Planetary bodies like Mars, Europa, and Enceladus pose the question, "How to study them without contaminating them and destroying future prospects to detect life, if it is there?" The natural trade-off, of course, is that the cleaner your spacecraft, the more you can explore such a body without risk of contaminating it. As chartered by NASA Headquarters, the Planetary Protection Technology Definition Team (PPTDT) was asked to provide a report covering six different areas related to the engineering and technology challenges of implementing planetary protection requirements on solar system exploration missions.

State Key Laboratory of Urban and Regional Ecology, Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences, Beijing, China.
The Sustainable Development Goals (SDGs) provide a comprehensive framework for societal progress and planetary health. However, it remains unclear whether universal patterns exist in how nations pursue these goals and whether key development areas are being overlooked. Here, we apply the product space methodology, widely used in development economics, to construct an 'SDG space of nations'.

Background: Nature-based interventions (NBIs) benefit human well-being, but clinical trials comparing different NBIs in various natural environments are scarce.
Objective: To evaluate the efficacy of a multicomponent nature-based intervention (MNBI) in comparison to control group (classical forest bathing).
Primary Outcome: well-being; Secondary outcomes: vitality, happiness, connection, and engagement with nature across urban, peri-urban, and rural areas.
Human and Veterinary Medicine Collaboration: Synergistic Approach to Address Antimicrobial Resistance Through the Lens of Planetary Health.
Antibiotics (Basel)
January 2025
Department of Veterinary Medicine, Faculty of Agriculture, University of Novi Sad, Trg Dositeja Obradovica 8, 21000 Novi Sad, Serbia.
Antimicrobial resistance (AMR) represents a critical threat to human, animal, and environmental health, challenging global efforts to maintain sustainable ecosystems and public health systems. In this review, the complex, cross-disciplinary issues of AMR are explored within the framework of planetary health, emphasizing the interconnectedness of human and veterinary medicine with broader environmental and social systems. Specifically, it addresses the social, economic, environmental, and health dimensions of AMR under the planetary health framework.

Nitryl chloride (ClNO) is a key precursor of chlorine radicals, influencing atmospheric oxidation and secondary pollutants formation. Few studies have examined the ClNO chemistry from the perspective of the planetary boundary layer. Here, we conducted a vertically resolved investigation of ClNO at six heights (ranging from 5 to 335 m) on a 356 m tower in the Pearl River Delta, China, during winter 2021.
