Polygonal tepee structures of Arabia

The Depositional Record, Volume 12, Issue 1, February 2026.
Tepee structures on Sheybarah Island form polygonal microbial cemented crusts in the intertidal. Radiocarbon dating suggests they formed in the Holocene and reflect minor sea‐level changes, highlighting their value as palaeoenvironmental indicators. Satellite surveys identified 126 polygonal features, including coral reefs that may have developed on ...

Extensile Active Hydrogels Driven by Living FtsZ Polymers. [PDF]

Small
Upon post‐gelation activation with Mg2⁺/GTP, living FtsZ polymers treadmill inside a polyacrylamide network, generating extensile internal stresses that drive isotropic swelling and softening. Interpreting mechanics against a Flory–Rehner swelling baseline separates passive dilution from genuine activity, revealing an FR‐normalized permittivity that ...

The Generation and Control of Irregularly Shaped Perfect Vector Vortex Beams on Hybrid Poincaré Spheres Using All‐Dielectric Metasurfaces

Nanophotonics, Volume 15, Issue 3, 12 February 2026.
Based on an all‐dielectric metasurface with cross‐phase modulation, we achieve the generation and polarization control of integers and fractional order irregular perfect vector vortex beams on the hybrid Poincaré sphere, opening a new avenue for optical field manipulation.

Local species‐specific effect of trees and shrubs on the incidence of the millet head miner, Heliocheilus albipunctella (Lepidoptera, Noctuidae)

Agricultural and Forest Entomology, Volume 28, Issue 1, Page 38-48, February 2026.
Abstract Understanding the interactions between crop pests, natural enemies and semi‐natural habitats in agricultural landscapes is crucial for developing ecology‐based pest management in agroecosystems. In the present study, we investigated the local‐scale species‐specific effect of tree and shrub cover and diversity on the incidence and natural pest ...

Combined heat and drought affect the abundance, composition and diversity of subalpine surface‐active soil arthropod communities

Ecological Entomology, Volume 51, Issue 1, Page 98-112, February 2026.
We applied factorial soil warming and moisture reduction treatments directly in the field in the Australian subalpine to assess changes to surface‐active soil arthropod abundance, diversity and community composition. After identifying nearly 50,000 specimens to order, we found a stronger effect of sampling month than treatment.
