Hawaii's Kilauea Volcano has experts paying attention and asking those in proximity to the eruption to be prepared. On Tuesday, the US Geological Survey (USGS) raised its alert level to "red," indicating that "Major volcanic eruption is imminent, underway, or suspected with hazardous activity both on the ground and in the air."

Still, at Volcano Golf and Country Club, some ambitious golfers found the time to sneak in a few holes as ash flung into the air behind them, leading to some stunningly asynchronous images captured by Mario Tama for Getty Images. You can take a look at the wild scene below.

Despite the red alert now in effect, a few focused golfers were able to find the time to get a few holes.

Volcano Golf and Country Club is aptly named, but is reportedly safe from the path of the volcano for now. Sanae Gathwright, vice president of golf course operations, said that they're ready to move if that changes. "If something happens, we'll be out of here in minutes," Gathwright said.

Some playing the course posted photos of the scene to Instagram — it's tough to imagine a more difficult distraction than a natural disaster playing out in the background.

• Hong Kong has one of the worst housing crises in the world, and has been ranked the least affordable city for housing for the last eight years.
• Hong Kong architect James Law has designed a low-cost solution to the problem: stackable, retro-fitted water pipe "tube homes" called "O-Pods" that could be rented cheaply to young people.
• Law sees the design as an "open-source" solution for housing crises around the world.
• The first O-Pod development is being built in Shenzhen, China and due to open in July.

Hong Kong has one of the worst housing crises in the world, with property prices so high that a single parking spot sold for $664,000 last year and all but the wealthiest are stuck renting tiny apartments with an ever-proliferating range of colorful names: micro-flats, nano apartments, coffin apartments, and cage homes.

It's gotten so bad that the city has been ranked the least affordable city for housing in the world for eight years running, according to the Annual Demographia International Housing Affordability Survey.

"We are facing a tangible affordability problem in our cities," architect James Law told Business Insider. "It is almost beyond the reach of most people to afford to live in a proper home in Hong Kong

Law thinks he may have a solution: a retro-fitted concrete water pipe. 

The idea came to him last August when he was overseeing a construction site. He noticed some leftover concrete pipes at the site and found that they were large, strong, safe, and not being used. Law designed and built the prototype for the O-Pod in less than a month.

The O-Pod wasn't Law's first "crazy project"— he tries to challenge himself with one each year — but it is the first to garner attention across the world. Within months, the O-Pod had been written up in the New Y0rk Times, the South China Morning Post, BBC News, and Business Insider. And he has received inquiries about the design from firms in New Zealand, South Africa and Hawaii.

In April, Law signed a contract with a developer in Shenzhen, China to build the first O-Pod complex.

"​The big dream of mine is not necessarily me doing it, but a global community of people who share the same values using this as an open source design to share around the world," Law said. 

"If we can work with governments, and even private landowners and manufacturers, we could very cheaply build the O-Pods, and we could rent them out very cheaply to young people who are struggling to afford housing."

Law recently gave us a tour of the prototype and revealed where he wants to take it from here. Here's what it was like:

The prototype of the O-Pod is located beneath a bridge in Kwun Tong, a former manufacturing area in East Kowloon.

The O-Pod is made from two sections of concrete drain pipe and has a living space of around 100 square feet. Law's goal for the O-Pod was to create something that was cheap, easily maintained, and quickly built.

Key to keeping the costs down is using a pre-manufactured product, according to Law.

"When you build it yourself, it's expensive and requires labor, quality control, and testing," Law said.

But because the O-Pod uses concrete water pipes, which are already being mass-manufactured, they are "low-cost, well-engineered,  and being concrete, these pipes have good insulation properties."

Designed to go underground, they are also extremely strong and can be stacked on top of each other to immediately become a building, without having to build additional ‘bookcase’ structures, columns and beams, etc [as is the case with shipping containers].”

The O-Pod feels bright and spacious when you step inside. Though the floor space is 100 square feet, the curved walls and the tilted lights make it feel much bigger.

In the past week, networks canceled dozens of TV shows.

And some cancellations were quite shocking, like Fox's decision to cut "Brooklyn Nine-Nine," a comedy that has such a devoted cult following that NBC saved it 31 hours later. 

But not all canceled shows have been so lucky — so far.

But there's still hope. Netflix has saved shows in the past, like AMC's "The Killing" and "Longmire." And Hulu is also no stranger to saving a Fox comedy: It brought "The Mindy Project" back for three additional seasons. 

