A research paper published in the journal Nature Materials, the result of the collaboration between a group of theoretical physicists from the International School for Advanced Studies (SISSA) in Trieste and a group of experimental physicists from the University of Basel, reveals the secrets of the nanofriction produced when an atomic force microscope observes the surface of certain materials.
The genome of viruses is usually enclosed inside a shell called capsid. Capsids have unique mechanic properties: they have to be resistant and at the same time capable of dissolving in order to release the genome into the infected cell.
The scientists of the International School for Advanced Studies (SISSA) of Trieste have coordinated a study on the mechanic properties of viruses that have improved their understanding, so much that they were able to make conjectures on the behavior of still little-known viruses
A point may sound like a trivial matter and yet it is a key concept in science and one that has engaged not only mathematicians – who have tried to define it since the early days of this science – but also philosophers, physicists, and theologians. Researchers from different disciplines met at SISSA to discuss this "elusive" topic.
As of November 1, enrolments are open for the fourth edition of the Master's in Complex Actions (MCA) promoted by the Interdisciplinary Laboratory of the International School for Advanced Studies (SISSA) of Trieste, a course that combines the frontiers of science with business practices, to provide an innovative response to global challenges.

Once again this year, Sissa hosted the traditional Welcome Day to welcome new students and publicly present its activities. The event provided an opportunity to make an assessment of the past year's work, to award a number of students and staff members for their achievements and to introduce the latest projects, like this year's Sissa Carpooling.
Paolo Budinich, founder of SISSA and creator of the "Trieste System", which made the city a centre of excellence in the international science scene as well as an important beacon for science education in developing countries, died on November 14, 2013. SISSA, the International School for Advanced Studies pays tribute to this great man, who will also be celebrated on the occasion of the Welcome Day, the annual public event to welcome new students, which will be held on November 20.
The key pathway by which viruses "attack" consists in releasing viral DNA into the infected cell, taking over the host cell's transcription mechanisms and using them to reproduce itself.
In order to fight or exploit to our benefit the action of viruses, scientists are trying to understand this process in detail. A group of researchers – one of whom from SISSA – has studied the timescale of DNA "ejection" (how long it takes and what is the precise sequence of events), and found that it depends on the degree and manner of entanglement of the double strand of DNA inside the virus.
The International School for Advanced Studies of Trieste (SISSA) took part in a study on a sample of professional women volleyball players to better understand the relationship between the cognitive and motor systems.
According to the research, the brain's involvement in motor actions is more complex than was thought so far.
Increasingly small robots that carry out their functions even inside the human body. No, this isn't a sci-fi dream but a close possibility. On one condition: the miniaturization of these devices requires them to acquire the same "softness" and flexibility as biological tissues.
