Seeing herbaria in a new light: leaf reflectance spectroscopy unlocks trait and classification modeling in plant biodiversity collections

open access: yesNew Phytologist, Volume 251, Issue 2, Page 811-829, July 2026.
Summary Reflectance spectroscopy is a rapid method for estimating traits and discriminating species. Spectral libraries from herbarium specimens represent an untapped resource for generating broad phenomic datasets across space, time, and taxa. We conducted a proof‐of‐concept study using trait data and spectra from herbarium specimens up to 179 yr old,

First Observation of the Second Harmonic of Upper Band Chorus Waves Linking to Slow Z‐Mode

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The Z‐mode, comprising fast and slow branches, is a ubiquitous electromagnetic wave in planetary magnetospheres. While fast Z‐mode generation is attributed to electron cyclotron maser instability, the slow Z‐mode mechanism remains unresolved.

Complex Shallow Unilateral Rupture of the 2025 Mw 7.0 Hubbard Glacier Earthquake Terminated by a Restraining Bend on the Connector Fault

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Despite decades of study, the detailed geometry of the Connector fault at the Alaska–Canada border remains poorly constrained. We investigate the rupture complexity and directivity of the 6 December 2025, Mw 7.0 Hubbard Glacier earthquake using hypocenter relocations, moment tensor inversions of the mainshock and aftershocks, and finite‐fault ...

Brillouin Zone Folding‐Driven Topological Band Flips Based on BICs via Twisted Photonic Crystals

open access: yesNanophotonics, Volume 15, Issue 11, 13 June 2026.
Brillouin zone folding (BZF)‐driven topological band flips are demonstrated via twisted photonic crystals (PhCs) incorporating bound states in the continuum (BICs). Twist perturbation generates three new bands, each linked to either a BIC or a guided‐mode resonance (GMR).

Numerical Modeling of Tank Cars Carrying Hazardous Materials With and Without Composite Metal Foam

open access: yesAdvanced Engineering Materials, Volume 28, Issue 11, 3 June 2026.
Large‐scale puncture models consisting of hazardous materials (HAZMATs) tank car with protective steel–steel composite metal foam (S–S CMF) are solved numerically. Tank car plate with added 10.91–13.33 mm thick S–S CMF layer does not puncture. Protective S–S CMF absorbs impact energy, reduces plate deformation, and prevents shear bands formation ...
