New technologies and scientific imagination rearrange the boundary that we identify as the beginning and end of life. New techno-social constellations, such as the ever-increasing presence of digital avatars and genetic screenings, implore us to reconsider and transcend the existing definitions of life and death.

Upper Temperature Limit of Life
Science, 1963Samples of microorganisms from the hot springs of Yellowstone National Park have been collected and tested for the ability to utilize radioactive phosphorus. No evidence for growth was found above 73°C.

Homeotherms are substantially more capable of resisting cold than heat, if the normal rectal temperature is taken as the point of departure. With the possible exception of man, the number and effectiveness of the mechanisms protecting against loss of heat are also far greater.

Of Ageism, Suicide, and Limiting Life
Journal of Gerontological Social Work, 1995Increased longevity, life-extending medical technol- ogy, and growing health-care costs have given rise to much discus- sion of the meaning of life in old age and to suggestions that limits be set on the length of life: by suicide or by limiting medical treat- ment. It is argued that, while recommendations that treatment be limited or suicide be viewed

What is life? What is water? What is sound? This book investigates how contemporary scientists—biologists, oceanographers, and audio engineers—are redefining these crucial concepts. Life, water, and sound are phenomena at once empirical and abstract, material and formal, scientific and social. In the age of synthetic biology, rising sea levels, and new

Microbial Extremophiles at the Limits of Life
Critical Reviews in Microbiology, 2007Prokaryotic extremophiles were the first representatives of life on Earth and they are responsible for the genesis of geological structures during the evolution and creation of all currently known ecosystems. Flexibility of the genome probably allowed life to adapt to a wide spectrum of extreme environments.

On the decomposition of life expectancy and limits to life
Population Studies, 2015Life expectancy is a measure of how long people are expected to live and is widely used as a measure of human development. Variations in the measure reflect not only the process of ageing but also the impacts of such events as epidemics, wars, and economic recessions.

The Life Course of Activity Limitations:
Journal of Aging and Health, 2004Objective: To strengthen the foundations for the use of survey-based measures of functional limitations and to explore associations between limitations in a variety of activities across the adult life course. Method: Five panels of data from the young and mature women’s cohorts of the National Longitudinal Surveys are used to (a) examine patterns of ...

The field of stability of life extends beyond the limits of the biosphere, and the independent variables which determine the stability (temperature, chemical composition, etc.) attain values well beyond the characteristic biospheric extremes of these quantities.

Limits of Life, Limits of the Body
In the past, the view according to which the limits of human lives can be questioned had often been advocated by people on the basis of religious dogmas concerning the soul's immortality; today, curiously, many endorse the same view on the basis of a scientific conception of Life which posits that Life can be abstracted away from any particular medium.openaire +2 more sources
