Before January 2010, Americans were only allowed to visit North Korea during the country's Mass Games, a synchronized performance that takes place in the late summer and early fall.

But now Americans are welcome to visit the country whenever they please, so long as they go as part of an official guided tour endorsed by the state-run Korea International Travel Company.

And despite the US Department of State's travel warning for North Korea, Americans are making the trip.

We did some of our own research, including taking a look at a Quora thread that asked "What are some things I should know before going to North Korea?" to find out what travelers who are planning a trip to the notoriously strict country should keep in mind.

1. Enroll in the state department's smart traveler enrollment program.

The US Department of State issued a travel warning for North Korea in April. While Americans can still safely travel to the country, there are precautions that the state department recommends taking before visiting. One of them is to enroll in the department's smart traveler enrollment program.

This program connects travelers with the US Embassy in Beijing and allows the State Department to email visitors any safety and security updates. However, it's important to keep in mind that you might not always have access to email while visiting certain parts of North Korea.

2. You'll be visiting the country on an official tour with a guide and a driver.

Pretty much the only — and safest — way for Americans to visit North Korea is to go on a tour accompanied by a driver and a guide who are both North Korean. According to the US Department of State, visiting the country alone can be regarded by North Korean security personnel as espionage.

3. Bring a gift for your guide and driver.

Instead of just tipping your guide and driver, most Quora users agree that it's customary to provide them with an actual gift. Quora user Arianne Farah suggests a bottle of alcohol for males and brand-name makeup for females. Farah says drivers will always be male, whereas guides can be male or female. 

4. Ask before taking pictures.

According to Quora user Mandy Raasch, taking pictures is almost always allowed, except at military bases and construction sites. However, most other Quora users recommend asking your guide before snapping a photo, just to be safe. Taking this extra step will help to assure your guide that you're trustworthy, which will likely lead to more leeway for you during the rest of the trip, says Quora user Jordan Harbinger.

5. Upload your pictures to your laptop before leaving the country.

Although you'll most likely be allowed to take photos while touring North Korea, Raasch says that chances are, when you leave the country, someone will ask to check the photos on your camera or phone. In order to avoid losing your pictures forever, make sure to upload them onto your laptop (if you have one with you) before leaving the country.

6. Don't expect the locals to speak English.

Raasch says that while it's safe to stop and talk to locals throughout your trip, keep in mind that most of them won't speak English. Trying to communicate with anyone besides your guide, driver, or fellow tour members will be challenging.

7. Don't bring any religious or political paraphernalia.

All Quora users who contributed to the conversation agreed that bringing anything with a religious or political message is not a good idea. Make sure to leave your Bible at home, and don't wear anything that's religious or political in nature. Your best bet when visiting North Korea is to enjoy the trip, follow your guide, and not try to implement any sort of change.

8. Bow to any statues your guide tells you to.

According to Raasch, there are a number of statues in North Korea in front of which visitors are required to bow. It's a way to pay respect to the country's leaders, and even if you don't agree with it or even comprehend it, it's best to just comply. If you don't, you won't be punished, but your guide will be.

9. Bring earplugs.

Pyongyang, North Korea's capital and the largest city in the country, will most likely be on your itinerary when visiting the country. Farah recommends bringing earplugs for your stay, since the city is loud and there will be constant propaganda on TV no matter where you go.

NOW WATCH: North Korea stages a massive military parade — and they say they're ready for war with 'US imperialists'

As Freebirds revs up for expansion, it’s doing so with an updated design.

The 95-unit Austin-based chain debuted its new prototype last week, with a new location in Castle Hills, Texas, reports Nation’s Restaurant News.

The company called the new design “modern industrial farmhouse” in a blog post about the location. It utilizes many features that have become popular at various trendy fast-casual chains, including digital menu boards, a reclaimed wood wall, and an open kitchen.

“We’ve come to realize that our culinary creations speak louder than our decor and our new design best supports our belief that great people deserve great food — and a great atmosphere to enjoy their meal in,” reads the company blog post on the new design.

The new prototype is a part of Freebird’s plan for growth, with all future restaurants incorporating the new look. Locations in Temple, Texas and Nashville, Tennessee are slated to open with the next design next year, reports Nation’s Restaurant News.

Freebirds has been serving up “Chipotle-style” burritos before Chipotle was even founded, using a similar fast-casual customizable model.

