@PeterHald "tester absolut positiv for celluloid" lyder som om en masse nitrogrupper pludselig fik lov til at blive til kvælstofmolekyler. 💥

@FiJe @PeterHald Jeg synes hele konceptet med at give klip i studiekortet er fantastisk. Men det er måske også bare fordi jeg ikke længere har et.

@KorayKaratay @sterlingericsson TALENs and ZFNs are not RNA based, that's one of the big advantages CRISPR has over them. Instead of having to engineer a protein to bind to a specific nucleic acid sequence, CRISPR is just directed by a guide RNA whose sequence is complementary to the target.

@PeterHald Når det nye semester starter, og Molekylærbiologi avler bananfluer...

@ChristosArgyrop @nanopore I feel like that would have fit better in the Chemical Biology journal than just straight Chemistry. Anyway, always great to see more ways to target RNA.

@Alon @anderspuck Tungsten is actually not too too bad. But everyone knows about the health hazards of lead - and it's the main element in most bullets. Those are being fired off a heck of a lot more than kinetic penetrators containing either tungsten or DU.

@freemo According to the list, two were partially gold. There is also a risk of survivorship bias, as gold would be a target for thieves, looters etc.

Our guy @anderspuck has just uploaded a video with his take of the Kakhovka dam explosion.

@jkbecker @timkmak Making the regular army look bad, that is. Wagner and the Russian army are rivals competing for much of the same resources.

@PeterHald 30% er okay heftigt. Den 37% man bruger i lab er rimelig træls at være i nærheden af med åbent låg, og højere koncentrationer bruges vist sjældent fordi det ekstra HCl bare bobler ud af opløsningen på nul komma fem.

Interesting analysis of manuscript retraction data, 2010-12 vs 2017-19:
-Increase in # of retracted papers
-Change in geographical origins.

😬

Data in figures shows groups of urban areas between which at least 2 retracted articles were co-authored.

Tid at fortsætte min #nørdetgråd om #husholdningskemikalier
Syrerne:

Eddikesyre er en svag syre, og "eddike" er en cirka 5% eddikesyreopløsning med en masse urenheder. Ren eddikesyre smager bare surt, så urenhederne har den væsentlige rolle at tilføje noget smag og sjæl.

Eddike dannes når eddikesyrebakterier spiser alkoholen i vin, cider og lignende.
De billigere varianter er industrieddike tilsat farve og smagsstoffer.

Bruges i mad, som bananfluelokkemad og som mild afkalker.

@PeterHald Jeg synes også citronsyre er mere effektivt til afkalkning end edikkesyre.

Måske langt hen ad vejen fordi det man køber tit er mere koncentreret, men det er også en stærkere syre.

Glæder mig til (at høre om) de organiske opløsningsmidler.

Dansk politik, krigen i Ukraine. 

@pmakholm Jeg tror snarere det handler om at de bare vil have så meget grænsekontrol som muligt af andre årsager (brun mand farlig), og det her bare er det seneste nemme påskud.

@PeterHald Den er da klar til at erstatte efeuen på Statsbiblioteket om en uge eller to. 😲

@ajkohn @ct_bergstrom He already did something similar with the model names of Tesla cars: S3XY

We're lucky to have been chose to beta-test the new SQK-RNA004 direct #rnaseq kit by oxford #nanopore, which promises better yields and accuracy than the RNA002 kit that has been around since 2018.
First 'burn-in' test on human poly(A) #RNA is looking quite promising

@Martinalexsmith Any improvements to base modification detection, or is that all on the software side?
