Preservation of Isolated Vesicles in Submarine Pumice and Implications for Submarine Slope Stability

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Pumice clasts from submarine eruptions contain abundant isolated vesicles that are completely encased in glass. As erupted clasts cool, gas inside isolated vesicles contracts, leading to low pressures inside those vesicles. Despite low pressures, isolated vesicles can be preserved in submarine pumice deposits to water depths of approximately 1–

Mechanistic Diversity in Photoexcited Radical Redox Chemistry: A Critical Evaluation

Angewandte Chemie International Edition, Volume 65, Issue 42, 12 October 2026.
Many high‐profile examples of photoredox catalysis are proposed to proceed via excitation of an open‐shell intermediate form of the catalyst. However, there is much debate over whether such mechanisms are realistic and, if so, exactly how they can occur.
