Commitment to Biofilm Formation
Noteworthy — Pseudomonas aeruginosa start biofilm formation using mechanosensitive appendages.

City, Biofilm of Humans (Part II)
by Roberto — You have the privilege of orbiting Earth aboard the International Space Station. As nighttime darkness envelopes a cloudless Europe, your attention is drawn to your favorite city in the world, the "City of Lights." Paris. From your vantage point, some 400 km above the surface...

City, Biofilm of Humans (Part I)
by Roberto — The title of today's post is a twist on the opinion article Paula Watnick and I wrote at the turn of the century: Biofilm, City of Microbes. As I contemplate population dynamics, from bacteria to humans, I am increasingly convinced that human cities and microbial biofilms manifest some similar attributes.

Wait, What? extracurricular DNA (eDNA)
by Christoph — Among biologists, DNA is a household term, the acronym for desoxyribonucleic acid, which hardly anyone pronounces in full. But can you find your way around the zoo of prefixes that are in use and in most cases are not separated from 'DNA' by a hyphen, as for example in Z‑DNA? cccDNA, rcDNA...

...rosette is a rosette. (3|3)
by Christoph — Among the Alphaproteobacteria, a number of species from phylogenetically distantly related orders are known for forming rosettes during growth. Despite commonalities, they all have their own peculiarities when it comes to the first cell‑cell contact(s) during "rosetting". Phaeobacter inhibens (order Rhodobacterales) cells attach to each other by their "sticky ends" at one pole...

by Christoph — I like to imagine that microscopists in the late 19th century who looked at water samples were happily surprised when they saw organized structures of cell clusters in the whole tangle of protists and bacteria, which they then liked to call "rosettes" because these were structures known from botany. And on closer inspection, it turned out that some of them were actually bacterial rosettes…
