Movement and the ability to divide are two fundamental traits of living cells. The origin of these abilities could rely on very simple physical mechanisms, which have been simulated by scientists of the International School for Advanced Studies (SISSA) of Trieste in a study just published in Physical Review Letters.
A map of how genes vary in biological tissues: a huge project that required the collaboration of dozens of laboratories worldwide, including the Neurogenomics Laboratory of the International School for Advanced Studies (SISSA) in Trieste.
This is the result of a study just published in Nature by the FANTOM consortium (and signed by over two hundred authors). It is only the first of a series of more specific papers that will focus on how the single genes work in each type of tissue.
For astrophysicists neutron stars are extremely complex astronomical objects. Research conducted with the collaboration of SISSA and published in the journal Physical Review Letters demonstrates that in certain respects these stars can instead be described very simply and that they show similarities with black holes.
Researchers at SISSA are developing fast and efficient numerical methods to study the behaviour of molecules and materials. The latest work by Angelo Rosa, published in the journal Physical Review Letters, simulated the behaviour of concentrated solutions of "circular" polymers, providing a far more accurate description of the behaviour of these materials than available in the past.
Small changes in a population may lead to dramatic consequences, like the disappearance of the migratory route of a species. A study carried out in collaboration with the SISSA has created a model of the behaviour of a group of individuals on the move (like a school of fish, a herd of sheep or a flock of birds, etc.) which, by changing a few simple parameters, reproduces the collective behaviour patterns observed in the wild.
Stressed males tend to become more self-centred and less able to distinguish their own emotions and intentions from those of other people. For women the exact opposite is true. This is the main finding of a study just published in Psychoneuroendocrinology, carried out with the collaboration of SISSA in Trieste.
Dal 10 al 15 marzo torna la "Settimana del Cervello", l'evento mondiale per raccontare al pubblico la ricerca scientifica sul cervello. Caffè scientifici, conferenze, mostre, giochi: questa è la ricca offerta di appuntamenti dell'edizione triestina della manifestazione, quest'anno coordinata dal Laboratorio Interdisciplinare della SISSA di Trieste.

Il 14 marzo si è tenuta alla SISSA una conferenza aperta agli studenti delle scuole superiori e ai cittadini, con lo scopo di stimolare "apprendimento, confronto e discussione" sul tema della ricerca medica sulle staminali e delle sue applicazioni terapeutiche. La conferenza è stata l'evento regionale previsto nell'ambito della manifestazione nazionale UniStem Day che si è svolta lo stesso giorno in una quarantina di atenei italiani.
