Physiological roles of lignins – tuning cell wall hygroscopy and biomechanics

open access: yesNew Phytologist, Volume 248, Issue 6, Page 2674-2706, December 2025.
Summary Lignins constitute the second most abundant carbon‐storing biopolymers in the biosphere. These phenolic polymers accumulate in different concentrations, compositions, and localisations within and between cell wall layers and cell types. Lignins were acquired during plant terrestrialisation 450 million years ago, and the diversification of their

Biomass production of tropical trees across space and time: The shifting roles of diameter growth and wood density

open access: yesJournal of Ecology, Volume 113, Issue 11, Page 3141-3158, November 2025.
Diameter growth is an important and good indicator of forest carbon production. However, size‐related changes in wood density, which are usually neglected, are critical for accurate short‐ and long‐term carbon assessments, especially in tropical humid sites.

Growth–survival trade‐off in temperate trees is weak and restricted to late‐successional stages

open access: yesJournal of Ecology, Volume 113, Issue 11, Page 3466-3477, November 2025.
Our findings highlight a role of disturbances in filtering life‐history strategies and their potential impact on forest dynamics and global carbon cycling, but also a need to better understand the mediating processes of tree demographic trade‐offs.

Physiological Control of Realheart Total Artificial Heart

open access: yesArtificial Organs, Volume 49, Issue 10, Page 1548-1557, October 2025.
This study evaluates the Realheart Total Artificial Heart's preload‐based physiological controller, which dynamically adjusts heart rate and stroke volume to mimic the heart's natural responses during sleep, rest, and exercise using a hybrid mock circulation loop of the cardiovascular system.

Warming strengthens food web effects of predator phenotypic variation

open access: yesFunctional Ecology, Volume 39, Issue 9, Page 2284-2299, September 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Intraspecific variation modifies ecological processes and ecosystem functioning. Still, we know relatively little of how the nature and strength of ecosystem effects caused by intraspecific variation may interact with climate change.

Very High Cycle Fatigue Performance of Ductile Cast Iron With Different Microstructures

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 9, Page 3950-3966, September 2025.
ABSTRACT The very high cycle fatigue performance of four ductile cast irons, a solid solution strengthened ferritic, ferritic‐pearlitic, and two austempered ductile cast irons, was investigated by ultrasonic fatigue testing under fully reversed loading conditions. The step‐stress fatigue testing method incorporating re‐use of runouts was employed, with

Hochdrucksynthese kristalliner doppelschichtiger Kohlenstoffnitrid‐Netzwerke stabilisiert in Bi7C10N18(N3(1‐x)O3x)

open access: yesAngewandte Chemie, Volume 137, Issue 35, August 25, 2025.
High‐pressure chemical reaction between Bi and various hydrogen‐free C‐N precursors induced by the infrared laser heating in a diamond anvil cell, leads to the formation of a compound Bi7C10N18(N3(1‐x)O3x), featuring double layers of poly‐N‐(1,3,5‐triazin‐2‐yl)‐guanidine [C4N6x‐]n and non‐polymerized guanidinate anions CN35‐.

Acid Sulfate Soils and Their Pathways of Impact: A Swedish Case Study

open access: yesEcology and Evolution, Volume 15, Issue 7, July 2025.
This study is an initial report on the situation in an estuary affected by acidic sulfate soils in an area of Sweden where this has not been investigated before. The study clearly states that metals and acidic effluents from the agricultural acidic sulfate soil are transported via riverine water to the adjacent estuary where metals accumulate in the ...
