I 100% concur with Barak about our great Microbiome Digest, and we invite YOU to join us to create useful content for our community. Today’s Digest hopefully brings you much food for thought. I would draw your attention towards two papers about insecticide and antibiotic resistance. The first is about the mechanism for malaria transmitting mosquitoes to tolerate the common pesticide, pyrethroid. The second is on a potential genetic engineering approach to replacing antibiotic resistant plasmids with artificial ones. Of course, there are many more articles and news pieces to read from. Enjoy!
