Water

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

The USS Herring entered service in 1942 and completed eight war patrols.

This American Submarine Lost During WWII—Along With 83 Crew Members—Has Been Discovered in the Pacific Ocean

The honors-earning USS “Herring” sank in 1944 after taking down Japanese ships

Researchers decided not to dye or bleach the yarn so that the shipwreck’s original color could shine.

A Shipwreck, but Make It Fashion: Researchers Transformed Wooden Fragments From a 17th-Century Shipwreck Into a Pair of Stylish Maxi Dresses

Scientists at Aalto University in Finland saved pieces of the Hahtiperä wreck and turned them into textile fibers

A team is exploring shipwrecks in Lake Union, including this steel workboat submerged 30 feet deep.

An Underwater Robot Explores the Hidden ‘Shipwreck City’ Beneath the Surface of This Popular Urban Lake in the Pacific Northwest

Using a remotely operated vehicle, researchers are exploring a long-overlooked piece of Seattle’s maritime history

Mediterranean monk seals are among the rarest pinnipeds in the world.

Mediterranean Monk Seals Hide in Underwater ‘Bubble Caves’ to Avoid Tourists During the Busy Summer Season, a Study Suggests

Researchers caught the rare pinnipeds resting and sleeping in a secluded chamber on the Greek islet of Formicula. The findings suggest that these small caves should be included in efforts to protect the animals’ habitat

Tuerkayana hirtipes, a true crab species examined in the study

When Did Crabs Evolve Their Iconic Sideways Scuttle? Scientists Traced It to a Common Ancestor That Lived 200 Million Years Ago

The findings suggest that their famous lateral movement evolved just once. It may have helped the animals rapidly spread and diversify because moving in two directions meant they could easily escape predators

The researchers say this is one of the first studies looking at the effects of cold exposure over a prolonged period of time in people who are overweight or have obesity.

Regularly Wearing a Cooling Vest Might Help You Lose Body Fat, According to a New Study

Participants who were overweight or living with obesity wore the accessories for two hours every morning for six weeks and lost an average of two pounds. The researchers suspect showering or swimming in frigid water could have similar effects

Scientists used acidic and basic solutions to trigger chemical reactions in algae.

These Marine Algae Glow When Waves Disturb Them. Their Bioluminescence Could Power Electricity-Free Lamps of the Future

The single-celled organisms usually shimmer for mere milliseconds, but researchers figured out how to sustain their illumination. The technology could one day be used to light robots’ ways in the deep sea or space

A remotely operated vehicle captured this image of the ceramics from the Camarat 4.

Here’s What Underwater Robots Are Finding at France’s Deepest Shipwreck, a 16th-Century Merchant Vessel Resting at the Bottom of the Mediterranean

Known as the “Camarat 4,” the ship was loaded with cannons, cauldrons and hundreds of ceramics—which are still visible on the seafloor. Researchers are surveying the site and carefully recovering a small selection of artifacts

An example of a crannog, in the Loch of Wasdale

This Island in Scotland Is Actually a Man-Made Mini Landmass Resting on a Wooden Platform, New Discovery Shows

Scientists made significant advances in underwater archaeology techniques and photogrammetry while investigating the crannog site

The sun sets behind the hills of Duluth, Minnesota, creating a warm glow on the shimmering surface of Lake Superior.

These 15 Majestic Photographs Showcase the Beauty of the Great Lakes and Will Make You Fall in Love With the Natural Wonders

The images of Lakes Huron, Erie, Superior, Michigan and Ontario are pulled from submissions to the Smithsonian Magazine Photo Contest

After researchers aboard the Okeanos Explorer ship couldn't figure out the orb's identity, they sent it to the Smithsonian's National Museum of Natural History for a more thorough investigation.

Cool Finds

Scientists Found This Mysterious Golden Orb on the Seafloor Nearly Three Years Ago. Now, They Finally Know What It Is

After a long, winding road of tests, researchers at the Smithsonian’s National Museum of Natural History and other institutions determined that the strange blob once attached a large sea anemone to a rock

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

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
