“Flames Over Persepolis”: New Scientific Evidence Supporting Historical Perspectives

open access: yesArchaeometry, EarlyView.
ABSTRACT This study investigates the burning of Persepolis Terrace, historically attributed to Alexander III in 330 bce. A review of classical accounts and excavation reports, combined with diagnostic surveys, confirms the fire's historicity and provides novel insights.

Response of Remote Tropical West Pacific Islands to Climate Variability: A Multiproxy Record From T‐Lake, Palau, Spanning the Early Holocene to Present

open access: yesArchaeometry, EarlyView.
ABSTRACT Lake sediments are natural archives of past environmental dynamics and how these systems have responded to past climate variability. Sediment geochemistry, governed by local geology and climate processes, is unique to each lake‐catchment and geochemical proxies must be validated for each study site.

Red era: Dyeing yak hair fibres red with in situ generated silver nanoparticles using silver nitrate and a flavonoid‐containing plant extract

open access: yesColoration Technology, EarlyView.
Abstract Plants and their extracts have been used for dyeing fabrics, skin and hair for thousands of years and have been experiencing a revival in the last years due to increasing health risks arising from oxidative hair dye precursors. We developed a novel two‐step method to dye keratin fibres based on in situ formed silver nanoparticles including a ...

Phycocyanobilin biosynthesis in Galdieria sulphuraria requires isomerization of phycoerythrobilin synthesized by bilin reductases

open access: yesThe FEBS Journal, EarlyView.
The biosynthesis of bilins, tetrapyrroles essential for light harvesting and sensing, is performed by specific enzymes (FDBRs). In Galdieria sulphuraria, both phycobiliprotein types bind phycocyanobilin, despite lacking the canonical synthesizing gene PCYA. Instead, PEBA and PEBB are encoded, producing phycoerythrobilin, proposed to be later isomerized

Human IDO2 exhibits unique binding affinities distinct to those of human IDO1

open access: yesThe FEBS Journal, EarlyView.
Although indoleamine 2,3‐dioxygenase 2 (IDO2) is highly homologous to IDO1, it displays markedly lower catalytic activity. We found that IDO2 binds L‐tryptophan (L‐Trp) in a flipped orientation stabilized by the IDO2‐specific residue His143. Replacement of His143 with the IDO1‐equivalent tyrosine restored an IDO1‐like binding mode and increased ...

Compound‐Specific Stable Isotope Analysis Reveals Population‐Specific Differences in Chinook Salmon Trophic Level and Basal Resource Use in the Northeast Pacific

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT Chinook salmon exhibit far‐flung and disparate population‐specific marine migrations that have made it difficult to assess their trophic ecology. In this study, we collected returning and resident subadult Fraser River Chinook salmon in 2018 and 2019 from population groups with different known run‐timings (spring, summer, and fall) and marine ...
