A Brain Biopsy From a Blood Draw?
Here is a thought experiment that, until recently, belonged firmly in science fiction. You go to the doctor, give a small vial of blood, and a computer hands back a detailed molecular portrait of what is happening inside your brain. Not a scan, not a guess from symptoms, but a simulated readout of which genes are active in which cells, deep in tissue no needle will ever safely reach. This week a San Francisco company said it is building exactly that. Verge Labs, which until now went by Verge Genomics, relaunched as what it calls a frontier AI lab for human disease biology. The centerpiece of the pitch is a phrase worth sitting with: the virtual biopsy. The problem they are aiming at Start with a sobering statistic that drives the whole effort. Roughly nine out of ten drug trials fail. The most common reason is not that the drug is useless in some absolute sense, but that the wrong target was tested in the wrong patients. We intervene on a mechanism that turns out not to matter ...
