Application of chemotactic behavior for life detection
Frontiers in Astronomy and Space SciencesOne excellent biosignature for the present detection of microbial life on Earth is motility, leading to its growing interest within the astrobiological community as an observable attribute that, if detected during future in situ space missions, could ...

Recent Progress in Chirality Research Using Circularly Polarized Light [PDF]
Photochemistry: UV/VIS Spectroscopy, Photochemical Reactions and
Photosynthesis: Nova Science Publishers (2011), pp.291-308, 2010 (abridged) We review recent studies of chirality using circularly polarized light, along with the birth and evolution of life and planetary systems. Terrestrial life consists almost exclusively of one enantiomer, left-handed amino acids. This characteristic feature is called homochirality, whose origin is still unknown.

Wearable Affective Life-Log System for Understanding Emotion Dynamics in Daily Life [PDF]
arXiv, 2019 Past research on recognizing human affect has made use of a variety of physiological sensors in many ways. Nonetheless, how affective dynamics are influenced in the context of human daily life has not yet been explored. In this work, we present a wearable affective life-log system (ALIS), that is robust as well as easy to use in daily life to detect ...

Exoplanet Biosignatures: Future Directions [PDF]
, 2017 Exoplanet science promises a continued rapid accumulation of new observations in the near future, energizing a drive to understand and interpret the forthcoming wealth of data to identify signs of life beyond our Solar System. The large statistics of exoplanet samples, combined with the ambiguity of our understanding of universal properties of life and

Strategies for the search of life in the universe [PDF]
arXiv, 1996 The discovery of an increasing number of Jupiter-like planets in orbit around other stars (or extra-solar planets) is a promising first step toward the search for Life in the Universe. We review all aspects of the question: - definition of Life - definition and characterization of the `habitable zone' around a star - overview of detection methods of ...

Evaluation of a Sensor System for Detecting Humans Trapped under Rubble: A Pilot Study
Sensors, 2018 Rapid localization of injured survivors by rescue teams to prevent death is a major issue. In this paper, a sensor system for human rescue including three different types of sensors, a CO2 sensor, a thermal camera, and a microphone, is proposed.

Imaging technologies and strategies for detection of extant extraterrestrial microorganisms
Advances in Physics: X, 2018 There is no reductionist definition of life, so the way organisms look, behave, and move is the most definitive way to identify extraterrestrial life.
