If this looks familiar, you may have cataracts. 2 new sci-fi fixes could help.

If you saw these pictures in a gallery, you might think the glass was smudged.

You'd obviously want to get someone to clean it up!

But what if the smudge was inside your eye?

Inside your eyes are natural lenses, like the lens of a camera. The lens focuses light onto the back of our eyes, where specialized cells interpret the image and send that information to the brain. Because all the light we see has to go through the lens, our bodies naturally make it transparent.

Sometimes, however, proteins in the lens start to clump together, forming a small cloudy area that destroys that carefully constructed lens transparency, like replacing a camera lens with a piece of frosted glass. This cloud is what's known as a cataract, and over time, it can spread to cover the entire lens in the eye.

When this happens, cataracts cause our vision to become blurry and washed out. They can also make light glare really bad and give some people double vision.

More than 22 million Americans over 40 already have cataracts. By the time we turn 80, most of us will have them in some form.

Cataracts are the leading cause of blindness in the world and mostly happen to people as we age. They can also be found in children and younger adults due to congenital conditions, injury, or illness. About one in every 250 kids is born with or develops cataracts at young age.

Treatments for cataracts do exist. The current solution generally either involves stronger glasses or, if the vision loss is bad enough, surgery to replace an old, cloudy lens with a transparent plastic one.

But cataract surgery does sometimes come with complications, and some types of the plastic replacement lenses sacrifice the flexibility of our biological lenses — they have trouble focusing on nearby stuff, for instance, and don't work super well in children.

Cataract surgery might be about to get a neat sci-fi upgrade thanks to new research involving stem cells.

Stem cells are a special kind of cells found in our bodies that can transform themselves into different types of cells (like eye cells or brain cells or kidney cells).

They've been a hot area of research, from anti-aging ideas to straight-up regenerating limbs.

Two groups of researchers recently published studies investigating if stem cells could help re-grow biological lenses.

One group of researchers in Japan and the U.K. recently used human stem cells to grow cells from many different parts of the eye.

The scientists took human stem cells and coaxed them into transforming into eye tissue. They found that they could successfully make the cells divide into different layers as they grew.

What's cool is that each layer corresponded with a different part of the eye. Cells from the first layer, for example, could potentially become part of the nerve-rich tissue at the back of the eye while cells from between the second and third layers could become the lens, and cells from layers 3 and 4 could become parts of the cornea.

The researchers were even able to successfully transplant the new stem-cell-grown corneas into rabbits. This technique could one day help doctors replace many different parts of people's eyes as they become damaged, although a lot of work needs to be done before we see any tests in humans.

Another research group, meanwhile, experimented with a surgical technique designed to help children regrow new lenses.

The technique is deceptively elegant because it doesn't require any new technology, just a twist on existing techniques.

“This is just a change in a surgical procedure,” said James Funderburgh, a cell biologist at the University of Pittsburgh in a Nature press release. “They are not putting in an artificial lens: they are just letting the lens regrow.”

In this new technique, the surgeons use a smaller-than-normal incision to remove the patient's cloudy lens but don't implant a plastic one afterwards. That's because after the lens is removed, some stem cells are naturally left behind in the patient's eye, and it turns out that, by leaving them alone, the body can use those stem cells to grow a brand new lens.

This technique is slower than traditional methods because the child's eye needs about three months to grow a new lens. But the benefit is that the lens won't grow cloudy over time, like some artificial ones do, and the surgery has a much lower rate of complications.

In fact, this technique was so successful, they've even used it on 12 human babies. It's been two years since some of them had the procedure done, and so far, the results seem promising. While this particular technique may not be as useful for older adults (whose cells grow more slowly), it could restore sight to a lot of young people.

“Even if it’s only for kids, it’s fantastic,” said Funderburgh.

Cataracts are one of the most common vision problems in the world, but these cool new tools could help those living with them see the world a whole lot more clearly.

All parents have had similar convos with thier kiddos.

Raising kids is tough, but there's a lot of laughs along the way. Especially when actual conversations start, as kids begin trying to make sense out of the world around them, ask questions, and test mommy and daddy's resolve.

Back in 2018, comedy writer and children's book author James Breakwell, with four daughters who were all under the age of eight at the time, shared their hilarious conversations on X. From these tweets, it looks like comedy runs in the family. Here's a sampling of some Breakwell's funniest kid-inspired tweets.

