This episode: Fruit fly gut microbes can mediate non-genetic traits passed from parents to offspring!
This episode: Bacteria rid themselves of burdensome waste by ejecting it inside little pieces of their own cell, called minicells!
This episode: Engineering other organisms to fix nitrogen by combining the required enzyme components into giant proteins that then get cut into the regular-sized subunit components!
This episode: Combining all 16 of yeast’s chromosomes into one or two only impairs their growth slightly in the lab, but it prevents them from successful mating with wild yeasts!
This episode: Some bacteria produce DNA-targeting toxins, which provokes a similar retaliation from other strains. Sometimes this hurts the provoker, but sometimes it is very helpful to them!
This episode: A new giant virus infecting marine algae brings its own genes related to fermentation, generating energy in the absence of oxygen!
This episode: Engineering yeast to control their metabolism using light and dark for the production of advanced biofuels and chemicals!
This episode: The bacterial immune system, CRISPR-Cas, can enhance gene transfer via transduction (phages carrying bacteria DNA) despite preventing it via conjugation!
This episode: A new giant virus has genes for a surprisingly complete system of protein synthesis!
This episode: A version of the microbial enzyme that fixes nitrogen can also convert carbon dioxide to methane!
