New Research

For the study, the researchers worked with two adult male macaques that had previously been trained to tap in time with a metronome.

These Monkeys Learned to Tap to the Beat of the Backstreet Boys. Can They Teach Researchers About the Origins of Human Musicality?

Two macaques learned to keep time with various songs, which might point to how humans got their sense of rhythm. But some scientists doubt that the primates’ feat, which required extensive instruction, can give evolutionary clues

The Mammal With the Most Complex Milk Might Not Be Humans, After All. The Atlantic Gray Seal Could Take That Title

A new study found 332 types of complex sugar molecules in the seals’ milk, some of which help protect young from harmful bacteria. The discovery might one day help improve human health by boosting babies’ immune systems

The Burtele foot, discovered in 2009

The Human Relative Who Owned This 3.4-Million-Year-Old Foot May Have Belonged to a Species That Lived Alongside Lucy

Newfound fossils in modern-day Ethiopia suggest that the mysterious foot belonged to a recently named species, Australopithecus deyiremeda. The finding could alter the story of human evolution

The unfamiliar monk parakeets got to know each other slowly before moving on to behaviors like preening, pictured here.

Monk Parakeets Are Highly Social Birds, but They Slowly ‘Test the Waters’ When Making New Friends

The bright green parrots start with low-cost social behaviors—like sitting near each other without touching—when first interacting with unfamiliar birds within their species, possibly to avoid aggressive encounters, new research suggests

Genetic analyses revealed some of the winding paths behind the spread of domestic cats.

When Did Domestic Cats Take Over the World? New Research Suggests They Arrived in Europe and China Centuries Later Than We Thought

Two genetic analyses suggest that our feline friends reached China around 1,400 years ago via the Silk Road, and that they traveled from North Africa to Europe around 2,000 years ago

Mars regularly experiences dust storms, like this one captured by NASA's Mars Reconnaissance Orbiter in 2012. Scientists say they found evidence of "mini lightning" during some of these storms.

Scientists Say These Small Electrical Discharges May Be the First Direct Evidence of Lightning on Mars

Rather than big bolts of lightning as seen on Earth, NASA’s Perseverance rover recorded audio of small zaps similar to those from static electricity

The birch bark tar is covered in tooth marks and contains traces of saliva.

Ancient DNA Reveals That a Teenage Girl Chewed on This Wad of ‘Gum’ 10,500 Years Ago

Based on genetic material preserved in birch bark tar from Estonia, researchers found that the teen likely had brown hair and brown eyes

Both the Czechoslovakian wolfdog and the chihuahua have some recent wolf DNA, a new study suggests.

A DNA Analysis of Almost 3,000 Canines Suggests That Most Dogs Have a Little Wolf in Them

The two subspecies split about 20,000 years ago. But since then, they may have interbred more often than Smithsonian scientists thought

Researchers studied thousands of brain scans to see how the organ's architecture changes over a lifetime.

Your Brain Goes Through Five Distinct Epochs of Neural Wiring During Your Lifetime, New Research Suggests

These eras of brain architecture are marked by four major turning points, which occur around the ages of 9, 32, 66 and 83, according to a new study

A digital illustration of an HIV-infected T cell. Once infected, the immune cell is hijacked by the virus to produce and release many new viral particles before dying. As more T cells are destroyed, the immune system is progressively weakened.

New Trials Hint That ‘Functional Cure’ for HIV May Be Within Reach, Helping Some Patients Achieve Lasting Remission

People infected with HIV must take antiretroviral drugs for life. But engineered antibodies appeared to suppress the virus for certain participants in recent trials in Africa and Europe

Researchers found bird bones and jewelry, including this bowl-shaped brooch, in the grave.

Mysterious Viking Age Woman Found Buried With Scallop Shells Covering Her Mouth

Archaeologists discovered the unusual ninth-century grave on a farm along the coast of central Norway

Researchers used more than 400 samples of materials, such as this carbon-rich substance, to train and test the new A.I. system.

A.I. Reveals Signs of Early Life in 3.3-Billion-Year-Old Rocks. Next, It Could Continue the Search in Space

The new approach looks at the distribution of molecular fragments in material, allowing for broad surveys in degraded specimens

Previously, researchers assumed that much of modern dogs' diversity emerged during he past few centuries.

New Research

Dogs Have Been Surprisingly Diverse for More Than 10,000 Years, New Research Suggests

Two studies provide scientists with a more comprehensive understanding of how early dogs were domesticated as they migrated around the world alongside humans

The Altamura Man was discovered in a cave in southern Italy in 1993.

Stunningly Well-Preserved Neanderthal Skull Suggests the Species’ Large Noses Weren’t Adapted for the Cold

A new study analyzes the nasal cavity of the “Altamura Man,” a Neanderthal who died between 130,000 and 172,000 years ago

European starlings were the best at imitating R2-D2's multphonic sounds because they can control both sides of both sides of the syrinx independently, the researchers say.

Birds Are Beeping and Booping like R2-D2. Their Mimicked Sounds Are Helping Unlock the Secrets of Avian Communication

European starlings were better than parrots at imitating R2-D2’s high-pitched chattering, possibly because of their special control over a vocal organ

To survey the area, researchers used a mix of satellite imagery and magnetometry.

Archaeologists Find Evidence of a Bronze Age City in Kazakhstan

Surveyed for the first time since its discovery two decades ago, the settlement “breaks from all the things that we thought we knew about Central Asia up to this point,” a study author says

The moss spores germinated after enduring space outside of the ISS.

Moss Spores Survived Nine Months Outside the International Space Station. Then, They Grew Normally on Earth

While lunar gardens are still out of reach, the study sheds more light on terrestrial biology that may not be limited to our planet’s surface

T. oblongifolia thrives in Death Valley's high temperatures.

This Shrub Thrives in Death Valley’s Scorching Temperatures. Where Do Its Heat-Tolerant Superpowers Come From?

Tidestromia oblongifolia thrives in high heat—and scientists think it may hold the key to making food crops more resilient amid global warming

A computer simulation of a black hole being born

The Most Massive Black Hole Merger Ever Seen Was So Rare, It Seemed Impossible. Now, Astrophysicists May Finally Have an Explanation

Past research about black hole births rarely included magnetic fields or the spins of the precursor stars. But considering those factors could explain the origins of two unusual objects that collided

A raccoon peers out from a tree. New research suggests urban raccoons in the United States have shorter snouts than rural raccoons do, a sign of potential domestication.

Urban Raccoons Are Showing Signs of Early Domestication, With Shorter Snouts Than Their Rural Cousins

The shorter faces of these city-dwelling trash bandits offer a telltale sign of domestication and line up with a leading hypothesis about animals that adapt to human-dominated environments, according to a new study
