Good Morning! Highlights of today’s digest include a revisited study that showed a significant alterations in the gut microbiome by the consumption of low/no-calorie sweeteners (LNCS), such as Splenda, and raising safety concerns, another work tells us development of Burkholderia-free host plant model to show how Burkholderia helps plant development, and finally a study finds a mechanistic link between the gut microbiome and early childhood asthma as shown with highthened expression of bacterial genes that make 12,13-diHOME which alters immune response.
