Abstract Extension services are designed to facilitate the flow of information from researchers to farmers. However, information failures continue to impede the diffusion of soil‐improving and water conservation technologies in Sub‐Saharan African countries. We use a randomized controlled trial (RCT) to examine the impact of an extension‐based campaign

The limits of AI for authoritarian control
Abstract An emerging literature suggests that artificial intelligence (AI) can greatly enhance autocrats' repressive capabilities. This paper argues that while AI presents a powerful new tool for authoritarian control, its effectiveness is constrained by the very repressive institutions it is designed to serve.

Abstract The use of stone hammers to produce sharp stone flakes—knapping—is thought to represent a significant stage in hominin technological evolution because it facilitated the exploitation of novel resources, including meat obtained from medium‐to‐large‐sized vertebrates. The invention of knapping may have occurred via an additive (i.e., cumulative)

Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.

Trace Element Patterns in Juvenile Wild Chimpanzee Dentitions
ABSTRACT Trace elements are used to infer mammalian early‐life diets, environmental toxins, dispersal patterns, stress histories, and weaning ages. Here, we employ laser ablation‐inductively coupled plasma‐mass spectrometry (LA‐ICP‐MS) to reveal elemental patterns in our closest living relatives, chimpanzees.

What Do Lithics Tell Us About Cultural Evolution? Insights From the Central African Record
ABSTRACT While Western historical narratives often incorporate a biased vision of human evolution—driven by a progressive view tied to a progressively evolving state of culture—this paper proposes combining archaeological lithic data with epistemological reflections to critique the modern regime of historicity, where progress is assumed as rational ...

Abstract Scientific publications on AI education frequently express concerns that students at all educational levels, lacking sufficient AI literacy, may become passive learners due to the use of generative language models and blindly trust AI outputs.

The Australian Penile Cancer Clinical Registry: a comprehensive national approach to data collection
Background Penile cancer is a rare malignancy, with an Australian incidence of 0.6 in 100 000 men, with a wide range of clinical presentations, from localised, curable tumours to aggressive forms with high morbidity and mortality. Epidemiological data and management guidelines for penile cancer in Australia are limited.

Opioids in breast cancer: Between analgesia and modulation of tumour progression
Preclinical investigations consistently demonstrate that activation of μ‐opioid receptors and δ‐opioid receptors promote proliferation, migration, angiogenesis, epithelial‐mesenchymal transition, acquisition of cancer stem cell phenotypes, and chemoresistance.
