MRI scanners create detailed images of the inside of the body using a powerful magnet and radio waves.

MRI Scans Might Reveal Signs of Alzheimer’s Disease Seven Years Before a Telltale Marker Appears in the Brain

Not all researchers are convinced that the brain changes detected via MRI are robust enough to become a diagnostic tool. But the findings could help researchers better understand the mechanisms that drive the neurodegenerative disease

Researchers prompted around 950 A.I. agents to search through a massive DNA database.

Anthropic Says Its A.I. Discovered a New Enzyme System That Resembles the Revolutionary Gene-Editing Tool CRISPR

Experts at the company don’t know what the newfound system does, so its potential utility in biology—if any—remains unclear. But the work marks a major advancement because the A.I. made this discovery mostly on its own

The rare two-headed turtle was found at a proteted nesting site.

Two Heads Are Better Than One: Rare, Double-Headed Turtle Hatchling Discovered on Cape Cod

The tiny diamondback terrapin was brought to a wildlife center on September 17. At the time, the creature weighed about as much as a nickel

A giant isopod plucked from the ocean near China

This Massive, Deep-Sea Roly Poly Can Go Years Without Food Thanks to a Huge Stomach and a Stolen Gene, Study Suggests

The ancestors of the giant isopod Bathynomus jamesi—a seafloor-dwelling creature that resembles a huge pill bug—acquired the snippet of DNA from bacteria more than 16 million years ago, according to a new study. The gene helps the animal slow its metabolism

Greenland's Jakobshavn Glacier

Satellite Images Reveal Greenland and Antarctica Have Lost More Than 12 Trillion Tons of Ice Over the Past 50 Years

Most of the frozen water has vanished because glaciers have been flowing faster into the ocean, rather than because of surface melting of ice sheets, according to a new study. Researchers estimate the ice loss has raised the global sea level by more than one inch

Fire amoeba wiggling around at 140 degrees Fahrenheit

Meet the ‘Fire Amoeba,’ a Newfound Blobby Organism That’s Defying Expectations About How Much Heat Complex Life Can Handle

The newly described species, found in Northern California’s Lassen Volcanic National Park, can still reproduce at 145 degrees Fahrenheit and move around at 147 degrees, according to a new study

In a First, Sea Turtles Were Spotted Nesting on the U.S. West Coast. Scientists Say the ‘Super’ El Niño Could Have Brought Them There

Two olive ridley turtles were found laying eggs on beaches in Southern California in September. In the Pacific Ocean, these reptiles normally nest farther south, often in Mexico, Nicaragua, Costa Rica and Panama

A newly identified stick insect species, Anchiale mabiensis, can be found in the Mabi Forest of Australia.

Two New Stick Insect Species Have Been Discovered in Australia—and Another One Was Hiding in Plain Sight

The new discoveries emphasize that scientists have a lot left to learn about insect diversity, even in areas with many observations

Researchers tested the battery in an RFID tag that can be rolled up in a capsule and swallowed. It can then transmit information about the digestive tract to a reader outside the body.

Scientists Invent a Digestible, Paper-Based Battery That Can Power Swallowed or Implanted Medical Devices

So far, the technology has been tested only in pigs. If it’s successful in humans, it could one day power tools that monitor your health or deliver drugs or electrical currents inside the body

The common vampire bat (Desmodus rotundus) is one of 1,500 species of bats around the world.

Where Did Bats Originate? Huge Genetic Study May Have Settled the Longstanding Debate and Rewritten the Creatures’ Evolutionary Tree

The flying mammals likely arose 65 million years ago in Europe, before spreading to Africa and then the rest of the world, according to the new research

Participants in Germany liked the Eurasian blackbird's call the most out of a list of vocalizations made by more than 100 birds.

Some Birdsongs Are More Pleasing to Human Ears Than Others. Higher-Pitched, Complex Calls Tend to Sound More Beautiful to Us

In a new study, more than 80 participants rated the pleasantness of vocalizations made by 123 European bird species. Researchers then looked at the acoustic qualities of the most—and least—liked songs

The "super" El Niño event in the Pacific Ocean has been brewing since June and will extend through February.

Scientists Say Scorching Temperatures Brought on by the ‘Super’ El Niño Could Kill Nearly Half a Million People by February

The predicted number, which includes deaths since June, likely represents an underestimate of total deaths. The heat could linger beyond February, and the climate swing could bring about other life-threatening conditions, including flooding, wildfire and infectious diseases

Members of the public are invited to vote for their favorite name for the otter: Nessie, Ruthie or Morgan. The selections are a nod to community changemakers who have made a positive impact on the river and the Bronx more broadly.

An Otter Just Returned to New York City’s Bronx River for the First Time in a Century. Now, You Can Help Name It

A trail camera photographed the animal earlier this summer, offering a hopeful sign that the once-polluted urban waterway is recovering after decades of restoration work

A new review emphasizes associations between reading engagement and benefits such as better cognitive performance.

From Boosting Mental Health to Reducing Dementia Risk, Here’s Why Reading Is Extremely Good for You, According to Science

Mounting evidence suggests that regularly cozying up with a book can increase brain and mental health, improve literacy and math skills, and even slow cognitive decline. What’s more, fiction seems to have the added benefit of introducing readers to others’ perspectives

Bubbles singled out individual bigeye trevally fish, then harassed them into puking up their most recent meal.

Meet Bubbles, a Dolphin in Australia Who Chases Fish Until They Barf—Then Eats Their Upchucked Meals

Scientists recorded 11 instances of Bubbles successfully snacking this way. They mark some of the first detailed observations of kleptoparasitism, or food stealing, in cetaceans, the group of marine mammals that includes dolphins, whales and porpoises

I’m Keeping Everyone Dry, bird behavior category winner: With its big, round eyes and cartoonish mouth, a fledgling tawny frogmouth stretches its wings and looks as though it is covering its siblings from the rain.

Experience the Wonder of Birds With These 11 Winning Photos From the Bird Photographer of the Year Contest

From a greater sage-grouse performing a mating display to a tawny frogmouth making a funny face, these photographs capture the breathtaking diversity of the world’s avian species

Using their new knowledge, the researchers became the first to successfully coax human stem cells into becoming hindbrain motor nerve cells.

Scientists Say the Human Brain Might Be Made of Two Distinct Nervous Systems That Got Squished Together

Two separate types of progenitor cells give rise to the front and back of the organ, according to a new study. The findings can help researchers study human diseases that affect the hindbrain, since its nerve cells have previously been difficult—if not impossible—to make in the lab

In one observation, a juvenile male appears to teach an infant named Fotti how to crack open a baobab fruit.

Cameras Capture Adult Chimpanzees Passing Tools—and Know-How—to Their Young, Teaching Important Skills to the Next Generation

Researchers recorded footage of wild chimps in Senegal showing youngsters how to use sticks to fish out ants and how to smash baobab fruit against rocks to open it, among other instances of instruction

Researchers looked at changes in the volume of gray matter, which is made mostly of nerve cell bodies and located in the brain's wrinkly outer layer.

The Brain Shrinks as We Age and During Major Transitions. But Surprisingly, It Seems to Take a Break From Rewiring During Menopause

Puberty, pregnancy and menopause are the three major hormonal transitions for the female brain. Researchers already knew that during the first two, the organ fine-tunes itself in response to hormonal shifts, but they haven’t been sure about the third
