Pyropyga julietafierroae sp. nov. (Coleoptera: Lampyridae): Un ejemplo de participación ciudadana en la ciencia
Se presenta la descripción de Pyropyga julietafierroae sp. nov., incluyendo los genitales de la hembra, de modo que es la primera vez que se describen estas estructuras para una hembra del género Pyropyga Motschulsky, 1852. La especie nueva fue descubierta en un ambiente urbanizado de Ciudad Universitaria en la Ciudad de México, lo que aumenta a 13 especies el género Pyropyga, de las cuales ocho se registran en México. Se muestra un mapa de distribución de las especies mexicanas. Además, se comenta sobre la participación de la ciudadanía para la propuesta y elección del nombre científico con la temática “Mujeres Mexicanas Ilustres”, este ejercicio se realiza por primera vez para nombrar una especie de luciérnaga en nuestro país.We present the description of Pyropyga julietafierroae sp. nov., including the female genitalia, so that it is the first time that these structures are described for a female of the genus Pyropyga Motschulsky, 1852. The new species was recovered from the urbanized environment of Ciudad Universitaria, Mexico City. The total number of species for the genus increases to 13, of which, eight are recorded from Mexico. A distribution map of Mexican species is included. Moreover, herein we comment on the citizen involvement for the proposal and choice of the scientific name with the theme “Illustrious Mexican Women”, this is the first time that a dynamic like this is carried out for naming a firefly species in our country
Clonal chromosomal mosaicism and loss of chromosome Y in elderly men increase vulnerability for SARS-CoV-2
The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality

Life cycle and description of the immature stages of a terrestrial firefly endemic to Mexico: Photinus extensus Gorham (Coleoptera, Lampyridae)
The life cycle, morphology, and bionomy of Photinus extensus Gorham, 1881, an endemic species of Mexico, are described. Redescriptions of adults (male and female) are also presented. Larvae were reared to the adult stage from eggs laid by females collected at the El Pedregal de San Ángel Ecological Reserve, south of Mexico City. The activity period of adults of P. extensus begins at the end of July and finishes by the end of August. Females lay between 3 and 198 eggs. Larvae hatch from the eggs after a period of 11 to 71 days, undergo 6 larval instars and a pupal stage in an annual cycle. Morphological characters of the sixth larval instar of P. extensus are compared with those of several other genera assigned to the tribe Photinini. Knowledge of the natural history of firefly larvae is relevant since most species do not feed as adults and therefore depend on resources acquired during the larval stage

Universal Dependencies 2.6
Universal Dependencies is a project that seeks to develop cross-linguistically consistent treebank annotation for many languages, with the goal of facilitating multilingual parser development, cross-lingual learning, and parsing research from a language typology perspective. The annotation scheme is based on (universal) Stanford dependencies (de Marneffe et al., 2006, 2008, 2014), Google universal part-of-speech tags (Petrov et al., 2012), and the Interset interlingua for morphosyntactic tagsets (Zeman, 2008)
