Investigating correlations between translucency and wear resistance in lithium silicate-based dental glass-ceramics

open access: yesBoletín de la Sociedad Española de Cerámica y Vidrio
Lithium silicate-based glass-ceramics are widely employed dental materials, showing superior aesthetics (determined by translucency) but poorer wear resistance under severe contact conditions than alternative, artificial crown materials.

Resistance of Tectona grandis To Ceratocystis Wilt

open access: yesForest Pathology, Volume 56, Issue 2, April 2026.
ABSTRACT Tectona grandis (teak) is a tree species highly appreciated for its high‐quality hardwood and versatile industrial applications. Despite clonal teak plantations showing several advantages, such as reduced rotation time and increased wood volume production, the genetic uniformity of plantations makes them more susceptible to diseases ...

Canalized to heat, plastic to cold: adaptive coordination of leaf and seed strategies in populations spanning an elevational gradient

open access: yesNew Phytologist, Volume 250, Issue 2, Page 873-884, April 2026.
Summary In tropical mountains, surviving temperature extremes demands finely tuned strategies. We investigated how populations of the bromeliad Pitcairnia flammea across a 2200 m elevational gradient balance genetic canalization and plasticity, and whether thermal strategies are coordinated between seeds and leaves.
