Two sides of the same coin: Weathering differences of plastic fragments in coastal environments around the globe.

Plastic debris in coastal environments usually undergoes weathering due to various environmental conditions. However, the weathering effects on exposed and shaded sides of the same plastics are underexplored. In this study, 1573 plastic fragments were collected from 15 coastal sites worldwide between December 2021 and December 2022, and weathering experiments were conducted outdoors.

A perspective on the methodological challenges in the emerging field of antifouling paint particles.

Antifouling paint particles are anthropogenic particles primarily originating from marine coatings. Recent investigations have shed light on their toxicity at concentrations found in the environment. However, several significant challenges still impede accurate antifouling paint particle quantification.

Space Analogs and Behavioral Health Performance Research review and recommendations checklist from ESA Topical Team.

Space analog research has increased over the last few years with new analogs appearing every year. Research in this field is very important for future real mission planning, selection and training of astronauts. Analog environments offer specific characteristics that resemble to some extent the environment of a real space mission.

Microplastics in marine sponges (Porifera) along a highly urbanized estuarine gradient in Santos, Brazil.

Microplastics (MPs) are ubiquitously found in environmental matrices, particularly affecting aquatic systems. While several marine species have been widely used to assess MP contamination, sponges (Porifera) are less used. The MPs contamination was assessed in the sun sponge (Hymeniacidon heliophila) along a gradient at the Santos Estuarine System (Brazil).
