At colleges, the AI boom means everyone wants to dabble in computer science
With no background in coding, Faith Maeba, a psychology major, was reluctant when her mother first suggested she enroll in classes on artificial intelligence.

How digital interferences shape parent-child time
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 |
Life speaks one universal language to activate genes: It speaks many more to silence them
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
South Korea records its highest-ever temperature of 42.5 C
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.
August's total solar eclipse will sweep over Spain, Iceland and Greenland
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.
How fitness, speed and position shape competition in expanding populations
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
Rideshare launches boost regional GDP and flexible jobs, study finds
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
Mom or not, caring for babies changes the brain
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.
A cooperative approach to reproductive success
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
Newly unearthed mechanism that helps plants 'feel full' could help crops use fertilizer more efficiently
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
How simple amber lights could make nights safer for insects
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
Climate change could dramatically reduce water flowing from the West's headwaters
The small mountain streams that feed many of the West's rivers may face a much drier future. A new study led by NAU researchers found that groundwater-fed streamflow, known as base flow, has been steadily declining across headwater watersheds in the western United States since
New microscopy method achieves angstrom-scale localization precision with one laser
Researchers in the lab of Sam Peng, the Pfizer Inc.–Gerald Laubach Career Development Assistant Professor of Chemistry at MIT and a core institute member of the Broad Institute of MIT and Harvard, have developed a super-resolution imaging technology. It allows scientists to
Antibiotic resistance is spreading through South Africa's water systems. This study explains how
Antimicrobial resistance (AMR) is defined as the ability of disease-causing microorganisms to withstand treatments like antibiotics.
Webb reveals warped structure in nearby TW Hydrae's protoplanetary disk
Using the James Webb Space Telescope (JWST), astronomers obtained high-contrast coronagraphic images of the protoplanetary disk around the young, nearby star TW Hydrae. Results of the observational campaign, published July 27 on the preprint server arXiv, shed more light on the
Supergene solves evolutionary puzzle of mirror-image flowers
The left-right asymmetry of South African butterfly lilies (genus Wachendorfia) has been regarded as a classic evolutionary puzzle for more than a century. Due to the mirror-image arrangement of the floral parts, the plants achieve efficient cross-pollination. The molecular
Why some nitrogen-processing enzymes are more efficient than others
Nitrogen gas is abundant in Earth's atmosphere, but most living organisms can't readily use it. Only a subset of microbes with enzymes known as nitrogenases can break nitrogen gas apart and convert it into ammonia.
Laid to rest with care: Ancient infants, perhaps twins, found in 1,200-year-old latrine
More than 1,000 years ago, two babies were tucked away in an abandoned Roman toilet channel. Yet, despite what the location suggests, they were cherished, not discarded.
AI use mirrors student schedules in study of 77,000 online learners
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
Forever chemicals and pesticides under Trump: what to know
Since returning to power, President Donald Trump's administration has approved five pesticides considered by many to be PFAS "forever chemicals," a class of toxic substances facing bans and increasing restrictions around the world.
Dark matter’s secret force does the opposite of what scientists expected
Dark matter particles may exert a hidden force on one another, but its effects are stranger than expected. An extra attraction helps the particles cluster, yet it also makes dark matter effectively lighter as the Universe expands. That weakens its gravitational impact and
Without this protein, damaged muscle turns to fat and scar tissue
A protein once thought to mainly protect chromosome ends may also be essential for keeping muscle stem cells ready to repair injuries. Researchers found that TRF2 helps these cells maintain their identity and coordinate the cycle of rest, repair, and renewal.
Mathematicians prove perfectly fair elections are impossible
Mathematicians have shown that no electoral system can perfectly balance local representation, proportional national results, and a fixed-size parliament once enough parties compete. A newly proposed voting method could soften these unavoidable trade-offs and produce outcomes
Smart sensor identifies present molecules by remembering the past
Most sensors are designed to do only one thing: detect what passes through them. But what if a sensor could do more? To create a new generation of technology, researchers have looked to living systems for inspiration. If a sensor could detect molecules, could it also remember
DESI side project reveals the spectra of disintegrated exoplanets
Using spectral data from the Dark Energy Spectroscopic Instrument (DESI), astronomers have gained some of the clearest evidence yet that white dwarf stars are accreting debris from disintegrating exoplanets. Captured while DESI was unable to study its primary targets: distant
Indigenous territory maintains ecological stability amid agricultural expansion in the Brazilian savanna
"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
