Two livestock guardian dogs, both akbash and Great Pyrenees mixes, stand among their flock at a ranch run by the prominent dog-breeding Buchholz family.

When Coyotes Threatened Livestock on Central Texas Ranches, the Solution Was to Unlock an Ancient Ability in Dogs

Killing the predators is not nearly as effective as the intimidating presence of well-trained guardians, a role some breeds have played for 5,000 years

Once treated by humans as prey, horses became key to transportation, warfare, trade and companionship. Their history is intertwined with our own.

Gallop Into the Year of the Horse With These Five Amazing Equine Discoveries

Since their domestication, horses have changed the course of human history. It’s no wonder the Chinese zodiac associates them with prosperity and success

The Tragedy of the Alps’ Disappearing Glaciers for Those Who Live, Visit and Ski There

Warming temperatures are wreaking havoc at elevation, upending the Winter Olympics and the tourism industry and imperiling communities

Paleontologists have found early examples of theropods, the group that would eventually include tyrannosaurs. But precisely how another group of dinosaurs, known as the bird-hipped ornithischians, evolved remains a major question in paleontology.

An Asteroid Ended the Age of the Dinosaurs. But How Did Their Reign Begin? Mysterious Early Reptiles May Hold the Answer

Researchers are uncovering the evolutionary steps that set the stage for dinosaurs to rule the planet

Scientists found that fringe-lipped bats have a roughly 50 percent success rate when trying to capture prey.

These Lazy Bats Are Super-Efficient Killers That Carefully Conserve Energy to Attack at a Moment’s Notice

Wild fringe-lipped bats spend just one-tenth of the night in flight, but they can precisely snatch a calling frog and nab prey that rivals their own size

For their scale, these microbes are faster and more resilient than any human athlete.

If Microbes Entered the Olympics, These One-Celled Superstars Would Win Gold

They race, they spin, they shoot. Meet the organisms for which physical prowess is more than sport—it’s a matter of life and death

Sceptobius beetles groom ants to steal the pheromones that they produce. The beetles cloak themselves in those pheromones to match the scent of the ant colony, gaining the ability to live among the ants undetected.

These Beetles Are Entirely Dependent on Ants for Survival. Here’s Why That’s Not an Evolutionary Death Sentence

Rove beetles cloak themselves in ant pheromones to sneak into the insects’ nests for protection. But in an odd catch-22, that makes them forever reliant on their hosts

A juvenile harbor seal lies on a beach in the Netherlands.

Seals Are Seemingly Vanishing Off the Dutch Coast. These Scientists Are Trying to Get to the Bottom of the Mysterious Disappearances

Recent counts of the Wadden Sea’s adult harbor seal population have revealed a surprising trend of decline, prompting a consortium of researchers to investigate whether the animals are dying off, relocating or experiencing something else altogether

The small dinosaur Patagonykus—one of an odd-looking group called alvarezsaurs—puzzled experts with its stout claws and bird-like bones.

Small, Stubby-Armed Dinosaurs Have Confounded Paleontologists. Are Answers Finally Within Reach?

Recent discoveries about an alvarezsaur called Manipulonyx have drawn renewed attention to this group of bird-like, clawed creatures and the mysteries around their anatomy and behavior

A Brazilian keelback (Helicops infrataeniatus) cannibalizes another in 2015.

Cannibalism Among Snakes Is Far More Widespread Than Previously Thought

Scientists undertook the first comprehensive assessment of how often snakes eat their own, uncovering reports of the behavior in more than 200 species

Outbreaks of crown-of-thorns starfish have threatened the Great Barrier Reef since the 1960s.

These Hungry Starfish Are Spiraling Out of Control in Australia. Now Scientists Say They Have a New Plan to Fight Back

Synthetic pheromones may be a promising tool in attracting and culling troublesome crown-of-thorns starfish, which rapidly eat large amounts of coral on the Great Barrier Reef

Shovel-tusked elephants like Amebelodon were discovered nearly a century ago, and paleontologists have learned more about their anatomy and behavior with time. This 1932 illustration was later found to be inaccurate, as Amebelodon actually had a longer and narrower trunk.

Strange, Shovel-Tusked Elephants Puzzled Paleontologists, Until Experts Took a Closer Look at Their Teeth

The animals’ extended lower jaws were seemingly made for scooping, but research over the past few decades has found they could do a lot more than initially expected

A gentoo penguin peers up from its colony’s nesting grounds on Booth Island, in the Antarctic Peninsula. The species, an adaptable forager that can switch prey when krill are scarce, has expanded into parts of the Antarctic Peninsula that were once too icy to inhabit.

The Penguins That Thrive—and the Ones Left Behind—as Antarctica Warms

A new decade-long study tracked 37 penguin colonies and found that the birds are breeding earlier. The shift marks one way among many that climate change is transforming life at the bottom of the world

Icicles form on a fence and reflect the blue sky after an ice storm.

Through gene-editing, researchers in the field of synthetic biology hope to make endangered species more resilient against disease or climate change and protect human health, among other goals.

Three Stunning Ways Biologists Aim to Edit Animal and Plant Genes to Fight Diseases and Extinction

The strategy, known as synthetic biology, is gaining momentum globally as a conservation tool and human health solution, despite attracting some critics

In “Depicting Dark Waters,” British sculptural model maker Alice Baker collaborated with marine biologists from the Netherlands and Sweden to depict European cold-water corals in glass and raise awareness about deep-sea ecosystems.

Art Meets Science

The Hidden World of Cold-Water Corals Rises to the Surface With These Glass Sculptures That Are Resurrecting a Lost Craft

As increased industrial activity puts fragile deep-sea ecosystems at risk, one artist is raising awareness about imperiled corals through scientific model making

Naked mole-rats are unusual for their long lives and resistance to cancer. Now, researchers suggest the rodents not only tolerate but prefer to be in low-oxygen air.

Naked Mole-Rats Prefer Low-Oxygen Air That Would Kill Most Mammals, Adding to Their List of Death-Defying Superpowers

These underground rodents are the first mammals found to actively choose air with lower-than-normal oxygen levels. Their remarkable ability to survive these conditions could offer a key model for researchers studying new treatments for stroke or lung diseases in humans

The Swiss Alpine Club (SAC) owns about half of Switzerland’s 320 huts, including the Almageller Hut on the southern side of Weissmies Mountain above the village of Saas-Almagell.

The Race Is On to Save the Alps’ Famous Huts and Trails as Melting Permafrost Threatens to Destroy Them

Hiking will always be a part of life in the Alps, but climate change has made navigating high-alpine routes more complicated

Research suggests that elephants use certain plants for medicinal purposes.

When Some Elephants Raid Farms, They Might Not Be After a Snack. They Could Be Looking for Medicinal Plants

A recent study suggests that the large mammals may seek out parts of bananas and papayas when they’re suffering from gut parasites, sparking a cross-species exchange of pharmaceutical knowledge

Black soldier fly larvae grow in a high-tech facility at Innovafeed in Nesle, France. The company, which also has a facility in Decatur, Illinois, is the world’s largest producer of black soldier fly larvae.

Maggots Are an Incredibly Efficient Source of Protein, Which May Make Them the Next Superfood for Humans

Inexpensive to raise and insatiably hungry for trash, black soldier fly larvae are already on the menu for livestock, pets and, maybe soon, people
