Each recent report of liquid water existing elsewhere in the Solar System has reverberated through the international press and excited the imagination of humankind. Why? Because in the past few decades we have come to realize that where there is liquid water on Earth, virtually no matter what the physical conditions, there is life. What we previously thought of as insurmountable physical and chemical barriers to life, we now see as yet another niche harbouring 'extremophiles'. This realization…

Mini-Review: Probing the limits of extremophilic life in extraterrestrial environment-simulated experiments
Abstract Astrobiology is a relatively recent scientific field that seeks to understand the origin and dynamics of life in the Universe. Several hypotheses have been proposed to explain life in the
Photosynthesis in Extreme Environments
TLDR
Broadening the knowledge both of the range of environments on Earth that are inhabitable by microbes and of their adaptation to these habitats will be critical for understanding how life might have established itself and survived.
13 Photosynthesis in Extreme Environments
Our ongoing exploration of Earth has led to continued discoveries of life in environments that have been previously considered uninhabitable. For example, we find thriving communities in the boiling
Life on the Edge: A Study of Cryobiosis in the Tardigrada
The search for life on other planets has brought with it a renewed interest in the study of extremophiles as it relates to cold-tolerance. The means for the elucidation of these studies has been
Living at the Extremes: Extremophiles and the Limits of Life in a Planetary Context
TLDR
The current state of knowledge for the biospace in which life operates on Earth is reviewed and discussed in a planetary context, highlighting knowledge gaps and areas of opportunity.
The Geology and Habitability of Terrestrial Planets: Fundamental Requirements for Life
Abstract The current approach to the study of the origin of life and to the search for life elsewhere is based on two assumptions. First, life is a purely physical phenomenon closely linked to
Pathways to Life on Earth and Other Planetary Bodies
“Are we alone?” or “Is Anybody Out There?” have been permanent quandaries among mankind from the ancient times to now. In this book, we are discussing the diversity of life on Earth and possibly on
The Adaptability of Life on Earth and the Diversity of Planetary Habitats
TLDR
The adaptability of life as the authors know it is reviewed, especially regarding temperature, pressure, and water activity and the range of possible habitable environments for alien planets and moons is outlined and a variety of planetary environment types are distinguished.
The Early Record of Life
Over the last 3.5 Gyr, the biosphere has had a profound influence on the atmosphere, hydrosphere, and lithosphere, at or near the Earth's surface. However, the conditions when life originated were
The Role of Oceans in the Origin of Life and in Biological Evolution
Abstract This chapter begins with a brief general introduction, which includes the origin of single-cell organisms in oceans, extinction events that affected life on Earth, a clue to life on Earth at

Earth analogs for Martian life. Microbes in evaporites, a new model system for life on Mars.
TLDR
It is proposed that evaporites are thought to occur on Mars and can attenuate light in the UV range while being far more transparent to radiation useful for photosynthesis, and because of the properties of these "endoevaporitic" organisms such communities provide a new model system for studying potential life on Mars.
Extremophile microorganisms as cell factories: support from the European Union
TLDR
The unique characteristics of extremophiles provide virtually unlimited potential for biotechnological applications and have added a new dimension to biodiversity and have encouraged additional efforts and interest to explore what is considered the last frontier of life.
Was the environment for primordial life hypersaline?
  • I. Dundas
  • Environmental Science, Medicine
    Extremophiles
  • 1998
TLDR
The erosion of the monumental central dogma for genetic information makes it attractive to search for life “as the authors don’t know it,” i.e., life-forms without developed DNA as its source of genetic information.
The Ecology of Deep-Sea Hydrothermal Vents
TLDR
The book concludes by exploring the possibility that life originated at hydrothermal vents, a hypothesis that has had tremendous impact on ideas about the potential for life on other planets or planetary bodies in the authors' solar system.
Desiccation tolerance of prokaryotes.
  • M. Potts
  • Biology, Medicine
    Microbiological reviews
  • 1994
TLDR
The present review considers a number of the features that appear to be critical to the withstanding of a long-term water deficit, including the elaboration of a conspicuous extracellular glycan, synthesis of abundant UV-absorbing pigments, and maintenance of protein stability and structural integrity.
Microbial diversity of soda lakes
TLDR
Although present-day soda lakes are geologically quite recent, they have probably existed since archaean times, permitting the evolution of independent communities of alkaliphiles since an early period in the Earth's history.
Energy for microbial life on Europa
TLDR
It is shown that disequilibrium chemistry in the ocean's ice cover, driven by charged particles accelerated in Jupiter's magnetosphere, should produce enough organic and oxidant molecules to fuel a substantial Europan biosphere.
The search for organic substances and inorganic volatile compounds in the surface of Mars
A total of four Martian samples, one surface and one subsurface sample at each of the two Viking landing sites, Chryse Planitia and Utopia Planitia, have been analyzed for organic compounds by a gas
Toward a molecular understanding of cold activity of enzymes from psychrophiles
TLDR
This review highlights initial successes in engineering genetically improved thermal stability in cold-active enzymes to give improved catalysts for low-temperature biotechnology, and highlights how different adaptations are used by different enzymes to achieve conformational flexibility at low temperatures.
Barophiles: deep-sea microorganisms adapted to an extreme environment.
  • K. Horikoshi
  • Biology, Medicine
    Current opinion in microbiology
  • 1998
TLDR
Research on the physiology and molecular biology of deep-sea barophilic bacteria has identified pressure-regulated operons and shown that microbial growth is influenced by the relationship between temperature and pressure in the deep- sea environment.
