The paper ‘The potential of histories as a form of counter-accounting’, published in 2023, has won the prestigious ‘Best 2023 International Scientific Paper’ award by the Italian Society of Professors of Accounting and Business Economics (Società Italiana dei Docenti di Ragioneria e di Economia Aziendale – SIDREA). It was written by Eleonora Masiero, Lecturer and Researcher in Business Economics at UniTS, and Riccardo Stacchezzini and Alessandro Lai, Full Professors at the University of Verona.

This study explores the unconventional accounting activity carried out by the director and accountant of a late 19th-century children's home. The activity challenged dominant discourses and highlighted their weaknesses. The study thus contributes to critical accounting research by revealing the potential of genealogical enquiry as an alternative and meaningful tool for analysing and questioning prevailing assumptions, shedding light on the historical and discursive foundations of controversial issues.

The University of Trieste is proud to be a part of the international research team that has discovered a mechanism that could open up new avenues for the treatment of glioblastoma, a particularly aggressive brain tumour. The study, conducted in collaboration between SISSA, IOM-CNR, the University of Trieste, the University Hospital of Udine and GlioGuard S.r.l. and recently published in the journal Molecular Cancer Research, highlights the importance of chloride ion fluxes in the proliferation of tumour cells.

Specifically, the research identified that so-called ‘calcium-dependent chloride channels’ are involved in the regulation of chloride ion fluxes in and out of the cancer cell. These channels act as ‘gates’ and directly influence the division of tumour cells, promoting their proliferation. By using specific substances to block these fluxes, the researchers were able to stop the replication of lab-grown cancer cells, thus identifying a potential target for future therapies.

As part of this project, the group led by Prof. Fabrizia Cesca of the Department of Life Sciences at the University of Trieste studied the effect of specific inhibitors of chlorine channels, such as niflumic acid and carbenoxolone, on cancer cell replication. Experiments have shown that these substances can significantly slow down cell division, paving the way for new therapeutic possibilities for the treatment of glioblastoma.

This research therefore suggests that ionic currents could be an effective target for the development of innovative drugs against glioblastoma. However, given the complexity and heterogeneity of this tumour type, further studies will be needed to verify the effectiveness of such therapies in patients.

Researchers from the Department of Life Sciences at the University of Trieste, in collaboration with the Sapienza University of Rome, have discovered that the preference of animal species, both human and non-human, for consonant sounds would be partly physiologically determined. The hypothesis at the origin of the study, conducted on one hundred and thirty hatchling chicks, is that the constituent elements of musical abilities - of humans and animals - have a biological root, shared between species that are also phylogenetically distant, and do not depend solely on culture and musical experience.

‘Previous research by the University of Trieste had already led to the discovery that chicks, like other species, prefer so-called consonant musical intervals. The latter, in fact, are those that most resemble the sound produced by living beings, while the dissonant ones recall the lesser harmony of environmental sounds,’ explains Andrea Ravignani, professor of general psychology at the Department of Human Neuroscience at the Sapienza University of Rome. ‘At the time, we did not know the reasons for this; today, however, we know – thanks to studies conducted together, the University of Trieste and the Sapienza University of Rome - that consonant intervals are produced in acoustic social signals.’

The research was carried out on one hundred and thirty hatchling chicks; once hatched, the chicks – which do not require any parental care, neither to develop their vocal repertoire nor to walk – were reared for four days, in pairs, in rectangular cages at controlled room temperature. 

The following calls were recorded for each chick in soundproof pens: contact calls emitted by the chick when it feels discomfort because, for example, it is separated from the hen, brooding calls emitted in pleasant situations and food calls emitted when the chick identifies a profitable food source. These calls are part of a complex vocal code that chicks develop from hatching to adulthood to communicate their needs to other conspecifics and to express the positive or negative nature of a situation they are experiencing. 

The researchers stimulated the production of each type of call by the chicks by gradually recreating the natural situation associated with each one. Specifically, they recorded: contact calls, leaving the chicks alone in the empty pen after separating them from their rearing mate and the imprinting object; brood calls, placing an imprinting object in the centre of the pen after initial isolation; food calls, placing a dish of food in the centre of the pen after removing the imprinting object.

After analysing the minimum and maximum peaks of the fundamental frequencies and calculating their ratio, the study revealed a prevalence of perfect consonance in all types of calls, confirming the idea that consonant sounds are intrinsically present in animal communication. The only recorded dissonances were found in situations of particular distress, such as isolation contexts.

‘This research could open up promising applications: a chick that emits a sound with a certain frequency is probably indicating a certain type of situation, and we now know that the most harmonious calls are those emitted in the most pleasant situations,’ explains Cinzia Chiandetti, associate professor of psychobiology at the Department of Life Sciences at the University of Trieste. ‘Depending on the dominance of consonances or dissonances, we will be able to understand the emotional status of the animal associated with the context in which it finds itself: we are not so far from being able to imagine devices capable of recording the calls and returning the level of comfort or stress of the animal in front of us, even of chickens that, as the writer Andrew Lawler would say, are the birds that have nurtured civilisation’ concludes the expert.

