Bridges, mountains, caves and rock formations that seem impossible to explain become magnets for folklore

In the lab, archaeologists showed how they could rapidly produce thick rope by threading cattail fibers through a replica of a Stone Age tool.

Archaeologists Are Reconstructing the ‘Invisible’ Technologies of the Stone Age, From Rope to Thread and Twine

Largely missing from the archaeological record, fiber innovations played a huge role in the lives of early humans. Researchers are weaving together new insights from the traces they left behind

Smoke from massive wildfires in Canada engulfed the New York City skyline, reducing visibility and casting an orange haze over city on July 16, 2026.

From 22,000 Miles Up, This Satellite Tracks Airborne Health Threats Almost in Real Time

The new instrument, called TEMPO, captures hourly snapshots of the pollutants swirling in the daytime atmosphere over North America—“chemical weather” reports that are helpful to public health researchers and government officials

The Earth in the Mesozoic Era, when dinosaurs roamed the planet, looked much unlike how it does today—even beyond presence of creatures like Giganotosaurus.

Five Ways the World of the Dinosaurs Looked Different From Ours, Beyond the Presence of the ‘Terrible Lizards’

Earth has changed dramatically since the Age of Dinosaurs, from its climate to geography and animal life

Lake sturgeon—massive and long-living fish in the Great Lakes—may survive to much older ages than scientists previously thought, according to a recent study. Here, a juvenile lake sturgeon is captured during a fisheries assessment in the St. Clair-Detroit River System.

Some Fish in the Great Lakes Might Be More Than 400 Years Old, a Study Suggests, Outliving Around 15 Generations of Humans

Lake sturgeon may be among the longest-living vertebrates, second only to Greenland sharks, according to recent research. However, scientists note that follow-up work is necessary to clarify the species’ life span

The white-headed duck is “one of the true eccentrics of the waterfowl world because almost everything about it seems unusual,” says waterfowl expert Nicky Petkov.

Spain’s White-Headed Ducks Have a Signature Color Right in the Name. And That Isn’t Even Their Most Remarkable Hue

The first thing you’re likely to notice is the blue bill. But beyond appearances, the duck has an exciting story to tell about conservation and recovery

In loud conditions, a tokay gecko adjusts its call, which is typically used to find a mate or defend territory.

Reptiles Make a Surprising Amount of Noise. Here’s What Those Sounds Might Mean, From Pops to Hoots to Bellows

Scientists are realizing that turtles, lizards and crocodilians communicate vocally more than they once thought

Meet the team that closely monitors the playful canines, which need help to form diverse packs and stop their numbers from dwindling

A harbor porpoise surfaces near the Golden Gate Bridge.

Marine Biologists Solved a Wildlife Mystery From the Walkway of the Golden Gate Bridge: How the Harbor Porpoise Mates

The dolphin-like marine mammals returned to San Francisco Bay in 2008 after a decades-long absence from the area. Scientists took the rare opportunity to closely observe their behavior, and what they uncovered might help at-risk porpoise populations

The mushroom Psilocybe pelliculosa is one of several species that produce psilocybin, a natural compound with hallucinogenic properties.

Could Psilocybin Help Treat Anorexia? A Small Clinical Trial Suggests the Psychedelic May Make Patients More Open to Recovery

The drug, paired with intensive psychological support, may loosen the rigid patterns of thought associated with the eating disorder, scientists say—but they caution that it is not a magic cure

The crew of the Artemis 2 mission captured this image of a total solar eclipse just after rounding the far side of the moon on April 6.

‘Like a Hole in the Universe’: Artemis 2 Astronaut Victor Glover Reflects on Seeing a Total Solar Eclipse While Flying by the Moon

The four astronauts who rounded Earth’s natural satellite in April got an extremely rare view of the dark lunar disk blocking out the sun. Researchers say the observations provide unique scientific value for understanding our star’s mysteries

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

A digital illustration of typical prokaryotes—cells that do not contain a nucleus. Bacteria and archaea are the two kinds of prokaryotes on Earth, and their ancestors were the first organisms to evolve.

A New Study Points to Two Origins of Life on Earth by Tracing Early Chemical Reactions in Single-Celled Organisms

The work challenges the assumption that all life descended from one free-living cell. Instead, it suggests that two microbial lineages, the bacteria and archaea, evolved independently from a primordial, nonliving ancestor
