Citizen Science is a rapidly expanding and diversifying field of innovation with significant implications for, and potential benefits to, society, policy, and various academic research areas. This heterogeneity leads currently to a fragmented and not fully coordinated European Citizen Science landscape. The ambition of EU-Citizen.Science is to build, fill, and promote a sustainable platform and mutual learning space providing different tools, best practice examples and relevant scientific outcomes that are collected, curated, and made accessible to different stakeholders, ranging from interested citizens over scientific institutions up to politicians and public media in order to mainstream Citizen Science in Europe. This breakthrough will be pursued through three interconnected lines of activity: (i) coordination of citizen science actions and leveraging of existing resources in the presently fragmented landscape of Citizen Science in Europe, (ii) engagement of quadruple helix stakeholders at all levels (local, national and European), and (iii) creation of a mutual learning space and a set of comprehensive co-designed training modules for the different target audiences. Moreover, following a transparent, open and inclusive approach, EU-Citizen.Science will promote interdisciplinary, cross-border, cross-sector collaboration, and give rise to significant social innovation and new business models through the creation of new partnerships and the provision of novel sustainability-supporting tools. The EU.Citizen.Science project involves 14 partners and 9 third parties, representing 14 European Member States and a variety of stakeholders ranging from universities, NGOs, local authorities, CSOs and natural history museums, along with several other project supporters. Many of the partners are already engaged in other SwafS projects related to RRI, co-creation and citizen science, as well as numerous initiatives at national or local level.

European natural history collections are a critical infrastructure for meeting the most important challenge humans face over the next 30 years – mapping a sustainable future for ourselves and the natural systems on which we depend – and for answering fundamental scientific questions about ecological, evolutionary, and geological processes. Since 2004 SYNTHESYS has been an essential instrument supporting this community, underpinning new ways to access and exploit collections, harmonising policy and providing significant new insights for thousands of researchers, while fostering the development of new approaches to face urgent societal challenges. SYNTHESYS+ is a fourth iteration of this programme, and represents a step change in evolution of this community. For the first time SYNTHESYS+ brings together the European branches of the global natural science organisations (GBIF, TDWG, GGBN and CETAF) with an unprecedented number of collections, to integrate, innovate and internationalise our efforts within the global scientific collections community. Major new developments addressed by SYNTHESYS+ include the delivery of a new virtual access programme, providing digitisation on demand services to a significantly expanded user community; the construction of a European Loans and Visits System (ELViS) providing, for the first time, a unified gateway to accessing digital, physical and molecular collections; and a new data processing platform (the Specimen Data Refinery), applying cutting edge artificial intelligence to dramatically speed up the digital mobilisation of natural history collections. The activities of SYNTHESYS+ form a critical dependency for DiSSCo - the Distributed System of Scientific Collections, which is the European collection communities ESFRI initiative. DiSSCo will undertake the maintenance and sustainability of SYNTHESYS+ products at the end of the programme.

This research project will study the formation of large meteorite impact craters, characterized by central peaks or rings, flat floors and terraced walls. The complex morphology results from the gravity driven collapse of a much deeper and narrower transient cavity. Standard material models fail to explain such a collapse and specific temporary weakening mechanisms have been proposed. The most successful approach, the Acoustic Fluidization (AF) model, relies on the temporary softening of heavily fractured target rocks by means of an acoustic field in the wake of an expanding shock wave originated upon impact. The project aims to (i) constrain the mechanics of large crater collapse, (ii) constrain AF parameters and enhance AF implementation into simulation software (iSALE), (iii) test the revised AF model with planetary case studies. These objectives will be achieved through a multidisciplinary approach: (1) Small-scale impact experiments will use a target of granular material, which will be acoustically fluidized by an external source to mimic the fluid-like rheology of planetary targets during collapse; (2) Numerical models of complex crater formation, which require the AF parameters to be constrained, will be calibrated and validated against experiments and up-scaled to dimensions of natural craters. The originality lies in combining the systematic laboratory experiments with numerical simulations to improve a widely used AF model. The fulfilment of the project will be ensured by the host and partner institutes, and the planned training activities (laboratory and modelling techniques). The results will be disseminated to the scientific community through peer-reviewed papers and conference contributions. The project will foster excellence in Europe by establishing a network of collaborations that will promote high-quality research, inspire the next generation of planetary scientists, and encourage research in interdisciplinary fields like Solar System exploration.

Our understanding of the emergence and dispersal of the earliest tool-making hominins has been revolutionised in the last decade, with sites in eastern Africa and China pushing both events more than half a million years earlier than previously thought. Traditional models linking biological speciation, cultural innovation and migration events with climatic pulses have remained theoretical, and recent discoveries suggest that the picture of the earliest human colonization across the Old World is far more complex, demanding heuristic approaches to understand the biogeography and adaptive behaviours of early humans. This project will be the first substantive attempt to produce a global synthesis of earliest human occupation dynamics by comparing the world’s longest sequences of early archaeological sites, namely eastern Africa and China. Our objective is to understand the alternative evolutionary trajectories adopted by hominins that shared an overarching biological and cultural background, but who faced different climatic and biogeographic challenges and opportunities. The ambition of our global-scale objectives is accompanied by the unmatched quality of our datasets and the ground-breaking perspective we will adopt in their study. Fieldwork in the two most renowned sequences in each region alongside a primary study of additional top-quality assemblages in both subcontinents, will be combined with extensive metadata sets to produce comprehensive views of temporal trends and paleoecological patterns. Our state-of-the-art methodological sets (which combine an exceptionally diverse range of disciplines from geochemistry to niche modelling) and ground-breaking analytical perspective (which considers data from micro-stratigraphy to satellite imaging) will enable us to develop new approaches to challenge established paradigms and produce a new picture of the biogeographic adaptations of early stone-tool makers.
