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

Arabian 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.

Navigating the Flames: Comparative Analysis of Cremation Practices in the Roman and Early Medieval Periods at Gbely‐Kojatín (SK) and Přítluky (CZ)

Archaeometry, EarlyView.
ABSTRACT Cremation became the dominant funerary practice in the Middle Danube Region during the Roman Period (RP) (1st–4th century) and reappeared in the Early Medieval Ages (EMA) (6th/7th–8th century). This study aims to reconstruct differences in cremation conditions from the Gbely‐Kojatín site (Slovakia, RP and EMA) and the Přítluky site (Czech ...

Droughts and human impact in the ancient Uaymil region of the Maya lowlands inferred from a 2800‐year sedimentary archive at Lake Kaná, Mexico

Boreas, EarlyView.
The relationship between the climate and societal transformation in Maya lowlands has long been debated, particularly the role of drought in shaping the civilization trajectory during the Classic Period. A high‐resolution, multi‐proxy, geochemical record from Lake Kaná, located in the underexplored Uaymil region of the Yucatán Peninsula in Mexico ...

The Staircase Chart: Visualising Vertical and Cross‐Shelf Movements and Dispersal of Early‐Life Fish, Applied to Japanese Jack Mackerel

Fisheries Oceanography, EarlyView.
ABSTRACT Dispersal during early life stages is a critical process shaping marine fish connectivity and population dynamics, yet direct field observations at the individual level remain elusive. This has limited our understanding of the factors controlling dispersal, including the impact of active swimming by larvae and juveniles. Here, we present a new

Development of CCMb: A Low‐Mg Calcite Reference Material for In Situ Measurement of δ18O, δ13C and Selected Trace Elements

Geostandards and Geoanalytical Research, EarlyView.
Key Points Low‐Mg calcite RM developed for in situ microanalysis applications in palaeoclimatology (δ18O, δ13C; Mg, Sr m/m). New data for calcite CRM IAEA‐603 (δ18O, δ13C by SIMS and GS‐IRMS; Mg m/m). No detectable IMF effect of Mg on SIMS δ18O determinations for mass fractions < 3650 μg g‐1.

Klebsiella sp. strain B7 enhances alkaline tolerance by secreting pyruvic acid to accelerate L‐malic acid accumulation in soybean

Journal of Integrative Plant Biology, EarlyView.
Klebsiella sp. strain B7 acts as a positive regulator in alkaline stress responses in soybean. By activating pyruvic acid metabolism and L‐malic acid biosynthesis pathways, B7 significantly increases alkaline tolerance and yield in soybean. ABSTRACT Alkaline stress is a major constraint on crop growth and development and negatively impacts soybean ...

Anhydrous minerals in asteroid Bennu: Evidence for well‐preserved primordial components

Meteoritics &Planetary Science, EarlyView.
Abstract Aqueously altered carbonaceous astromaterials are dominated by secondary minerals, but a minor fraction of primary, anhydrous silicates and oxides escape alteration, offering insight into the original composition of asteroid parent bodies. We report the mineralogy, petrology, mineral chemistry, and oxygen isotopes of anhydrous minerals—50 ...
