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

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

Unusual metal oxide shows signs of magnetism under lattice strain in ultrathin layers and more — today's student signal.

Ruthenium dioxide (RuO2) is a metal oxide that commonly serves as an important metallic conductor, quantum material and industrial electrocatalyst. While there have been debates surrounding the magnetic properties of RuO2, it is generally thought to be nonmagnetic in its bulk for

Global warming appears to have shifted into a faster gear. After removing the effects of El Niño, volcanic eruptions, and solar cycles, researchers found that the planet has warmed at roughly 0.35°C per decade over the past ten years, compared with just under 0.2°C per decade fro

Ant parenting may have evolved from the same brain systems that once controlled hunger. Researchers found that two chemical signals push clonal raider ants toward either caring for larvae or leaving to forage, with the balance changing as the ants grow older. Similar signals are

Xenophagocytosis is a natural immune process that limits interspecies organ generation by eliminating living donor cells, researchers at the Institute of Science Tokyo, Japan, report. By uncovering how embryonic macrophages eliminate living donor cells, the researchers developed

Strengthening El Nino 'adding fuel to a planet already on fire': UN chief and more — today's student signal.

A strengthening El Niño that could shatter all-time records is "adding fuel to a planet already on fire" and pushing the world into "uncharted territory," U.N. Secretary-General Antonio Guterres warned Friday.

Finding water on the moon may only be a matter of detecting the right vibrations.

With no background in coding, Faith Maeba, a psychology major, was reluctant when her mother first suggested she enroll in classes on artificial intelligence.

New research is giving children a voice in understanding how technological interruptions affect parent-child relationships. A paper, "Distracted, Interrupted, or Disrupted: A Pathway Model of Technoference," led by Associate Professor Cara Swit from Te Whare Wānanga o Waitaha | U

The signals that cells use to switch genes on have remained almost unchanged across 2 billion years of evolution, but the ones used to switch genes off vary dramatically from one branch of life to another, according to a new study from the Center for Genomic Regulation (CRG) in B

South Korea registered its highest temperature since records began more than a century ago on Sunday, as authorities warned people to "immediately" stop all outdoor activities in affected areas.

For the first time in more than a century, a total solar eclipse is coming to mainland Spain with an even longer encore next summer.

A study published in the Journal of Statistical Mechanics: Theory and Experiment (JSTAT), inspired by the behavior of bacterial colonies observed in previous experiments, uses mathematical models to describe the expansion of competing populations. The aim is to understand which f

Freeman Hrabowski Scholar Bianca Jones Marlin studies how caregiving takes shape in the brain and how some biological adaptations are passed to the next generation.

Fertilization is often imagined as a frantic race, with millions of sperm competing for a single prize. But new research by a team of evolutionary biologists from Syracuse University, the University of Siena in Italy and the University of Szeged in Hungary reveals a more surprisi

New York University researchers have pinpointed the molecular players responsible for plants "feeling full" once they've taken up enough nitrogen—a finding that could help scientists develop plants that absorb more nitrogen from the soil and allow farmers to reduce environmentall

Approximately 40% of insect species worldwide are thought to be in decline and under threat of extinction. Among the key causes are habitat loss, pollution and climate change. Another threat is artificial light from sources like streetlights and security lamps. In new research pu
