Smooth or grainy?

A paper by Stefano Liberati from SISSA has been selected as one of the 2013 Highlight papers (the best papers of the year) of the journal Classical and Quantum Gravity. The paper is a systematic review of the methods devised by scientists since the 90s to test Einstein's laws of Special Relativity, up to the highest observable energies. These types of tests are important: deviations from Special Relativity could in fact indicate that space-time is not continuous but grainy. 

Emotions in Parkinson’s disease

A study conducted with the collaboration of the International School for Advanced Studies (SISSA) of Trieste investigates the origins of the difficulty recognizing certain emotions that affects patients with Parkinson's disease. Is this impairment caused by the disease itself or is it in part the consequence of a widely used treatment (deep brain stimulation)?

3D printing and “mechatronics” at SISSA

The arrival of a new 3D printer marks the start of a "mechatronic" age at SISSA. The new laboratory will enable SISSA investigators to be increasingly self-sufficient in designing and constructing the experimental setups and machinery needed for their studies.

Thanks to sophisticated equipment, including a new-generation 3D printer, and to the laboratory's expertise, scientists will no longer have to adapt their research to the constraints of existing technology but will be able to work more creatively, developing technology that fits the needs of scientific investigation.

Nanofriction on the tip of the microscope

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.

A look at the infinitely small

Via Bonomea, 265 - Trieste

Until a short time ago scientists thought it was impossible to observe objects smaller than 200 nanometres under an optical microscope. Stefan Hell, a physicist of the Max Plank Institute, found a way to overcome this limit, inventing a method to observe biological tissues down to the molecular scale. The physicist talked about his research at a public conference at SISSA. 

Viral puzzles

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

Tidy knots are faster

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.

Shortlisted for the Barilla award

Helping people waste less food: this is the aim of the project of three former students of the SISSA Master's in Complex Actions, among the ten finalists for the YES 2013 award offered by the Barilla Center for Food and Nutrition.

The project, started while attending the Master's course in 2012, proposes a new way of recording and reducing the amount of food that families waste, and is especially aimed at young people (with the collaboration of schools).

Farewell to the father of Trieste City of Science

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.

SISSA Welcome Day: focussing on students

November 20th 2013 

From 9.30 AM onwards

SISSA, Main Lecture Hall

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. 

Studying micromotility with over a million euro

Microrobots of the future, whether surgeons, cleaners or transporters, will have to be able to move about in an efficient and precise manner. To make this possible and improve the locomotor skills of these artificial devices, scientists like Antonio De Simone and his group at the International School of Advanced Studies (SISSA) in Trieste are studying the movement of unicellular organisms. De Simone has just been awarded a Advanced Grant of the European Research Council (ERC) amounting to 1,300,000 euro.

The chromosome geographer

SISSA, Main Lecture Hall

Among the most interesting discoveries in recent decades, the one that cellular DNA does not appear as a shapeless tangle, but rather is arranged into discrete "geographic" territories may be considered truly revolutionary. The first to suggest these chromosome "maps" was Thomas Cremer, a scientist whose studies represent a milestone in the fields of biology and genetics. Cremer gave a public lecture at SISSA, on Wednesday October 23.
