Learning a Second Language Keeps Your Brain Young

Parli Italiano? ¿Hablas Español? Can you speak more than one language? No matter how old you are, it’s not too late to learn. In fact, new research finally shows that learning a second (or third) language as an adult can help slow brain decline.

The benefits of bilingualism are no secret. Previous studies suggest people who regularly speak more than one language show a later onset of dementia and improved mental function. But there was always the pesky problem of correlation vs. causation: Were smarter people simply more likely to learn extra languages? Or were they smarter because they learned extra languages? A recent study from the University of Edinburgh is the strongest evidence yet that, indeed, learning a second language can improve your mental functions—even if you learn the language later in life.

The results come thanks to something called the Lothian Birth Cohort study. In 1947, 1100 11-year-old school children around Edinburgh, Scotland, were given cognitive tests. All of them spoke just one language at the time, but many went on to learn at least one other language as adults, making them (and their test scores) a gold mine for language researchers like Thomas Bak. And because “people of this generation don’t move around that much, it was possible trace them as well,” Bak tells mental_floss.

He and his team tracked down 853 of the original test subjects, now in their early 70s. One-third had learned to speak an additional language since the original test, and 65 of those became bilingual after turning 18. Some learned Gaelic, others learned French in school, or German. Others even traveled to Africa and learned African languages.

Bak gave the same cognitive tests to the original participants to compare their performance with that of their 11-year-old selves. The original scores set a baseline for measuring and predicting mental function: If they performed poorly at age 11, researchers predicted the subjects would also perform relatively poorly at age 73. If their original test scores were high, they would probably be high again at age 73. The results show that “people perform better than you would predict only on the basis of if they learn another language,” says Bak.

This is an important finding, Bak says, because for a long time it was believed that the only time to learn a second language was as a child, when your brain is still nice and sponge-y. This research says even learning it later has positive effects on mental function.

But what is it about language that is so good for our brains? Bak says the act of switching between several languages may give the brain a workout, since you have many more words and meanings to choose from before speaking. He compares it to the physical workout of swimming. “You are using most of your muscles and breathing and so on,” he says. “In being bilingual you’re activating a whole range of different mental functions.”

If you learn three, four, or even five languages, does your brain become stronger with each? Bak says this isn’t clear yet. In theory, the more languages you know, the more mental switches you’ll need to make when speaking, he says, but it’s hard to generalize about something as complicated as language. But there’s no harm in learning as many as possible.

And if you think you’re too old, just remember: our brains are designed for this. “Bilingualism might have been the original state of human communities,” Bak says. “It was more the rule than the exception. The fact we have this ability means in a way our brains are designed to do it.”

Sploot 101: 12 Animal Slang Words Every Pet Parent Should Know

For centuries, dogs were dogs and cats were cats. They did things like bark and drink water and lay down—actions that pet parents didn’t need a translator to understand.

Then the internet arrived. Scroll through the countless Facebook groups and Twitter accounts dedicated to sharing cute animal pictures and you’ll quickly see that dogs don’t have snouts, they have snoots, and cats come in a colorful assortment of shapes and sizes ranging from smol to floof.

Pet meme language has been around long enough to start leaking into everyday conversation. If you're a pet owner (or lover) who doesn’t want to be out of the loop, here are the terms you need to know.

1. SPLOOT

You know your pet is fully relaxed when they’re doing a sploot. Like a split but for the whole body, a sploot occurs when a dog or cat stretches so their bellies are flat on the ground and their back legs are pointing behind them. The amusing pose may be a way for them to take advantage of the cool ground on a hot day, or just to feel a satisfying stretch in their hip flexors. Corgis are famous for the sploot, but any quadruped can do it if they’re flexible enough.

2. DERP

Unlike most items on this list, the word derp isn’t limited to cats and dogs. It can also be a stand-in for such expressions of stupidity as “duh” or “dur.” In recent years the term has become associated with clumsy, clueless, or silly-looking cats and dogs. A pet with a tongue perpetually hanging out of its mouth, like Marnie or Lil Bub, is textbook derpy.

3. BLEP

If you’ve ever caught a cat or dog poking the tip of its tongue past its front teeth, you’ve seen a blep in action. Unlike a derpy tongue, a blep is subtle and often gone as quickly as it appears. Animal experts aren’t entirely sure why pets blep, but in cats it may have something to do with the Flehmen response, in which they use their tongues to “smell” the air.

4. MLEM

Mlems and bleps, though very closely related, aren’t exactly the same. While blep is a passive state of being, mlem is active. It’s what happens when a pet flicks its tongue in and out of its mouth, whether to slurp up water, taste food, or just lick the air in a derpy fashion. Dogs and cats do it, of course, but reptiles have also been known to mlem.

