Measuring Temporal Variations of Nucleotide Pools in Microbial Granular Biofilm

open access: yesHelvetica Chimica Acta, EarlyView.
The developed metabolomics workflow enables quantification of energy nucleotides in complex microbial biofilms. The method provides a foundation for investigating rapid metabolic responses to dynamic environmental conditions. ABSTRACT Microbial communities often face environmental fluctuations that occur on timescales much shorter than their growth ...

Living on the edge: Habitat characteristics of northern myotis at the periphery of its distribution

open access: yesThe Journal of Wildlife Management, EarlyView.
Northern myotis selected tall trees with minimal decay, in patches with other roosting options. In our study area, these trees occurred in narrow bands within an agricultural matrix, differing from contiguous forest at the core of the species' distribution. Nevertheless, bats selected the tallest trees in the densest patches available.

Home and away: allometry and climate drive morphology of European rabbits in their native and introduced range

open access: yesOikos, EarlyView.
Climatic conditions shape phenotypic evolution by driving adaptations that optimise organismal function. Invasive species provide valuable systems to study these processes, as they often encounter novel climatic conditions in their introduced ranges. The European rabbit Oryctolagus cuniculus, native to the Iberian Peninsula, has established populations

The Long Trajectory of Rubber Physics: 3500+ Years and Counting

open access: yesJournal of Polymer Science, EarlyView.
Natural rubber's trajectory is traced from Mesoamerican use of Castilla elastica through vulcanization and the pneumatic tire to macromolecular physics and modern solid‐state refrigeration. Illustrations of C. elastica and an H. brasiliensis plantation frame the historical progression from indigenous material, then industrial crop and on to advanced ...

Botanic and heritage gardens as living laboratories in the age of the polycrisis

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Societal Impact Statement Cities face intertwined crises of climate, biodiversity loss and social disconnection. We show how botanic and heritage gardens can help address these challenges as living laboratories to generate place‐based evidence and public engagement.

Validation of a novel bioassay method for the evaluation of the activity of slow‐acting insecticides on tomato borer Phthorimaea absoluta

open access: yesPest Management Science, EarlyView.
Extended bioassays revealed that azadirachtin and spirotetramat show strong delayed effects against Phthorimaea absoluta, underestimated by the standard Insecticide Resistance Action Committee (IRAC) method 022 protocol. Incorporating long‐term exposures is essential to accurately assess slow‐acting insecticides and improve resistance management ...

Analysis of piston oscillation cooling characteristics of OP2S engine piston

open access: yesCase Studies in Thermal Engineering
The Opposed-Piston Two-Stroke (OP2S) engine is renowned for its high power density and significant thermal load, necessitating the incorporation of an internal cooling oil chamber within the piston to facilitate forced cooling.

Photochemical fluorescence activation in arrays of microspherical containers

open access: yesResponsive Materials, EarlyView.
Photoresponsive microdroplets can be produced with precise structural control from organic solutions of a photoactivatable fluorophore and aqueous solutions of a surfactant at a microfluidic cross junction. These dye‐doped microspheres assemble spontaneously in close‐packed arrays in aqueous media.
