A 187-foot-tall dipterocarp tree

Tall Trees Were Thought to Be More Vulnerable to Drought. But These Towering Plants in Southeast Asia Have Adapted to Move Water Efficiently

A new study found that enormous dipterocarp trees have special adaptations to transport water up to their highest limbs, challenging the assumption that they would more easily succumb to dry conditions

Researchers came up with the new count by studying insect biodiversity in a conservation area in Costa Rica.

Earth Might Be Home to 20 Million Insect Species—More Than Three Times as Many as Previously Thought, a Study Suggests

Recent estimates have come to the consensus that our planet hosts roughly six million species. But new research reveals that those counts may be drastically underestimated

The "cold blob," shown in blue near the top, is also called the Atlantic "warming hole."

As the Ocean Warms, a ‘Cold Blob’ in the Atlantic Has Puzzled Scientists. It Might Be a Warning Sign About a Key Current System

A patch of water south of Greenland and Iceland has cooled by nearly 1.8 degrees Fahrenheit since 1900. A new study suggests that it shows a crucial system of ocean currents is weakening, which could alter Earth’s climate

The new species is covered in spots and dashes.

Scientists Discover a New Species of ‘Walking’ Shark in Papua New Guinea. They Suspect It’s at Risk of Going Extinct

The creature belongs to a unique group of sharks whose members can use their strong pectoral fins like legs to get around

A city-dwelling male bowerbird near the structure that it built to woo mates, called a bower.

Male Bowerbirds in Australian Cities Are Turning Human Trash Into Treasure to Impress Potential Mates

Even rural birds prefer human-made objects, such as colored glass and wire, when given the choice between them and natural decorations, like leaves and shells, according to a new study

Ants are pictured at the Metropolitan Natural Park, a protected area in Panama City, on January 26, 2025.

Ants Can Get Distracted by Cookies, Chips and Other Junk Food. Here’s Why That Could Be a Problem for the Environment

The insects enjoy snack crumbs, but new research shows that this unnatural food source can divert them from one of their most significant roles: dispersing plant seeds

Venus flytraps and other carnivorous plants have long intrigued scientists, including English naturalist Charles Darwin.

Venus Flytraps Snap Their Traps Shut in Less Than a Second. Scientists Say They’ve Discovered How the Predatory Plants Are So Fast

The walls of cells in the leaves’ outer layer suddenly soften, allowing the structures to hinge into a closed position, according to a new study

Scientists explored a tiny portion of the site during more than 30 dives with a submersible.

Scientists Discover the World’s Largest, Deepest Whale Graveyard, Where Cetacean Remains Have Been Piling Up for Five Million Years

The massive necropolis, located deep in the southeastern Indian Ocean, is teeming with marine life supported by the whale carcasses, including many suspected new species

The blue-fronted lorikeet was first described based on seven specimens collected in the 1920s.

Cool Finds

This Colorful Parrot Had Been Seen Only Once Over the Past Century. Birders Just Rediscovered It in an Unexplored Indonesian Forest

First described in the 1920s from seven specimens, the blue-fronted lorikeet hadn’t been spotted since 2014. Bird-watchers on a recent trek snapped photos of the rare bird and captured the first known audio recordings of its calls

A swan swims on the Scharmützelsee at sunrise on July 2, 2025, when temperatures in the nearby German cities of Berlin and Brandenberg were expected to hit 102 degrees Fahrenheit.

‘Stupid Hot’: Heat Waves Muddle the Minds of Animals and Humans as Confusion and Aggression Seem to Rise With the Temperature

Wide-ranging research suggests that as temperatures increase, some creatures pick fights while others struggle to learn. The findings hint at consequences that may ripple through ecosystems

Queen bee larvae develop in unique peanut-shaped cells.

What Determines Royalty Among Honeybees? Not Just a Distinct Diet—Queens Also Need Specially Built Regal Chambers, a Study Suggests

The peanut-shaped compartments where future queens grow up seem to play an important role in development. The wax has chemical and physical differences from that in other parts of the hive

By combining ecological data-gathering with philosophical contemplation, Leopold bridged the art and science of conservation.

America at 250: The Revolutionary Spark

In the Early 1900s, a Young Ecologist Shot a Wolf and Watched the Life Leave Its Eyes. That Changed His Position on Conservation

Aldo Leopold’s writing reconsidered the place of humans in the natural world and challenged people to be less conquerors of the land and more citizens of it

A female blue crab with an acoustic telemetry tag on its shell. Scientists at the Smithsonian Environmental Research Center use telemetry tags to track the migration of blue crabs throughout the Chesapeake.

Young Blue Crabs Have Been Mysteriously Dwindling in the Chesapeake Bay for Years. This Winter, They Saw a Boost in Numbers. What’s Driving These Trends?

A recent report detailed a 50 percent drop in juvenile Chesapeake blue crabs since 2010. Then, a survey found a surprising surge in the young crustaceans this year

In February 2020, naturalist guides Lizardo Proaño and Juan Carlos Narváez photographed a harvestman eating a live frog during a night hike at Mashpi Lodge in Ecuador.

Daddy Longlegs Seem to Hunt Frogs in South America, Revealing the Gangly Arachnids as Overlooked Predators

A new study suggests that harvestmen actively attack the slippery amphibians, rather than just scavenging them. The findings hint that the spineless creatures have a more complex relationship with vertebrates than previously thought

Human development—such as roads—affects wildlife. But so does the presence of people.

The Mere Presence of Humans—Not Just Our Changes to the Land—Can Alter Wild Animals’ Behaviors, a New Study Suggests

Researchers examined GPS tracking data from thousands of animals representing 37 species and anonymized cellphone location data from 2020, a year of Covid-19 lockdowns, and the previous year

Gentoo penguins have been considered a rare beneficiary of climate change due to their population growth on the Antarctic Peninsula. Splitting the birds into four species brings to light regional threats and declines.

Gentoo Penguins Are Actually Four Different Species, Scientists Say, Revealing They’re Not Quite ‘Winners’ of Climate Change After All

A new study indicates that the adaptable birds evolved into distinct lineages as isolated populations shifted to match their environmental conditions over time. The work has implications for how conservationists assess threats to gentoos

A chick hatches around 18 days after embryo transfer to the artificial egg, according to the company.

‘De-Extinction’ Company Says It Hatched Chicks From Artificial Eggs, Paving the Way for Resurrecting Dodos and Other Bygone Birds

Colossal Biosciences announced that 26 live baby chickens have emerged from 3D-printed honeycomb structures. But the company does not plan to detail the system in a paper, and its mission has faced criticism

Sweetgrass basket weaving is one of the most enduring cultural traditions of the Gullah Geechee people, descendants of Africans enslaved on the rice, indigo and cotton plantations of the southeastern United States.
