Open Science's website is made by Diplococcus, a nonprofit organization with the objective of spreading knowledge from everyone to everyone for free.
Open science is the movement to make scientific research (including publications, data, physical samples, and software) and its dissemination accessible to all levels of society, amateur or professional. Open science is transparent and accessible knowledge that is shared and developed through collaborative networks.
It encompasses practices such as publishing open research, campaigning for open access, encouraging scientists to practice open-notebook science, broader dissemination and engagement in science and generally making it easier to publish, access and communicate scientific knowledge.
