The Alignment Risks of AI Overconfidence about Consciousness

open access: yesJournal of Applied Philosophy, EarlyView.
ABSTRACT Many contemporary AI systems (as of May 2025) have expressed extreme confidence in current and near‐future AI lacking consciousness and moral patiency. This article argues that artificially reinforcing such confidence, even if pragmatically useful, poses a novel alignment risk: as coherence‐seeking AIs become more epistemically principled ...

Farming in the shadows of Rome: A multi‐proxy palaeoenvironmental record from Loch Clunie—Perthshire

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Roman impacts on local society is a subject of international significance. Loch Clunie, Perthshire, lies only 5.4 km from Inchtuthil, the only Roman legionary fortress in Scotland, and contains two crannogs and a probable lakeside hillfort. Despite this proximity and the likelihood of local–Roman interaction, these sites remain unexcavated ...

Citrus depressa peel extract and its polymethoxyflavones mitigate acetaminophen‐induced chronic liver injury in mice through antioxidant activation, epigenetic regulation, and gut microbiota modulation

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Preventing chronic liver damage is essential for maintaining overall health and reducing the risk of serious liver diseases. Acetaminophen (APAP) overdose can lead to severe liver damage due to oxidative stress, and citrus fruits are rich in bioactive compounds that may have health benefits.
