From the Aegean Bronze Age, Minoan clay vessels with black handpainted decoration.on a pale biscuity-coloured slip Top left - clay flask decorated in Minoan ‘Marine Style’’ with an octopus with tentacles writhing around the body of the vase. Additional motifs such as seaweed and rocks represent the seabed. From Palaikastro, 1500-1450 BC Top right - clay rhyton in the shape of a bull’s head. A rhyton is a type of pouring vessel used for filling cups or making liquid offerings. There is a pouring hole at the bull’s mouth. From Knossos Little Palace, 1450-1375 BC Bottom left - Nautilus vessel - clay rhyton depicting the seabed with nautili, corals and seaweed. From Phaistos Palace, 1500-1450 BC Bottom right - Basket shaped rhyton decorated with double-axe motif. There is a small pouring hole in one of the bottom corners. From Pseira, 1500-1450 BC

Marvellous Minoan clay vessels made by creative potters on the island of Crete during the Aegean Bronze Age around 3,500 years ago! 🤩

Horizontal gene transfer of the functional archaellum machinery to Bacteria Motility in Archaea is driven by a nanomachinery called the archaellum. So far, archaella have been exclusively described for the archaeal domain; however, a recent study reported the presence of arch...

Would you expect that Bacteria use an archaellum for swimming? We didn't, but we found that some Chloroflexota do! Find the story here: www.biorxiv.org/content/10.1...

Study design to capture the dynamic nature of early microbiome and brain development. (A) Study design; participants (N = 194) were seen up to three times over the first 18 months of life. Stool samples and EEG data were collected, generating microbial functional profiles (stool) and VEP waveforms (EEG) used in subsequent analyses. Analyses included generalized linear models (GLM) and feature set enrichment analysis (FSEA). (B) Longitudinal sampling of study participants; density plots (top) for stool and EEG collection show the ages represented in each visit. The scatter plot (bottom) shows individual participant visits. Dotted lines connect separate visits for the same participant. When stool and EEG data were collected for the same visit (purple) but not on the same day, the dot represents the median age of collection, and vertical bars in blue and red represent stool and EEG collections, respectively.

Leveraging longitudinal data from 194 infants across the first 18 months of life, researchers show that microbial genes encoding neuroactive compounds are associated with visual cortical neurodevelopment. Read the article in #mBio: asm.social/2uo

Model for the interaction between P. aeruginosa and K. pneumoniae. These bacteria can co-exist in nutrient-replete conditions. Under iron-limiting conditions, siderophore synthesis is induced in both bacteria. Iron limitation can also turn on the synthesis of biosurfactants, rhamnolipids, in P. aeruginosa, allowing it to push away K. pneumoniae.

#MicrobiologyMonday: Pseudomonas aeruginosa releases a surfactant that displaces Klebsiella pneumoniae from solid surfaces. By pushing K. pneumoniae away, the detergent allows P. aeruginosa to better compete for limited iron. Learn more in #mBio: asm.social/2sH
