Taxonomic reassessment of fossil Sequoia and Protosequoia from the Upper Miocene of Central Honshu, Japan, with implications for leaf morphological variation in extant S. sempervirens

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Since its emergence in the Mesozoic, Sequoia (Cupressaceae) has been considered to possess conserved leaf morphology. However, recent studies have shown that the leaves of extant S. sempervirens become smaller, with a scale form, with increasing tree height.

Bending‐Induced Vibrational Landscape Reorganization Governs Energy Dissipation in Perylene Bisimides

open access: yesAngewandte Chemie, EarlyView.
Gradually bent perylene bisimides (PBIs) isolate structural distortion as the sole variable and exhibit negligible intersystem crossing, uncovering rapid vibrational dephasing as the dominant driver of internal conversion through excited‐state vibrational landscape reorganization.

Help‐Seeking and Substance Use Among Police Staff After the 2018 Strasbourg Christmas Market Attack

open access: yesAmerican Journal of Industrial Medicine, EarlyView.
ABSTRACT Background The use of mental health services by police staff is usually low. After the 2018 attack on the Strasbourg Christmas market, police officers exposed to psychotraumatic risks were found to have a higher PTSD risk. This study aims to describe the help‐seeking and substance use by police staff after the attack.

Mechanochemistry Meets Catalysis: Metal Complexes for Greener Organic Transformations

open access: yesAngewandte Chemie, EarlyView.
Mechanochemistry is redefining metal catalysis by controlling catalyst formulation, speciation, and deployment. This Review shows how milling, LAG, RAM, and TSE enable rapid metal‐complex assembly, distinctive catalytic manifolds, and scalable synthesis beyond solution chemistry.
