NewsNo more copy-pasting: DNA base editing for better Lactobacillus strains
Scientists were able to edit the DNA of Lactobacillus strains directly without a template from other organisms. This technique is indistinguishable from natural variation and enabled them to create a strain that doesn’t produce diabetes-aggravating chemicals.

NewsSugar-mimicking molecule central to virulence of a common crop disease, study finds
A strain of Pseudomonas syringae manipulates plants by producing a substance called glycosyrin to suppress the immune response. New research shows that glycosyrin does this by mimicking galactose, acting like a wolf in sheep’s clothing.
