A University of Warwick-led analysis of almost 5,000 student-authored reports suggests that student writing has become more polished and formal since the introduction of ChatGPT in late 2022— but grades have remained stable.
Rising sea levels along coastlines not only threaten populations, but also pose a danger to agricultural crops, which may be damaged by surging amounts of saltwater. Researchers have, in response, sought to improve salt-tolerance in plants. An international team of scientists now reports the identification of cell traits that are critical to tolerating saltwater inundation—a finding that potentially offers new pathways for creating plants that can survive in harsh environments.
Researchers at Thomas Jefferson University have developed a groundbreaking automated machine learning (AutoML) model that can accurately differentiate between two common types of brain tumors using preoperative MRI scans, potentially improving surgical planning and patient outcomes.
The study, published in the December 2025 issue of Otolaryngology–Head and Neck Surgery, represents the first application of AutoML technology specifically trained to classify pituitary macroadenomas and parasellar meningiomas—two benign but challenging-to-distinguish brain tumors that require different treatment approaches.