5. FLOOF

Some pets barely have any fur, and others have coats so voluminous that hair appears to make up most of their bodyweight. Dogs and cats in the latter group are known as floofs. Floofy animals will famously leave a wake of fur wherever they sit and can squeeze through tight spaces despite their enormous mass. Samoyeds, Pomeranians, and Persian cats are all prime examples of floofs.

6. BORK

According to some corners of the internet, dogs don’t bark, they bork. Listen carefully next time you’re around a vocal doggo and you won’t be able to unhear it.

7. DOGGO

Speaking of doggos: This word isn’t hard to decode. Every dog—regardless of size, floofiness, or derpiness—can be a doggo. If you’re willing to get creative, the word can even be applied to non-dog animals like fennec foxes (special doggos) or seals (water doggos). The usage of doggo saw a spike in 2016 thanks to the internet and by the end of 2017 it was listed as one of Merriam-Webster’s “Words We’re Watching.”

8. SMOL

Some pets are so adorably, unbearably tiny that using proper English to describe them just doesn’t cut it. Not every small pet is smol: To earn the label, a cat or dog (or kitten or puppy) must excel in both the tiny and cute departments. A pet that’s truly smol is likely to induce excited squees from everyone around it.

9. PUPPER

Like doggo, pupper is self-explanatory: It can be used in place of the word puppy, but if you want to use it to describe a fully-grown doggo who’s particularly smol and cute, you can probably get away with it.

10. BOOF

We’ve already established that doggos go bork, but that’s not the only sound they make. A low, deep bark—perhaps from a dog that can’t decide if it wants to expend its energy on a full bark—is best described as a boof. Consider a boof a warning bark before the real thing.

11. SNOOT

Snoot was already a dictionary-official synonym for nose by the time dog meme culture took the internet by storm. But while snoot is rarely used to describe human faces today, it’s quickly becoming the preferred term for pet snouts. There’s even a wholesome viral challenge dedicated to dogs poking their snoots through their owners' hands.

12. BOOP

Have you ever seen a dog snoot so cute you just had to reach out and tap it? And when you did, was your action accompanied by an involuntary “boop” sound? This urge is so universal that boop is now its own verb. Humans aren’t the only ones who can boop: Search the word on YouTube and treat yourself to hours of dogs, cats, and other animals exchanging the love tap.

From Camreigh to Kayzleigh: Parents Invented More Than 1000 New Baby Names Last Year

Look out Mercedes, Bentley, and Royce—there's a new car-inspired name in town. The name Camreigh was recorded for the first time in the U.S. last year, according to Quartz’s take on data released by the U.S. Social Security Administration.

The name was given to 91 babies in 2017, making it the most popular of the 1100 brand-new names that cropped up last year. However, the Social Security Administration only listed names that had been given to at least five babies in 2017, so it's possible that some of the names had been invented before 2017.

An alternate spelling, Kamreigh, also appeared for the first time last year, as did Brexleigh, Kayzleigh, Addleigh, Iveigh, Lakeleigh, and Riverleigh. Swapping out “-y” and “-ey” for “-eigh” at the end of a name has been a growing trend in recent years, and in 20 years or so, the workforce will be filled with Ryleighs, Everleighs, and Charleighs—names that all appeared on a list of the 500 most popular names in 2017.

Following Camreigh, the second most popular new name, appearing 58 times, was Asahd. Meaning “lion” in Arabic, Asahd was popularized in 2016 when DJ Khaled gave his son the name. The American DJ is now attempting to trademark the moniker, which is an alternate spelling of Asad and Assad.

Other names that were introduced for the first time include Iretomiwa (of Nigerian origin) and Tewodros (Ethiopian). The name Arjunreddy (given 12 times) possibly stems from the 2017 release of the Indian, Telugu-language film Arjun Reddy, whose title character is a surgeon who spirals out of control when he turns to alcohol and drugs.

Perhaps an even bigger surprise is the fact that 11 babies were named Cersei in 2017, or, as Quartz puts it, "11 fresh-faced, sinless babies were named after the manipulative, power-hungry, incestuous, helicopter parent-y, backstabbing character from Game of Thrones."

Below are the top 20 most popular new names in 2017.

1. Camreigh
2. Asahd
3. Taishmara
4. Kashdon
5. Teylie
6. Kassian
7. Kior
8. Aaleiya
9. Kamreigh
10. Draxler
11. Ikeni
12. Noctis
13. Sayyora
14. Mohana
