The climate-altering eruption came from the Zavaritskii volcano on an uninhabited island in the Pacific that once hosted a Soviet submarine base, according to a new study

At the same time as the Romans were building the Colosseum, they were also breathing in high amounts of toxic lead from silver mining and smelting operations.

Ancient Romans Breathed in Enough Lead to Lower Their IQs, Study Finds. Did That Toxin Contribute to the Empire’s Fall?

Using Arctic ice core samples, researchers estimate silver mining and smelting released enough lead during the Pax Romana to cause a 2.5- to 3-point drop in IQ

The U.S. surgeon general wants updated warning labels on alcoholic beverages that highlight the increased risk of cancer tied to drinking alcohol.

Alcohol Consumption Raises the Risk of Seven Cancers, Says U.S. Surgeon General in a New Health Advisory

The “Nation’s Doctor” has called for a cancer warning label on alcoholic beverages and suggests the recommended limits for alcohol consumption should be reassessed

Imperial Geyser is one of the many hydrothermal features that draw visitors to Yellowstone National Park.

Will Yellowstone Erupt Soon? Scientists Are Using New Techniques to Find Out

From Chimps Eating Medicinal Plants to Footprints Tracking Our Early Relatives, Here Are the Most Significant Human Evolution Discoveries of 2024

Smithsonian paleoanthropologists explore how the year brought us closer to understanding ancient human relatives and origins

A cast of a Neanderthal skull at the Chemnitz State Museum of Archaeology in Germany. New research delves into when humans and Neanderthals interbred.

Researchers Track Down When Neanderthals and Early Modern Humans Interbred Using Ancient Genomes

Two studies came to a similar conclusion, highlighting a single, sustained event of mixing DNA. The findings could impact our understanding of when modern humans reached regions like East Asia and Australia

Researchers calculated that the human brain processes thought at a speed of ten bits per second.

The Speed of Human Thought Is Far Slower Than the Average Wi-Fi, Study Suggests

But the rate that we gather sensory data is 100 million times faster than our thought processes, making our brains champions at filtering information from our chaotic surroundings

Southern sea otters are making a comeback along the coast of California—and they're chowing down on invasive European green crabs.

Hungry Sea Otters Are Taking a Bite Out of California’s Invasive Crab Problem, New Study Finds

Researchers estimate southern sea otters eat up to 120,000 European green crabs per year at the Elkhorn Slough National Estuarine Research Reserve

From these upper hip bones, researchers extracted an ancient genome of the bacteria that causes syphilis.

Expedition Discovers 27 New Species in Peru, From an ‘Exceedingly Rare’ Amphibious Mouse to a Blob-Headed Fish

The hidden creatures were found in a densely populated region known for its successful—and controversial—conservation tactics

Researchers made replicas of Neolithic clay trays and baked their own focaccia bread.

New Research

Scientists Say Bakers Were Making an Early Version of Focaccia Bread 9,000 Years Ago

New research suggests that Neolithic communities living in the Middle East experimented with recipes and baked large flatbreads between 7000 and 5000 B.C.E.

Researchers looked at brain scan data and results from blood tests to search for correlation between certain proteins and brain aging.

Researchers Find 13 Proteins in the Blood That Are Seemingly Linked to Brain Aging

Though experts say more work is needed to understand the findings, this line of study might offer a way to monitor age-related cognitive disorders and target treatment

A California ground squirrel carries a vole in its mouth after hunting the rodent.

Squirrels Are Displaying ‘Widespread Carnivorous Behavior’ for the First Time in a California Park, New Study Finds

The familiar rodents, known for eating nuts and seeds, have been spotted hunting and decapitating voles in a gruesome dietary adaptation. Scientists say it might signal resiliency in face of future environmental pressures

During a systematic metal detector survey in southern Arizona, Deni Seymour unearthed a 16th-century cannon likely left behind by Spanish conquistadors.
