Biological ablation: Used to remove a biological structure or functionality: Genetics, Physiology: Calcium imaging: Used to optically measure the status of calcium ions (Ca 2+) in an isolated cell, tissue or medium: Physiology: Cell isolation: Process of separating individual living cells from a solid block of tissue or cell suspension: Cell ...
The biological study of how the origin of life produced reproducing organisms from non-reproducing elements is called abiogenesis. Whether or not there were several independent abiogenetic events, biologists believe that the last universal ancestor to all present life on Earth lived about 3.5 billion years ago .
The word is derived from the Greek φαίνω (phainō), "to show, to bring to light, make to appear" [6] + λόγος (), amongst others "study, discourse, reasoning" [7] and indicates that phenology has been principally concerned with the dates of first occurrence of biological events in their annual cycle.

Dolly was formed by taking a cell from the udder of her 6-year-old biological mother. [30] Dolly's embryo was created by taking the cell and inserting it into a sheep ovum. It took 435 attempts before an embryo was successful. [31] The embryo was then placed inside a female sheep that went through a normal pregnancy. [32]

Different models of 3D printing tissue and organs. Three dimensional (3D) bioprinting is the use of 3D printing–like techniques to combine cells, growth factors, bio-inks, and biomaterials to fabricate functional structures that were traditionally used for tissue engineering applications but in recent times have seen increased interest in other applications such as biosensing, and ...
These three versions, and their corresponding newly developed laboratory exercises, were piloted at high schools around the United States during the 1960–61 school year. The curriculum materials were then revised during the summer of 1961 based on feedback from teachers, students, and professional biologists, and tested again during 1961–62.
