One hypothesis about how life began on earth is that meteorites delivered amino acids—life’s building blocks—to our planet. Now, researchers reporting in ACS Central Science have experimentally shown that amino acids could have formed in these early meteorites from reactions driven by gamma rays.

The threat chemical pollution poses to biodiversity on a global scale has been acknowledged in the Post-2020 Global Biodiversity Framework. In its current form, Target 7 proposes to regulate the release of chemicals to the environment and names specific indicators focusing on pesticides, nutrients, and plastic waste. The Minamata Convention on Mercury reinforces that Target 7 of the Framework must include the following per new supporting publications: nonagricultural biocides, PFAS, toxic metalloids including mercury, and endocrine disrupting chemicals.
