For the first time, researchers have mapped how the boundaries of magnetic nanostructures behave on extremely short timescales. The work of physicist Johan Mentink of Radboud University shows that these boundaries are much more stable than previously thought. This insight will aid the development of future ultra-fast and compact data storage.

A 2025 AI in Education trend report found that 90% of college students use AI in their coursework, with nearly half using it during the drafting process.
