Drone-Assisted Organ Transport: A Scoping Review of Clinical, Regulatory, and System Readiness. [PDF]
Clin TransplantABSTRACT Organ transport remains a critical determinant of transplant success, with delays during transfer prolonging cold ischemia time (CIT) and increasing the risk of delayed graft function or organ discard. Uncrewed aerial vehicles (UAVs) have emerged as a potential means to enhance the speed, predictability, and resilience of transplant logistics.

Integrating livestock and cropping systems: Interseeding cereal rye into corn for grazing. [PDF]
J Environ QualAbstract Interseeding annual forages into growing corn may be an alternative for both cover and grazing in temperate regions of the United States. A 4‐year experiment evaluated the effect of interseeding cereal rye (Secale cereale) into corn for grazing after harvest on corn grain, forage biomass yield and quality, soil health, and estimated spatial ...
