“Is This Edible Anyway?” The Impact of Culture on the Evolution (and Devolution) of Mushroom Knowledge

open access: yesTopics in Cognitive Science, EarlyView.
Abstract Mushrooms are a ubiquitous and essential component in our biological environment and have been of interest to humans around the globe for millennia. Knowledge about mushrooms represents a prime example of cumulative culture, one of the key processes in human evolution.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

open access: yesExperimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Measuring the Milky Way Vertical Potential with the Phase Snail in a Model-independent Way

open access: yesThe Astrophysical Journal
The vertical phase-space spiral (snail) is a direct sign of disequilibrium of the Milky Way’s disk. Nevertheless, the wrapping of the phase snail contains information on the vertical potential.

Placental mitochondrial metabolic adaptation maintains cellular energy balance in pregnancy complicated by gestational hypoxia

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Placental mitochondrial adaptation to gestational hypoxia. Hypoxic pregnancy in sheep increases placental insulin like growth factor 2 (IGF2) signalling (1), which is associated with a shift in capacity away from β‐oxidation (2) and complex I‐mediated respiration (3), while maintaining total oxidative phosphorylation capacity (4).