 


 


 


 


 


 


 


 


 


 


 


 


 


 


 


 


 


 


 


 


 


 


 


 

While Breakwell's 7-year-old wasn't as heavily featured, when she was quoted, the sarcasm was palpable. Which makes sense, considering that kiddos begin understanding this mechanism around that age.

 


 


 


 


 


 


 


 


 


 


 


 


 

Kids really do say the darnedest things, and we love them for it. It one of the many, many ways then bring so much joy to the world. It almost makes up for the headaches and sleepless nights, doesn't it.

30 cheap and delicious meals frugal people swear they never get sick of

"I could eat one every day of my life if I allowed it to happen."

Frugal people share cheap meals they love.

Groceries are a major expense these days. And grocery prices are continuing to go up in 2025, according to the USDA. Still, making meals at home versus going out to eat is cheaper, and a big way to save money. But getting creative with low-cost ingredients can be a hang-up.

In an online community of frugal people, member samdaz712 posed the question to fellow savers: "What’s the cheapest meal you actually enjoy eating regularly?"

They continued, "We all have that one budget meal that somehow never gets old. For me, it’s rice, eggs, and frozen mixed veggies with soy sauce and chili flakes. Costs next to nothing, takes 10 minutes, and I actually look forward to it."

The post wrapped up with a call-out for others' favorite and frugal meals. "Curious what everyone else’s go-to cheap meals are not the I’ll suffer through this to save money kind, but the ones you genuinely like and would still eat even if you weren’t budgeting. Always looking for new ideas that don’t break the bank," they added.

Frugal people happily shared their cheap (and yummy) go-to meals. Here are 30 cheap meals that they never get sick of.

"PB&J sandwiches. I could eat one every day of my life if I allowed it to happen. If I'm feeling fancy, I'll make a PB, banana, and honey sandwich. Then I'll pan toast with a generous amount of butter on each side until the bread is golden brown and the PB starts to melt. It's so decadent yet so cheap." - Kom4K

"Fried egg sandwich." - Major9000

"Every week-ish we make pinto beans, smash em up into a refried situation, melt some cheese, spread them on toasted torta bread with avocado. Then use leftovers in your eggs the next day or make burritos for lunch. You can never go wrong with a pot of beans." - BoardNo1459

"A pot of pinto beans with a link of kielbasa sausage and corn bread...Absolute baller." - Bigram03

"'Hobo-potatoes,' diced potatoes, onions, salt and pepper, mixed up in a bag of foil with oil and left to cook in the coals of a camp fire. Goes great with any protein and has more potassium per serving than bananas." - BlaqueNight

"Pasta and butter. Sometimes with grated parmesan." - RuthlessLidia

"Quesadilla." - babe_ruthless3

"Toast." - FrauAmarylis

"Pan fried tofu slabs braised in a pan with chopped kimchi, green onion, kimchi liquid or rice vinegar, soy sauce, sesame oil, bit of water to make it saucy, a tsp of sugar seems to help it meld together. Takes 10-12 min. Served over short grain rice. Optional toppings, toasted sesame seeds, chopped cilantro, sliced green onion. Edit: this was from The NY Times food, from Sue Li for exact proportions." - LavaPoppyJax

"Costco’s $1.50 hot dog and drink." - StarWolf478

"Rice and eggs for me too. It can be enjoyed in so many ways! My favorite is a crispy egg that’s still yolky on sushi rice with seaweed, salt and sesame oil." - theyrejusttoys

"For me it's an egg foo young - type dish! Stir raw eggs into leftover cooked vegetables (and optional protein, like leftover chicken or whatever you have). Ladle the mixture into a hot pan with a little oil, and fry up into patties. Serve over rice, and top with a drizzle of some kind of Asian sauce and a little hot pepper. You can look up a recipe for Egg Foo Young sauce, but that's not necessary; it tastes great with almost any kind of Asian sauce, or simply soy sauce. The cooked patties last for days in the refrigerator and can be reheated. Bonus: This is a fantastic way to use up any small bits of leftover veggies or meat. And if I have wilted vegetables that are in danger of spoiling, I just chop them up and quickly sauté them together, and freeze them in small containers. Now I have lots of veggies ready to go to make delicious egg foo young." - TIL_eulenspiegel

'Wicked' author says one line in 'The Wizard of Oz' inspired Elphaba and Glinda's backstory

Gregory Maguire says he "fell down to the ground" laughing when the idea hit him.

