The genetic make-up of an individual contributes to the susceptibility and response to viral infection. Although environmental, clinical and social factors have a role in the chance of exposure to SARS-CoV-2 and the severity of COVID-191,2, host genetics may also be important. Identifying host-specific genetic factors may reveal biological mechanisms of therapeutic relevance and clarify causal relationships of modifiable environmental risk factors for SARS-CoV-2 infection and outcomes. We formed a global network of researchers to investigate the role of human genetics in SARS-CoV-2 infection and COVID-19 severity. Here we describe the results of three genome-wide association meta-analyses that consist of up to 49,562 patients with COVID-19 from 46 studies across 19 countries. We report 13 genome-wide significant loci that are associated with SARS-CoV-2 infection or severe manifestations of COVID-19. Several of these loci correspond to previously documented associations to lung or autoimmune and inflammatory diseases3,4,5,6,7. They also represent potentially actionable mechanisms in response to infection. Mendelian randomization analyses support a causal role for smoking and body-mass index for severe COVID-19 although not for type II diabetes. The identification of novel host genetic factors associated with COVID-19 was made possible by the community of human genetics researchers coming together to prioritize the sharing of data, results, resources and analytical frameworks. This working model of international collaboration underscores what is possible for future genetic discoveries in emerging pandemics, or indeed for any complex human disease.
In the archaeology of Scandinavian Bronze Age rock art, there is a long-standing debate over the function and role of the engraved weapons and warriors. The question can be boiled down to: Are the depicted warriors actual fighters, or are they showmen merely portraying an identity to gain status and power? One of the proposals was that spears are active because they occur in killing scenes and swords are passive because they are mostly depicted sheathed. Discussing recent rock art research on the transformation of petroglyphs, their narrative structure as well as new discoveries of weapon depictions, and confronting this with results from use wear analyses on similar weaponry, this paper sets out to argue that the answers to this problem may not be as straight forward as previously proposed. Instead it is proposed that while there is a concern with showmanship relating to a warrior identity in Scandinavian rock art, it is based on real combat, fighting, and killing. Rock art was used to enhance the stature of warriors and to make narratives more exciting that involve warriors.
