An increase in atmospheric pO_(2) has been proposed as a trigger for the Cambrian Explosion at∼539–514 Ma but the mechanistic linkage remains unclear.To gain insights into marine habitability for the Cambrian Explos...
The origin and cycling of volatiles,including water,carbon dioxide,and nitrogen,are fundamental to the very existence of habitable planets.These volatile compounds,often taken for granted,are the lifeblood of planetar...

Atmospheric carbon dioxide and oxygen concentrations are partially linked via the geological cycle of organic carbon(Fig.1A–C;e.g.CO_(2)+H_(2)O↔CH_(2)O+O_(2)).The history of these two biologically active components,c...
Chemical elements in space can be synthesized by stellar nuclear reactors. Studying the dynamics of processes occurring in the stars introduces a concept of the ensemble-averaged stellar reactor. For future interstell...
The possibility of the life origin in the stellar systems, located at a distance of ~200 pc from the solar system, was investigated. The stars, in the spectrums of which C (carbon), O (oxygen), N (nitrogen), and P (ph...
We would like to express our gratitude to the Autonomous University of Baja California(UABC),the Master's and Doctoral Program in Architecture,Urbanism and Design(MyDAUD),as well as the National Council of Science and Technology(Conacyt).The project is linked to the paper:Habitability and post-covid.A study of urban connectivity in public,which has as code:402/3412.This project is internal to the university and it does not have funds.
This study reflects on the impact that the neighborhoods’in-between spaces have on:spatial perception,social interaction,and security.These sites,characterized by their abandonment and deterioration,can also be seen ...

Earth is the only planet known to be habitable,and is also unique with its liquid water,and the operation of plate tectonics.The geological record shows that the habitability of our planet can rapidly recover from maj...
