Organisms are highly organized structures that consist of one or more cells. Even very simple, single-celled organisms are remarkably complex. Inside each cell, atoms make up molecules. These in turn make up cell components or organelles. Multicellular organisms, which may consist of millions of i...
Synthetic biology has reached the same inflection point achieved by computer science in the 1950's The foundational pieces emerging, in the form of standardized DNA parts, packaged for combinatoric assembly using standards such as BioBricks. But: Creating new DNA parts is tedious and time-consumin...

Model organisms are widely used in research as accessible and convenient systems to study a particular area or question in biology. Traditionally only a handful of organisms have been widely studied, but modern research tools are enabling researchers to
heterotrophic protists, which actively seek and ingest their food (either food particles or other organisms) Binomial Nomenclature How we classify organisms If to organisms are in the same Class, then they also must be in the same...
1533), “ecosystems are not living organisms”, since “they do not behave like organisms and do not have properties of organisms such as health”. For this author, this means that health at the ecosystem level is mostly a metaphor, that is, a mere heuristic tool that human beings create...
Humus ((h)yo͞oməs) is a part of soil that contains recently broken down organic material, such as plants, dead organisms, manure etc. Essentially, it is the part of the soil which contains all the recycled nutrients from a system that can be used again. It generally is a lot ...

Redox signaling acts as a critical mediator in the dynamic interactions between organisms and their external environment, profoundly influencing both the onset and progression of various diseases. Under physiological conditions, oxidative free radicals g
