Lipids constitute resistant biomarkers that have been proposed as pacemakers in the search for possible microbial life-forms in Mars’ past.
Introduction – Cryo-hypersaline brines combine sub-zero temperatures with near-saturated salinity, creating one of Earth’s most extreme habitats. Antarctic Deep Lake provides a natural model for studying how proteins remain stable […]
Editor’s note: If you are on a long term mission or on an away team on another world, you might want your tricorder to be able to do some quick […]
Experimentally modeling the habitability of extreme ocean world conditions, such as those on Jupiter’s moon: Europa, would benefit from integrated microbe-virus model studies to provide both a microbial model and […]
Editor’s note: If we aspire to mount expeditions to new worlds and then embrace the task of characterizing and quantifying whatever life forms we find, the ability to map and […]
Present-day Venus, similar to Earth in terms of relative radius, acceleration of gravity and mean density, is characterised by a very strong greenhouse effect and full cloud cover.
Mycorrhizal fungi form underground networks that sustain plant life and help regulate Earth’s climate by drawing carbon into soils.
Micro organisms from our planet could survive on celestial bodies where water is present, such as Mars. That is the conclusion of PhD candidate Tommaso Zaccaria after experiments with simulated […]
The evolutionary origin of red algae‐derived complex plastids remains obscure. Cryptophyta, one of four eukaryotic lineages harboring these plastids, still contains nucleomorphs, which are highly reduced remnants of red algal […]
Background/Objectives: tRNAs, tRNAomes, aminoacyl-tRNA synthetases (AARSs), the first proteins, ribosomes and the genetic code coevolved. We utilize sequence data to reconstruct key steps in establishing the first code on Earth.
