Lost & Found #3

by Christoph

If you want to leave 𝕏 (for­merly Twit­ter) for any rea­son, you can de­ac­ti­vate or com­pletely delete your ac­count. That's it then. But if you want to take a few still in­ter­est­ing book­marks with you when you move out, well, then the 𝕏o­dus takes a lit­tle longer. Here are three more of these sal­vaged book­marks, in Lost & Found #3.

Book­mark #1

"FtsK is a dou­ble-stranded DNA translo­case, a mo­tor that con­verts the chem­i­cal en­ergy of bind­ing and hy­drolysing ATP into move­ment of a DNA sub­strate. It moves DNA at an amaz­ing rate – >5,000 bp per sec­ond – and is pow­er­ful enough to re­move other pro­teins from the DNA" (ref.). If you want/need to know more about the role of FtsK in chro­mo­some seg­re­ga­tion and cell di­vi­sion in bac­te­ria, please re­fer to Fig­ure 2 and the leg­end in this pa­per (Open Ac­cess) by Mar­tin Thanbich­ler. The tweet by James Wagstaff was based on a preprint and has since been pub­lished.

Book­mark #2

In 2021, the de­voted "phage hunter" Alexan­der Harms (@aharms485.bsky.social) and his co­workers pub­lished the BASEL phage col­lec­tion. Work on the fol­low-up was al­ready in full swing at the time, and a preprint has just been pub­lished, but it does not in­clude the photo of a typ­i­cal plaque as­say shown here. It must have stayed in the lab jour­nal – and, for­tu­nately, found its way onto 𝕏.

Book­mark #3

As Jan-Willem Veen­ing (@jwveening.bsky.social) says in his tweet: Cool movie alert! For a mi­cro­scopist, there is hardly any­thing more sat­is­fy­ing than pa­tiently ob­serv­ing how a grow­ing bac­te­r­ial pop­u­la­tion grad­u­ally be­comes het­ero­ge­neous (here "red" and "green"). Un­for­tu­nately, only still pho­tographs can be shown in printed pub­li­cations, and these have, even when arranged as a time­line, con­siderably less charm than a movie. Note that the 16 frames in the movie were ac­tu­ally taken over a pe­riod of 280 min (Fig­ure 5F). This tweet was based on a preprint and has since been pub­lished.

  • Search­ing for ΦX174

    The search for ΦX174 was the task that our fel­low blog­ger ‪na­ture­poker‬ set him­self some time ago. His search was not in some largely for­got­ten and iced-over box in the back cor­ner of a –80°C freezer. In­stead, he searched the lit­er­a­ture as to when and where this bac­te­rio­phage was first de­scribed. Na­ture­poker has recorded the re­sult of this sleuthing...

    by Elio — Prof. Saly­ers' con­tri­bu­tions to mi­cro­bi­ol­ogy as well as the qual­ity of her teach­ing are widely known and much ad­mired. Her lab pro­vided im­por­tant tools for the ge­netic dis­sec­tion of Bac­te­ri­odes and its me­tab­o­lism of com­plex car­bo­hy­drates. More broadly, she pointed to the im­por­tance of the hu­man mi­cro­biome well be­fore it…

    by Elio — The mys­tery of al­co­holic fer­men­ta­tions was un­cov­ered in the first half of the 19th cen­tury by Cagniard-La­tour (1837) in France, and Schwann (1837) and Kütz­ing (1837) in Ger­many, based on mi­cro­scopic stud­ies but not with­out con­tro­versy. The great Ger­man or­ganic chemist Jus­tus Liebig did not like the idea that al­co­holic…

    by Elio — Five years and over 500 posts be­hind us, I would like to share with you a bit of the his­tory of this blog. How did it start? I had re­tired of­fi­cially in 1995 from Tufts Uni­ver­sity in Boston and came to San Diego. I ar­rived with the in­ten­tion of stay­ing in­volved in…

  • An­drew Wright (1935−2023)

    by Roberto — This past Oc­to­ber 9th, mi­cro­bi­ol­ogy lost an ex­tra­or­di­nary mem­ber when An­drew Wright died. Those of us for­tu­nate to have in­ter­acted with him over the years lost a very good friend. Even on a first meet­ing it was im­pos­si­ble not to sense his kind­ness and gen­uine in­ter­est in the con­ver­sa­tion, un­der­scored by his gen­tle smile and an en­dear­ing Scot­tish ac­cent.
