12 Microbial Life in Brines, Evaporites and Saline Sediments: The Search for Life on Mars
When water on a planet begins to evaporate the dissolved minerals become more concentrated, form a brine, eventually precipitating out of solution...

The Material-Independent Signatures of Life.Forensic Tools of Astrobiology
Biological life is intimately related to the geochemical conditions on Earth and is fit for this planet’s energy flux. It has often been suggested...
-
The Early History of Bioenergy
Energy is most commonly defined as the potential to do work. The maintenance of the living state requires a constant flow of energy through the...

Assembling the Early Puzzle of Life
So far no theory, no approach, no set of formulas, and no blackboard scheme have been found satisfactory in explaining the origin of life. The...
-
Introduction
We summarize the topics presented in this book, and when appropriate we enlighten cross–references among the different topics: high precision and...

Quantum Corrections to Scalar Quintessence Potentials
We give a brief introduction into the formalism of the effective action. We use the effective action to investigate the stability of scalar...

Cosmological Applications of Loop Quantum Gravity
After a brief introduction to classical and quantum gravity we discuss applications of loop quantum gravity in the cosmological realm. This includes...

The Accelerating Universe and Dark Energy: Evidence from Type Ia Supernovae
I discuss the use of Type Ia supernovae (SNe Ia) for cosmological distance determinations. Low-redshift SNe Ia (...
-
Electroweak Baryogenesis and Primordial Hypermagnetic Fields
The origin of the matter-antimatter asymmetry of the universe remains one of the outstanding questions yet to be answered by modern cosmology, and...

The Early History of Bio-Information
In a general sense, the information level of a structure equals the minimum number of instructions needed to specify the structure (Orgel 1973). The...

Infering Annihilation Channels of Neutralinos in Galactic Halos
Applying the microcanonical definition of entropy to a weakly interacting and self–gravitating neutralino gas, we evaluate the change in the local...

5 Global Distribution of Subsurface Water Measured by Mars Odyssey
While the presence of water in minerals of the Martian surface has been known for many years and the storage of ground ice in the past and present...
-
9 Polar Lakes, Streams, and Springs as Analogs for the Hydrological Cycle on Mars
The extensive fluvial features seen on the surface of Mars attest to the stable flow of water on that planet at some time in the past. However the...

8 Water Cycle in the Atmosphere and Shallow Subsurface
The global water cycle on Earth constitutes one of the most relevant components of the terrestrial ecosystem. While the vast majority of terrestrial...

13 Microbiology of Deep-Sea Hydrothermal Vents: Lessons for Mars Exploration
A large proportion of the Earth (70 %) is covered by seas and oceans. Oceanic waters below one kilometre depth constitute the deep-sea, which...
-
6 Polar Caps
The permanent polar caps of Mars constitute the largest known reservoirs of H2O on the planet. The permanent caps are distinguished from the seasonal...

2 Atmospheric Evolution and the History of Water on Mars
The discovery of high concentrations of water-ice just below the Martian surface in polar areas by the Mars Odyssey spacecraft has strengthened the...

The Scalar Field Dark Matter Model: A Braneworld Connection
This work is a review for the progress of the scalar field dark matter (SFDM) hypothesis. Here we outline a possible brane world model justifying the...

Quintessential Inflation at the Maxima of the Potential
There is great interest in understanding a possible late accelerated expansion of the universe. Data suggest that the universe was still decelerating...
