Life in extreme environments

  title={Life in extreme environments},
  author={Lynn J. Rothschild and Rocco L. Mancinelli},
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

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

Living at the Extremes: Extremophiles and the Limits of Life in a Planetary Context

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.

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

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

Extremophiles in Earth's Deep Seas: A View Toward Life in Exo-Oceans.

Humanity's search for extraterrestrial life is a modern manifestation of the exploratory and curious nature that has led us through millennia of scientific discoveries. With the ongoing exploration

The Adaptability of Life on Earth and the Diversity of Planetary Habitats

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.

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



Extremophile microorganisms as cell factories: support from the European Union

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?

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

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.

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

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

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

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.
