    Como país, necesitamos que nuestro talento investigador retorne: @IYImeeting. ¿Cómo? 1) figura de investigador con contrato indefinido en el SUG, 2) agencia de investigación gallega pública e independiente, 3) financiación estable del 2+% del PIB gallego. https://www.farodevigo.es/gran-vigo/2022/12/28/jovenes-investigadores-gallegos-diaspora-reclaman-80433690.html

    Together with our CONET, which is a model for copy number evolution in cancer, and was also out recently in @GenomeBiology (10.1186/s13059-022-02693-z), SIEVE makes a perfect duet for analyzing single tumor cell DNA-seq! With @senbai_kang and @MagdaMarkowska6 https://twitter.com/GenomeBiology/status/1600872221781663744

    Genome Biology @GenomeBiology

    SIEVE, a single-cell evolution explorer, fro @senbai_kang, @ewa_szczurek & co, uses single-cell DNA sequencing to infer somatic variants and cell phylogeny. It corrects branch lengths for acquisition bias, and can discern single and double mutants
