Science, engineering, and discovery — the research and breakthroughs that matter.

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 i

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 is

Sacred springs of South Africa—pure waters or polluted? We found tiny bits of plastic in the samples we tested and more — today's student signal.

Across South Africa, natural springs are more than sources of freshwater. Some are places of healing, spiritual cleansing and rituals, where communities collect water and maintain longstanding cultural connections with the environment. For example, during cleansing rituals, peopl

When you were in school, what stressed you out the most? For many students, classroom assessments—graded tests, quizzes, group work, presentations, labs and the like—would be near the top of the list.

Complex systems may work better when their parts are not perfectly alike. Northwestern physicists found that carefully balanced variation, or “disorder,” can make networks such as power grids, ecosystems, neurons, and materials more stable. Even random differences sometimes impro

Across the country, kids are settling into new school-year routines. Parents buy backpacks, teachers arrange desks and lesson plans, and friends reconnect. But in recent years, empty chairs are becoming a more common sight—especially in classrooms where students are already facin

Amino acids and a bone mineral may help control magnesium implant breakdown, three student papers suggest and more — today's student signal.

Seeing a bachelor's thesis published in a scientific journal is relatively uncommon. For three theses linked to the same research group to result in scientific publications within just three months is downright rare. Yet that is exactly what has happened in Elsebeth Schröder's re

Physicists at UC Santa Barbara have extended the search for evidence of microscopic black holes produced at the Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN). The formation of these tiny, fleeting objects at the LHC represents one way theori

Research from Queen Mary University of London explores how combining learner autonomy with student-led inquiry can create a more engaging and collaborative experience for international students learning academic English.

Each summer, researchers from Hokkaido University returned to the Qaanaaq Ice Cap in northwestern Greenland to measure changes in the ice surface using aluminum poles drilled into the ice. Their 13-year record shows how the ice cap changed from 2012 to 2025.

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 sand,

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, w

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 (2.9

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 us

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.

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.
