Airborne Observations Reveal Underestimated Riverine Methane Emissions Across the Amazon

open access: yesGeophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Strongly increasing trends in global methane in recent decades highlight the importance of understanding source‐sink attributions and climate feedback mechanisms, especially for large natural sources like wetlands. Here, we present an analysis of airborne methane observations above the Amazon Basin conducted from December 2022 through January ...

Exceptional Light Propagation via Generalized Bulk‐Edge Correspondence

open access: yesNanophotonics, Volume 15, Issue 13, 13 July 2026.
We show that unlike in electronic systems, localized edge states in topological photonics are governed not only by nontrivial bulk topology, but also by polarization‐dependent light‐line confinement conditions inherent to Maxwell's equations. This fundamentally generalized bulk‐edge correspondence unlocks new regimes of tunable near‐cutoff localization
