Abstract

fetched live from OpenAlex

All life on Earth represents a common genetic and biochemical system descendent from a common ancestor. The other worlds in our solar system that are the most promising targets in the search for life are Mars, Europa (a moon of Jupiter), and Enceladus (a moon of Saturn). Perchlorates are also metabolically active. It is known that microorganisms on Earth are capable of using perchlorates as electron acceptors, allowing anaerobic microbial respiration to occur where perchlorate replaces oxygen as the terminal electron acceptor. Studies of the microbes in the ground ice below dry permafrost in University Valley show that there is an adapted microbial community, and RNA data show that there is microbial activity. The availability of liquid water within the Martian subsurface (permafrost or regolith) would be concentrated into eutectic brines. As such, the microorganisms that could survive and potentially remain viable under such growth conditions would most likely be halophilic cryophiles. While the northern plains represent the most likely site of recent life due to the melting of near-surface ice, the southern highlands represent the best location to find long-frozen remains of ancient life on Mars. In the outer solar system there are two worlds that potentially have liquid water under layers of ice: Europa and Enceladus. In addition to Mars, Europa, and Enceladus, there are other worlds of interest to astrobiology-and they are also icy worlds.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
