How scientists know invasive nutria were likely introduced to California by humans

Although native to South America, DNA testing of the semiaquatic rodents showed they are closely related to a population in Oregon, suggesting they were deliberately transported into the state. First identified in the San Joaquin Valley in 2017, the distance, terrain, and lack of nutria between the two regions has allowed researchers to rule out natural migration.

Visualizing California's wine production

While Europe has France, Italy, and Spain, the US has California. The bulk of US wine production takes place in the Golden State, accounting for roughly two-thirds of the United States’ nearly 800 million gallons produced each year. This chart compares California and United States wine production from 1995 through 2022. Production in both has been trending down for several years, partially due to extreme weather events.

How winemaking has changed throughout history

Winemaking is an ancient practice, and researchers continue to find evidence that this ritual came even earlier than previously estimated. This article outlines five key turning points in wine’s history, from the fermentation of fruit by our primate ancestors to today’s increasingly popular “New World” wine. Discover the fascinating scientific and cultural factors that led to wine’s changes in flavor and increased symbolic importance.

Volcanoes in the 1340s likely helped trigger the Black Death

The "bubonic plague" that wiped out roughly half of Europe and Asia originated from many factors. Recent research suggests volcanic eruptions contributed as well. The "aerosol" effects of matter released from eruptions likely prompted famine and accelerated the spread of infected fleas riding on grains avoiding spoilage.

Volcanic activity may have triggered the Black Death by spewing gases that led to crop failures in Europe, thus forcing the import of grain ships with plague-infested fleas.

European diseases killed a massive share of the Native American population

After Western contact, epidemic diseases devastated Indigenous communities. By 1920, the Native American population of the US had fallen to roughly 270,000, compared with an estimated 1.2 to 18 million at the time of European arrival.

There's a legal loophole behind California Champagne

In the late 19th century, sparkling wine production took root in California before France began the fight to own the term “Champagne.” Many American winemakers already used it for easy recognition. The battle continued for over a century before reaching an agreement in 2005, stipulating that American sparkling wine couldn’t be labeled as Champagne unless the producer was already calling it such.

Champagne played a role in resisting the Nazis

When France surrendered to the Nazis in 1940, the invaders occupied the north. This was home to wine regions like Champagne and Bordeaux, which the Nazis were eager to loot. Winemakers took a stand by sheltering dissidents in their cellars, passing intelligence across borders, and even giving their lives to the cause.

The numbers on US wine consumption

Ever wonder how much wine the average American drank in 1949? Wonder no more! The answer is 0.89 gallons. That’s way less than 2022, where the number has quadrupled to 2.86 gallons. Check out this simple table that tracks average United States wine consumption from 1934 through 2022, by individuals and as a whole. American wine consumption peaked during the early pandemic but has lessened since then.

Wine explained

Wine is the sublime product of fermentation, the process of breaking down fruit—typically grapes. As the grapes ferment, yeast consumes the natural sugars and converts them to alcohol. With the process first developed and refined thousands of years ago, wine has been a central feature of celebrations throughout modern history. Want to learn more about its origins?

In 1951, a small French town was likely overtaken by the fungus that ultimately led to LSD.

Champagne’s fizz used to be considered a flaw

The bubbliness that we love now was once considered a winemaking failure. In fact, Dom Pérignon probably would have referred to it by its common nickname at the time, "vin du diable," or devil’s wine. The wine’s volatility often caused bottles to explode, which was both dangerous and costly. It wasn’t until the development of sturdier bottles and more consistent winemaking techniques that popularity truly soared.

Europeans' arrival to America brought disease to Indigenous populations

Indigenous people lived in the Americas for centuries before the arrival of the first Europeans in the 15th century. Their arrival was disastrous for Native tribes; in addition to being enslaved and losing their land, they had no natural immunity to the diseases brought by colonists. Eventually, up to 95% of the Native American population was killed by illnesses including typhus, chickenpox, and cholera, an event now known as the Great Dying.

Nearly 5,500 crows died during four months in 1999 from West Nile in NYC.

