On-farm hatching and contact with adult hen post hatch induce sex-dependent effects on performance and welfare in broiler chickens

This study evaluates the effects of on-farm hatching and hen contact on broiler chicken performance and welfare, finding sex-dependent impacts on body weight and robustness.

A specific mesh-like organization of human septin octameric complex drives membrane reshaping and curvature sensitivity

The paper investigates the organization and function of human septin octameric complexes at membranes, finding they form a mesh-like structure that drives membrane curvature sensitivity and reshaping.

Polymerization cycle of actin homolog MreB from a Gram-positive bacterium

This study reports the first observation of organized MreB filaments and 3D structure from a Gram-positive bacterium, revealing unique polymerization mechanisms distinct from eukaryotic actin.

Direct observation of the conformational states of formin mDia1 at actin filament barbed ends and along the filament.

This study uses electron microscopy to directly observe two conformations of mDia1 FH2 domains interacting with actin filament barbed ends, supporting the stair stepping model.

Landscape connectivity alters the evolution of density-dependent dispersal during pushed range expansions

The paper examines how landscape connectivity affects phenotypic evolution during range expansions, finding that high connectivity can alter density-dependent dispersal, potentially slowing or reversing the transition from pushed to pulled dynamics.

Insights into animal septins using recombinant human septin octamers with distinct SEPT9 isoforms

This study isolates recombinant human septin octamers with distinct SEPT9 isoforms and shows they form filament assemblies and bind actin filaments.

Training level reveals a dynamic dialogue between stress and memory systems in birds

This study shows chronic stress affects spatial memory in birds depending on training level and emotional state, but not cue-based memory.

Membrane binding controls ordered self-assembly of animal septins

This study shows membrane binding enables fly septins to form ordered filamentous arrays, with C-terminal regions required for stacking.

Shifts from pulled to pushed range expansions caused by reduction of landscape connectivity

This study shows that reducing landscape connectivity can shift range expansions from pulled to pushed dynamics in parasitoid wasps, affecting genetic diversity and expansion speed.

Myosin 1b Flattens and Prunes Branched Actin Filaments.

This paper shows myosin 1b flattens and breaks Arp2/3-dependent actin branches and reduces new branch formation using in vitro assays and TIRF microscopy.

Human ESCRT-III Polymers Assemble on Positively Curved Membranes and Induce Helical Membrane Tube Formation

This study investigates how ESCRT-III proteins assemble on curved membranes and induce helical tube formation using in vitro experiments and imaging techniques.

Hidden Rice Diversity in the Guianas

This study identifies 50 rice varieties cultivated by Maroons in the Guianas, 15 of which are new, revealing hidden genetic diversity maintained through cultural practices despite external pressures.

Adhesion to nanofibers drives cell membrane remodeling through 1D wetting

This study identifies a novel physical mechanism, 1D wetting, by which Neisseria meningitidis drives plasma membrane remodeling on nanofibers independent of F-actin.

Ezrin enrichment on curved membranes requires a specific conformation or interaction with a curvature-sensitive partner

This study investigates how ezrin enrichment on curved membranes depends on its conformation or interaction with curvature-sensitive partners, showing that specific conformations and binding to I-BAR-domain proteins enable targeting to curved membranes.
