This teen came up with a wildly smart invention to help his grandpa cope with Alzheimer's.

Meet Kenneth Shinozuka.

He lives with his grandpa. They're really close.

Unfortunately, Kenneth's beloved grandpa suffers from Alzheimer's disease.

Within a few years of being diagnosed, his grandfather started getting up in the middle of the night and wandering off — once even onto the freeway. He and his family were woken up when a police officer brought him back (safe, thankfully!).

"It was very real and very scary," Kenneth said in an NBC interview.

Kenneth wanted to find a way to keep his grandpa safe. So he invented something awesome.

...a simple sensor that attaches to a sock and alerts a caregiver's smartphone if the wearer wanders out of bed.

Kenneth's invention is so good, it won him a Science in Action award from Scientific American.

The sensors are now being tested by patients in a nursing home, with some impressive results.

This isn't just a win for Kenneth and his grandpa. Over 5 million Americans have Alzheimer's.

Roughly 60% of these folks will, at one time or another, wander off.

Kenneth's simple sock device can keep so many of our loved ones safe.

Not too shabby for a 15-year-old.

For full dose of heartwarming goodness, check out the video:

And here's a little more info on Kenneth's invention:

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!!"

Robin Williams saw a struggling comedian bomb on stage. He changed her life with one sentence

They had never met but Williams knew exactly what to say.

ha.wikipedia.org

Robin Williams performs on stage.

Robin Williams once beautifully said, "I think the saddest people always try their hardest to make people happy. Because they know what it feels like to feel absolutely worthless and they don't want anybody else to feel like that."

One night at a comedy club in Los Angeles, a new, nervous stand-up comic was called to the stage by the emcee. In one hand, she casually had a beer that she propped up on the piano. In the other, was her notebook full of scribbled, half-written joke premises and a few wine stains. She did her opening joke and the response was so quiet, she could hear the ice machine crackling in the kitchen. Joke two — a slight spattering of nervous laughter. Joke three got a heartier laugh, but then it went back to deafening quiet by joke four.

She mercifully got through her final joke, and said "That's my time" long before the red light in the back of the club even went on. She scurried off stage with her beer, like that rat in New York carrying a piece of pizza. Panicked, embarrassed, and frankly — a little hungry.

It was just one of those nights. The last time she'd done this act — same words nearly exactly — she'd received an applause break. This time, she was left questioning every one of her life decisions. Why had she come to Los Angeles? How was the next month's rent supposed to get paid? Why had she cut her hair in the "Rachel-styled" haircut?

As she was about to enter the hallway that led into the bar area, she could feel actual tears forming behind her eyes, like little faucets that were slowly turning on. "Don't cry at the comedy club," she told herself. Rather, "Don't cry at the comedy club AGAIN." But as the tears came anyway, she looked up and lo and behold, there was Robin Williams. She stuttered, "You. Are. One of my favorites. Ever." He looked at her, his blue eyes warmly crinkling and said, "You were amazing."

It hadn't been true. But the fact that he would go out of his way to make this total stranger's awful night into one of her best at that time, was just the kind of person Robin was.

I know this because that woman was me.

I wanted to tell him about the Mork and Mindy poster on my wall as a kid, and how I had cut out Mindy's face and put in my third-grade class photo. I wanted to tell him how much I loved his care for animals and for the unhoused and for the less fortunate. Or that because of him, I had a weird fetish for suspenders. (The last one wasn't quite true, but I still wanted to say it.)

But instead I merely laughed and said "Oh, thank you. But I can do better." He gave me a gentle look like, "We're all in this together," and even though I knew I'd never have a career like his, it dawned on me that it didn't matter. That being kind to others actually DID matter and that he was a lighthouse in a really stormy, pitch-black ocean.

I stuck it out and just a few years later, got to perform in the super cool and coveted "New Faces" show at the Just for Laughs Montreal Comedy Fest. Didn't kill there either, but I was able to step back and look down from an aerial view. How we uplift others, whether through laughter or kindness, is really the only control we have in this world.

Years later, after Robin passed away, I had heart surgery and was feeling down. I had read that cardiac issues could leave a person biochemically depressed and the first person I thought of was him. I messaged our mutual friend from San Francisco and asked if he remembered Robin speaking to him about heart surgery and depression. He only affirmed that yes, it was a very real side effect and that I should take it seriously.

I have always thought of the neurotransmitter Serotonin like it was a flowery perfume. Notes of honey, lavender, rose. When someone has a good amount of it floating through their synapses, it leaves trace of itself wherever it goes, as if the tunnels it burrows under pumps it out through a steam grate. But from what I've heard, Robin struggled with that too. And yet he still found a way to leave a lovely and inviting scent behind him, because he wanted to make sure OTHERS were okay.

I guess, even in his death, I was looking to Robin for answers. But one puzzle remains solved: making others happy is the kindest thing we can do, even when our own valves --- whether heart or perfume pumps --- fail to work.

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.


Giphy

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.

Giphy

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.

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.

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.

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:
