Think there's no such thing as a high-paying, low-stress job? Think again.

With help from career-information expert Laurence Shatkin, Ph.D., we combed through the Occupational Information Network (O*NET), a US Department of Labor database that compiles detailed information on hundreds of jobs, and looked at salary data on the US Bureau of Labor Statistics website to find jobs with that perfect combination of high pay and low stress — and it turns out there are plenty.

O*NET rates the "stress tolerance" for each job on a scale from zero to 100, where a lower rating signals less stress. (Note: We are not saying these jobs are "stress free"– they just tend to rate lower than other professions.)

To rate each job, O*NET looks at how frequently workers must accept criticism and deal effectively with high stress at work.

Here are 25 jobs that pay more than $70,000 a year, on average, and earned a stress tolerance rating of 70 or lower, in order from highest to lowest stress score.

We're less than a week away from the start of the 2016 Summer Olympics from Rio, and officials are scrambling to put on the finishing touches.

The Olympic Village has been called "uninhabitable", though athletes are moving in nonetheless, and a ramp at the sailing venue was destroyed by 10-foot waves. The overall budget has skyrocketed. 

With each passing Olympics, more and more cities around the world are starting to question if hosting the Olympics is worth it.

Most cities simply do not have the infrastructure required to withstand the two-week influx of athletes, coaches, fans, and media members. The money required to build state-of-the-art athletic facilities is soaring, and academic research suggests spending billions on a two-week event is not a wise investment.

In the worst-case scenario for host cities, Olympic venues go unused after the games and become white elephants — total wastes of space and money. We've seen this at a number of different Olympic sites around the world. Of course, the reasons this happens are specific to each country: Sarajevo, for example, suffered from a gruesome war that caused the 1984 Winter Olympic venues to crumble. Nevertheless, these photos from Reuters, Getty Images, and others have become symbolic of the downside of hosting the Olympics.

Will Rio follow a similar path? 

Sarajevo hosted the Winter Olympics in 1984.

One decade later, civil war broke out and ravaged the country.

Some of the Olympic venues were repurposed and used as military facilities.

As Barack and Michelle Obama wind down their time in The White House, it's a good time to take a look at their relationship.

Obama mentions his wife in almost every speech he gives, and often showers her with PDA, even when the cameras are rolling.

Married since 1992, Barack and Michelle Obama have captured our hearts with their love for one another. In February, "The Ellen DeGeneres Show" played a recorded Valentine's Day message from the president to his wife.

"I ObamaCare about you more than you even know," he said.

To celebrate the Obamas, we have collected a few of our favorite photos of their most romantic moments.

Barack and Michelle Obama were married on October 18, 1992. Michelle worked as a Chicago city government as an assistant to the mayor while Barack taught constitutional law at the University of Chicago Law School.

Here's the night where Obama formally announced his campaign for U.S. President in the 2008 election on February 10, 2007.

Campaigning at the Iowa State Fair in 2007, Barack gives his wife a playful kiss.

Still looking for a way to hunt for specific Pokémon in "Pokémon GO"now that PokéVision is dead?

Good news: There is an alternative.

Skiplagged's Pokémon tracker uses Google Maps to show exactly where certain Pokémon are spawning in real time. We tested it, and it works.

Niantic Labs, the creator of "Pokémon GO," has started shutting down sites like PokéVision and other unofficial trackers. So we don't know how long Skiplagged's map will be operational. But it works for now.

Skiplagged is a startup that shows you "hidden" deals on flights and hotels. People who work there are clearly fans of "Pokémon GO" too.

Like PokéVision, you can use Skiplagged's map to see exactly where certain creatures are spawning near a given location. Here's New York City's Central Park:

You can click on a specific Pokémon to see how many seconds are left before it disappears.

First and foremost, college is about getting an education. But it's also about having fun, going out, and making new friends.

Business Insider created a list of schools that best embody this dual principle — the "work hard, play hard" mentality that many students look for.

