Scientists have designed a new material system to overcome one of the biggest challenges in recycling consumer products: mixed-plastic recycling. Their achievement will help enable a much broader range of fully recyclable plastic products and brings into reach an efficient circular economy for durable goods like automobiles. Read more »
Designer Materials to Keep Plastic Out of Landfills
Scientists have designed a new material system to overcome one of the biggest challenges in recycling consumer products: mixed-plastic recycling. Their achievement will help enable a much broader range of fully recyclable plastic products and brings into reach an efficient circular economy for durable goods like automobiles. Read more »
Missing Lysine Link Could Improve Plant-Based Nutrition
To engineer crops with higher levels of the important amino acid, lysine, researchers solved the structure of an enzyme that helps break down lysine in plants. A fuller understanding of the factors affecting lysine levels should aid in the successful development of stable high-lysine crops to combat malnutrition globally. Read more »
Study Leads to Firmer Grasp of Biochemical “Reactive Handle”
Protein crystallography provided new insight into a functional group of molecules that, if added to bacterial enzymes, could enable a variety of alterations to the bacteria’s polymer output. Tweaking enzymes to produce these “reactive handles” is a first step toward biosynthesizing diverse polymers with tailored properties. Read more »
How Light-Harvesting Bacteria Toggle Off and On
Researchers clarified the atomic-level mechanism that enables bacteria to switch light harvesting off and on in response to potentially damaging overexposure to light. The results could have long-range implications for artificial photosynthesis and optogenetics—the use of light to selectively activate biological processes. Read more »
