The Lrs14‐Like AbfR1 Homolog From Metallosphaera sedula Is a Nucleoid‐Organizing Protein
MicrobiologyOpen, Volume 14, Issue 5, October 2025.Nucleoid organization in Crenarchaeota involves diverse small DNA‐binding proteins. The Lrs14‐type protein AbfR1 from Metallosphaera sedula binds nonsequence specifically across the genome and induces DNA condensation. These findings suggest a structural role for AbfR1Ms in chromatin architecture, functionally resembling bacterial nucleoid‐associated ...

Functional Ecology, Volume 39, Issue 10, Page 2588-2600, October 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Animal coloration serves a variety of visually related functions in nature (e.g. mate choice, aposematism and camouflage) but the pigments in integumentary tissues such as skin, scales and feathers may also serve functions unrelated to the visual environment (e.g ...

Occurrence of Pterin Pigments in Hymenoptera [PDF]
Nature, 1950 IT has been found that pterins exist in tissues of animals belonging to nearly all groups; their occurrence as pigments, however, is restricted to insects and cold-blooded vertebrates1,2. Among Lepidoptera, they are always present in the wing-scales of the Pieridae and appear to be a biochemical characteristic of that natural family3,4.

Metabolic Processes Preserved as Biosignatures in Iron-Oxidizing Microorganisms: Implications for Biosignature Detection on Mars [PDF]
Iron-oxidizing bacteria occupy a distinct environmental niche. These chemolithoautotrophic organisms require very little oxygen (when neutrophilic) or outcompete oxygen for access to Fe(II) (when acidophilic).

Diagnosis of tetrahydrobiopterin deficiency using filter paper blood spots: further development of the method and 5 years experience [PDF]
, 2018 In every newborn with even mild hyperphenylalaninemia (HPA) tetrahydrobiopterin (BH4) deficiencies need to be excluded as soon as possible. Differential diagnosis is most commonly performed by analysis of urinary neopterin and biopterin.

Fundamental Molecules of Life are Pigments which Arose and Evolved to Dissipate the Solar Spectrum
, 2014 The driving force behind the origin and evolution of life has been the thermodynamic imperative of increasing the entropy production of the biosphere through increasing the global solar photon dissipation rate.

Nitrogen Substrate Impacts Microcystis aeruginosa Exometabolome Composition
Environmental Microbiology Reports, Volume 17, Issue 5, October 2025.We used untargeted metabolomics to identify differences in the compounds exuded into culture media by three strains of M. aeruginosa grown on three N substrate treatments (NO3−, NH4+, and urea). Results showed that the usage of different N substrates changes the exometabolome of toxic and non‐toxic strains of M. aeruginosa.
