Can cells remember being starved, and does that memory change how they behave in the future? This fundamental biological question is investigated by the research project called "Total Recall". It's funded with 40 million NOK through the "Toppforskere" programme from the Research Council of Norway

Genome sequencing & single-cell transcriptomics continue to produce findings that challenge the idea that #cancer is purely a genetic disease. This Essay delves into #omics data that questions the somatic mutation theory & presents alternative theories based on GRNs & tissue fields.🧪 plos.io/3DRtAEW
A figure depicting the concept of cancer attractor states within Waddington's landscape, and how gene regulatory network dynamics influence these states. The figure shows how cancerous cells derive from those that have accidentally entered into unused attractor states that are usually unoccupied in developmental trajectories.

Instead of listing my publications, as the year draws to an end, I want to shine the spotlight on the commonplace assumption that productivity must always increase. Good research is disruptive and thinking time is central to high quality scholarship and necessary for disruptive research.
