DNA barcoding of more than one million insect specimens indicates that at least one third of California's insect biodiversity remains undiscovered

open access: yesEcography, EarlyView.
Insects are the most diverse terrestrial organisms, yet they are underrepresented in large‐scale conservation assessments. To address this gap, the California Insect Barcoding Initiative is developing a publicly accessible, statewide DNA‐barcode reference library for California insects to support scalable surveys, establish baseline biodiversity ...

Opium trade and use during the Late Bronze Age: Organic residue analysis of ceramic vessels from the burials of Tel Yehud, Israel

open access: yesArchaeometry, EarlyView., 2022
Abstract Organic residue analysis was conducted on various vessels from burials at Tel Yehud, Israel. The analyses led to new reliable evidence for the presence of opioid alkaloids and their decomposition products. This research revitalizes a decades‐old discussion on the presence and function of the opium trade across a cultural region of utmost ...
