For most of Volvo's 90-year history, the Swedish automaker offered its loyal legions of customers well-built, safe, and practical transportation with a certain Scandinavian flair. Now, the company's diving head-on into the world of luxury cars.

On the heels of the hugely successful introduction of the XC90 luxury SUV, Volvo introduced a new generation flagship luxury sedan — the S90 — in 2016. The S90 replaced the company's S80 sedan. Although a rather nice car, the S80 was on sale with minimal revision for nearly a decade. Near the end of its run, the car certainly showed its age. And the conservatively styled S80 was never been able to drum up the big sales figures Volvo would have like to see from the model.

With Volvo's S90 sedan firmly entrenched in the market, we take a look back at the company's flagship four-door sedans. Although they may not have always been overly luxurious, Volvo has always offered a big executive ride for those who sought the experience.

Although Volvo's foray into the car business started in the mid 1920s, its first offering with a luxury tilt was the PV 654 in 1933. It featured an upgraded, plush interior, twin spare tires and a reversing light. It was powered by an 80-84 horsepower 3.67-liter, 6-cylinder engine.

In 1935, Volvo followed up with the sleek PV36 "Carioca." In addition to the aerodynamic body, the Carioca featured advanced independent front suspension and room for six.

Volvo built a total of 501 Cariocas, powered by the same 3.6- liter, 6-cylinder found in the PV654. Volvo claimed a top speed of 75 mph.

The time has come to reach for the best and brightest that the beauty industry has to combat those dreaded cases of summer frizz, sweats, and running makeup.

Want glowing, youthful skin like Gwyneth Paltrow's? All you need is a whole lot of money — and a willingness to get stung by bees. 

Paltrow and her lifestyle brand Goop have often been ridiculed for doling out impractical and unproven health advice. (Remember when she said she'd "rather smoke crack" than eat spray cheese?)

Her beauty tips often veer into the same territory. Goop sells and recommends plenty of cosmetics with steep price tags (no surprise considering Paltrow spends a rumored $18,000 a month on her beauty routine). The site is rife with beauty tips based on skimpy — sometimes nonexistent — scientific evidence. And Paltrow herself has used her platform to promote some eyebrow-raising procedures, including the aforementioned bee stings. 

Here's a look at some of the absolute worst beauty tips that Paltrow and her brand have tried to push.

DON'T MISS: What the author of 'Eat Fat, Get Thin' eats — and avoids — every day

BAD TIP #1: Take supplements for beauty.

Goop sells its own line of supplements for $90 a month. The site also quotes experts who recommend all manner of  vitamins, minerals, and herbs. This post alone extols the supposed beautifying effects of of folic acid, vitamin B12, magnesium glycinate, fish oil, ECGC (a green tea extract), n-acetyl cysteine, s-acetyl-glutathione, biotin, zinc, silicon, iron, vitamin B6, leucine, vitamin A, vitamin E, vitamin C, pancreatic enzymes, and lycopene. That's (literally) a lot of pills to swallow.

The major problem with this advice: Many supplements are useless at best and dangerous at worst. They aren't required to undergo any kind of safety or efficacy testing before they hit store shelves. That means you might be shelling out money for something that doesn't change your appearance or your health in any way. Even worse: People get hurt and even die because of supplements — they send about 20,000 Americans to the ER every year. 

But if you really want to try a supplement, talk to your doctor and check out this buyer's guide.

Sources: Goop, Harvard University, New England Journal of Medicine 

BAD TIP #2: Get a threading facial.

Goop describes threading as an "under-the-radar" face lift "that's sending A-listers flocking to Europe and Asia." That's because it's no longer allowed in the United States.

Allure reports that threading facelifts — in which a doctor uses a barbed thread to lift sagging skin — were approved by the FDA back in 2004. But enough women reported adverse side effects that the procedure lost FDA approval. 

Even if you could get it in the states, you might not want to: A 2009 study found the facelifts don't offer lasting results. Also, they cost up to $11,000.

Sources: Goop, Allure, JAMA Facial Plastic Surgery

BAD TIP #3: Soak in a "detox" bath.

As a general rule, most products or diets that claim they'll "detox" you are total bunk. Our livers and kidneys do the work of detoxification whether we use Goop-approved products or not. 

So while it might feel nice to soak in the "Digital Detox" bath sold on the Goop website, there is little reason to believe that it "draws out toxins associated with excessive exposure to technology."

Maybe you're touring the US as a citizen out to see your homeland. Or maybe you're coming from afar to see what America has to offer. Either way, you probably want to make the most of your travels. 

