There's only one person in all of Africa who makes the list of the 50 richest people on earth: Nigerian businessman Aliko Dangote. When our ranking was released, Dangote's net worth stood at $14.3 billion, equal to 2.5% of Nigeria's GDP. 

The majority of his wealth stems from a more than 90% stake in Dangote Cement, his $2.4 billion in sales company that's publicly traded on the Nigerian Stock Exchange.

Dangote's business interests span several African countries. He owns cement plants in Zambia, Senegal, Tanzania, and South Africa. In 2011, the commodities baron invested $4 billion to build a facility on the Ivory Coast.

Dangote, who has been CEO and president of Dangote Group for 35 years, is also an active philanthropist. As chairman of The Dangote Foundation, he oversees several education, agriculture, and health initiatives, including a $12,000-per-day food program for the undernourished. 

"Aliko is Africa’s richest man, and his business activities drive economic growth across the continent. That’s impressive, but I know him best as a leader constantly in search of ways to bridge the gap between private business and public health," wrote Bill Gates, the richest person in the world, of his fellow philanthropist in Time Magazine. The tech mogul also praised Dangote's success in removing Nigeria from the global list of endemic countries in his fight to eradicate polio.

In January, Dangote and Gates announced a $100 million pledge to cut malnutrition in Nigeria, Africa's most populous country and leading economy. The pair also signed a deal to enhance immunization programs in the country's Northern states.

Dangote tied for 49th on our ranking of the world's 50 richest people— produced with Wealth-X, a company that conducts research on the superwealthy — and is the only black person to make the list.

NOW WATCH: Here’s where the 20 richest people in America live

While frying can reduce the nutritional value of most foods, there's an exception to the rule:

It's a group of foods that contain significant amounts of the organic pigments called carotenoids, which studies indicate can help reduce the risk of several chronic diseases in humans, like heart disease, eye disease, and certain cancers.

When you expose carotenoids to high temperatures, energy from the heat breaks them down. This makes it easier for the body to absorb into your blood stream, where it goes to work against disease.

And if you fry those foods in oil, as opposed to steaming or baking them, you absorb even more because carotenoids are fat soluble.

Where to find carotenoids

Carotenoids are prevalent throughout nature, but the three that are most common in our foods are: 

• Pro-vitamin A carotenoids like alpha carotene and beta carotene, which gives carrots and sweet potatoes that iconic orange color and has been shown to reduce the risk of age-related macular degeneration— a leading cause of vision loss in people over 50.
• Lycopene, which provides most red-hued fruits, like tomatoes, pink grapefruit, and red peppers, their color. About 80% of the lycopene we ingest comes from tomato-based products, and over the last decade, studies have found that the lycopene in tomatoes could be linked to a reduced rate of prostate, lung, and stomach cancers.
• Lutein, which is found in dark leafy greens like kale and Brussels sprouts and has also been shown to reduce the risk of eye diseases, like age-related macular degeneration.

A major nutritional boost

So just how much more of these disease-fighting carotenoids do you get by pan frying them in oil (not to be mistaken for deep frying, which is an entirely different method of cooking)?

We asked Guy Crosby, who has spent 30 years in the commercial food industry business and is now the editor for America’s Test Kitchen and teaches a food science course at the Harvard School of Public Health. You can learn more about him on his site "The Cooking Science Guy."

As Crosby explains: 

"In the fresh tomato most of these [carotenoid] pigments are all tied up with proteins," Crosby told Business Insider. "If you cook the tomato you break down the bonds between the proteins and the pigments — the lycopene — and you absorb about four times more lycopene into your blood from cooked tomatoes than from fresh tomatoes."

But wait, there's more: Carotenoids fall under a class of vitamins called fat soluble vitamins, as opposed to water soluble vitamins like Vitamin C and some types of Vitamin B. This means that carotenoids will dissolve in fats, for example the fat in frying oil, just like the Vitamin B-6 in broccoli dissolves in water when you boil it.

"Since lycopene is soluble in oil, if you cook your tomatoe in olive oil, you'll absorb two times more again above and beyond from what you absorb from cooking tomatoes without the oil," Crosby said.

