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

(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.
- Fighting harmful bacteria with nanoparticleson April 22, 2021 at 4:00 am
(Swiss Federal Laboratories for Materials Science and Technology (EMPA)) Multi-resistant pathogens are a serious and increasing problem in today's medicine. Where antibiotics are ineffective, these bacteria can cause life-threatening infections. Researchers at Empa and ETH Zurich are currently developing nanoparticles that can be used to detect and kill multi-resistant pathogens that hide inside our body cells. The team published the study in the current issue of the journal Nanoscale.

(National University of Science and Technology MISIS) NUST MISIS scientists together with Indian colleagues from Jain University and Sri Dharmasthala Manjunatheshwara College presented innovative membranes for the complete removal of heavy metals from industrial wastewater. The special nanostructure of zinc-modified aluminum oxide made it possible to remove arsenic and lead from water with an efficiency of 87% and 98%, respectively. The results of the work were published in the Chemosphere […]

(Cactus Communications) Genome wide analyses have revealed that MSEI, a gene linked with anemia is also associated with insomnia. The correlation between the two conditions, however, remains largely unexplored in adults. Thus, in a cross-sectional study, researchers assessed the relation between anemia and insomnia in a large Chinese cohort. Their findings, published in Chinese Medical Journal, suggest that anemia increases the risk of insomnia. Further studies can help elucidate the underlying […]

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.

The international consortium of scientists and conservationists working towards preventing the extinction of the northern white rhino through advanced assisted reproduction technologies is pleased to announce that in March and April 2021, four additional northern white rhino embryos were produced.
- XYZeq: A better map of cell diversityon April 22, 2021 at 3:05 pm
Not all cancer cells within a tumor are created equal; nor do all immune cells (or all liver or brain cells) in your body have the same job. Much of their function depends on their location. Now, researchers at Gladstone Institutes, UC San Francisco (UCSF), and UC Berkeley have developed a more efficient method than ever before to simultaneously map the specialized diversity and spatial location of individual cells within a tissue or a tumor.
