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.

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

Valuing life detection missions [PDF]
Astrobiology, 2018 Recent discoveries imply that Early Mars was habitable for life-as-we-know-it; that Enceladus might be habitable; and that many stars have Earth-sized exoplanets whose insolation favors surface liquid water. These exciting discoveries make it more likely

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

Returning Samples From Enceladus for Life Detection [PDF]
Frontiers in Astronomy and Space Sciences, 2020 Evidence suggests that Saturn's icy moon Enceladus has a subsurface ocean that sources plumes of water vapor and ice vented to space from its south pole.

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 ...
