Cryoprotectants and Ice-Binding Proteins
Some bacteria have developed a variety of strategies to survive and colonize extremely cold environments such as the Antarctic and the Arctic. In...
-
Aeromicrobiology
The atmosphere presents one of the most challenging environments on Earth with extreme psychrophilic and oligotrophic conditions. Cloud temperatures...
-
Viruses in Glacial Environments
Viruses play a central role in glacial microbial communities. Prokaryotes in glacial environments support surprisingly large viral communities,...

The Climate of Snow and Ice as Boundary Condition for Microbial Life
The microclimate and structure of snow and ice are a boundary condition as well as a matrix for a large spectrum of microbial life under alpine and...

Chemical Analysis of a “Miller-Type” Complex Prebiotic Broth
We have analyzed the chemical variety obtained by Miller-Urey-type experiments using nuclear magnetic resonance (NMR) spectroscopy and coherent...

An Experimental Framework for Generating Evolvable Chemical Systems in the Laboratory
Most experimental work on the origin of life has focused on either characterizing the chemical synthesis of particular biochemicals and their...

Encapsulation of Nucleic Acids into Giant Unilamellar Vesicles by Freeze-Thaw: a Way Protocells May Form
Protocells are believed to consist of a lipid membrane and encapsulated nucleic acid. As the lipid membrane is impermeable to macromolecules like...

Interaction, at Ambient Temperature and 80 °C, between Minerals and Artificial Seawaters Resembling the Present Ocean Composition and that of 4.0 Billion Years Ago
Probably one of the most important roles played by minerals in the origin of life on Earth was to pre-concentrate biomolecules from the prebiotic...

Can an Imidazole Be Formed from an Alanyl-Seryl-Glycine Tripeptide under Possible Prebiotic Conditions?
The five-membered heterocyclic imidazole group, which is an essential component of purines, histidine and many cofactors, has been abiotically...

Tardigrades in Space Research - Past and Future
To survive exposure to space conditions, organisms should have certain characteristics including a high tolerance for freezing, radiation and...

The Influence of Mineral Matrices on the Thermal Behavior of Glycine
On the Hadean–Early Archean Earth, the first islands must have provided hot and dry environments for abiotically formed organic molecules. The heat...

Low Pressure Tolerance by Methanogens in an Aqueous Environment: Implications for Subsurface Life on Mars
The low pressure at the surface of Mars (average: 6 mbar) is one potentially biocidal factor that any extant life on the planet would need to endure....

Effects of Glycine, Water, Ammonia, and Ammonium Bicarbonate on the Oligomerization of Methionine
The abiotic oligomerization of amino acids may have created primordial, protein-like biological catalysts on the early Earth. Previous studies have...

Prebiotic Synthesis of Glycine from Ethanolamine in Simulated Archean Alkaline Hydrothermal Vents
Submarine hydrothermal vents are generally considered as the likely habitats for the origin and evolution of early life on Earth. In recent years, a...
