The right side of the bird's body is male while the left side is female.

An ‘Extremely Rare’ Half-Male, Half-Female Bird Temporarily Took Up Residence Outside of Chicago

The unusual-looking bobolink is what’s called a bilateral gynandromorph. The bird behaved like a male, eventually wooing a mate and raising fledglings

NASA-Funded Mission to Rescue a Falling Space Telescope Officially Ends in Failure

The commercial LINK spacecraft was supposed to give NASA’s Swift observatory a boost, pushing it higher into orbit to extend its life. But after launch, LINK experienced several problems. Swift is expected to re-enter Earth’s atmosphere and burn up by the end of this year

Narwhals live in the North Atlantic and Arctic Oceans.

Narwhals Sport Iconic Straight, Spiraled Tusks. Scientists Just Uncovered Some of the Eye-Catching Feature’s Structural Secrets

The Arctic whales are the only known animals with straight tusks, and ones that consistently twist to the left. New research reveals that the inner layer twists to the right and that the opposing spirals provide strength and help the tusks grow straight

An aerial view of the mass grave, which was found beneath a soccer field in Vienna in October 2024

New Research

Construction in Austria Revealed a Roman-Era Mass Grave Beneath a Soccer Field. New Research Suggests That the Men’s Enemies Targeted Their ‘Sensitive Areas’

No written records mention a fight in this specific part of Vienna at the time of the men’s deaths. But the brutal nature of their injuries, particularly to the pelvis area, indicates that these individuals died on the battlefield

Scientists suspect the bones belonged to a brown bear or a polar bear.

Ireland’s ‘Kerry Cow’ Bones Are Actually Wild Boar and Bear, Shaking Up the Story of Farming’s Arrival on the Island

The bones were discovered on the Dingle Peninsula more than 30 years ago, but scientists recently decided to take another look at them, this time using modern techniques

Scientists have discovered more than 4,400 ancient preserved human brains, some of which are 12,000 years old.

Archaeologists Have Found Thousands of Intact Ancient Human Brains. Scientists Say They’ve Figured Out Why the Organs Don’t Always Rot

Under the right conditions—wet and oxygen-deprived—the same chemical reactions that cause tissue to break down can instead have the opposite effect, according to a new study

A swarm of Chaoborus edulis flies over Lake Malawi

Why Don’t Insects Live in the Ocean? Scientists Just Ruled Out One Possible Explanation Thanks to Deep-Diving Fly Larvae

Researchers thought that insects might not live there because their respiratory systems would implode from water pressure. But certain fly larvae in East Africa make daily trips toward the bottom of Lake Malawi with the help of strong air sacs that contain a stretchy protein

Researchers made the discovery while studying the California two-spot octopus.

Why Are Some Octopuses So Smart? The Answer Might Lie in a Never-Before-Seen Mutation That Helps Them Accurately Build Proteins

Scientists discovered a strange feature in certain octopuses’ ribosomal RNA, molecules that create a 3D scaffold for cellular protein factories. It was found only in shallow-water creatures that have expanded nervous systems and can do complex behaviors

Brazil experienced its first urban outbreak of yellow fever in decades from late 2016 through 2018. During that time, people flocked to health centers to get a vaccine, which can provide lifelong protection.

Brazil’s First Urban Yellow Fever Outbreak in Nearly a Century May Have Been Fueled by a Surprising Culprit

Extremely wet conditions are known to help spread mosquito-borne diseases like yellow fever. But based on computer simulations, researchers suspect that a severe drought may have contributed to the South American country’s recent deadly epidemic

A tufted gray langur strokes a grizzled giant squirrel in Yala National Park, Sri Lanka.

Do Monkeys Keep Pets? Study Finds Widespread Primate Interactions With Other Animal Species, From Mice to Deer

This social behavior might reveal the evolutionary roots of traits that underlie pet-keeping in humans, scientists say, from caregiving to tolerance and curiosity. But it’s not the same as a person keeping a cat or a dog

Participating in a sleep study, or a polysomnography, can help doctors diagnose a patient with narcolepsy.

This Newly Approved Narcolepsy Drug Is the First to Target the Sleep Disorder’s Root Cause Rather Than Its Symptoms

The Food and Drug Administration just greenlit a medication called Orzeyful for the treatment of narcolepsy type 1 in adults. The condition is caused by the loss of brain cells that produce orexin, a chemical important for regulating the sleep-wake cycle

These Coral Reefs Off West Africa Were Long Presumed Dead. Scientists Just Found Them Alive and Teeming With Life

Fish surveys in the 1960s detected what experts thought was a dead coral reef barrier off the country of Benin. Decades later, researchers set off in small fishing boats to investigate it using sonar mapping, underwater drone surveys and stationary video recorders

Past studies have suggested that what’s good for the heart may also help protect the brain. But researchers hoped to frame that connection in a different way—not just as reduced risk, but as time gained without dementia.

Avoiding These Three Vascular Health Risk Factors in Midlife Can Help You Delay Dementia for About 13 Years, Study Suggests

High blood pressure, diabetes and smoking are three major modifiable risk factors of dementia. New research tracked more than 12,000 participants to quantify how many years of healthy cognitive function you can gain by evading some or all of them during middle age

A map of the galaxy J0148-4214 with dots showing the locations of the three supermassive black holes.

In a First, Astronomers May Have Spotted a Galaxy in the Early Universe With Three Behemoth Black Holes

The galaxy’s light took about 12.5 billion years to reach the James Webb Space Telescope, meaning the instrument saw the black holes a little more than one billion years after the Big Bang. Two of the black holes seemed on track to merge, illustrating how the objects grow

When Did Animals Start Giving Birth to Live Young? This 236-Million-Year-Old Fossil Might Rewrite Mammals’ Evolutionary History

A bone feature found in a mammal ancestor hints that the creature was relatively large as a newborn, more in line with the size of a creature birthed live than hatched from an egg. Still, it provides only indirect evidence

Running with a stroller is a safe way to get some exercise when your kids are young, new research suggests.

Listen Up, Parents: Running With a Stroller Might Make You Less Prone to Overuse Injuries

Runners often experience conditions like shin splints, runner’s knee and plantar fasciitis, which causes pain in the bottom of the heel. But pushing a stroller’s handlebar seems to make you distribute your weight differently

 SARS-CoV-2, the virus that causes Covid-19, under the microscope

Covid-19 Can Reawaken Dormant Viruses in the Body, Which Might Worsen Symptoms of the Respiratory Illness, Study Suggests

Most people carry a sleeping virus in their bodies, such as the herpesvirus that causes mononucleosis, or the “kissing disease.” A new study hints that Covid-19 triggers their reactivation, which could worsen symptoms and increase the risk of long Covid

A modern-day view of Stirling Castle, the Scottish stronghold where the skeleton was found in 1997

A Medieval Man’s Injuries Reminded One Archaeologist of Modern-Day Car Crash Victims. They Turned Out to Be the Work of an English Trebuchet

A skeleton unearthed in Scotland likely belongs to a soldier struck by a high-speed projectile during Edward I’s 1304 siege of Stirling Castle. The man suffered more than 160 fractures

Astronomers Peered at the Early Universe and May Have Discovered a New Kind of Celestial Object: Black Hole Stars

Since the James Webb Space Telescope started collecting data in 2022, it has found puzzling objects dubbed little red dots. A new study suggests they might be giant black holes with some characteristics of stars

Redback spiders live throughout Australia.

Here’s Why These Male Spiders Sacrifice Themselves by Somersaulting Into Females’ Fangs While Mating

A new study suggest that even strange, complex animal behaviors can have a relatively simple genetic basis
