Degradation of cell wall key in the spread of antibiotic resistance      (via sciencedaily.com)     Original source 

A study provides new clues in the understanding of how antibiotic resistance spreads. The study shows how an enzyme breaks down the bacteria's protective outer layer, the cell wall, and thus facilitates the transfer of genes for resistance to antibiotics.

Novel spectroscopy technique sheds light on NOx reduction      (via sciencedaily.com)     Original source 

The process that can convert pollution into benign by-products is called selective catalytic reduction, or SCR. Until now, it has been unclear how this reaction actually occurs, and contradictions have long existed between reaction models within the literature. Catalysis researchers used a technology called modulation excitation spectroscopy, or MES, to finally identify the correct pathway.

Melanin from cuttlefish ink as a sustainable biomass resource      (via sciencedaily.com)     Original source 

Melanin is a ubiquitous compound in nature, produced by many organisms. However, its potential as a biomass resource to produce value-added chemicals and materials remains relatively unexplored. In a recent study, researchers investigated the chemical decomposition of melanin derived from cuttlefish ink and showcased its application in the synthesis of biopolymer films and particles. Their efforts will hopefully pave the way to the adoption of melanin upcycling.
