Muscle aches are also known as muscle pain, myalgia, or simply pain in the muscles. Muscle aches are extremely common. Almost everybody has likely experienced discomfort in his or her muscles at some point. Because almost every part of the body has muscle tissue, this type of pain can be felt practically anywhere in the body.
Common causes include: muscle tension in one or more areas of the body
Overusing the muscle during physical activity
Injuring the muscle while engaging in physically demanding work or exercise (muscle sprains and strains are both injuries that can cause muscle aches and pain).
Open access to the scientific literature means the removal of barriers (including price barriers) from accessing scholarly work. There are two parallel roads towards open access: Open Access articles and self-archiving. Open Access articles are immediately, freely available on their Web site, a model mostly funded by charges paid by the author (usually through a research grant). The alternative for a researcher is self-archiving (i.e., to publish in a traditional journal, where only subscribers have immediate access, but to make the article available on their personal and/or institutional Web sites (including so-called repositories or archives), which is a practice allowed by many scholarly journals.
Open Access rises practical and policy questions for scholars, publishers, funders, and policymakers alike, including what the return on investment is when paying an article processing fee to publish in an Open Access articles, or whether investments into institutional repositories should be made and whether self-archiving should be made mandatory, as contemplated by some funders.
