Scientists studied the sweat bee species Megalopta genalis​​​​​​, native to Central and South America.

In This Bee Species, Why Do Some Daughters Leave Home While Others Stay ‘Bee-hind’ to Help Mom?

Biologists at the Smithsonian Tropical Research Institute investigated a flexible social bee species, which helps shed light on the evolution of more complex organizational structures among other insects

Keep an Eye Out for Two Stellar Meteor Showers Peaking This Week, the Southern Delta Aquariids and the Alpha Capricornids

A nearly full moon may obscure the fireballs falling from the remains of two comets that passed through Earth’s orbit

Experts attached a satellite transmitter to Pancake's shell, which will track its location for up to 90 days.

An Endangered Kemp’s Ridley Sea Turtle Named Pancake Makes a Triumphant Return to the Ocean After Months of Rehabilitation

The cold-stunned turtle was rescued last fall on Cape Cod and has since made a full recovery. The reptile, whose sex remains unknown, is estimated to be between 2 and 5 years old and weighed 11 pounds at the time of release

The new work contributes to a broader shift in bilingualism research, which is moving toward the view that grammar is supported by a shared, flexible brain mechanism that operates across all languages.

How Does a Bilingual Speaker’s Brain Process Two Languages? New Research Suggests That Both Rely on the Same Neural Wiring

Scientists have long wondered whether different neural mechanisms govern each language within a bilingual speaker’s brain. A recent study of people who speak both English and Spanish hints at a single “grammatical engine”

An A.I. model from Anthropic helped disprove a longstanding conjecture in mathematics.

A.I. Disproves a Decades-Old Mathematical Idea, the ‘Biggest Conjecture’ That the Tech Has Played a Role in Yet

A mathematician announced that he used one of Anthropic’s A.I. models to find a counterexample to a problem called the Jacobian conjecture. While experts consider it a milestone, the work raises questions about the future of mathematical research

Male chimpanzees were more likely to exchange friendly touches with other males—like Little Jake and Little Joey shown here.

Chimpanzees and Bonobos Use Hugs, Kisses and Friendly Pats to Keep the Peace, Just Like Humans, a New Study Suggests

Since all three ape species diverged from a common ancestor that lived roughly six million to eight million years ago, the findings hint that friendly touching to diffuse tension has deep evolutionary origins

Getting the device to transition between air and water seamlessly was one of the most challenging aspects of the work.

This Robot Can Flap Its Wings to Both Fly and Swim. It Might One Day Help Scientists Study Diving Birds and Survey Ocean Habitats

The bioinspired device, which weighs roughly half a pound and measures around three feet wide, was also modeled after aquatic birds like puffins, gulls and loons

Is This Giant Celestial Body a Moon, a Planet or Something in Between? The Strange Object Calls Astronomical Labels Into Question

The newly found object, estimated to be roughly as massive as Jupiter, orbits a brown dwarf—a “failed star”—which in turn circles a small star. For now, researchers are calling the puzzling body an “exosatellite”

In the Sundarbans, the world's largest mangrove forest, a juvenile Bengal tiger steps from the shadows of mangroves into a tidal creek. This photo was highly commended in the mammals category.

Mangroves Are Key to Coastal Ecosystems. See 20 Breathtaking Photos That Reveal How the Trees Support Wildlife and Face Threats

The Mangrove Photography Awards honor images that show off the beauty—and the fragility—of these valuable intertidal forests

A mother floating belly-up next to her calf

Why Are These Whales Floating Upside-Down? They Might Just Be Moms Who Need a Break From Feeding Their Babies

Each year, southern right whales migrate thousands of miles from their feeding grounds to breed, give birth and raise their young. Taking rests and regulating their calves’ nursing schedules might help mothers conserve energy while they’re far from food

The drug targets the tau protein, which accumulates and forms tangles (seen in blue) in nerve cells.

Experimental Alzheimer’s Drug That Fights a Tough-to-Target Protein Shows Promise at Slowing Cognitive Decline in a Clinical Trial

Recently FDA-approved treatments work to clear clumps of the protein amyloid beta in the brain. A drug that instead goes after tangles of the protein tau can yield similar cognitive outcomes, a new study suggests

The brown trout were likely introduced to guarantee a food source if reindeer hunts were unsuccessful, according to a new study.

Hunter-Gatherers Brought Trout to a Norwegian Mountain Lake 7,000 Years Ago, the Earliest Known Example of Humans Translocating Fish

Researchers have long known that the animals were introduced into the region’s high-altitude bodies of water, but they weren’t sure when it happened or whether humans had a hand. Analyses of recently discovered ancient fish traps provide new clues

Overall, the 16 participants of the study were “largely positive” about their interactions with griefbots, the scientists write in the paper.

Would You Chat With an A.I. ‘Ghost’ of a Deceased Loved One? New Research Suggests That the Tech Can Provide Comfort and Closure

Commercial “griefbots” are becoming more popular, and many experts have questions about their psychological and ethical impacts. A new study aims to ensure that the bots are designed responsibly

A new study documents two incidents of orcas breaking sunfish into pieces.

Video Captures Orcas Ramming a Sunfish So Hard It Explodes. The Mysterious Behavior Might Be a Form of Play or Juvenile Care

In two incidents documented in Mexico’s Gulf of California, orcas worked together to blast sunfish into smithereens after they had killed the enormous animals

The upper stage of a SpaceX Falcon 9 rocket is estimated to hit the moon on August 5.

A SpaceX Rocket Part Is Expected to Smack Into the Moon in August, Highlighting the Growing Problem of Space Junk

The unintended event also creates an opportunity for scientists and skywatchers to witness lunar impact dynamics in real time, although the debris will hit a sunlit portion of the moon from the perspective of Earth, making it hard to see

Handedness refers to both hand preference and hand dominance. 

People Aren’t Born as Righties or Lefties—They Develop Hand Dominance With Practice, a New Study Suggests

Humans do have a biological preference for using one side of their body, which might prime them for using limbs on that side for complex motor tasks like writing—and honing those skills over time

When they hatch, echidna puggles are about the size of a jellybean and weigh half as much as a mini marshmallow.

Double Puggles: See the Adorable ‘Twin’ Echidnas Born at the San Diego Zoo Safari Park

The two babies hatched this year to one mother during the same breeding season—an extremely rare occurrence, according to the San Diego Zoo Wildlife Alliance

A pregnant naked mole-rat queen, on the left, and a worker, on the right, sniff each other.

Naked Mole-Rat Queens Emit a Special Scent to Stop Their Rivals From Reproducing, a New Study Suggests

The strange-looking creatures are one of two known mammals that use a social structure like that of bees and ants. A ruling rodent maintains power over her colony via one key chemical compound, according to new research

An artistic rendering of LHS 1140 b and its host star, with another smaller exoplanet orbiting nearby.

Could Life Exist on This Nearby World? In a First, Astronomers Find an Atmosphere on an Earth-Like Exoplanet in the Habitable Zone

While the celestial body seems to host three features that could make a livable environment—an atmosphere, a rocky composition and a temperature that could allow liquid water to sit on the surface—researchers have not currently detected any residents

An amateur astronomer thought he found an impact crater on Google Maps. Then, an expedition to the site confirmed that he was right.

Cool Finds

An Amateur Astronomer Using Google Maps Spotted a Strange Indentation. It Turned Out to Be a Meteorite Crater From 390 Million Years Ago

Scientists confirmed the astronomer’s suspicions with an expedition to the site in Quebec. The discovery offers a rare case of a reported new crater turning out to be real
