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.

Should a man lose his home because the grass in his yard grew higher than 10 inches? The city of Dunedin, Florida seems to think so.

According to the Institute of Justice, which is representing Jim Ficken, he had a very good reason for not mowing his lawn – and tried to rectify the situation as best he could.

In 2014, Jim's mom became ill and he visited her often in South Carolina to help her out. When he was away, his grass grew too long and he was cited by a code office; he cut the grass and wasn't fined.

France has started forcing supermarkets to donate food instead of throwing it away.

But several years later, this one infraction would come back to haunt him after he left to take care of him's mom's affairs after she died. The arrangements he made to have his grass cut fell through (his friend who he asked to help him out passed away unexpectedly) and that set off a chain reaction that may result in him losing his home.

The 69-year-old retiree now faces a $29,833.50 fine plus interest. Watch the video to find out just what Jim is having to deal with.

The world officially loves Michelle Obama.

The former first lady has overtaken the number one spot in a poll of the world's most admired women. Conducted by online research firm YouGov, the study uses international polling tools to survey people in countries around the world about who they most admire.

In the men's category, Bill Gates took the top spot, followed by Barack Obama and Jackie Chan.

In the women's category, Michelle Obama came first, followed by Oprah Winfrey and Angelina Jolie. Obama pushed Jolie out of the number one spot she claimed last year.

Unsurprising, really, because what's not to love about Michelle Obama? She is smart, kind, funny, accomplished, a great dancer, a devoted wife and mother, and an all-around, genuinely good person.

She has remained dignified and strong in the face of rabid masses of so-called Americans who spent eight years and beyond insisting that she's a man disguised as a woman. She's endured non-stop racist memes and terrifying threats to her family. She has received far more than her fair share of cruelty, and always takes the high road. She's the one who coined, "When they go low, we go high," after all.

She came from humble beginnings and remains down to earth despite becoming a familiar face around the world. She's not much older than me, but I still want to be like Michelle Obama when I grow up.

Her memoir, Becoming, may end up being the best-selling memoir of all time, having already sold 10 million copies—a clear sign that people can't get enough Michelle, because there's no such thing as too much Michelle.

Don't like Michelle Obama? Don't care. Those of us who love her will fly our MO flags high and without apology, paying no mind to folks with cold, dead hearts who don't know a gem of a human being when they see one. There is nothing any hater can say or do to make us admire this undeniably admirable woman any less.

When it seems like the world has lost its mind—which is how it feels most days these days—I'm just going to keep coming back to this study as evidence that hope for humanity is not lost.

Here. Enjoy some real-life Michelle on Jimmy Kimmel. (GAH. WHY IS SHE SO CUTE AND AWESOME. I can't even handle it.)

What will future generations never believe that we tolerated in 2019?

Dolphin and orca captivity, for sure. They'll probably shake their heads at how people died because they couldn't afford healthcare. And, they'll be completely mystified at the amount of food some people waste while others go starving.

According to Biological Diversity, "An estimated 40 percent of the food produced in the United States is wasted every year, costing households, businesses and farms about $218 billion annually."

There are so many things wrong with this.

First of all it's a waste of money for the households who throw out good food. Second, it's a waste of all of the resources that went into growing the food, including the animals who gave their lives for the meal. Third, there's something very wrong with throwing out food when one in eight Americans struggle with hunger.

Supermarkets are just as guilty of this unnecessary waste as consumers. About 10% of all food waste are supermarket products thrown out before they've reached their expiration date.

Three years ago, France took big steps to combat food waste by making a law that bans grocery stores from throwing away edible food.According to the new ordinance, stores can be fined for up to $4,500 for each infraction.

Previously, the French threw out 7.1 million tons of food. Sixty-seven percent of which was tossed by consumers, 15% by restaurants, and 11% by grocery stores.

This has created a network of over 5,000 charities that accept the food from supermarkets and donate them to charity. The law also struck down agreements between supermarkets and manufacturers that prohibited the stores from donating food to charities.

"There was one food manufacturer that was not authorized to donate the sandwiches it made for a particular supermarket brand. But now, we get 30,000 sandwiches a month from them — sandwiches that used to be thrown away," Jacques Bailet, head of the French network of food banks known as Banques Alimentaires, told NPR.

It's expected that similar laws may spread through Europe, but people are a lot less confident at it happening in the United States. The USDA believes that the biggest barrier to such a program would be cost to the charities and or supermarkets.

"The logistics of getting safe, wholesome, edible food from anywhere to people that can use it is really difficult," the organization said according to Gizmodo. "If you're having to set up a really expensive system to recover marginal amounts of food, that's not good for anybody."

Plus, the idea may seem a little too "socialist" for the average American's appetite.

"The French version is quite socialist, but I would say in a great way because you're providing a way where they [supermarkets] have to do the beneficial things not only for the environment, but from an ethical standpoint of getting healthy food to those who need it and minimizing some of the harmful greenhouse gas emissions that come when food ends up in a landfill," Jonathan Bloom, the author of American Wasteland, told NPR.

However, just because something may be socialist doesn't mean it's wrong. The greater wrong is the insane waste of money, damage to the environment, and devastation caused by hunger that can easily be avoided.
