Skeletons of swiftly swimming sharks: Three‐dimensional analysis of lamniform vertebral morphology and mineral architecture

open access: yesJournal of Anatomy, EarlyView.
We examined morphology, 3D arrangement, and mineral amount in cartilaginous vertebrae from four lamniform shark families (Alopiidae, Carchariidae, Cetorhinidae, and Lamnidae). We identified family‐specific mineralization trends, and regional patterning of structures along the column.

Widespread complex enameloid microstructure in teeth and rostral denticles of Cretaceous sclerorhynchoid skates (Rajiformes: †Sclerorhynchoidei)

open access: yesJournal of Anatomy, EarlyView.
This article demonstrates that the teeth and rostral denticles of an extinct clade of sawfish‐like skates display an extremely derived enameloid microstructure, similar to what is known among sharks. The presence of tooth‐like enameloid microstructure in dermal denticles opens new perspectives about the origins and development of chondrichthyan ...

Driven by risk: Understanding reference‐dependent preferences using simulated auto racing

open access: yesJournal of Risk and Insurance, EarlyView.
Abstract Using data from over 56,000 simulated auto races worldwide, we analyze risk‐taking at the margins, consistent with reference‐dependent preferences. We show that participants' risk‐taking changes when a desired intermittent outcome is presented, sometimes at the expense of a more favorable expected end state.

Understanding marine biodiversity patterns and drivers: The fall of Icarus

open access: yesMarine Ecology, EarlyView.
Abstract Biodiversity patterns are fundamental in our understanding of the distribution of life, ecosystem function, and conservation. In this concept analysis, A survey of the existing knowledge on marine biodiversity patterns and drivers across latitudes, longitudes, and depths indicates that none of the postulated patterns represent a rule.

“Buprenorphine doesn't hold me”: Neurochemical afterlives of state violence and the struggle for meaning in addiction treatment

open access: yesMedical Anthropology Quarterly, EarlyView.
Abstract This paper analyzes two disparate experiences of buprenorphine, a medication for opioid addiction, in California. Within the context of the U.S. War on Drugs and after decades of criminalization, buprenorphine represents a shift toward outpatient medical treatment of opioid addiction, but it has been unequally distributed and experienced ...
