The Black Death may have killed more than half of Europe's population within just a few years.

A Volcanic Eruption in 1345 May Have Triggered a Chain of Events That Brought the Black Death to Europe

Ash from the explosion may have led to crop failure and famine in southern Europe, leading some Italian cities to import grain—which possibly carried fleas infected with the bubonic plague

A French physicist developed an equation to predict how things shatter. 

From Crushed Sugar Cubes to Exploded Ceramics, This Universal Law Predicts How Most Objects Will Shatter

A new equation calculates how many fragments of each size will be produced when an object breaks. The principle could help people prepare for rockfalls or other real-world scenarios

A New Trial Put Immune System-Boosting Therapies to the Test to Fight HIV, Raising Hopes for Keeping the Virus at Bay

In the small study, seven out of ten participants maintained low levels of HIV for several months after receiving the experimental treatment and stopping their usual daily medications

An image simulating the contamination from satellite trails in observations by ARRAKIHS, a European Space Agency telescope planned to launch in 2030

More Than 500,000 Satellites Are Set to Orbit Earth by 2040. They May End Up Photobombing the Images Captured by Space Telescopes

Fleets of satellites interfere with snapshots taken by Earth-bound observatories. But a new study suggests these orbiters will also contaminate observations by four space telescopes, including Hubble

A savanna in western Maharashtra, India

Ancient Literature Suggests India’s Savannas Are Much Older Than Previously Thought

Plant species mentioned in texts from the past 800 years hint the wooded grasslands of western India have been there since ancient times, pushing back on the narrative that they are remnants of long-gone forests

Researcher Carolyn Boyd examines a Pecos River style pictograph in Seminole Canyon State Park and Historic Site.  

New Research

Researchers Discover the Shocking Age of the Mysterious Pecos River Rock Art

The murals were painted on limestone canyon walls, in the same style, over the span of four millennia

Claude lived at the California Academy of Sciences for 17 years and became a beloved celebrity.

Claude, San Francisco’s Beloved Albino Alligator and ‘Unofficial Mascot,’ Dies at Age 30

Veterinarians will conduct a full exam and necropsy to determine the cause of death, but Claude had been undergoing treatment for a suspected infection in recent weeks

The World Health Organization conditionally recommends the use of GLP-1 drugs, including tirzepatide, marketed as Mounjaro and Zepbound, for obesity treatment. 

Here’s What the World Health Organization Had to Say About GLP-1s in its First-Ever Guideline on the Drugs

The health agency supports the long-term use of the medications in combination with a healthy diet and exercise, and calls for equitable access to the drugs

A supermoon in December 2017

Look Up This Week to See the Bright ‘Cold’ Moon, the Last Supermoon of the Year

December’s full moon will reach peak brightness on Thursday, but it will look striking for the next few nights—especially when it’s just above the horizon

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

A male golden pheasant (Chrysolophus pictus) with its vision-obscuring head feathers. 

For Some Male Pheasants, Love Really Is Blind. Their Elaborate Feathers That Impress Females Also Obstruct Their Vision

The adornments on the heads of male Lady Amherst’s and golden pheasants partially block their sight, according to new research, marking the first known sex-based differences in field of vision within bird species

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

Pigeons can sense magnetic fields via their inner ears, new research suggests.

Pigeons Rely on the Earth’s Magnetic Field to Navigate. Now, Researchers May Have Uncovered How They Do It

The vestibular system, a set of structures in the inner ears that helps with balance, may grant the birds their special ability

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

The National Highway Traffic Safety Administration has approved the specifications of THOR-5F, a female crash test dummy developed by Humanetics.

Will This Newly Approved Crash Test Dummy Make Car Accidents Less Deadly for Women?

The government approved the specifications of THOR-05F, marking a first step toward the government and manufacturers potentially using the dummy in future car safety tests. But it still represents only the smallest women in the United States
