UniTS remembers David Clyde Snelling, an extraordinary teacher and humanist, a lover of history and languages, art and music, who has recently passed away.

Having moved to Trieste from England in the early 1970s, he soon joined the then School for Interpreters (SSLMIT) as a lecturer in simultaneous interpretation.

He would remain there for more than 40 years, leaving an indelible mark on the School, of which he also served as Director, and on generations of interpretation students, many of whom went on to become conference interpreters and, thanks in part to his teaching, reached the highest levels of the profession.

His versatility, intellectual vitality, analytical precision, teaching rigour, generosity in his relationships with colleagues and students, and his extensive international network made a fundamental contribution to the life of the institution, helping to consolidate and enhance its prestige worldwide.

Four women and one man, five books exploring science from invisible microorganisms to the sense of touch. Antonella Fioravanti takes readers into the unseen world of microorganisms that sustain the planet's delicate balance (Journey into the Invisible World). Vincenzo Levizzani shows how fog, wind and storms have shaped the course of human history (The History of the World in Ten Storms). Daniela Minerva gives voice to women's knowledge that remained on the margins of mainstream medicine for centuries (Plural Women's Medicine), while Beatrice Mautino explores the uncertainty and vulnerability of those who turn to science at one of life's most fragile moments—illness—in Vertigo. Completing the shortlist is Marta Paterlini's The Thinking Skin, which brings touch—the oldest and perhaps most overlooked of our senses—back to the heart of what makes us human.

These are the five finalists for the fourth edition of the Trieste Next – Science Book of the Year Award, promoted by ItalyPost and the Municipality of Trieste – Department of Education, Schools, Universities, Research, Employment and Innovation, under the scientific leadership of the University of Trieste. Presented as part of the Trieste Next festival, the award celebrates the most significant recent publications that explore and interpret the world of science.

The shortlist was selected by the Award's Scientific Jury, which chose five titles from more than 60 books submitted by publishing houses. The shortlisted authors will take part in the fifteenth edition of Trieste Next, entitled "The Shape of Thought. Interactions between Brains and Intelligences," taking place in Trieste from 25 to 27 September. Throughout the festival, each finalist will present their book in a dedicated event introduced by a member of the Scientific Jury. The winner will be chosen by the Readers' Jury, made up of more than 200 science enthusiasts from across Italy, and will be announced during the award ceremony on Sunday, 27 September at 11:30 a.m. on the Trieste Next main stage.

The Scientific Jury is chaired by Donata Vianelli, Rector of the University of Trieste, and includes: Gabriele Beccaria (Tuttoscienze, La Stampa), Fabrizio Brancoli (Deputy Editor-in-Chief, Gruppo Nem Nord Est Multimedia), Maurizio De Blasio (Councillor for Education, Schools, Universities, Research, Employment and Innovation, Municipality of Trieste), Leonardo De Cosmo (ANSA and Le Scienze), Paola Del Negro (Director General, National Institute of Oceanography and Applied Geophysics – OGS), Fabio Pagan, Marco Panara (la Repubblica Affari & Finanza), Nicla Panciera, Paola Pica (Corriere della Sera Innovazione), Caterina Petrillo (President, Area Science Park), Nico Pitrelli (SISSA, Trieste), Davide Re (Avvenire), Fabio Sottocornola (Corriere della Sera), and Camilla Valletti (Managing Editor, L'Indice della Settimana).

Silvia Marchesan, Full Professor of Organic Chemistry at the Department of Chemical and Pharmaceutical Sciences (DSCF) of the University of Trieste, has been elected a Member of the Chemistry Division of the European Academy of Sciences (EurASc).

This prestigious recognition acknowledges Professor Marchesan's pioneering contributions to the field of nanomaterials science, particularly her research on the role of chirality in peptide self-assembly, which has provided fundamental insights for the design and development of functional peptide-based nanomaterials. Her election also recognizes her commitment to promoting interdisciplinary research, science communication, and dialogue across disciplines, cultures, and genders.

"I am deeply honoured to join the Chemistry Division of EurASc," said Silvia Marchesan. "This recognition marks an important milestone for my research group and for our commitment to building collaborations that transcend the boundaries between disciplines and scientific communities. I am delighted to contribute to the Academy's mission of promoting scientific excellence and international cooperation."

The European Academy of Sciences (EurASc) is an independent international organization that brings together some of Europe's most distinguished scientists and engineers to promote excellence in fundamental and interdisciplinary research, strengthen international scientific cooperation, and advance science and technology for the benefit of society. EurASc works alongside and complements the activities of national academies and the European Academies' Science Advisory Council (EASAC).

