Antarctica has two adjacent ATMs installed by Wells Fargo in 1998 to serve the population of McMurdo Station, a research facility that houses up to 1,000 people and is run by the National Science Foundation as part of the US Antarctic Program.

ATMs drastically expanded access to checking accounts in the 1960s

The invention disrupted the local bank industry, allowing customers to access cash around the clock and when out of town. The innovation also reduced the headcount needed for bank services and created a new revenue stream via ATM fees for noncustomers. This 50-year anniversary retrospective revisits the cash kiosk.

The Antarctic Circumpolar Current is Earth's most powerful ocean current and carries more than 100 times the combined flow of all Earth's rivers.

The robust wine production of Antarctica

Antarctica might not be known for its agriculture, but parts of its unique climate are suitable for growing wine grapes. Most of the wine produced there is icewine, a style of dessert wine commonly found in Canada and Germany. This guide covers Antarctica’s unique soil composition, grape varieties, and how exactly penguins contribute to this unusual wine-growing region. There’s even a recommendation for an Antarctic tasting room for adventurous souls.

Alaska's sovereign wealth fund pays people to live in the state through an annual dividend

While the US doesn't operate a federal sovereign wealth fund, several states run SWFs—the most well-known being the Alaska Permanent Fund. Unlike most SWFs, the Alaska Permanent Fund sends cash payments averaging roughly $1.2K each directly to Alaskan residents each year.

American Express intentionally targets wealthy cardholders, who spend higher amounts per transaction and tend to make more transactions than the average cardholder, thereby reducing the company's risk.

Two of American Express' co-founders also founded Wells Fargo

Henry Wells and William Fargo formed Wells, Fargo & Co. two years after American Express was created. Wells and Fargo saw an opportunity to expand the express delivery service from the East Coast and Middle America to the West Coast. The two initially asked the American Express board to expand operations, but the board declined, so they decided to create their own company. Today, Wells Fargo is among the top four largest banks in the US.

Track the current size of the Antarctic ozone hole with NASA's real-time data

The town of Churchill has a population of 850 humans and just as many polar bears. In an effort to prevent hungry bears from breaking into homes or attacking residents, the town began imprisoning them for 30-day stints.

American Express is both a card issuer and a processing network

Unlike most credit card companies, American Express issues credit cards and processes payments—something called a closed-loop model. By offering both services, American Express profits from both interest and interchange fees, and also has access to more data on how customers spend their money so it can offer better perks.

Studying the circadian clock of a tiny swimming polar creature may help forecast polar ecosystem health

A 2025 study found that Antarctic krill, a food chain staple in the Southern Ocean, have an internal biological clock that helps regulate its swimming patterns and helps the tiny shrimp-like animals adapt to daily and seasonal environmental changes. Better understanding of how the clock and light cues interact may help scientists understand how well the species will respond to pronounced climate change in the polar region.

The 6 US Mint locations across the country work together to create America’s coins and more

While the US Mint at Denver makes circulating and collectible coins, the US Bullion Depository at Fort Knox stores much of the country's gold. Other locations include the San Francisco Mint, the Philadelphia Mint, the headquarters of the US Mint in Washington, DC, and the West Point Mint.

Why the Antarctic climate enabled British scientists to discover the ozone hole

In the Antarctic stratosphere, polar conditions facilitate the formation of polar stratospheric clouds, which allow chlorine compounds from chlorofluorocarbons to accumulate. In 1985, British Antarctic Survey scientists detected massive springtime losses over Antarctica, as accumulated compounds destroyed significant amounts of ozone once sunlight returned.

The United States had a washing machine that cleaned dirty dollar bills

In the early 1900s, the US Treasury Department had a machine that washed and ironed old, soiled paper bills. The machine helped the Treasury save money by decreasing printing costs for new dollar bills, but had nothing to do with the modern understanding of money laundering.

In 1882, American Express began offering money orders to compete with the US Postal Service

Money orders were American Express' first move into financial services. USPS launched its money order service in 1864 as a way for Civil War soldiers to send money back home. Between the 1880s and 1920s, immigration into the United States surged;the American Express money order service gave immigrants a way to send money to family members living in other countries.

Alaska's 750,000 residents are fed by $2B in food imports annually

Deep Space Network sites enable nonstop communication with distant spacecraft

Each DSN complex has multiple large, sensitive antennas that can receive weak radio signals from far-off spacecraft and send commands back to them. Their amplifiers are cooled to just above absolute zero to reduce electronic noise.

American Express is credited with inventing the traveler's check

In the 1890s, then American Express President James C. Fargo was frustrated that he couldn't get cash while traveling in Europe outside of major cities. Marcellus Berry, an American Express employee, came up with the idea of a traveler's "cheque": a prepaid check, similar to cash, that requires the signature of both the customer and the receiving institution to be valid. American Express never modernized the spelling of the word "cheque" and stopped providing them at the end of 2020.

Up to to $68M in coins ends up in American landfills each year.

Waste facilities and TSA say they collect thousands of dollars of discarded money per year. A Wall Street Journal reporter visited a waste facility and learned what you can do with your extra change.

Gas stations top the list of riskiest places to use a debit card

Unlike credit cards, debit cards withdraw funds directly from your checking account, and federal laws provide fewer consumer protections against debit fraud. Gas station "skimmers" and long periods of separation from the card at restaurants are some of the more vulnerable spots for use.

The Deep Space Network is an array of giant radio antennas at three locations on Earth to keep NASA in constant communication with spacecraft billions of miles away.

American Express runs on a 'spend-centric' model, using perks and merchant fees to drive profit

American Express cardholders tend to spend more money per transaction than other credit card users, which makes the interchange fees merchants have to pay to accept American Express cards worth it while incentivizing other companies to pay the interchange fee as well.

The mysterious Fort Knox houses much of America’s gold reserves

This fortified vault, built in 1936, is part of the US Mint, but it doesn’t create any currency. Only a presidential order can open Fort Knox—there has not been an audit of its contents since 1953.
