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.

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!!"

Woman reveals how people get such long-lasting spray tans and it's grossing people out

As a first-timer, she was shocked at the instructions.

Woman is disgusted after learning the truth behind lasting spray tans.

Not everyone tans easily, and for some, reducing the risk of skin cancer and premature excess wrinkles is more important than laying out with a bottle of baby oil. For those who want a tan without the massive amounts of UV exposure, spray tanning is a good option. You can get the sun-kissed, recently back from vacation look without the risk.

The process is simple. You walk into a room and someone comes in with what looks like an airbrush gun and sprays a nice even layer or two of artificial melanin on your skin. It can even out your skin tone, leaving your skin looking healthy and more vibrant. There is a catch though–it's temporary.

Technically a summer tan acquired the old-fashioned way is also temporary, but it generally takes weeks or months to completely fade away. But a spray tan only lasts about 5-10 days depending on how well you "care" for it. A woman who goes by the name Miss Redacted on TikTok recently received her first spray tan, and when given the instructions for how to extend the life of her spray tan through "proper care," she was left flabbergasted.

Of course, when you get something done to your body you are expecting that there will be specific instructions on how to care for the new thing. Whether it's a piercing, a tattoo, or even a chemical peel, you expect an overload of informative care instructions before you're allowed to leave the place you received the service.

So the woman was not surprised to receive the rundown on making sure her skin remained glowingly sun-kissed for as long as possible. What she wasn't expecting was the lack of care. Or maybe the better description would be the lack of hygiene required to maintain her newly tanned skin.

"Recently I got a spray tan for the first time because I really like being tan but I don't want to have wrinkles later because I'm obviously very vain. So I went the first time and I expected that I wouldn't be able to shower normally for the first 12-24 hours, and that didn't bother me that much because I'm like, okay, I understand the tan has to set in. I can be gross for a half a day, a day max, whatever, it's not that serious," Miss Redacted says before explaining the woman who did her spray tan began talking her through the process.

The confused woman recalls a roommate in college who used to get spray tanned all the time as she put the pieces together on hygiene and spray tans. She tells the person doing her spray tan that she generally showers twice a day using soap and a silicone scrubber to wash her entire body, to which the spray tan artist immediately tells her not to use the scrubber on her body because it will take her tan off.

"I was like, 'Oh so don't use it the first shower?' and she was like 'No, like not at all.' And I was like 'What should I use instead of that?'" the first-time customer explains.

She was shocked to hear the artist tell her that she needed to switch to a washcloth and only use it to wash her, "underarms, your bikini area, and under your bra line." Again, Miss Redacted clarifies that means for the first shower only, but the artist reiterates not to put soap on your body "at all" for the first shower, only using a washcloth in the areas she previously mentioned. Once again, the woman was dumbfounded and asks again, what the spray tan artist means.

"I was like, 'what do you mean?' And she was like, 'if you want your tan to last the full 10 days, when you shower only use soap in those areas and just do water everywhere else,'" she says.

There was no getting around the idea that in order for the spray tan to last the woman was not going to be able to properly wash herself and she was thoroughly uncomfortable with that idea, informing the artist that she was going to continue to bathe regularly. Miss Redacted was told that if she bathed like normal her spray tan would only last five or six days.

"Because I got down this rabbit hole, I started reading about it on Reddit and some of the ways that girls were saying they maintained their spray tans is absolutely insane. Absolutely insane. Like y'all need a bath. Y'all need a...actually a hose down. Let's like put you in the yard with some Dawn, like you're one of the ducks in an oil spill. I think that's what's needed at this point," the woman jokes before clarifying that she doesn't think every woman getting spray tanned is avoiding bathing.

But when it comes to the ick factor over the ones who have been skipping the shower for weeks at a time, the woman isn't the only one feeling the heebie jeebies. Commenters are also shocked and a little grossed out.

One person summoned knowledge from the legal scholar, Elle Woods, saying, "I can see not washing for 24 hours in order to not activate the ammonia thioglycolate."

"I will just continue to embrace my Morticia Addams aesthetic then because I will be scrubbing," another woman says.

