A human embryo embeds itself into a fake uterus created by researchers.

See the First 3D Images of a Human Embryo Implanting, Shedding Light on the Crucial but Little-Known Process

A new study shows how human embryos reshape their environment by pulling on uterine tissue

Weaver ants link their bodies together to form chains while bending leaves to create their elaborate dwellings.

Weaver Ants Use Teamwork to Become ‘Superefficient,’ Building Complex Nests From Leaves With Extra Pulling Power

When humans work in large teams, they become less individually effective. But each ant grows more efficient when collaborating—a discovery that could help engineers build better robots

Researchers dissected nearly 500 post-mortem birds from five Australian species, including the rainbow lorikeet (species pictured above).

Sex Reversal Is More Common in Birds Than Previously Thought, Suggests Study of Australian Species

Researchers find that about 5 percent of birds studied have a mismatch between genetic and physical sex—including one male bird that seems to have laid an egg

Demonstrators in Berlin last year advocated for increased awareness of ME/CFS.

Scientists Find Links to Chronic Fatigue Syndrome in Genes and in the Gut Microbiome

Two studies present new data on ME/CFS, offering “credibility and validity” to the experiences of patients struggling with symptoms

Golden apple snails and humans have similar eyes with related structures. Understanding how the snails can regrow them could help scientists heal human eyes.

This Snail Can Regrow Its Eyes—and Understanding How May One Day Help Humans With Injuries

Researchers pinpointed a gene related to eye development in golden apple snails, which can regenerate amputated eyes within about a month

An illustration of E. coli. Scientists have been racing to shrink the genetic code of this bacterium.

Scientists Rewrite the Genetic Code of E. Coli, and It’s Drastically Different From Anything Found in Nature

The synthetic bacteria contain a shorter genetic code with 57 codons rather than 64, freeing up space for further edits that might lead to new drugs or virus-resistant microbes

Two adult female mountain gorillas rest with one of their infants.

Female Gorillas Form Ties That Bind, Helping Them Join New Social Groups

A new study finds that when female mountain gorillas move to a new crowd, they look for females they’ve already met

Sea star wasting disease, seen here, makes starfish melt into goo or sludge.

Researchers Discover the Culprit Behind a Gruesome Disease That Makes Sea Stars Lose Their Limbs and Melt

A new study points a finger at a strain of the bacterium Vibrio pectenicida, which belongs to the same genus as Vibrio cholerae, known for causing cholera in humans

The new species lives in the tropical and subtropical waters of the Atlantic, from the eastern United States down to Brazil.

Scientists Identify a New Manta Ray Species, Just the Third Known in the World

Meet Mobula yarae, a large marine creature that lives along the coast in the Atlantic Ocean

Winter-run Chinook salmon are unique because they spawn in the summer, then migrate as adults to the Pacific Ocean in the winter.

For the First Time in Nearly a Century, Adult Winter-Run Chinook Salmon Are Swimming in California’s McCloud River

Video footage shows a female guarding her nest while several smaller males compete for positioning nearby

The whole Pulaosaurus qinglong skeleton

Cool Finds

Rare Fossil Suggests Some Dinosaurs May Have Sounded Like Birds and Shared Similar Vocal Anatomy

Pulaosaurus qinglong is only the second non-avian dinosaur to be discovered with a preserved bony voice box

New light microscopy techniques can distinguish objects down to less than ten nanometers. 

These Super-Resolution Microscopes Are Revealing the Inner Lives of Cells

Advanced light microscopy techniques are giving scientists a new understanding of human biology and what goes wrong in diseases

New research suggests a large crocodile-like creature attacked a "terror bird" 12 million years ago.

Even Apex Predators Like ‘Terror Birds’ Had Enemies, Research Suggests

Bite marks on a fossilized leg bone found in South America suggest a crocodile-like creature attacked a massive, meat-eating bird 12 million years ago

For the experiments, the scientists worked with plain-body octopuses (Callistoctopus aspilosomatis).

Octopuses Fall for the Rubber Hand Illusion, Just Like Humans, Pointing to a Sense of Body Ownership

The trick that plays with awareness of one’s own limb appeared to fool all six of the cephalopods tested in a series of experiments

A scan of a Rosenberg's goanna (Varanus rosenbergi) reveals chain mail-like osteoderms and the endoskeleton in the left half of the image.

These Odd Bony Structures Were Hiding Beneath the Skin of Far More Lizards Than Thought, Researchers Find

Called osteoderms, the chain mail-like plates may have helped some species adapt to Australia’s harsh environment

The remotely controlled robotic rabbits have been placed at various undisclosed locations in South Florida to see how well they fool the invasive snakes.

‘Robo-Bunnies’ Are the Newest Weapon in the Fight Against Invasive Burmese Pythons in Florida

Scientists are experimenting with robotic rabbits in hopes of luring the destructive snakes out of hiding so they can be euthanized

Breakthroughs in tagging technology are opening a window into the lives of smelt and other small swimmers—a shift some scientists say could transform our understanding of the underwater world’s more minute creatures.

A New Generation of Tiny Tracking Tags Offers a Fresh Look at the Lives of Little Fish

Researchers at the Department of Energy’s Pacific Northwest National Laboratory have developed a tag the size of a grain of rice that can also work underwater

Researchers discover the secret behind Burmese pythons' ability to fully digest the bones of their prey.

Researchers Discover the Trick That Allows Burmese Pythons to Digest the Bones of Their Prey

Special intestinal cells collect excess minerals into particles the snakes can poop out, according to a new study

A western gull like this one surprised researchers by riding on an 18-wheeler to an outdoor composting facility in California.

A California Gull Hitched a Ride on a Garbage Truck and Took an 80-Mile Journey to a Compost Facility. Then It Happened Again

GPS tracking data showed the bird zooming across bridges and interstates at 60 miles per hour on two occasions in 2018

For the first time ever, the genome of a knotty sea spider was sequenced in high resolution.

These ‘Weird’ Sea Spiders Don’t Have Abdomens—and Instead Store Organs in Their Legs. With DNA, Scientists Are Learning Why

Researchers sequenced the knotty sea spider’s genome for the first time, revealing a missing gene that many other animals have
