Frontiere della Transizione Energetica. Un database cartografico sui permessi di ricerca per materie prime critiche in Italia.
<p>La principale strategia istituzionale per limitare il riscaldamento globale e realizzare un futuro a bassa intensità di carbonio si risolve, ad oggi, nella transizione a forme di energia "pulite". Le tecnologie di base di questa transizione come batterie ricaricabili, pannelli solari e turbine eoliche sono tuttavia caratterizzate da un'alta intensità minerale, ossia dalla necessità di reperire alcune materie prime in nuove e ben più ingenti quantità rispetto a precedenti cicli di accumulazione. All'interno dell'Eurozona, la sostanziale dipendenza dalle importazioni di CRM ha prodotto un forte stimolo all'esplorazione di risorse minerarie indigene tramite, per esempio, il Raw Materials Act (2023) ed altre iniziative comunitarie. All'interno di questo scenario europeo, già si assiste ad una significativa espansione delle concessioni per permessi di ricerca mineraria in diversi territori della penisola italiana. Al di là dei casi isolati è però complicato tracciare un quadro d'insieme di questa espansione. Almeno due fattori concorrono a rendere difficoltosa questa informazione: da un lato, la scarsa consapevolezza rispetto alla reale intensità minerale della transizione energetica e quindi la sostanziale mancanza di un dibattito tanto pubblico quanto accademico, dall'altro dalla straordinaria frammentazione istituzionale che caratterizza la gestione delle risorse minerarie in Italia, la cui autorizzazione spetta alle Regioni. Questo dataset sopperisce a questa mancanza. Sono qui raccolti e progressivamente aggiornati i dati cartografici relativi ai permessi di ricerca mineraria per materie prime critiche (CRM) ad oggi attivi in Italia, con l'obiettivo di rendere unitari, leggibili e accessibili i dati geografici relativi a queste concessioni. I dati raccolti sono di pubblico dominio e reperiti nelle diverse banche dati regionali. Ad ogni poligono sono associati alcuni indicatori di tipo qualitativo e quantitativo. In conclusione, questo dataset risponde alla necessità di tracciare le dimensioni geografiche di un fenomeno emergente che, data la sua fase iniziale di sviluppo, è ancora poco leggibile dal punto di vista materiale pur promettendo trasformazioni di ampio raggio su ecosistemi e società locali.</p>
Island-specific evolution of a sex-primed autosome in the planarian Schmidtea mediterranea
<p>The sexual strain of the planarian <em>Schmidtea mediterranea </em>is a hermaphrodite indigenous to Tunisia and several Mediterranean islands. Here, we isolated individual chromosomes and used sequencing, Hi-C and linkage mapping to assemble a chromosome-scale genome reference. The linkage map revealed an extremely low rate of recombination on chromosome 1. We confirmed suppression of recombination on chromosome 1 by genotyping of individual sperm and oocytes. We showed that previously identified genomic regions that maintain heterozygosity even after prolonged inbreeding comprise essentially all of chromosome 1. Genome sequencing of individuals isolated in the wild indicated that this phenomenon has evolved specifically in populations from Sardinia and Corsica. We found that most known master regulators of the reproductive system are located on chromosome 1. We used RNA interference to knock down a gene with haplotype-biased expression and observed that this led to the formation of a more pronounced female mating organ. Based on these observations, we propose that chromosome 1 is a sex-primed autosome primed for evolution into a sex chromosome.</p>
GeoERA RESOURCE H3O-PLUS data set which contains hydraulic properties of prime aquifers and aquitards in the Dutch-Flemish-German cross-border area
<p>Dataset which contains information about hydraulic properties of harmonized hydrogeological units in the Dutch-Flemish-German cross-border region which was compiled in the GeoERA RESOURCE project under WP3 H3O-PLUS. The harmonization of the 3D geometry of the cross-border hydrogeological units in the H3O projects constituted a major step towards a common hydrogeological dataset of the Roer Valley Graben and thus the harmonization of groundwater flow models. The database that was compiled provides the characterization of these hydrogeological units with respect to their hydraulic properties, primarily their hydraulic conductivity.<br> The associated report and appendices describe the database of hydraulic properties of aquifers and aquitards based on common criteria. Attention is also given to the characterization of hydraulic properties of faults.</p>
