Scientists invent a way to create and dye rainbow-colored fabric in the lab using E. coli

Scientists used genetically modified bacteria to simultaneously create and color fabric in a one-pot method. Compared to current methods that rely on fossil fuels, this new technology provides a simpler and more sustainable way to produce colored fabrics. In a new study published Nov. 12 in the journal Trends in Biotechnology, researchers created cellulose-based fabrics […]

Mammoth RNA sequenced for the first time, a major leap towards understanding prehistoric life

Scientists have successfully sequenced the RNA of a woolly mammoth for the first time, dispelling the assumption that this fragile genetic molecule cannot survive from time immemorial. RNA, or ribonucleic acid, acts as a messenger that carries instructions between DNA and an organism’s protein-building machinery, converting genetic information into proteins. RNA can reveal which genes […]
