The Design of a Bioinspired Integrated Total Habitability Instrument for Planetary Exploration: A Review of Potential Sensing Technologies [PDF]
BiomimeticsOne key objective of astrobiology is to investigate and discover if other planetary bodies are habitable. The determination of whether an environment is habitable to known life requires measuring liquid water, CHNOPS elements, other nutrients, and energy

Multiverse Predictions for Habitability: The Number of Stars and Their Properties
Universe, 2019 In a multiverse setting, we expect to be situated in a universe that is exceptionally good at producing life. Though the conditions for what life needs to arise and thrive are currently unknown, many will be tested in the coming decades.

Multiverse Predictions for Habitability: Fraction of Life That Develops Intelligence
Universe, 2019 Do mass extinctions affect the development of intelligence? If so, we may expect to be in a universe that is exceptionally placid. We consider the effects of impacts, supervolcanoes, global glaciations, and nearby gamma ray bursts, and how their rates ...

Growth, physiology, and metabolism of Halomonas meridiana in aqueous ammonium sulfate with implications for icy moon astrobiology [PDF]
Frontiers in MicrobiologyThe discovery of extraterrestrial reservoirs of liquid water has motivated missions to icy moons Europa and Titan. Tentative evidence of ammonium sulfate ((NH4)2SO4) has been detected on the surface of Europa, and (NH4)2SO4 could be a prominent ...

Current Biology, 2017 What is a habit? One problem with the concept of habit has been that virtually everyone has their own ideas of what is meant by such a term. Whilst not eschewing folk psychology, it is useful to re-examine dictionary definitions of 'habit'. The Oxford Dictionary of English defines habit as "a settled or regular tendency or practice, especially one that

Multiverse Predictions for Habitability: Stellar and Atmospheric Habitability
Universe, 2022 Stellar activity and planetary atmospheric properties have the potential to strongly influence habitability. To date, neither have been adequately studied in the multiverse context, so there has been no assessment of how these effects impact the ...

Hard rock dark biosphere and habitability
Frontiers in Astronomy and Space Sciences, 2023 The discovery that most of the prokaryotic diversity and biomass on Earth resides in the deep subsurface, calls for an improved definition of habitability, which should consider the existence of dark biospheres in other planets and moons of the Solar ...

IDC theory: habit and the habit loop [PDF]
Research and Practice in Technology Enhanced Learning, 2020 AbstractInterest-driven creator (IDC) theory is a design theory that intends to inform the design of future education in Asia. It consists of three anchored concepts, namely, interest, creation, and habit. This paper presents the third anchored concept habit as well as the habit loop.

frontiers in Neuroscience, 2008 The neural circuits involved in learning and executing goal-directed actions, which are governed by action-outcome contingencies and sensitive to changes in the expected value of the outcome, have been shown to be different from those mediating habits, which are less dependent on action-outcome relations and changes in outcome value. Extended training,

Modeling Virus and Bacteria Populations in Europa’s Subsurface Ocean
Life, 2022 The search for life in the universe is often informed by the study of “extreme” environments on Earth, which provide analogs for habitable locations in the Solar System, and whose microbial inhabitants may therefore also serve as analogs for potential ...
