Whales used to be land predators? Fascinating video explains how they're related to wolves.

But not all mysteries are solved.

Did seals get lost in the mix?

I think it’s pretty safe to say that when it comes to evolution, most people typically picture aquatic life forms sprouting legs then coming onto land … not the other way around.

Shockingly enough, a creature almost synonymous with the sea didn’t actually begin that way. And boy, is it a whale of a tale.

A mind-blowing video recently posted by PBS Eons reveals that whales were actually predatory land animals … the same ones that would later become wolves, specifically.

Yep, you read that right. Land animals. With arms and legs and everything.

To explain, we’ll need to go back 52 million years.

Before the warm and rainy Eocene epoch—the same time period that brought us the first horses and bats—whales looked more like the image below.

Something like a mix between a wolf and crocodile, if you ask me.

You know it's hotter under the water.

Yes, animals did move from the sea to the land, bringing us the first mammals. But then, over time, some mammals were like, "nah, it's that ocean life for me." Including some of these fellas.

These creatures first went into the water during the Eocene time period and eventually traded in their arms to become “sleeker and more streamlined,” while still holding onto their teeth.

By now they look less like a wolf and more like a murderous dolphin.

whale evolution, whale science

You're welcome for the nightmare fuel.

Cut to roughly 34-36 million years ago, and the species have diversified into the two major whale groups we see today: the Odontoceti (or “toothed whales”), which include sperm whales, orcas and dolphins, and the Mysticeti, better known as baleen whales … you know, those big guys with the filter-like “teeth” (aka baleen) that eat loads and loads of plankton?

The baleen whale’s evolution in particular has scientists a bit baffled, as there is no definitive evidence as to how, when or even why they began filter feeding in the first place. In fact, the first fossil of a mysticetes appeared around 36 million years ago, but baleen doesn’t show up until later, around 11 million years ago. Even the baleen’s oldest ancestor, the Mystacadon, according to the PBS video, showed no signs of baleen when researchers discovered it in 2019.

One theory: The cooled ocean current of the Oligocene epoch brought about an abundance of nutrients—specifically plankton—which made it more advantageous to bulk feed rather than hunt for single prey. This also helps explain the giant boom in different whale species.

Still, it’s all up for debate, and likely will be for a while since ancient baleen is hard to come by. Baleen, unlike teeth, is made of keratin, the same biodegradable substance hair and nails are made out of and, therefore, doesn’t fossilize well.

As the host cleverly quipped, “It’s basically like a big mustache inside the whale's mouth.”

Bottom line: We know a lot about nature, but there is still so much to learn.

If you’d like to find out more—like how the Mystacadon ate its prey by doing a super weird thing called suction feeding—you can check out the full video here:

6th grader's science experiment answers, 'Do cat buttholes touch every surface they sit on?'

A question no one knew they needed answered.

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

Cat owners sometimes 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.

"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!!"

Researchers hacked 5 people's brains so they could see a new and impossible color

The new color 'olo' is neat, but the technique behind it could be groundbreaking.

Only five people in the world have seen the mysterious color "Olo"

Color is one of the great joys of being alive. The brilliant blue sky, the green grass, the exotic pinks and purples and teals in coral or tropical fish. Soaking it all in is truly a feast for the eyes, and some studies even show that certain colors can trigger specific emotions in people. Orange may evoke feelings of joy, and red may conjure feelings of love, while blue may have a calming effect.

One of the most interesting things about colors, though, is that they are finite. Though the world is full of undiscovered plants, creatures, and even elements, the entire color spectrum is known and documented. Due to the nature of light in our universe and how it reflects off of physical objects, all perceived color must be created by some combination of the primary colors (blue, green, and red — yes, green, not yellow!). There are essentially unlimited combinations, but they all exist on a known spectrum — different hues and shades of pink or emerald or orange.

However, a team of researchers recently decided to push the limits of human perception. They "hacked" participants' retinas to allow them to see an impossible color.

color, green, blue, color wheel, physics, light, wavelengths, science The paint companies are dying to know the secret formula for the new color.Giphy

Scientists from the University of California, Berkeley, developed a new technique called "Oz," which would allow them to activate specific cones in the retina. Cones are light-sensitive cells that respond to different wavelengths of light. When the three types of cones are activated in different ways, our brains perceive colors.

One fascinating bit of background is that the "M" cone, which typically responds strongest to green (Medium wavelength), can not naturally be activated without also activating the Long and Short cones. So even the purest green on the planet would also, to a smaller degree, stimulate the parts of our eyes that are mostly correlated with red and blue.

The team wanted to find out what would happen if they could isolate and activate only the M, or green, cone using the new technique.