To find the most intense colleges in the country, we combined four rankings from college information site Niche: colleges with the best academics, smartest students, best Greek life colleges, and top party schools. We eliminated any schools that ranked only for academics or only for social life.

The list runs the gamut from big state schools, such as the University of Texas and the University of Michigan, to Ivies like Dartmouth and Yale.

Take a look at the most intense colleges in America, where students go all out, whether they're studying or partying.

30. Wake Forest University

Location: Winston Salem, North Carolina

Academics: A+

Party Scene: A

"Academics at Wake are impeccable," one student said. "You will get a great education, albeit with a large workload. The workload is manageable, and if you want to actually learn something in college, go here."

Greek life takes over campus on the weekends.

"Greek life dominates the party scene, so usually there is either a frat lounge party or off-campus house party every Friday and Saturday night," one freshman noted.

29. University of Florida

Location: Gainesville, Florida

Academics: A

Party Scene: A+

"A lot of people party — almost every day of the week there's going to be people at the club," one senior said.

There's still plenty of time to study, however.

"I have never been challenged as much in my academics than I have at UF, but being challenged like this is only going to help me in life after college," a junior noted.

28. Tulane University

Location: New Orleans, Louisiana

Academics: A+

Party Scene: A+

"Tulane seamlessly combines social life and academic rigor to provide a great college experience and ensure success after graduation," one sophomore commented.

Other students agree — Tulane students study as hard as they party.

"Most students follow the 'work hard, play hard' model religiously," one freshman reported. "Most students study all day and go out after. People do go out a decent amount during the week, as many of the bars have deals during weeknights." 

"Pokémon GO" might be taking over the world of smartphones, but the adorable pocket monsters can still be found in plenty of other places, too. 

"Pokémon Sun & Moon" is the next big game in the core series of Pokémon role-playing games, and it's coming out on Nintendo 3DS this November. Here are some of the ridiculous new features that were announced for the game this week:

New forms of classic Pokémon

"Pokémon Sun & Moon" takes place in Alola, a tropical, Hawaii-esque region. There are new versions of old Pokémon that can only be found in Alola called Alola Forms, and they're pretty wild.

Exeggutor becomes a long-necked abomination while Vulpix and Ninetails become ice-themed versions of themselves. Sandshrew also switches elements, looking more like an igloo than before.

Plenty of new Pokémon, of course

Obviously, the main appeal of each new Pokémon game is seeing all of the new monsters to collect along your journey. Luckily, "Pokémon Sun & Moon" has those in spades, and they're crazier than ever.

Oricorio is a bird that looks and behaves completely differently based on which of the game's four islands you found it on, with each style being based on a different kind of dance. Minior, on the other hand, is a sentient, floating meteor that can remove its protective outer rock shell in battle, exposing its colorful, fleshy core.

Those are just two examples of the really ridiculous Pokémon that you'll be able to find in the new game.

All-new island trials

Alola is separated into four islands, with each one representing a different type of environment. Your quest will take you from island to island, completing trials for each island's guardian and battling a superpowered Pokémon at the end of each trial.

This is a welcome change of pace from the older Pokémon games, which had players run from town to town, battling gym leaders along the way. We don't know yet if the more traditional gyms will also show up in "Pokémon Sun & Moon" yet, though.

Travel to a new country. This is one of the few times in your life where you’ll have the flexibility to travel this much.

And if you want to see some new places, it's a good idea to learn a new language.

Party somewhere epic, whether that be by the local water tower, or a castle in another part of the world.

Unless you're tracking expenses carefully, it can be hard to tell whether your city's cost of living or your own spending habits are the cause of your financial troubles.

Using the 50-30-20 budgeting rule, for example — in which 50 percent of income covers necessities, 30 percent is for discretionary items and 20 percent is saved — you can quickly determine whether your income is sufficient to cover expenses for living in your city. If it isn't, you might have to cut costs or maybe even move.

