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

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

Encyclopædia Britannica
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 (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

- DeepSqueak tool identifies marine mammal callson May 23, 2022 at 4:33 pm
Lurking beneath the ocean's surface, marine mammals use sound for navigation, prey detection, and a wide range of natural behaviors. Passive acoustic data from underwater environments can provide valuable information on these animals, such as their presence or absence within an area, their density and abundance, and their vocal response to anthropogenic noise sources.
- Turning X chromosome 'off and on again' critical...on May 23, 2022 at 4:31 pm
Researchers at the Centre for Genomic Regulation (CRG) in Barcelona have identified a potential new diagnostic marker that predicts the successful and efficient development of mammalian egg cells. The findings could pave the way for generating artificial oocytes in the laboratory, helping researchers study the causes and treatments of infertility disorders and test the impact of drugs and chemicals on women's reproduction. The research is published in The EMBO Journal.

Salamanders that live their entire lives in the crowns of the world's tallest trees, California's coast redwoods, have evolved a behavior well-adapted to the dangers of falling from high places: the ability to parachute, glide and maneuver in mid-air.
