Synchrotron X‐ray tomography and spectroscopy in numismatics: disclosing counterfeit practices in medieval silver coins

open access: yesJournal of Synchrotron Radiation, EarlyView.
Advanced synchrotron‐radiation‐based imaging and spectroscopic techniques were used to investigate the distribution and nature of mercury in numismatic artifacts, with a particular focus on its role in historical counterfeiting practices.This study explores the use of advanced synchrotron radiation (SR)‐based imaging and spectroscopic techniques to ...

AUGURAL TERRITORIES: On the Prophetic Organizing of the Mid‐range

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract In this article I introduce the concept of augural territories to theorize the urbanism that emerged during pandemic lockdowns. I draw on ethnographic research in Madrid to examine how community‐based responses—including mutual aid networks, food pantries and neighbourhood associations—disrupted the spatial and temporal logics of territorial ...

Evaluation of illicit drug contaminants in seized cannabis in Arizona and California, 2023–2024

open access: yesJournal of Forensic Sciences, EarlyView.
Abstract Despite public health concerns, fentanyl, cocaine, and other illicit drug contaminants remain largely understudied in unregulated cannabis. Here, we developed an analytical method to quantify a panel of common illicit drugs in cannabis and tested the law enforcement seizures in Arizona and California in evaluation of the illicit drug ...

Rapid hormonal rise in honey bees due to heat‐shock is mitigated by a primer pheromone

open access: yesInsect Science, EarlyView.
We show that honey bee foragers increased juvenile hormone (JH) titers significantly after heat‐shocked for 1 h at 40 °C, but this increase is dependent on social conditions. Increase of JH titers only happened when bees were isolated (one worker bee per vial) but not in groups.

Stable flies preferentially oviposit on sites offering conspecific eggs with egg‐derived bacterial semiochemicals

open access: yesInsect Science, EarlyView.
Stable flies preferentially oviposit on sites offering conspecific eggs with egg‐derived airborne semiochemicals. Egg‐borne bacterial symbionts, and Serratia marcescens in particular, produce odorants which attract gravid female flies and elicit oviposition.
