Artificial exposure to herbivore‐induced volatile organic compounds reduces herbivory and modulates gene expression in potato plants

Journal of Applied Ecology, Volume 63, Issue 8, August 2026.
These findings provide strong mechanistic evidence for VOCs mediating pest resistance and suggest that exposure to herbivore‐induced, plant‐derived VOCs can enhance pest resistance in potato crops. These results might offer novel information for developing ecologically sustainable plant volatile‐based strategies for boosting protection against pests in

Aedes albopictus and Dengue Transmission Risk in France Over the 21st Century

Global Change Biology, Volume 32, Issue 8, August 2026.
We assessed the impacts of climate change on the range expansion of Ae. albopictus and the risk of dengue transmission in France by 2085. Most of the French territory will be suitable to host this vector, while more than half of the territory will be suitable for dengue transmission.

How Different Patterns of Policy Attention Drive Policy Diffusion: Evidence From China's River Chief System

Policy Studies Journal, Volume 54, Issue 3, August 2026.
ABSTRACT Despite extensive research on policy diffusion, the ways in which policy attention influences this process remain underexplored. This study addressed this gap by distinguishing between three types of policy attention—political speeches, policy issuance and field visits—and investigating their differential impacts when delivered by central and ...

Prospective comparison of diagnostic accuracy of ultrasound, PET/CT and DW‐MRI for preoperative assessment of pelvic lymph nodes in cervical cancer patients: results of the CANNES trial

Ultrasound in Obstetrics &Gynecology, Volume 67, Issue 6, Page 836-851, June 2026.
ABSTRACT Objective To determine whether ultrasound is non‐inferior to positron‐emission tomography/computed tomography (PET/CT) and diffusion‐weighted magnetic resonance imaging (DW‐MRI) in terms of overall diagnostic accuracy for the preoperative assessment of pelvic lymph‐node status in cervical cancer.

Environmentally adjusted productivity growth and shadow prices for dairy farms

Canadian Journal of Agricultural Economics/Revue canadienne d'agroeconomie, Volume 74, Issue 2, Page 99-123, June 2026.
Abstract We estimate the environmentally adjusted productivity growth and shadow price for Ontario dairy farms. We use an input‐oriented directional distance function and farm‐level data from 2000 to 2020. First, we find that while GHG emissions per cow increase with higher milk yields, emission intensity decreases as milk yield per cow increases.
