Brazil: origins, evolution and future of DevBio in the country of the 2014 World Cup

An inspiration

Posted by on August 11th, 2014

I write this article in the beautiful city of Vienna at the European Society for Evolutionary Developmental Biology meeting 2014. This is a meeting that happens every two years and I have been to every single one since the inaugural meeting in 2006 in Prague. As a card-carrying evolutionary developmental biologist, I began my career […]

Out with the old, in with the new: reassessing morpholino knockdowns in light of genome editing technology

Posted by on August 6th, 2014

This Spotlight article was written by Stefan Schulte-Merker and Didier Y. R. Stainier, and was first published in Development.   Morpholino oligomers have been used widely and for many years in the zebrafish community to transiently knock down the function of target genes. It has often been difficult, however, to reliably discriminate between specific and non-specific effects, and thus generally accepted guidelines […]

A consideration of mammalian dermal evolution.

Posted by on August 2nd, 2014

  Hello everyone. My background is in systems engineering, and i have over forty years experience of building and trouble shooting mechanical/hydraulic systems. I have an interest in the evolution and function of biological systems, hence my involvement in this. I have no issues with the genetic basis of biology, but i am pretty sure […]

Your non-model organism is going extinct

Posted by on July 17th, 2014

“There is no such thing as a non-model organism” R. Behringer This bold statement was announced less than a week into our Embryology course and has left a lasting impression on lecturers and students alike. At first it seemed like a sympathetic statement to the extensive and diverse systems us students were arriving from… “yeah, […]

Brazil: origins, evolution and future of DevBio in the country of the 2014 World Cup

Posted by on July 13th, 2014

By Henrique Marques-Souza and Rodrigo Nunes da Fonseca   Widely known as the country of soccer, samba and beautiful beaches, one might wonder if it is possible to perform high quality research in Developmental Biology in Brazil with so many distractions. What are the pros and cons of doing research in this area in Brazil?  […]

Use it or Lose it: Insights on neuronal connections in the vertebrate retina

Posted by on May 18th, 2014

This is the final post from our developmental neurobiology seminar this semester. Two students wrote about our discussion of the importance of neuronal activity during synaptogenesis and their professor combined and edited the pieces. As usual, we focused  on development in the vertebrate retina. Hope you’ve enjoyed our contributions, we’ve enjoyed sharing our new-found understanding. […]

Open study hopes to put STAP in the past

Posted by on May 12th, 2014

This article is a re-post of an article published at the F1000Research blog on the 8th of May, 2014. Eva Amsen is the outreach director of F1000Research.     Many of you will have been following the STAP stem cell saga: In January, researchers from Japan announced in Nature that they had produced induced pluripotent stem cells (iPS cells) […]

Good guilt

Posted by on May 7th, 2014

Seán Mac Fhearraigh, from PostPostDoc, recently asked me to write a post about my experiences outside academia. Because I don’t have a lot of experience yet (I have only been working as the Node community manager for less than a year) I decided instead to focus on what I did during my PhD that helped the transition. […]

Exciting advances and scientific advice- the Node readers have their say!

Posted by on April 25th, 2014

Last month we attended the joint meeting of the British Society for Developmental Biology and the British Society for Cell Biology in Warwick. At the time we had the opportunity to chat with Node readers, and gather their thoughts on two different questions:   - What is the most exciting scientific advance of the last […]

Flippase recognition target: orientation matters, so why care?

Posted by on April 16th, 2014

FRT sites are used often (at least in Drosophila) for inducing deletions or “flipping out” of markers in transgenic constructs. When there are two FRTs sequences in tandem, after inducing flippase the DNA sequence that is between these two sites will be deleted. If two FRT sites are facing each other (or looking away), the […]
