Persistence

Abstract. While plastic pollution threatens ecosystems and human health, the use of plastic products continues to increase. Limiting its harm requires design strategies for plastic products informed by the threats that plastics pose to the environment. Thus, we developed a sustainability metric for the ecodesign of plastic products with low environmental persistence and uncompromised performance. To do this, we integrated the environmental degradation…

Recent research from the University of Otago indicates that the Antarctic ozone hole has been significantly larger and more persistent than commonly believed, not solely due to CFCs. The study links the hole to changes in the Southern Hemisphere’s climate and weather patterns, despite the Montreal Protocol’s efforts.A new study reveals the Antarctic ozone hole is larger and more enduring than thought, with complex factors beyond CFCs contributing to its persistence and impact on the Southern Hemisphere’s climate.Despite…

Sankey diagram of retrospectively constructed mobility between productivity classes in the three stages of an academic career. All STEMM disciplines (total) are combined, and only current full professors are shown. Top (upper 20%), middle (middle 60%), and bottom (lower 20%) productivity classes are shown in percentages of 100% (or rounded) in each of the three classes. The bottom class in the left column is larger than 20%, and the middle class is…

New research from Washington University in St. Louis finds individuals who live in areas that historically favored men over women display more pro-male bias today than those who live in places where gender relations were more egalitarian centuries ago. Credit: Monica Duwel/WUSTL New research from Washington University in St. Louis provides evidence that modern gender norms and biases in Europe have deep historical roots dating…

A screenshot of a Strava heatmap of Baltimore.Screenshot: Strava/Alison Mariella DésirIf you see a jogger, you’re probably in a white neighborhood. That’s according to Strava data from major cities like New York City and Baltimore, which show that running paths mirror American segregation. Running requires the perception of safety of multiple kinds, a necessity Black neighborhoods have long been denied. In February 2020, Ahmaud Arbery was murdered while jogging in Georgia, the victim of a racist hate crime. He had run…
