Rendezvous in Space: Tech Diplomacy and the Commercial Space Era—A Study of Rendezvous and Docking Technologies and Space Exploration Co‐Operation Since the Cold War

open access: yesGlobal Policy, EarlyView.
ABSTRACT On‐orbit rendezvous and docking constitute one of the most technically challenging activities in the history of space activities. As space endeavours mature to crewed missions, space rendezous and docking technologies (RDT) emerge as an area of technological innovation critical to advances in future crewed space exploration.

Field‐level crop choice responses to weather‐induced yield shocks in the US Corn Belt

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract As climate change increases the frequency and severity of extreme heat events, farmers are expected to face greater variability in crop yields. Using 10 million field‐level observations, this study examines how farmers in the US Corn Belt adjust corn–soybean rotation decisions in response to yield shocks largely driven by weather fluctuations.

Assessing Cognitive Workload and Performance in the Operating Room: Challenges in Applying NASA‐TLX Among Experienced Surgeons

open access: yesANZ Journal of Surgery, EarlyView.
ABSTRACT Background Surgical performance and cognitive workload (CWL) are central determinants of operative outcomes. Most prior studies have relied on simulated environments, limiting their clinical relevance. This pilot study aimed to evaluate the feasibility of using the National Aeronautics and Space Administration Task Load Index (NASA‐TLX) to ...

Occupational exposure to metal welding and cataract: A systematic review and meta‐analysis

open access: yesActa Ophthalmologica, EarlyView.
Abstract Background Metal welding generates ultraviolet radiation (UVR) of cataractogenic wavelengths, and UVR emitted during welding has been associated with cataract formation, but results from prior studies are conflicting. Methods We conducted a systematic review and meta‐analysis of epidemiological studies addressing associations between ...

Out There No One Has a Right to Die

open access: yesBioethics, EarlyView.
ABSTRACT The eventual goal of space exploration is to colonize exoplanets and their moons outside our solar system. This is a dangerous and immoral endeavour. The extraterrestrial life forms encountered would be hostile, vulnerable or both, and the descendants of the original pioneers would be involuntarily exposed to hazardous conditions and ...
