insights are something all parents could probably use.

Voice recordings of people who were enslaved offer incredible first-person accounts of U.S. history

"The results of these digitally enhanced recordings are arresting, almost unbelievable. The idea of hearing the voices of actual slaves from the plantations of the Old South is as powerful—as startling, really—as if you could hear Abraham Lincoln or Robert E. Lee speak." - Ted Koppel

Library of Congress

When we think about the era of American slavery, many of us tend to think of it as the far distant past. While slavery doesn't exist as a formal institution today, there are people living who knew formerly enslaved black Americans first-hand. In the wide arc of history, the legal enslavement of people on U.S. soil is a recent occurrence—so recent, in fact, that we have voice recordings of interviews with people who lived it.