Here, we selected a few shows that were just canceled by networks that Netflix could — or more accurately, should — bring back, and why.

"Designated Survivor"— canceled by ABC

"Designated Survivor" is much messier than you'd expect a straight-forward and short-lived political thriller to be. In its two-season run, the show had four different showrunners, and lost its female lead when Natascha McElhone left for a Hulu show. But it is kind of a good time, which might be why Netflix is reportedly looking at saving it with a third season (and a fifth showrunner). 

"The Mick"— canceled by Fox

"The Mick" is wild. Every episode takes things further than you can imagine for network TV, and it had the best physical comedy on TV, and one of the best child actors. If Netflix can't save "The Mick," it should at least give Jack Stanton, who played the youngest Pemberton, his own show. 

"The Expanse"— canceled by SyFy

Netflix has shown interest in sci-fi this with shows including "Altered Carbon" and "Lost in Space," and with movies like "Mute.""The Expanse" is one of the best sci-fi shows since "Battlestar Galactica," and it, at the very least, deserves to wrap things up with a short fourth and final season (or a movie). People are already campaigning for a streaming service like Netflix to save the show, and we hope they're listening. 

• Figuring out how to dress for work can be confusing and frustrating.

• But dressing appropriately for the job is crucial.

• From casual clothing to boardroom attire, here's a handy guide to dressing for success.

There was once a time when every professional, no matter his or her industry, put on a suit each morning.

But today, there are so many interpretations of formal and business casual that it can be easy to look sloppy or over-dressed if you're not aware of the environment.

Sylvie di Giusto, founder of Executive Image Consulting, works with executives looking to improve how they present themselves and professionals hoping to impress their clients and bosses. In her book "The Image of Leadership," she breaks down the five levels of dress code that she uses with her clients.

If you're not sure which level is most appropriate for your work environment, the basic rule of thumb is "the more you deal with a client's money, the more traditional and conservative you should be dressed," di Giusto told Business Insider.

In general, that means that people in finance, law, and accounting, for example, should stick to traditional business attire, and those in creative industries, like entertainment and advertising, can dress more flexibly within the casual levels.

If you're a member of the board or meeting with a member of the board, boardroom attire is most appropriate — regardless of the size of the company.

That being said, di Giusto added that there is "no cookie cutter approach'" or a "one-size-fits-all formula."

"In fact, professionals must be able to adapt and adjust their professional style based on the industry they work for — plus the clients they serve," di Giusto said.

For example, she noted that boardroom attire "might look very different in a startup in Silicon Valley than for financial advisors or attorneys in New York City."

Ultimately, di Giusto said, it's up to you to choose what works best in your office environment.

"Everything goes, from pants, dresses, skirts, jumpsuits — as long as they represent themselves in the best possible way and choose the right fit, fabrics, colors, and patterns," she said.

When it comes to dressing for success, you've got a ton of options. Below are some ideas of what you could wear for each level of dress based on di Giusto's recommendations:

• Although we like to think all friendships are healthy, there are some that can be toxic to you.
• If your friendships are draining, one-sided, and have you hide who you truly are, these are all examples of toxic relationships.
• Searching for and holding on to friendships that put out the same energy that you give is one way to form healthy relationships in your life.

We've all been there. Having that one friend (or two) who we keep around knowing that we shouldn't. Sometimes we do it out of obligation to the number of years our friendship has lasted and other times, we just don't want to believe that they're not good for us. Though the characters on "Gossip Girl" might have convinced you that double-crossing your friends is fine just as long as you work it out in the end, real friendships shouldn't continuously bring toxic energy into your life.

Since we can't always notice when things aren't right in our relationships, here are six signs that you should keep in mind that can help you determine if your friendship is toxic.

Your friendship is one-sided.

Whether you've been friends for 10 years or just for 10 weeks, you should always feel like your friendship goes both ways. According to Tonya Seavers Evans, executive image and style consultant, you should look for the same qualities in a friend that you look for in a business collaboration so that it becomes a "win-win" for all involved.

"If you are always there for that person and they are never there for you, you are probably in a one-sided friendship," she told INSIDER. "Great business partners refer business to you and promote your products and services even when they have no financial gain. True friends do this too. They are often more excited about your achievements than you are and tell everyone they know about the great things you do. A major red flag is a friend that tries to steal your joy or becomes a 'Debbie downer' when you receive recognition."

You have to hide who you truly you are.

