Newly Invented Glass Would Let Cracked Smartphone Screens "Heal" Themselves

The solution to cracked smartphone screens may not come from stronger glass or less-clumsy owners. Based on new research published in Science, it's possible that the phones of the future will feature glass that "heals" itself when shattered. A version of this new type of glass has been developed by researchers in Japan, The Guardian reports.

Graduate student Yu Yanagisawa invented the material by accident while attempting to make a glue. The substance he came up with behaved strangely: If he made cracks in the surface, he could make the fissures disappear after pressing them together for 30 seconds at regular room temperature (about 70°F). He also found that the material reverted back to its original strength after being left alone for a few hours.

The polymer, called polyether-thioureas, isn't the first invention capable of healing itself. Scientists have already come up with self-repairing rubber, plastic, and concrete, and earlier this year Motorola patented a display that fixes its own cracks when heated. But according to the study, this is the first hard material whose self-healing properties function at room temperature. Thanks to a special hydrogen-bond pattern, the polymer offers the same robust protection as traditional glass without the irreparability.

It's easy to see how the technology could be a game-changer for phone manufacturers. According to a survey by Motorola, half of people around the world have cracked at least one smartphone screen in their lives. One possible reason that companies like Apple prefer glass for their screens over soft, durable plastic is that glass is more easily recycled. Yanagisawa believes his new polymer could be an even more sustainable alternative, as it could lead to fewer broken screens and phones being tossed in the trash.

Swear Off Toilet Paper With This Bidet Toilet Seat That's Easy to Install and Costs Less Than $100

Tushy

The recent coronavirus-related toilet paper shortage has put the spotlight on the TP-less alternative that Americans have yet to truly embrace: the bidet.

It's not exactly a secret that toilet paper is wasteful—it's estimated to cost 437 billion gallons of water and 15 million trees to produce our yearly supply of the stuff. But while the numbers are plain to see, bidets still aren't common in the United States.

Well, if price was ever the biggest barrier standing in the way of swearing off toilet paper for good, there's now a cost-effective way to make the switch. Right now, you can get the space-saving Tushy bidet for less than $100. And you'll be able to install it yourself in just 10 minutes.

What is a Bidet?

Before we go any further, let’s just go ahead and get the awkward technical details out of the way. Instead of using toilet paper after going to the bathroom, bidets get you clean by using a stream of concentrated water that comes out of a faucet or nozzle. Traditional bidets look like weird toilets without tanks or lids, and while they’re pretty uncommon in the United States, you’ve definitely seen one if you’ve ever been to Europe or Asia.

That said, bidets aren’t just good for your butt. When you reduce toilet paper usage, you also reduce the amount of chemicals and emissions required to produce it, which is good for the environment. At the same time, you’re also saving money. So this is a huge win-win.

Unfortunately, traditional bidets are not an option for most Americans because they take up a lot of bathroom space and require extra plumbing. That’s where Tushy comes in.

The Tushy Classic Bidet Toilet Seat.

Unlike traditional bidets, the Tushy bidet doesn’t take up any extra space in your bathroom. It’s an attachment for your existing toilet that places an adjustable self-cleaning nozzle at the back of the bowl, just underneath the seat. But it doesn’t require any additional plumbing or electricity. All you have to do is remove the seat from your toilet, connect the Tushy to the clean water supply behind the toilet, and replace the seat on top of the Tushy attachment.

The Tushy has a control panel that lets you adjust the angle and pressure of the water stream for a perfect custom clean. The nozzle lowers when the Tushy is activated and retracts into its housing when not in use, keeping it clean and sanitary.

Like all bidets, the Tushy system takes a little getting used to. But once you get the hang of it, you’ll never want to use toilet paper again. In fact, Tushy is so sure you’ll love their product, they offer customers a 60-day risk-free guarantee. If you don’t love your Tushy, you can send it back for a full refund, minus shipping and handling.

Normally, the Tushy Classic retails for $109, but right now you can get the Tushy Classic for just $89. So if you’ve been thinking about going TP-free, now is definitely the time to do it.

10 Chance Meetings That Changed the World

Some call it fate. Others call it destiny. And some just brush it off as coincidence. But however you view it, life has a funny way of bringing people together at just the right place and time. Check out some of the most random historical encounters we could find—meetings that, had they not happened, would have resulted in a very different world today.

1. Elizabeth Cady Stanton and Susan B. Anthony

The suffrage movement would have looked very different had Elizabeth Cady Stanton and Susan B. Anthony not met on a street corner in 1851. Although both Stanton and Anthony were fierce abolitionists, Stanton got involved in suffrage earlier. She launched the First Women’s Rights Convention in 1848 as a reaction to being denied a seat at the World’s Anti-Slavery Convention because she was a woman. Similarly, Anthony, who was born into a family of abolitionists, turned her sights toward suffrage after being unable to speak at a temperance convention. Still, their meeting was entirely coincidental.

