Sono stati pubblicati oggi lunedì 15 agosto, i risultati dell’edizione 2023 dell’Academic Ranking of World Universities (ARWU), elaborato dalla ShanghaiRanking Consultancy, una delle più accreditate agenzie di rating internazionale per la valutazione di Università ed Enti di Ricerca. Quest’anno sono state oltre 2.000 le università scrutinate dall’agenzia asiatica e soltanto le migliori 1.000 sono rientrate in classifica. Ancora una volta l’Università di Padova conferma la sua performance, rimandendo nella fascia tra il 151° e il 200° posto su scala mondiale e sul podio, a livello nazionale, insieme alla Sapienza, l'Università di Milano e l'Università di Pisa.

Il ranking ARWU è elaborato sulla base di sei indicatori: i premi Nobel e le Medaglie Fields di ex studenti (Alumni) o di ricercatori della singola Università (Award), il numero di ricercatori maggiormente citati e affiliati presso l’Ateneo (Hi-Ci), le pubblicazioni su "Nature & Science" (N&S), le pubblicazioni sulle riviste più citate nelle aree tecnico-scientifico e sociale (PUB), più un altro indicatore che rapporta i precedenti cinque parametri allo staff accademico, indicante una produttività pro-capite  (PCP). A trainare il risultato dell’Ateneo Patavino sono stati in particolare i due indicatori relativi alla produttività scientifica (N&S e PUB), con cui Padova consolida il primato nazionale e risulta assai competitiva anche su scala mondiale. Quest’anno migliora anche il parametro relativo al numero di ricercatori “Highly Cited” (Hi-Ci), assicurando all’Ateneo Patavino il primato di eccellenza scientifica a livello nazionale.

Sono stati pubblicati oggi lunedì 15 agosto, i risultati dell’edizione 2023 dell’Academic Ranking of World Universities (ARWU), elaborato dalla ShanghaiRanking Consultancy, una delle più accreditate agenzie di rating internazionale per la valutazione di Università ed Enti di Ricerca. Quest’anno sono state oltre 2.000 le università scrutinate dall’agenzia asiatica e soltanto le migliori 1.000 sono rientrate in classifica. Ancora una volta l’Università di Padova conferma la sua performance, rimandendo nella fascia tra il 151° e il 200° posto su scala mondiale e sul podio, a livello nazionale, insieme alla Sapienza, l'Università di Milano e l'Università di Pisa.

Il ranking ARWU è elaborato sulla base di sei indicatori: i premi Nobel e le Medaglie Fields di ex studenti (Alumni) o di ricercatori della singola Università (Award), il numero di ricercatori maggiormente citati e affiliati presso l’Ateneo (Hi-Ci), le pubblicazioni su "Nature & Science" (N&S), le pubblicazioni sulle riviste più citate nelle aree tecnico-scientifico e sociale (PUB), più un altro indicatore che rapporta i precedenti cinque parametri allo staff accademico, indicante una produttività pro-capite  (PCP). A trainare il risultato dell’Ateneo Patavino sono stati in particolare i due indicatori relativi alla produttività scientifica (N&S e PUB), con cui Padova consolida il primato nazionale e risulta assai competitiva anche su scala mondiale. Quest’anno migliora anche il parametro relativo al numero di ricercatori “Highly Cited” (Hi-Ci), assicurando all’Ateneo Patavino il primato di eccellenza scientifica a livello nazionale.

Published as a breakthrough article in Nucleic Acids Research, the study entitled Genome-wide mapping of i-motifs reveals their association with transcription regulation in live human cells demonstrates that i-motifs (iMs) and G-quadruplexes (G4s) are not only present in live human cells, therefore in non-acidic conditions, they also perform a control function in the expression of cellular genes. These original findings are the results of the work performed by a research team led by Prof Sara Richter of the University of Padua.

As demonstrated by Watson and Crick in 1953, the genetic information of every cell is contained in DNA that forms the double helix structure. Over the years, numerous studies have proved that the structure of DNA is much more dynamic than initially thought. Alternative constructs to the double helix, defined as non-canonical structures, must be assumed. Among these, i-motifs (iMs) and G-quadruplexes (G4s) are four-stranded structures that can form in particular regions of DNA based on their composition. G-quadruplexes (G4s) and i-motifs (iMs) are non-canonical nucleic acid structures, an alternative to the Watson-Crick double-helix conformation.

To date, G4s are characterized much more than iMs are, as it was long believed that they could not be present in cells because their formation only occurred in acidic conditions and test tubes.

First authors of the study Irene Zanin and Emanuela Ruggiero, from the Department of Molecular Medicine of the University of Padua explain, “Our work highlights how the presence of iMs and G4s hold an intrinsic feature of each cell line and therefore how these structures control important cellular functions. Given the involvement in key roles of cell biology, iMs, and G4s represent new therapeutic targets for different and relevant human pathologies, such as cancer, infectious and neurodegenerative diseases.”

