life : an organismic state characterized by capacity for metabolism, growth, reaction to stimuli, and reproduction — Webster

OneLook, Free Dictionary, Wiktionary, Urban Dictionary

Encyclopedia

Life is a characteristic distinguishing physical entities having biological processes, such as signaling and self-sustaining processes, from those that do not, either because such functions have ceased, or because they never had such functions and are classified as inanimate. Various forms of life exist, such as plants, animals, fungi, protists, archaea, and bacteria. The criteria can at times be ambiguous and may or may not define viruses, viroids, or potential artificial life as “living”. Biology is the primary science concerned with the study of life, although many other sciences are involved.

The definition of life is controversial. The current definition is that organisms maintain homeostasis, are composed of cells, undergo metabolism, can grow, adapt to their environment, respond to stimuli, and reproduce. However, many other biological definitions have been proposed, and there are some borderline cases of life, such as viruses. Properties common to all organisms include the need for certain core chemical elements to sustain biochemical functions. — Wikipedia

New Study Shows Viruses Can Have Immune Systems (Tufts Now)

Biosphere also known as the ecosphere, is the worldwide sum of all ecosystems. It can also be termed the zone of life on Earth, a closed system (apart from solar and cosmic radiation and heat from the interior of the Earth), and largely self-regulating. By the most general biophysiological definition, the biosphere is the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere, geosphere, cryosphere, hydrosphere, and atmosphere. — Wikipedia

Life sciences comprise the branches of science that involve the scientific study of life and organisms – such as microorganisms, plants, and animals including human beings. — Wikipedia

Life Sciences (Wolfram Alpha)

Biology is the natural science that studies life and living organisms, including their physical structure, chemical processes, molecular interactions, physiological mechanisms, development and evolution. Despite the complexity of the science, there are certain unifying concepts that consolidate it into a single, coherent field. Biology recognizes the cell as the basic unit of life, genes as the basic unit of heredity, and evolution as the engine that propels the creation and extinction of species. Living organisms are open systems that survive by transforming energy and decreasing their local entropy to maintain a stable and vital condition defined as homeostasis. — Wikipedia

    (University of Maryland) University of Maryland (UMD) was named one of ten winners worldwide for their stunning self-sustaining eco-restoration base, Ripple. As winners of the LAGI International Design Challenge, the team will build Ripple this summer on the Fly Ranch in the Nevada desert, part of the Burning Man Project. Ripple will be a flexible space to regenerate native plant diversity and ecological wisdom, paying equal homage to the land and the indigenous tribes who once lived there.

    A new study by Simon Fraser University historical ecologists finds that Indigenous-managed forests—cared for as "forest gardens"—contain more biologically and functionally diverse species than surrounding conifer-dominated forests and create important habitat for animals and pollinators. The findings are published today in Ecology and Society.

    Males may have shorter lifespans than females due to repetitive sections of the Y chromosome that create toxic effects as males get older. These new findings appear in a study by Doris Bachtrog of the University of California, Berkeley published April 22 in PLOS Genetics.
