The immortal DNA strand hypothesis was proposed in 1975 by John Cairns as a mechanism for adult stem cells to minimize mutations in their genomes. [1] This hypothesis proposes that instead of segregating their DNA during mitosis in a random manner, adult stem cells divide their DNA asymmetrically, and retain a distinct template set of DNA strands (parental strands) in each division.
Electron microscopy has accelerated research in materials science by quantifying properties and features from nanometer-resolution imaging with STEM, which is crucial in observing and confirming factors, such as thin film deposition, crystal growth, surface structure formation, and dislocation movement.
The STEM strand is under the Academic Track, which also includes other strands like ABM, HUMSS, and GAS. [57] [58] The purpose of the STEM strand is to educate students in the field of science, technology, engineering, and mathematics, in an interdisciplinary and applied approach, and to give students advanced knowledge and application in the ...
An academic discipline or field of study is known as a branch of knowledge. It is taught as an accredited part of higher education . A scholar's discipline is commonly defined and recognized by a university faculty.
An academic discipline or field of study is a branch of knowledge, taught and researched as part of higher education.A scholar's discipline is commonly defined by the university faculties and learned societies to which they belong and the academic journals in which they publish research.
Quantitative research is a research strategy that focuses on quantifying the collection and analysis of data. [1] It is formed from a deductive approach where emphasis is placed on the testing of theory, shaped by empiricist and positivist philosophies.
In marine ecology, "stress" and "adaptation" have been among the most common research topics, especially related to anthropogenic stress, such as global change and pollution. [155] Most of the studies in this area have been done in animals, although invertebrates have been underrepresented. [155]
It is an online publication and is published by the STEAM Education Research Association. The journal publishes articles from a range of topics in educational research and related disciplines. As the J-STEAM, it has an emphasis on the integration of STEAM topics, namely Science, Technology, Engineering, Art, and Mathematics. [15]