The European Space Agency (ESA) has presented the largest and most detailed image ever produced of the centre of the Milky Way, the so-called Galactic Bulge: an extremely bright region densely populated with stars. This extraordinary “photograph” opens up new possibilities for scientists, who will be able to confirm the possible existence of exoplanets in this region and measure their mass through the tiny variations in starlight over time.

The Euclid Space Telescope acquired this enormous image in around 26 hours. It is a mosaic made up of nine pointings of its visible-light camera, each covering a portion of the sky larger than the full Moon.

In this image, Euclid captured more than 60 million stars, together with nebulae and star clusters. This extremely populated region of our galaxy is an ideal environment for the search for exoplanets through microlensing.

The news from Euclid is extraordinary: mapping the Galactic Bulge with such precision opens up unique prospects,” commented Gabriele Cescutti, UniTS Professor of Stellar Astrophysics. “Although this specific observing campaign was designed to exploit microlensing and search for exoplanets, such a density of stellar data is also extremely valuable for our research lines at UniTS. In our Department of Physics, we have been working for years on chemical evolution and ‘galactic archaeology’. We use spectroscopic and chemical data from stars to reconstruct, through theoretical models, the early history, formation timescales and origin of the elements in the bulge and nucleus of the Milky Way. High-resolution mosaics, such as the one produced by Euclid, are fundamental to understanding the precise distribution and nature of these stellar populations.

The University of Trieste is responsible for the operations of the two scientific instruments at the heart of the Euclid mission: VIS (Visible Instrument) and NISP (Near Infrared Spectrometer Photometer). In detail, UniTS researchers hold responsibility and coordination roles in several Key Projects dedicated to the scientific exploitation of Data Release 1 (DR1), expected around mid-2027, which concerns the study of cosmology through the statistical properties of the distribution and evolution of galaxies. UniTS also contributes to the production of cosmological numerical simulations based on High Performance Computing methodologies.

Ten million cells analysed in less than two hours, with memory usage approximately three times lower than the best existing tools and speeds up to forty times faster on the largest datasets compared with the best existing tools. This is the remarkable result achieved by a group of researchers from the University of Trieste, Area Science Park, SISSA and Human Technopole, who developed DEVIL (Differential Expression with Variational Inference Learning), a new high-performance computational tool. The work has been published in Nature Communications.

Understanding which genes are active in cells is one of the keys to understanding diseases and developing new therapies. Today, the most advanced technologies make it possible to measure gene activity in millions of cells from dozens or hundreds of patients, generating an unprecedented amount of data for biomedical research. This revolution, however, brings with it two major challenges: on the one hand, the risk of errors in data interpretation; on the other, the difficulty of analysing such large volumes of information.

The first challenge is computational: analysing millions of cells requires enormous computing power. Traditional methods are too slow and consume too much memory to handle these volumes: a bottleneck that risks undermining the advantages offered by new data collection technologies. The second challenge is statistical. Cells collected from the same patient resemble one another more than they resemble cells from different patients, because they share the same individual biology, the same environment and the same personal characteristics. Ignoring this fact — as many currently used tools do — can lead to distorted statistical conclusions, with the risk of identifying as “significant” cellular changes that are not actually significant, or, conversely, of missing real ones.

To address these two issues, the researchers, thanks to DEVIL, succeeded in combining statistical rigour and computational speed in an innovative way. From a computational perspective, DEVIL, which was also developed with the support of Fondazione AIRC, was designed to make efficient use of the most advanced parallel computing architectures typical of artificial intelligence. Moreover, DEVIL is not only faster, but also uses less memory — a far from secondary detail. This means that analyses previously reserved for major computing centres can now become accessible to smaller research infrastructures and laboratories. From a statistical perspective, DEVIL addresses the problem through a Bayesian approach that correctly accounts for the structure of the data, treating cells from the same patient as correlated and therefore separating differences between patients from genuine differences in cellular activity.

“This work would not have been possible without ORFEO, the Area Science Park data centre, recently upgraded thanks to funding from Italy’s National Recovery and Resilience Plan,” says Stefano Cozzini, Director of Area Science Park’s Research and Technological Innovation Institute. “The availability of latest-generation GPUs, characterised by extremely high computing performance, together with careful optimisation of the algorithms for this architecture, developed by our team, now makes it possible to use DEVIL to address and solve problems on a significantly larger scale. We are very satisfied: it is not often that one can rely on a team with such high-level expertise, capable of making the most of the resources acquired.”

“Differential expression, that is, the statistical analysis that identifies which genes are significantly more or less active across two or more different biological conditions,” explains Giulio Caravagna of the University of Trieste, “is a mature technology. However, the transition to single-cell analysis has introduced statistical and computational issues that make the integrated analysis of large patient cohorts complex. Our work was developed precisely to overcome this bottleneck, combining methodological innovation and high-performance computing in order to scale up to the analysis of millions of cells from hundreds of patients.”