Any relationship or friendship that you have should enable you to be your best self all times. According to Gayle Johns-Carter, professional life coach and founder of Coaching Your Life's Goals, you should never feel pressured to be someone you're not around your true friends.

"If you are constantly feeling pressure to impress your friend, then that's not a friendship," Carter said. "My work as a Life Coach centers around one being their authentic self. I often work with clients in building a framework of self-discovery and self approval which allows the client to be able to ascertain if the relationships are real and, where you can just be who you are uncensored."

You make continued excuses for their poor behavior.

Carter also told INSIDER that toxic friendships center around making excuses for your friends that have poor behavior.

"When your friend has missed every major event in your life giving you excuse after excuse for not being there to support, this is a good way to know that this is a toxic friendship," Carter said. "Continuing to accept these excuses is how you know that they have manipulated you into believing that their friendship is genuine."

Michael Jordan made less than $100 million as the NBA's greatest player of all time, but is now a member of Forbes' list of billionaires with an estimated net worth of $1.65 billion.

Since Jordan retired 15 years ago, he has built the most successful and lucrative career we've ever seen from a former athlete.

From sprawling houses to custom planes to his own golf course, he's clearly enjoying life after hoops.

Jordan still makes more money than LeBron James, Stephen Curry, Kevin Durant, or any other active player.

He reportedly makes $100 million a year from Nike royalties alone. LeBron is estimated to make less than $90 million a year, including salary and endorsements.

Over the past 15 years, the landscape of television has changed drastically, but one show has been there through it all: "NCIS."

Through three presidents, two decades, and many drastic cast changes, "NCIS" has consistently remained a ratings powerhouse. It's been the most popular show on TV for years, and its stars are consistently fan favorites. Not surprisingly, it was renewed for a season 16 in April 2018.

Throughout its 350 episodes, some familiar faces have come into the team's orbit, like Michelle Obama, Zac Efron, Abigail Breslin, and Millie Bobby Brown. Keep scrolling to see if you can remember 15 seasons worth of famous guest stars.

Warning: Spoilers ahead for those who haven't watched all 15 seasons.

Michelle Obama cameoed as herself to promote her charity Joining Forces, an organization dedicated to supporting service members, veterans, and their families.

One of the executive producers of "NCIS," Gary Glasberg, revealed an important milestone about the episode. "We're the first dramatic film production to actually film in the White House," Glasberg said.

Just three days before "High School Musical" premiered, Zac Efron appeared in a season three episode.

Efron's episode, "Deception," aired on January 17, 2006. Three days later, on January 20, pop culture was forever changed when "High School Musical" premiered on the Disney Channel, spawning two sequels and a nation-wide tour.

Jamie Lee Curtis has appeared in multiple episodes as Dr. Samantha Ryan, one of special agent Leroy Jethro Gibbs' girlfriends.

Curtis and Harmon (Gibbs) had played love interests before — in 2003 comedy "Freaky Friday."

One of the best announcements that came out of this year's Google I/O was a new Gmail feature called Smart Compose, which can autocomplete entire emails for you.

• Flights require a particular set of items if you want to remain comfortable and relaxed.
• The more you travel, the more you learn what to pack — and what to leave behind.
• Author Natalia Lusinski has taken 15 flights in the past year, and these are the items she never travels without.

As someone who has taken 15 flights in the last year, there are several items that are must-haves when traveling. Of course, it’s a learn-by-doing process, but I’ve finally distilled my carry-on bag to a compact assortment of essentials.

Each time I step foot on an airplane, I bring with me what I like to call my “plane kit.” The kit is an assortment of smaller items grouped together in a makeup bag that I take from flight to flight. This way, I don’t have to keep repacking my flight essentials and am sure that everything I need is in one, easily accessible place.

Here are 17 items I’d never travel without.

SEE ALSO: I'm taking a trip around the world with only a carry-on suitcase — here's everything I packed

1. A comfortable hoodie

Planes often seem to be too hot or too cold. A hoodie can keep you warm if your airplane is uncomfortably cool, and if not, you can use the hoodie as a cushion to sit on, a germ barrier between you and the headrest, or a pillow.

2. Earplugs

Nothing’s worse than wanting to take a nap on a flight, only to realize there’s a crying baby behind you. Maybe you want to catch up on work and need to drown out ambient noise. Whatever the case may be,traveling with earplugs is a must.

3. An eye mask

Whether you want to get some sleep or just want to relax without being disturbed, an eye mask’s got you covered — literally. When I flew Etihad Airways to Australia last year,they gave out eye masks with messages that said “Do not disturb” on one side and “Wake me up to eat” on the other. Genius.

