The brain is divided into functional circuits, each specialized for specific tasks: perception, memory, problem solving… how do these circuits work as a team when required? Research suggests that the secret may lie in synchronization of the rhythms of electrical activity. A SISSA study shows that in rats engaged in a task requiring them to make decisions based on memory, sensory and memory regions synchronize at the theta rhythm, the same rhythm that defines the sweeping movement of their whiskers.
Lo Student Day 2016 ripete il successo dell’anno scorso: alla Scuola Internazionale Superiore di Studi Avanzati (SISSA) di Trieste il 23 febbraio si attendono oltre 500 studenti (provenienti dal Friuli Venezia Giulia ma anche dal resto dell’Italia) del biennio finale delle superiori. Lo Student Day è la giornata in cui la SISSA si dedica tutta ai giovani che dovranno decidere il futuro dei loro studi, raccontando la scienza in un clima di “caos autorganizzato”.
The International School for Advanced Studies (SISSA) in Trieste has won a considerable financial grant from the European Research Council (ERC) Consolidator grant to study advanced reduced order modeling, an area of research that develops methods for simplifying and adapting supercomputing to handheld devices (such as smartphones, tablets, etc). The Principal Investigator (PI) of the project is SISSA Professor Gianluigi Rozza. This is the School’s fourteenth ERC.
We are born with a basic grasp of physics, just enough not to be surprised when we interact with objects. Scientists discovered this in the past two decades. What they did not know yet was that, as early as five months of age, this “naïve” physics also extends to liquids and materials that do not behave like solids (for example, sand), as demonstrated by a new study just published in Psychological Science.
Snake locomotion is a source of inspiration for technology: graceful, silent, adaptable and efficient, it can be implemented on devices designed for the most diverse applications, from space exploration to medicine. A study carried out by a SISSA research group, just published in the Proceedings of the Royal Society A - Mathematical, Physical and Engineering Science, adds to this line of research and proposes a detailed mathematical account of one of the characteristic types of movement adopted by this animal.
On February 25 the local selection of FameLab will be back on stage in Trieste! The international competition challenges young scientists with the talent of communication to tell in just 3 minutes the object of his or her study, or a fascinating scientific topic. No slide shows, graphs, videos: only a fistful of words and a talent for communication are required, to spread to the public the charm and the importance of the scientific research, in a a way that is amusing and easy to grasp.
The polarization vector of cosmic background radiation could rotate during the course of its journey towards us, and if it did, it could also cause trouble for the Standard Model for electromagnetic interactions. To understand if this rotation is taking place, we need an “eye” that can see great distances, like POLARBEAR, an instrument located in Chile at the top of the Andes.
We learn many things through imitation: how to walk, play an instument, sports, and even more. What are the processes in the brain responsible for imitation? For some years now, science has been examining the role of mirror neurons, but there is still much to understand. One study focusing on neurological patients showed that at least two components are involved in imitating gestures, each from a different hemisphere of the brain. The study, which SISSA participated in, was published in Neuropsychologia.
What is the mechanism of action of metal-based chemotherapy drugs (the most widely used for treating common cancers like testicular or ovarian cancer)? How can we improve their effect and reduce their toxicity? A new study combining experiments and theory has broadened our knowledge of the molecular mechanisms of these active drugs to help experimentalists devising increasingly effective drugs with fewer side effects. The study, just published in the journal ChemMedChem, was conducted with the participation of International School for Advanced Studies (SISSA) of Trieste.
At times, to understand something well, it is useful to rebuild it from scratch. It happens with prions as well: in collaboration with the BESTA Institute in Milan, the Laboratory of Prion Biology at SISSA in Trieste assembled artificial prions, devising a method for synthesizing them in a series. Lab tests showed that synthetic prions act like their biological counterparts. Results will be published on December 31 in one of the most respected journals in the industry, Plos Pathogens.