GoBankingRates conducted a cost-of-living comparison of the 75 most populous U.S. cities, surveying dollar amounts of living expenses including rent, groceries, utilities, transportation and healthcare. This total, which accounts for necessities, was then doubled to find how much money a single person needs to earn in that city to follow a 50-30-20 budget. This study also compares the total amount of income needed to the actual median household income in each city to see if differences in cost of living are matched by differences in pay.

15 years have passed since Daniel Radcliffe appeared in "Harry Potter and the Sorcerer's Stone" with that lightning-bolt-shaped scar on his forehead.

Since then, he's grown up, defeated Voldemort, and gone on to act in a bunch of other different movies.

The child actors in the "Harry Potter" movies have all transformed. Some of their acting careers have taken off after the series, and others are still trying to figure it out. There's no question, though, that the eight-film series between 2001 and 2011 has changed their lives forever.

Here's what the main child actors looked like when they were first introduced in the "Harry Potter" movie series, and what they look like now.

Daniel Radcliffe was just 11 years old when he started filming 2001's "Harry Potter and the Sorcerer's Stone."

Since finishing the series, he's had an eclectic career, playing everything from a morose doctor in "The Young Doctor's Notebook" to a flatulent corpse in "Swiss Army Man."

In the early "Harry Potter" movies, filmmakers gave Emma Watson Hermione Granger's famously "bushy" hair.

Last year, French photographer Réhahn took a trip to some of Malaysia's most remote islands in the hopes of documenting the lives of the Bajau, the "sea gypsies" who inhabit the area.

Located off the east coast of the Malaysian city of Sabah, the island of Borneo was Réhahn's jumping-off point. From there he visited eight small islands that are many miles removed from civilization.

Some tourists may know this area for its amazing dive sites, but Réhahn saw a different side: tiny villages made up of huts built on stilts in the middle of the ocean.

You can see more of Réhahn's photos on his Facebook page.

Réhahn's journey to the islands was anything but easy. After a flight to Kuala Lumpur, another three-hour flight to Tawau, and an hour-and-a-half bus ride to Semporna, Réhahn set out to find a local who would take him to the remote islands where the Bajau, or "sea gypsies," live.

Tour agencies would only agree to take Réhahn to resorts, and most fishermen he encountered along the waterfront spoke no English. When he was lucky enough to find someone who did, the price they asked for the trip was high.

After spending a night sleeping on the waterfront — a risky move, as there's a history of tourist kidnappings in the area — Réhahn finally met Karim, a Bajau who agreed to take him to the remote islands he was hoping to visit.

I am not an entertainer by any means. I do not own coasters or wine glasses and I'd rather spend a Saturday night figuring out what to do with my sourdough starter discard than playing hostess.

But when I do plan to invite a few friends over for a meal, and those friends have boyfriends, girlfriends, friends, or cousins that they want to bring ... the group size skips from four to eight (or five to ten!) — and suddenly, I'm the planner and executor of a sizable gathering.

Here are the tips — and questions — that have helped me stay sane as an entertaining non-entertainer:

The Menu

1. Plan your menu around your kitchen's constraints.

Do you have a small oven? Two burners, one of which is defunct? A kitchen that can only fit one person? No Dutch oven?

Read through all of the recipes you're considering a couple of days before the party in order to figure out the equipment that you're missing (what can you MacGyver, what can you borrow, what is a dealbreaker) and to conceive of how everything will fit, both literally and timing-wise.

Then rejigger the menu accordingly. It gives me peace of mind to choose recipes with an even split of oven to stovetop to raw. That way, I'm not waiting around to use the oven — I can cook on the stove, or prepare a chopped salad — as one dish bakes. If you will be baking multiple recipes, try to choose the ones that go in at the same temperature (and that both fit in the oven at the same time!).

2. Embrace room temperature dishes, especially those that can sit for a while.

Unless there's some extremely compelling reason to serve a dish that has to be served piping hot or ice cold, I stay away. When you can serve the food at room temperature, you don't have to be as concerned about timing or storage, and you won't be squirreled away in the kitchen, doling out pasta that must be served immediately, while your friends wait at the table.

