Being all in one piece is not always a good strategy for resisting external strain. Biological tissues are well aware of it: they tend to crack simultaneously and gradually in several places, rather than catastrophically in one place only. This makes them particularly resistant. A group of SISSA researchers conducted a theoretical study that explains the mechanism underlying this phenomenon, which was experimentally observed in epithelial cell cultures. By doing so, they take their first steps towards creating artificial materials with features inspired by biomaterials.
A method for data analysis used in medical diagnostics has been tested for the first time on resting state functional magnetic resonance imaging (fMRI) data. The method, which relies on “fuzziness”, proved to be as robust as the well-known and regularly used sample entropy (SampEn) method but with the advantage of offering greater detail than sample entropy The findings have been published in Medical Engineering and Physics.
They turn into bad prions, but no one knew how. Now a group of SISSA scientists has finally identified the mechanism underlying the pathological transformation of prion proteins: it all depends on a metal, copper, and its bond with the protein. The findings have just been published in Scientific Reports.
A face with an emotionally charged expression, especially if the emotion is anger, can influence the course of our actions, according to a study by the International School for Advanced Studies (SISSA) of Trieste published in Cognitive Neuroscience. The distracting effect is potentially dangerous in come situations (for example, when driving).
Si sono appena aperte le iscrizioni alla seconda edizione del concorso fotografico “De Rerum Natura, la scienza in uno scatto – Luce e visione”, organizzato dal Laboratorio Interdisciplinare della Scuola Internazionale Superiore di Studi Avanzati (SISSA) di Trieste. Il concorso è dedicato alla natura e alla scienza. La partecipazione è aperta a tutti. I vincitori riceveranno dei premi (520, 320 e 200 euro rispettivamente al I, II e III classificato in ciascuna categoria) e avranno la possibilità di esporre le proprie fotografie alla SISSA.
SISSA has received a 3-year grant of roughly 200 thousand euros for a team of researchers to study gravitational waves in cosmic microwave background radiation (CMB). The work is part of a broader project, RadioForegrounds, within the Horizon 2020 framework of the European Commission with other European institutions (Institute of Astrophysics-- Canary Islands, The University of Cantabria, Cambridge University, the University of Manchester and CNRS in France as well as the private company, Trilogic). SISSA will focus on ridding cosmic signals of contaminants.
Classes of the 2015/16 edition of the Master in High Performance Computing (MHPC) of SISSA/ICTP are starting today, and important news and events have been announced: in February 2016 a workshop featuring renowned guests will be held, and the Erasmus Plus partnership with the University of Ulm in Germany is confirmed, which will allow student exchanges between Italy and Germany.
NS3 is an enzyme specific to the hepatitis C virus. If developed, a drug capable of recognizing and selectively attacking it could fight the disease without side effects for the body. However, to be able to develop one we need to know more about the behaviour of this important protein in the virus replication process. Until now, we have only had some “still images” – obtained with crystallography techniques – of the interaction between the protein and the RNA, which makes the viral genome.
Ancora pochi giorni (fino al 29 settembre) per iscriversi alle selezioni per il nuovo biennio dello storico Master in Comunicazione della Scienza “Franco Prattico” della SISSA di Trieste. Stanno per scadere anche i termini per l’iscrizione (12 ottobre) alla “Scuola in comunicazione del rischio per la salute e per l’ambiente” della SISSA. È il momento di affrettarsi.