“In the development of DEVIL, the synergy between classical and Bayesian statistical tools represents a key strength within the reference oncological literature,” says Leonardo Egidi of the University of Trieste, “and makes DEVIL an efficient computational protocol with a strong methodological characterisation. Future developments could involve spatio-temporal models for multiple patients and introduce further computational approximations based on theoretical properties that are currently under study: a valuable combination of statistical, computational and biological expertise.”

DEVIL was tested on two concrete biological case studies. In the first, focused on the identification of immune system cells, the tool proved more precise and specific in recognising relevant biological functions. In the second, concerning the ageing of human muscle tissue, it identified age-related transcriptional changes in a more stable and biologically grounded way, reducing noise and highlighting key processes for subsequent analyses.

DEVIL has been released as free and open-source software, available to laboratories and hospitals around the world, paving the way for a new generation of large-scale genomic analyses for the study of tumours, degenerative diseases and the development of personalised medicine.

Andrea Pappalardo, a student in the Master’s Degree Programme in Diplomacy and International Cooperation at the University of Trieste, has been appointed Italy’s Youth Delegate to the United Nations for the 2026/2027 mandate.

The appointment was announced by SIOI – the Italian Society for International Organization, which has implemented the United Nations Youth Delegate Programme – UNYD in Italy since 2017, in agreement with the Italian Ministry of Foreign Affairs and International Cooperation. The 2026/27 edition of the Programme is held under the patronage of the Italian Youth Agency and with the support of Reale Foundation.

Born in 2003, Pappalardo is originally from south-eastern Sicily and lives in Gorizia, where he obtained his Bachelor’s Degree in International and Diplomatic Sciences and where he is continuing his Master’s studies in the fields of diplomacy, cooperation and international relations.

His appointment follows a national selection process that assessed over 300 applications. Together with Sofia Gioria, a student at Roma Tre University, Pappalardo will represent the views, ideas and priorities of younger Italian generations at the 81st United Nations General Assembly and in the main national and international institutional contexts.

“I take on this role with a great sense of responsibility and gratitude,” said Andrea Pappalardo. “My aim will be to help give voice to young Italians, promoting the values of dialogue, cooperation and participation. I strongly believe in a culture of peace, capable of countering hatred and intolerance, and in the role that younger generations can play in shaping the present and the future.”

Pappalardo’s path combines academic education, civic engagement and student participation. He has been a volunteer with the Italian Red Cross for over six years, an experience that has strengthened his commitment to service, solidarity and the building of relationships based on trust. For the past three years, he has also been part of MSOI Gorizia, the local section of the Student Movement for International Organization, where he served as Deputy Secretary and was later elected Secretary for two consecutive terms.

The mandate of the Youth Delegates to the United Nations will begin in September with the handover from the 2025/2026 Delegates and will include, in addition to the mission to New York, the organisation of events and meetings at universities, schools, institutions, bodies and associations.

Rector Donata Vianelli described the appointment as “a source of great satisfaction and pride for me and for the entire academic community of the University of Trieste. This achievement not only rewards the talent and dedication of students such as Mr Pappalardo, but also confirms the excellence of the educational path offered by our University in the field of international relations.”

The University of Trieste, the Department of Medical Sciences, and the School of Specialization in Forensic Medicine express their deep sorrow at the passing of Dr. Fulvio Costantinides, former Researcher in Forensic Medicine.

A graduate in Medicine and Surgery from the University of Trieste, Dr. Costantinides was among the first members of the Trieste School to obtain a Specialization Diploma in Forensic Medicine (1981). From the very beginning of his career, he dedicated himself to crime scene investigations and post-mortem examinations, including external inspections and autopsies. He carried out these activities on behalf of the Judicial Authorities with great commitment and enthusiasm throughout his professional life.

A knowledgeable and empathetic educator, he was a forensic pathologist distinguished by a rigorous methodological approach and exceptional analytical, synthetic, and intuitive abilities. His colleagues remember him as a highly skilled and meticulous forensic physician when dealing with expert assessments and medico-legal cases. In this field, discussion and debate were always welcomed, conducted openly and honestly, while maintaining the strictest adherence to procedural rules.

Always present, approachable, and willing to contribute, he taught Forensic Pathology to at least two generations of forensic medicine specialists, leaving a lasting impact on his students and colleagues alike.

An international study has revealed a new piece of Mars’ geological puzzle. The research, led by Brock University (St. Catharines, ON, Canada), in collaboration with the Royal Ontario Museum (Toronto, ON, Canada) and with the contribution of the University of Trieste, has identified for the first time the presence of garnet in a Martian meteorite, opening up new perspectives on the complexity of the processes that shaped the Red Planet.