Now, if you're watching your waist line, it's important to limit the amount of fat you ingest daily. And frying anything is certainly going to up the fat content.

However, you don't need very much oil to get this boost in nutrition — about three to five grams of fat is enough, which is equivalent to one teaspoon of olive oil.

Here's a list from the Micronutrient Information Center at Oregon State University of foods high in the four carotenoids we discussed earlier: alpha-carotine, beta-carotine, lycopene, and lutein.

NOW WATCH: Why you should stop using most antibacterial soaps

If Carolina Panthers quarterback Cam Newton is emblematic of the NFL's style renaissance, then this picture shows exactly why.

When Newton landed in San Jose, California, Sunday, all eyes were on him — well, his pants to be more exact. As he got off the plane, he showcased his most adventurous look yet: gold and zebra-striped $850 Versace pants.

Now, this isn't something we would normally ever recommend someone wear — especially a likely-MVP whose sartorial choices will make national headlines.

That doesn't matter. None of that matters. It all comes down to one thing: confidence. And Newton clearly has it in spades, as he matches the loud-as-heck pants to gold and black leather shoes and an incredibly trendy black leather motorcycle jacket.

These types of loud and garish pants are known in sartorial circles as "go-to-hell pants" and are preppy New England style staples. They're usually bright red (or Nantucket red) or made out of seersucker or patched madras. They're a traditional summer piece for many of the more adventurous East Coasters.

These aren't so much a pair of pants as a lifestyle choice. They say (well, yell, really) to the world: "I honestly don't care what you think about my choices, and I'm going to wear whatever the hell I want". That's an incredibly respectable point of view.

The pants will elicit comments from both friends and passersby, who will in equal numbers approve and disapprove. If you can't handle that, it's best to stay far away.

But if you can rock 'em like Newton — and have thighs that match — then by all means go all-in like he did. But like most things, there are gradients and degrees to it, and Brooks Brothers' take on the classic style is decidedly less bright. That's really saying something when one of the options is a coral pant printed with navy sailboats.

Go for the pair that feels right, but if you're feeling hesitant at all, stay far away. These pants are not for the faint of heart or the man with any kind of hang-ups.

The reserved need not apply.

NOW WATCH: This is how pilots train to fly America's most expensive fighter jets

Of the 50 wealthiest people in the world, only one hails from South America: Brazilian business magnate Jorge Paulo Lemann, who's worth $25 billion.

Brazil's wealthiest man ranks as the 26th richest person in the world, according to data provided to Business Insider by Wealth-X, a company that conducts research on the super-wealthy, as featured in our recent list of the 50 richest people on earth.

Lemann took an unorthodox path to affluence. He worked as a journalist and professional tennis player — he played at Wimbledon — before buying a small brokerage in Brazil for $800,000 in 1971. Lemann and his partners modeled the firm after Goldman Sachs, eventually building it into a powerhouse and selling to Credit Suisse in 1998 for $657 million.

In 2004, he cofounded investment firm 3G Capital, where he’s built a reputation for orchestrating huge mergers and acquisitions, often alongside friend and fellow billionaire Warren Buffett. At the end of 2014, Lemann created a fast-food giant, with the help of Buffett's Berkshire Hathaway, by merging Burger King with Canadian brand Tim Hortons in a series of deals worth over $11 billion.

Then last March, 3G and Berkshire Hathaway teamed up again to invest $10 billion into the megamerger of Kraft and Heinz, which created the fifth-largest food and beverage company in the world with combined revenues of $28 billion.

And in November, 3G's Anheuser-Busch InBev orchestrated a mammoth $108 billion deal to take over SABMiller, becoming the most dominant beer producer in the world. The megamerger puts brand-name beers like Budweiser, Stella Artois, and Leffe all under one roof, and it puts Lemann one step closer to his lifelong dream of controlling the beer market.

Lemann, who also has a home in Zurich, Switzerland, remains notoriously private when it come to his personal life, choosing to let his business performance do the talking.

The traditional "5-pocket" jeans are a staple of every guy's wardrobe, and have been for decades.