While some tourist spots across the country have become legendary landmarks that everyone should see, others are just disappointing tourist traps. Some are blatant attempts to make money, others are plain weird, but either way, they should be avoided at all costs.

Save your time, money, and sanity by skipping these 50 tourist traps.

The NBA Draft order has been set, and teams are beginning their workouts.

This year's draft class is considered one of the best in years and could have a big impact on the league.

With the draft just over one month away, we surveyed seven experts' mock drafts and found the consensus pick for each team. If there was no consensus, we picked among the seven experts for a good pick.

Our experts: Chad Ford of ESPN, DraftExpress, The Ringer, Scott Howard-Cooper of NBA.com, Jeremy Woo of Sports Illustrated, Gary Parrish of CBS, and NBADraft.net.

1. Boston Celtics — Markelle Fultz, G

Experts: 7 of 7

School: Washington

Other possibilities: none

Key expert quote: From Ford: "If they keep the pick, Fultz is the clear choice for them. He can play both the 1 and the 2, he stretches the floor and he has the build to contribute right now."

2. Los Angeles Lakers — Lonzo Ball, PG

Experts: 7 of 7

School: UCLA

Other possibilities: none

Key expert quote: From Howard-Cooper: "Family issues are a non-factor for front offices because the Ball who will be drafted comes across as grounded, relaxed and, more than anything, a team player. He has great vision and is a pass-first point guard with the basketball IQ to deliver the ball at the right time and the right place."

3. Philadelphia 76ers — Josh Jackson, F

Experts: 4 of 7

School: Kansas

Other possibilities: Malik Monk (G, Kentucky), Jayson Tatum (F, Duke)

Key expert quote: From Parrish: "He projects as a high-level contributor on both the offensive and defensive ends of the court. He'll make the Sixers more athletic, right from the jump."

If you're in your hometown's top 1% of earners, there's no doubt that you're doing well for yourself.

But not all one-percenters are created equal.

The Economic Policy Institute calculated how much money puts a household in the top 1% of income earners in every metropolitan area in the US. For the US overall, the income threshold required to be in the 1% of earners is $389,436 pre-tax, but for populous places like San Francisco and Houston, that number rises to $785,946 and $606,286, respectively.

Below, we've highlighted the annual household income required to be in the top 1% for the 15 largest cities in the US, as determined by the Census Bureau. (But keep in mind that the income thresholds listed apply to the entire metropolitan areas.) We've also included median household income — in 2015 dollars — for comparison purposes.

Goldman Sachs was honored at a gala dinner for Room to Read, a global organization seeking to transform the lives of millions of children in Asia and Africa, at the High Line Hotel on May 11. 

David Solomon, president and co-chief operating officer at Goldman Sachs was an honoree on the night. He told Business Insider he was picking up the award on behalf of CEO Lloyd Blankfein, co-COO Harvey Schwartz, and the more than 120 current and former partners who have contributed to the charity. 

A number of top Goldman Sachs executives making generous contributions on the night. Greg Lemkau, who had just been promoted to cohead of the investment bank, made a donation, as did his cohead John Waldron. FX de Mallmann, chairman of investment banking, and Dan Dees, head of tech, media and telecoms banking, also made big contributions. 

The level of their generosity was only challenged by PIMCO, with a number of executives at the bond giant, including Andrew Balls and Marc Seidner, making large contributions. In all, the event raised $2.8 million.

Sean 'Diddy' Combs was presented with the Superhero Award for his commitment to education. The rapper and entrepreneur is the cofounder of Capital Preparatory Harlem Charter School. At one point, Combs raised the stakes in a bidding war during a charity auction, offering to personally produce a track for the winner. Someone on PIMCO's table weighed in with a $50,000 bid to bag the prize. 

Take a look at the event:

John Wood, the founder of Room to Read, welcomed guests to the gala dinner.

Howard Schiller, the former CFO of drug company Valeant, mingled with the crowd.

Edith Cooper, global head of human capital management at Goldman Sachs, was there.

The FBI has released 27 new photos of the Pentagon on 9/11 after it was struck by a plane that was hijacked by five terrorists. 

Five al-Qaeda terrorists took over American Airlines flight 77, which was traveling from Washington DC to Los Angeles, as it flew over eastern Kentucky. They then turned it back towards Washington, D.C., eventually crashing it into the Pentagon, killing 184 people. 

The pictures released by the FBI show debris from the plane, the Pentagon on fire and crews putting out the blaze and cleaning up the damage.

The economic profession has got a bad rap in Britain recently with the failure of "so-called experts" often cited by pro-Brexit campaigners as a reason to mistrust economists who overestimated the negative impacts of Brexit on the economy. Despite this, interest in economics as an academic subject is on the rise.

