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

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

Neptune, which appears blue because of methane in its atmosphere, has a strange set of moons.

Neptune’s Moon Nereid Might Be the Sole Intact Survivor of an Ancient Lunar Collision

A study suggests that the ice giant’s largest moon, Triton, made a dramatic entrance to the Neptunian system long ago, kicking Nereid outward and destroying the planet’s other original lunar companions

Around 90 percent of people are right-handed.

Why Is Nearly Every Person Right-Handed—but Not Every Ape and Monkey? New Research Explores the Evolutionary Origins of Human Handedness

Brain size and bipedalism are the most likely drivers of our species’ right-hand dominance, according to new research

The exterior of the reconstructed chapel in Historic St. Mary's City, Maryland

Groundbreaking DNA Analysis Identifies 1.3 Million Living Relatives of Colonial Maryland’s Earliest Settlers

Experts compared DNA from 49 skeletons buried in a cemetery in St. Mary’s City to genetic data shared by 11.5 million 23andMe users. They also identified what may be the remains of the colony’s second governor

Mediterranean monk seals are among the rarest pinnipeds in the world.

Mediterranean Monk Seals Hide in Underwater ‘Bubble Caves’ to Avoid Tourists During the Busy Summer Season, a Study Suggests

Researchers caught the rare pinnipeds resting and sleeping in a secluded chamber on the Greek islet of Formicula. The findings suggest that these small caves should be included in efforts to protect the animals’ habitat

Researchers collected groundwater in boreholes up to 1.8 miles underground. The water contains dissolved natural hydrogen.

This Canadian Mine Might Release Enough Natural Hydrogen Each Year to Power 400 Homes, Hinting at an Untapped Source of Clean Energy

Many of the country’s metal mines are embedded in an ancient rock formation that probably also houses a lot of the resource, referred to as “white hydrogen”

The Plain of Jars is an archaeological site with thousands of stone jars in Laos.

A Discovered Trove of Bones and Teeth Yields New Clues to the Century-Old Mystery of ‘Death Jars’ in Laos

Scientists found bones of 37 people inside a giant stone jar at one of Southeast Asia’s most puzzling archaeological sites. The find suggests a multigenerational burial practice

Gentoo penguins have been considered a rare beneficiary of climate change due to their population growth on the Antarctic Peninsula. Splitting the birds into four species brings to light regional threats and declines.

Gentoo Penguins Are Actually Four Different Species, Scientists Say, Revealing They’re Not Quite ‘Winners’ of Climate Change After All

A new study indicates that the adaptable birds evolved into distinct lineages as isolated populations shifted to match their environmental conditions over time. The work has implications for how conservationists assess threats to gentoos
