Reporter gene. A diagram of a how a reporter gene is used to study a regulatory sequence. In molecular biology, a reporter gene (often simply reporter) is a gene that researchers attach to a regulatory sequence of another gene of interest in bacteria, cell culture, animals or plants. Such genes are called reporters because the characteristics ...
Strong's original Inventory had 10 occupational scales. The original Inventory was created with men in mind, so in 1933 Strong came out with a women's form of the Strong Vocational Blank.

In philosophy of science, strong inference is a model of scientific inquiry that emphasizes the need for alternative hypotheses, rather than a single hypothesis to avoid confirmation bias . The term "strong inference" was coined by John R. Platt, [1] a biophysicist at the University of Chicago. Platt notes that some fields, such as molecular ...
Biomimetics or biomimicry is the emulation of the models, systems, and elements of nature for the purpose of solving complex human problems. [2] [3] [4] The terms "biomimetics" and "biomimicry" are derived from Ancient Greek: βίος ( bios ), life, and μίμησις ( mīmēsis ), imitation, from μιμεῖσθαι ( mīmeisthai ), to ...

A philia is the love or obsession with a particular thing or subject.
