So happy to see Mark recognised for his incredible work. Over a ~40 year career he and his group discovered ECF sigma factors, characterised many key developmental regulators of the Streptomyces lifecycle, and identified new mechanisms of bacterial gene regulation, antibiotic action and resistance.

Highlights from our recent participation!

Members of the Multi-Defence Consortium presented both talks and posters on phage defence systems β€” showcasing exciting progress across the field.

Great discussions, great science, and we’re excited to share more soon!

Exciting news! I have two positions open in my lab at the UoManchester: one PDRA and one Research Tech.
Join our team to study evolutionary mycology and help us understand antifungal resistance in fungal pathogens. A fantastic opportunity to join the brilliant Manchester Fungal Infection Group!

Thanks Emm! Very interesting read! And soooo much work! Good to see progress on efficiency and specificity of LSRs as genome integration tools.

Like antibiotics, we know antimicrobial peptides select for resistance in bacteria, but worse that peptide resistance can also cross-protect against host peptides, potentially undermining immunity. Caution required, not talk of β€œgoldmines” on R4 Today
