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

(Children's Hospital of Philadelphia) Researchers from Children's Hospital of Philadelphia (CHOP) have found that NTRK fusions are more common in pediatric tumors and also involve a wider range of tumors than adult cancers, information that could help prioritize screening for NTRK fusions in pediatric cancer patients who might benefit from treatment with TRK inhibitors.

(Technische Universität Dresden) Scientists from the Faculty of Biology (TU Dresden) and the Kurt Schwabe Institut für Mess- und Sensortechnik Meinsberg e.V. want to develop an innovativel biological yeast cell-based sensor for the detection of pharmaceutical residues in soil and wastewater in their joint project "Implementation of a yeast pheromone-based signal amplifier system for environmental monitoring of pharmaceutical residues in water" (ISAr). The project is funded by the Free State […]

(UK Research and Innovation) A new national research project to study the effects of emerging mutations in SARS-CoV-2 will be launched with £2.5 million of funding from UK Research and Innovation. The 'G2P-UK' National Virology Consortium will study how mutations in the virus affect key outcomes such as how transmissible it is, the severity of COVID-19 it causes, and the effectiveness of vaccines and treatments.

(Oregon Health & Science University) Scientists have uncovered new clues implicating a type of herpes virus as the cause of a central nervous system disease in monkeys that's similar to multiple sclerosis in people. By linking two specific T cells to the loss of myelin, scientists say the new study opens the possibility of developing an antiviral therapy that could be especially useful for newly diagnosed cases of multiple sclerosis.

Scientists studying the body's natural defenses against bacterial infection have identified a nutrient—taurine—that helps the gut recall prior infections and kill invading bacteria, such as Klebsiella pneumoniae (Kpn). The finding, published in the journal Cell by scientists from five institutes of the National Institutes of Health, could aid efforts seeking alternatives to antibiotics.
