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.

Two properties are particularly sought after in materials for technology (for a variety of devices from sensors to computer memory, etc.): magnetism and ferroelectricity. Obtaining materials with both qualities is highly desirable. At the present time, these properties have shown to be almost entirely mutually exclusive, but a new study conducted by SISSA/Northwestern University introduces an innovative method which may soon become reality.
If we read about someone who is smiling and happy, without realizing it, we smile as well, and a similar reaction also occurs for the other emotions. If, however, the text is not in our mother tongue but in a second language, then our mind and body react in a blander manner. This effect, according to Francesco Foroni, the author of a new study that observed the phenomenon for the first time, may depend on the different way we learn our mother tongue and a second language.
There are languages that place the verb between the subject and the object (SVO order—Subject/ Verb/ Object) while others place it at the end of the trio (SOV order). The order of these elements, far from being purely decorative, influences efficiency of expression.
In old stars there is too little Lithium – 7, a primordial isotope which was created along with the universe in the first 3 minutes, and scientists do not know why. There has even been some question of whether it was a problem of the big bang theory, the theoretical framework that explains much of what we know about our Universe. A team led by SISSA (in collaboration with INAF - Astronomical Observatory of Trieste, and The University of Padua) revisited this “lithium problem”.
Even fragmentary information can be used to understand which mechanical subunits make up a protein and how these move in relation to one another, with a view to establishing how the molecule carries out its functions. To this end, a SISSA research group (in collaboration with Temple University in Philadelphia) has developed a new method for the computerized analysis of the internal dynamics of molecules, demonstrating its efficiency and versatility. The study has been chosen as the cover story of the journal Structure.
Social cognitive neuroscience is a relatively young but promising field that stems from the encounter between cognitive neuroscience and social cognition studies. The journal Cortex is devoting a whole issue to the subject (available online on August 1 and in print on September 1), which has been coordinated by SISSA and the University of Oxford.
