Tech Xplore / New AI model accurately grades messy handwritten math answers and explains student errors
A research team affiliated with UNIST has unveiled a novel AI system capable of grading and providing detailed feedback on even the most untidy handwritten math answers—much like a human instructor.
Phys.org / The year's first meteor shower and supermoon clash in January skies
The year's first supermoon and meteor shower will sync up in January skies, but the light from one may dim the other.
Medical Xpress / A protein that makes hydrogen sulfide shows potential as a therapeutic target for Alzheimer's disease
Scientists at Johns Hopkins Medicine say results of a new study are advancing efforts to exploit a new target for Alzheimer's disease: a protein that manufactures an important gas in the brain.
Phys.org / What's inside Mexico's Popocatépetl volcano? Scientists obtain first 3D images
In the predawn darkness, a team of scientists climbs the slope of Mexico's Popocatépetl volcano, one of the world's most active and whose eruption could affect millions of people. Its mission: figure out what is happening ...
Phys.org / Image: JWST captures colliding spiral galaxies
Mid-infrared observations from NASA's James Webb Space Telescope, shown in white, gray, and red, are combined here with X-ray data from NASA's Chandra X-ray Observatory, highlighted in blue. Together, these different wavelengths ...
Phys.org / New dataset maps global city boundaries in high resolution from 2000 to 2022
A research team led by Prof. Liu Liangyun from the Aerospace Information Research Institute of the Chinese Academy of Sciences (AIRCAS) has produced the first comprehensive, high-resolution map of global city and town boundaries, ...
Phys.org / Climate policies can backfire by eroding 'green' values, study finds
A popular vision of life after climate action looks like vegetarians riding bikes, city centers without cars, and people foregoing air travel. But a new paper published in Nature Sustainability finds that climate policies ...
Phys.org / Ethylene and oxygen found to drive periderm regeneration after plant injury
Plants have an extraordinary ability to sense tissue damage and quickly rebuild their protective outer layers, a process vital for survival amid environmental stresses. The periderm—a specialized protective tissue found ...
Phys.org / 2025 was one of three hottest years on record, scientists say
Climate change worsened by human behavior made 2025 one of the three hottest years on record, scientists said.
Medical Xpress / Visual analog scale has comparable validity for perennial allergic, nonallergic rhinitis
The visual analog scale (VAS) demonstrates comparable validity for perennial allergic rhinitis (PAR) and nonallergic rhinitis (NAR) severity and quality-of-life (QoL) impairment, according to a study published online Dec. ...
Phys.org / Encoding adaptive intelligence in molecular matter by design
For more than 50 years, scientists have sought alternatives to silicon for building molecular electronics. The vision was elegant; the reality proved far more complex. Within a device, molecules behave not as orderly textbook ...
Medical Xpress / Loss of vitamin C synthesis protects animals from deadly schistosome infection
Scientists at Children's Medical Center Research Institute at UT Southwestern (CRI) have discovered a benefit of vitamin C deficiency: protection from a major parasitic disease. Their research suggests an explanation for ...
