The Bering Strait is a narrow waterway between Russia and Alaska that connects the Pacific and Arctic oceans.

Could Building a Dam Across the Bering Strait Save the Planet From Some Effects of Climate Change?

A preliminary study suggests that blocking off the waterway between Russia and Alaska could help the survival of a key system of ocean currents. But there could be potential unforeseen consequences, particularly to marine ecosystems

Laboratory experiments involving pregnant mothers suggest that they can spread yawns to their soon-to-be-born offspring in the womb.

Fetuses Can ‘Catch’ Yawns From Their Mothers While Still in the Womb, New Research Suggests

Yawning is considered a social behavior. Although fetuses were known to yawn, scientists weren’t sure if it was a self-contained reflex or if they could somehow detect cues from their moms

Neanderthals and modern humans have differently shaped skulls, which scientists have long assumed meant they also had different brains. But new research challenges that assumption.

Did Homo Sapiens Really Outsmart Neanderthals? Different Skull Shapes Didn’t Necessarily Mean Unequal Brain Capacity, New Research Shows

A study from U.S. and Chinese researchers suggests Neanderthals and early modern humans probably had similar cognitive abilities

The Relaxation of Regularly Listening to Songs or Drawing Pictures May Actually Slow Cellular Aging, New Research Shows

According to a new study, people who are exposed to art on a weekly basis are about a year younger “biologically” than those exposed only once or twice per year

This Microscopic Fungus Survived NASA’s Sterilization Protocols—and Is Potentially Hardy Enough to Contaminate Mars

The microbe was gathered from the agency’s clean rooms, where experts build spacecraft in carefully controlled environments. The findings reveal gaps in the agency’s procedures to prevent durable hitchhikers

One-celled algae called diatoms are unique because their cell walls are made of transparent silica, like glass, allowing their internal patterns to be visible. Diatoms are key producers of atmospheric oxygen and uphold the aquatic food chain.

The sixth annual competition showcases scientific microscopic imaging, illuminating tiny parts of nature, from individual cells to arthropods, diatoms and a zebrafish brain

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

To estimate the wolf population, researchers observed animals from planes, followed tracks on the ground and inspected kill sites this year.

Wolves Are Thriving at Michigan’s Isle Royale National Park, Reaching Their Highest Numbers in Almost 50 Years, New Data Suggests

Scientists estimate that 37 of the animals now roam the rugged archipelago, which has contributed to the dwindling moose population. But the predator-prey ratio might be stabilizing

Indigenous communities in the Andes domesticated the potato between 6,000 and 10,000 years ago.

Potatoes Didn’t Just Feed Ancient Indigenous Communities in the Andes—the Tasty Tubers Also Reshaped People’s DNA

A new study finds that Indigenous Andeans living in what is now Peru have extra copies of a gene called AMY1, which helps the body digest starch

NASA Just Uploaded More Than 12,000 Stunning Photos From the Artemis 2 Mission. Here Are a Few of Our Favorites

Although the mission’s four astronauts sent a few photos to Earth while in space, most needed to be delivered via physical memory cards once they returned to the planet

Microplastics are particles smaller than five millimeters in length, or narrower than a pencil-tip eraser. 

Microplastics Are Swirling Around in the Atmosphere, Where They Might Be Contributing to Climate Change

Airborne plastic particles, particularly colorful ones, absorb more sunlight than they reflect, which can heat the surrounding air, according to a new study

These Singing Mice Squeak Back and Forth—and Don’t Interrupt. Scientists Found the Brain Pathway Behind Their Impressive Songs

Alston’s singing mice carry out complex vocalizations and even appear to converse politely with one another. The neural circuitry that makes this possible is simpler than researchers expected

Australia's Twelve Apostles were pushed out of the water by tectonic plate movement. 

It Took Millions of Years for Australia’s Famous Twelve Apostles Landmark to Rise Out of the Sea

The iconic tourist destination provides a beautiful view, but also represents a physical record of Earth’s climate history

Two Alpine ibexes butt heads, slamming their horns together in a powerful battle that can be heard from far away. They wandered up the slope together afterward.

From a lunging frog to the majestic movements of penguins, the honored photographs capture the wonder of wildlife and beauty of natural landscapes

Curiosity had a 28.6-pound rock dubbed "Atacama" stuck to its arm for a while.

NASA’s Curiosity Rover Had a Martian Rock Stuck on Its Arm for Days. Watch It Finally Shake the Stubborn Stone Off

While drilling has fractured rocks, this is the first time the instrument has ever accidentally pulled a whole chunk from the ground, according to the space agency

Kenya's Great Rift Valley

East Africa Might Break Off From the Continent Sooner Than Scientists Thought—and a New Ocean May Fill the Gap

A new study suggests that a rift in Kenya and Ethiopia has reached a critical stage in the split-up process, and that water may flood it in a few million years

The Fall of the Roman Empire Was Less a Clash of Civilizations and More an Opportunity to Mix and Mingle, a New Genetics Study Shows

Researchers who analyzed genomes from early medieval graves in modern-day Germany hypothesize that people from the former Roman Empire formed families with Germanic people soon after the empire fell

Researchers studied social learning in the birds by introducing a novel food item: colorfully dyed almonds.

Wild Cockatoos Learn Which Snacks Are Safe to Eat by Copying Their Friends, New Research Suggests

Munching on the wrong items can lead to illness, but social learning might help the birds avoid making a potentially deadly mistake. The phenomenon could help explain why certain cockatoos have fared so well in urban environments

This Tiny Celestial Body Past Pluto Shouldn’t Have an Atmosphere—but Astronomers Say They May Have Detected One

Worlds this small and distant are thought to be too cold and have too little surface gravity to hold onto gases. But the findings suggest that icy, rocky objects in the solar system’s outer reaches are more dynamic than we thought