• A pandemic disease could be the greatest threat humanity faces right now.
• The WHO and CDC each keep lists of diseases that they consider urgent priorities for more research, but the next pandemic could be caused by a disease people have never seen before.
• For now, though, these are the six diseases that worry experts the most. 

For scientists that study disease, one unnerving fact is always present: somewhere on the planet, there's an organism or organisms — likely bacteria or a virus — that could kill tens of millions if it started to spread among people.

Pathogens we've never seen before lurk around the world, potentially living in bats, mosquitoes, or ticks, and waiting to jump to humans. Existing diseases mutate, becoming deadlier or more contagious. People are even growing more capable of modifying deadly diseases on their own.

Many experts think a global pandemic disease, whether naturally occurring or engineered, is the greatest threat humanity faces right now.

Bill Gates, who provides significant funding for disease research through the Bill and Melinda Gates Foundations, has repeatedly emphasized that we're not adequately prepared for the next pandemic illness. Recently, he warned that an outbreak of a disease like the flu virus that swept the world in 1918 could kill 30 million people within a six-month time span.

"The world needs to prepare for pandemics in the same serious way it prepares for war," Gates said at a recent discussion about epidemics.

The Centers for Disease Control and Prevention (CDC) keeps lists of the diseases that pose national security threats as possible biological weapon agents. The World Health Organization (WHO) also lists priority diseases that they think could become public health emergencies.

Here are some of the diseases that keep those experts awake at night.

The flu

The deadliest epidemic the world has ever seen took place 100 years ago, when the 1918 pandemic influenza virus blazed around the world. It infected  500 million people — a third of the world's population — and killed between 50 and 100 million people. 

In a normal year, the flu kills between 291,000 and 646,000 people around the world, according to the CDC. Experts think that if a new deadly flu like that 1918 pandemic virus were to emerge now, it would spread rapidly enough to kill almost 33 million people within six months.

Researchers have conducted experiments to see if it would be possible to make contagious flu strains deadlier or deadly flu strains more contagious. Those are viruses that no one ever wants to see in the wild.

Ebola, Marburg, Lassa, and other viral hemorrhagic fevers

Viral hemorrhagic fevers are spread by a variety of viruses and are mostly untreatable. They affect many organs and damage blood vessels, sometimes causing internal and external bleeding.

Infections often cause fever, weakness, soreness, and headache, often followed by vomiting, diarrhea, rashes, organ failure, and bleeding.

These diseases regularly emerge from the wild, as Ebola did again just recently. They can be extremely deadly — in past Ebola outbreaks, fatality rates ranged between 25% to 90%, with an average of about 50%.

Hemorrhagic fevers feature on both the CDC's list of biological agents that could pose a national security threat and on the WHO's list of diseases that can cause a public health emergency, and for good reason.

The 2014 Ebola outbreak in West Africa infected more than 28,600 people and killed more than 11,300. Such outbreaks can also cause public terror. Experts widely agree that the world needs to develop better ways to contain diseases like this. In the case of Ebola, researchers are testing an experimental vaccine to see if it can help stop the current outbreak.

If a strain of this type of disease were to mutate or be modified to become more contagious, that could cause worldwide devastation.

Coronaviruses like MERS and SARS

Coronaviruses are commonly found around the world, living in species like bats and camels. They take their name from crown-like spikes on the virus' surface.

For years, they were thought to be mostly innocuous. But in recent years, two coronaviruses that cause severe and potentially deadly respiratory symptoms in humans started to spread.

In 2002, SARS (severe acute respiratory syndrome) infected 8,000 people, killing approximately 10% of those patients. MERS (Middle Eastern respiratory syndrome) started infecting humans in 2012. While it is less contagious than SARS, it's more deadly, killing about 30% of those infected.

Most patients with these conditions first show signs of fever and many have gastrointestinal issues. These symptoms are often followed by shortness of breath and pneumonia.

This type of transition shows how quickly a new illness can emerge or transform to become a new public health threat — a process that regularly occurs. The WHO says there is an urgent need for research into ways to prevent the spread of these diseases.

The Insider Picks team writes about stuff we think you'll like. Business Insider has affiliate partnerships, so we get a share of the revenue from your purchase.

The Insider Pick:

• Natural toothpaste formulas don’t have to be lacking in powerful ingredients or great flavor. Take our top pick, Desert Essence Natural Tea Tree Oil and Neem Toothpaste, for example. It cleans teeth and keeps breath fresh, thanks to naturally occurring tea tree oil, neem, baking soda, and sea salt.

