Discovery of sexual dimorphism of the laryngeal sac in the common minke whale Balaenoptera acutorostrata

open access: yesThe Anatomical Record, Volume 309, Issue 2, Page 397-416, February 2026.
Abstract Mysticetes, or baleen whales, have an air sac on the ventral surface of the larynx known as the “laryngeal sac.” The primary hypothesis regarding this structure's function is that it is involved in sound production. However, several other functions have been proposed, including air recycling, air storage, and even buoyancy control.

Mechanical Cues Regulate Estrogen and Progesterone‐Induced Nascent ECM Deposition by Human Endometrial Stromal Fibroblasts

open access: yesJournal of Biomedical Materials Research Part A, Volume 114, Issue 2, February 2026.
ABSTRACT The endometrium, the mucosal lining of the uterus, is a highly regenerative tissue that undergoes cyclic remodeling guided by tightly regulated levels of estrogen and progesterone. Stromal cells, including fibroblasts, are embedded within the connective tissue of the endometrium and contribute to the rapidly changing extracellular matrix (ECM).

Hydrologic Variability Drives Differential Methane Dynamics in Agricultural Reservoirs of the Northern Great Plains

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 2, February 2026.
Abstract Climate variability can regulate aquatic methane fluxes as increasing temperatures can elevate microbial metabolic rates, including methanogenesis. It is less well known how climate‐induced variability in seasonal precipitation and runoff might affect methane concentrations and fluxes in aquatic ecosystems.
