(created with BioRender.com) ABSTRACT Silky fowl, a unique chicken breed, exhibits black skin, meat, and bones due to the presence of natural melanin pigments. In our study, melanin from silky fowl (MSF) was isolated using an enzymatic extraction procedure and identified as a unique natural antioxidant.

Read the free Plain Language Summary for this article on the Journal blog. Abstract While fungal necromass is increasingly recognized as a major source of persistent carbon (C) in soils, the relative functional roles of bacteria and fungi in decomposing necromass are not fully resolved, and the processes that select for necromass decomposer communities

The Role of Pigments in Light Color Variation of the Firefly Photinus pyralis
We tested the novel hypothesis that genes encoding enzymes and transporters in pigment pathways (“pigment genes”) produce pigments in the firefly light organ that filter bioluminescent light, tuning the color of emitted light signals to match visual sensitivity. We detected the gene expression of 46 ommochrome and pterin pigment genes in P.

Update of the risk assessment of brominated phenols and their derivatives in food
Abstract The European Commission asked EFSA to update its 2012 risk assessment on brominated phenols and their derivatives in food, focusing on five bromophenols and one derivative: 2,4,6‐tribromophenol (2,4,6‐TBP), 2,4‐dibromophenol (2,4‐DBP), 4‐bromophenol (4‐BP), 2,6‐dibromophenol (2,6‐DBP), tetrabrominated bisphenol S (TBBPS), tetrabromobisphenol S

Purification, Characterization and Photodegradation\ud studies of modified sepia melanin (Sepia officinalis).\ud Determination of Eumelanin content in fibers from\ud Alpaca (Vicugna pacos). [PDF]
Currently melanins are still enigmatic bio-pigments bearing a structure as well as methods of determination not clearly fixed by the international scientific community. In many\ud respects melanins are unique among biopolymers.

Nanoparticle‐nanofiber hybrid systems comprised of melanin nanoparticles (MNPs) and polyvinyl alcohol (PVA), are fabricated through co‐electrospinning, and demonstrate potent antibacterial effects using photodynamic therapy. Upon exposure to UV‐A radiation, MNP‐PVA blend and core‐sheath nanofibers exhibits antibacterial activity against E. coli.

Single‐cell profiling of MC1R‐inhibited melanocytes
Research Highlights Single‐cell RNAseq of MC1R‐inhibited melanocytes elucidates a set of differentially expressed genes with no previous ties to pigmentation or melanocyte biology. This list includes Tbx3 which we show binds to T‐ and E‐boxes of candidate target genes, including those with known roles in pigmentation. Abstract The human red hair color (

Melanin Zinc Complex as a Biocompatible Agent for Clearing Bacteremia
Sepsis is whole‐body inflammation caused by the contamination of blood by bacteria and endotoxins. This study is to investigate the capability of eumelanin pigment to remove bacteria or endotoxins from the whole blood. The natural origin of melanin and its well‐documented biocompatibility makes it an ideal material to interface with human blood, which ...