Brushing your teeth is an intimate thing. And yet, we don’t tend to give our toothpaste selection careful thought. Most of us just go to the drugstore, pick up whatever is on sale, and go on our merry way. Can you even tell me what brand is in your medicine cabinet right now?

Now more than ever, buyers interested are interested in ingredients. They want to know what’s in their products, and why. Although there is a significant amount of debate about what really counts as “natural” and whether “natural” is automatically preferable to synthetic formulations, more and more people are making the switch to products that use all or mostly natural ingredients.

Maybe you’re here because you’ve already overhauled your skin care, cosmetics, cleaning supplies, and deodorant to include only natural products, and toothpaste is just the next item on your list. Or perhaps you simply want to learn about the alternatives to whatever is currently sitting on the shelf in your bathroom.

But first, a note about fluoride: Though some people prefer to avoid it, there are several options in our guide that do include the ingredient. As Allurepoints out, “contrary to what many believe, fluoride is natural.” It’s “found throughout the earth's crust, in rainwater, in plants, and it's the only ingredient that is proven to reduce cavities," as dentist Caroline Barsoum told the publication.

Still, some people don't want fluoride in their toothpaste, so if you prefer to do without fluoride, there are some options for you in our guide, too.

Here are our top picks for the best natural toothpaste:

• Best overall: Desert Essence Natural Tea Tree Oil and Neem Toothpaste
• Best with activated charcoal: Schmidt’s Activated Charcoal Tooth and Mouth Paste
• Best for sensitive teeth: Hello Sensitivity Relief Fluoride Toothpaste
• Best fluoride-free: Tom’s Antiplaque Whitening Fluoride-Free Toothpaste
• Best for kids: Hello Kids Fluoride-Free Natural Watermelon Toothpaste
  

Read on in the slides below to check out our top picks for the best natural toothpaste.

The best natural toothpaste overall

Why you'll love it: Thanks to its natural ingredients, Desert Essence Natural Tea Tree Oil and Neem Toothpaste keeps your mouth clean and healthy.

Desert Essence Natural Tea Tree Oil and Neem Toothpaste appears on tons of “best natural toothpaste” lists and has racked up tons of rave reviews on Amazon. Why? Because it’s effective but lacks most of the ingredients you probably came here to avoid.

This toothpaste is mentioned all over the internet as a top natural toothpaste — it has 1,200 Amazon reviews (75% of which give the product 5 stars!) and earns high marks from experts as well. Good Housekeeping, Ask a Dentist, and Apartment Therapy all include it among their picks for the best natural toothpaste.

Tea tree oil is the hero ingredient, and it's said to be antibacterial and freshen your breath. Good Housekeeping did note that its testers didn’t love the flavor of this toothpaste, so if you’re really sensitive to taste, you may want to read on for other options.

In a review, Anna Hoffman of Apartment Therapy wrote, “Overall, I really liked this toothpaste — it tasted pretty good and was effective at keeping my mouth as fresh and non-swampy as my normal drugstore toothpaste.”

Pros: Natural ingredients, contains antibacterial tea tree oil

Cons: No fluoride, “earthy” flavor

The best natural activated charcoal toothpaste

Why you'll love it: Don’t let the color of Schmidt’s Activated Charcoal Tooth and Mouth Paste fool you — This is an excellent whitening toothpaste that tastes minty fresh.

Natural deodorant company Schmidt’s recently added toothpaste to its roster of products, and I’ve personally had the chance to test out a few of the flavors. My favorite is the Activated Charcoal Tooth and Mouth Paste. It comes out of the tube a disconcerting shade of dark grey, but it’s worth overlooking the initial shock because of the whitening benefits.  

I get bad stains on my teeth, which are partially due to the texture of my tooth enamel and partially due to my insistence that water and coffee are interchangeable substances. This toothpaste lessened the impact of those stains so much that my mom noticed without me even mentioning it, which is pretty much the highest compliment I can give it.

My teeth stayed even noticeably lighter after I moved on to using a formula without the activated charcoal. Schmidt’s Activated Charcoal Tooth and Mouth Paste is formulated with COQ10, vitamin E, and goji berry and pomegranate extract, and is vegan and cruelty-free.

The brand’s toothpastes are pretty new so they only have a few online reviews. Fast Company writer Rina Raphael gave them a mostly positive assessment, though she was initially put off by the grey color of the activated charcoal toothpaste.