G-quadruplexes (G4s) and i-motifs (iMs) are non-canonical nucleic acid structures, an alternative to the Watson-Crick double-helix conformation.

To date, G4s are characterized much more than iMs are, as it was long believed that they could not be present in cells because their formation only occurred in acidic conditions and test tubes.

First authors of the study Irene Zanin and Emanuela Ruggiero, from the Department of Molecular Medicine of the University of Padua explain, “Our work highlights how the presence of iMs and G4s hold an intrinsic feature of each cell line and therefore how these structures control important cellular functions. Given the involvement in key roles of cell biology, iMs, and G4s represent new therapeutic targets for different and relevant human pathologies, such as cancer, infectious and neurodegenerative diseases.”

Published as a breakthrough article in Nucleic Acids Research, the study entitled Genome-wide mapping of i-motifs reveals their association with transcription regulation in live human cells demonstrates that i-motifs (iMs) and G-quadruplexes (G4s) are not only present in live human cells, therefore in non-acidic conditions, they also perform a control function in the expression of cellular genes. These original findings are the results of the work performed by a research team led by Prof Sara Richter of the University of Padua.

As demonstrated by Watson and Crick in 1953, the genetic information of every cell is contained in DNA that forms the double helix structure. Over the years, numerous studies have proved that the structure of DNA is much more dynamic than initially thought.

According to a 1200 year timescale based on tree rings, we are experiencing unprecedented warming. Such finding are the result of the international research team coordinated by Prof Marco Carrer of the University of Padua, and by Georg von Arx of the Swiss Federal Institute for Forest Snow and Landscape Research WSL.

Published as, Fennoscandian tree-ring anatomy shows a warmer modern than medieval climate, the study shows that the Middle Ages and following centuries were less turbulent from a climactic point of view. While we know that the famous "Little Ice Age" occurred, so did the "Medieval Warm Period". The latter represented a phase of unusual warming that had always puzzled researchers.  Climate reconstructions produced with tree rings seemed to indicate even higher temperatures than today but there was no plausible physical explanation for such exceptional warming. Climate models indicated mild but not so high temperatures during this Medieval Warm Period.

Prof Marco Carrer of the University of Padua Department of Land, Environment, Agriculture and Forestry (TeSAF) explains, “Previous climate reconstructions relied on the size or density of tree rings. Such measurements relied on the temperature, while other factors could influence the width or density of a ring. Together with other researchers, we have produced a new climate reconstruction based on an innovative and particularly precise method for extracting information on previous temperatures from trees. Unlike previous work, the new results lead to the same conclusion as climate models. As the Medieval Warm Period, at least for Scandinavia, where the trees studied come from, were found to be colder than previously thought. Current warming is likely outside the range of natural temperature fluctuations witnessed in the past 1200 years.

For this study, researchers measured the cell walls of 50 million cells from 188 living and dead Scotch pines (Pinus sylvestris). Calculating their annual rings covers a period of about 1200 years. Based on these measurements, research then reconstructed summer temperatures in the region and compared them to both regional climate model simulations and previous reconstructions based on annual ring density.

According to a 1200 year timescale based on tree rings, we are experiencing unprecedented warming. Such finding are the result of the international research team coordinated by Prof Marco Carrer of the University of Padua, and by Georg von Arx of the Swiss Federal Institute for Forest Snow and Landscape Research WSL.

Published as, Fennoscandian tree-ring anatomy shows a warmer modern than medieval climate, the study shows that the Middle Ages and following centuries were less turbulent from a climactic point of view. While we know that the famous "Little Ice Age" occurred, so did the "Medieval Warm Period". The latter represented a phase of unusual warming that had always puzzled researchers.  Climate reconstructions produced with tree rings seemed to indicate even higher temperatures than today but there was no plausible physical explanation for such exceptional warming. Climate models indicated mild but not so high temperatures during this Medieval Warm Period.

Prof Marco Carrer of the University of Padua Department of Land, Environment, Agriculture and Forestry (TeSAF) explains, “Previous climate reconstructions relied on the size or density of tree rings. Such measurements relied on the temperature, while other factors could influence the width or density of a ring. Together with other researchers, we have produced a new climate reconstruction based on an innovative and particularly precise method for extracting information on previous temperatures from trees. Unlike previous work, the new results lead to the same conclusion as climate models. As the Medieval Warm Period, at least for Scandinavia, where the trees studied come from, were found to be colder than previously thought. Current warming is likely outside the range of natural temperature fluctuations witnessed in the past 1200 years.

For this study, researchers measured the cell walls of 50 million cells from 188 living and dead Scotch pines (Pinus sylvestris). Calculating their annual rings covers a period of about 1200 years. Based on these measurements, research then reconstructed summer temperatures in the region and compared them to both regional climate model simulations and previous reconstructions based on annual ring density.
