The researchers studied a wetland shaped by Eurasian beavers in Switzerland.

Beavers Are Ecosystem Engineers—and They Might Be Helpful Allies in the Fight Against Human-Caused Climate Change

New research suggests that wetlands created by the industrious rodents are carbon sinks, meaning they store a lot of heat-trapping carbon dioxide—the human-produced gas largely responsible for today’s global warming

Neanderthals survived from roughly 400,000 to 40,000 years ago, when they mysteriously disappeared.

What Killed the Neanderthals? New Research Suggests a Lack of Genetic Diversity May Be Partially to Blame

When the climate cooled, the population of Neanderthals shrank. Most that lived between 60,000 and 40,000 years ago were descended from the same lineage and had very similar DNA

In experiments, juvenile Atlantic salmon that were exposed to cocaine’s primary metabolite swam more and dispersed farther than their sober peers.

Cocaine Pollution Seems to Make Salmon Swim Farther Than Usual. Scientists Don’t Know the Long-Term Consequences

The illegal drug’s main byproduct, benzoylecgonine, caused more robust effects than cocaine itself. Wastewater treatment plants often don’t fully process such metabolites, so they are frequently found in bodies of water at higher concentrations than their parent drugs

The original King Taco location in the Los Angeles Cypress Park neighborhood is now a historic-cultural monument.

A Couple From Mexico Became Soft Taco Pioneers in Los Angeles 50 Years Ago. Now, Their Restaurant Is a Landmark

Raúl and Lupe Martinez opened King Taco and served up soft corn tortillas like they remembered from home. The rest is—now officially—history, thanks to a vote from the Los Angeles City Council

The Boyd Family Memorial Window (The Falls) by Tiffany Studios will be auctioned in New York in June.

This Dazzling Tiffany Stained-Glass Window Adorned a Church for More Than a Century. Now It Needs a New Home

The Second Congregational Church of Winsted in Connecticut will auction off the colorful artwork featuring a stunning waterfall and sunset

Scientists have long assumed that queen transitions in naked mole rat colonies were always chaotic and violent. But new research suggests another, more peaceful path also exists.

Naked Mole Rats Usually Duke It Out to Choose Their Next Queen. But These Unusual Rodents May Be Capable of More Peaceful Transitions of Power

In a laboratory experiment centered around a colony known as the Amigos, researchers observed a subordinate female take over reproduction without incident

Archaeologists found the historic structures while preparing for renovations at the Fox Tech High School campus, located in downtown San Antonio.

New Archaeological Discoveries Reveal How San Antonio’s Earliest Settlers Irrigated Crops and Accessed Drinking Water

While preparing for school renovations, researchers in Texas found remnants of the historic San Pedro acequia, a centuries-old technology that provided water to the burgeoning village

Amud 7 was discovered in a cave in Israel in 1992.

Neanderthal Kids Grew Up So Fast—at Least Compared With Their Human Peers—Thanks to Genetic Adaptations to Their Environment

Scientists think Neanderthal children may have had faster growth rates because larger bodies tend to retain heat more effectively than smaller ones

The reseachers investigated preserved specimens kept at museums, like this Bufoceratias wedli from the Field Museum in Chicago.

Anglerfish Are Known for Their Built-in Fishing Rods. New Research Sheds Light on How These Lures Evolved in the Strange Creatures

A new study suggests the odd appendages first appeared in the fish’s ancestors around 72 million years ago. Today, females might use them not only to attract prey but also to communicate with potential mates

The cave's floor is largely undisturbed, so archaeologists are hopeful it may help answer questions about the transition between Neanderthals and Homo sapiens in Britain.

This Medieval Castle Sits Atop a Prehistoric Time Capsule. New Excavations Could Reveal the History of Neanderthals in Britain

In a cave tucked beneath the Welsh landmark, archaeologists have found evidence of human and animal visits over the past 120,000 years. Now, they’re starting a five-year excavation project

Researchers found this hand ax, which appears to have been shaped around a geological feature imprint.

These Big-Brained Ancestors May Have Loved Crystals Just as Much as Modern Humans Do, According to New Research

Archaeologists in Israel unearthed prehistoric hand axes that Homo erectus crafted from stones including fossils and crystals, perhaps a sign that they wanted to connect with the cosmos

Grand Canyon National Park welcomes more than four million visitors per year.

Scientists Still Don’t Know How or When the Grand Canyon Formed. New Research May Hint at Its Ancient Origins

Researchers say the ancestral Colorado River formed an ancient lake in northern Arizona roughly 6.6 million years ago, which spilled out westward onto the landscape that would eventually become the Grand Canyon

As of April 10, 105 kakapo eggs had hatched, and 95 chicks were still alive.

A Bountiful Berry Harvest Put These Chunky, Endangered Parrots in the Mood. Now, Scientists Are Celebrating a Breeding Bonanza

New Zealand’s kakapo have laid 256 eggs, and around 100 of them have hatched, providing a bright spot in a decades-long conservation effort. The official chick count won’t be confirmed until the youngest birds are about 5 months old

Biologists with the California Department of Fish and Wildlife are working hard to eradicate nutria from the state.

Large Invasive Rodents Are Wreaking Havoc in California. New Research Suggests Someone Deliberately Introduced Them

Genetic testing revealed that nutria living in California since 2017 are most closely related to a population in central Oregon—too far for the creatures to have traveled on their own

The 125-foot-long Clough sank in September 1868.

A Sudden Squall Doomed This Stone-Hauling Vessel in Lake Erie. More Than 150 Years Later, Divers Just Found the Shipwreck

The “Clough,” a 125-foot-long bark, sank in September 1868 near Cleveland, with just one crew member surviving to explain what had happened

This illustration shows the size difference between a European pond turtle and the foot of a straight-tusked elephant.

Turtles May Have Been Tasty Snacks for Neanderthals 125,000 Years Ago. But Their Shells Were Probably the Real Prize

New research based on fragments discovered at the Neumark-Nord site in Germany suggests Neanderthals may have transformed the shells into tools

Nearly 200 hippos are estimated to roam in Colombia.

Colombia Plans to Euthanize Dozens of ‘Cocaine Hippos,’ Descendants of Animals Brought by Notorious Drug Trafficker Pablo Escobar

If nothing is done to control the invasive creatures, officials estimate the population could grow to 1,000 animals by 2035. So, they aim to cull about 80 individuals later this year

British geologist and naturalist William Pengelly identified the object as a badger tooth.

Long Misidentified, This Seal Tooth Pendant Was Carefully Crafted by a Prehistoric Human Roughly 15,000 Years Ago

Discovered in 1867, the artifact raises new theories about the Magdalenian people who inhabited southwest England during the Late Upper Paleolithic period

When male greater sage grouse attempt to attract a mate, they puff up their chest, droop their wings and fan their tail feathers into a starburst shape.

One of the American West’s Most Iconic Birds Is Attempting to Mate Near a Dangerous Airport. Could Robo-Birds Help Save Them?

Conservationists are deploying dancing animatronic birds to lure male greater sage grouse away from the Jackson Hole Airport, where dozens of the creatures have been struck and killed by planes

Initial excavations last month at Monticello revealed a layer of brick rubble.

Enslaved and Free Workers Built Thomas Jefferson’s Monticello Brick by Brick. Archaeologists Just Discovered One of the Kilns They Used

Researchers think the newly unearthed structure was used to fire and cure bricks during construction of the site’s original mansion in the early 1770s
