Small Things Considered

In the Company of Bacteria: Amoebae

by Christoph
In times long past, highly evolved eu­karyotes, for ex­ample bio­chemists, oc­ca­sio­nal­ly quip­ped that bac­ter­ia were noth­ing more than a bag of en­zymes. Well, from the per­spec­tive of bac­ter­ia, one could easi­ly re­turn the com­pli­ment: eu­kar­y­o­tes, for ex­ample single-cel­led amoe­bae, are little more than a... Read more →

Is Pseudomonas aeruginosa ubiquitous?

by Roberto
Going back several decades I tried to argue that, contrary to po­pular belief, Pseudomonas aeruginosa is not a ubiquitous bac­terium. This was based on our difficulties in obtaining strains from pristine environments, conversations with many colleagues de­scribing similar experiences, and... Read more →

Ice Ice Maybe

by Janie
The ability to trigger ice formation is a property shared by certain particles both organic and inorganic, including bacteria, viruses, phytoplankton, pollen, soot, dust. These little particles help water molecules come together and form ice at warmer temperatures than freezing point... Read more →

Green Sloths and Robots

by Roberto
... in the case of red par­rot feath­ers the pig­ment has the ad­ded be­ne­fit of pro­tect­ing the plu­mage from bac­te­ri­al de­gra­da­tion. To­day I stay on the to­pic of ani­mal co­lor­a­tion by de­scrib­ing the pe­culi­ar pe­lage pig­ment of sloths. Exact­ly what con­sti­tutes an eye-catch­ing color is, of course, in the eye of the be­holder. Read more →

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 →

Thinking outside the rod (or coccus)

by Roberto
With kind per­mis­sion by the or­gan­i­zers, we re­pro­duce here an edit­ed tran­script of Ro­ber­to's talk (via live vi­deo) at the meet­ing on 'Ma­jor ideas in quan­ti­ta­tive mi­cro­bi­al phy­sio­lo­gy: Past, Pre­sent and Fu­ture', held in June this year in Køben­havn, Den­mark. Read more →

Magnificently long : Thiomargarita magnifica

by Christoph
Microbiologists study mi­crobes with mi­cro­scopes be­cause they are not vis­ible to the na­ked eye. Un­less they are. This was ex­act­ly the case for "Can­di­da­tus Thio­mar­ga­ri­ta mag­ni­fi­ca", de­scribed in a re­cent Bio­Rχiv pre­print by Vol­lard et al. (2022): "A cen­ti­me­ter-long bac­te­ri­um with DNA com­part..." (more about the se­cond part of the title... Read more →

Bacterial Range Expansion

by Davide Ciccarese
This image I cap­tured of a re­sult of mine re­minds me of how im­port­ant it is to keep one's mind open and let the re­sults speak for them­selves, even after mak­ing a mis­take. As part of my re­search I was con­duct­ing du­ring my PhD with Da­vid John­son and Dani Or, I was in­ter­est­ed in study­ing... Read more →

Otherlands' Tour of Microbes Through Prehistory

by Janie
"It is the crucial paradox at the heart of paleontology that practically all our information about life comes only from death." This line from Thomas Halliday's Otherlands, of course, refers to the fossil record. So, it stands to reason that the entire field of paleontology is contingent upon microbes... Read more →

How to Fine-Tune a Riboswitch

by Janie
It has the inklings of a lame biology joke, but in actuality has profound implications among microbial communities: What's the similarity between male moths and RNA? The answer is the ability to detect extremely specific compounds. Like male moths that can detect a single pheromone molecule... Read more →
