Vincent, Elio and Michael discuss the stability of human coronaviruses on surfaces and in aerosols, and peptidoglycan production by a mosaic consisting of a bacterium within a bacterium within an insect.
The Fellowship of the TWiM reveal that colorectal cancer-associated microbiota are associated with higher numbers of methylated genes in colonic mucosa, and identification of metabolites needed by the fire blight disease bacterium for virulence in apples.
The Microbial Comrades present the oldest osteosynthesis in history, and how a small molecule produced by stressed bacteria is a warning signal that repels healthy populations to promote their survival.
The TWiM team reveals how ribosome modification resuscitates bacterial persister cells, and explain how a phage tail fiber protein exploits rotation of flagella to move towards the cell membrane.
At Georgia Tech, members and trainees of the Center for Microbial Dynamics and Infection discuss the identification of pathogen essential genes during coinfections, and how coral management can improve coral defenses against pathogens.
From ASM Microbe 2019 in San Francisco, Vincent speaks with Victoria McGovern, Carl Nathan, and Dan Portnoy about advancing human health through innovative collaborations.
The tetracoccal TWiM team visits Tardigrades on the Moon, and the twelve year quest to isolate an archaeon that provides insights into the emergence of the first eukaryotic cell.
Vincent meets up with Nick and Tal to explain how they engineered E. coli to lyse within tumors and deliver an antibody that causes tumor regression in mice.
The TWiM team reveals thousands of small novel genes in the human microbiome, and a mutualistic symbiosis between marine protists covered with magnetosome-containing bacteria.
Julie joins the TWiM team to reveal how microbiome and gut anatomy of a wood-feeding beetle promotes lignocellulose deconstruction, and bacteria that degrade PET plastic.
