FEBS Letters, EarlyView.An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Period–Luminosity–Metallicity–Color Relations of Late-type Contact Binaries in the Big Data Era
The Astrophysical JournalBinary stars ubiquitous throughout the Universe are important. Contact binaries (CBs) possessing period–luminosity (PL) relations could be adopted as distance tracers. The PL relations of CBs are influenced by metallicity abundance and color index, which

Linguistic Distances and Ethnolinguistic Fractionalization and Disenfranchisement Indices [PDF]
, 2016 Ruhlen (1994) reconstructed 27 words of the very first language. Some linguists raised eyebrows about the words themselves, but not so much about the idea that all our languages descend from one, or a very small number of, language(s).1 Today, most linguists think that the diversity of languages is the result of the migration ‘out of Africa’ of Homo ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration
FEBS Letters, EarlyView.Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Near Miss Detection Using Distancing Monitoring and Distance-Based Proximal Indicators
IEEE AccessDespite efforts to improve road safety, accidents persist due to insufficient evidence from manual police reporting, non-optimized detection algorithms, and technical limitations in real-time video processing and modelling.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis
FEBS Letters, EarlyView.Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

On the Geography of Trade: Distance is Alive and Well [PDF]
It has been widely argued that, with the decline in trade costs, the importance of distance has declined over time. On the other hand, most gravity models find that the importance of distance has increased over time.

Modelling stem cell differentiation related processes—A practical overview for biologists
FEBS Letters, EarlyView.Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Variables as stellar tracers and distance indicators [PDF]
, 2015 The importance of pulsating stars as stellar population tracers and primary distance indicators is briefly reviewed. In particular, we discuss several approaches based on the comparison between the predictions of nonlinear convective pulsation models and

Design and analysis strategies for robust microbiome ageing research
FEBS Letters, EarlyView.The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an
