The abundance of pollen coat small signaling proteins shows limited convergence between independent selfing transitions in Arabidopsis and Capsella

New Phytologist, EarlyView.
Summary In plants, a key example of convergence is the repeated evolution of floral traits associated with the transition from outcrossing to self‐fertilization, often resulting in the ‘selfing syndrome’ (e.g. reduced flower size and loss of scent). However, potentially overlooked changes concern the pollen coat, which plays a role in different aspects

C4 photosynthetic anatomy is associated with higher leaf hydraulic conductance and capacitance in Alloteropsis semialata

New Phytologist, EarlyView.
Bulk leaf capacitance (Cbulk) in relation to bundle sheath area (BSA) and leaf dimensions in Alloteropsis semialata plants differing in photosynthetic type (C3, C3–C4 or C4) and ploidy level (2x, 6x or 12x). Summary The evolution of C4 photosynthesis requires biochemical innovations to be coordinated with anatomical modifications.

From Everyman to Hamlet: A Distant Reading

Renaissance Studies, EarlyView.
Abstract The sixteenth century sees English drama move from Everyman to Hamlet: from religious to secular subject matter and from personified abstractions to characters bearing proper names. Most modern scholarship has explained this transformation in terms originating in the work of Jacob Burckhardt: concern with religion and a taste for ...

Measuring inequality in access to English across East Asia

World Englishes, EarlyView.
Abstract This study statistically examines disparities in access to acquiring English language proficiency (ELL‐access gaps) in China, Japan, South Korea and Taiwan, using nationally representative survey data and a model that assumes causal relationships of ‘social origins → English proficiency’.

Blood flow restriction: The acute effects of body tilting and reduced gravity analogues on limb occlusion pressure

Experimental Physiology, EarlyView.
Abstract Blood flow restriction (BFR) has been identified as a potential countermeasure to mitigate physiological deconditioning during spaceflight. Guidelines recommend that tourniquet pressure be prescribed relative to limb occlusion pressure (LOP); however, it is unclear whether body tilting or reduced gravity analogues influence LOP.

Uncovering the impact of the cardiovascular system on cerebrovascular health using MRI

Experimental Physiology, EarlyView.
Abstract Human cerebrovasculature is finely tuned to enable local changes in blood flow to meet the brain's demands, whilst protecting the brain from systemic changes in blood pressure, both acutely during a heartbeat and chronically over time. This review summarises cerebrovascular structure and function, their role in disease and neurodegeneration ...