The menu includes customizable bowls, burritos, salads, nachos, and quesadillas, with fillings like steak, carnitas, chicken, and Tempeh Calabacitas.

The company was founded in 1987 in California, and today has locations in seven states in the south and western US.

In 2007, private investment company Tavistock Group purchased Freebirds. Tavistock Group owns a number of small restaurant chains, including Abe & Louie’s, Cafe del Rey, and Joe’s American Bar & Grill, as well as investments including real estate, sports institutes, and energy companies.

There's no shortage of livestreaming apps, but there's one that teens are clamoring to: YouNow.

YouNow's founder, Adi Sideman, told us earlier this year that 70% of YouNow's users are under the age of 24 and that the platform has 100 million user sessions a month, with about 150,000 broadcasts daily.  It's the 34th most popular social networking app in the world right now, according to App Annie.

The four-year-old streaming startup also recently raised a $15 million round of funding.

The interaction between performers and their audiences is what sets YouNow apart from other buzzy livestreaming services such as Periscope or Meerkat. The average mobile session length on YouNow is about six minutes. The average mobile broadcast length is about 18 minutes.

If you still can't quite wrap your head around what YouNow is, Sideman put it best:

"It's a global platform for self-expression," he said. "It's like YouTube, but live. The secret sauce is that it's all about the audience. And the audience feels like even though it's a one-to-many, it feels like a one-to-one interaction."

We've put together a quick guide on how to use YouNow. It's fairly straightforward and intuitive — moreso than apps like Snapchat — but it's still riddled with nuances a first-time user wouldn't necessarily pick up on.

SEE ALSO: Teens are going crazy for YouNow, a livestreaming app with 100 million monthly user sessions

This is what you see when you first open YouNow. Last year, Vine star Shawn Mendes released a single on YouNow. Tumblr star and internet personality Tyler Oakley raised half a million dollars on the crowdfunding website Prizeo for The Trevor Project, a charity that raises awareness for LGBT youths at risk of suicide, and linked to his YouNow account in a sort of modern-day telethon.

When you open up the app and sign up, you'll be prompted to pick some categories you're interested in, so you're shown relevant streams.

When you start watching a lifestream, you can participate with other users in the group chat.

Maharlika is a Filipino restaurant in Manhattan's East Village that sells one of the strangest foods you can buy in New York City. It's called balut, and it's basically a hard-boiled egg with a partially formed duck fetus inside.

We learned how to properly eat a balut from Maharlika owner Nicole Ponseca, and then took some back with us to the Business Insider offices to see how our coworkers would react.

A New York City apartment belonging to a noted couple in tech has sold for $2.1 million, the New York Observer reports. 

The former owners of the East Village home are Jeff Hammerbacher, an early Facebook employee and cofounder of Cloudera, and his wife Halle Tecco, founder of medical venture fund Rock Health.

They bought the apartment from Chloe Sevigny for $1.76 million in 2012. The couple then spent nine months renovating the space.

"We struggled to use color in our last apartment in San Francisco, which was all gray and navy, so we really wanted to experiment with color, pattern, and texture in this home," Tecco told Business Insider when the apartment first listed in June.

The buyer is reportedly Shana Randhava, executive director of the Estee Lauder Companies.

The one-bedroom apartment is located on the garden level of a townhouse in the East Village.

The entryway has some bright green patterned wallpaper.

The living room is filled with lots of texture and color. Its best features include a wall-length bookcase and a fireplace.

At least 120 people were killed and many more were injured in a series of shootings and bombings across multiple locations in Paris Friday evening. 

Residents of countries all over the world were shocked, alarmed, and saddened for the people of France. Online, the hashtag #PrayForParis took over social media, and a Paris peace sign symbol was posted by hundreds of thousands. 

Over the weekend, major cities around the globe paid tribute to the victims by brightly illuminating landmarks with the colors of the French flag.

Between "Trainwreck" and "Inside Amy Schumer," comedian Amy Schumer is having the biggest year of her career.

Now, she's using her clout to give back. 

Schumer co-founded Stylefund with "Trainwreck" costume designer Lisa Evans. Stylefund "helps women create their individual style to step out into the world with confidence," and especially focuses on dressing women, primarily veterans, who are re-entering the workforce.