Public domain

The two witches in "The Wizard of Oz" clearly had a history together.

Have you ever watched a movie or read a book or listened to a piece of music and wondered, "How did they come up with that idea?" The creative process is so enigmatic even artists themselves don't always know where their ideas come from, so It's a treat when we get to hear the genesis of a brilliant idea straight from the horse's mouth. If you've watched "Wicked" and wondered where the idea for the friendship between Elphaba (the Wicked Witch) and Glinda (the Good Witch) came from, the author of the book has shared the precise moment it came to him.

The hit movie "Wicked" is based on the 20-year-old hit stage musical, which is based on the novel "Wicked: The Life and Times of the Wicked Witch of the West" written by Gregory Maguire. While the musical is a simplified version of the 1995 book, the basic storyline—the origin story of the two witches from "The Wizard of Oz"—lies at the heart of both. In an interview with BBC, Maguire explained how Elphaba and Glinda's friendship popped into his head.

 

Maguire was visiting Beatrix Potter's farm in Cumbria, England, and thinking about "The Wizard of Oz," which he had loved as a child and thought could be an interesting basis for a story about evil.

"I thought 'alright, what do we know about 'The Wizard of Oz' from our memories,'" he said. "We have the house falling on the witch. What do we know about that witch? All we know about that witch is that she has feet. So I began to think about Glinda and the Wicked Witch of the West…

 glinda, elphaba, wicked,  In "Wicked," the two Oz witches met as students at Shiz University.  Giphy GIF by Wicked 

"There is one scene in the 1939 film where Billie Burke [Glinda the Good Witch] comes down looking all pink and fluffy, and Margaret Hamilton [the Wicked Witch of the West] is all crawed and crabbed and she says something like, 'I might have known you'd be behind this, Glinda!' This was my memory, and I thought, now why is she using Glinda's first name? They have known each other. Maybe they've known each other for a long time. Maybe they went to college together. And I fell down onto the ground in the Lake District laughing at the thought that they had gone to college together."

In "Wicked," Glinda and the Wicked Witch, Elphaba, meet as students at Shiz University, a school of wizardry. They get placed as roommates, loathe each other at first, but eventually become best friends. The story grows a lot more complicated from there (and the novel goes darker than the stage play), but it's the character development of the two witches and their relationship with one another that force us to examine our ideas about good and evil.

Maguire also shared with the Denver Center for Performing Arts what had inspired him to use the "Wizard of Oz" characters in the first place.

"I was living in London in the early 1990’s during the start of the Gulf War. I was interested to see how my own blood temperature chilled at reading a headline in the usually cautious British newspaper, the Times of London: 'Sadaam Hussein: The New Hitler?' I caught myself ready to have a fully formed political opinion about the Gulf War and the necessity of action against Sadaam Hussein on the basis of how that headline made me feel. The use of the word Hitler – what a word! What it evokes! When a few months later several young schoolboys kidnapped and killed a toddler, the British press paid much attention to the nature of the crime. I became interested in the nature of evil, and whether one really could be born bad. I considered briefly writing a novel about Hitler but discarded the notion due to my general discomfort with the reality of those times. But when I realized that nobody had ever written about the second most evil character in our collective American subconscious, the Wicked Witch of the West, I thought I had experienced a small moment of inspiration. Everybody in America knows who the Wicked Witch of the West is, but nobody really knows anything about her. There is more to her than meets the eye."

Authors and artists—and their ideas—help hold a mirror up to humanity for us to see and reflect on who we are, and "Wicked" is one of those stories that makes us take a hard look at what we're seeing in that mirror. Thanks, Gregory Maguire, for launching us on a collective journey that not only entertains but has the potential to change how we see one another.

Walt Disney and Ray Bradbury.

The world’s greatest innovators think and behave differently from us mere mortals. They have a unique view of the world and are dedicated to their craft in ways that most would deem obsessive. But without that type of dedication, Steve Jobs could never have given us the Macintosh, Michael Jordan would never have been able to fly, and Michelangelo would have never painted the Sistine Chapel.

It’s hard for the average person to understand what makes a cultural innovator tick, which is why an interview with groundbreaking author Ray Bradbury on Walt Disney is so inspiring. It lifts the veil on what great artists see in one another that most of us can’t. Bradbury is the acclaimed author of classics such as Fahrenheit 451 and The Martian Chronicles, who was a friend of Disney and worked with his legendary company as a creative consultant.