This week, the Guardian published its annual ranking of the UK's best universities, which ranks establishments according to a number of factors including course satisfaction, student to staff ratio, and career prospects.

The ranking is broken down into subject areas, with economics one of those covered. Business Insider decided to take a look at the top universities for studying the subject in the UK.

As the ranking heavily favours student satisfaction as a criteria, rather than pure academic achievement, some powerhouses like University College London, Manchester University and even the London School of Economics miss out.

Check out the schools the Guardian ranks highest, below:

13. Loughborough University — 78.3 points: Generally better known for its sporting prowess than its academics, Loughborough is actually hugely impressive when it comes to teaching and research. The university finished joint 6th overall in the Guardian's ranking.

12. St Andrews University — 78.8: Located in a quiet seaside town famous as the home of golf, St Andrews is something of an academic hotbed. Notable alumni include Britain's Defence Secretary, Michael Fallon.

11. King's College London — 80.1: With a famous history, King's has educated some 12 Nobel laureates. It scored 92.3 points when it comes to the satisfaction of economics students with their teaching.

Netflix has made a gargantuan amount of original shows and movies in the last few years — and will release 1,000 hours of new content just this year.

You'd have to spend 41 days binge-watching Netflix non-stop to see it all. So if you're like us, you're having trouble keeping track of which Netflix shows are worth your time.

To create a cheat sheet for you, we asked reviews aggregator Rotten Tomatoes to tell us which Netflix shows had the highest critic ratings of all time. We looked only at shows Netflix made itself, not ones it co-produced, or licensed only in some markets. The shows also had to have at least one "Certified Fresh" season, to make sure they have a high enough number of reviews.

Here are the top 24 Netflix original shows, sorted by their Rotten Tomatoes critic score from lowest to highest (if there was a tie, we used the audience score to break it):

Apple is currently rebranding its stores as a place that doesn't just sell iPhones or fix Macs. Apple wants its retail stores to be a place where people feel comfortable gathering. 

A big part of this push is a new program called "Today at Apple," which schedules free classes, concerts, and other programming that people can sign up for online with their Apple ID.

"I’ll know we’ve done a really, really great job if the next generation, if Gen Z says, 'Meet me at Apple. Did you see what’s going on at Apple today?'" Angela Ahrendts told CBS last month when Apple launched the program. 

Apple stores have had classes and other programming for a while, but the new push expands these sessions to all Apple retail locations. 

Some of the classes focus on video editing, or music production, or accessibility features, but the one that caught my eye was a "Photo Walk" in which an Apple employee with the title of "Creative" guides people through a scenic walk and provides tips and tricks for getting the best photos out of an iPhone. Every Apple store will hold a photo walk this weekend. 

I was curious, so I signed up for one. Here's what happened:

"Twin Peaks" is finally back on Sunday night.

Showtime has kept many details of its revival of the cult show close to the vest. But as the premiere inches closer, we'll let you in on the insider details you need to know.

More than 25 years ago, in 1990, "Twin Peaks," a mysterious story set in a quaint Northwestern town rocked by a shocking murder, changed TV forever. Created by David Lynch and Mark Frost, the series only ran for two seasons but went on to become a highly influential cult hit, and now it's finally getting its season three.

If you're dying to know more about Showtime's "Twin Peaks" revival, here's what we know:

David Lynch is directing all 18 episodes.

It's been more than two decades since David Lynch directed episodic television. When asked what fans should expect from his directing style for the "Twin Peaks" revival during the Winter 2017 Television Critics Association press tour, he was fairly vague.

"First, it was just the same as all the others," Lynch said. "I see it as a film, and film in parts is what people would experience. And it was a joyful, fantastic trip with this great crew and great cast. This word 'expect' is a magical word, and people expect things, and their expectations are met, hopefully, when they see the thing."

Despite long days during the shooting of the series, star Kyle MacLachlan expressed his awe of Lynch's work ethic.

"It didn't matter how long [the shoot day was], he was there. He was always up, cheerful, and smiling, and so were we," MacLachlan, who's playing FBI Agent Dale Cooper again, said.

The original script for the revival was 400 pages.

Lynch had his work cut out for him.

“I think it took me six hours and a few cups of coffee to read, but it was wonderful,” MacLachlan told Entertainment Weekly of the first time he read the script.

The production returned to shoot in Washington, the fictional setting and actual shooting location of the original "Twin Peaks."

"[It was] both the same and different," Lynch said at TCA of returning to Washington. "If you go back 25 years in any town and revisit it again, it's that way. It's many things remain the same. But also, you feel a change."