Why your wine smells unpleasant

Ever had the experience of receiving a bottle of wine with a janky, less-than-favorable odor? This Esquire article ventures to answer this question and offers the explanation that the culprit is likely corked wine.

The American cockroach is actually from Africa—an apparent hitchhiker aboard ships carrying enslaved people—with evidence suggesting it may have arrived in the New World as early as the 1600s.

Poison ivy was sent to Europe in the 1600s as an exotic, ornamental oddity.

Fungi have been used to restore island habitats in the central Pacific

After removing 1.5 million invasive coconut palm trees and eradicating the black rats that fed on them, as well as seabirds and crabs, conservationists working with the US Fish and Wildlife Service identified areas where fungi could be transplanted to provide nutrients to native trees. These trees serve as nesting sites for seabirds whose guano nourishes coral reefs.

A history of Rome and wine

Wine and winemaking were integral parts of everyday Roman life. Wine was used medicinally and for religious rites, as well as for pleasure. It also contributed to the expansion of the Roman empire as wine and grapes were traded throughout the Mediterranean. Roman winemaking practices spread as the empire grew. Without Rome, wine may never have grown into what it became, and vice versa.

Mapping the spread of a dangerous fungus growing in US healthcare facilities

Explore the data showing how the fungus C. auris has spread in the US, with more than 10,000 reported cases since 2016. Recommended steps to prevent infections and limit their spread have been successful in some areas, but infection control remains complicated because the fungus is often now multidrug-resistant.

The canal carried germs as well as goods

In 1832, North America’s first cholera epidemic spread inland by way of the Erie Canal, carried by immigrants arriving on ships. Fearful towns barred passengers from disembarking, yet cholera, smallpox, and other diseases still traveled the waterway.

The use of fungi to detoxify land and water—a process known as mycoremediation—has been used to clean up natural resources affected by the 2025 California wildfires.

Hollywood's efficient response to the Spanish flu made it a filmmaking destination

In 1918, the Great Influenza epidemic killed more than 675,000 Americans. Los Angeles was one of the first cities to shut down movie theaters, most of which were independently owned and couldn’t afford the revenue loss. The results were twofold: the quick response meant that Hollywood could bounce back faster than other film hubs, and it also contributed to the rise of vertical integration as studios stepped in to purchase the flailing theaters.

Santa Barbara County features seven designated wine regions

Grapes are notoriously fickle about where they grow and cannot be cultivated just anywhere. That’s what makes the county’s seven American Viticultural Areas so unique and cool—from the Santa Ynez valley to the Los Olivos District.

How a worm helped give the southern US its reputation

"The germ of laziness" that blanketed the southern US for centuries with unshakable fatigue, brain fog, and distended bellies paired with emaciated frames was actually a worm. This parasitic worm lives in the gut, where it can stay up to five years, laying up to 10,000 eggs daily. Hundreds of millions of people worldwide continue to suffer from hookworm infections, often obtained by walking barefoot across infected soil.

The ‘humongous fungus’ may be the largest organism on Earth at more than 2,300 acres

Discovered in 1988, when it was only covering 400 acres, this massive colony of Armillaria ostoyae, based in Oregon, has taken hold among the tree roots of the Malheur National Forest. It consists of a vast network of unique long black filaments of fungal tissue called rhizomorphs that grow under the soil and infect tree roots, nourishing the fungus but killing the trees. Researchers believe this fungal growth dates back more than 8,000 years and currently weighs approximately 35,000 tons.

Recent research indicates leprosy was present in the Americas before European settlers

New research published in 2025 upended long-held notions that the disease was introduced to the Americas by European colonizers. Evidence of a lesser-known leprosy-causing bacterium was found in ancient human remains that date back 4,000 years.

Millions of honeybees are hauled yearly across the US to help pollinate farms

As indigenous pollinator populations dwindle, farmers increasingly rely on commercial honeybees, which truckers often transport during cooler periods to prevent die-off from overheating. Pollinating all the almond trees in California requires 85% to 90% of all honeybees available to pollinate in the country.
