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.

Timing the Sacred: A Multi‐Step Chronological Framework for the Llullaillaco Inca Burial

open access: yesArchaeometry, EarlyView.
ABSTRACT Absolute radiocarbon dating offers high precision, but its application to historical contexts, such as the Inca civilization, requires a rigorous methodological approach. This research examines methods to enhance chronological accuracy through a case study of artifacts from the Llullaillaco Capacocha sacrifice.

Dispersal, source and glass chemistry of a third tephra unit within Iceland's Settlement Layer

open access: yesBoreas, EarlyView.
Tephra layers may be studied to understand the dynamics and sequence of past explosive volcanism. In Iceland, the distinctive Settlement Layer (AD ~877) underlies almost all archaeological evidence for the Norse Settlement and is preserved in soils across Iceland and as cryptotephra overseas.

Depositional processes of varved sediments from proglacial Lago Frías since 1800 CE (North Patagonian Andes, Argentina)

open access: yesBoreas, EarlyView.
The glacierized Valle Frías in Northern Patagonia is one of the best‐studied valleys in South America and includes varved sediments from Lago Frías. We complement this lacustrine record with a high‐resolution documentation of varve counts and their composition.

Acute anaphylactic and multiorgan inflammatory effects of Comirnaty in pigs: evidence of spike protein mRNA transfection and paralleling inflammatory cytokine upregulation

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Rare but severe adverse events (AEs) associated with mRNA‐lipid nanoparticle (LNP) COVID‐19 vaccines, such as Comirnaty, include anaphylaxis and inflammatory organ disorders, but their underlying mechanisms are poorly understood. We aimed to develop an animal model to study these phenomena.

Feldspar Albitization With Implications for Reservoir Quality Evolution of Eocene Turbidite Sandstones in Offshore Espírito Santo Basin, Eastern Brazil

open access: yesJournal of Petroleum Geology, EarlyView.
ABSTRACT The diagenetic albitization of plagioclase and K‐feldspar grains is a transformative process that significantly alters sandstone's detrital composition and formation water chemistry, impacting reservoir quality. In this study, Eocene turbidite sandstones from the offshore Espírito Santo Basin, Brazil, were investigated to elucidate the role of

Agnosticism about artificial consciousness

open access: yesMind &Language, EarlyView.
Could an AI have conscious experiences? Answers to this question should be based not on intuition, dogma or speculation but on solid scientific evidence. However, I argue such evidence is hard to come by and that the only justifiable stance is agnosticism.

Epistocracy and the Commitment Problem

open access: yesPhilosophy &Public Affairs, EarlyView.
ABSTRACT The epistocracy debate has turned largely on the character of the electorate—what voters know, whether competence filters can be designed well, and what filtered selection produces. Another strand has focused on the legitimacy of epistocratic justifications. I ask instead about the equilibrium effects of the institution.
