The co-evolution of life and Earth has profoundly transformed global biogeochemical cycles over the past 3.5 billion years.
Climate change is already reshaping global weather patterns and ecosystems around the world. In the long-term, its consequences could range from further substantial increases in the number of extreme weather […]
Nitrogen is vital for all known life. Yet most nitrogen on Earth is in the atmosphere as di-nitrogen gas, which many organisms can’t use. Fortunately, there are microbes that can […]
Terraforming Mars is an age old science fiction concept now worth revisiting through the lens of modern science and technology. This document serves as a summary of contemporary ideas about […]

The black contours indicate where the surface temperature is 50◦ Celsius. [R] Latitude-longitude maps of surface temperature overlaid with the wind field at the bottom layer, and surface precipitation, for ISR = 1580 Wm−2 , which brings the climate to the onset of a runaway greenhouse effect. The minimum surface temperature between the two surface albedo cases is 345 K or 72◦C.Latitude-longitude maps of surface temperature overlaid with the wind field at the bottom layer, and surface precipitation, for ISR = 1580 Wm−2 , which brings the climate to the onset of a runaway greenhouse effect.

Teegarden’s Star b, a nearby terrestrial world receiving an Earth-like instellation, is a prime candidate for next-generation observatories targeting temperate exoplanets in their habitable zones.
Microbial exoenzymes—extracellular enzymes secreted to degrade complex organic polymers— are essential for recycling carbon and nutrients, thus sustaining primary productivity in today’s oceans.
Life on Earth has been shaped by transformative microbial innovations and singularities that redefined planetary systems, from oxygenic photosynthesis to biological nitrogen fixation.
In our galaxy, tens of billions of wet, rocky Earth-like planets orbit in the habitable zones of their host stars.
Rising concentrations of carbon dioxide in the upper atmosphere will change the way geomagnetic storms impact Earth, with potential implications for thousands of orbiting satellites, according to new research led […]
A new study by researchers at Bar-Ilan University has uncovered that certain ocean viruses—specifically RNA viruses—may disrupt how carbon and nutrients are recycled in the ocean, potentially altering the global […]
