The server that the Node runs on is going to receive some general maintenance between 6:30 PM UK time tonight and early tomorrow morning. This may affect our visitors in North America (and the early risers at the other end of the Pacific) so please be patient if anything seems to not be working during[…]

New format for job postings You may have noticed some job ads for postdocs appearing on the Node. Until today, these ads appeared with the rest of the posts, but we now changed how job ads are displayed on the Node, to make them stand out from the rest of the content. This makes it[…]

Here are the research highlights from the current issue of Development: Nr5a receptors reset EpiSC pluripotency Rodent embryonic stem (ES) cells that are derived from blastocysts self-renew without mitogenic growth factors and robustly colonize chimaeras, whereas egg cylinder-derived stem cells (EpiSCs) require fibroblast growth factor and contribute poorly to chimaeras. Nevertheless, expression of a single[…]

Recently a paper in Science caught my attention since its title combines the words mitotic recombination with patients and Ichthyosis. Having worked with Drosophila during my PhD and now being in a vertebrate lab, I’m well aware of the existence of tools to induce mitotic recombination to generate somatic clones of mutant cells in certain[…]

“Why are there no pop hits about Arabidopsis?” sings Karmadillo. Even though their Arabidopsis song is not a pop hit (yet?) either, Karmadillo can at least lay claim to the honour of having performed it alongside other science-themed songs on the “Reproductive Stage” at the virtual 2010 Geek Pop festival. The song celebrates Arabidopsis as[…]

by Valerie Butler Most of us, I’m sure, can remember that AHA moment in school when we realized that science is pretty cool. Imagine how it might be for a student enrolled in a school lacking the resources to teach science well, or who was never given the opportunity to excel in anything, let alone[…]

In a paper published today in Cell, Detlev Arendt, Raju Tomer and colleagues reveal evidence that the cerebral cortex evolved much earlier than previously believed. Using a new technique to detect and image simultaneously expressed genes in a compact brain area, they discovered that the gene expression patterns in the olfactory processing region (mushroom bodies)[…]

“You’re probably wondering why I’m here”, were the first words of Edward Marcotte’s talk at the SDB meeting last month. After all, he was about to speak about systems biology in a session on organogenesis. What followed was not only a new way to identify genes involved in developmental processes, but also a perfect example[…]

Many human embryonic stem cell (hESC) researchers are now scrambling for funding and concerned about the future of their research, following a recent ruling in the United States by Chief Judge Royce C. Lamberth. To understand this ruling, both how it came about and its implications moving forward, it’s important to take a look at[…]
