Water

Williston Lake is the seventh-largest reservoir by volume in the world. 

A Lake in Canada Got a Mysterious New Island. Then, It Disappeared—and Now It’s Back

The floating forest appeared in a well-mapped reservoir in British Columbia. Its presence and vanishing act have puzzled locals and officials at the power utility that operates the lake, but other similar islands exist elsewhere

America's 250th Anniversary

To Defeat the Royal Navy During the American Revolution, a Rebel Inventor Designed a Secret Weapon: a Bomb-Carrying Submarine

David Bushnell developed the “Turtle” submersible as a student at Yale University. The vessel’s attack on a British flagship failed, but the trailblazing boat’s legacy endures 250 years later

Researchers have spent the past two years studying the interactions between common octopuses and blue crabs and perfecting breeding techniques.

Blue Crabs Have Taken Over the Adriatic Sea. To Fight Them Off, Italian Researchers Just Released Thousands of Baby Octopuses

Although prized in the United States, the crustaceans have been decimating ecosystems and the fishing industry in Italy. Experts hope that an army of natural predators—common octopuses—can help contain the invasive species’ spread

A new museum focused on the world of whales will open next year in Norway.

A New Museum in Norway Is Bringing Visitors Into the World of Whales—From Life-Size Orcas to Immersive Underwater Exhibits

Opening in 2027, The Whale will explore the science, behavior, evolution and cultural history of whales through art, storytelling, sound and architecture

A hunger stone along the banks of the Elbe River in Decin, a city in the Czech Republic

‘Hunger Stones’ Resurface in Europe, Bringing Centuries-Old Warnings Back Into View as Rivers Hit Historic Lows

As drought exposes stretches of riverbed in central Europe, markers carved by past generations to record low water levels are emerging once again

A swarm of Chaoborus edulis flies over Lake Malawi

Why Don’t Insects Live in the Ocean? Scientists Just Ruled Out One Possible Explanation Thanks to Deep-Diving Fly Larvae

Researchers thought that insects might not live there because their respiratory systems would implode from water pressure. But certain fly larvae in East Africa make daily trips toward the bottom of Lake Malawi with the help of strong air sacs that contain a stretchy protein

With Eco Purge, Arya Satheesh won the European category of the 2026 Earth Prize, the largest environmental competition in the world for young students. She was awarded $12,500 to continue to develop her prototype.

This High Schooler Invented a Plant-Based Plastic That Removes Microplastics From the Environment as It Biodegrades

Eighteen-year-old Arya Satheesh created her award-winning Eco Purge to help address the global problem of plastic pollution

“This wreck is an absolute, untouched monument to 19th-century diplomacy and elite international relations in Europe,” says diver and researcher Pawel Truszynski.

Cool Finds

This Ship Sank in the Baltic Sea With Presents Bound for a Romanov Czar. Its Cargo Included Champagne, Luxury Mineral Water and Rare Meteorites

New research suggests that a shipwreck discovered off the coast of Sweden in 2024 may have been transporting gifts from the German Duchy of Nassau to Alexander II of Russia in the immediate aftermath of the Crimean War

A mother floating belly-up next to her calf

Why Are These Whales Floating Upside-Down? They Might Just Be Moms Who Need a Break From Feeding Their Babies

Each year, southern right whales migrate thousands of miles from their feeding grounds to breed, give birth and raise their young. Taking rests and regulating their calves’ nursing schedules might help mothers conserve energy while they’re far from food

Ammonites swam in the Western Interior Seaway that once covered a large portion of North America. These iridescent fossils from South Dakota, around 69–72 million years old, preserve inner shell layers made of aragonite, the same mineral that gives pearls their luster.

An Ancient Sea Once Split North America Down the Middle. The Beautiful Multicolored Ammonite Shells From Its Waters Are So Perfectly Preserved That They Still Shimmer Today

Spectacular marine fossils tell the story of the long-gone Western Interior Seaway and the planet’s past aquatic life

Dead and dying sea creatures have been washing ashore on beaches in South Australia over the past 15 months because of a toxic algal bloom.

The Culprit Behind South Australia’s Deadly Algal Bloom Might Be the Most Toxic Species Ever Tested, Scientists Say

Karenia cristata, a rare type of microscopic algae that produces toxins that harm nerve cells, can be lethal at very low concentrations

Scientists analyzed about 25 years' worth of data from the Fram Strait, a passageway where the Arctic and Atlantic oceans meet.

The Arctic Ocean May Have Passed a Crucial Tipping Point That Could Harm Food Webs and Worsen Climate Change

Sea ice loss seems to have triggered a decline in the nutrient nitrate, affecting the tiny organisms that form the foundations of marine food chains and absorb atmospheric carbon dioxide, according to a new study

Scientists think sperm whales entered the Mediterranean Sea via the Strait of Gibraltar roughly 20,000 years ago, then began to spread east.

Sperm Whales Living in the Eastern Mediterranean Sea Seem to Have Developed a Distinct Dialect From Those in the West

All Mediterranean sperm whales were thought to be part of one cultural group, identifiable by a unique pattern of clicks, or a coda. But sound recordings suggest that eastern creatures use a sped-up version of the western whales’ coda

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

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

Indo-Pacific bottlenose dolphins live in the tropical waters of the Indian and western Pacific oceans.

Female Dolphins Seem to Remember Which Males Were Aggressive During Mating Season—and May Try to Avoid Them

When researchers played underwater recordings of pushy males, females that were capable of becoming pregnant swam away from the sounds

The Rumkale fortress ruins sit on the banks of the Euphrates River in Turkey.

Scientists May Have Discovered the Origins of the Euphrates River, Which Helped Nurture Some of the Earliest Known Civilizations

The famous waterway began as two rivers, a new study suggests. Tectonic activity around five million years ago probably made them change course and merge, helping to birth the Fertile Crescent

Goblin sharks have elongated snouts and extendable jaws, which they use to snatch prey.

‘Ugliest Shark on the Planet’: See the Elusive Goblin Shark, Filmed for the First Time in Its Deep-Sea Habitat

Scientists spotted the enigmatic creatures in 2019 and again in 2024, marking the first times they’ve been observed alive in the wild. The sightings drastically expand the animals’ known geographic and depth range

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

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
