Analysis of a "rusty treasure" excavated during industrial gravel extraction at Deinham, Austria, reveals it is the largest mass find of prehistoric iron bars in Europe, pointing to iron production and trade during the Iron Age on an unprecedented scale.
Before diving into the mystery of glass, theoretical physicist Corentin Laudicina takes us back to high school physics for a moment. Although he has spent years studying exactly what happens in a material during the glass transition, he also understands that his research is not
Stand on the damp sand on a California beach and chances are you're standing on top of an active earthworks site. Sand hoppers (Megalorchestia spp.), the tiny, shrimp-like creatures commonly found eating away at kelp on the shore, have been found to move massive amounts of
When asked about the greatest innovation of humans, people often say language or fire. A new paper suggests these innovations may be more interlinked than we previously assumed.
Scientists have long speculated why Venus, with a size, mass and structure similar to Earth's, doesn't have a moon. New UC Riverside research shows that our hungry twin likely swallowed it.
The sun is such a constant in our lives that it can be difficult to imagine our star ever changing. But the sun can be quite variable. There are times when its magnetic field is turbulent and generates many sunspots and other times when it is quiet and dormant. Since the 1800s,
Mitochondria—tiny structures that convert nutrients into energy—are often depicted as discrete kidney bean-shaped objects. But in reality, they form a dynamic, interconnected network throughout the entire cell, rapidly splitting and fusing as they're transported to where energy
For two weeks in September, everyone wants to be Italian—at least judging by the crowds at the annual Feast of San Gennaro in New York City's Little Italy.
In 2024, D. Sarah Stamps' team detected and tracked a short-lived bulge in the land around a volcano in Tanzania. In a paper published Sep. 18, Stamps identified the cause of the uplift: 1 million cubic meters of magma pouring into an existing magma reservoir about 1.8 miles
Social technologies, digital tools that allow people to communicate and share content with each other online, have become a central way of communicating for many people worldwide. Yet the possible effects of these technologies on the well-being and life satisfaction of regular
About 12.5 trillion tons (11.3 trillion metric tons) of ice from glaciers in Greenland and Antarctica have melted since 1979, which is enough frozen water to stack ice 5 feet (1.5 meters) deep across the continental United States, according to a major scientific report.
Common preservatives hiding in processed foods may carry unexpected heart risks, with heavy consumption linked to substantially higher rates of high blood pressure and cardiovascular disease. Researchers identified eight widely used preservatives associated with hypertension,
Cats may identify one another through a surprisingly durable chemical “calling card” made from 13 unusual fatty acids in their urine. The compounds appear linked to mysterious fat droplets in the kidneys and may represent a scent-recognition system shared across the cat family.
Researchers may have solved a long-running mystery surrounding the Dead Sea Scrolls by proposing that the Qumran sect really did use its distinctive 364-day calendar. Its perfectly ordered 52-week system kept holidays on the same weekdays, but it slowly drifted out of sync with
Scientists have developed ultra-bright nanoparticles that can detect tiny amounts of chemicals and distinguish between molecules that look almost identical. The technology could one day provide a cheaper way to catch dangerous drug impurities or trace pollutants using simple
A decade-long NIST experiment has produced a new measurement of the universal gravitational constant that differs unexpectedly from another leading result, deepening a 225-year-old physics puzzle. The discrepancy is tiny, but for one of nature’s most fundamental constants, it
Understanding how human language evolved is one of the hardest problems in science to unpick
Ancient DNA reveals that plague repeatedly returned to Europe for more than 400 years after the Black Death, evolving into new lineages and spreading through trade, migration, and war. Researchers also developed a method to date ancient plague genomes more precisely, linking
Chemical clues preserved inside fossilized T. rex teeth reveal that the dinosaur maintained a body temperature of about 97 degrees Fahrenheit, almost identical to humans. The finding provides direct evidence that the giant predator was warm-blooded, helping explain how it
Physicists have detected strong evidence that heavy, fleeting Z bosons can become quantum entangled during Higgs boson decays at CERN’s Large Hadron Collider. The result shows that Einstein’s “spooky action at a distance” survives even under some of the most extreme conditions
Nearly three decades of Hurricane Hunter data reveal four features that can help a tilted tropical cyclone straighten its circulation and become capable of intensifying. The findings could give forecasters an earlier warning that a seemingly disorganized storm is becoming
Researchers have uncovered a hidden molecular warning sign of inflammatory bowel disease (IBD) that can linger even when patients feel well and appear to be in remission. By studying around 900 human gut biopsies and patient-derived mini-intestines, the team found that
A growing Bundibugyo virus outbreak is showing how a little-known relative of Ebola can become a major threat when diagnosis and treatment options are limited. Experts warn that preparing only for familiar pathogens could leave the world vulnerable when rare but deadly viruses
Across Appalachia and the Rust Belt region, including throughout the city of Pittsburgh, former industrial sites are being transformed into new neighborhoods, research centers and technology hubs.
