Frustrated by noisy CITE-seq data?
ADTNorm helps normalize it and introduces a staining index to assess antibody quality.

Great work by former postdoc Ye Zheng. Supported by @hipcproject.bsky.social

1 Genomic Test Can Diagnose Nearly Any Infection A decade-long effort has resulted in a new, rapid genomic test to diagnose rare infectious diseases in the brain and lungs.

Very cool! One genomic test can diagnose nearly any infection! Comes out of the lab of Charles Chiu @ucsfhealth.bsky.social

@lpachter.bsky.social Interesting! Also, Louvain/Leiden determine the number of clusters automatically (through the resolution), often leading users to assume the default is optimal! However, identifying the correct number of clusters is a complex statistical problem, which shouldn't be ignored.
