    In this paper, we discuss the importance of gameplay as a valuable tool in citizen sensing initiatives aimed at enabling creative collaboration and civic engagement. We present a review of selected citizen science and civic technologies’ projects highlighting an emerging culture of massive collaborative initiatives that make use of crowdsourcing, enabling users to voluntarily contribute their time, effort and resources towards scientific research and civic issues. Moreover, we discuss how these initiatives could benefit from the inclusion of gameplay in their interaction processes. For that matter, we present a gamified citizen sensing project we are devising for users to enter and retrieve information on commercially available food products which contain ingredients associated with an increased risk of cancer and other diseases. Through gameplay, we expect to crowdsource an open database of potentially unhealthy food products, raising awareness among consumers about the risks of certain artificial additives. Finally, we argue that the use of gamification processes can engage voluntary participation in initiatives aimed at citizenship – including those which demand complex and repetitive tasks for the collection of data – and call for a more ethical, critical, and meaningful use of these new potential technologies, and for greater awareness of our new civic responsibilities

    Anthracological evidence suggests naturalness of Pinus pinaster in inland southwestern Iberia

    The study of well-preserved archaeological charcoals in the pre-Roman Iron Age settlement of Castillejos II (Badajoz, Spain) is used to reconstruct environmental conditions and land-use practices in vegetation landscapes in the southwest of the Iberian Peninsula before the arrival of Roman civilization. The results support that, while evergreen Quercus forests dominated during the Holocene, Pinus pinaster existed as a natural element of southwestern Iberian Peninsula vegetation. Although its presence could be linked to anthropogenic disturbance or fire history, it is suggested that P. pinaster populations survived during the Holocene in the region, mixed with oaks or in monospecific stands in mountain enclaves. This hypothesis contrasts with previous assumptions that P. pinaster was not autochthonous in the area

    Dynamics of early establishment of SARS-CoV-2 VOC Omicron lineages in Minas Gerais, Brazil

    Brazil is one of the nations most affected by Coronavirus disease 2019 (COVID-19). The introduction and establishment of new virus variants can be related to an increase in cases and fatalities. The emergence of Omicron, the most modified SARS-CoV-2 variant, caused alarm for the public health of Brazil. In this study, we examined the effects of the Omicron introduction in Minas Gerais (MG), the second-most populous state of Brazil. A total of 430 Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) samples from November 2021 to June 2022 from Belo Horizonte (BH) city were sequenced. These newly sequenced genomes comprise 72% of all previously available SARS-CoV-2 genomes for the city. Evolutionary analysis of novel viral genomes reveals that a great diversity of Omicron sublineages have circulated in BH, a pattern in-keeping with observations across Brazil more generally. Bayesian phylogeographic reconstructions indicate that this diversity is a product of a large number of international and national importations. As observed previously, São Paulo state is shown as a significant hub for viral spread throughout the country, contributing to around 70% of all viral Omicron introductions detected in MG