With such longevity, it makes sense that some of the garment's original intent would be lost to history.

Some of that intent has been reclaimed on a (quite long) Quora thread asking essentially the same question: What is that tiny pocket-in-a-pocket for?

Well, it turns out, it was originally a watch pocket, meant to be just big enough to slip in a pocket watch, according to the Levi's blog.

A watch in this pocket would be protected from the elements and from scratching, while still being easily accessible to check the time.

Since then, watches have moved to the wrist or disappeared completely. Jeans still have the fifth pocket, though, so we may as well make use for it.

Here are some common modern uses for the vestigial small pocket:

• Coin pocket.
• Ticket pocket.
• Condom pocket.
• Lip balm pocket.
• USB dongle pocket.
• Gum pocket.
• Lighter pocket.

NOW WATCH: Here’s how Shark Tank’s Daymond John beats out the other Sharks to score a deal

There's a new virus called Zika spreading in South America, and on Monday it was declared a "public health emergency of international concern" by the World Health Organization, officially establishing it as a serious threat.

Zika, which has no cure, has been documented in the United States, but only among travelers. And it may be linked with two more serious complications:

• A dangerous birth defect known as microcephaly
• A rare but often temporary disorder where the immune system attacks its own nerve cells

Here's a rundown of the good and bad news about the virus.

First, the good news: Zika is rarely fatal (no deaths have yet been documented in people with Zika virus and no other illnesses). Symptoms of the virus are similar to those of a cold or fever.

And the bad news: It may be linked with a dangerous birth defect known as microcephaly, where babies are born with abnormally small heads. The CDC is also working to determine if there may be a link between Zika and Guillain-Barré syndrome (GBS), a rare disorder where your immune system attacks itself, damaging the nerve cells and leading to muscle weakness and occassionally paralysis. In general, symptoms of GBS last anywhere from several weeks to a few months. Most people fully recover, but others may have permanent damage. In rare cases, it can be fatal.

But that's not the worst news with Zika: There's also no rapid diagnostic test to detect the virus in a newly-infected person, and only about 1 in 5 infected people ever shows symptoms.

Last week, World Health Organization officials said the virus was “spreading explosively” in the region and President Obama voiced his concerns for the Zika virus here in the US, calling for more research into ways to stop the spread of the disease.

This is not the first time the alarm bells have been sounded. Earlier in January, Peter Hotez, Dean of the National School of Tropical Medicine at Baylor College of Medicine, told NBC News that he was "very worried about Zika."

Hotez, who's also the Director of the Texas Children's Hospital Center for Vaccine Development, said that while a single tourist is unlikely to be the cause of an outbreak here, some American cities could be vulnerable to Zika's spread.

"We have to act now," Hotez said.

The problem with Zika: Low-level symptoms and potentially serious consequences 

Hotez added that one of the biggest issues with the Zika virus, which is spread by a certain species of mosquito called Aedes aegypti, is that it "tends to produce low-level symptoms." They include fever, rash, join pain, and red eyes. But there's a bigger problem, too: Once infected, only about 20% of people with Zika ever show those symptoms, according to the CDC. Plus, the illness is typically mild — symptoms usually last anywhere from several days to a week, and hospitalization is rarely necessary.

But the virus, while not necessarily damning in and of itself, has been linked with a far more concerning problem: babies born with abnormally small heads, a serious condition known as microcephaly. After some mothers showed symptoms of the virus during their pregnancy, their babies were born with the condition. 

Since the outbreak of the Zika virus in April 2015, Brazil has documented 4,180 cases of the condition in babies born to women who were infected during their pregnancy — 20 times the rate of the previous year and a 7% increase from the number recorded just last week.

Still, scientists can't say for sure what the link is between Zika virus and birth defects.

"We know very little about how Zika virus infection occurs during pregnancy and how it causes birth defects," Dr. Yoel Sadovsky, Director, of the Magee-Womens Research Institute and a professor of obstetrics, gynecology, and reproductive sciences at the University of Pittsburgh told the Genetic Expert News Service.

