Iowa Population Exposures to Metals and Metalloids in Well Water

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Previous Iowa studies suggest low levels and chronic arsenic exposures are associated with prostate cancer. The rural Iowa population heavily relies on private wells for drinking water resources and thus is vulnerable to contaminants such as heavy metals found in well water.

The Earliest Feathers from the Lower Cretaceous Dabeigou Formation of North Hebei: Implications for the Early Evolution of the Jehol Biota

open access: yesIntegrative Zoology, EarlyView.
This study reports two isolated feather fossils from the Lower Cretaceous Dabeigou Formation in northeastern China. Morphological analyses identified them as the earliest known feathered theropods (potentially including avian) in the Jehol Biota. This finding reveals a complex ecosystem at the dawn of the Jehol Biota, bridging the temporal and faunal ...

A Bayesian classification model to reconstruct lifetime movement patterns of riverine fish using environmental tracers

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Environmental tracers, including both elemental concentrations and isotope ratios, are widely used to reconstruct the movement patterns of animals throughout landscapes. The methodology involves creating a map that describes the distribution of the environmental tracer across the landscape, an isoscape and then matching the values of the same ...

Bridging the Late Antique Gap in Northwest Arabia: New Archaeological Evidence on the Occupation of Wādī al‐Qurā (al‐ʿUlā [AlUla], Saudi Arabia) Between the Third and Seventh Centuries CE

open access: yesArabian Archaeology and Epigraphy, EarlyView.
ABSTRACT In 2019, the Dadan Archaeological Project (CNRS/RCU/AFALULA) identified a Late Antique village 1 km south of ancient Dadan in the al‐ʿUlā valley (northwest Saudi Arabia). Three excavation seasons at this site (2021–2023) have uncovered a massive building constructed in the late third or early fourth cent.

Greek ΜΝΗΣΘΗ and Aramaic DKYR in the Near East: A Comparative Epigraphic Study

open access: yesArabian Archaeology and Epigraphy, EarlyView.
ABSTRACT Past studies of graffiti containing the word ΜΝΗΣΘΗ have never fully established its intrinsic meaning. However, due to the existence of the Aramaic term DKYR, which carries a seemingly identical meaning to ΜΝΗΣΘΗ, in similar contexts in the Roman Near East, a comparison between both words is possible. Four distinct sites where the coexistence