After Anthony traveled to Seneca Falls, New York—where Stanton lived—for an antislavery meeting, she and her friend Amelia Bloomer ran into Stanton on the street. Bloomer, a mutual friend of both, introduced them, and the two formed a near-immediate friendship. Because Stanton was a busy wife and mother, she needed someone to be the voice of the suffrage movement and to deliver her speeches on the road. That person became Susan B. Anthony. Together, this powerful duo would go on to launch a suffrage newspaper called The Revolution, found the National American Women Suffrage Association, and more—all because they happened to go for a walk at the same time.

2. F. Scott and Zelda Fitzgerald

You would think that the most iconic couple of the 1920s would have met in a speakeasy, or, at the very least, been introduced by some famous author friends. But instead, the couple that embodied the Roaring Twenties met in a pretty ordinary way: At a dance. In July 1918, 21-year-old F. Scott Fitzgerald, then a soldier, was stationed at Camp Sheridan in Montgomery, Alabama, awaiting orders to fight overseas in World War I. Sick of having only his fellow soldiers for company, he decided to attend a nearby country club dance to blow off some steam. It was there he met Zelda Sayre for the first time.

Zelda was already the crown jewel of Montgomery society by that point and wasn’t initially interested in Fitzgerald, an aspiring writer. Still, Fitzgerald pursued the fiercely independent Zelda for two years, and finally convinced her to marry him after his first novel, This Side of Paradise, was picked up by Scribner in 1920. Though their marriage was famously tumultuous, they did inspire each other's work. F. Scott would even wind up lifting lines from Zelda's personal diary and including them in The Great Gatsby

3. Larry Page and Sergey Brin

College tours aren’t normally life-changing—but in the case of Google’s founders, a walk around Stanford ended up changing the course of their careers (and had a pretty big impact on the rest of us). In 1995, Sergey Brin, then a second-year grad student in computer science, volunteered to be a tour guide for prospective students who had just been admitted to the school. By pure chance, Larry Page, an engineering major from the University of Michigan, ended up in his group.

Although the pair didn’t exactly start off as friends (they clashed during the tour and found each other “obnoxious”) it was a meaningful first impression. Several months later, when Page’s dissertation on the World Wide Web turned into a much bigger project involving a prototype search engine, he needed help building the system—which was originally named BackRub but, thankfully, was renamed to Google. The person he chose for the job? Someone who he had come to respect: his former tour guide.

4. Bob Woodward and Mark Felt (a.k.a. Deep Throat)

It turned out to be a simple package that helped turn Bob Woodward from a run-of-the-mill journalist into one of the men responsible for uncovering the most infamous scandal in presidential history. In 1970, Woodward was a lieutenant in his final year of Naval service, and one of his regular duties was to work as a courier delivering packages to the White House. One night, after spending a considerable amount of time in a waiting room for someone to come sign for a package, an older man came out to meet him. Woodward struck up a conversation with the man, and eventually learned that he was Mark Felt, an assistant director of the FBI.

Woodward, eager to advance in his career, asked for Felt’s phone number so that they could stay in touch. He reached out often while he transitioned from a military man to a journalist, with Felt acting as mentor and occasional anonymous source for Woodward's stories. Eventually, Felt would feed Woodward and his partner, Carl Bernstein, the information that helped uncover the Watergate scandal, which would lead to the resignation of President Richard Nixon on August 8, 1974.

5. Frederick Douglass and William Lloyd Garrison

William Lloyd Garrison’s newspaper, The Liberator, was the largest abolitionist publication of its time—and Frederick Douglass just so happened to be a loyal reader. When Douglass heard that Garrison was going to give a speech at an antislavery convention in New Bedford, Massachusetts, in 1841, he decided to attend. But while he was there, a friend coaxed the shy Douglass to give a speech on his life story as a runaway slave in front of the attendees, which he reluctantly agreed to. Garrison, deeply moved by the unexpected speech, realized that Douglass not only had an incredible story—but a talent for speaking, as well.

Douglass's unlikely speech turned into another one two days later at the Massachusetts Anti-Slavery Society’s convention in Nantucket, and Garrison took it upon himself to land Douglass a gig as a lecturer at the Society. He soon became Douglass’s mentor, introducing him to other influential abolitionists and later helping him to get his book published. Although the pair eventually became estranged due to differing interpretations of the Constitution, their early partnership helped Douglass ascend to national recognition, eventually leading to his fateful meeting with Abraham Lincoln in the White House. Not an honor often afforded to former slaves, Douglass spoke with the president about the unfair treatment of black soldiers fighting in the Civil War, leading to a sometimes strained but always respectful relationship between the two until Lincoln's death.

