Microbial Controls on Dissolved Organic Nitrogen Cycling During Long‐Term Degradation Experiments

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Dissolved organic nitrogen (DON) is critical for marine microbial growth by providing carbon and nitrogen. Although DON is rapidly cycled, some compounds within this pool can persist for long‐periods of time. To better understand how DON is cycled by marine microorganisms, we conducted 548‐day incubations using surface‐derived dissolved ...

High resolution data reveal fundamental steps and turns in animal movements

open access: yesEcological Monographs, Volume 96, Issue 2, May 2026.
Abstract Animal movement paths display substantial complexity and variability, promoting efforts to identify universal rules and models that best describe them. Using high‐resolution (≥10 Hz) movement from 43 vertebrate species spanning diverse taxa, body sizes, and lifestyles, we show that paths are universally composed of straight‐line steps ...

Structure‐guided optimization of SLY1 expression and purification in Escherichia coli

open access: yesProtein Science, Volume 35, Issue 5, May 2026.
Abstract The SCFSLY1 ubiquitin ligase complex is a key regulator of gibberellin signaling, mediating the degradation of DELLA proteins through targeted ubiquitination. To enable detailed biochemical and structural studies of this complex, efficient recombinant production of SLY1 and its adaptor ASK1 is essential.

Quantifying and Mapping Regional C, N and P Stocks From Temperate Fens, Bogs, and Forested Peatlands Using Detailed Peat Bathymetry

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 4, April 2026.
Abstract Peatlands are known to store significant amounts of carbon (C), nitrogen (N) and phosphorus (P) globally. At the regional level, however, C stocks are often poorly assessed as peat depth variability within and among different types of individual peatlands is often ignored, and nutrient stock assessments are rare or based on limited ...

Caffeine-inducible gene switches controlling experimental diabetes

open access: yesNature Communications, 2018
Control of transgene expression should ideally be easy and with minimal side effects. Here the authors present a synthetic biology-based approach in which the caffeine in coffee regulates a genetic circuit controlling glucagon-like peptide 1 expression ...

Bridging the Gap From Peat to Ponds: Terrestrial and Aquatic Greenhouse Gas Emissions in an Evolving Permafrost‐Associated Subarctic Peatland

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 4, April 2026.
Abstract Rapid permafrost thaw in peatlands transforms the subarctic landscape into a mosaic of ponds and peat soil, varying in moisture, carbon and nutrients, and time since thaw. As subarctic permafrost degrades, ponds emerge and mature and can gradually infill with Sphagnum peat.

Mini-P-gp and P-gp Co-Expression in Brown Trout Erythrocytes: A Prospective Blood Biomarker of Aquatic Pollution

open access: yesDiagnostics, 2015
In aquatic organisms, such as fish, blood is continually exposed to aquatic contaminants. Multidrug Resistance (MDR) proteins are ubiquitous detoxification membrane pumps, which recognize various xenobiotics.
