    What fraction of cellular DNA turnover becomes cfDNA?

    Ron Sender, Elad Noor ... Yuval Dor
    Comparing tissue-specific plasma cfDNA concentration with cellular turnover rates reveals that less than 10% of dying cells' DNA reaches plasma, highlighting significant local clearance mechanisms and suggesitng approaches to enhance liquid biopsy sensitivity.

    How microscopic epistasis and clonal interference shape the fitness trajectory in a spin glass model of microbial long-term evolution

    Nicholas M Boffi, Yipei Guo ... Ariel Amir
    High-resolution simulations of evolving microbial populations reveal that microscopic epistasis slows the rate of adaptation, while clonal interference can either speed it up or leave it fixed.
