    Abstract

    With an alarming frequency, the United States is experiencing mass shooting events, which often result in heated public debates on firearm control. Whether such events play any role in recent dramatic increases in firearm prevalence remains an open question. This study adopts an information-theoretic framework to analyse the complex interplay between the occurrence of a mass shooting, media coverage on firearm control policies and firearm acquisition at both national and state levels. Through the analysis of time series from 1999 to 2017, we identify a correlation between the occurrence of a mass shooting and the rate of growth in firearm acquisition. More importantly, a transfer entropy analysis pinpoints media coverage on firearm control policies as a potential causal link in a Wiener–Granger sense that establishes this correlation. Our results demonstrate that media coverage may increase public worry about more stringent firearm control and partially drive increases in firearm prevalence.

    [–] A new study has shown that microplastics in soil can be harmful to worms, causing them to lose weight. Earthworms are an important part of farming as they help boost the nutrients found in the soil - so this latest form of plastic pollution is particularly bad news for farmers. mvea 118 points ago * (lasted edited 21 hours ago) in science

    The post title is a copy and paste from the subtitle and first three paragraphs of the linked popular press article here:

    A new scientific study has shown that microplastics in soil can be harmful to worms.

    The study by Anglia Ruskin University showed that tiny pieces of plastic cause the worms to lose weight.

    Scientists believe that the microplastics mainly affect a type of worm called the rosy-tipped earthworm.

    Earthworms are an important part of farming as they help boost the nutrients found in the soil - so this is latest form of plastic pollution particularly bad news for farmers.

    Effects of Microplastics in Soil Ecosystems: Above and Below Ground

    Abstract

    Environmental contamination by microplastics is now considered an emerging threat to biodiversity and ecosystem functioning. Soil ecosystems, particularly agricultural land, have been recognized as a major sink of microplastics, but the impacts of microplastics on soil ecosystems (e.g., above and below ground) remain largely unknown. In this study, different types of microplastics [biodegradable polylactic acid (PLA)], conventional high-density polyethylene (HDPE), and microplastic clothing fibers were added to soil containing the endogeic Aporrectodea rosea (rosy-tipped earthworm) and planted with Lolium perenne (perennial ryegrass) to assess the biophysical soil response in a mesocosm experiment. When exposed to fibers or PLA microplastics, fewer seeds germinated. There was also a reduction in shoot height with PLA. The biomass of A. rosea exposed to HDPE was significantly reduced compared to control samples. Furthermore, with HDPE present there was a decrease in soil pH. The size distribution of water-stable soil aggregates was altered when microplastics were present, suggesting potential alterations of soil stability. This study provides evidence that microplastics manufactured of HDPE and PLA, and synthetic fibers can affect the development of L. perenne, health of A. rosea and basic, but crucial soil properties, with potential further impacts on soil ecosystem functioning.