3. Keep your friends' dietary restrictions and eating preferences in mind.

For me, the bottom line is that I want my friends and family to eat what I make when I'm hosting them. I'm a vegetarian and the menu is all-vegetarian — so that everyone can eat it — and I keep allergies and preferences in mind too (no nuts anywhere; my brother, what a weirdo, doesn't like berry desserts).

Getting rich isn't reserved for a lucky, select few.

"Like most things in life, becoming good at attracting money is no different than becoming good at anything else, be it being a sub-par golfer, losing weight, or mastering a second language,"writes self-made millionaire Steve Siebold, author of "How Rich People Think."

Almost anyone can make it happen— and it often begins with your thoughts, beliefs, and choices. Here are 18 choices the wealthiest people make on a daily basis that most of us fail to emulate.

Rich people choose to be in control of their success.

"Rich people believe, 'I create my life,' while average people think, 'Life happens to me,'" writes T. Harv Eker in "Secrets of the Millionaire Mind."

You have to be in control of your financial life, he emphasizes: "You have to believe that you are the one who creates your success, that you are the one who creates your mediocrity, and that you are the one creating your struggles around money and success. Consciously or unconsciously, it's still you."

Rich people choose to think big.

If not you, then who? That's how rich people think, Eker writes: "Big thinking and big actions lead to having both money and meaning."

"Most people choose to play small," he continues. "Why? First, because of fear. They're scared to death of failure and they're even more frightened of success. Second, people play small because they feel small. They feel unworthy. They don't feel they're good enough or important enough to make a real difference in people's lives."

As Siebold writes, "Expect to make more money. For this one you have to think big. $100,000, $500,000, or why not $1 million?"

Rich people choose to commit to attaining wealth.

Rather than wanting to be rich, wealthy people consciously commit to being rich.

"Getting rich takes focus, courage, knowledge, expertise, 100% of your effort, a never-give-up attitude, and of course a rich mindset," writes Eker. "If you are not fully, totally, and truly committed to creating wealth, chances are you won't."

The rich are able to fully commit because they have precise goals and a clear vision.

"The number one reason most people don't get what they want is that they don't know what they want," he continues. "Rich people are totally clear that they want wealth. They are unwavering in their desire ... As long as it's legal, moral, and ethical, they will do whatever it takes to have wealth."

Self-driving cars may not be available for the masses yet, but automakers are already decking out their newer vehicles with some pretty innovative technologies. 

We've compiled a list of some of the most high-tech features to look for next time you are in the market for a new car. It should be noted that some of these features are very new and only available in higher-end cars for now, but we expect it won't be long before most of this technology becomes mainstream.

Vehicle-to-vehicle communication

Vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication is basically exactly what it sounds like. It's a type of communication technology that lets cars talk to other vehicles, as well as surrounding infrastructure like traffic lights. 

Why is this important? Because as cars become more autonomous they will need to be able to communicate with other cars on the road in order to operate more safely.

In the more near-term, though, V2V and V2I lets cars share vital information to help human drivers. For example, the 2017 Mercedes E-Class uses V2V communication to relay data about traffic, climate conditions, and other critical information about the road ahead to other Mercedes vehicles on the road. 

Bluetooth connectivity

Bluetooth connectivity is becoming more popular in newer vehicles — and for good reason, too. Bluetooth not only lets you seamlessly begin playing your music from your phone in your car, but it also enables all kinds of other fancy new features. 

For example, in GM's Chevrolet Bolt, which is slated to roll out by the end of this year, Bluetooth connectivity lets the car automatically detect the users smartphone. This lets you stay connected to the vehicle at all times via the car's app. Owners can do things like check the car's charge, start the vehicle, and pre-condition the cabin. 

Volvo also plans to use Bluetooth connectivity to replace your keys with your smartphone. Basically, the car would detect your smartphone via Bluetooth and unlock your vehicle. The Swedish company has plans to make this feature available in at least one of its vehicles during 2017. 

