Public broadcastingPublic broadcasting, sometimes public service broadcasting, is not subject to political interference or commercial influence. Public broadcasters receive funding from diverse sources including license fees, individual contributions, public financing and commercial financing. Common mediums include AM and FM radio, shortwave radio, television and the Internet. Public broadcasting may be nationally or locally operated, depending on the country and the station. In some countries a single organization runs public broadcasting.
Bisulfite sequencingBisulfite sequencing (also known as bisulphite sequencing) is the use of bisulfite treatment of DNA before routine sequencing to determine the pattern of methylation. DNA methylation was the first discovered epigenetic mark, and remains the most studied. In animals it predominantly involves the addition of a methyl group to the carbon-5 position of cytosine residues of the dinucleotide CpG, and is implicated in repression of transcriptional activity.
Public-access televisionPublic-access television (sometimes called community-access television) is traditionally a form of non-commercial mass media where the general public can create content television programming which is narrowcast through cable television specialty channels. Public-access television was created in the United States between 1969 and 1971 by the Federal Communications Commission (FCC), under Chairman Dean Burch, based on pioneering work and advocacy of George Stoney, Red Burns (Alternate Media Center), and Sidney Dean (City Club of NY).
Outer Space TreatyThe Outer Space Treaty, formally the Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies, is a multilateral treaty that forms the basis of international space law. Negotiated and drafted under the auspices of the United Nations, it was opened for signature in the United States, the United Kingdom, and the Soviet Union on 27 January 1967, entering into force on 10 October 1967.
Channel 4Channel 4 is a British free-to-air public broadcast television channel owned and operated by the state-owned Channel Four Television Corporation. It is publicly owned but, unlike the BBC, it receives no public funding and is instead funded entirely by its own commercial activities, including publicity. It began its transmission in 1982 and was established to provide a fourth television service in the United Kingdom. At the time, the only other channels were the licence-funded BBC One and BBC Two, and a single commercial broadcasting network ITV.