"What do you mean? WHAT DO YOU MEAN," one person demands, seeking answers that likely involve soap and water.

"The first time I spray tanned, I used a washcloth and most of the tan came off. I knew at that moment people aren't showering properly. There is no way a spray tan is lasting 10 days," a commenter reveals.

Other people explain how they get their spray tans to last longer while continuing to shower daily by using tinted moisturizers and body lotions that have a gradual tanner in it. The consensus seems to be that regular spray tanning is expensive without finding an affordable alternative to maintain the tan between sessions while continuing to bathe, but spray tanning before a special occasion is preferred. Who knew hygiene after spray tanning was such an involved art form?

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.

Photo by National Cancer Institute on Unsplash

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.

CEO shares 5 things he's 'sick' of hearing from his staff and people are applauding him for it

"People are sick of being treated like children."

via Rob Dance (used with permission).

CEO Rob Dance holds a list of things he's "sick" of hearing from his employees.

Since the COVID-19 pandemic disrupted workplaces worldwide, there has been a greater push for improved work-life balance and many companies are taking notice. The exciting thing is that when companies become more flexible, their employees become happier and more productive. It’s a win-win for all involved.

Rob Dance, the CEO of ROCK, a technology consulting company in the UK, recently went viral for posting about his approach to work-life balance on Instagram. What, at first, appeared to be a CEO reprimanding his employees revealed a boss who knows how to get the best out of his team by treating them like adults.

The post was of Dance holding a whiteboard that reads:

Things I’m sick of hearing from my employees:

- Can I leave early today

- I’ll be late in the morning

- My child is sick, can I rush off

- I’ve got a doctor’s appointment tomorrow, is that okay

- I’m going to be late back from lunch, I’ve got some things to sort.

I don’t care.

I hired you for a job and I fully TRUST you to get it done.

I don’t need you to account for every single hour.

Times have changed, and the workplace is different these days.

People are sick of being treated like children.

All that should matter is that everyone is happy, and that the work gets done.


He also shared his advice for companies on how to treat their employees. “Treat your staff like adults. That’s it, that’s the big secret,” he wrote. “Give them autonomy. Respect that they have lives outside of work. Don’t gaslight them into being grateful for not being fired every day.” Because in the end, the only thing that matters is if they get the job done. “Output should always trump hours,” he concluded.

Upworthy contacted Dance, who explained why managers still hesitate to treat their employees like adults.

“Many bosses don't trust their employees and keep extremely close tabs on them because of past experiences and a desire for control. They might believe that micromanaging ensures productivity and prevents issues,” he told Upworthy. “Additionally, the pressure to meet business targets can drive bosses to monitor employees obsessively, thinking it will lead to better outcomes. This approach, however, only undermines trust and destroys morale in the workplace. It creates a toxic environment where employees feel undervalued and stressed, leading to higher turnover rates and decreased overall performance. Instead of fostering a culture of accountability and growth, this behavior only promotes fear and resentment.”


Dance says that technology has helped drive demand for improved work-life balance.

“Mobile technology definitely started to blur the lines between one’s professional and personal life, making it tough to switch off from work,” he told Upworthy. “As a millennial leader, I've always valued work-life harmony for my staff, helping them to achieve both flexibility and finding purpose in their work.”

The ROCK CEO also has advice for employees who’d like to gain their employer’s trust.

“Always deliver quality work and aim to meet or exceed expectations. Keep communication lines open by regularly updating your manager on your progress, challenges, and successes,” he told Upworthy. “Take the initiative to go beyond basic requirements, showing your willingness to contribute more. Act with integrity by always being honest and ethical. Seek honest feedback and make tangible improvements based on it, demonstrating your commitment to growth. Finally, a big one is building positive relationships with everyone you work with, as strong connections are what help to build real trust.”

In April 2025, Dance shared some additional wisdom that highlights the power of leaders prioritizing culture. He took a photo of himself holding a whiteboard with some more wisdom that all CEOs should take to heart: "An employee who leaves for the salary might return for the culture, but if they leave because of the culture, no salary will ever bring them back."

It makes you wonder, if the money was right, which previous jobs would you go back to, and which ones would you reject?