The result? The five participants reported seeing an absolutely unreal, brilliant shade of green like nothing they had ever experienced. Imagine a bright green laser cranked up to the highest saturation and brilliance possible, the purest and brightest green your brain could possibly comprehend. Participants noted that a bright green laser pointed looked "pale" in comparison to the new color.

The name of the new, impossible color? Olo, or 010 (indicated zero stimulation of the L and S cones and full stimulation of the M cones).

It's fair to wonder, if olo is impossible and can never naturally exist without manual stimulation of the retinal cones, what's the point of the experiment?

The introduction of a "new color" is certainly interesting and makes for a good headline, but the real value of this study lies in the future applications of the Oz technique.

The research team hopes that the detailed retinal maps they have developed, along with their ability to stimulate specific rods and cones in the eye in any combination, will enable major breakthroughs in the study and treatment of various visual impairments.

For example, Oz could one day cure color blindness or unlock new treatments for cataracts or glaucoma. It could even play a role down the line in curing certain types of blindness. Isn't it wild how our understanding of how our eyes perceive color tells us so much?

But those days are a long way off, for now. In the meantime, only five people in the world have experienced the brilliance of olo, and the rest of us will just have to imagine it.

Yet another school district shifts to 4-day week and parents are sounding off

So... when are we getting the matching 4-day work week?

Unsplash

When talking with other parents I know, it's hard not to sound like a grumpy old man when we get around to discussing school schedules. "Am I the only one who feels like kids have so many days off? I never got that many days off when I was a kid! And I had to go work in the coal mine after, too!" I know what I sound like, but I just can't help it.

In Georgia, where I live, we have a shorter summer break than some other parts of the country. But my kids have the entire week of Thanksgiving off, a week in September, two whole weeks at Christmas, a whole week off in February, and a weeklong spring break. They have asynchronous days (during which they complete assignments at home, which usually takes about 30 minutes) about once a month, and they have two or three half-day weeks throughout the year. Quite honestly, it feels like they're never in school for very long before they get another break, which makes it tough to get in a rhythm with work and career goals. Plus, we're constantly arranging day camps and other childcare options for all the time off. Actually, I just looked it up and I'm not losing my mind: American kids have fewer school days than most other major countries.

So it caught my attention in a major way when I read that Whitney Independent School District in Texas recently decided to enact a 4-day week heading into the 2025 school year. That makes it one of dozens of school districts in Texas to make the change and over 900 nationally.

The thought of having the kids home from school EVERY Friday or Monday makes me want to break out in stress hives. But this 4-day school week movement isn't designed to give parents a headache. It's meant to lure teachers back to work.

Yes, teachers are leaving the profession in droves and young graduates don't seem eager to replace them. Why? The pay is bad, for starters, but that's just the beginning. Teachers are burnt out, undermined and criticized relentlessly, held hostage by standardized testing, and more. It can be a grueling, demoralizing, and thankless job. The love and passion they have for shaping the youth of tomorrow can only take you so far when you feel like you're constantly getting the short end of the stick.

School districts want to pay their teachers more, in theory, but their hands are often tied. So they're getting creative to recruit the next generation of teachers into their schools — starting with an extra day off for planning, catch-up, or family time every week.

Teachers in 4-day districts often love the new schedule. Kids love it (obviously). It's the parents who, as a whole, aren't super thrilled.

So far, the data shows that the truncated schedule perk is working. In these districts, job applications for teachers are up, retirements are down, and teachers are reporting better mental well-being. That's great news!

But these positive developments may be coming at the price of the working parents in the communities. Most early adopters of the 4-day week have been rural communities with a high prevalence of stay-at-home parents. As the idea starts to take hold in other parts of the country, it's getting more pushback. Discussions on Reddit, Facebook, and other social media are overrun with debate on how this is all going to shake up. Some parents, to be fair, like the idea! If they stay-at-home or have a lot of flexibility, they see it as an opportunity for more family time. But many are feeling anxious. Here's what's got those parents worried:

The effect on students' achievement is still unclear.

The execution of the 4-day week varies from district to district. Some schools extend the length of each of the four days, making the total instructional time the same. That makes for a really long day, and some teachers say the students are tired and more unruly by the late afternoon. Some districts are just going with less instruction time overall, which has parents concerned that their kids might fall behind.

4-day school weeks put parents in a childcare bind.

Having two working parents is becoming more common and necessary with the high cost of living. I know, I know — "school isn't daycare!" But it is the safe, reliable, and educational place we send our kids while we need to work.

Families with money and resources may be able to enroll their kids in more academics, extracurriculars, sports, or childcare, but a lot of normal families won't be able to afford that cost. Some schools running a 4-day week offer a paid childcare option for the day off, but that's an added expense and for families with multiple kids in the school system, it's just not possible.

This will inevitably end with some kids getting way more screentime.

With most parents still working 5-day weeks, and the cost of extra activities or childcare too high, a lot of kids are going to end up sitting around on the couch with their iPad on those days off. I'm no expert, and I'm certainly not against screentime, but adding another several hours of it to a child's week seems less than ideal.

Of course there are other options other than paid childcare and iPads. There are play dates, there's getting help from family and friends. All of these options are an enormous amount of work to arrange for parents who are already at capacity.

Working 4 days is definitely a win for teachers that makes the job more appealing. But it doesn't address the systemic issues that are driving them to quit, retire early, or give up their dreams of teaching all together.

A Commissioner of Education from Missouri calls truncated schedules a "band-aid solution with diminishing returns." Having an extra planning day won't stop teachers from getting scapegoated by politicians or held to impossible curriculum standards, it won't keep them from having to buy their own supplies or deal with ever-worsening student behavior.

Some teachers and other experts have suggested having a modified 5-day school week, where one of the days gets set aside as a teacher planning day while students are still on-site participating in clubs, music, art — you know, all the stuff that's been getting cut in recent years. Something like that could work in some places.

As a dad, I don't mind the idea of my busy kids having an extra day off to unwind, pursue hobbies, see friends, catch up on projects, or spend time as a family. And I'm also very much in favor of anything that takes pressure off of overworked teachers. But until we adopt a 4-day work week as the standard, the 4-day school week is always going to feel a little out of place.

History (Education)

The Statue of Liberty is a symbol of welcoming immigrants. That wasn't what she was made for.

Dr. Joy DeGruy explains how Lady Liberty's oft-ignored shackles symbolize her near-forgotten origins.

Many people are not aware of the chains at the Statue of Liberty's feet, much less why they are there.

With her flowing robes, flaming torch held high, and crown radiating out to the world like a beacon of hope, the Statue of Liberty has stood as an American emblem off the coast of New York for over two centuries.

If you were to ask the average American what they think of when they think of the Statue of Liberty, many would say she's a symbol of the liberty sought by people around the world who have come to our shores to find it. As the first American sight countless immigrants saw when they arrived at Ellis Island, with her pedestal bearing the words, "Give me your tired, your poor, Your huddled masses yearning to breathe free…" Lady Liberty has long been synonymous with the American tradition of welcoming immigrants.

But that's not actually what she was made for.

French politician Édouard de Laboulaye conceived of the idea for the Statue of Liberty to be built as a gift from France to the United States in 1865, the year the U.S. Civil War ended. That timing wasn't a coincidence. Laboulaye was a staunch abolitionist and president of the French Anti-Slavery Society, and his views were central to his commissioning of the statue. The statue was to be a gift celebrating the end of slavery in the U.S., as well as the centennial of the nation's founding and a symbol of good relations between France and America. Its ties to immigration wouldn't come until decades later.

Dr. Joy Degruy, sociologist, educator, and author of "Post-Traumatic Slave Syndrome: America's Legacy of Enduring Injury and Healing,"" shares a story about visiting the Statue of Liberty in her book and talks. She recounted the story to Brandi Harvey on the Vault Empowers podcast, informing people—many for the first time—that the Statue of Liberty's origin story began with anti-slavery activism, not immigration.

Watch:

— (@)

As Dr. DeGruy explains, the original design had Lady Liberty holding broken chains in her left hand, not the tablet we see today. Sometime between the original drawings and the final design, those chains were moved to her feet—where they aren't visible unless you are flying through the air over them—and the tablet bearing the date July 4, 1776 in Roman numerals took their place.

Exactly how and why that change was made is not entirely clear in the historical record. But the fact that it even happened has not been widely shared, even by the people giving tours of the statue and sharing her history. DeGruy asked the tour guide about the chains on a visit and went on a hunt for the historical document showing the original design.

"So we go into the basement of the Statue of Liberty," she said. "We're in the basement of the Statue of Liberty. We find the document—encased in glass, behind figurines, facing a wall in a hallway. So here we have the truth, hidden in plain sight."

— (@)

In a deep dive of the written historical records we have, researcher Rebecca M. Joseph, PhD. fact-checked various myths about the statue and her findings verified her anti-slavery origins as one of two parts of Laboulaye's vision of celebrating American liberty:

"The Statue of Liberty would never have been conceived or built if its principal French and American advocates had not been active abolitionists who understood slavery as the cause of the Civil War and its end as the realization of the promise of liberty for all as codified in the Declaration of Independence. But the Statue of Liberty was not intended entirely as a monument to the end of slavery. The statue’s form after June 1871 clearly embodies Laboulaye’s views on the two-part realization, in 1776 and 1864, of his ideal of liberty. The centennial of the American Revolution was significant to the French sponsors because the Civil War ended slavery and preserved the Union at a time when the France’s future was still uncertain. For the American republicans, it was a timely opportunity to erect a monument to their efforts and worldview. Laboulaye and his French colleagues also wished to send a political message back to France. Bartholdi cast the project in the broadest terms, hoping to encourage additional commissions."