Smooth numbers in large prime gaps
<p><strong>Overview</strong></p> <p>This dataset contains numbers from 25 up to 1 quadrillion (10<sup>15</sup>) that are smooth relative to the gap to the preceding prime. More precisely, we list all numbers <em>n</em> so that</p> <p> <em>r</em> + <em>p<sup>a</sup></em> ≤ <em>n</em></p> <p>where <em>r</em> is the largest prime smaller than <em>n</em> - 1, and <em>p<sup>a</sup></em> is the largest prime-power divisor of <em>n</em>. The dataset is the result of a 10 day computation using 15 cores on an Intel Xeon system, running code hosted at <a href="https://github.com/RussWoodroofe/invgen">GitHub</a> (see "Related identifiers"). The GitHub code checks additional conditions when <em>r</em> is <em>n</em> - 2 and <em>n </em>- 1 is a power of 2, but it is easy and quick to check that when (up to 10<sup>15</sup>) <em>n</em> = 2<sup><em>k</em></sup> + 1, the second largest prime <em>r<sub>2</sub></em> satisfies <em>r<sub>2</sub></em> + <em>p<sup>a</sup></em> > n. Thus, this additional check makes no difference in the output.</p> <p>Our motivations for computing this data are described in our paper <em>On invariable generation of alternating groups by elements of prime and prime power order</em> (<a href="http://arxiv.org/abs/2201.12371">arXiv:2201.12371</a>). Any number <em>n</em> in the range which is not of the given form has the associated alternating group <em>A<sub>n</sub></em> generated by any element of order <em>r</em> together with any element having a certain cycle structure (and of order <em>p<sup>a</sup></em>).</p> <p><strong>Description / specification</strong></p> <p>The data is stored as compressed text-based input to a computer algebra system, specifically in gzipped <a href="https://www.gap-system.org/">GAP</a> format. The file out-<em>k</em>.g.gz holds numbers in the range from (<em>k </em>- 1)⋅10<sup>12</sup> to <em>k</em>⋅10<sup>12</sup>. The first line of each file sets the variable invgen_oversmooth_range to be the range (thus, [(<em>k </em>- 1)⋅10<sup>12</sup> .. <em>k</em>⋅10<sup>12</sup>]). The subsequent lines set invgen_oversmooth to a list of pairs of numbers [<em>n</em>, <em>p<sup>a</sup></em>], where <em>n</em> is a smooth number as described above, and <em>p<sup>a</sup></em> is the largest prime-power of <em>n</em>. The largest prime preceding <em>n</em> - 1 is given in a GAP comment.</p> <p>Thus, the first few lines of out-0.g.gz (when uncompressed) appear as</p> <pre><code>invgen_oversmooth_range:=[25..1000000000000]; invgen_oversmooth := [ [ 30, 5 ], # bp 23 [ 60, 5 ], # bp 53 [ 126, 9 ], # bp 113 [ 210, 7 ], # bp 199 [ 252, 9 ], # bp 241 [ 308, 11 ], # bp 293 [ 330, 11 ], # bp 317 [ 420, 7 ], # bp 409 ...</code></pre> <p>where [25 .. 1000000000000] is the range considered, and for example "[ 30, 5 ], # bp 23" represents that 23 is the largest prime preceding 30 - 1, 5 is the largest prime-power divisor of 30, and 23 + 5 ≤ 30.</p> <p>We created the data in GAP files for ease of inputting into a GAP program in our own use of the data. It is easy to convert the GAP files to another format via standard technique such as regular expression-based search and replace. For example, on macOS or Linux, the following command will convert the list in out-0.g.gz to a CSV file, which it will display on the terminal.</p> <pre><code class="language-bash">zcat out_quadrillion/out-0.g.gz | sed -En 's/ \[ ([0-9]+), ([0-9]+) \], # bp ([0-9]+)/\1,\2,\3/gp' | less</code></pre> <p> </p>

WHY Toolkit plug-in tables for PRIMES and TIAM-ECN
<p>Plug-in tables for the PRIMES and TIAM-ECN models, generated using the WHY Toolkit. These data represent estimates of energy consumption subdivided by energy service, energy carrier, country, building type, building age, renovation status and temporal unit. The outputs of the WHY toolkit are expressed as energy per building. For each service-carrier combination, the data delivered by the WHY toolkit represent the amount of carrier (in terms of kWh input) that would be needed if this carrier were to fulfill the whole service demand for each combination of building type, construction period and renovation status. A detailed description of the data and how they can be used in energy system models is available in deliverable D4.2 of the WHY project, which can be found in the following webpage: <a href="https://www.why-h2020.eu/materials/articles-and-reports">Articles and reports: WHY H2020 Project (why-h2020.eu</a> </p>
