DeepZoo: A cost‐effective and modular sampler for ecological studies in the deep ocean

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 10, Page 2895-2908, October 2026.
Abstract Understanding the structure and dynamics of deep‐ocean communities requires effective sampling of pelagic organisms in near‐bottom waters. These dispersive organisms contribute to biodiversity, connectivity and ecosystem recovery. Yet, current sampling methods remain constrained by size, cost, and depth, leaving key questions unanswered in ...

On 3‐MMC: A Cathinone I Have Come to Know and Love

open access: yesAnthropology of Consciousness, Volume 37, Issue 2, Fall 2026.
ABSTRACT This article attempts to complicate the mythology of a compound in a state of becoming. I will trace lightly its origins as a cultural disruptor and how I am implicated in this imperative. Introducing you to 3‐MMC will require multiple modes of storytelling and taking of liberties, drawing on literature reviews, practice‐based research, prose,
