Day 11 #SciArtSeptember prompt venomous: my linocut of a Portuguese Man o’ War floating at the surface of the sea. 🧪🐡 These are beautiful but deadly creatures, also known as bluebottles, resemble jellyfish but are actually colonial organisms called siphonophores. They are made up of many 🧵
My Portuguese man o’ war linocut is printed in blues, turquoise, violet and pink on white 9.25” by 12.5” Japanese kozo (or mulberry) paper. The float is above the water surface, the tentacles below.

10 - Tawny My participation in #SciArtSeptember has been a bit sporadic - chronic illness is messing with me. But here is one of my favourite animals, the Tawny Owl. Love to hear them calling to each other 🤎

What do bacterial cells do when they run out of nutrients? Although most bacterial studies focus on cells in exponentially growing states, in the wild bacteria likely spend most of their time slowly starving to death. 1/n www.biorxiv.org/content/10.1...
biorxiv.org
E. coli prepares for starvation by dramatically remodeling its proteome in the first hours after loss of nutrients
It is widely believed that due to nutrient limitations in natural environments, bacteria spend most of their life in non-growing states. However, very little is known about how bacteria change their p...

"Women are less likely to be named authors on any given document in all fields and at all career stages." "Women are credited less in science than men" Nature 608, p 135–145 (2022) Link: www.nature.com/articles/s41...
Graphs plot the probability that a potential author on a scientific document (article or patent) is a woman against the probability that an actual author is a woman. A potential author is defined as an employee in a laboratory between 2013 and 2016 from which an article or patent was published between 2014 and 2016. There are 17,929,271 potential article authorships and 3,203,831 potential patent inventorships in our sample. The markers in each panel are sized by the total number of actual authorships in the category. The diagonal represents parity in the gender composition of potential and actual authorships. Individual data on potential and actual authorships are shown in Supplementary Fig.  5. Left, disparity across job titles. Right, disparity across research fields. Observations are weighted by the inverse of the number of teams per employee times the inverse of the number of potential articles or patents per employee.

New from the lab. We were stuck studying plasmid mobility because we ignored most origins of transfer by conjugation. Using the occurrences of known oriT, we developed a method to find novel unrelated families. Works well. We now cover most conjugative plasmids of E coli, K pneumo & A baumannii.