WiFi and LTE 4G connectivity

More automakers are beginning to offer WiFi and LTE 4G connectivity in their newer vehicles. However, you'll still have to pay for whatever data plan you opt for. 

WiFi and LTE 4G basically turns your car into a hotspot, allowing for you to connect several devices to the network.  This means passengers can easily stream music, video, and surf the web without having to worry about killing the battery of your mobile device.

Everybody judges.

Within a few seconds of seeing someone — whether it's on a date or at the grocery store — we decide a number of things about them, from how smart they are to how likely they are to commit a crime.

Surprisingly, our first impressions can be remarkably accurate in some instances. In others, they can be wildly off-base.

Here are a few of the things that we determine about people based on how they look.

DON'T MISS: A common belief about working out might be bogus — and it's good news for anyone trying to tone up

If you're attractive, people assume you have other positive traits as well.

Thanks to a phenomenon that social psychologists call "the halo effect," we tend to assume that good-looking people possess other positive qualities aside from their looks, such as intelligence and commitment.

Daniel Hamermesh, a University of Texas psychologist who studies beauty in the workplace, found that, among other things, this cognitive bias means good looking people tend to get paid more. 

Similarly, in a study of male undergrads who were asked to evaluate an essay written by an unnamed female peer, the participants judged the writer and her work more favorably when they were shown a photo of an attractive woman whom they believed to be the writer, as opposed to when they were shown a photo of an unattractive woman or no photo at all.

People can also get a surprisingly accurate read of your personality from a photo.

People can tell a surprising amount about your personality from your portrait. 

In a 2009 study, researchers showed participants the photos of 123 undergrads from the University of Texas at Austin in which the undergrads either were told to have a neutral expression or were allowed to pose however they wanted.

No matter what position they took, the viewers were better than chance at judging the following: how extroverted they were, how high their self-esteem was, how religious they were, how agreeable they were, and how conscientious they were.

People use facial clues about your height to judge your leadership abilities.

In 2013, a group of psychologists, neuroscientists, and computer scientists from Europe and the US had a small group of participants look at portraits of 47 white men and 83 white women and evaluate them first on their height and next on their ability to lead. 

The researchers found that people used factors in the photos like gender and face length to make guesses about people's height, and then used these same factors when they judged their leadership qualities. Faces that appeared to belong to taller people were rated as belonging to better leaders.

Most friendships develop so naturally that you don't even realize how or when they started.

Sometimes, though, you want to make an effort to befriend a new acquaintance or become a better friend to existing pals.

To help you out on that front, we scoured the psychological research to find science-backed strategies to get people to like you.

Read on to find out how to develop better relationships faster.

This is an update of an article originally written by Maggie Zhang.

SEE ALSO: 12 things you're doing that make people dislike you immediately

1. Copy them

This strategy is called mirroring, and involves subtly mimicking the other person's behavior. When talking to someone, try copying their body language, gestures, and facial expressions.

In 1999, New York University researchers documented the "chameleon effect," which occurs when people unconsciously mimic each other's behavior, and that mimicry facilitates liking.

Researchers had 78 men and women work on a task with a partner, who was really a confederate working for the researchers. The partners engaged in different levels of mimicry, while researchers secretly videotaped the interactions. At the end of the interaction, the researchers had participants indicate how much they liked those partners.

Sure enough, participants were more likely to say that they liked their partner when their partner had mimicked their behavior.

2. Spend more time around them

According to the mere-exposure effect, people tend to like things that are familiar to them.

Knowledge of this phenomenon dates back to the 1950s, when MIT researchers discovered that college students who lived closer together in housing projects were more likely to be friends than students who lived farther apart.

This could be because students who live close by can experience more passive, day-to-day interactions with each other, such as greeting each other in the common room or kitchen. Under certain circumstances, those interactions can develop into full-fledged friendships.

