Injuries in deep time: interpreting competitive behaviours in extinct reptiles via palaeopathology

open access: yesBiological Reviews, EarlyView.
ABSTRACT For over a century, palaeopathology has been used as a tool for understanding evolution, disease in past communities and populations, and to interpret behaviour of extinct taxa. Physical traumas in particular have frequently been the justification for interpretations about aggressive and even competitive behaviours in extinct taxa.

Book Review: "Experiments Past" Edited by Jodi Reeves Flores and Roeland P. Paardekooper

open access: yesEXARC Journal, 2014
The publication in 1979 of the John Coles’ book Experimental Archaeology can be called the vademecum of the experimental archaeology. Many particular experiments have been published since then, such as A Bibliography of Replicative Experiments in ...

Quality Assessment of Box Materials for Long‐Term Archival Storage: VOC Emissions Are Not a Significant Concern

open access: yesChemPlusChem, EarlyView.
The image summarizes the main finding of our assessment of VOC emissions from archival box materials. VOCs from archive boxes were analyzed using GC–MS, IC, and Oddy tests. While some storage materials showed hazards at elevated temperatures, acetic and formic acid emissions at room temperature were very low.

Rapid Identification of New Psychoactive Substances in Letters by LA‐APCI‐MS

open access: yesDrug Testing and Analysis, EarlyView.
Laser ablation coupled to molecular mass spectrometry utilizing a modified atmospheric pressure chemical ionization source was used for the detection of synthetic cannabinoid receptor agonists in infused prison mail samples. ABSTRACT New psychoactive substances (NPS), especially synthetic cannabinoid receptor agonists (SCRA), are increasingly smuggled ...

The world's oldest man‐made biological experiment

open access: yesEcography, EarlyView.
Biological experiments are often short‐lived due to logistical or resource‐related challenges, and short‐term observations are extrapolated to make long‐term predictions. However, the effects of experimental treatments on biological communities and processes take time to develop.

Aqueous grinding synthesis of high‐performance alkali/alkaline earth metal‐tuned copper(I) iodide cluster scintillators for underwater x‐ray imaging

open access: yesInfoMat, EarlyView.
Highly efficient Cu(I)‐iodine cluster halides were synthesized via an aqueous grinding method, which is characterized by simplicity and environmental friendliness. One of the prepared NaCuI scintillator screens was integrated with a thin‐film transistor backplane array. The developed x‐ray flat‐panel detector exhibited outstanding operational stability
