‘Stupid Hot’: Heat Waves Muddle the Minds of Animals and Humans as Confusion and Aggression Seem to Rise With the Temperature

Wide-ranging research suggests that as temperatures increase, some creatures pick fights while others struggle to learn. The findings hint at consequences that may ripple through ecosystems

Fire salamanders are among the most-studied amphibians in Europe, yet until now, no one realized they are biofluorescent.

Scientists Have Been Studying Fire Salamanders for More Than 250 Years. They Just Discovered That the Creatures Glow Under UV Light

Fire salamanders—one of Europe’s most well-researched amphibians—are biofluorescent, which means they can absorb light from an external source at one wavelength, then re-emit it at another

Queen bee larvae develop in unique peanut-shaped cells.

What Determines Royalty Among Honeybees? Not Just a Distinct Diet—Queens Also Need Specially Built Regal Chambers, a Study Suggests

The peanut-shaped compartments where future queens grow up seem to play an important role in development. The wax has chemical and physical differences from that in other parts of the hive

The team investigated numerous shipwrecks in Nassau’s harbor and nearby.

Shipwrecks Discovered Near the Bahamas Tantalize Researchers With Possible Ties to the Real Pirates of the Caribbean

A team of archaeologists and filmmakers got permission to dive in the closed zone of the Nassau harbor and discovered six wrecks, including three with suspected ties to the era of piracy

The scientists got permission to defrost the mummified remains.

Scientists Made Sourdough Bread With Yeast Found on Ötzi the Iceman’s Mummified Body

Discovered in the Alps in 1991, the remains are home to a wide variety of bacteria, fungi and yeasts

This satellite image from January 16, 2022, reveals formaldehyde in blue. The volcanic plume from the Hunga Tonga-Hunga Ha’apai volcano traveled over the South Pacific.

Tonga’s Enormous Volcanic Eruption Cleaned Up Part of Its Own Methane Emissions in 2022, Hinting at a Way to Fight Climate Change

Researchers analyzed satellite imagery of the volcanic plume and found evidence that the potent greenhouse gas had broken down. The work could inform artificial interventions aiming to mitigate global warming, scientists say

For 80 years, most mathematicians assumed Paul Erdős' strategy was correct.

Mathematicians Puzzled Over a Famous Problem for 80 Years. Now, They’ve Used A.I. to Identify a Clever Solution

In 1946, the mathematician Paul Erdős posed the unit distance problem—and suggested a winning strategy. An A.I. model has now landed on a better one. Why didn’t humans get there first?

Pigeons that had been injected with a drug to deplete their special liver cells did not find their way home until the sun came out.

How Do Pigeons Find Their Way Home? New Research Suggests That the Birds’ Remarkable Navigational Skills Come From Their Livers

The birds might use the organs’ iron-rich immune cells as internal compasses on overcast days, when they must rely on Earth’s magnetic field, instead of the sun’s light cues, for navigation

Cool Finds

A Century After Causing Controversy, Red Cave Markings in Wales Are Classified Again as Britain’s Oldest Rock Art

The team of scientists used modern dating methods to confirm an old hypothesis by the rock art’s initial discoverers

A microscope image of tissue taken from a sea cucumber. The green coloring indicates cellular activity.

Scientists Say They’ve Discovered ‘Little Lab Zombies’—Seemingly Immortal Tissue Taken From Sea Cucumbers

Chunks removed from the marine creatures more than three years ago haven’t degraded and show signs of biological activity, raising questions about what it means to be alive

Chimpanzees, bonobos and gorillas tend to walk on their knuckles, while macaques and capuchins walk with flat palms.  

Did Human Ancestors Walk on Their Knuckles Like Today’s Chimpanzees? New Research Adds More Evidence to the Debate

After investigating thousands of wrist bones, scientists suspect the last common ancestor species of humans and chimpanzees may have navigated the world on its knuckles

Could Bug Spray Attract Mosquitoes? Lab Insects Learned That the Smell of DEET Would Lead Them to a Tasty Treat

Researchers don’t know how the findings might overlap with real-world settings. But the discovery suggests that we’re most vulnerable when our insect repellent is wearing off, meaning we should reapply it regularly

New Research

These 600-Year-Old Chinese Surgical Instruments Are Coated in an Early Local Anesthetic—Carefully Extracted From a Poisonous Plant

Researchers say the numbing agent splashed onto iron scissors and tweezers during a procedure. They were found in a Ming dynasty doctor’s tomb

A large hailstone made up of an aggregate of smaller ice particles

Giant, Destructive Hail Is Becoming More Common With Climate Change, Study Says

As the atmosphere warms, the potential for hail as large as a grapefruit is growing

The Cerne Abbas Giant lies on a hillside.

England’s Most Famous Naked Giant Will Glow White Again, Thanks to Help From Hundreds of People Performing a Ritual of Restoration

The Cerne Abbas Giant, a 180-foot-tall geoglyph in southern England, is getting a new layer of chalk

Western Australia’s Ningaloo coast

Scientists Detect an Elusive Giant Squid and Many Other Surprising Marine Animals Near Western Australia Thanks to DNA in the Water

Mucus, feces, skin and other shed tissue allowed researchers to investigate which creatures have been swimming in two deep-sea canyons without having to observe or catch them

Human development—such as roads—affects wildlife. But so does the presence of people.

The Mere Presence of Humans—Not Just Our Changes to the Land—Can Alter Wild Animals’ Behaviors, a New Study Suggests

Researchers examined GPS tracking data from thousands of animals representing 37 species and anonymized cellphone location data from 2020, a year of Covid-19 lockdowns, and the previous year

An artistic rendering of Tylosaurus rex

Paleontologists Discover an Ancient Marine Reptile They’ve Dubbed the T. Rex of the Sea, Crowning Another King of the Cretaceous

Scientists figured out that the predators were lumped in with a previously named mosasaur species. The new one, called Tylosaurus rex, could grow to 43 feet long, about the length of a school bus

Built roughly 4,600 years ago, the Great Pyramid of Giza has survived several significant earthquakes.

Ancient Egyptian Engineering Choices Helped the Great Pyramid of Giza Survive Earthquakes, New Research Finds

Researchers measured vibrations inside and around the pyramid to learn that the structure is surprisingly resilient against seismic tremors

The researchers studied four captive belugas housed at the New York Aquarium of the Wildlife Conservation Society.

Belugas Can Recognize Themselves in Mirrors, Joining a Short List of Nonhuman Species That Show Signs of Self-Awareness

The researchers hope that this new understanding of cognition in the toothed whales will increase human empathy and concern for the animals, leading to more efforts to protect them
