Postdoc – Epigenomics of spiral cleavage

Posted by on December 19th, 2018

An ERC-funded Postdoctoral Research Assistant position is available at Queen Mary University of London (QMUL) in Dr José M (Chema) Martín-Durán’s group, to work on the epigenetic regulation of conditional and autonomous development in spiral cleaving animals (e.g. annelid worms, molluscs, and nemerteans).   Queen Mary is one of the top research-led universities in the[…]

PhD – Comparative annelid genomics

Posted by on December 19th, 2018

Mutualistic relationships between bacteria and complex organisms have repeatedly evolved and this has allowed host organisms to exploit new environments and foods. Siboglinid annelid worms (e.g. Riftia and Osedax) are able to live in particularly extreme environments including deep sea hydrothermal vents and carcases thanks to a particular symbiosis: as juveniles, these annelids acquire bacteria from the[…]

Sex combs in motion

Posted by on November 14th, 2018

Using computer simulations and mathematical modeling to study the evolution of morphogenesis   Juan N. Malagon and Ernest Ho tell the story behind their recent paper in PLOS Computational Biology. In the Larsen lab, we are interested in testing a 50-year old question: How do sex combs rotate in fruit flies? Despite extensive studies of the[…]

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[…]

Testing Zimmermann’s Telome Theory

Posted by on August 1st, 2018

A perspective on our recent paper ‘CLAVATA was a genetic novelty for the morphological innovation of 3D growth in land plants’1.   In the 1950’s, the German botanist Walter Zimmermann (photo here) hypothesized a series of developmental transitions enabling plant forms to radiate during evolution2. Zimmermann’s so-called Telome Theory has received much attention from those[…]

Evo-chromo: towards an integrative approach of chromatin dynamics across eukaryotes

Posted by on July 18th, 2018

***Deadline to apply for funded ECR places is July 20!***   In November, the Company of Biologists is hosting the latest in its series of Workshops. ‘Evo-chromo’ aims to integrate skills and interests of the fields of chromatin biology and evolutionary biology – if you are an early career researcher and this all sounds appealing[…]

The people behind the papers – Sa Geng & James Umen

Posted by on April 19th, 2018

The transition to multicellularity in eukaryotes appears to be intimately linked to the transition from isogamy (gametes of the same size) to anisogamy (gametes of distinct sizes), and indeed to oogamy, a form of anisogamy with a large, immotile egg and a motile sperm. Volvocine algae provide a useful and fascinating model to study how[…]

PhD position: Single-cell elucidation of the evolution of an embryonic transcriptional programme

Posted by on April 3rd, 2018

The project: Single-cell approaches are revolutionizing developmental biology. We can now  trace in time the behavior of each cell in a live developing organism (1). In parallel, single-cell transcriptomics and genomics gives access to the transcriptional state of each cell (2). Combination of these two approaches promises to unravel how genomic information translates into individual[…]

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[…]

How to build and evolve a nervous system

Posted by on November 20th, 2016

Author Summary of “A gene regulatory network for apical organ neurogenesis and its spatial control in sea star embryos”.   Alys M. Cheatle Jarvela, Kristen A. Yankura, Veronica F. Hinman Development 2016 143: 4214-4223; doi: 10.1242/dev.134999 Very similar cell types are found across the animal tree of life. Much of animal diversity, therefore, arises not from the formation of new cells, but[…]