Mom shares 'kind can' idea after 7-year-old expresses struggles with friends at school

She described the "kind can" as "a way to keep our hearts open even when they want to close.”

Sasja Nieukerk-Chomos/Facebook

The "kind can" is a tool for helping kids connect with others.

At some point, most parents have to field questions, concerns, worries, anxieties, and, sometimes, outright despair from their kids about their relationships with other kids. Friendships can be messy. Bullying is a thing. When you pool together a couple of dozen kids who are growing, changing, and figuring out their emotions for most of the day, all manner of relational dynamics can emerge.

Navigating the social landscape with our kids isn't easy. Each child is unique, some are more sensitive or aware of what's happening than others, and some need assistance with figuring out how to handle tough social situations. As parents, we don't want to swoop in and solve their problems, but we also don't want to leave them rudderless in a storm. We want to provide them with the tools and help them build the skills they'll need to steer their own ship.

kids, parenting, parents, tweens, issuesFinding the right balance can be tough.Image via Canva

One tool that can help a kid who is struggling to connect with their peers is intentional kindness. However, a blanket admonition to "be kind" is often too vague to help a kid in the midst of a social crisis. That's why one parent's "kind can" idea has gone viral—it offers a specific way to practice kindness in a way that's not overwhelming.

In a 2022 post on LinkedIn, mom Sasja Nieukerk-Chomos shared the idea, writing:

"'Mom, I hate them.'

'Them' being her friends at school.

This is what my 7-year-old confided to me as I was putting her to bed the other night.

I could have made light of her hatred, like I’ve done when she tells me she hates broccoli.

I could have gotten caught up in her anger: 'Who are these kids upsetting my daughter!?'

Instead, I asked her what was going on that her heart hurt so much.

Because under anger is usually hurt."

"Sure enough, the tears came pouring out as she told me about how her best friend only wanted to play with another girl, and how when she went to find others to play with they told her to go away.

This had been happening all week.

'Why doesn’t anybody like me?'

I didn’t have an answer for that, but I did have a thought: It’s time for the Kind Can.

Suddenly I was 8 years old again, a grade 3 student who was having a rough start to the school year.

I had a teacher I didn’t like, friendships had shifted, and I couldn’t seem to get along with anyone. I hated going to school.

My mom created a Kind Can.

She used a big Nescafe tin can (remember those?)

In the can went the names of every single one of my classmates. Each morning before school I
would pull a name out of the can. That day I had to go out of my way to do something kind for them.

Not to have them do something in return.

For no other reason than to do something kind.

It wasn’t easy at first, but my mom encouraged me to keep trying, and helped me think of all the different ways I could show kindness to others.

It started to get really fun!

And then things shifted.

No longer caught up in my own mind about what others were ‘doing to me’, I was now focused on what I was doing for others.

Though there were no expectations of kindness in return, more and more kindness is what I got. I loved going to school!

I told my daughter about the Kind Can and her eyes got that little spark – the one that tells me she’s about to get creative.

So yes, she has big plans for just how fancy this can will be – much better than an old tin can she proclaimed! That’s our project.

A Kind Can.

A way to create more kindness.

A way to keep our hearts open even when they want to close."

People loved the "kind can" idea, with the post being shared more than 3,000 times. Some people pointed out the beauty of the wisdom in it being passed down through generations. Several parents wished that they had seen the idea when their own kids were going through some social struggles. Many commenters said that a lot of adults could use a kind can as well.

With bullying becoming more widespread thanks to the Internet and social media, many parents are aware of the importance of instilling kindness in their children. On social media, parents are making a point to highlight moments of kindness from their own kids or from another kid to theirs, and the videos are warming hearts and reminding viewers that the kids really are all right—and will continue to be so long as we continue to model kindness like Nieukerk-Chomos.

@ismeganokay

When I tell you I burst into tears when that girl offered her her hand… a small gesture can mean so much | #bekind #endbullying #adhd #parenting

A "kind can" won't solve every friendship woe a child has, but goodness knows the world could use more kindness. Helping kids practice that virtue with a tool that makes it specific and fun is definitely a win-win.
