Japanese collaborators detected all five nucleobases — building blocks of DNA and RNA — in samples returned from asteroid Bennu by NASA’s OSIRIS-REx mission.
29. January 2025/Kiel. Mangrove forests along the Amazon coast release significant amounts of trace elements such as neodymium and hafnium. These elements and their isotopic compositions can serve to understand the inputs of micronutrients which are vital for marine life. Researchers at the GEOMAR Helmholtz Centre for Ocean Research Kiel have investigated the processes behind these releases and their significance for the ocean. Their findings were recently published in the journal Nature Communications Earth & Environment.
In a paper just published in Nature Communications, researchers at the Industrial Sustainable Chemistry group of the University of Amsterdam (UvA) present a solution to the challenging problem of recycling polycotton textile waste. The process, developed in cooperation with the company Avantium, starts with fully removing all cotton from the fabric using superconcentrated hydrochloric acid at room temperature. The cotton is converted into glucose, which can be used as a feedstock for biobased products such as renewable plastics. The remaining polyester fibres can be reprocessed using available polyester recycling methods.
