Frontiers

Frontiers is the plural form of frontier and is used in a variety of contexts to denote the outer limits of physical space, knowledge, or experience, as well as borderlands between regions. In common usage, frontiers describe areas at the edge of exploration or inquiry where current understanding is incomplete or evolving.

In science and academia, frontiers refer to domains at the cutting edge of research, such as the frontiers of physics, biology, or climate science. The term conveys both the challenge of the unknown and the opportunity for discovery that motivates investigative work.

Frontiers also refers to a contemporary scholarly publisher. Frontiers Media S.A., commonly known simply as Frontiers, is a Swiss open-access publishing company established in 2007. It publishes a broad portfolio of peer-reviewed journals across disciplines, including Frontiers in Neuroscience, Frontiers in Psychology, and Frontiers in Earth Science. The publisher operates on an open-access model and assigns article processing charges to authors, aiming to provide wide accessibility and rapid dissemination of research.

In culture, Frontiers is the title of a 1983 studio album by the American rock band Journey. The work is regarded as part of the band’s mature period and includes several commercially successful tracks.

Geographically and historically, frontiers have described borderlands or contested regions where cultures, empires, or ideas meet and interact. The concept remains central to discussions of exploration, hypothesis testing, and interdisciplinary collaboration.