More recently, psychologists at the University of Pittsburgh had four women pose as students in a university psychology class. Each woman showed up in class a different number of times. When experimenters showed male students pictures of the four women, the men demonstrated a greater affinity for those women they'd seen more often in class — even though they hadn't interacted with any of them.

Taken together, these findings suggest that simply spending more time with people can make them like you more. Even if you don't live near your friends, try sticking to a steady routine with them, such as going out for coffee every week or taking a class together.

3. Compliment other people

People will associate the adjectives you use to describe other people with your personality. This phenomenon is called spontaneous trait transference.

One study found that this effect occurred even when people knew certain traits didn't describe the people who had talked about them.

According to Gretchen Rubin, author of books including "The Happiness Project,""whatever you say about other people influences how people see you."

If you describe someone else as genuine and kind, people will also associate you with those qualities. The reverse is also true: If you are constantly trashing people behind their backs, your friends will start to associate the negative qualities with you as well.

Like most professions, finance has a language of its own. If you’re not part of the club (and even when you are), it’s easy to get the lingo wrong. And that can lead to very expensive mistakes.

To help you avoid that, what follows are some of the most frequently misused words in finance… and what they really mean.

Volatility

What People Think It Means:Volatility is commonly mistaken for “uncertainty.” Many people use the two words interchangeably. Volatility is also often framed as a bad thing. Look out for the CNBC talking head muttering – with a stricken look on his face – about how there’s “too much volatility” in markets just now.

What It Really Means: Volatility is just a way to measure the change in the price of an investment over a particular period of time. Whether stocks are going up or down, the amount they move either way is the stock’s volatility.

In the graphs above, both Company A and B have an average share price of $30. But company A has bigger price swings, so it is the more volatile of the two.

If a stock has low volatility, it means it doesn’t make extreme moves beyond its average price. If it is has a lot of volatility, it means the price swings are bigger. But these movements are simply short term. For assets held over a longer period of time, these day-to-day movements have little impact.

Cheap / Expensive Stock

Cheap/expensive stock

What People Think It Means: Some investors look at the price of a stock and make a declaration about whether it’s “cheap” or “expensive”. In this world, shares of consumer electronics giant Apple (traded on the NYSE, ticker: AAPL), which trade at around US$104 per share, are “expensive.” And shares of office supplies store Office Depot (ticker: ODP), which trade at around US$3.50/share, are “cheap.”

What It Really Means: The price of a stock has nothing to do with whether it’s cheap or expensive. When financial professionals talk about cheap and expensive stocks, they are referring to a stock’s valuation. Valuation is often measured using ratios like the price-to-earnings ratio (P/E). This compares a company’s share price to how much money the company makes.

In this case, Apple’s current P/E is 12. And Office Depot is barely profitable, and sports a P/E of 345. Apple shares are cheap – and Office Depot shares are nosebleed expensive, based on current earnings. Price and value are not necessarily related.

Median vs. Average (or mean)

What People Think It Means: There’s an important difference between median and average (which is usually the “mean”). Both median and mean refer to a midpoint in a series of numbers. But the way they’re calculated is very different.

What It Really Means:  Let’s say there are 7 people in a classroom – 6 kids and one teacher. Here is a list of their ages:

5, 6, 6, 7, 7, 8, 36

The average (mean) age of everyone in the classroom is calculated by adding all the ages, and dividing by the number of people. So the sum of the ages is 75… and divided by 7 results in an average age of 10.7.

Of course, the teacher’s age skews the results. In this case, the mean isn’t representative of the age of everyone in the room. Six of the seven people in the room are younger than the average age.

A more accurate indicator is the median age. The median is calculated by arranging the values from lowest to highest and picking the one in the middle – 7 years. So, the median age is 7.

Knowing the difference between the two helps you understand economic and other data. For example, in many countries, the average (mean) household income is a lot higher than the median, because the average is skewed by the very wealthiest households. The median is much more representative, because when incomes are listed from lowest to highest it’s the number in the middle.

In a sense we're all amateur psychologists — we've got our own first-hand experience at being human, and we've spent years observing how we and others behave in different situations.