The two buyer reviews on Amazon both give the toothpaste 5 stars. “I love this toothpaste,” says one fan. “It has a smaller amount of charcoal than some others. I like that. It still does a great job, but it is less messy. And...my teeth feel so clean!

Pros: Nice minty flavor, whitening activated charcoal, cute packaging

Cons: Toothpaste is dark grey and will stain your sink if you don’t rinse thoroughly after brushing

The best natural toothpaste for sensitive teeth

Why you'll love it: Got sensitive teeth? Hello Sensitivity Relief Fluoride Toothpaste is packed with soothing ingredients and lacking in dye, artificial flavor, parabens, and SLS.

Toothpaste for sensitive teeth doesn’t tend to inspire medicine cabinet envy — The packaging is often clinical and unattractive. But Hello Sensitivity Relief Fluoride Toothpaste is the exception. The metallic pink tube looks great next to all your fancy face creams, while the formula delivers soothing ingredients and a fresh, minty taste.

There’s so much to love about Hello Sensitivity Relief that it’s hard to know where to start. It has all the great benefits you get from the brand’s other formulas, like teeth whitening and cavity fighting, plus the addition of desensitizing ingredients like aloe vera, xylitol, and coconut oil (commonly used in a dental care technique called oil pulling).

Then, there are all the things this toothpaste doesn’t have: parabens, artificial dyes or flavors, sodium lauryl sulfate (SLS), gluten, preservatives, etc. Additionally, all Hello products are cruelty-free, vegan, and packaged in boxes “made from 100% recycled paperboard and printed with soy inks.”

Allurenames Hello Sensitivity Relief as a great pick in an article on natural toothpaste, and it has a 4.4 rating on Amazon based on 326 customer reviews. “Truly the best toothpaste available,” writes one fan. “I started using this toothpaste 6 months ago because I have terribly sensitive teeth and my teeth feel the best they've ever been.”

Pros: Contains soothing and moisturizing ingredients for sensitive teeth, cruelty-free, comes in recycled packaging, no SLS, contains fluoride

Cons: Contains fluoride

• Amazon is the one-stop shop to buy everything from fresh groceries to clothes and furniture.
• Walmart-owned Jet.com sells many of the same products as Amazon, though on a smaller scale.
• Jet competes in a number of ways, including by offering free two-day shipping on orders over $35.
• We compared what it's like to shop on Amazon and Jet and found that they each had advantages. Overall, we found Jet to be more shopper-friendly. 

Amazon has become the go-to store to buy, well, everything. 

Amazon has made it possible to order everything customers might need, including groceries, clothes, and furniture, all in one place. For $12.99 a month or $119 a year, Prime members get added bonuses on top of the frequent markdowns, like free two-day shipping and access to music and video streaming services.

But Walmart-owned shopping site Jet has been making strides to compete with the e-commerce giant, like offering daily deals and free two-day shipping without membership fees. Though Jet can't compete with Amazon when it comes to certain exclusive products like Echo devices, Kindles, and streaming services, it offers JetCash, which are rewards incentives that can be used as cash on the site. It also has a private-label brand called "Uniquely J," which is designed to attract millennials by creating environmentally friendly products in artist-designed packaging. 

Even though products are sometimes listed in different quantities or under different categories, the websites have a huge overlap in what they sell. To see which of the two stores had better deals and was more user-friendly, we compared common items from different categories on each site to see which site had better deals, which site had better shipping and returns policies, and how easy each website was to use.

The prices were extremely similar on Amazon and Jet, but one of the online stores had a few clear advantages — see how they stack up:

SEE ALSO: We compared prices on best-selling items at Amazon and Home Depot to see who has the best deals on tools and paint — here's the verdict

The differences between Amazon and Jet were obvious right away. The Amazon homepage featured deals and products that were recommended based on products I've looked at before, alongside a Prime advertisement and other related ads. There were a ton of recommended products and drop-down menus.

Jet's homepage was much simpler. Fewer products were displayed, and there was nothing showing up based on other products I've viewed in the past. There were fewer menus to choose from, so I was less overwhelmed with options. The layout was pretty similar to Amazon.

Both sites had a ton of different categories, including fresh produce, electronics, clothing, makeup, and more. It was a bit of an information overload.

Royal engagements can involve members of the royal family meeting world leaders and dignitaries, giving speeches to support charities, or going on "walkabouts" where they greet members of the public.

