Post‐flight assessment of the OSIRIS‐REx Sample Return Capsule (SRC) for organic and other potential contaminants

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Regolith samples from the carbonaceous asteroid Bennu were stowed and delivered to Earth in the OSIRIS‐REx spacecraft's Sample Return Capsule (SRC). We applied multiple analytical techniques to study the components of the post‐flight SRC, with a focus on assessing the conditions and any contaminants to which the Bennu samples were exposed ...

Humidity‐driven shape morphing enhances fog harvesting in porous cactus spines

open access: yesNew Phytologist, EarlyView.
Spine straightening and water collection during fog exposure in Turbinicarpus alonsoi. Summary Cacti develop spines instead of conventional leaves, which often serve as mechanical defence against herbivores. However, some cactus species grow porous and flexible spines, suggesting fundamentally different functions.

Half a Century of Per‐ and Polyfluoroalkyl Substances in Northern Gannet Eggs: Impact of Regulations

open access: yesJournal of Applied Toxicology, Volume 46, Issue 11, Page 4085-4098, November 2026.
ABSTRACT Per‐ and polyfluoroalkyl substances (PFAS), known as “forever chemicals”, are persistent organic pollutants that have been widely used in the industry across the globe for many decades. Their chemical stability, bioaccumulation, and toxicity pose major environmental and health risks. This study examines temporal trends in the concentrations of

At‐nest drone monitoring causes minimal behavioural disturbance in breeding Eurasian Curlew

open access: yesEcological Solutions and Evidence, Volume 7, Issue 4, October–December 2026.
Incubating Eurasian Curlew taken with DJI Mavic 3T optical camera at a height of 25 m. Drone‐based monitoring of breeding Curlew in lowland England caused minimal behavioural disturbance. Although incubating birds frequently looked up at the drone, displacement from the nest was rare, suggesting that drones can provide an effective low‐impact ...

Biodiversity isn't measured in tons: Making sense of nature in the context of sustainable agriculture

open access: yesEcological Applications, Volume 36, Issue 7, October 2026.
Abstract In this review, we articulate several important but often overlooked concepts, trends, and perspectives in the biodiversity monitoring space, specifically in the context of transforming agriculture and the wider food system. We describe the common approaches to biodiversity monitoring—those focused on species, communities, functions, habitats,

Can Competition‐Based Programs Promote Conservation in Agriculture? Evidence From the “Most Crop per Drop” Contest

open access: yesWater Resources Research, Volume 62, Issue 10, October 2026.
Abstract This paper evaluates the Arkansas “Most Crop per Drop” Irrigation Yield Contest, a novel competition‐based Extension program designed to increase the adoption of Irrigation Water Management (IWM) practices among farmers. We use survey data to classify producers into three categories: contestants, informed non‐participants with some connection ...