This intuition fuels a "folk psychology" that sometimes overlaps with findings from scientific psychology, but often does not.

Some erroneous psychological intuitions are particularly widely believed among the public and are stubbornly persistent. This post is about 10 of these myths or misconceptions.

It's important to challenge these myths, not just to set the record straight, but also because their existence can contribute to stigma and stereotypes and to misinformed public policies in areas like education and policing.

1) We learn more effectively when taught via our preferred "learning style."

This is the idea that we each learn better when we're taught via our own favored modality, such as through visual materials, listening or doing.

A recent survey of British teachers found that over 96% believed in this principle. In fact, psychology research shows consistently that people do not learn better when taught via their preferred modality, and that instead the most effective modality for teaching usually varies according to the nature of the material under study.

There are also issues around defining learning styles and how to measure them. Most published scales for measuring learning styles are unreliable (they produce different results on each testing), and they often fail to correlate with people's actual learning performance.

2) Human memory is like a recording of what happened.

The metaphor of memory as a recording is inappropriate because it implies an unrealistic level of accuracy and permanence.

Our memories actually represent a distorted version of what happened, and they change over time.

And yet a survey of nearly 2,000 people from a few years ago found that 63% believed "memory works like a video camera". This misunderstanding fuels related misconceptions, for example around the trustworthiness of eye-witness testimony. For example, many judges and police believe that the more confident a witness is in their memory, the more accurate they are likely to be, even though psychology research shows that confidence and accuracy are not correlated or only weakly correlated.

3) Violent offenders usually have a diagnosis of mental illness.

When people with mental health problems commit violent crimes, the media takes a disproportionate interest. No wonder that surveys show that most of the public believe that people with mental illness are inherently violent.

In fact, as Scott Lilienfeld and his colleagues explain in the "50 Great Myths of Popular Psychology," the evidence suggests that at least 90% of people with mental illness do not commit violent acts, and the overwhelming majority of violent offenders are not mentally ill.

Some patients with specific conditions (such as command-based hallucinations "telling them" to commit acts) are at increased risk, but actual acts of violence are rare.

A telling meta-analysis from 2011 concluded that 35,000 high-risk patients with a diagnosis of schizophrenia would need to be permanently watched or incarcerated to prevent one killing of a stranger by a patient.

Warning: Spoilers ahead for "Harry Potter and the Cursed Child."

J.K. Rowling's latest published work is the full play script for "Harry Potter and the Cursed Child," a stage production co-authored by Rowling, Jack Thorne, and John Tiffany. The story follows Harry Potter's youngest son Albus and his best friend Scorpius Malfoy as they mess with time travel and interact with characters both old and a new. 

While reading through the script, we found several moments and lines that were references to scenes or events from the original seven "Harry Potter" books. Scroll down for a look at the fan-service moments we spotted.

Harry gives his young daughter, Rose, the exact same advice Mrs. Weasley gave him in "Sorcerer's Stone."

In the opening scene of "Cursed Child," Harry and Ginny coach their youngest children (Albus and Lily) before they walk through the magical Platform 9 ¾ for the first time. While doing so, they use the exact same words Mrs. Weasley said to Harry when he needed to access the Hogwarts Express for the first time. 

"Not to worry," Mrs. Weasley told Harry in the first book. "All you have to do is walk straight at the barrier between platforms nine and ten. Don't stop and don't be scared you'll crash into it, that's very important. Best do it at a bit of a run if you're nervous."

And here's the dialogue from "Cursed Child."

"All you have to do is walk straight at the wall between platforms nine and ten," Ginny tells Lily. "Don't stop and don't be scared you'll crash into it, that's very important," Harry chimes in right after. "Best do it at a bit of a run if you're nervous."

Professor McGonagall reports that two ingredients used for making Polyjuice Potion were stolen from Hogwarts.

In Act One, Scene 12 of "Cursed Child," now Minister of Magic Hermione Granger asks a gathered group of people if they've noticed anything strange lately. 