So how did we come to associate the Statue of Liberty with immigration? That's another interesting story, as Joseph explains:

"The conventional interpretation of the statue as a monument to American immigrants is a twentieth-century phenomenon. In its early years (1871-1886), that view was only rarely and vaguely expressed, while references to the Civil War and abolition of slavery occur repeatedly from its first introduction to the United States in 1871 up to and including the dedication celebrations in 1886. Immigrants did not actually see the Statue of Liberty in large numbers until after its unveiling. In the early twentieth century, the statue became a popular symbol for nativists and white supremacists. Official use of the statue's image to appeal to immigrants only began in earnest with public efforts to Americanize immigrant children and the government’s advertising campaign for World War I bonds. The 'immigrant' interpretation gained momentum in the 1930s as Americans prepared for war with Hitler and by the 1950s, it had become the predominant understanding of the statue's original purpose and meaning."

Since DeGruy raised the issue of the exclusion of the statue's anti-slavery origins, the Statue of Liberty national monument and museum has updated its educational program to include them. For some, it might seem like a mere factual correction, but for Black Americans who visit the Statue of Liberty, De Gruy says, it could potentially change their whole relationship to her symbolism.

"When Black people walk through, you hear white people say, 'Oh well, you know, my great great, and my great great…' but Black men, women, and children feel no connection to Lady Liberty. But how much prouder would they be if they knew that their ancestors that didn't come through Ellis Island, that came chained together in the belly of ships, that she was standing on those shackles? How much prouder would those young people be?"

Dr. DeGruy shared more about how Black Americans can find healing through hidden history. You can watch the full Vault Empowers interview with her here:

People are finding healing from woman's sweet 'welcome to girls night in your 30s' video

"This is the post every girl needs to see."

@danilyndesign/TikTok

30s look different for everyone

A 6-second video showing a handful of 30-something friends having a “girl’s night” is striking a heart nourishing nerve for millions.

In the video, posted by @danilyndesign, the camera pans over the group as the caption depicts the scene:

“Girls nights in your 30s. We're holding one girl’s babies, one girl is showing her hinge matches, while another girl is laughing about her ex husband.”

And then, Dani drives the point home:

“You’re never behind in life. You are exactly where you are meant to be right now.”

@danilyndesign Girls nights in your 30’s are what my younger self dreamed of. #girlhood #femalefriendship #girlsintheir30s #girlsnight ♬ Take My Hand - Matt Berry

With its simple yet profound message, it’s no wonder that the clip quickly racked up nearly 6.5 million views on TikTok, and spawned a ton of lovely conversations.

For one thing, people noted how it added a touch of nuance to the “it takes a village” concept. Often we think of villages as a necessity (or luxury, these days) for parents only, when in fact having a safe community is vital for everyone.

“This is ‘the village’! It's not moms at the center, it’s everyone that matters and everyone’s lives are valued and respected," one person commented.

Viewers also felt a sense of relief seeing how each chapter of life seemed to be fully embraced by the friend group. After all, everyone in their 30s has had their own personal set of milestones, challenges, heartbreaks, existential crises, that have helped shape the adult they are. Not always, but often, a lot of the arbitrary pressures we put on ourselves begin to dissolve by this age, so that we can better appreciate where we actually are in life, wherever that may be.

“Beautiful and remember no matter where you are in the journey, we are allll just figuring it out day by day. Find joy in it wherever you can” one person wrote.

Another added, “I want to tell every woman stressed in their twenties that their thirties will be better, they just need to trust themselves and hang in there.”

“This is the post post every girl needs to see,” wrote a third. “You’re exactly where you need to be.”

For some, this particular insight came at just the write time.

“Needed this. I’m 28 turning 29. My besties are all either engaged/married with a kid and I can’t get past the talking stage. Then I remember our paths are different and I’m where I need to be right now,” confessed one viewer.

Lastly, people had so much love for how this perfectly captured the immense value of long-term friendship. As one person wrote, "growing and evolving with friends is the most beautiful thing. They’ve seen so many versions of us and love them all.”

Another said, “Like in White Lotus when she said ‘I;m just happy to be at the table.’”

As cliché as it is, life truly isn’t about the destination—it’s about the journey. And those beloved relationships we cultivate along the way. We all contain multitudes, and hopefully our friend hangs can help remind us of that when we need it.