Sometimes, though, royals get to have a little bit of fun and show off their athletic prowess — albeit while very overdressed.

Here's what it looks like when present and future monarchs play sports.

• Office life has undergone a number of major changes since the 1950s.
• Of course, workplaces have always varied in terms of look and culture, oftentimes based on regional, industry-wide, or organizational norms.
• But there have also been a number of widespread changes overtime.
• These shifts include increased workforce diversity, widespread bans on smoking, and changing trends regarding popular workplace layouts.

Office culture has changed quite a bit over the years.

Some of those shifts were actually reflected in workplace design trends.

Corner offices were meant to convey hierarchical prestige and status. The cubicle was intended to improve employees' lives, but ultimately became a symbol of corporate drudgery. And the currently-popular open office layout was introduced as a more egalitarian approach, but has received quite a backlash, as well.

In his 2014 book "The Best Place to Work: The Art and Science of Creating an Extraordinary Workplace," Ron Friedman concludes that the jury's still out on which style is the least terrible option.

"Cubicles are depressing. Private offices are isolating. Open spaces are distracting," he writes.

But the big changes to US work culture haven't just been all about appearances.

Teamwork is ostensibly in, while hierarchy is out. Typewriters got the boot with the advent of faster, user-friendly computers. Corporate jargon and ideas about job security have gone through major fluxes, as well.

Racial diversity in the workforce has increased overtime — although many fields still have quite a way to go.

And workplace sexual harassment has gone from being a pervasive and widely-accepted phenomenon to a pervasive but somewhat less widely-accepted phenomenon.

Let's take a look back in time at how office culture has changed over the years:

In the years following World War II, Friedman wrote that most offices "... consisted of a vast open space, with rows and rows of identical desks crammed tightly together."

This "bullpen office" had blue-collar roots, according to Friedman. The open design hearkened back to the factory floor, and was meant to foster productivity by keeping everyone visible.

Of course, not everyone would have been stuck in the bullpen. At some companies, high-ranking employees might receive their own office.

• DSW, in an effort to take on retail giants like Amazon-owned Zappos, is shaking things up with a brand new look and revamped rewards program.
• We visited DSW’s “lab store” in Columbus, Ohio to check out the new in-store features, which include a concierge area for shoe repair, a full-service nail salon, and so much more.

In response to the growth of online retailers like Zappos and its parent company, Amazon, shoe and accessories giant DSW has unveiled plans to completely revitalize its in-store shopping experience.

In the last year, DSW’s business had its high points, including three consecutive quarters of positive comparable sales in footwear, according to its March earnings report. But it wasn’t all smooth sailing. Sales and earnings took a dip in the fall of 2017 — causing the company's stocks to do the same. CEO Roger Rawlins attributed this to “an unusually severe hurricane season” in an earnings release.

But the company is determined to win back customers who enjoy the convenience of online shopping, Rawlins and Simon Nankervis, DSW’s chief commercial officer, told Business Insider. DSW plans to achieve this by adding new in-store features, including a brand-new store design that blends fun with functionality, a concierge area for shoe repair and shoe donation, a full-service nail salon, as well as an overhaul of its rewards program (which currently boasts 25 million members, according to a press release announcing the revamp).

Business Insider visited DSW’s “lab store” in Columbus, Ohio, to see the changes in person.

The DSW in Columbus, known as the Polaris store, is close to the company’s headquarters and is one of its largest stores, with space for more than 70,000 pairs of shoes.

At DSW, shoppers will notice a new look as stores undergo remodelling. Nankervis told Business Insider that the sleek new design will no longer look like a chaotic “sea of shoes,” but instead make their stores inviting. New displays will showcase more available in-store merchandise, with shelf space for 50,000 pairs of shoes instead of the previous 30,000.

DSW is looking to provide a lively yet relaxing in-store experience by streamlining the browsing process.

The company is bringing its original concept of a shoe warehouse back to life, but elevating the experience so that shoppers can get what they want without losing the fun of shoe shopping.

Clearer signage, brighter lighting, and reverting to the original warehouse design will allow customers to peruse the items more easily.

Customers can shop their favorite brands all in one place at DSW’s shop-in-shop sections.

The Polaris store currently features a shop-in-shop display by Nike, which is a fully separate section devoted to Nike merchandise. By changing out these shop-in-shop displays monthly, consumers can quickly access their favorite brands while shopping styles exclusive to DSW.

These displays will be changed out monthly in each store, highlighting the newest and most popular styles from top brands, Nankervis said.

