Development: New Executive Editor

Posted by on November 30th, 2011

I’m the new Executive Editor at Development, taking over after Jane Alfred’s eight years at the journal, and I’d like to take this opportunity to introduce myself. I’m starting here fresh off the plane from Heidelberg, Germany, where I have been working as a scientific editor at The EMBO Journal for the last three years,[…]

Posted by on November 30th, 2011

What was new on the Node this month? Here are a few of the highlights from November: New Research: Several exciting new research papers were discussed on the Node this month. In one post, Stas Shvartsman introduces a recent Development paper from his own lab that describes a method to quantify the spatial range of[…]

December desktop calendar

Posted by on November 29th, 2011

And here it is: the last of the desktop wallpaper calendars. In June we celebrated our first birthday, and decided to give all our readers a virtual gift. It ended up being six gifts: one desktop calendar wallpaper for each remaining month of 2011. If you want to see all the images, or download the[…]

Book review: Fast-forward: the fourth dimension in development

Posted by on November 23rd, 2011

Development issue 24 features several book reviews. Over the next few weeks, these book reviews will also appear here on the Node. In this first one, Elaine Dzierzak and Catherine Robin compare developmental biology to Star Trek in their review of “Imaging in Developmental Biology: A Laboratory Manual” (Edited by James Sharp and Rachel O.[…]

Spatial range of a morphogen gradient

Posted by on November 23rd, 2011

Estimating the range of a morphogen gradient Morphogen gradient, defined as a concentration field of a chemical factor that acts as a dose-dependent regulator of cell differentiation, is an established concept in developmental biology. However, morphogen gradients in real systems are difficult to measure and mechanisms by which they control patterns of cell fates are[…]

In Development this week (Vol. 138, Issue 24)

Posted by on November 22nd, 2011

Here are the research highlights from the current issue of Development: Getting to the heart of Flk1 expression The Flk1 gene, which encodes a VEGF-A receptor, is expressed in the multipotent mesodermal progenitor cells of mouse embryos that give rise to various haemato-cardiovascular cell lineages. FLK1 expression also marks haemato-cardiovascular cell lineages in differentiating human[…]

Doing Science in Barcelona

Posted by on November 22nd, 2011

Blog entry When thinking Barcelona, what first comes to mind is probably the football and Olympic games, the beaches, relaxed Mediterranean lifestyle, siesta and long nights out. All of it is accompanied with the Gaudi’s whimsical architecture at the background as an extra bonus. People usually go to Barcelona for a vacation or … for[…]

Stand With Science

Posted by on November 21st, 2011

A group of graduate students at MIT have written a letter on behalf of American graduate students, urging the United States Congress not to cut science funding. The Congress Joint Select ‘super’ Committee on Deficit Reduction will make their decision later this week, and today is the last day to sign the letter. If you’re[…]

PHD Comics on the big screen

Posted by on November 17th, 2011

The web comic Piled Higher and Deeper (PHD) has been commiserating with graduate students since 1997. And now you can watch the comics come to live on the big screen, as universities and institutes across the world (including Antarctica!) are screening the PHD movie. Fans of the comic will recognize most of the jokes, but[…]

Further strides in ES cell organogenesis

Posted by on November 13th, 2011

A new Nature study has again demonstrated the power of ES cells as a model system for recapitulating developmental processes in vitro. Following on from the amazing self-assembly of differentiated optic-cups reported earlier this year, Yoshiki Sasai’s latest work has resulted in the generation of functional pituitary gland tissue from mouse ES cells. Using a[…]
