isn't this slip not quite common among mycologists? 😎

christoph: just popped up in my memory that the above video wasn't in the supplement of their paper but could be downloaded from the website of the lab www.k2.phys.waseda.ac.jp and the download links of the movies are still there 🙂 www.k2.phys.waseda.ac.jp/Movies.html

christoph: me too. can't get the elegant (schick) shape of 𝘙𝘶𝘨𝘰𝘴𝘪𝘵𝘢𝘭𝘦𝘢 𝘰𝘳𝘺𝘻𝘢𝘦 out of my mind...
but lacking stock of fusilli/rotini, I resorted to ravioli instead 😋

can you imagine any similarity to the (E. coli) SecYEG translocon + SRP pathway?

christoph: great paper! blew my mind when I first read it. one of the first occasions when I realized that videos genuinly belong in scientific publications. (we had it in 2014 in STC in the 'Pictures Considered' series.)

ribosomologists take note 👇

archaeal ribosome hibernation factors aRDF, Dri, ...and now: Hib (see ALT)
#Archaea #ArchaeaSky
c. Hib 3D structure. The N-terminal domain of Hib (1-269) is made up of four CBS domains. Two CBS domains
interacts through their beta-sheets to form a bateman module. Two bateman modules interact to form a disk-like
structure defined as parallel CBS module in51. Each CBS domain consists of three-standed (two parallel and one
anti-parallel) b-sheet with two a-helices52. In domains 2,3 and four the first beta strand is less well defined and
extended, as already mentionned in other CBS-domain containing structures. One long loop is inserted between
a8 and b10 of the third CBS domain. The C-terminal domain (272-387) has the babbba topology found in all
bacterial HPF/RaiA-like structures. The five last residues are not visible in the cryo-EM map.

christoph: this 👇 is how I like to prepare gnocchi al gorgonzola: with lots of prezzemolo, panna da cucina in 1:2 ratio with gorgonzola, parmigiano grattugiato (more details in the cookbook I wrote for my son)

christoph: my personal favourite is gorgonzola, gorgonzola dolce 👇 to be precise. this cheese – also made by 𝘗𝘦𝘯𝘪𝘤𝘪𝘭𝘭𝘪𝘶𝘮 spp. – usually comes with a "blond" rind

christoph: the cabrales cheese they make in asturias, spain, has when ripe a phenotype described as:

"Soft, thin, creamy rind of gray color with yellow-reddish areas." (ref. in ALT)

apparently, the 𝘗𝘦𝘯𝘪𝘤𝘪𝘭𝘭𝘪𝘶𝘮 spp. responsible has been with the cheesemakers for quite a while...

christoph: nothing wrong with 'aqualung', but they got me with 'bourée' from their 1st album (from '69 👀)

the plot thickens 👇 as we all suspected and feared(?), organellogenesis is not straightforward, but rather, well,... a thicket ¯\_(ツ)_/¯

christoph: since long I consider the shape of 𝘚𝘵𝘦𝘭𝘭𝘢 𝘩𝘶𝘮𝘰𝘴𝘢 especially schick, but there are so few images around that I'm not really sure about their morphology.
the other day I found 𝘙𝘶𝘨𝘰𝘴𝘪𝘵𝘢𝘭𝘦𝘢 𝘰𝘳𝘺𝘻𝘢𝘦 YC6860^T, and we can dispute whether they're fusilli or rotini 😋 (🙋‍♂️ pasta addict)
