Prof. Eric Huysecom was elected President of the Society of Africanist Archaeologists (SAFA) during the 23rd Business meeting which is kept at The University of Toulouse on the 1st of July 2016.

This year, we will hear from specialists, including a Nobel Prize, in areas that are profoundly transformed by the advent of genomics.

Jozsef Zakany collaborated to a study led by researchers from the NIH, who uncovered the existence of an interdigit signaling center that instructs coordinate phalanx-joint formation in mice embryos.

The Nobel Prize in Physiology or Medicine 2016 was awarded to Yoshinori Ohsumi "for his discoveries of mechanisms for autophagy”. Brigitte Galliot explains the importance of this discovery.

For the past fifteen years, an interest for Quantitative & Systems Biology has been raising in the scientific community. Major advances in this direction have been driven by the integration of physics and computer science approaches with innovative technological developments in molecular biology, optics, micro- and nano-manipulations. Although Quantitative & Systems Biology is very recent, it has already significantly spread through many fields of life sciences: genetics, biochemistry, cell biology, development, ecology and many others.

The winner of this first edition of the 3R Award is Professor Emi Nagoshi, from the Department of Genetics and Evolution of the Faculty of Sciences, for her project entitled “A conserved role for p48 homologs in protecting dopaminergic neu­rons from oxidative stress”. She will receive her Award on Monday, September 19th at 9:45am.

To forge better links not only between university research laboratories but also with companies, there should be more room for bottom-up, collaborative research in the EU’s framework research programme – specifically in Horizon 2020’s pillars II and III. Today, the League of European Research Universities (LERU) issues a Note to call attention to this issue. Feel free to read the attached PDF.

The fifth edition of the Louis-Jeantet Symposium will be organised by Denis Duboule, chairman of the Department of genetics and evolution at the Faculty of Science, University of Geneva, and professor at the EPFL School of life sciences, and by Konrad Basler, chairman of the Institute of Molecular Life Sciences, University of Zurich.

Champion of regeneration, the freshwater polyp Hydra is capable of reforming a complete individual from any fragment of its body. It is even able to remain alive when all its neurons have disappeared. Researcher the University of Geneva have discovered how: cells of the epithelial type modify their genetic program by overexpressing a series of genes, among which some are involved in diverse nervous functions. Studying Hydra cellular plasticity may thus in uence research in the context of neurodegenerative diseases. The results are published in Philosophical Transactions, the journal of the Royal Society.

Researchers in the laboratory of Michel Milinkovitch have identified in the corn snake the mutation responsible for amelanism, a form of albinism due to a defect in the production of melanin (the black and brown pigments of the skin). The skin of the wild type corn snake exhibits a light orange background colour covered with a pattern of dark orange dorsal saddles and lateral blotches that are outlined with black. However, some individuals do not correspond to that standard morphology: they lack all signs of melanin in the skin and eyes. The Swiss team decided to search for the DNA mutation that determines that specific coloration. To this end, they bred wild-type corn snakes with amelanistic individuals and they sequenced each offspring born from that cross. “Thanks to that large amount of sequencing data, we identified the malfunctioning gene”, explains Milinkovitch. That gene is called OCA2 and codes for a receptor located in the membranes of intracellular compartments, called melanosomes, that contain melanin. This receptor controls the proper level of acidity allowing for the synthesis of melanin.