Based on research on how other viral infections behave during pregnancy, Sadovsky added that "several steps" are likely needed for a virus to affect the fetus and most likely include crossing the placenta, the organ that connects a developing fetus to a mother's uterine wall and allows the fetus to take in nutrients.

Where the virus is now

So far, the disease has been identified in a number of states in people who recently traveled to areas where the virus is being transmitted locally. Local transmission of the virus, which is spread by mosquitoes, has been documented in Puerto Rico and the US Virgin Islands as well. 

Here are the 28 countries and territories where the virus had been transmitted locally as of Monday, February 1:

In the US, no local transmission of the virus has been documented yet — so far it has only been diagnosed in people who've recently traveled to places where it is being transmitted locally.

What you need to know about Zika in the US

While there has not been any local transmission via mosquitoes in the US yet, the WHO has previously warned of this possibility. Zika is spread by Aedes aegypti mosquitoes, which are prevalent in many American countries and thrive in tropical climates. This is why experts like Hotez have warned of it popping up in areas in the US with wet lowlands, warm temperatures, and species of mosquito that can transmit the virus.

"I am quite worried about Zika taking off on the Gulf coast," Hotez told NBC News.

The first reported case of a traveler with Zika in the US was in Texas. Since then, travelers have tested positive for the Zika virus in New York, Los Angeles, and in other countries outside the Americas.

When it comes to mega-mansions, this 33-bedroom Florida compound on a private barrier island is pretty hard to beat. Sitting just south of Palm Beach in Manalapan, it's listed for $195 million, making it the second-most expensive home for sale in the United States right now.

(First place goes to the infamous Playboy Mansion, which is on the market for $200 million as of last month.)

The 16-acre estate, named Gemini, is the property of the billionaire family of deceased publisher William B. Ziff, Jr. Ziff passed away in 2006. He had developed a hugely successful empire of tech-focused magazines, including titles like Car and Driver and PC Magazine. The family sold the publishing arm of Ziff-Davis for $1.4 billion in 1994, the New York Times reported.

The massive, lush property is decked out with all of the perks that you'd expect for the astronomical price tag. It's bordered on both sides by private beaches and its own pier. On top of that, there's a golf course, pool, tennis court, and basketball court. 

Gemini is listed with Carmen D’Angelo, Jr., Joseph Liguori, and Gerard Liguori of Premier Estate Properties.

Gemini spans the width of a barrier island in Manalapan, just south of Palm Beach. That means it has private waterfront access on both the ocean and river sides — not to mention plenty of green space.

The property includes a 12-bedroom main home, as well as a seven-bedroom guest house, two "ocean cottages", a manager's house and office, and a tree house. It makes for a grand total of 84,988 square feet of interior space.

A PGA-standard golf practice area means you never have to leave the private island to work on your drive. You'll also find a freshwater pond, bird sanctuary, and "sports complex" with tennis, basketball, mini golf, and playground setups. To top it off, there's a butterfly garden complete with model train, and a fully-furnished underground tunnel connecting different parts of the compound.

The Oregon Trail has held a special place in the hearts of many since it debuted its iconic mix of history, addictive gameplay, and dysentery in the 1970s.

But even though the game was beloved by teachers for getting kids excited about history, there was one perspective the game was missing, according to co-creator Don Rawitsch.

In a Reddit AMA, Rawitsch said it would had been interesting for them to add a Native American viewpoint, “perhaps a character who watches the wagons come into that territory.” He also said that in the game, the creators were careful to label raids “riders attack,” since they often came from “white bandits,” and not Native Americans.

Rawitsch also shared that he hopes the words on his tombstone would be, “He helped kids learn,” and that he can’t wait for a virtual reality version of the game. Neither can we.

The Centers for Disease Control (CDC) has urged pregnant women not to travel to countries that have reported cases of the Zika virus, an untreatable, mosquito-borne disease.

The Zika virus has recently been linked to a neurological disorder that causes babies to be born with small craniums and limited brain development, a condition called microcephaly.

In 2014, there were 146 cases of microcephaly in Brazil. In 2015, the rate of babies born with microcephaly grew to be 20 times the normal rate.

