AnniZLab: [🦠, 🧬 , ✨]

And it didn't stop when the balance reached 0 (already $-300)! 🧪🧬🖥️✨

Hi everyone, heads up that openAI API monthly limits appear to not work! We got an email that our jobs passed the limit and they're still going (already $900 with a $400 limit). gpt-5_1 also costs more than we expected - need more real-time math!

In remembrance of Peer Bork  | EMBL EMBL and its community are deeply saddened by the death of Peer Bork, the organisation’s Interim Director General.

very sad news. Peer Bork was one of the leaders of our field, a wonderful scientist, and he's much too young to be gone. www.embl.org/news/embl-an...

Après-Ski scientific sessions from 16:00 till very late.

For many years, Peer Bork organised Bio-IT retreats to bring together the bioinformaticians across EMBL, in Garmisch-Partenkirchen and later Feldberg. Days out on the mountain followed by forward-looking and meta-science oriented sessions in the hut that fueled many projects and careers.

So happy to host Dr. Xiaoqian (Annie) Yu - soon starting her lab at University of Montreal! She used population genomics and large data analysis to group gut microbiome into ecological units based on sweep events (major revision at Nature)!

Structure and specificity of the colibactin-DNA interstrand cross-link. Characterization of DNA damage by the human gut bacterial genotoxin colibactin reveals a preference for alkylation at AT-rich DNA sequences and the importance of an unstable central α-ketoimine in mediating this specificity. These results help to explain the locations of cancer-linked mutations derived from colibactin exposure.

Bile acids target at STING dimer-dimer interface. (a) HEK293T transfected with pMSCV-hygro-STING were treated with DCA-4 (10 µM) in presence of different concentrations of NVS-STG2 for 30 mins at 37 °C, followed by 365-nm light irradiation. The labeled proteins in cell lysis were reacted with az-biotin and enriched with streptavidin beads (‘pulldown’). Equal loading was validated by immunoblotting of input samples before enrichment (‘input’). (b) Quantification of binding efficiency in A by grayscale analysis (pull down/input) (n = 5 - 6 biologically independent samples.). Data were analyzed by unpaired two-sided t-test. (c) High-resolution cryo-EM map of the two STING dimer with highlight of dimer-dimer interfac molecular density. (d-f) HEK293T transfected with pMSCV-hygro-STING (WT and mutations), IFN-Beta_pGL3 and pRL-TK control plasmid were treated with diABZI (20 nM) in presence or absence of DCA (n = 5 biologically independent samples). A two-way ANOVA followed by Sidak’s multiple comparisons test was used to calculate adjusted P values. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001.

Thanks!

Also, our seq alignment tool Mapper can infer ancestor references and reduce the penalty for a basepair mismatching a ref but matching its ancestor.

The main idea is about using phylogeny to give feedback to users about which parts of the reference tree lack important genomes.

A secondary idea is that our seq alignment tool Mapper can infer ancestor references and reduce the penalty for a basepair mismatching a ref but matching its ancestor.

YAY this tool might be able to use that information to give feedback about which part of the reference tree lack important genomes!

YAY thanks! maybe we can even choose several least bad references and/or a pangenome.

Reference genome choice compromises population genetic analyses - a problem for microbes too! Our lab is designing a tool to automatically choose references for input samples using features like phylogeny of reads to existing references. Any thoughts🤩? 🧪🦠🧬🖥️ #microsky

That's awesome - will share with my people :) Thank you, Sean!

Using leave-one-out cross-validation to calculate metrics such as AUC and R^2 creates bias! This can be fixed by removing one of each class in the meanwhile to maintain the training data distribution - great work by Tal and his team 🧪🧬🖥️