What did Ray Bradbury think of Walt Disney?

In a 2004 interview, Bradbury explained where the incredibly ambitious and creative Disney got his drive and determination.


“If there’s any secret at all, it’s because Walt, like myself, is not an optimist but an optimal behaviorist. Which means that every day of your life, if you behave well, you begin to feel well,” Bradbury said. “So that’s not false, that’s real. You get your work done every day, and at the end of a week, a month, a year, you’ll turn around and say, hey, look what I did. So you feel good. That’s real optimism. Optimal behavior.”

“He could look back at the end of each year and see his behavior, and it made him want to go on. A lot of people are pessimists because they’ve never done anything,” Bradbury continued. “If you go to bed every night having not done anything, you’re going to wake up unhappy, aren’t you? So the answer to that is do something every day. Be busy, for God’s sake, be busy.”

What is a behavioral optimist?

Although “behavioral optimist” isn’t an official psychological term, it’s one that Bradbury often used to describe himself. “I’ve learned that by doing things, things get done. I’m not an optimist; I’m an optimal behaviorist. We ensure the future by doing it,” he said. “Optimists and pessimists are blind. But I’m not either. I’m an optimal behaviorist. In other words, I behave at the top of my lungs every day. There’s no guarantee, but you’re going to have a heck of a lot of fun. You’ll come to the end of your life with the secure knowledge that you tried everything.”

There are just two critical things in life, he said, “Being in love with your wife or husband and being in love with your work. And then everything’s fine.”

If you’ve always dreamed of living a life like Walt Disney, using your imagination to entertain and uplift humanity, you can start by looking at life in the same way. Big goals can often seem too lofty when we think about the finished product. Instead, take small, consistent steps every day towards achieving your goal. Writing a 300-page book may seem like too much work, but if you write a page a day, you’ll have a book before the end of the year. The key is to stay focused and consistent, just like Uncle Walt.

What an amazingly kind gesture.

Closed adoptions—meaning adoptions with no contact between the biological parents and adoptive families—offer privacy, protection and emotional closure. However, it can understandably still be incredibly difficult for biological mothers to instantly and drastically remove their biological child from their life, even if they know they are doing what's best.

This was the case for Alicia Mae Holloway’s biological mom. In a video shared to her TikTok account, the dancer and television personality shared that her adoptive mother, Evelyn, “saw how hard it was” for her birth mom to give Holloway up for adoption. So Evelyn came up with a kind gesture that Holloway dubbed “the sweetest thing.”

“She was like, ‘okay, I’ll make you a deal. Every six months, I’ll send you a picture of Alicia and a little update in a written card of how she’s doing.’”

Getting those biannual letters out wasn’t as simple as dropping them off in the mail either.

As Holloway explained, she had been conceived during an affair her birth mother—a white woman, married to a white man, with three white children—had with a Black man. Not only could Holloway’s birth mom not afford a fourth kid, she feared what her “racist” family might do upon seeing a biracial baby, and told everyone that it was a stillborn.

All this to say, Holloway’s birth mom didn’t want the letters arriving at her home, potentially risking anyone from her family seeing it. Evelyn would therefore need to send the letters to a friend’s house.

But sure enough, Evelyn kept good on that promise. For 17 years, Holloways' birth mom got to celebrate milestones in her daughter’s life. Meanwhile, Holloway had no idea this exchange was happening.

“I get chills when I think about how she was watching me grow up and I had no idea,” Holloway told Today. “She knew I was a dancer and that I was doing beauty pageants and that I was a good kid.”

Holloway added that just before her 18th birthday, she was made aware of her adoptive mom’s kind gesture. And they even went to meet Holloway’s birth mom, an event Holloway that noted was in many ways more emotional for her two moms than it was for her, recalling that both women “had a long, long, long embrace and were both bawling their eyes out.”

As for Holloway, she told Today that she feels no ill will towards her biological mom. Rather, she sees the decision as “an act of love," that set her up for a truly “amazing life.” At the end of their meeting, after the important questions pertaining to family health history and whatnot, all she had to say was “thank you.”

And from the looks of it, she is as happy as ever living life with her adopted parents, who honestly could pass for her biological parents any day.

It's interesting to think about how none of us know our full life story, how many things both bigs and small remain mysteries. But when we are lucky enough to discover hidden truths, we unlock yet another part of ourselves.
