Dissolved Black Carbon in North Cascades Snow, Meltwater and a Downstream River

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract Quantification of black carbon on snow in the Cascade Range is needed due to increasing wildfire intensity and frequency. Here, the benzenepolycarboxylic acid (BPCA) molecular method was used to measure dissolved black carbon (DBC) in snow, nearby rivers, streams, and supraglacial melt collected in 2022 and 2023 from Mount Baker and Mount ...

Monocyte Chemokines Enhance Atherosclerotic Plaque Necrosis After Bacterial Kidney Infection

open access: yesThe FASEB Journal, Volume 40, Issue 7, 15 April 2026.
Cardiovascular event rates rise after acute infections. After a single pyelonephritis episode in Ldlr−/− mice, atherosclerotic plaque necrotic core size increased, mediated by chemokine receptor CCR2‐induced monocyte mobilization from the bone marrow.

First Observations of Potential Iteroparity in Pacific Capelin Mallotus catervarius

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Using histology to examine ovarian structures in Pacific capelin for the first time, we found biological evidence that captive, age‐1, female Pacific capelin Mallotus catervarius are capable of iteroparity (41% of mature females). Evidence of the potential to spawn over multiple years included more than one oocyte cohort, including primary ...

Why we age

open access: yesBiological Reviews, Volume 101, Issue 2, Page 911-925, April 2026.
ABSTRACT Three categories of explanations exist for why we age: mechanistic theories, which omit reference to evolutionary forces; weakening force of selection theories, which posit that barriers exist that prevent evolutionary forces from optimising fitness in ageing; and optimisation theories, which posit that evolutionary forces actually select for ...
