Spider segmentation gets its SOX on!

Posted by on October 15th, 2018

There is a vast amount of information known about how some animals pattern their bodies into repeated segments, especially in the fruit-fly Drosophila melanogaster. However, when compared to other arthropods, there are several characteristics that are derived in the fruit fly. It has a very short development time, a syncytium at the blastoderm stage allowing[…]

Postdoc – The evolution of spiral cleavage

Posted by on October 4th, 2018

An ERC-funded Postdoctoral Research Assistant position is available at Queen Mary University of London in Dr José M (Chema) Martín-Durán’s group. The project focuses on the epigenetic regulation of conditional and autonomous development in spiral cleavage. Queen Mary is one of the top research-led universities in the UK and was ranked 9th among the UK[…]

A day in the life of a colonial tunicate laboratory

Posted by on August 28th, 2018

Have you heard of an animal that can lose most of its body tissues and the remnant tissues aggregate to regenerate the lost parts and recovery its original form? Do you know an animal that can quickly colonize marine surfaces by asexual reproduction, just like weed would in terrestrial environments ? Do you know an[…]

A day in the life of a Capitella teleta lab

Posted by on July 10th, 2018

It’s undoubtedly the middle of summer here in Saint Augustine, Florida. Daily temperatures are soaring into the 90s, and we’re grateful if the humidity dips below 70%. Thankfully, the Seaver lab doesn’t have to contend with much of this heat. Instead, our members are inside, comfortable though busier than ever, mentoring summer interns, piloting new[…]

Postdoctoral Positions — Neural crest stem cells, pigment pattern, adult form

Posted by on June 1st, 2018

Postdoctoral positions are available in the Parichy lab at University of Virginia. The lab studies development using zebrafish and related species. Current emphases include hormonal control over post-embryonic neural crest stem cells, plasticity in cell state, evolution of novel cell types, and mechanisms of pattern formation and cell–cell communication within zebrafish and across Danio species.[…]

Medaka fish sheds light on the evolutionary origin of vertebrate pair appendages

Posted by on April 23rd, 2018

Link to the paper: https://www.nature.com/articles/s41588-018-0080-5   The evolutionary history of vertebrate appendages Have you ever wondered how our hands and feet evolved? This question, which commonly evokes fish crawling from sea to land, has long been a subject of interest, both for palaeontologists and developmental biologists. Appendages are an important part of the tool kit[…]

Funded places for early-career researchers at a human brain development & evolution workshop

Posted by on March 8th, 2018

This summer, the Company of Biologists, the not-for-profit publisher of Development, is running a Workshop on ‘Development and evolution of the human neocortex‘, organised by Victor Borrell, Wieland Huttner and Arnold Kriegstein. The Company of Biologists Workshops provide leading experts and early career scientists from a diverse range of scientific backgrounds with a stimulating environment for the cross-fertilisation[…]

PhD position in Queen Mary University of London: Evolution of axis specification in annelid worms

Posted by on February 23rd, 2018

A PhD studentship is available for a project on the evolution of axis specification modes in spiral cleaving animals. The project will focus on the annelid species Owenia fusiformis, which occupies a key phylogenetic position as the sister lineage to all remaining annelids, and it has recently proven very informative for the study of animal[…]

Why more is better in comparative developmental biology…

Posted by on January 26th, 2018

Our recent paper in “Nature” [1] deconstructs molecular arguments that have been used to homologize bilaterian nerve cords. Our work illustrates well the strength of the comparative approach and the broad sampling across the animal tree of life that we use in my research group at the Sars Centre for Marine Molecular Biology.   Evo-Devo[…]
