Isso poderia ser The Tomorrow Code , de Brian Falkner?
Esta revisão menciona vários dos temas que você discutiu.
Take a look at a few of the major sci-fi themes discussed: analyzing data from background gamma ray radiation detectors for messages sent backwards in time, macrophages, gene splices spiraling out of control, personal submarines, genetic codes for our destruction living in our own genes, time loops and causality, and more. In fact, if the protagonists hadn’t been kids, I’d argue this was a pretty ambitious novel all by itself.
