Classic feline behavior could be a passive-aggressive maneuver to get what they want

Two new studies suggest that smartphones are partially to blame for declining birth rates.

Smartphones Might Be Playing a Role in the United States’ Declining Birth Rate, New Research Suggests

Some economists suspect that the technology’s widespread adoption has reduced in-person interactions and increased access to pornography and information on birth control, leading to less unprotected sex

Researchers observed seafloor movement at the Southeast Indian Ridge, denoted by the yellow line.

In a First, Scientists Witness the Seafloor Spread in Real Time, Giving Them a Rare Glimpse at a Mysterious Geologic Process

Across a matter of days in 2024, the seafloor in part of the Indian Ocean dropped by about 13 feet, and roughly 5.7 billion cubic feet of molten rock rose to the crust’s surface, according to a new study

Sotheby's is auctioning one of the largest and most complete T. rex skeletons ever found.

This T. Rex Fossil Could Fetch the Largest Sum of Any Dinosaur Ever Auctioned. Scientists Worry They’ll Lose the Chance to Study It

Bids on “Gus” will start at $19 million, a steep price for public institutions. Specimens in private collections can be harder for researchers to examine, and they’re practically impossible to include in studies in top-tier scientific journals

About two-thirds of the analyzed fossils were bent left, which means that the animals were curved right when they were alive.

Meet the Earliest Known ‘Right-Handed’ Animal, a Worm-Like Creature That Lived About 550 Million Years Ago

During the Ediacaran period, the critter wriggled around on the ocean floor of what’s now South Australia and preferred to turn right, a fossil analysis suggests

Earth is currently experiencing an occurrence of the El Niño climate pattern.

Could We Mitigate Super El Niños by Artificially Changing the Climate? A New Study Indicates Yes

Researchers used computer models to see what would have happened had scientists caused marine cloud brightening in the face of strong past El Niños

Kazakhstan’s Iron Age ‘Golden Man’ and Other Elite Scythians of Eurasia Inherited Their High Social Status, Ancient DNA Suggests

Researchers have long wondered whether upper-class members of the ancient nomadic warriors earned their social status through individual achievements or birthright

Strange, metallic-looking spheres recently washed ashore in Queensland, Australia.

Strange Spheres Washed Ashore on an Australian Beach. Authorities Say They’re Probably ‘Space Balls’—Empty Fuel Vessels From a Rocket

The shiny objects—each roughly twice the size of a basketball—began to appear on July 3. Authorities initially worried that they were hazardous but have since determined that they’re likely safe bits of space junk

The Rumkale fortress ruins sit on the banks of the Euphrates River in Turkey.

Scientists May Have Discovered the Origins of the Euphrates River, Which Helped Nurture Some of the Earliest Known Civilizations

The famous waterway began as two rivers, a new study suggests. Tectonic activity around five million years ago probably made them change course and merge, helping to birth the Fertile Crescent

Chinese money plant

Researchers Find a Mathematical Pattern Used in City Planning Hidden in the Leaves of a Common Houseplant

The major veins of Chinese money plant leaves form what’s called a Voronoi diagram. It might be caused by a plant-growth hormone that emanates in waves from developing leaves’ pores

Researchers created a map of arbuscular mycorrhizal fungal networks across Earth's topsoil.

Nearly All Plants Depend on Tiny Underground Fungi. The Microbes’ Vast Global Networks Were Just Mapped for the First Time

If lined up end to end, the thin, tubular threads that make up the arbuscular mycorrhizal fungal networks in Earth’s topsoil could stretch between our planet and the sun almost one billion times

About two-thirds of patients ages 40 and older with a common form of breast cancer might be able to forego chemotherapy—usually delivered intravenously—as part of their treatment plans.

This ‘Practice-Changing’ Gene Test Could Tell Doctors Which Patients With Breast Cancer Can Skip Chemo, Clinical Trial Suggests

Chemotherapy comes with debilitating side effects, including brain fog, nausea and nerve damage. New research suggests that many people with a common type of breast cancer need just radiation and hormone therapy to prevent recurrence

Venus flytraps and other carnivorous plants have long intrigued scientists, including English naturalist Charles Darwin.

Venus Flytraps Snap Their Traps Shut in Less Than a Second. Scientists Say They’ve Discovered How the Predatory Plants Are So Fast

The walls of cells in the leaves’ outer layer suddenly soften, allowing the structures to hinge into a closed position, according to a new study

How teenage participants moved on a schoolground in Spain. 

Researchers Accidentally Discover That Humans Prefer to Turn Counterclockwise. But They Still Have No Idea Why

The effect transcends factors like culture, gender and handedness, causing the scientists, who were initially studying social distancing behavior, to scratch their heads

A team of researchers put out information about a fake disease, and A.I.-powered chatbots fell for it.

Scientists Invented a Disease to Test Whether A.I. Knew It Was Fake. Then, Chatbots Started Saying It Was Real

The eye condition bixonimania doesn’t exist, but neither bots nor some researchers caught that the content was fabricated—despite obvious clues

Researchers recovered environmental DNA from ancient ground squirrel poop.

Researchers Investigated Ancient Squirrel Poop Frozen in Permafrost and Found Enlightening Details About the Animal’s Ecosystem

Up to 700,000 years ago, ground squirrels in modern-day Canada collected tons of helpful genetic information on their bygone environment through their diet

In many animal species, males display showier features than females. Among humans, however, women are popularly described as the "fairer sex."

People Across Cultures Find Women’s Faces to Be More Attractive Than Men’s, a New Study Suggests

In many species of wild animals, males have flashier features than females to help them attract mates. But scientists have long noticed that humans seem to be an exception, with women often being considered the “fairer sex”

Meet the ‘Witch Croc,’ a Strange Ancient Crocodile Relative With Two Legs and No Teeth That Roamed New Mexico During the Triassic

The reptile, a dinosaur look-alike called a shuvosaur, represents a long-awaited discovery that helps paleontologists fill a gap in the fossil record

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

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