The US stock market may be fresh off its most boring stretch in more than five decades, but there are still stocks that give investors nightmares.

In a client note Wednesday, the derivatives team at Goldman Sachs identified 15 companies that traders see as having elevated downside risk over the next 12 months.

To single out the most feared stocks in its coverage universe, Goldman looked at two measures:

• Twelve-month implied volatility — the estimated price swing for a stock over the next year. Calculated using the price of options.
• Twelve-month skew — the degree to which investors are hedging against losses in a stock, relative to bets on gains. Calculated using the implied volatility spread between one-year put and call contracts.

To qualify for Goldman's "most feared" list, a stock had to have been in the 40th percentile or above for each of these measures over the past year. The firm then ranked those 15 companies in order of 12-month normalized skew percentile.

The following charts show just how much more worry has been baked into these 15 companies over the past year, based on the two measures listed above:

In 2016, Texas became the 45th state to allow the open carry of handguns. But many gun-toting women prefer to keep their weapons concealed for reasons including safety and comfort.

More than 268,000 women hold active handgun licenses in the Lone Star State, up 35% from 2014. Their rising numbers have led to a booming shadow industry: firearm accessories, including bra holsters, concealment leggings, and leopard print gun holders for cars.

In an effort to document women's roles in modern gun culture, photographer Shelley Calton took portraits of her Texas friends for her book, "Concealed, She's Got a Gun." She kindly shared a few photos with us.

Some Texas women see carrying a concealed handgun as more than a right — but a matter of life or death.

As of January 1, 2016, state law permits them to carry a handgun openly or concealed so long as they get a license from the Texas Department of Public Safety.

More women are packing heat than ever. The number of women issued a license to carry rose from 22,000 in 2010 to 103,000 in 2016, according to the Department of Public Safety.

Summer is around the corner, and with it comes the temptation to cool down with an ice-cold beverage from one of your favorite fast-food chains.

But beware; those neon-colored, frivolous drinks are less innocent than you think. Some are packed with more than three times the amount of sugar that the Food and Drug Administration recommends daily. 

According to the FDA, Americans should eat and drink no more than 50 grams of sugar a day — roughly the same amount that's in a single can of Coke.

But the reality is we consume far more. According to the US Department of Agriculture, the average American consumes more like 94 grams a day.

Avoiding sugar can be harder than you think. To help you understand how much sugar your favorite drinks contain, we put together the following series of visualizations in which 1 sugar cube represents 2.3 grams of sugar. 

We chose the largest sizes available at each chain.

Starbucks Sweetened Iced Coffee (venti, 24-oz)

Total grams of sugar: 30

Percent of FDA recommended daily intake: 60%

McDonald's Sweet Tea (32-oz)

Total grams of sugar: 38

Percent of FDA recommended daily intake: 76%

Shake Shack Shack-made Lemonade (24-oz)

Total grams of sugar: 59

Forget about the Ford GT or the Lamborghini Aventador. When it comes to supercars and rivalries, it's all about McLaren versus Ferrari. On Formula One's racetracks, the two have been duking it out for half a century. In fact, Ferrari and McLaren are, by far, the two winningest teams in the history of the sport. 

In 2010, Woking, England-based McLaren Technology Group launched McLaren Automotive — the division of the company focused solely on building road-going supercars. This added a whole new dimension to the rivalry. 

In the years since both companies have unleashed supercar after supercar. Each time besting the latest efforts of its rival. 

The latest salvo in the battle for supercar supremacy is the McLaren 720S. Recently, Business Insider attended the launch of McLaren's futuristic supercar at the demanding Autodromo Vallelunga near Rome. 

As part of the festivities, I got the chance to take the 720S on a two-hour-long drive from our hotel in Rome to the racetrack north of the Italian capital. 

Here's how it went.

DON'T MISS: Which body part hurts the most when stung by a bee? A scientist put himself through a torturous experiment to find out

1. How often should I wash my hair?

The short answer? Nobody needs to wash their hair everyday. Beyond that, it depends on your skin type: if you have normal or dry skin, once or twice a week should do the trick.

2. How often should I brush my teeth?

The American Dental Association recommends you brush twice a day for two minutes, although they don’t specify what time of day the brushing should happen. So long as you do a good brushing before bed, you should be set. While you sleep, your mouth salivates less, which can lead to cavities.

3. When's the best time to put on antiperspirant or deodorant?

The ideal time is right before you go to sleep. That way, if you’re using an antiperspirant, it has time to close your armpit’s sweat ducts before they have a chance to get sweating in the morning. Most last at least 24 hours, so no worries about not making it to the end of the workday.