Recent observations using the Hubble Space Telescope have revealed a surprisingly large number of black holes in the early universe. This research, led by Professor Matthew Hayes of Stockholm University and published in The Astrophysical Journal Letters, also involved PhD student Vieri Cammelli of the University of Trieste.

The Hubble Space Telescope (HST) is a space telescope launched in 1990 by NASA and the ESA, which continues to provide extraordinary images of the cosmos. One of its most iconic observations, and one of the deepest ever collected in the visible light spectrum, was the Hubble Ultra Deep Field (HUDF), an image of the universe showing galaxies formed not long after the Big Bang.

Twelve years later, the team of researchers again observed this same area of the universe to identify so-called active galactic nuclei, signs of the presence of accreting black holes. Using variations in the brightness of galaxies, numerous black holes housed within them were discovered, many of which formed during the early stages of the universe.

The discovery aligns with results from the James Webb Space Telescope (JWST), a new instrument that continues to push the boundaries of astronomical observations. The JWST, launched in 2021, is capable of observing even more distant objects and providing new information on the birth and growth of black holes.

Vieri Cammelli, a PhD student at the University of Trieste and co-funded by Chalmers University in Gothenburg, played a key role in the analysis of the data: his research, which will form part of his PhD thesis, represents a significant contribution to the understanding of how supermassive black holes formed in the early stages of cosmic evolution.

Tiziano Agostini, Professor of General Psychology at the Department of Life Sciences at the University of Trieste, received the prestigious Wolfgang Metzger Prize during the opening ceremony of the 23rd Scientific Conference of the Society for Gestalt Theory and its Applications (GTA), held at the University of Milan-Bicocca. The award was presented to him for the book ‘Showing Time: Continuous Pictorial Narrative and the Adam and Eve Story - In Memory of Alberto Argenton’, of which he is co-author.

The prize, named after the German psychologist Wolfgang Metzger, is awarded to those who have significantly contributed to the research and application of Gestalt Theory. Gestalt is an interdisciplinary approach that sees the human being as an open system in constant interaction with its environment. It focuses on how we perceive the whole of an experience or phenomenon, rather than its individual parts, emphasising the importance of global perceptual structures. In a nutshell, what we perceive is not a sum of elements, but simply a synthesis of reality.

For Professor Agostini, this award represents not only a personal accolade, but also an important achievement for the Department of Life Sciences at the University of Trieste. This is the second time that the Metzger Prize has been awarded to a lecturer at the University of Trieste: the first to receive it was Gaetano Kanizsa, founder of the Experimental Psychology Laboratory in Trieste, together with Riccardo Luccio in 1987.

With the awarding of Tiziano Agostini, the University of Trieste reaffirms its leading role on the international academic scene, continuing its tradition of excellence in research on the psychology of perception and experience..

An international study co-ordinated by the Interdisciplinary Centre of Nanoscience of Marseille, with the collaboration of organisations and research centres of excellence, including the Biology and Nanotechnology Laboratory of the Department of Engineering and Architecture at the University of Trieste, has synthesised a new antibacterial compound that promises to be an excellent candidate for the fight against antibiotic resistance, a growing global public health problem that still causes millions of deaths worldwide.

‘The main threat is posed by the eskape group of bacteria - comprising the genera Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa and Enterobacter species - because they are particularly virulent and resistant to antibiotics introduced with treatment” explains Sabrina Pricl, one of the study's researchers and associate professor of chemical engineering at the Department of Engineering and Architecture at the University of Trieste. “Hence the need to develop new antibacterial agents that, on the one hand, are able to kill bacteria, on the other, are not toxic to the organisms that take them in and, above all, do not induce the appearance of further drug resistance.’

The molecule synthesised by the researchers - an amphiphilic dendrimer called AD1b - proved highly efficient against all Gram-negative bacteria, including drug-resistant strains such as Escherichia coli and Acinetobacter baumannii.

The compound interacts with the bacterium by an innovative mechanism of action: it binds to the phospholipids of the bacterial membrane, such as phosphatidylglycerol and cardiolipin, causing the destruction of the membrane itself and the consequent collapse of cell metabolism, leading to the death of the bacterium, without damaging healthy cells - even in vivo - and minimising the risk of developing new resistance, a problem that otherwise plagues traditional antibiotics.

In preclinical tests, the molecule demonstrated strong antibacterial activity as well as great safety, with very low toxicity and no haemolytic effect - results later confirmed in in vivo tests. Moreover, after thirty days of exposure to the compound, no resistance was observed; on the contrary, a drastic reduction in the bacterial load in infected animals was observed.

‘This molecule could pave the way for safer and more targeted therapies and thus give an impetus to the treatment of resistant infections: together with its efficacy, in fact, the ability to not induce resistance puts it in pole position to be further developed at the clinical translational level’ explains Professor Sabrina Pricl.

Researchers from the University of Trieste worked on the design of the AD1 molecule and took part in the computational study, using molecular dynamics simulations to study the interaction between AD1b and the bacterial membrane, applying advanced methodologies supported by CINECA's supercomputing resources.

The research project was funded with NRRP funds and was supported by ICSC, the National Research Centre in High-Performance Computing, Big Data and Quantum Computing.
