Translating environments

Far from being inert materials activated by human ingenuity, natural resources come to be made and unmade through ongoing processes of translation, through which they acquire new potentialities and meanings. In this introduction, we review the key concept of translation for anthropology and explore some of its multiple analytical possibilities in the context of human-environment relations. Based on insights offered by the articles in this collection, we propose a twofold definition of environments as both translating subjects and objects of translation. In grounding our analytical definition, we focus on the enactment of material transformations (as the result of both relations of mutual determination with humans and processes of objectification of the environment), the implications of incommensurability and erasure in processes of (attempted) translation, and the indeterminacy that accompanies (re)configurations of materials, relations and values

Here we analyze SARS-CoV-2 reactive T-cell responses in 768 convalescent SARS-CoV-2-infected (cases) and 500 uninfected (controls) Icelanders. The T-cell responses are stable three to eight months after SARS-CoV-2 infection, irrespective of disease severity and even those with the mildest symptoms induce broad and persistent T-cell responses. Robust CD4+ T-cell responses are detected against all measured proteins (M, N, S and S1) while the N protein induces strongest CD8+ T-cell responses. CD4+ T-cell responses correlate with disease severity, humoral responses and age, whereas CD8+ T-cell responses correlate with age and functional antibodies. Further, CD8+ T-cell responses associate with several class I HLA alleles. Our results, provide new insight into HLA restriction of CD8+ T-cell immunity and other factors contributing to heterogeneity of T-cell responses following SARS-CoV-2 infection.Peer reviewe

Multiple transmissions of de novo mutations in families.

DNMs that occur early may result in mosaicism of both somatic and germ cells. Such early mutations can cause recurrence of disease. We scanned 1,007 sibling pairs from 251 families and identified 878 DNMs shared by siblings (ssDNMs) at 448 genomic sites. We estimated DNM recurrence probability based on parental mosaicism, sharing of DNMs among siblings, parent-of-origin, mutation type and genomic position. We detected 57.2% of ssDNMs in the parental blood. The recurrence probability of a DNM decreases by 2.27% per year for paternal DNMs and 1.78% per year for maternal DNMs. Maternal ssDNMs are more likely to be T>C mutations than paternal ssDNMs, and less likely to be C>T mutations. Depending on the properties of the DNM, the recurrence probability ranges from 0.011% to 28.5%. We have launched an online calculator to allow estimation of DNM recurrence probability for research purposes
