Small Things Considered

Psittacofulvin: Polly's Peculiar Plumage Pigment

by Janie
In macro-fauna, eye-catching colors typically serve two purposes: to woo potential mates, or to signal that the creature is not a snack and will in fact poison you. This is where parrots diverge – and get embroiled in connections to microbiology... Read more →

Sulfur disproportionation is exergonic in the vicinity of marine hydrothermal vents

by Elio
Now that’s a title of a paper for you. I confess, it baffled me. At a minimum, I had to look up "disproportionation". What is it? Also known as "dismutation", this refers to a redox reaction in which a compound that is partly oxidized converts to two compounds... Read more →

Giant Soil Viruses

by Abigail Curtis
My first niche microbiological interest came freshman year of high school, when I discovered that viruses don't solely infect animals. Indeed, viruses are pervasive in every ecosystem, including the smallest ones in the ground. The aspect of viruses in microbial ecosystems... Read more →

Why aren’t any Archaea known to make spores? Read more →

"Off with Their (tRNA) Heads"

by Janie
Some bacterial molecules have the social graces of certain 1700s French revolutionaries, or Shakespeare's Richard III, or the Queen of Hearts from Alice’s Adventures in Wonderland – in that all share a penchant for beheading those they encounter! In the microbial case... Read more →

Heavy-duty Traffic, Microscale

by Christoph
Men­tion "fla­gel­la" and we mi­cro­bio­lo­gists in­stant­ly think of these in­gen­ious ap­pe­nda­ges that bac­te­ri­al cells use to pro­pel them­selves through fluids of va­ry­ing vis­co­si­ties (ar­chaea do this, too, with their ar­cha­el­la). We ra­re­ly think of them as an ac­ces­sory to trans­port car­go. Yes "car­go," you read cor­rect­ly, but may­be you re­mem­ber... Read more →

Consider Keeping Small Things in Perspective

by Roberto
Our previous post was a bit unusual for STC, the transcription of a talk I had given a few weeks earlier. First and foremost, I want to express my gratitude to Christoph who proposed the idea for that post. Let me also elaborate on the ending of that presentation... Read more →

Thinking outside the rod (or coccus)

A rose is rose is a rose is a... roseota?

by Roberto
Give me a chance to quote Gertrude Stein and I'll do so gladly. This time the opportunity was handed to me on a silver platter. On October 2021, almost out of the blue, the International Committee on Systematics of Prokaryotes (ICSP) published a paper with the "names and formal descriptions... Read more →
