No News Is Good News Testing Modality and Redundancy in Immersive Augmented Reality

open access: yesJournal of Computer Assisted Learning, Volume 42, Issue 1, February 2026.
ABSTRACT Background The modality and redundancy principles are well‐established within the cognitive theory of multimedia learning for their effectiveness in traditional media. However, previous studies applying these principles in virtual reality have shown contradictory results when immersive technologies are involved.

Distinct Cloud‐to‐Ground Lightning Properties in Frontal Versus Warm‐Sector Heavy Rainfall Events

open access: yesEarth and Space Science, Volume 13, Issue 2, February 2026.
Abstract Do systematic differences in cloud‐to‐ground (CG) lightning properties—particularly return stroke number and current intensity—exist across different thunderstorm types? This question is foundational not only to the atmospheric electricity but also to advancing lightning risk prediction, which crucially depends on a robust understanding of how

DeepRec: Global Terrestrial Water Storage Reconstruction Since 1941 Using Spatiotemporal‐Aware Deep Learning Model

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract Terrestrial water storage (TWS) plays an important role in describing the Earth system, as water availability is decisive for ecosystems and human development. Since 2002, the Gravity Recovery and Climate Experiment (GRACE) and its Follow‐On (GRACE‐FO) mission have measured TWS anomalies with unprecedented accuracy, enabling a leap in ...
