Here are some articles that look especially interesting on stem cells, cancer, and CRISPR. I was just at the SNO meeting in SFO on childhood brain tumors so those are on my mind more. Childhood cerebellar tumours mirror conserved fetal transcriptional programs (Nature) Childhood brain tumors “think” they are building organds in fetuses. H3.3 K27M depletion increases differentiation and extends latency of diffuse intrinsic pontine glioma growth in vivo. (Acta Neuropathologica) from Suzy Baker-led team. H3K27M induces defective chromatin spread of PRC2-mediated repressive H3K27me2/me3 and …Read More

This potential future, radical application of “gene editing” is now often colloquially referred to as “CRISPR babies”. Read that piece for the reasons behind my thinking and the risks involved in leaving the door open to using CRISPR to make people. Of course, this was …Read More

My daughter Julie and I have written a book together entitled,  “How to Build a Dragon or Die Trying, A satirical look at cutting edge science.” The book will be out sometime in June most likely. This is a very different kind of book than my first two, Stem Cells: An Insider’s Guide and GMO Sapiens. In How to Build a Dragon we, first of all, take a satirical tone as highlighted by the subtitle. We are somewhat poking fun at science hype in …Read More

The first article doesn’t really fit into the other main categories, but the title “herding brains” caught my eye. Stem Cells Stem cells and regenerative capacity in aging brain, article in Cell. Quiescence Modulates Stem Cell Maintenance and Regenerative Capacity in the Aging Brain. Does this kind of research have relevance to humans? See interesting, complex graphical abstract …Read More
