Remoras might dive into manta rays' rear ends when they're scared.

This Fish Hitches Rides in Manta Rays’ ‘Buttholes,’ According to New Research

Scientists suspect that the behavior could harm the manta rays, suggesting a complex relationship between remoras and their hosts that can sometimes be parasitic

Laboratory experiments involving pregnant mothers suggests 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. While 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

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

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

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

Timmy the Whale Was Released Into the North Sea After Being Stranded Off the German Coast for Weeks. Was That the Right Call?

The humpback whale first entered shallow water at the end of March, but its health deteriorated over the past few weeks. Experts have criticized efforts to rescue the animal, which may have done more harm than good

Cattle are a major driver of methane emissions.

Why Do Cows Burp Up So Much Planet-Warming Methane? A Newly Discovered Structure in Their Gut Microbes Could Be a Culprit

The “hydrogenobody” is an organelle inside certain microorganisms that live in a special stomach chamber in cattle, sheep and goats, according to a new study

Left: Experimental setup of some chickpeas growing in artificial lunar dirt. Right: A chickpea root covered in the simulated moon soil, which is sharp and glass-like. 

Hummus Made From Moon-Grown Chickpeas Might Be on the Menu for Future Lunar Residents

Researchers successfully grew and harvested chickpeas in simulated moon dirt—with a little help from worm poop and a beneficial fungus. However, they’re still testing whether the legumes are safe to eat

Microscope image of a cross-section of a mouse nose. The animal was genetically altered so that its nerve cells used for smell glow green. Some dying nerve cells appear red.

Scientists Create the First Detailed ‘Smell Map’ of Odor Sensors in the Mouse Nose—and Sniff Out Some Surprising Discoveries

In two new studies, researchers used genetic techniques to upend a longstanding assumption that nerve cells with scent detectors were randomly arranged. They don’t know whether the same spatial organization is found in human noses

The first image of newly hatched California giant salamanders in the wild can teach biologists about the nesting habitat of the little-known species.

A Snorkeling Biologist Snapped the First-Ever Photo of Newly Hatched California Giant Salamanders in the Wild. Here’s Why That’s a Big Deal

The discovery provides another key data point about a little-known species for which every observation matters

An intrepid male orangutan crosses an artificial bridge connecting trees on either side of a public road.

Watch the First Known Video of a Sumatran Orangutan Crossing a Human-Made Wildlife Bridge in the Treetops

A public road in Indonesia separates forests housing about 350 wild orangutans, among other animals. So, conservationists built several canopy bridges to prevent habitat fragmentation

African fattail scorpion (Androctonus amoreuxi)

Scorpions Are So Metal—Literally. New Images Reveal Patterns in How Their Weaponry Is Fortified With Iron, Zinc and Manganese

Scientists knew the stingers and pincers of these arachnids generally contained metals, but a new Smithsonian-led study maps out how these components are distributed

After researchers aboard the Okeanos Explorer ship couldn't figure out the orb's identity, they sent it to the Smithsonian's National Museum of Natural History for a more thorough investigation.

Cool Finds

Scientists Found This Mysterious Golden Orb on the Seafloor Nearly Three Years Ago. Now, They Finally Know What It Is

After a long, winding road of tests, researchers at the Smithsonian’s National Museum of Natural History and other institutions determined that the strange blob once attached a large sea anemone to a rock

The new Smart Cinema theater collects biometric data to track in-the-moment reactions to on-screen action.

Why Do We Love Movies? This New ‘Smart’ Movie Theater Tracks Viewers’ Brain Waves and Heart Rates to Find Out

Researchers at the University of Bristol are studying the appeal of the cinema-watching experience by turning one theater into a biometric laboratory

A female lynx named Ulcera carries a rabbit to a water trough and dunks it on July 16, 2024. This incident was one of eight that researchers recorded among lynxes in central Spain.

Camera Traps Reveal Iberian Lynxes Soaking Their Prey, a First-Ever Discovery Among Carnivores

Scientists speculate that the wild cats are trying to improve hydration or ease their cubs’ transition to solid food. The finding points to resilience in one of the world’s most endangered felines

Natural selection has been playing a bigger role in changing modern human DNA than previously thought, according to a new study.

Humans Are Still Evolving. Natural Selection Has Favored Genes Linked to Red Hair and Less Male-Pattern Baldness, a Study Suggests

A massive study of ancient and modern DNA from thousands of West Eurasian people has identified nearly 500 genetic variants that evolution has selected for or against in recent history

Bruce is missing the top half of his beak. 

A Disabled Parrot in New Zealand Became Alpha Male Thanks to His Innovative Fighting Style

A kea parrot’s half-beak became an advantage instead of a disadvantage, researchers suggest in a new study

Scientists have long assumed that queen transitions in naked mole rat colonies were always chaotic and violent. But new research suggests another, more peaceful path also exists.

Naked Mole Rats Usually Duke It Out to Choose Their Next Queen. But These Unusual Rodents May Be Capable of More Peaceful Transitions of Power

In a laboratory experiment centered around a colony known as the Amigos, researchers observed a subordinate female take over reproduction without incident

The reseachers investigated preserved specimens kept at museums, like this Bufoceratias wedli from the Field Museum in Chicago.

Anglerfish Are Known for Their Built-in Fishing Rods. New Research Sheds Light on How These Lures Evolved in the Strange Creatures

A new study suggests the odd appendages first appeared in the fish’s ancestors around 72 million years ago. Today, females might use them not only to attract prey but also to communicate with potential mates