The ongoing volcanic eruptions on Hawaii's Big Island have caused severe damage to residential neighborhoods surrounding the Kilauea volcano.

The eruptions are showing no signs of slowing down. On Tuesday, the United States Geological Survey (USGS) issued a rare "red alert" warning, which means a major eruption is imminent and that the ash clouds emitted from the volcano can affect air traffic.

The volcano continues to belch noxious fumes, like sulfur dioxide, which can make breathing difficult for children and the elderly. Geologists are also warning that the eruption may enter a more violent stage, spewing lava and hurtling boulders hundreds of feet in the air.

Neighborhoods in the volcano's vicinity have been hit particularly hard by the eruption, and over 1,000 people have evacuated. 

DigitalGlobe, a technology firm that operates a network of private satellites, provided Business Insider with a series of satellite images showing the damage  from the eruptions. Below, photos of the affected neighborhoods from 2017 are juxtaposed with images taken this week of the same area. 

Here are the before-after-photos of the damage:

The Leilani Estates neighborhood in Kilauea's East Rift Zone has sustained the worst damage from the eruption. The area is pictured here on May 24 of last year.

In Leilani Estates and surrounding neighborhoods today, lava is spewing from 20 fissures, or cracks in the ground. It has burned houses, vehicles, and infrastructure.

Leilani Estates is a populous subdivision with almost 2,000 residents. Here's another view of it in 2017.

OnePlus revealed its latest smartphone — the OnePlus 6 — on Wednesday during an event in London. 

With the new model, you're getting the latest specs for 2018 and some new design elements,  but overall, the OnePlus 6 is a minor update from its predecessor, the OnePlus 5T.

OnePlus has consistently offered top Android specs and performance for significantly lower price tags than the competition from big names like Samsung, Apple, and LG. It appears to be the same for the OnePlus 6, but the company has slowly been raising the price after every new release over the last few years. 

The OnePlus 6 starts at $530 in the US, and it'll become available to buy starting on May 22. 

We spent some hands-on time with the new phone — check out our first impressions of the OnePlus 6:

Here it is, the OnePlus 6.

Inside the OnePlus 6 are all the specs you'd expect and find in a premium, high-end Android smartphone in 2018. That includes:

- The latest Snapdragon 845 processor from chipmaker Qualcomm for speedy performance. 

- 6GB to 8GB of RAM for running lots of apps in the background and keeping performance smooth.

- A large 6.28-inch display.

- A premium design with narrow bezels around the display.

- A dual-camera system.

- Facial recognition to unlock the phone. 

- Quick charging. 

- A decently large 3,300mAh battery. 

There might be a couple specs that could put you off, but they really shouldn't.

Eagle-eyed readers might notice that OnePlus is sticking to a 1080p resolution for its displays compared to the 1440p resolution you'll find on most high-end Android phones. That means the OnePlus 6 doesn't match other high-end Android phones in screen resolution, but it was never a problem during my short time with the device so far. In fact, I never even noticed that it was a lower resolution than the 1440p Galaxy S9 Plus I've been using recently. 

You might also notice that OnePlus still hasn't obtained official water resistance ratings for the OnePlus 6. However, the company is confident that the OnePlus 6 can resist common water splashes, like rain. 

And yes, it has a notch.

The notch was confirmed before the OnePlus 6's announcement by the company's co-founders. So anyone who was interested in buying the new OnePlus phone had some time to get used to the idea if they don't like the notch on other devices, like the iPhone X. 

Russian President Vladimir Putin said Tuesday that 14 Russian missile regiments would receive the new Yars RS-24 intercontinental ballistic missile systems amid a possible growing arms race with the US. 

"Pursuant to provisions of the state program for armaments, we'll continue replacement of the outdated Topol missile complexes with the newest Yars systems and will put them on the tables of equipment at fourteen missile regiments," Putin told defense industry officials in a broader push to modernize Russian forces and weaponry, according to TASS.  

The Yars is a three-stage ICBM that can be fired from mobile-launchers and silos. It was successfully tested in September 2017 when it was fired from a mobile-launcher from Plesetsk to the Kura range site in Kamchatka Krai.  

Russia had also said that it test fired a silo-based Yars ICBM with an "experimental warhead" a few days before that. 

"It is not clear what these new 'experimental' Russian reentry vehicles (RV) are," The National Interest reported at the time, adding that it's possible that it was a maneuverable reentry vehicle designed to elude missile defense systems. 

Here's what the Yars RS-24 ICBM can do.
