Rate bit of good news. Just enough to slip a sliver of hope in these trying times.

Thankfully there should be a spider size limit to trip these off. No Aussie-sized Huntsman arachnids prowling ceilings…or so I hope. 🕷️🕷️🕷️

Philip nicely summarizes recent findings from Sebé-Pedrós and colleagues that the origin of multicellular life may come down to extrusions of DNA topology, juxtaposing far-flung genomic regions in the spatiotemporal regulation of gene expression.

I adored writing this piece. It brings together several of the things preoccupying me right now, like chromatin organization and gene regulation. There's so much more to be said on that. Also, these marine critters look gorgeous.

New work shows that physical folding of the genome to control genes located far away may have been an early evolutionary development.

Condolences to your community and Professor Gurdon’s family. A remarkable scientific talent, who enriched the developmental biology community not only in the UK, but worldwide.

Quite the start for John Maynard-Smiths classic little book: “Shaping Life: Genes, Embryos, and Evolution”. #DevBio

Tunneling nanotubes connecting neuronal dendrites in mammalian brains pass ions, allowing propagation of electrical signals in networked clusters of neurons. Also large enough to pass proteins like beta-amyloid, possible mechanism for spread of neurodegeneration.

Neurons can communicate via hidden network of nanotubes, study finds

Tubes in mouse and human brains may also influence spread of brain disease

Very sad news, John Gurdon has died.

A developmental biologist's developmental biologist, Nobel prize winner

His work is the foundation of much of today's dev & stem cell bio.

An inspiration to many, including me. Always asking questions & wanting the answers

Glad to post our latest preprint, led by former graduate student Sam Moore, with help from Danielle Stanton-Turcotte, Karolynn Hsu, and Emily Witt. We found a surprising role for Mllt11 in hippocampal neurogenesis by controlling radial glial progenitor differentiation to transit amplifiers. #DevBio

Impaired subgranular zone radial glia morphology and transient amplification of neural progenitors in Mllt11-deficient mice leads to increased hippocampal neurogenesis

The mammalian hippocampus derives from the cortical hem region of the forebrain and is one of the two regions in the mammalian forebrain that contains neural progenitors capable of generating new neur...
