Chandra and Magellan/FIRE follow-up observations of PSO167–13: An X-ray weak QSO at z = 6.515

This article presents the results of follow-up observations of the z = 6.515 radio-quiet QSO PSO167–13, which is interacting with a close companion galaxy with the goal to confirm the existence of the X-ray source and to investigate the rest-frame UV properties of the QSO. The authors observed the PSO167–13 system with Chandra/ACIS-S (177 ks) and obtained new spectroscopic observations (7.2 h) with Magellan/FIRE.

Do gene-environment interactions play a role in COVID-19 distribution? The case of Alpha-1 Antitrypsin, air pollution and COVID-19 (open access)

Do gene-environment interactions play a role in COVID-19 distribution? The case of Alpha-1 Antitrypsin, air pollution and COVID-19

This article evaluates the role that gene-environment interaction between air-pollution and Alpha-1 Antitrypsin (AAT) genes plays in the severity of COVID-19. Results find parallelism between the number of COVID deaths and the AAT*air pollution global risk in Europe.