Data and code for: Acute heat priming promotes short-term climate resilience of early life stages in a model sea anemone
<p>Across diverse taxa, sublethal exposure to abiotic stressors early in life can lead to benefits such as increased stress tolerance upon repeat exposure. This phenomenon, known as hormetic priming, is largely unexplored in early life stages of marine invertebrates, which are increasingly threatened by anthropogenic climate change. To investigate this phenomenon, larvae of the sea anemone and model marine invertebrate <em>Nematostella vectensis</em> were exposed to control (18°C) or elevated (24°C, 30°C, 35°C, or 39°C) temperatures for 1 hour at 3 days post-fertilization (DPF), followed by return to control temperatures (18°C). The animals were then assessed for growth, development, metabolic rates, and heat tolerance at 4, 7, and 11 DPF. Priming at intermediately elevated temperatures (24°C, 30°C, or 35°C) augmented growth and development compared to controls or priming at 39°C. Indeed, priming at 39°C hampered developmental progression, with around 40% of larvae still in the planula stage at 11 DPF, in contrast to 0% for all other groups. Total protein content, a proxy for biomass, and respiration rates were not significantly affected by priming, suggesting metabolic resilience. Heat tolerance was quantified with acute heat stress exposures, and was significantly higher for animals primed at intermediate temperatures (24°C, 30°C, or 35°C) compared to controls or those primed at 39°C at all time points. To investigate a possible molecular mechanism for observed changes in heat tolerance, the expression of heat shock protein 70 (HSP70) was quantified at 11 DPF. Expression of HSP70 significantly increased with increasing priming temperature, with the presence of a doublet band for larvae primed at 39°C, suggesting persistent negative effects of priming on protein homeostasis. Interestingly, primed larvae in a second cohort cultured to 6 weeks post-fertilization continued to display hormetic growth responses, whereas benefits for heat tolerance were lost; in contrast, negative effects of short-term exposure to extreme heat stress (39°C) persisted. These results demonstrate that some dose-dependent effects of priming waned over time while others persisted, resulting in heterogeneity in organismal performance across ontogeny following priming. Overall, these findings suggest that heat priming may augment the climate resilience of marine invertebrate early life stages via the modulation of key developmental and physiological phenotypes, while also affirming the need to limit further anthropogenic ocean warming.</p>

Raw Data for the article: Changes in the Transcriptome Profiles of Human Amnion-Derived Mesenchymal Stromal/Stem Cells Induced by Three-Dimensional Culture: A Potential Priming Strategy to Improve Their Properties
<p>Mesenchymal stromal/stem cells (MSCs) are believed to function in vivo as a homeostatic tool that shows therapeutic properties for tissue repair/regeneration. Conventionally, these cells are expanded in two-dimensional (2D) cultures, and, in that case, MSCs undergo genotypic/phenotypic changes resulting in a loss of their therapeutic capabilities. Moreover, several clinical trials using MSCs have shown controversial results with moderate/insufficient therapeutic responses. Different priming methods were tested to improve MSC effects, and three-dimensional (3D) culturing techniques were also examined. MSC spheroids display increased therapeutic properties, and, in this context, it is crucial to understand molecular changes underlying spheroid generation. To address these limitations, we performed RNA-seq on human amnion-derived MSCs (hAMSCs) cultured in both 2D and 3D conditions and examined the transcriptome changes associated with hAMSC spheroid formation. We found a large number of 3D culture-sensitive genes and identified selected genes related to 3D hAMSC therapeutic effects. In particular, we observed that these genes can regulate proliferation/differentiation, as well as immunomodulatory and angiogenic processes. We validated RNA-seq results by qRT-PCR and methylome analysis and investigation of secreted factors. Overall, our results showed that hAMSC spheroid culture represents a promising approach to cell-based therapy that could significantly impact hAMSC application in the field of regenerative medicine.</p>
