Altered Phenotypic Responses of Asexual Arctic Daphnia After 10 Years of Rapid Climate Change

open access: yesGlobal Change Biology, Volume 31, Issue 3, March 2025.
Freshwater ecosystems in the Arctic are important sentinels for climate change, but not much is known about the potential for rapid adaptation of their asexually reproducing key zooplankton member. We compared thermal and hypoxia tolerance of resurrected dormant stages of Daphnia from an Arctic meromictic lake to that of their modern descendants.

In Bio‐Based Self‐Healing Concrete: Effect of Nutrient Components of the Media on Mechanical Properties and Environmentally Friendly Concrete Development

open access: yesAdvances in Civil Engineering, Volume 2025, Issue 1, 2025.
More durable and eco‐friendly alternatives to concrete are needed to meet the growing global demand for this material. About 7% of all human‐caused CO2 emissions come from cement production. Integrating bacteria into concrete can prolong its lifespan, improve durability, and promote the sustainability of the concrete.

Filaments for 3D Printing of Iridescent Structural Colors

open access: yesAdvanced Optical Materials, Volume 12, Issue 34, December 3, 2024.
Structural colors are a sustainable alternative to conventional colorants, due to their longevity and flamboyant appearance. Inspired by nature, it is presented a scalable strategy to prepare polymeric filaments with iridescent‐shimmering structural color.

Constitutive Androstane Receptor Regulates Germ Cell Homeostasis, Sperm Quality, and Male Fertility via Akt‐Foxo1 Pathway

open access: yesAdvanced Science, Volume 11, Issue 43, November 20, 2024.
This study highlights the role of the constitutive androstane receptor (Car), a receptor of endo and xeno‐biotics, in testicular pathophysiology. The results indicate that Car inhibition impaired male fertility due to altered sperm quality, specifically histone retention, which is correlated with offspring's survival. This work demonstrates that Car is

Structural Colors Derived from the Combination of Core–Shell Particles with Cellulose

open access: yesAdvanced Photonics Research, Volume 5, Issue 10, October 2024.
The melt‐shear organization technique uses tailor‐made core–shell particles to produce opal films with structural colors. Cellulose is incorporated into these films to improve the wetting behavior and the films’ mechanical properties while maintaining the composites’ structural color.

Pig manure degradation and carbon emission: Measuring and modeling combined aerobic–anaerobic transformations

open access: yesJournal of Environmental Quality, Volume 53, Issue 5, Page 589-603, September/October 2024.
Abstract Greenhouse gas emissions from liquid livestock manure storage significantly contribute to global warming. Accurate farm‐scale models are essential for predicting these emissions and evaluating manure management strategies, but they rely on multiple parameters describing carbon loss dynamics.

Soft Synthetic Cells with Mobile Membrane Ligands for Ex Vivo Expansion of Therapy‐Relevant T Cell Phenotypes

open access: yesSmall, Volume 20, Issue 37, September 12, 2024.
This study introduces a novel synthetic cell technology utilizing dispersed liquid–liquid phase‐separated droplet‐supported lipid bilayers for ex vivo T cell expansion. By incorporating mobile ligands on soft synthetic cells, the technology enhances the expansion of regulatory CD8+ T cells with reduced immune suppression susceptibility.

Spirotetramat reduces fitness of the spotted‐wing Drosophila, Drosophila suzukii

open access: yesInsect Science, Volume 31, Issue 4, Page 1222-1230, August 2024.
Oral take up of spirotetramat by Drosophila suzukii females inhibits the activity of acetyl‐CoA decarboxylase (ACC) that is needed for fecundity and desiccation resitance. Abstract With climate change, the spotted‐wing Drosophila (SWD, Drosophila suzukii) invades a great number of fruit production regions worldwide. A plethora of insecticides are being

Phenotypic and genetic divergence in a cold‐adapted grasshopper may lead to lineage‐specific responses to rapid climate change

open access: yesDiversity and Distributions, Volume 30, Issue 6, June 2024.
Abstract Aim Species responses to global warming will depend on intraspecific diversity, yet studies of factors governing biogeographic patterns of variability are scarce. Here, we investigate the evolutionary processes underlying genetic and phenotypic diversity in the flightless and cold‐adapted grasshopper Sigaus piliferus, and project its suitable ...

Mass Spectrometry of Putrescine, Spermidine, and Spermine Covalently Attached to Francisella tularensis Universal Stress Protein and Bovine Albumin

open access: yesBiochemistry Research International, Volume 2024, Issue 1, 2024.
Bacterial and mammalian cells are rich in putrescine, spermidine, and spermine. Polyamines are required for optimum fitness, but the biological function of these small aliphatic compounds has only been partially revealed. Known functions of polyamines include interaction with nucleic acids that alters gene expression and with proteins that modulate ...
