A coalition involving AIP, the European Science Federation, International Union of Pure and Applied Physics, and physical science organizations from 13 countries signed the global call to action regarding the role of physics to mitigate the climate crisis and embrace the idea of a green, environmentally sustainable economy. The organizations pledge to continue international collaboration in research, evolve physics education, focus engagement with governments to promote physics-based solutions, and welcome minoritized, excluded, and marginalized peoples to build careers in physics.
A research group at the University of Göttingen has long been researching manufacturing processes for products made of popcorn that are sustainable and efficient. The University has now agreed a licence agreement with the Bachl Group for the commercial use of the process and the products for building insulation.
Zinc deficiency is prevalent around the world, and among children, these mineral shortfalls can lead to stunting, embryonic malformations and neurobehavioral abnormalities. Over several decades, science has improved understanding of zinc metabolism, but an accurate, comprehensive assessment tool for its physiological status within a human body has remained elusive. Until now.
In a new study published in Nature on November 17, 2021, researchers from the University of Chicago used advanced electron microscopes to delve deeper into the process of protein degradation. They described the structure of a key enzyme that helps mediate ubiquitination in yeast, part of a cellular process called the N-degron pathway that may be responsible for determining the rate of degradation for up to 80% of equivalent proteins in humans.
The social cost of nitrous oxide, a greenhouse gas that is the largest remaining threat to the ozone layer, is understated, concludes an international team of researchers. In their assessment, the authors write that improving the accuracy of these calculations would not only give a more accurate picture of the impact of climate change, but also spur nations to more aggressively address it.
