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 ...

Photographs of Stellar Spectra [PDF]
Nature, 1886 THE article upon this subject in NATURE, vol. xxxiv. p. 439, requires a correction which has been pointed out by Dr. Copeland. The spectrum of the star DM. + 37° 3821 was observed by him on September 22, 1884, and found to contain bright lines; the observation was published in the Monthly Notices for December 1884, but was overlooked at the time when ...

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Toward Robust Corrections for Stellar Contamination in JWST Exoplanet Transmission Spectra
The Astronomical JournalTransmission spectroscopy is still the preferred characterization technique for exoplanet atmospheres, although it presents unique challenges that translate into characterization bottlenecks when robust mitigation strategies are missing.

The Disentangling of Stellar Spectra [PDF]
Proceedings of the International Astronomical Union, 2011 AbstractThe techniques of disentangling were originally developed to separate spectra of individual components from time series of spectra of binaries and, simultaneously, to determine either the corresponding radial velocities or directly to solve for orbital parameters.Generalizations of the disentangling method enable us to include also intrinsic ...

FEBS Letters, EarlyView.Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

The Average Stellar Population Age and Metallicity of Intermediate-redshift Quiescent Galaxies
The Astrophysical JournalThe HectoMAP spectroscopic survey provides a unique mass-limited sample of more than 35,000 quiescent galaxies ( D _n 4000 > 1.5) covering the redshift range 0.2 10 ^11 M _⊙ ) assemble the bulk of their stars at earlier epochs.

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

Machine Learning for Stellar Magnetic Field Determination
International Journal of Computational Intelligence Systems, 2018 In this work we present the results for the automatic determination of the mean longitudinal magnetic field in polarized stellar spectra through the analysis of spectropolarimetric observations.
