GenAI use among online adult learners associated with academic performance and technology confidence

University of Phoenix scholars have published research examining how nontraditional undergraduate students use generative artificial intelligence (GenAI) in online higher education. The study found that more frequent GenAI use was significantly associated with higher academic performance and stronger confidence in technology skills. Lower confidence in reading, writing and math, and greater time demands from work, study or family responsibilities, did not significantly predict use.

Astrophysicists use wave simulations to open a new window on dark matter

Astrophysicists from The University of Hong Kong (HKU), working with a research team led by Beijing Normal University (BNU), have developed a more physically realistic approach to testing how ultralight, or "fuzzy," dark matter could influence gravitationally lensed images. The study is the first to make gravitational-lensing predictions directly from three-dimensional wave simulations of fuzzy dark matter.

Biologists battle over North America's largest crayfish

When Caitlin Bloomer wrestled the massive Crawzilla crawdad—yes, that's its actual common name—out of the muck during a biological survey in Kentucky, she was convinced it was the largest crayfish ever recorded.

Scientists make progress in mapping chemicals to six groups of common diseases

Exposure to hazardous chemicals can contribute to noncommunicable diseases and remains a key public health challenge. Most chemicals used in consumer products, including food packaging, lack sufficient data to determine whether they are safe. Current testing approaches cannot effectively check for all possible health outcomes, and many testing requirements check only for genotoxicity and examine one substance at a time. Yet evidence shows that consumers are simultaneously exposed to complex mixtures of chemicals from many types of products.

Can this biotech innovation halt the destructive march of a cereal killer?

A UK-led research collaboration has taken a significant step in the global effort to protect cereal crops from the devastating blast fungus. Researchers at the John Innes Centre explored a recently discovered class of plant defense receptors, showing at the molecular level how they limit blast pathogen attacks and how they might be bioengineered to provide broader, more durable immunity in wheat, barley and rice.

Combined satellite views offer clues to magma movement beneath Ethiopia's volcanoes

Magma moving beneath a volcano can make the ground rise, sink or shift sideways. Measuring these changes gives scientists clues about where magma is stored and how it travels. A study published in Geodesy and Geodynamics used satellite radar to examine the November 2025 eruption of Hayli Gubbi in Ethiopia's Afar Depression. Hayli Gubbi and nearby Erta Ale are separate volcanoes within the same volcanic zone, where three tectonic plates are pulling apart.

Bennu asteroid samples point to a surprising origin involving Jupiter

The asteroid Bennu orbits the sun once every 1.2 years and approaches Earth every six years, passing within around 300,000 kilometers. NASA took advantage of this to collect material from the celestial body. In a spectacular operation in 2023, the US space agency collected samples from the surface of the asteroid Bennu by its OSIRIS-REx probe.

Starch-based sensor changes color to indicate moisture in food packaging

Brazilian researchers have developed a biodegradable, starch-based sensor that changes color when moisture enters food packaging. With the addition of cobalt chloride, the sensor changes from blue to pink as moisture levels rise and back to blue as they fall. Consumers and manufacturers could use it to monitor the quality and crispness of foods such as cookies with the naked eye or a cellphone camera, without complex equipment.

Gene editing produces soybean with more than 90% oleic acid

Sejong University researchers have developed a high-quality soybean with improved oxidative stability, reduced saturated fat and increased seed fatty acid content. The research team led by Hyun Uk Kim, a professor in the Department of Bio-Industrial Resources Engineering at Sejong University, created the soybean line containing up to 90.2% oleic acid using CRISPR/Cas9 gene-editing technology. The study is published in the Plant Biotechnology Journal.
