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

Students who open a personal social media account earlier in adolescence appear to perform worse on later standardized tests, according to a study in Nature Human Behaviour based on 5,227 Italian students. The authors speculate that these differences may be attributable to excess

If you build a house in the United States today, there's a good chance you'll be living under the dictates of a neighborhood homeowners association—roughly two out of every three new homes are in an HOA, as are a third of existing homes.

Low river discharge reduces the likelihood of young Atlantic salmon reaching the North Sea. Fewer salmon reach the Haringvliet sluices, and their passage takes longer, making them more likely to fall prey to predators. Using so-called predation tags, researchers were able to demo

Risso's dolphins around the British Isles are part of a single population—genetically distinct from those elsewhere in the Atlantic, new research shows. Scientists studied the DNA of dolphins that stranded in England, Scotland and Wales from 1992 to 2016.

For male humpback whales, singing is serious business. Their haunting, complex songs can last for hours and travel for miles underwater, playing a central role in reproduction during the winter breeding season. But despite decades of research into what these songs sound like, sci

Speak into a phone and an app can render your words in another language in seconds. AI-powered speech translation can be fast, convenient and fluent. But fluency does not guarantee that people will understand one another.

Hidden moon ice may reveal itself through the way it bends and reflects vibrations from moonquakes. The technique could help astronauts locate vital water supplies and uncover clues about the origins of Earth’s oceans.

We have known for a while that the Milky Way is full of homeless worlds. Rogue planets, free-floating planets—call them what you like—but they are planets formed in orderly systems around ordinary stars and then thrown out, either by a gravitational shove from a sibling planet or

Rideshare launches boost regional GDP and flexible jobs, study finds and more — today's student signal.

Ride-hailing has become a routine part of urban life in the United States, but its broader economic impacts have been difficult to measure. As Uber and Lyft expanded across hundreds of cities over the past decade, they promised more flexible work for drivers and convenience for p

How do students actually use AI learning assistants? A new research paper by IU International University of Applied Sciences provides the first robust answers to this question. For the study "Using AI-based Learning Assistants in Higher Education: A Large-Scale Descriptive Analys

"An island of biodiversity in a sea of monoculture": This is how a recent study characterized the Pimentel Barbosa Indigenous Territory (TIPB), located in the northeastern part of Mato Grosso state in Brazil's Central-West region. The study showed that the area's human occupation

Admissions applications, discussion posts, grades, and activity logs are among the most common signals educators use to gauge whether students will thrive in an online program. But two new Georgia Tech studies suggest those measures tell only part of the story.

Students who open a personal social media account earlier in adolescence appear to perform worse on later standardized tests, according to a study in Nature Human Behaviour based on 5,227 Italian students. The authors speculate that these differences may be attributable to excess

An international research team led by Assistant Professor Ryuji Takasaki of the Faculty of Biosphere-Geosphere Science at Okayama University of Science has published a paper proposing a new hypothesis on the evolutionary history of dinosaur digestive systems by focusing on gastro

A study from the University of Manchester into the effects of polymer cross-contamination on the outcome of mechanically recycling plastics has found that the presence of contaminants radically alters degradation mechanisms.

Ants live in highly organized colonies and cooperate daily to tackle a wide range of problems. Their striking group behaviors have fascinated biologists for centuries and even inspired the development of various artificial intelligence (AI) systems.

So far, almost all stellar-mass black holes detected by astronomers have been found in binary systems. However, astronomers have long suspected that these binary black holes are the exception and that, within the Milky Way, most exist on their own.

Roll back the tape of Earth's history, and geologists and astrobiologists remain perplexed about the environmental conditions on early Earth. That's because conventional pathways for understanding Earth's history have been lost to time owing to the planet's active geology and atm

Cyanobacterial blooms, like the ones that occur in Lake Geneva, are rapid, dense growths of photosynthetic bacteria in fresh and marine waters that can threaten the health of swimmers and their pets.

When a hurricane roars toward land, forecasters try to predict how high sea levels will rise to help coastal communities prepare for the worst impacts.

Imagine trying to swallow a sip of water while your face feels stuffed with congestion, your sense of taste is dulled and your body is floating 250 miles (400 kilometers) above Earth.

A microscopic predator may offer a new way to protect some of the Caribbean's most endangered corals. Georgia Tech researchers found that tiny predatory bacteria can halt the spread of a destructive coral disease by hunting and consuming pathogens responsible for the infection.

The interaction between X-rays and matter can be actively controlled, according to an international research team led by the University of Hamburg and SLAC National Accelerator Laboratory that has succeeded in producing bright X-ray images with significantly less damage. In an ar
