The Scientist spoke with Jonathan Kagan about his idea that immune cells respond to “errors” made by unsuccessful pathogens, not the pathogens themselves.
Mixtures of viruses that attack inflammatory bowel disease–causing bacteria in mice also survive the digestive tract and are well-tolerated in humans, a study finds.
When soil heats up, microbes scale back protein synthesis machinery by making use of higher reaction rates that occur at higher temperatures, a study finds.
In work that has not yet been peer-reviewed, researchers present evidence that microbes can and do live inside the venom glands of several dangerous species. It remains unclear whether they’re to blame for infections linked to bites.
A massive screen of bacterial and archaeal genomes revealed five previously unknown instances where an organism uses an alternate code to translate genetic blueprints into proteins.
Researchers propose that some of the planet’s earliest photosynthesizers benefited from a slowing of the Earth’s rotation that allowed them to produce a surplus of oxygen and paved the way for more complex life.
The finding that a bacterium within a bacterium within an animal cell cooperates with the host on a biosynthetic pathway suggests the endosymbiont is, practically speaking, an organelle.
From fish harvests to cottonwood forests, organisms display evidence that species change can occur on timescales that can influence ecological processes.
A bacterium’s ability to distinguish self from non-self can arise spontaneously, a study shows, reigniting questions of whether the trait can be considered an adaptation.
