A closer look to Riodinidae butterflies
The family is ~96 My old and has ~1500 species (8% of all butterflies). It exhibits the greatest variation in wing shape, color and pattern in any butterfly family. Espeland M, et al (2015).

Tomàs Marquès Bonet participates in a NIH-funded study about autism
The National Institutes of Health will fund a project focused on the genetic mutations in the neurons of patients with autism. The other partners of the consortium are Nenad Sestan (Yale School of Medicine), and Christopher Walsh and Peter Park (Harvard Medical School). Text in Catalan.
Gene deletions and duplications reveal our genetic storyline
By looking closely at DNA variation across a vast number of human populations, researchers now have a better idea of the genetic mechanism behind ethnic diversity. Ref.

Jaume Bertranpetit receives the Narcís Monturiol Medal
First given by the Catalan Government in 1982, these awards recognize the contribution of Catalan organisations and authorities to the fields of science and technology. This year there are a total of 16 awardees.
Les noves tècniques de seqüenciació d'ADN milloren l'estudi genètic de restes òssies de la guerra civil espanyola
F. Casals, cap del Servei de Genòmica de la UPF; J. Bertranpetit i F. Calafell, investigadors de l'IBE, i A. Malgosa, investigadora de la UAB, han presentat un estudi pioner de genètica forense de les restes d'una fossa comuna de la guerra civil.
Images from the Mind
Researchers at the IBE collaborated in the development of a Brain-Computer Interface that reconstructs images with the mind, using electro- encephalography signals.

Natural mutation found in flies confers them with a faster developmental time
This insertion was first hypothesized to be adaptive to temperate environments. Ref. art.: Ullastres A, Petit N, González J (2015). Exploring the Phenotypic Space and the Evolutionary History of a Natural Mutation in Drosophila melanogaster. Molecular Biology and Evolution
DNA suggests that the diversity of European butterflies could be seriously underestimated
Scientists have obtained the DNA sequences of the 228 known butterfly species in the Iberian peninsula and compared it to available data for Europe. Ref. Art.: Dinca, V., et al (2015) DNA barcode reference library for Iberian butterflies enables a continental -scale preview of potential cryptic diversity. Sci Rep
Discovery of new genes that may explain why insects are the most evolutionarily successful group of organisms
Eglps may have favored the appearance of the pupal stage in the life cycle of insects. Finn RN, Chauvigné F, Stavang JA, Belles X & Cerdà J. 2015. Insect glycerol transporters evolved by functional co-option and gene replacement. Nat Comms
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).
