Crystal structure of human NIF3‐like protein reveals dynamic hexameric assembly with a single divalent metal binding site

open access: yesThe FEBS Journal, EarlyView.
We present the first crystal structures of human NIF3, revealing a dynamic, hexameric ring with a central cavity regulated by flexible insertion domains. Crucially, human NIF3 features a mononuclear zinc‐binding site, marking a distinct evolutionary departure from the dinuclear centers of bacterial homologs.

Influence of Illumination Conditions and Cross‐Polarization on DSLR‐Based Clinical Tooth Color Assessment: A Comparison With Spectrophotometric Measurements

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Aim To evaluate the influence of different illumination systems and cross‐polarization on tooth color determination using DSLR photography, and to assess the agreement between photographic methods and spectrophotometric measurements. Materials and Methods Thirty‐one participants (62 maxillary central incisors) were included. Color measurements

Thermogenesis‐derived spatiotemporal microclimates guide pollinator movement to ensure pollination

open access: yesJournal of Integrative Plant Biology, EarlyView.
Alocasia odora's microclimatic heterogeneity guides Colocasiomyia fly movement within its inflorescence. During the female stage, midday heat in the upper spadix pushes flies down to the cooler female zone. During the male stage, nocturnal warmth in the upper part pulls flies upward and spathe constriction closes the lower female chamber.

CryoFluorSEM – A new approach for fluorescence and EM imaging of cryofractured plant samples

open access: yesJournal of Microscopy, EarlyView.
Abstract Cryo‐scanning electron microscopy (CryoSEM) permits the preparation and detailed imaging of bulky samples while keeping them in a hydrated state. For plant biology, cryofractures give information on cell ultrastructure and tissue organisation within a much larger context that is the whole organ or organism.

Cyclin‐dependent kinase 13 is indispensable for normal mouse heart development

open access: yesJournal of Anatomy, Volume 246, Issue 4, Page 616-630, April 2025.
Congenital heart disease (CHD) is the most common defect in live births. The role of cyclin‐dependent kinase (CDK13) in cardiogenesis and CHD was studied using a transgenic mouse model (Cdk13tm1b) carrying deletion of exons 3 and 4, causing loss of function.

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
