“…This was more significant in HIV than in Sindbis virus perhaps for HIV is a retrovirus that exists as a double stranded DNA segment incorporated in the host DNA; however, Sindbis virus needs ds RNA phase in its replication cycle (11). These data, methods and analyses were presented in international and national congresses (12,13).…”

I developed a test to study the probability distribution of bases in dinucleotides separated by 0, 1, 2 ... K nucleotides sites. This analysis define selective profiles of dinucleotides by their sign and selection coefficients, their distance to neutrality measured by a chi-square value and the order of significance of their distance to randomness among the 16 possible values. In double stranded (ds) DNA or RNA an index (index = I, with 5'-3' sense) dinucleotide participates in evolutionary processes together with three dinucleotides defined by base complementarity and 5'-3' sense. The anti-sense dinucleotide in the same strand, the parallel (Par, with 3'-5' sense) and anti-parallel (a-Par, with 5'- 3' sense) dinucleotides in the complementary strand. Single stranded (ss) RNA or DNA do not have these set of dinucleotides and would not present similarities or differences, among those four dinucleotides. I studied viromes taken from GenBank, with ds and ss RNA and DNA by this dinucleotide analysis. The core matrix has rows with Separations (Sep) of bases and columns with their selective profiles of the Index, Par and a-Par dinucleotides. Profiles distances I-Par and I-a-Par where compared. The ds RNA or DNA showed larger selective profiles differences between I-Par than I-a-Par. Ss RNA or DNA viruses showed non-significant differences between these comparisons. Those ss virus that exist as ds virus in their hosts, as Hindbis and HIV virus behaved similarly to ds viruses. Coli phage PhiX174 an ss DNA virus showed smaller I-Par than I-a-Par selective distances.

“…Meteoritics might also represent a pillar in the development of planetary science in Chile and Latin America, as astrobiology is in Mexico (De la Cruz et al., 2020). For instance, the analysis of Chilean meteorites has been focused on different aspects such as (i) Distribution and antiquity (Drouard et al., 2019; Gattacceca et al., 2011; Hutzler et al., 2016), (ii) solar system and planet formation (Pinto et al., 2021), (iii) Education (Pinto et al., 2020), and (iv) Protection of natural heritage (Valenzuela & Benado, 2018). The emergence of meteoritics in Chile appears related to the increased number of meteorites found in hot deserts (Bevan, 2006; Scherer & Delisle, 1992).…”

In 2019, while launching a multidisciplinary research project aimed at developing the Puna de Atacama region as a natural laboratory, investigators at the University of Atacama (Chile) conducted a bibliographic search identifying previously studied geographic points of the region and of potential interest for planetary science and astrobiology research. This preliminary work highlighted a significant absence of local institutional involvement in international publications. In light of this, a follow-up study was conducted to confirm or refute these first impressions, by comparing the search in two bibliographic databases: Web of Science and Scopus. The results show that almost 60% of the publications based directly on data from the Puna, the Altiplano, or the Atacama Desert with objectives related to planetary science or astrobiology do not include any local institutional partner (Argentina, Bolivia, Chile, and Peru). Indeed, and beyond the ethical questioning of international collaborations, Latin-American planetary science deserves a strategic structuring, networking, as well as a road map at national and continental scales, not only to enhance research, development, and innovation, but also to protect an exceptional natural heritage sampling extreme environmental niches on Earth. Examples of successful international collaborations such as the field of meteorites, terrestrial analogs, and space exploration in Chile or astrobiology in Mexico are given as illustrations and possible directions to follow to develop planetary science in South America. To promote appropriate scientific practices involving local researchers, possible responses at academic and institutional levels will eventually be discussed.
