On the Raw Materials in the Ceramic Workshops of Jerusalem, Before and After 70 c.e.
Old City of Jerusalem and its Walls — 2020 — WHE4695DBAF28
A significant shift in ceramic production techniques and raw materials occurred in Jerusalem's pottery workshops following the city's destruction in 70 c.e. Petrographic analysis of 129 ceramics revealed that post-70 c.e., Jewish potters introduced new vessel types (e.g., dolia, mortaria) and building materials (roof tiles, bricks), using a distinct geological unit and intentionally adding quartz grains to enhance product toughness. This change likely reflects the workshops' transition under Roman military control, offering insights into their evolving production methods and potential links to other regional sites.
On the source “composition” of the bronze vessels in the burials of the Yinxu site
Yin Xu — 2020 — WHE062461BDA4
Bronze vessels from burials at the Yinxu site exhibit distinct 'source compositions,' revealing two primary types: single-sourced and multiple-sourced. This discovery challenges traditional analyses focused on 'assemblages' by emphasizing the origin, distribution, and social context of bronzes. The study analyzed key burials, including M303 at Dasikong, M1713 in the West Zone, Fu Hao's tomb, and M1046 at Liujiazhuang Locus North, demonstrating that multiple-sourced compositions vary based on social backgrounds and relationships among burial occupants. This approach offers new insights into the social dynamics and craftsmanship of Bronze Age societies.
Once Again: Who Captured Masada? On Doublets, Reading Against the Grain, and What Josephus Actually Wrote
Masada — 2020 — WHED49D13E709
A critical reassessment of Josephus' account reveals that Masada was captured by Jewish rebels, not Romans, during the First Jewish-Roman War (66 CE). The study challenges traditional interpretations by closely analyzing two conflicting passages in Josephus' 'War': one describing a Roman storming of Masada (2.408) and another attributing its capture to Eleazar ben Jair and the Sicarii (7.297). By avoiding overreliance on source-criticism or compositional analysis, the research demonstrates that Josephus' narrative is consistent when read contextually—both passages refer to Jewish rebels capturing Masada from Roman forces, with no actual doublet or intentional omission. This approach underscores the importance of contextual reading in historical texts.

Oral Processing Behavior of Diana Monkeys (Cercopithecus diana) in Taï National Park, Côte d’Ivoire
Taï National Park — 2020 — WHE715FB37B4A
Diana monkeys (Cercopithecus diana) in Taï National Park, Côte d’Ivoire, do not rely on difficult-to-process foods when preferred fruits are scarce. Instead, they maintain a diet of relatively easy-to-process items year-round, even as fruit availability fluctuates. The study analyzed 11,906 feeding events, revealing that invertebrates required the least oral processing, followed by fruits and leaves. Preferred fruits were processed with fewer mastications than nonpreferred ones, despite no direct link between fruit preference and availability. This behavior may stem from Taï Forest’s high tree diversity and productivity, offering a stable food source without clear fallback options. The research combined focal follows (2016–2017) with phenological surveys (2004–2009) to document dietary shifts and processing behaviors.
Organic Matter Clogging Results in Undeveloped Hardpan and Soil Mineral Leakage in the Rice Terraces in the Philippine Cordilleras
Rice Terraces of the Philippine Cordilleras — 2020 — WHEE1C70F077B
A critical threat to the UNESCO-listed Rice Terraces of the Philippine Cordilleras—flooded paddies at risk of collapse due to excessive water infiltration—has been linked to organic matter clogging rather than the intended hardpan formation. Research reveals that high organic matter content, which suppresses water drainage, leads to reductive soil conditions and mineral leaching (phosphorus, potassium, calcium, manganese). Field surveys and soil analysis demonstrated that undeveloped hardpans, combined with organic buildup, hinder terrace stability while depleting essential nutrients. Unlike hardpan formation, organic clogging is invisible from the surface, complicating management. The study advocates for pre-planting hard layer checks and post-crop drainage during the rainy season to mitigate risks while sustaining traditional farming practices.
Origins of the sarsen megaliths at Stonehenge
Stonehenge, Avebury and Associated Sites — 2020 — WHE79862C034E
New geochemical evidence reveals that the massive sarsen megaliths at Stonehenge likely originated from West Woods, Wiltshire. This discovery challenges previous assumptions about their source and sheds light on Neolithic transportation practices. Researchers analyzed trace elements in stone samples using advanced techniques, including laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). The findings suggest that the stones were quarried locally, transported over significant distances, and shaped with remarkable precision—implying sophisticated engineering capabilities during the late Neolithic period.
Ornithological discovery, exploration, and research on the Auckland Islands, New Zealand subantarctic
New Zealand Sub-Antarctic Islands — 2020 — WHE0C2DF27C45
Despite being the most researched and largest island group in New Zealand's subantarctic region, the Auckland Islands have lacked a comprehensive ornithological review. A database of 23,028 bird records from 1807 to 2019 reveals that over 76% of these observations remain unpublished, with significant contributions from historical expeditions like the Heritage Expedition and the Second World War Cape Expedition. The Auckland Islands host a high number of endemic bird taxa but have received limited research attention compared to other subantarctic islands, focusing primarily on large surface-nesting seabird species. Citizen science platforms, such as eBird, are emerging as valuable sources of data, with 1,597 unique records, and new vagrant species continue to be documented rapidly. This study highlights the gaps in ornithological research on the Auckland Islands while underscoring the potential of historical and citizen-science data to advance our understanding of its avifauna.

This discovery resolves long-standing confusion with its smaller relative, Othonna arbuscula, by highlighting distinct morphological features such as ascending rod-like stems, lateral spur-shoots, and sub-umbellate yellow flower heads that bloom leafless during autumn. The study, published in Bradleya, relied on field observations and taxonomic analysis to distinguish the new species within the Succulent Karoo Biome, contributing to the region's botanical diversity.
Out of India, thrice: diversification of Asian forest scorpions reveals three colonizations of Southeast Asia
Central Highlands of Sri Lanka — 2020 — WHE14AB761C4B
A groundbreaking study on Asian forest scorpions challenges the traditional 'Out of India' hypothesis, revealing three distinct colonization events into Southeast Asia during the Cenozoic era. By integrating divergence time estimation, ancestral range analysis, and diversification modeling, researchers traced the evolutionary journey of Heterometrinae scorpions from their African origins through the Cretaceous to their current distribution across South and Southeast Asia. The findings indicate that environmental stresses during the KT mass extinction led to range contractions in southern India and Sri Lanka's Central Highlands, followed by three dispersal events as the Indian subcontinent collided with Eurasia. This study not only refines our understanding of scorpion biogeography but also provides a framework for interpreting the complex dispersal patterns of other taxa in this biodiverse region.

Outsiders in the periphery: studies of the peripheralisation of low income housing in Ahmedabad and Chennai, India
Historic City of Ahmadabad — 2020 — WHE93B1CD988B
Residents of formal low-income housing on urban peripheries experience multifaceted disconnection, rendering them 'outsiders in the periphery.' This dynamic is driven by three key factors: the lack of resident involvement in housing production due to pre-built units, spatial isolation limiting mobility and socioeconomic opportunities, and substandard infrastructure that hinders place-making. The study, based on mixed-method fieldwork in Ahmedabad and Chennai, challenges conventional narratives around urban peripheralization, which typically focus on high-end or informal settlements. It reveals how formal low-income housing, increasingly constructed on isolated sites, fails to integrate residents socially or spatially, undermining the inclusive potential of affordable urban development.