"It's such a stressful thing for women, and clothes only go up to a size 12. And then they just send you out to a field and are like, 'here's a tarp!' The proportions change and that message... it's just awful," Schumer told Alec Baldwin during an interview on his podcast, "Here's the Thing."

The media's depiction of women also inspired Schumer to launch Stylefund. 

"The images that we see of these women every day all over magazines and TV — and now with this huge celebrity culture — that's not how people look. And you just feel like, 'well, I'm disgusting and I'm not worthy of love,'" Schumer said.

A 300-year-old property owned by the former chairman and president of Morgan Stanley is now on the market for $17.5 million.

Listed by Plantation Services, the South Carolina property was once a home for the late S. Parker Gilbert and his wife, Gail Gilbert, according to The Wall Street Journal.

S. Parker Gilbert died in May at 81.

The couple purchased the home for $2.55 million along with 800 acres, according to the report. The property is now 1,705 acres.

The historic property is the third-oldest plantation in South Carolina, and was built by Thomas Broughton, who went on to become the royal governor of South Carolina in 1735.

Scroll down to see the house and two guest houses, situated 45 minutes outside Charleston.

Welcome to the Mulberry Plantation. The property is vast and surrounded by water, ...

... and full of arching, ancient trees.

Here's the main house, known as the Mulberry House — aka Polly or Salt Point.

It isn't just wealth. And it isn't just control over people or resources. No, true power is a potent combination of money and influence that enables people to help shape the world. But only a select group of people really possess the economic and political clout to effect global change. For better or worse, their decisions affect millions, shake industries, and change nations.

Business Insider has compiled the following list of the world's most powerful people — heads of state, billionaires, CEOs, and entertainers. To determine the ranking, we considered more than 100 of the most influential players in business, politics, and entertainment, and we evaluated their influence by using metrics in four major areas: economic power, command, newsworthiness, and impact— a subjective measure that captures how important they are in their respective spheres.

Because the majority of these people span several industries, we took the logarithm of each and mapped those logarithms to a standardized scale, which allowed us to combine the metrics. (See our full methodology here.)

US President Barack Obama, leader of the world's chief superpower, takes top honors, followed by Chinese President Xi Jinping, ruler of the a country making a serious challenge to US supremacy. Read on to see the full list of the world's 50 most powerful people right now:

50. Jay Z and Beyoncé

Titles: Singer (Beyoncé), rapper and entrepreneur (Jay Z)

Country: US

Age: 34 (Beyoncé), 45 (Jay Z)

Music's biggest power couple, Beyoncé and Jay Z turn nearly everything they touch into gold, which has helped them mint a combined fortune of $950 million.

Beyoncé shocked the music industry in 2013 when she released an album on iTunes without promotion — it went on to sell over 5 million copies thanks to hits like "Drunk in Love" and "Partition."

Jay Z is consistently one of the highest earners in music, reportedly raking in $56 million last year through his many ventures, including his Roc Nation music label and its sports division. Though his streaming service, Tidal, encountered some turbulence— the hip-hop mogul himself forgot he owned it— Jay Z is still just about everywhere in the entertainment industry.

49. Mukesh Ambani

Title: Chairman, managing director of Reliance Industries

Country: India

Age: 58

Mukesh Ambani took over as the chairman of Reliance Industries when his father, the company's founder, Dhirubhai Ambani, died in 2002. The enormous industrial conglomerate generates $61 billion in annual sales from its interests in energy, petrochemicals, textiles, natural resources, retail, and, more recently, telecommunications.

Ambani is the richest person in India with a personal fortune of over $23 billion. He owns a 27-story Mumbai mansion that cost $1 billion to build.

And if Ambani's projections for India's economy prove correct, expect that net worth to soar. Four years ago, Ambani predicted that India would grow from a $1.4 trillion economy in 2011 to a $30 trillion economy by 2030 — a bullish estimate considering that India's GDP today stands at $2.2 trillion.

48. Joaquín 'El Chapo' Guzmán

Title: Sinaloa Cartel leader

Country: Mexico

Age: 60

Mexican drug lord Joaquín "El Chapo" Guzmán is perhaps the wealthiest and most notorious gangster on the planet, with a net worth of $1.1 billion. The leader of the infamous Sinaloa Cartel, El Chapo has been accused of importing over 180,000 kilos of cocaine into the US. Drug-enforcement experts estimate his cartel's annual revenues at greater than $3 billion.

