Evergreen idea turns biomass DNA into degradable materials

Scientists are turning DNA from organic matter - such as onions, fish and algae - into biodegradable gels and plastics. The resulting materials could be used to create everyday plastic objects, unusually strong adhesives, multifunctional composites and more effective methods for drug delivery, without harming the environment the way petrochemical-based materials do.

Better understanding of nature's nanomachines may help in design of future drugs

Many of the drugs and medicines that we rely on today are natural products taken from microbes like bacteria and fungi. Within these microbes, the drugs are made by tiny natural machines - mega-enzymes known as nonribosomal peptide synthetases (NRPSs). Researchers have gained a better understanding of the structures of NRPSs and the processes by which they work.
