The Ladder of Life Detection [PDF]
Astrobiology, 2018 We describe the history and features of the Ladder of Life Detection, a tool intended to guide the design of investigations to detect microbial life within the practical constraints of robotic space missions. To build the Ladder, we have drawn from lessons learned from previous attempts at detecting life and derived criteria for a measurement (or suite

Evaluating Biosignatures for Life Detection. [PDF]
Astrobiology, 2020 Conceptual frameworks are developed for evaluating the ability of different biosignatures to provide evidence for the presence of life in planned missions or observational studies. The focus is on intrinsic characteristics of biosignatures in space environments rather than on their detection, which depends on technology. Evaluation procedures are drawn

Life Detection From Biological Motion. [PDF]
Curr Dir Psychol Sci, 2023 Life motion, the active movements of people and other animals, contains a wealth of information that is potentially accessible to the visual system of an observer. Biological-motion point-light displays have been widely used to study both the information contained in life motion stimuli and the visual mechanisms that make use of it.

Automatic Life Detection Based on Efficient Features of Ground-Penetrating Rescue Radar Signals [PDF]
Sensors, 2023 Good feature engineering is a prerequisite for accurate classification, especially in challenging scenarios such as detecting the breathing of living persons trapped under building rubble using bioradar.

The future of spectroscopic life detection on exoplanets. [PDF]
Proc Natl Acad Sci U S A, 2014 The discovery and characterization of exoplanets have the potential to offer the world one of the most impactful findings ever in the history of astronomy—the identification of life beyond Earth. Life can be inferred by the presence of atmospheric biosignature gases—gases produced by life that can accumulate to detectable levels in an exoplanet ...

Biota and Biomolecules in Extreme Environments on Earth: Implications for Life Detection on Mars [PDF]
Life, 2014 The three main requirements for life as we know it are the presence of organic compounds, liquid water, and free energy. Several groups of organic compounds (e.g., amino acids, nucleobases, lipids) occur in all life forms on Earth and are used as ...