Since the outbreak of the Zika virus in April 2015, there have been close to 4,000 cases in newborn babies from women who were infected during their pregnancy. 

The Zika virus is transmitted through the Aedes aegypti mosquito, and the symptoms — which include a low-grade fever, small rashes, joint pains, and red eye — are relatively mild, which is why it did not cause much alarm when the outbreak started in Brazil early last year. 

Below are shocking images of the birth defect caused by the Zika virus.

NOW WATCH: These are the foods a food-poisoning attorney refuses to eat

What's something you've always wanted to accomplish but never have?

Maybe it's launching your own company, or maybe it's finally getting in shape.

Whatever it is, it probably seems like there are insurmountable obstacles standing between you and your goal, from your demanding family to your busy work schedule and your deep-seated fear of failure.

But the truth is, these goals are completely achievable — and in most cases, you are the only one holding yourself back.

That's according to Bernard Roth, a professor of engineering and the academic director of the Hasso Plattner Institute of Design (the d.school) at Stanford University. Roth's new book, "The Achievement Habit," outlines how a strategy called "design thinking" can help you create meaningful changes in your life.

Design thinking was invented by Roth and other Stanford engineers, and it's typically used to improve on a specific product or experience, like a lightbulb or online dating. Yet in "The Achievement Habit," Roth explains how the very same process can be turned inward, helping individuals become happier and more successful.

The book is based on a class Roth has been teaching for nearly half a century, called "The Designer in Society."

Design thinking is a five-step process:

1. Empathize: Learn what the issues are.

2. Define the problem: Which question are you going to answer?

3. Ideate: Generate possible solutions.

4. Prototype: Abandon perfection and either build your project or develop a plan.

5. Test and get feedback from others.

Roth says the individual steps aren't as important as some of the guiding principles behind design thinking: a bias toward action and limited fear of failure. The point of design thinking, according to Roth, is to challenge your automatic thinking and assumptions.

So how does design thinking work in real life?

Over at The New York Times, Tara Parker-Pope explains how the strategy helped her lose weight, something she'd long struggled with.

For the first step (empathize), Roth suggests learning what the real issues are by asking, "What would it do for me if I solved this problem?"

Parker-Pope realized she would feel better about herself, have more energy, and have more confidence to socialize with friends. So the real problem was not so much weight loss, but focusing on her friendships and boosting her energy.

In the process, she realized that carb-loading around lunchtime and eating sugar were making her tired during the day, so she eliminated both. "In shifting my focus away from weight loss to the real issues weighing on my life," Parker-Pope writes, "I ended up losing 25 pounds."

In the book, Roth also describes how design thinking helped a mom in one of his workshops stop worrying about her daughter getting into a good college.

The mom thought the key question was, "How do I make sure my daughter gets into a good college?", but Roth helped her realize that the real question (step two: define the problem) was, "How do I become less anxious?" That's because, once the daughter was admitted somewhere, she'd probably start worrying about something else.

With this new realization, the mom could start working on the big-picture issue of reducing her anxiety.

Design thinking can be equally helpful for working toward professional goals.

Roth gives an example of a student in his "Designer in Society" class named Paddy, who had always wanted to start his own business. Paddy was a journalist who had served in the marines, but when Roth encouraged students to dig deep and be honest with themselves, Paddy realized that none of his accomplishments had made him happy.

"He was just doing a good job walking the paths others had created," Roth writes.

Each student in the class has to complete a term project, which involves doing something they have wanted to do but have never done — and Paddy chose to produce his own radio show.

"In my class [Paddy] learned not to recoil or procrastinate when a new idea arose, but to act," Roth writes. So Paddy prototyped and produced several new products for the radio program "Marketplace." Later on, he published a book about economics.

Design thinking helped Paddy mostly by making doing an imperative, instead of thinking about doing (that's why step four is about prototyping).

The most valuable part of design thinking, Roth says, is that once you realize you can achieve one goal, you gain momentum toward achieving the next one. In other words, it becomes an "achievement habit."

Roth writes: "The experience of taking control of your life will change your reality, making it possible to achieve almost anything you seriously want to do."