6. Steve Jobs and Steve Wozniak

iPhones, Macbooks, Apple watches, and more possibly wouldn’t exist if it wasn't for ... Bill Fernandez?

Fernandez was a mutual friend of Steve Jobs—whom he'd known since they attended Cupertino Junior High School—and Steve Wozniak, who lived on Fernandez's block. He thought they'd naturally hit it off.

Jobs was visiting Fernandez one day in 1971, and as they took a walk around the block, Fernandez saw Wozniak outside washing his car. He introduced the pair, and pretty soon, Jobs and Wozniak were fast friends themselves.

Jobs and Wozniak began hanging out and eventually started working on projects together. The first was blue boxes for phone phreakers (devices that people used to “hack” phones and make free calls). They quickly moved on to more respectable work, though, after joining the Homebrew Computer Club, a Silicon Valley-based club for computer hobbyists looking to make their own machines. From there, Wozniak built the Apple I in 1976—his first computer kit—and had Jobs help with the marketing. Soon after, the pair would work on the Apple II and formed Apple Computer, Inc. Fernandez would be one of the company's first employees.

7. John Lennon and Paul McCartney

On July 6, 1957, a 15-year-old McCartney attended the annual Woolton Parish Church Garden Fete—not because he was a particularly active member of the church community, but because he hoped to find a girl there. With no girls to be found, he decided to listen to the music instead.

A high school band called The Quarrymen had just managed to squeeze themselves onto the schedule of events that day, and McCartney was immediately impressed by their sound. Once the set was over, McCartney had a mutual friend introduce him to the lead singer, John Lennon, so he could show off his stuff. After seeing McCartney’s (very impressive) guitar skills, Lennon invited him to join the band. And half of the Beatles was born.

8. Henry Ford and Thomas Edison

Thomas Edison was Henry Ford’s personal hero, but he never dreamed that they would become great friends. That all changed in 1896, however, when Ford attended the convention of the Association of Edison Illuminating Companies in Brooklyn, New York. Edison was making his rounds at the event, and, much to Ford’s delight, had a brief conversation with him about his recently invented quadricycle, the first automobile Ford ever designed. (Ford was working at one of Edison's subsidiary companies at this time and had idolized the inventor since he was a boy.)

According to legend, Edison, fascinated by Ford's ingenuity, told him: “You have the thing. Keep at it.” Twelve years later, Ford—who would single out the chance meeting as an important inspiration for his career—introduced the Model T, and he and Edison eventually formed a deep friendship that would last the rest of their lives.

9. Wallis Simpson and Prince Edward

Who knew that a weekend getaway would cause one of the most scandalous relationships in Great Britain’s history? Wallis Simpson, an American expat who came to England in the 1920s, was a social climber eager to rub elbows with only the most elite of British society. Previously married to a navy pilot, she and her second husband, Ernest Simpson, rose quickly through the ranks of the upper crust, and in 1931, they were invited to an exclusive hunting weekend at their friend Lady Thelma Furness’s home.

Lady Furness, who was Prince Edward VIII’s mistress at the time, could never have imagined that introducing Wallis and Prince Edward would doom her own relationship—and all because he and Wallis had a dull conversation about central heating. When Wallis allegedly called him out for essentially being a bore (a social crime of the highest degree), the prince was so enchanted by her feisty cheek that he (eventually) deemed it worthy of abdicating a throne for.

10. Sacagawea and Lewis & Clark

Sacagawea is well-known as explorer Meriwether Lewis and William Clark’s translator during their Corps of Discovery Expedition, which explored the new Louisana Purchase, but the story of how she actually came to join the expedition is even more incredible. A member of the Shoshone tribe, she was kidnapped by a rival tribe, the Hidatsa, when she was a teenager and was brought to their settlement in South Dakota. She was then sold to a French-Canadian fur trader, Toussaint Charbonneau, who already lived with the Hidatsa. She was made to become one of his two wives and soon became pregnant with his child (polygamy was a Hidatsa tradition Charbonneau readily adopted, according to History.com).

By the time Lewis and Clark reached Hidatsa territory in November 1804 and began building their own settlement after establishing friendly contact with the tribe, Sacagawea was six months pregnant. Lewis and Clark met Sacagawea and Charbonneau during their stay and immediately recognized her value as a travel companion—she could speak both Hidatsa and Shoshone, and they could use her language skills to purchase much-needed horses from the Shoshone for the expedition. (She would translate Shoshone into Hidatsa and communicate that to Charbonneau, who would translate the Hidatsa into French and communicate that to a French- and English-speaking member of the Corps.) They waited for Sacagawea to give birth before continuing on their journey, and in 1805, the Corps of Discovery—which now included Sacagawea, Charbonneau, and their newborn son—departed. With Sacagawea's help, they would make it to the Pacific Coast and back with maps, specimens, and important information about the Louisiana Purchase.
