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 Analysis," the research team led by Prof. Dr.-Ing. Kristina Schaaff, Dr. Valerie Hekkel and Quintus Stierstorfer analyzed anonymized usage data from approximately 77,000 IU online students who were using the Learning Companion Syntea at the time of the study.

Sensor-embedded 3D-printed repairs could help preserve ancient pottery

KoΓ§ University researchers have developed a conservation method that combines photogrammetry, digital modeling, 3D printing and embedded sensors to replace missing sections of archaeological amphorae. The customized fills can also monitor environmental and physical changes affecting the artifacts, offering a systematic approach to their conservation and long-term preservation.

From research to policy: Study turns EU wildfire assessments into a tool for better governance

Climate change, land-use change and socioeconomic pressures are turning wildfires from a primarily ecological process into a complex, systemic risk that cuts across ecosystems, infrastructure, public health, water resources, cultural heritage and rural livelihoods. Despite substantial investments in firefighting capacity, wildfires are projected to become more frequent, extreme and devastating, underscoring the need for cross-cutting solutions.

Ancient Rome's food shortages were shaped more by logistics than climate

Ancient Rome's greatest threat to food security wasn't the weather but the challenge of getting grain to the capital, according to a new study. By comparing hundreds of years of historical records with reconstructions of past climate, researchers found that periods of unusual heat, cold, drought or heavy rainfall rarely lined up with reported food shortages.

Students are anxiousβ€”and it's no surprise, since we are teaching them to be that way

Temporary anxiety can often surface before the first day of school. Sometimes, that can help kids get in the right mindset for a big day. But when anxiety becomes a constant feature of children's and teenagers' days, that stress doesn't switch off when they leave the classroom or finish an exam. It can become the body's norm, staying with learners long after graduation.

Ancient Chinese seeds spanning 5,000 years train AI to ease archaeology's specialist bottleneck

Ancient plant seeds provide important archaeological evidence for studying the evolution of human civilization. Lingnan University and Shandong University have jointly developed the world's first artificial intelligence (AI) archaeological system dedicated to identifying ancient Chinese plant seeds. The system emulates the identification process of archaeobotanical experts and achieves a classification accuracy of more than 90%.
