Dr.Massimo Di Giulio (Laboratory for Molecular Evolution, Institute of Genetics and Biophysics “Adriano Buzzati-Traverso”, CNR, Napoli, Italy) will be giving an IAS-Research Talk entitled “On the rigin of the tRNA Molecule” on Tuesday, June 11th 2013, at 11.30 at the Carlos Santamaria Building Room B14.
A model has been proposed suggesting that the tRNA molecule must have originated by direct duplication of an RNA hairpin structure [Di Giulio, M., 1992. On the origin of the transfer RNA molecule. J. Theor. Biol. 159, 199–214]. A non-monophyletic origin of this molecule has also been theorized [Di Giulio, M., 1999. The non-monophyletic origin of tRNA molecule. J. Theor. Biol. 197, 403–414]. In other words, the tRNA genes evolved only after the evolutionary stage of the last universal common ancestor (LUCA) through the assembly of two minigenes codifying for different RNA hairpin structures, which is what the exon theory of genes suggests when it is applied to the model of tRNA origin. Recent observations strongly corroborate this theorization because it has been found that some tRNA genes are completely separate in two minigenes codifying for the 5’ and 3’ halves of this molecule [Randau, L., et al., 2005a. Nanoarchaeum equitans creates functional tRNAs from separate genes for their 5’ and 3’ halves. Nature 433, 537–541]. It is shown that these tRNA genes codifying for the 5’ and 3’ halves of this molecule are the ancestral form from which the tRNA genes continuously codifying for the complete tRNA molecule are thought to have evolved. This, together with the very existence of completely separate tRNA genes codifying for their 5’ and 3’ halves, proves a non-monophyletic origin for tRNA genes — as a monophyletic origin would exclude the existence of these genes which have, on the contrary, been observed.

Workshop “Synthetic Modeling of Life and Cognition: Open Questions” (SMLC 2013)
12-14th September 2013, University of Bergamo, Italy
Luisa Damiano (University of Bergamo)

In recent decades researchers in various scientific domains have been working intensely on procedures directed to exploring life and cognition in a “synthetic” way, i.e. through modeling in artificial systems. Research on biological and cognitive processes is thus been increasingly based on implementations in “software” (simulations), “hardware” (robots) and “wetware” (chemical systems) used as scientific models of the processes in question. This scientific development is often seen as the emergence of a new general methodology, a “synthetic methodology”, slated to become a dominant force in science. This synthetic methodology poses a challenge for both science itself and the philosophy of science: to define the possibilities, the limits, and the ways of the synthetic modeling of life and cognition, and its relevance for biological, behavioral, cognitive, and social sciences.
The workshop “Synthetic Modeling of Life and Cognition: Open Questions” will tackle this challenge by creating a strongly interdisciplinary forum that can formulate and address these fundamental questions. The workshop brings together pioneers of the synthetic exploration of life and cognition from different scientific domains (computer science, synthetic biology, cognitive, developmental, social robotics…), and invites them to discuss with philosophers and other specialists studying this emerging form of scientific investigation.

Call for Papers
The SMLC 2013 workshop adopts an “Open Questions” format. – This means that the SMLC 2013 call for papers contains a list of questions on the synthetic modeling of life and cognition formulated by members of the Program Committee and other selected specialists on the basis of their expertise and in accordance with the topics of the workshop.
The SMLC 2013 workshop questions are cutting-edge open questions defining the agenda of the nascent interdisciplinary community dedicated to support the reflected and cooperative development of the synthetic modeling of life and cognition.
We welcome abstracts presenting and critically supporting original approaches directed to tackle the issues defined by the questions, and able to stimulate discussions and the emergence of new research lines in the interdisciplinary community created by the workshop.
The list of the SMLC 2013 workshop open questions can be found below. The questions are divided in three groups on the basis of their contents, and each question has an ID number.
We invite specialists from all the different research fields involved in this highly interdisciplinary forum to submit abstracts. In particular we welcome researchers from biology, synthetic biology, computational biology, AL, cognitive sciences, sciences of complex systems, computer sciences, AI, cognitive robotics, developmental robotics, social robotics, philosophy of science, philosophy of mind, philosophy of biology, philosophy of cognitive science, epistemology.
The Program Committee will select the papers to be presented at the workshop as talks through a double-blind peer review process.
We are planning to publish proceedings of the conference with a reputed publisher.
Information on how to prepare your abstract(s):
Each abstract should be anonymised for blind review and should include:
– the ID number and the short version of the question you are addressing;
– the title of your contribution;
– a text of up to 1000 words (excl. references) in a PDF;
– a short abstract of up to 150 words.