The study, published in the international peer-reviewed journal Geochemical Perspectives Letters of the European Association of Geochemistry, involved Ana Černok, a researcher at the University of Trieste.

Garnet is a very common mineral on Earth, often associated with metamorphic rocks and with processes occurring under conditions of high temperature, high pressure or in the presence of hot fluids. Until now, however, it had never been recognised in samples from Mars or directly on the Martian surface. Its identification therefore expands the known mineralogical diversity of the planet and suggests the possibility that Mars may have undergone more complex geological processes than previously documented.

The sample analysed is a fragment of the Martian meteorite NWA 8171, preserved in the collections of the Royal Ontario Museum. During the mineralogical and chemical analyses, the research team identified an unexpected composition, initially attributed to a more common mineral such as pyroxene. Further investigations, carried out using specialised instruments, made it possible to recognise the presence of garnet.

The discovery could point to the existence of a previously unknown type of Martian rock, formed through metamorphic or metasomatic processes, or through new forms of magmatic differentiation. The authors of the study, however, remain cautious: further investigations will be required, particularly into the isotopic signatures of the sample, to establish whether the garnet actually formed on Mars or whether it has an “extra-Martian” origin, linked to a celestial body that was later incorporated into the planet’s surface.

Ana Černok’s contribution focused on the mineralogical and geochemical interpretation of the sample, drawing on her expertise in the study of meteorites and planetary materials. The scientific collaboration originated within the doctoral research of the first author, Tanya Kizovski, then based at the Royal Ontario Museum in Toronto and now a faculty member at Brock University. Černok contributed to this work as a member of the supervisory team and as a scientific mentor.

“If chemical elements are the letters of the alphabet, then minerals are the words through which planets tell their story,” explains Ana Černok. “Discovering a new mineral on another world is like finding a lost word from an ancient language. Garnet tells us that Mars experienced more complex geological processes than we previously thought, adding a new piece to the story of its evolution.”

The work is the result of an international collaboration involving institutions from Canada, the United Kingdom and Italy, including Brock University, the Royal Ontario Museum, the University of Toronto, the University of Portsmouth, The Open University and the University of Trieste.

A study published in Annals of the New York Academy of Sciences has unexpectedly found that rhythmic passive movements, such as rocking or carrying-like motions, can change the emotional state of domestic chicks, inducing both calming and pleasurable responses. The study, conducted by Cinzia Chiandetti, Andrea Dissegna and Paolo Gallina from the University of Trieste, and Lorenzo Scalera from the University of Udine, investigates the effects of rhythmic motion in animals outside the mammalian class.

In mammals, slow rhythmic passive motion has long been recognized as an important component of parental care: it can reduce crying, lower heart rate and promote sleep. In humans, anecdotal observations also suggest that faster rhythmic movements in babies and young children, such as playful tossing in the air, swinging or rides such as roller coasters, can elicit pleasure and excitement.

To test whether these effects also occur outside mammals, and to understand when motion shifts from a primarily calming function to a potentially pleasurable one, the research team observed domestic chicks while they were being rocked. The use of chicks to study this phenomenon is unprecedented: these animals are able to walk immediately after hatching and, unlike mammalian infants, are not carried by their mother.

During the experiment, individual chicks were placed inside an opaque box attached to a precision robotic arm, programmed to reproduce rocking and carrying-like motions while varying their frequency — slow or fast — and direction — horizontal or vertical. The animals’ emotional state was monitored non-invasively by recording their vocalizations.

The results show that slow rocking and slow carrying-like movements reduce so-called “contact calls”, vocalizations associated with discomfort, isolation or separation. This finding mirrors the calming effects of maternal carrying already documented in mammals.

A particularly significant result, however, concerns the possibility that specific forms of rhythmic movement can also induce a positive response. When the chicks were exposed to fast horizontal rocking or fast carrying-like movements, they emitted a significantly higher number of affiliative vocalizations — so-called brood calls — which are usually produced in safe and socially positive contexts and are considered indicators of a pleasurable state.

Taken together, the findings suggest that the calming effects of carrying and rocking observed in mammals may stem from a widespread sensitivity to rhythm and motion in animals.

As the study’s authors note: “Our findings expand the functional scope of rhythmic stimulation, positioning it as a regulator of affect with both calming and pleasurable dimensions across vertebrate lineages.”

Because chicks do not experience maternal carrying in their natural history, their sensitivity to rhythmic movement appears to reflect a deeply conserved mechanism across vertebrates, rather than a response to specific parental care strategies.