Cunning and evasive, El Chapo escaped from a Mexican prison in July (not for the first time) by way of a labyrinthine tunnel he may have paid $50 million in bribes and construction costs to have built. The US State Department is offering a reward of up to $5 million to anyone with information leading to his arrest.

Watching the Ponsse Beaver tree harvesting machine in action is nothing short of mesmerizing. The machine makes giant trees look like nothing more than toothpicks.

Ponsse is a Finnish company that makes industrial logging machines like this tree harvester.

Forget axes: this video of one of these harvesters in action shows how quickly and effortlessly modern machines can move through the forest.

The Ponsse Beaver latches onto the tree, cuts it at the base, picks it up, and simultaneously cuts it to size and removes the limbs.

Take a look.

2013 marked an all-time high for Istanbul's tourism industry.

The city hosted 838,000 visitors in the first quarter of that year alone, a benchmark that hadn't been hit for a decade.

Tourism numbers for the country have since slipped, causing a drop in hotel prices, which means it's a great time to plan a trip to the city.

If you're in need of some inspiration, we've compiled a set of vintage photographs of the city taken by amateur photographer Charles Cushman during the 1960s.

Cushman's photos are evidence of the city's rich history and culture, both of which are still apparent to visitors of the city today.

Here's Cushman's view of the Marmara coast from the Pan Am flight he took into Istanbul. The Marmara Sea, along with the Bosphorus and Dardanelles Strait, form the boundary that separates the Asian half of Istanbul from the European half.

While in Istanbul, Cushman stayed at the Hilton, which can be seen here, along with the Dolmabahce Mosque.

The Hilton offered spectacular views of the Bosphorus Strait.

Actor Charlie Sheen revealed that he's HIV-positive in an interview with the Today Show.

He then goes on to explain that since his diagnosis four years ago he has been extorted out of millions of dollars by people threatening to leak the information.

He put the amount he has paid in "shakedown" money at "upwards of $10 million," and added that "What people forget is that's money they're taking from my children."

One of the reasons he decided to go public with the information was to end the extortion.

The chicken nugget was created by a food scientist at Cornell University more than 60 years ago.

Since then, the breaded pieces of chicken meat have become a part of nearly every fast-food menu.

McDonald's, Burger King, Wendy's, and Chick-fil-A each have their own approach to the chicken nugget, and we set out to find which chain does it best.

The fast-food greats meet for our chicken-nugget face-off: Burger King, Chick-fil-A, McDonald's, and Wendy's.

First, Burger King's chicken nuggets. These nuggets are firm, but not crispy compared with other options. We paid $5.89 for 10 pieces.

On first bite, we taste a little kick — possibly thanks to the noticeable pepper flakes in the breading. But these nuggets have a spongy texture that feels questionable.

"Master of None," the new Netflix comedy co-created by Aziz Ansari, is one of the most critically-acclaimed new shows on television. One of the show's standouts was the episode "Indians on TV," which is about trying to be an Indian actor without resorting to stereotypes.

Actor Ravi Patel guest-starred in the episode, and argues with fellow actor Dev (Ansari) about whether or not it's okay to do a stereotypical Indian accent while auditioning for roles. Patel thinks it's fine, while Dev refuses.

However, their real-life differences on the issue almost made Patel turn down the role. Despite saying he was flattered, Patel told INSIDER that he initially said no.

"When I read it I thought it was kind of condescending to the blue collar Indian actor," he explained. "He was talking a lot about how he doesn’t do the accent. I felt it was condescending to guys who do do the accent. I'm one of those guys, and I’m also friends with all of those guys, and I just have a lot of sympathy for the inherent kind of s****y role exposure that you have to endure if you're a blue collar actor... just trying to work your way up to get to a place where you can say no..." 

If you've seen the episode, this might sound familiar. Patel and Ansari talked it out in real life, and it was this disagreement that led Patel to being cast.

"He called back and he was like, ‘Hey man, I can see why you think that but that's not at all what I want. In fact, that's why I want you to do this,'" Patel said. "I just thought it was a really mature response."

The entire first season of "Master of None" is now streaming on Netflix, and "Meet the Patels," a documentary that Patel co-directed with his sister, Geeta, is playing in select theaters.