"It did look like the potions stores had been interfered with when we returned from summer break, but not a huge amount of ingredients were missing, some Boomslang skin and lacewing flies, nothing on the Restricted Register," McGonagall reveals. "We put it down to Peeves."

Diehard "Harry Potter" fans would have immediately realized something fishy was up. Boomslang skin and lacewing flies are two of the ingredients needed to brew a Polyjuice Potion, as explained by Hermione in "Chamber of Secrets."

Later it's revealed that Delphi, the daughter of Lord Voldemort, has made polyjuice potion to fulfill her dastardly plan. She must have been sneaking into Hogwarts long before Albus and Scorpius realized.

There's an implied role-reversal when it comes to Hermione and Harry's magical abilities.

After taking the Polyjuice potion, Delphi transforms into Hermione and Scorpius takes the form of Harry Potter. When trying to break into the real Hermione's office, Scorpius comes to the rescue. Delphi (disguised as Hermione) tries and fails to pull open the door, using physical forces instead of magic. Then Scorpius (disguised as Harry) says: "Stand back. Alohomora!"

This is an odd reversal of what happened between the real Harry and Hermione in "Sorcerer's Stone." When Harry, Ron, Hermione, and Neville are on the run from Filch, they encounter a locked door. Harry and Ron panic and can't get into the room, but Hermione comes to the rescue.

"Oh, move over," Hermione snarled. She grabbed Harry's wand, tapped the lock, and whispered, "Alohomora!"

When it comes to working at a startup, there are a lot of truths that people rarely talk about. 

Startup life has become shrouded in myth. People think it's a shortcut to the American Dream, a get-rich-quick path.

But for a lot people, startup life is far harsher and more complicated.

What you've heard: You have to "win" an insanely difficult interview process.

What's really true: yes most startups will want you to prove competence for any technical job. But many hot startups do not put their interviews through the wringer.

For instance, startups like Spotify, 23andme, even Snapchat are known to have interview processes that rate as "average" rather than "hard."

What you've heard: To get a job at a cool startup, you have to be a "culture fit."

In the Arctic Ocean, halfway between mainland Norway and the North Pole, lies Ny-Ålesund, the most northerly settlement in the world.

Once a mining town, this island town on the Norwegian Svalbard archipelago is now home to the largest permanent laboratory for modern arctic scientific research in the world. Researchers living here conduct a number of environmental and earth science studies all year round. 

To keep the area surrounding the town largely untouched, access is extremely limited — only scientists and employees of the station are allowed. But photojournalist Anna Filipova was granted access to this remote research station.

While this wasn’t the first arctic place that Filipova has visited and photographed — she has spent much of her career working on projects above the arctic circle — it is certainly the most northern spot in which she has ever worked, being located above the 79th parallel.  And this barren landscape was also one of the most wild places she had ever been to.

“It was with surprise and trepidation that I learned that I must pass a firearms safety course in order to venture out of the settlement in case of an encounter with a polar bear,” Filipova told Business Insider. Polar bears live and breed in Svalbard, according to the Norwegian Polar Institute, and in the summer, bears sometimes wander close or even into the settlement. “The community has a rule that no one can lock the doors of any building in case a bear appears inside the settlement and there is an urgent need for refuge.”

But despite the harsh environment and risk of polar bears, Filipova arrived home from Ny-Ålesund with the stunning photographs of her series "Research at the End of the World." Here are just a few of these images.

“The Arctic is one of the most fascinating places on earth, but also one of the most endangered,” Filipova said. “It is constantly moving and shifting, melting, reforming, appearing and disappearing.”

This is why the town of Ny-Ålesundit is such a prime location for scientists to observe and study post-global warming conditions. Even though the town is remote and far from human civilization, it is still threatened by polluted air from Europe and North America that is brought by atmospheric circulation.

“From the day I arrived, I was immediately fascinated,” Filipova said. “Everything in the settlement is designed to identify, assess, and track changes within the environment.”
