Host Detection by Cuckoo Bumblebees: Choice Experiments Reveal Non‐Visual Cues Support Host Detection, but Accuracy Is Low

Entomologia Experimentalis et Applicata, EarlyView.
Female Bombus vestalis cuckoo bumblebees were introduced to a flight arena containing four identical opaque boxes, featuring slits to release volatiles from the bumblebees inside. When only one box contained a developing host colony, the cuckoos were able to locate their hosts among the four boxes with 66.2% accuracy.

Appraisal of Six Natural Mica Reference Materials for In Situ Rb‐Sr Geochronology

Geostandards and Geoanalytical Research, EarlyView.
Key Points Evaluated six natural mica reference materials for in situ LA‐ICP‐MS/MS Rb‐Sr geochronology using geochemical, microstructural and isotopic characterisation. Identified robust primary reference materials: Mount Dromedary biotite (99.37 Ma) and Mica‐Fe biotite (307.75 Ma). La Posta biotite and Högsbo muscovite are suitable secondary reference

Welfare Impacts of Agricultural Technology‐Utilization Regimes Among Rice Farmers in the Anchor Borrowers' Program in Southwest Nigeria

Review of Development Economics, EarlyView.
ABSTRACT Agricultural development interventions increasingly promote multiple technologies, yet farmers may utilize them differently, with uncertain implications for welfare. This study assesses whether alternative agricultural technology‐utilization regimes generate similar outcomes among rice farmers benefiting from the Anchor Borrowers' Program (ABP)

Safety in numbers: Tackling the deliberative, performative, and infrastructural roots of multi‐agent misalignment

AI Magazine, Volume 47, Issue 4, Winter 2026.
Abstract Multi‐agent systems (MAS)—a uniquely important subset of the wider field commonly called “Agentic AI”—enable complex work processes involving distributed networks of multiple AIs, people, and technology tools. However, they also carry big risks. Root causes of catastrophic safety failures in multi‐agent collaboration (as in human collaboration)

A simple empirical growing degree day model for predicting winter cover crop biomass in sandy soils

Agrosystems, Geosciences &Environment, Volume 9, Issue 4, December 2026.
Abstract The ecosystem services provided by cover crops (CCs) are related to their biomass production. The objective of this study was to develop a simple empirical model to enable farmers to predict CC biomass yields based on planting and termination timing, thereby improving the assessment of CC benefits. A field experiment was conducted over 3 years

Nonparametric Survival Estimation With Contaminated and Adjudicated Events

Scandinavian Journal of Statistics, Volume 53, Issue 4, Page 1520-1537, December 2026.
ABSTRACT We study the conditional expert Kaplan–Meier estimator, an extension of the classical Kaplan–Meier estimator designed for time‐to‐event data subject to both right‐censoring and contamination. Such contamination, where observed events may not reflect true outcomes, is common in applied settings, including insurance and credit risk, where expert

Canonical Antibodies Adopt Distinct Binding Modes to Recognize Viral Glycan Shields

Advanced Science, Volume 13, Issue 61, 3 November 2026.
Canonical Y‐shaped antibodies recognize viral glycan shields through adaptive Fab assembly states shaped by glycan organization and somatic hypermutation. Structural analyses ofbroadly neutralizing antibodies VRC35 and VRC36 across glycoproteins of HIV‐1, influenza, SARS‐CoV‐2, and Lassa viruses reveal distinct Fab assembly states, spanning monovalent,

Distance Sampling for Aerial Waterbird Surveys—Application to an Ephemeral Wetland of International Significance

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 11, November 2026.
ABSTRACT Ephemeral wetlands can radically change the ecology of arid landscapes but are difficult to robustly survey when flooded, challenging conservation management. The Fortescue Marsh (Martuyitha) is one of the largest water features of northwest Australia, with significant cultural and ecological value.
