It is a bit like business partners: if one of the two parties changes strategy – voluntarily or otherwise – to keep the business going, the other has to adapt in turn. The leap from business ventures to the structure of proteins might seem a little bold. Yet, this concept of “balanced changes” is precisely the guiding principle of an important new study that just appeared in PNAS, the journal of the National Academy of Sciences of the United States.
“Our goal? To radically innovate numerical simulations in the field of thermal transport to take on the great science and technology issues in which this phenomenon is so central. This new study, which has designed a new method with which to analyse heat transfer data more efficiently and accurately, is an important step in this direction”. This is how Stefano Baroni describes this new research performed at Trieste’s SISSA by a group led by him, which has just been published in the Scientific Reports journal.
A laser pulse, a special material, an extraordinary property which appears inexplicably. These are the main elements that emerge from a research conducted by an international team, coordinated by Michele Fabrizio and comprising Andrea Nava and Erio Tosatti from SISSA, Claudio Giannetti from the Università Cattolica di Brescia and Antoine Georges of from the Collège de France. The results of their study have recently been published in the journal Nature Physics.
Do you express your emotions? Are you able to name them, talk about them, relate to your feelings? If your answer is not an unqualified yes, you might be among the 10 percent of the healthy population who has difficulty processing the emotions they experience: a psychological condition known as alexithymia. An alexithymic individual has difficulty, to a greater or lesser degree, in relating to the sensations – ranging from joy to fear, from disgust to anger – which make up our experience.
A novel research path for a rare variant of Rett Syndrome might turn into therapy for several other neurological pathologies. This is what is hoped for by the project of the Cerebral Cortex Development Lab of Trieste’s SISSA, recent winner of a funding provided by the Jerome Lejeune Foundation, a French institution engaged, among other things, in supporting research on Rett Syndrome.
Parkinson’s disease and prion diseases are very different from each other as regards both origins and course.
Like in a nail-biting thriller full of escapes and subterfuge, photons from far-off light sources, such as blazars, could go up against a continuous exchange of identity in their journey through the Universe.
To move a nanoparticle on the surface of a graphene sheet, you won’t need a “nano-arm”: by applying a temperature difference at the ends of the membrane, the nanocluster laying on it will drift from the hot region to the cold one. In addition, contrary to the laws ruling the world at the macroscale, the force acting on the particle – the so-called thermophoretic force – should not decrease as the sheet length rises, sporting a so-called ballistic behavior.
The dichotomy concerns the so-called angular momentum (per unit mass), that in physics is a measure of size and rotation velocity. Spiral galaxies are found to be strongly rotating, with an angular momentum higher by a factor of about 5 than ellipticals. What is the origin of such a difference? An international research team investigated the issue in a study just published in The Astrophysical Journal. The team was led by SISSA Ph.D.
Another step forward towards superconductivity at room temperature: an experiment at the cutting edge of condensed matter physics and materials science has revealed that the dream of more efficient energy usage can turn into reality. An international collaboration, led by the scientists of Italy’s International School for Advanced Studies (SISSA) in Trieste, Università Cattolica di Brescia and Politecnico di Milano used suitably tailored laser pulses to snap the electronic interactions in a compound containing copper, oxygen and bismuth.
