Evaluating the Microbial Habitability of Rogue Planets and Proposing Speculative Scenarios on How They Might Act as Vectors for Panspermia

open access: yesLife, 2021
There are two types of rogue planets, sub-brown dwarfs and “rocky” rogue planets. Sub-brown dwarfs are unlikely to be habitable or even host life, but rocky rogue planets may have a liquid ocean under a thick atmosphere or an ice layer.

On the Habitability of Aquaplanets

open access: yesChallenges, 2014
An Aquatic Habitability Index is proposed, based on Quantitative Habitability Theory, and considering a very general model for life. It is a primary habitability index, measuring habitability for phytoplankton in the first place.

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Human affinity for rivers

open access: yesRiver, 2022
Human civilization prospers along rivers worldwide. Here, we investigated human–river relations by revealing the linkage between water and habitability for human settlements, and socioeconomic and cultural development across China.

A revised lower estimate of ozone columns during Earth’s oxygenated history

open access: yesRoyal Society Open Science, 2022
The history of molecular oxygen (O2) in Earth’s atmosphere is still debated; however, geological evidence supports at least two major episodes where O2 increased by an order of magnitude or more: the Great Oxidation Event (GOE) and the Neoproterozoic ...

Quantifying the influence of coastal flood hazards on building habitability following Hurricane Irma [PDF]

open access: yesNatural Hazards and Earth System Sciences
Appropriate management of coastal flood risk is critical for creating resilient communities. An important part of this is estimating what buildings will become uninhabitable due to a flood event such as a tropical cyclone.

The waterbodies of the halo-volcanic Dallol complex: earth analogs to guide us, where to look for life in the universe

open access: yesFrontiers in Microbiology, 2023
Microbes are the Earth life forms that have the highest degree of adaptability to survive, live, or even proliferate in very hostile environments. It is even stated that microbes can cope with any extreme physico-chemical condition and are, therefore ...

Intact polar lipidome and membrane adaptations of microbial communities inhabiting serpentinite-hosted fluids

open access: yesFrontiers in Microbiology, 2023
The generation of hydrogen and reduced carbon compounds during serpentinization provides sustained energy for microorganisms on Earth, and possibly on other extraterrestrial bodies (e.g., Mars, icy satellites).

Searching for Life, Mindful of Lyfe’s Possibilities

open access: yesLife, 2022
We are embarking on a new age of astrobiology, one in which numerous interplanetary missions and telescopes will be designed, built, and launched with the explicit goal of finding evidence for life beyond Earth.
