"Heat is a silent and invisible killer. It usually fails to generate the kind of spectacular imagery that lands weather on prime-time television or a newspaperโ€™s front page."

Trump Has Cut Science Funding to Its Lowest Level in Decades (Gift Article) The lag in funding extends far beyond D.E.I. initiatives, affecting almost every area of science: chemistry, computing, engineering, materials and more.

NSF Physics was cut by 85%, basically wiping out most of its capacity for supporting research.

NSF Astronomy was cut by 53%

Undergrad education was cut by 71% and research on learning by 79%

Graduate education was cut by 100% to ZERO.

Towards a โ€˜theory of changeโ€™ for ocean plastics: a socio-oceanography approach to the global challenge of plastic pollution - Microplastics and Nanoplastics Socio-oceanography is an emerging field which mobilises insights from natural and social sciences to explore the inter-connectedness of societal relationships with the ocean and to adopt a holistic approach to solving key oceanographic and societal challenges. It is within this specific context that we explore and reflect upon diverse communities in relation to engaging with plastic pollution in the ocean, one of the foremost socio-environmental challenges of our time. We establish definitions of โ€˜communityโ€™, arguing that communities are not โ€˜out thereโ€™ waiting to be engaged with but are dynamic and (re)constituted in four key contexts - geographical, practical, virtual, and circumstantial. We outline some โ€˜rules of engagementโ€™ and draw upon several international case studies in the context of plastic pollution to evidence and emphasise the value of working with members of diverse communities to better address socio-oceanographic challenges. In the context of plastic pollution, communities have a vital role to play in terms of co-creating knowledge, lived experience, diverse expertise, and agency to bring about social change. Given the ubiquity of plastics in our day-to-day lives, and subsequently as an environmental pollutant, no community is unaffected by this issue. Relating to socio-oceanography, we argue that structural power imbalances in terms of how diverse communities and natural scientists are traditionally positioned within academic research mean that โ€˜formalโ€™ scientific knowledge is frequently privileged, and members of communities risk being positioned as โ€™empty vesselsโ€™. Moving away from this โ€˜deficitโ€™ model where knowledge is simply transferred or alternatively extracted from communities allows us to progress towards an inclusive โ€˜socio-oceanography in societyโ€™ approach, where members of communities are valued as vital in prioritising and addressing socio-oceanography issues which affect everyday life. Accessibility, openness, ethics and fairness in data are also essential in ensuring that research outcomes can be applied widely outside the academic community. Graphical Abstract

Photoaging of Terrestrial Plastic Pollution: A Process Affected by Precipitation Rainwater is the primary water source with which terrestrial plastic pollutants interact. Not only could active substances in rainwater generate additional reactive oxygen species but water could also react with the photoaging intermediates of plastic. Precipitation and evaporation lead to repeated shifts between the solidโ€“liquid and solidโ€“gas interfaces during photoaging. To investigate the impact of these interfaces on photoaging, polyvinyl chloride, polypropylene, polystyrene, and polyethylene microplastics were exposed to UVA, UVB, or UVC radiation in common rainwater (CR), rainwater residue (RR), or rainwater-free (RF) treatments. Seasonal field exposure to the corresponding commercial plastics was also conducted. FT-IR spectroscopy was utilized to analyze the chemical changes in both microplastics and commercial plastics. Compared with RF and RR, CR exposure advanced the relative time of carbonyl production in the photoaging process. A model based on local precipitation and radiation data successfully predicted the carbonyl index of field-exposed commercial plastics and highlighted the importance of alternating interface transitions. The increase in the carbonyl index due to each wetโ€“dry cycle was 1.013โ€“5.460 times greater than that of plastics not exposed to rainwater. These findings indicate that plastics undergo different photochemical reactions on different interfaces, and alternating interface transitions can accelerate the photoaging of plastic.
