Animals

Common big-eared bats eat relatively large insects, such as katydids.

A Robot Is Unraveling the Secrets of How Some Bats Bounce Sound Waves Off Leaves to Find Insect Prey

A new study from the Smithsonian Tropical Research Institute used a robot to mimic common big-eared bats’ echolocation skills

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

Veronika scratches her back. 

A Cow Named Veronika Can Scratch Her Back With a Broom. Watch the Video That Scientists Are Calling the First Documented Evidence of Cattle Using Tools

The pet cow’s tool use challenges long-held assumptions about bovine intelligence

A reconstruction of what Manipulonyx reshetovi may have looked like

This Dinosaur May Have Used Its Strange Clawed Hands to Pilfer and Pierce Eggs

A fresh analysis of a fossil found almost 50 years ago reveals a newly described genus named for its “manipulating claw”

New Research

These Baffling Bone Artifacts Discovered by an Amateur Archaeologist May Be the World’s Oldest Whale Harpoons

After revisiting items from a Brazilian museum, researchers think humans may have been hunting whales 5,000 years ago, a millennium earlier than previously thought

The "Tumat puppies" were discovered with their fur, skin and stomach contents still intact.

Contents of a Wolf Pup’s Stomach From 14,400 Years Ago Are Teaching Researchers About the Lives of the Last Woolly Rhinos

Analysis of woolly rhinoceros DNA recovered from the permafrost-preserved wolf further hints that the Ice Age beasts went extinct because of a sudden shift in the climate

A worker bee (left) and a queen bee (right) slurp up artificial nectar during laboratory experiments.

Queen Bumblebees’ Tongues Aren’t Built for Slurping Nectar—Which Might Keep the Royals Homebound

Queen bumblebees have sparser hair on their tongues than worker bees, which makes them less efficient at lapping up nectar, new research suggests

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

Same-sex behaviors seem to be common among rhesus macaques.

Biologists Reveal How Same-Sex Sexual Behavior May Have Given Some Primates an Evolutionary Advantage

Nonhuman primates like bonobos and chimpanzees might engage in same-sex sexual activities to strengthen bonds, particularly in harsh environments or within strict social structures, a new study suggests

Inky paw prints on a 15th-century Flemish manuscript

A Cat Left Paw Prints on the Pages of This Medieval Manuscript When the Ink Was Drying 500 Years Ago

An exhibition called “Paws on Parchment” tracks how cats were depicted in the Middle Ages through texts and artworks from around the world—including one example of a 15th-century “keyboard cat”

The study involved pups like Miso, a 6-year-old male border collie from Canada who knows the names of about 200 toys.

New Research

Some Dogs Are ‘Gifted Word Learners’ That Learn Language by Eavesdropping—Just Like Human Toddlers

New research suggests prodigious pups that already have large vocabularies can learn new words by listening in on their owners’ conversations

The larvae feed on the leaves of elm trees in a distinctive zigzag pattern.

This Invasive Wasp Is Wreaking Havoc on Elms in North America—and the Damage May Soon Spread to Other Trees

Elm zigzag sawflies can munch on plants beyond their preferred elm trees when foliage isn’t available, a new study suggests

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

Some octopuses have incredible camouflaging abilities. 

Inspired by Octopus Skin, This Synthetic Material Can Change Color and Texture on Demand

The animals’ camouflaging capabilities have long inspired humans. The new material could one day help researchers improve robotics or electronic screens

Strange fossils reveal that predatory fish with a wide array of dental setups once stalked prehistoric waters.

Sharklike Fish With Weird, Buzz-Saw Jaws Sliced Through the Seas, Then Vanished. Now, Paleontologists Are Unraveling Their Secrets

These “total monsters of fishes” are extinct today, though new clues about their lives come from CT scans and their closest living relatives: the big-eyed ratfish of the deep sea

Five quartz arrowheads unearthed in South Africa contained traces of toxins.

Cool Finds

Archaeologists Just Discovered the Oldest Known Evidence of Poison Arrows, Which Hunters Used to Slow Down Their Prey 60,000 Years Ago

New research reveals traces of plant toxins on arrow tips in South Africa, suggesting that the technique was used tens of thousands of years earlier than scientists thought

The introduced population of ostriches consists of five individuals, which conservationists hope will reproduce and flourish at the reserve.

Rare Red-Necked Ostriches Introduced in Saudi Arabia to Replace Birds That Went Extinct More Than 80 Years Ago

The released birds are the closest living relatives of the extinct Arabian ostrich. The flightless animals’ return is part of a broader “rewilding” effort at a huge nature reserve

Brainless upside-down jellyfish, like this one in its natural habitat near Eilat, Israel, spend about one-third of their time asleep.

Even Though They Don’t Have Brains to Rest, Jellyfish and Sea Anemones Sleep Like Humans

Sleep may have evolved to help reduce DNA damage in nerve cells long before they became centralized in the brain, a study suggests

Whooping Cranes Came Back From the Brink of Extinction. Now, New Threats Are Converging on Their Texas Wintering Grounds

Some residents along the Gulf Coast are creating habitat for the endangered birds on their properties, but development, saltwater intrusion and bird flu are putting pressure on the species’ recovery
