Genomic Sovereignty and "The Mexican Genome"

ABSTRACT This PhD seeks to explore the development of a bio-molecular (i.e., genomic) map as a sovereign resource in Mexico. The basic analytical thread of the dissertation is related to the circulation of genomic variability through the policy/legal and scientific social worlds that compose the Mexican medical-population genomics arena. It follows the construction of the Mexican Institute of Genomic Medicine (INMEGEN), the notion of genomic sovereignty, and the Mexican Genome Diversity Project (MGDP).The key argument for the construction of the INMEGEN relied in a nationalist policy framing, which considered the Mexican genome as a sovereign resource, coupling Mexican “uniqueness” to the very nature of genomic science. Nevertheless, the notion of genomic sovereignty was nothing similar to a paradigm, and was not based on shared visions of causality, since the very “nature” of the policy object —Mexican Genome— was, and still is, a disputed reality. It was through the rhetoric upon independence, emancipation and biopiracy: i.e. experiences of dispossession “in archaeology, botany or zoology” (IFS 2001: 25) that the novelty of population genomics became amenable to be understood as a sovereign matter. Therefore, the strategic reification of Mexicanhood fuelled the whole policy and the legal agenda of the INMEGEN as well, which permitted cooperation without consensus and opened the process of policy innovation. Conversely, scientists considered genomic sovereignty an unfounded exaggeration, but anyhow they cooperated and even created a new policy and scientific enterprise. Genomic sovereignty exemplifies the process of cooperation without consensus on its most extreme version .So, as the notion circulated and gradually became a law to protect Mexican genomic patrimony, the initial coalition of scientists, lawyers and policy makers disaggregated. Many of the original members of the coalition now think of genomic sovereignty as a strategy of the INMEGEN to monopolise genomic research in the country. This dissertation additionally explores the way in which the MGDP is constructed in mass media, in INMEGEN´s communication and in the laboratory practices. These different dimensions of the MGDP depict the difficulties that emerge between the probabilistic, relative and multiple constructions of population genomics and the rhetorical strategies to continually assert the existence of the unique “Mexican Genome”. I argue that the Mexican case study provides an entry point to what I and others (Benjamin 2009; Schwartz-Marin 2011) have identified as a postcolonial biopolitics in which the nation state is reasserted rather than diluted. However the relation between sovereignty, race and nation is not mediated by the biological purification of the nation (Agamben 1998; Foucault 2007), or the active participation of citizens looking to increase their vitality (Rose 2008, Rose & Rabinow 2006), but on an awareness of subalternity in the genomic arena and a collective desire to compete in the biomedical global economy.CONACY

Building the genomic nation: ‘Homo Brasilis’ and the ‘Genoma Mexicano’ in comparative cultural perspective

This article explores the relationship between genetic research, nationalism and the construction of collective social identities in Latin America. It makes a comparative analysis of two research projects – the ‘Genoma Mexicano’ and the ‘Homo Brasilis’ – both of which sought to establish national and genetic profiles. Both have reproduced and strengthened the idea of their respective nations of focus, incorporating biological elements into debates on social identities. Also, both have placed the unifying figure of the mestizo/mestiço at the heart of national identity constructions, and in so doing have displaced alternative identity categories, such as those based on race. However, having been developed in different national contexts, these projects have had distinct scientific and social trajectories: in Mexico, the genomic mestizo is mobilized mainly in relation to health, while in Brazil the key arena is that of race. We show the importance of the nation as a frame for mobilizing genetic data in public policy debates, and demonstrate how race comes in and out of focus in different Latin American national contexts of genomic research, while never completely disappearing

Search for eccentric black hole coalescences during the third observing run of LIGO and Virgo

Despite the growing number of confident binary black hole coalescences observed through gravitational waves so far, the astrophysical origin of these binaries remains uncertain. Orbital eccentricity is one of the clearest tracers of binary formation channels. Identifying binary eccentricity, however, remains challenging due to the limited availability of gravitational waveforms that include effects of eccentricity. Here, we present observational results for a waveform-independent search sensitive to eccentric black hole coalescences, covering the third observing run (O3) of the LIGO and Virgo detectors. We identified no new high-significance candidates beyond those that were already identified with searches focusing on quasi-circular binaries. We determine the sensitivity of our search to high-mass (total mass M>70 M⊙) binaries covering eccentricities up to 0.3 at 15 Hz orbital frequency, and use this to compare model predictions to search results. Assuming all detections are indeed quasi-circular, for our fiducial population model, we place an upper limit for the merger rate density of high-mass binaries with eccentricities 0<e≤0.3 at 0.33 Gpc−3 yr−1 at 90\% confidence level

Ultralight vector dark matter search using data from the KAGRA O3GK run

Among the various candidates for dark matter (DM), ultralight vector DM can be probed by laser interferometric gravitational wave detectors through the measurement of oscillating length changes in the arm cavities. In this context, KAGRA has a unique feature due to differing compositions of its mirrors, enhancing the signal of vector DM in the length change in the auxiliary channels. Here we present the result of a search for U(1)B−L gauge boson DM using the KAGRA data from auxiliary length channels during the first joint observation run together with GEO600. By applying our search pipeline, which takes into account the stochastic nature of ultralight DM, upper bounds on the coupling strength between the U(1)B−L gauge boson and ordinary matter are obtained for a range of DM masses. While our constraints are less stringent than those derived from previous experiments, this study demonstrates the applicability of our method to the lower-mass vector DM search, which is made difficult in this measurement by the short observation time compared to the auto-correlation time scale of DM

Explaining the visible and the invisible: ancestry, appearance, race and genetics in Colombia

Using data from focus groups conducted in Colombia, we explore how educated lay audiences faced with scenarios about ancestry and genetics draw on widespread and dominant notions of nation, race and belonging in Colombia to ascribe ancestry to collectivities and to themselves as individuals. People from a life sciences background tend to deploy idioms of race and genetics more readily than people from a humanities and race-critical background. When they considered individuals, people tempered or domesticated the more mechanistic explanations about racialized physical appearance, ancestry and genetics that were apparent at the collective level. Ideas of the latency and manifestation of invisible traits were an aspect of this domestication. People ceded ultimate authority to genetic science, but deployed it to work alongside what they already knew. Notions of genetic essentialism co-exist with the strategic use of genetic ancestry in ways that both fix and unfix race. Our data indicate the importance of attending to the different epistemological stances through which people define authoritative knowledge and to the importance of distinguishing the scale of resolution at which the question of diversity is being posed
