Most life on Earth will be killed by lack of oxygen in a billion years
One billion years from now, Earth’s atmosphere is projected to contain a million times less oxygen than today, making it uninhabitable to complex aerobic life Source: https://www.newscientist.com/article/2269567-most-life-on-earth-will-be-killed-by-lack-of-oxygen-in-a-billion-years/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…

Can air pollution help us find alien life?
To find alien life in our universe, scientists have considered searches for optical lasers or even giant energy-harvesting structures known as Dyson spheres. Now they’re suggesting a more mundane sort of search, a hunt for air pollution in exoplanet atmospheres. Source: https://earthsky.org/space/can-pollution-help-us-find-alien-life…

Planetary scientists discover evidence for a reduced atmosphere on ancient Mars
Both Earth and Mars currently have oxidising atmospheres, which is why iron-rich materials in daily life develop rust (a common name for iron oxide) during the oxidation reaction of iron and oxygen. The Earth has had an oxidising atmosphere for approximately 2.5 billion years, but before that, the atmosphere of this planet was reducing—there was no rust.

Biotech fit for the Red Planet: New method for growing cyanobacteria under Mars-like conditions
NASA, in collaboration with other leading space agencies, aims to send its first human missions to Mars in the early 2030s, while companies like SpaceX may do so even earlier. Astronauts on Mars will need oxygen, water, food, and other consumables. These will need to be sourced from Mars, because importing them from Earth would be impractical in the long term….
