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.
Beautiful #cryoem structure → elegant model for FtsK DNA pumping from Nicolas Jean in the Löwe group. Read all about it: https://t.co/tU1yifV2yJ pic.twitter.com/0AY4dPuODW

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.
Fun observation of the day: The virulent phage in the second lane clears the turbid plaques of the phages in the adjacent lanes. I suspect very potent secreted lysins 🤔🧫.

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.
Cool movie alert! Checkout our latest preprint in which we built, for the first time, synthetic gene regulatory networks in Streptococcus pneumoniae including toggle switches! https://t.co/75X5GfH1Zx pic.twitter.com/DX8eP0U7V7
