Jesús Lozano, who did his PhD at the Institute of Evolutionary Biology of Barcelona (CSIC-UPF), won this prize for his thesis "Mechanism of action of the juvenile hormone during insect metamorphosis", defended in 2014 at the Faculty of Biology of the UB and supervised by Xavier Bellés, CSIC professor and IBE director from 2008 until 2016. Lozano is currently a Marie Skłodowska-Curie Fellow at the University of Bristol.
Astronomers are borrowing principles applied in biology and archaeology to build a family tree of the stars in the galaxy. By studying chemical signatures found in the stars, they are piecing together these evolutionary trees looking at how the stars formed and how they are connected to each other. The signatures act as a proxy for DNA sequences. It’s akin to chemical tagging of stars and forms the basis of a discipline astronomers refer to as Galactic archaeology.
The Board of Trustees of the IBE, a joint centre of Pompeu Fabra University and the CSIC, has appointed the scientist Tomàs Marquès-Bonet as the new director of the Institute, replacing his predecessor Xavier Bellés, who has been in charge of the institution for the last eight years.
Pompeu Fabra University and the Institute of Evolutionary Biology are launching the project NEWS: Prediction of Technological Innovation in Culturomic Networks, aimed at understanding the origins of innovation through the development of a theory of technological evolution.
IBE Scientists have discovered that a gecko subspecies could actually contain up to 14 different species. These species are called cryptic because it is necessary to analyse them genetically to be able to distinguish one from the others. These results are very important since, once differentiated, it has been seen that some of them may be in endangered.
The rate of genomic adaptation is determined by the rate of environmental change, the availability of beneficial mutations, and the efficiency of positive selection. Scientists conclude that the impact of selection on the genomic diversity of a species increases with the effective population size, most likely due to the differential influx rate of beneficial mutations.
Natural selection favours fragile and unhealthy old age if it is due to mutations that are beneficial during childhood. As of 40-50 years of age, natural selection is blind because we have already passed on our genes, whether beneficial or not, to our descendants. Knowing the genes and mutations involved in ageing may help to develop new strategies for the treatment of age-related diseases.
On 7 and 8 March, on the occasion of a B-Debate, an initiative promoted by Biocat and Obra Social “la Caixa”, national and international experts in Artificial Intelligence will come together at the CosmoCaixa to talk about the dreams, the riscks and the reality of AI. This B-Debate organized by Luc Steels, principal investigator at the Isntitute of Evolutionary Biology.
Scientists at the Institute of Evolutionary Biology find common features in genes associated with diseases. The study, published in the journal Human Molecular Genetics, suggests a degree of biological importance in the genome depending on the linkage of genes to disease.
IBE participates practical course “Uncovering the hidden diversity of the oceans” run by the Multicellgenome Lab. In this course students will be the first one to study a new species of Sphaeroforma that was isolated from the gut of a crustacean from the Arctic Ocean.
