The Drosophila fly brings to light the role of morphogens in limb growth

Posted by on July 5th, 2017

• Scientists at IRB Barcelona clarify the function of the genes that drive wing development in the fruit fly Drosophila melanogaster. • Published in the journal eLife, this study unveils that the Dpp morphogen is necessary for wing growth but that its gradient does not govern this process. • Understanding the development of limbs in[…]

In time of revision: of Wingless and morphogens

Posted by on December 27th, 2013

In time of revision: of Wingless and morphogens Alfonso Martinez Arias The recent publication of the important work of C. Alexandre, LA. Baena and JP. Vincent on the molecular requirements for Wingless signalling in Drosophila (http://www.nature.com/nature/journal/vaop/ncurrent/full/nature12879.html) offers an opportunity to consider the relationship between ideas and facts in modern developmental biology. The work reports the[…]

A Discussion between Eric Wieschaus and Marcos González-Gaitán

Posted by on September 22nd, 2011

Eric Wieschaus is a Professor at Princeton University, USA. He was awarded the Nobel Prize in Physiology or Medicine in 1995, together with Christiane Nüsslein-Volhard and the late Edward B. Lewis, for their work “uncovering the genetic control of embryonic development”. Throughout his career, he has been interested in the mechanisms underlying patterning and morphogenesis[…]

Final Day at The EMBO Meeting – Behaviour and lots of Movies!

Posted by on September 14th, 2011

The famous Richard Axel kicked off the last day in Vienna by presenting new data on how olfactory information is projected from the olfactory bulb to the cortex. After his keynote lecture, the talks in the plenary session continued with a focus on the brain and how it drives behaviour in different circumstances or environments[…]
