In memoriam: Margarita Metallinou
Margarita was MSc student at IBE (2008-09), and Phd student (2009-13).She was always enthusiastic towards scientific challenges and created a stimulating atmosphere around her. She passed away on 2nd July 2015 in an unfortunated accident while doing research in Zambia. Although she is not anymore among us, her memories will live on.
XV Jornada de Biologia Evolutiva
Dimarts, 23 de juny, la Secció de Biologia Evolutiva de la Societat Catalana de Biologia (SCB), filial de l’Institut d’Estudis Catalans, va reunir a Barcelona una norantena d’investigadors amb motiu de la celebració de la quinzena edició d’una de les jornades científiques amb més tradició i seguiment de la SCB: la de biologia evolutiva.
DNA regions may evolve differently
The adaptive history of coding and noncoding sequences seems to be decoupled. Ref. Art.: Santpere G, Carnero-Montoro E, [7 authors], Navarro A, and Bosch E (2015). Analysis of Five Gene Sets in Chimpanzees Suggests Decoupling between the Action of Selection on Protein-Coding and on Noncoding Elements. Genome Biol Evol
Chasing butterflies in Southern Italy
Last week, Roger Vila and colleagues from IBE (CSIC-UPF), travelled across gorgeous italian landscapes to study and collect butterflies, in order to discover and describe their still largely unknown diversity. The trip was part of the Butterfly Week, a research initiative that involves researchers and citizens.
Populations in eastern Africa have a very rich genetic diversity
They found a common origin for most Nilo-Saharan speaking groups. Ref. Art.: Dobon B, Hassan HY, Laayouni H, [5 autors], Comas D, Netea MG, and Bertranpetit J (2015). The genetics of East African populations: a Nilo-Saharan component in the African genetic landscape. Scientific Reports
Gerard Talavera expedition in Chad featured at National Geographic
"Collecting Butterflies in Chad", a picture of Gerard Talavera collecting butterflies in Chad and taken by Roger Vila, has been featured in the section "Explorer Moment of the Day" of National Geographic.
Cockroaches can help us understand developmental processes
Scientist have studied the EGFR signaling pathway in the ovaries of cockroaches. Ref. Art.: Elshaer N, and Piulachs, MD. (2015) Crosstalk of EGFR signalling with Notch & Hippo pathways to regulate cell specification, migration & proliferation in cockroach panoistic ovaries. Biology of the Cell
Origin and evolution of lysyl oxidases
New study provides a taxon-wide evolutionary analysis of LOX, a key enzyme in for the extracellular matrix. Scientists show that LOXs have a pre-animal ancestry, being present already in archaea and bacteria. Ref. Art.: Grau-Bové, X., Ruiz-Trillo, I., Rodriguez-Pascual, E. (2015). Origin and evolution of lysyl oxidases. Scientific Reports.
Robots that have evolved their own language
Luc Steels conducted the first large-scale experiment that entailed communication between humans and robots. Now, publishes The Talking Heads Experiment: origins of words and meanings, the book that describes in detail the results of the experiment.
When Red Natura it is not enough
Scientists found no differences in the levels of representation between protected species and those which are not. Ref.Art.: Lison F, Sanchez-Fernandez D, and Calvo JF (2015). Are species listed in the Annex II of the Habitats Directive better represented in Natura 2000 network than the remaining species? A test using Spanish bats. Biodiversity and Conservation
