The slides: An evaluation of planetary health lecture slides for medical education.

Educational Challenge: There is an urgent need for innovations in planetary health medical education. Physicians must be prepared to provide high-value, low-carbon healthcare for patients increasingly impacted by the health consequences of climate change.

Proposed Solution: The slides, an evidence-based, open-access pedagogical tool that provides didactic planetary health medical education organized by medical subspecialty, was developed and evaluated by a virtual lecture session that presented a subset of the slides to  = 75 Canadian medical students.

Plasma cell-free DNA concentration increases during luteolysis in beef cows.

During cell death, DNA is fragmented and reaches the bloodstream in the form of cell-free DNA (cfDNA). Luteal cells must undergo an apoptotic process during structural luteolysis to begin a new oestrous cycle. We hypothesized that cfDNA concentrations would increase when inducing luteolysis by applying prostaglandin F (PGF2α) analog to the cycling cow.

Outdoor and synthetic performance data for PV devices concerning the weather conditions and capacitor values of I-V tracer.

This article presents the outdoor and synthetic performance data concerning the main electrical parameters estimated from the I-V curve for three photovoltaic technologies (HIT, m-Si and CIGS) and the weather conditions (irradiance, ambient and panel temperature). Synthetic data were generated by simulating in OpenModelica software the impact of weather conditions on device performance, considering an irradiance range between 50 and 1300 W/m. The outdoor data corresponds to the performance of the evaluated PV modules in outdoor tests in Medellin-Colombia for ten months using capacitive I-V tracers.

An extreme toughening mechanism for soft materials.

Soft yet tough materials are ubiquitous in nature and everyday life. The ratio between fracture toughness and intrinsic fracture energy of a soft material defines its toughness enhancement. Soft materials' toughness enhancement has been long attributed to their bulk stress-stretch hysteresis induced by dissipation mechanisms such as Mullins effect and viscoelasticity.
