In this episode we hear about echolocation, bacteriophages, babies and pain, a neural code for food abundance, and how zebrafish can make their own sunscreen.
Killing their neighbors allows bacteria to steal genes, including antibiotic resistance genes, which we observed under a microscope, quantified, modeled, and predicted potentially guiding strategies to combat it.
Co-evolving residue pairs in the different components of a protein complex almost always make contact across the protein–protein interface, thus providing powerful restraints for the modeling of protein complexes.
Functional definition of NrtR and the discovery of its acetylation represents a first paradigm for linking protein acetylation to bacterial central NAD+ metabolism.
Quantifiable bioenergetic parameters, determined from extracellular flux analyses, are distinct between macrophages infected with Mycobacteriumtuberculosis or vaccine strain M. bovis BCG, enabling assessment of future vaccine and drug efficacy.
Metabolomics and stable isotope labelling studies of virulent Mycobacterium tuberculosis reveal a de-centralised metabolic network able to utilise various amino acids as nitrogen sources to a better extent than ammonium.
Mutations in several components of a bacterial ribosome are shown to broadly decrease antibiotic and stress sensitivity, and readily accessible reversion mutations allow these ribosomal mutations to serve as stepping stones to high level antibiotic resistance.
A continuum of genome relationships is discovered through comparative genomics of 627 sequenced mycobacteriophages isolated and characterized in an integrated research/education initiative.
The structure of the endogenous ESX-3 secretion system reveals a highly coordinated inner membrane complex and suggests a mechanism for the regulated secretion of ESX substrates.
