Wiring diagram of an adult male fruit fly's central nervous system

This New Brain Map Shows Every Nerve Cell in an Adult Male Fruit Fly’s Central Nervous System. Here’s Why That Matters

The recently released “connectome” joins a previously completed map of an adult female fruit fly’s brain. The digital 3D diagrams allow scientists to trace precise neural paths in the bugs’ brains, which can unlock secrets about the organ in humans

Three Wild Dogs Made a Record-Breaking Trek Across Zambia, Traveling More Than 2,500 Miles in Search of Mates

The canines achieved the longest recorded movement by any African mammal. Their journey highlights the importance of having protected corridors for wildlife

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

Tasmanian devils used to live across mainland Australia, but wild populations now inhabit only the island state of Tasmania.

Cool Finds

Tasmanian Devils Lived Alongside Humans in Northwestern Australia as Far Back as 45,000 Years Ago, Researchers Find

Fossils and marked bones unearthed in a Juukan Gorge cave suggest that the marsupial species not only once lived in the region but may have been a “garbage compactor on four legs” for its human population

Two yellow-bellied marmots ended up in the San Francisco Bay Area.

Two Chonky, Mountain-Dwelling Marmots Were Found in the Bay Area. What Were They Doing So Far Away From Their Home?

The two rodents of unusual size, rescued this month, might have hitched a ride in the engine compartment of a vehicle coming down from the mountains, wildlife officials say

Researchers estimate the T. rex was walking at a speed of roughly 3.4 to 4.5 miles per hour.

These Four Giant Dinosaur Footprints Discovered in North Dakota Might Represent the First Trackway Made by an Adult T. Rex Ever Found

A high school teacher first spotted the remarkable trail while volunteering on a paleontological dig. Researchers suspect a hulking, full-grown dinosaur marched through the then-swampy landscape roughly 66.5 million years ago

This photo of an adult male seahorse with two juveniles earned Julien Anton the overall Ocean Photographer of the Year award and first place in the wildlife category.

From seahorse farewells to saving a stranded whale, the photos capture the diversity and beauty of sea creatures—but also the perils they face

The squid emerged from the darkness at a depth of nearly two miles below the surface.

Watch an Elusive and Ethereal Bigfin Squid Float Above the Seafloor Off Central California

This marks the first time the mysterious creature has been seen alive in the northeastern Pacific Ocean. It was spotted last month by scientists on an expedition to study marine life near underwater mountains

Miracinonyx trumani that lived in modern-day Wyoming hunted mainly herbivores, such as the Saiga antelope illustrated here, according to the study.

For Decades, Scientists Thought an ‘American Cheetah’ Once Roamed North America. Turns Out the Extinct Cat Wasn’t a Cheetah

Ancient DNA from fossils found in Wyoming and Canada’s Yukon Territory suggests the wild cat more closely resembled modern pumas than modern cheetahs

Surgeons Leonardo Riella (left) and Tatsuo Kawai (right) talk to patient Tim Andrews after he received a genetically modified pig kidney in early 2025.

A Genetically Modified Pig Kidney Kept a Man Alive for a Record Nine Months, Allowing Him to Wait for a Donated Human Organ

The animal organ kept Tim Andrews off dialysis for 271 days and represents the first time a pig kidney has been used as a bridge to human organ transplantation

A nabarlek on Augustus Island, an uninhabited island in Western Australia. This is not one of the newly discovered wallabies.

Australia’s Second-Smallest Rock-Wallaby Reappears in a Region Where It Had Not Been Seen for 50 Years

The endangered nabarlek is not easy to find and difficult to distinguish from similar species. But a research team made new detections of the animals that offer “good news for their long-term survival”

Lead author Vera Weisbecker poses with a thylacine snout, alongside models of wolf, fox and crocodile upper jaws. 

The Tasmanian Tiger Was Branded a Livestock Killer. New Research Challenges That Myth

Thylacines had powerful snapping bites suited for catching small and medium-sized prey like bandicoots—not taking down large animals such as sheep and cattle, as European colonists feared

Elongated scales form leg-like structures at the tip of the spider-tailed horned viper's tail, creating a decoy arachnid that the predator can use to attract birds.

The Tip of This Snake’s Tail Looks Like a Spider. But Inside, Its Bones Are ‘Bizarrely Normal’

High-tech scans reveal the first detailed look at the internal anatomy of the spider-tailed horned viper. The findings shed light on little-known snake vertebrae and highlight the difficulty of predicting what an animal looks like from its skeleton

The statue of a human riding a leopard was found during excavations over the summer.

Cool Finds

Archaeologists Uncover a Neolithic Sculpture of a Human Riding a Leopard That’s ‘Unlike Anything We Have Encountered Before’

The artifact was found during excavations at Karahan Tepe, an 11,000-year-old site in southeastern Turkey. Created long before the invention of writing, the 2.3-foot-tall sculpture’s purpose is a mystery

Researchers spotted invasive devil firefish swimming around the wreck.

These Adorable, Critically Endangered Pygmy Raccoons in Cozumel Are Teaching One Another to Turn Trash Into Toy Balls

The observations offer rare evidence of a skill being passed among raccoons. But the work also highlights the effects of human pollution at the popular tourist destination
