Dispersion Analysis of Silver Thiogallate in a Broad Mid‐Infrared Range

open access: yesAdvanced Photonics Research, Volume 7, Issue 1, January 2026.
This study presents precise refractive index measurements of AgGaS2 crystal in the extended mid‐infrared region. Corrected Sellmeier equations are introduced, broadening the use of silver thiogallate for nonlinear frequency‐conversion. The results enable accurate modeling of nonlinear‐optical processes and facilitate further development and ...

Detectable Human Influence on Reduced Day‐to‐Day Temperature Variability in the Cold Season Driven by Arctic Sea‐Ice Loss

open access: yesAtmospheric Science Letters, Volume 27, Issue 1, January 2026.
Over recent decades, day‐to‐day temperature variability at Northern Hemisphere mid and high latitudes has decreased, especially in the autumn and winter seasons. It is unclear how much the observed reduction is driven by human‐caused global warming. Our study utilizes a novel machine‐learning detection tool to demonstrate that the reduction since the ...

Specialized Feeding Behavior of an Endangered Primate Enhances Forest Health in China

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
The endangered black‐and‐white snub‐nosed monkey (Rhinopithecus bieti) exhibits a specialized diet on the lichen Usnea longissima. We proved that the U. longissima is harmful to trees and the monkey mitigates overgrowth of the lichen, as well as promotes its regeneration to maintain population, thereby promoting ecosystem health and resilience.
