The domain name edu is a sponsored top-level domain (sTLD) in the Domain Name System of the Internet. Since 2001, new registrants to the domain have been required to be United States-affiliated institutions of higher education, though before then non-U.S.-affiliated—and even non-educational institutions—registered, with some retaining their registrations to the present.
The .edu domain was implemented in April 1985 as a generic top-level domains. Six universities were the initial registrants that month.
Until 2001, Network Solutions served as registrar for the .edu domain under an arrangement with the U.S. Department of Commerce. Domain registration was done at no cost to educational institutions. In 2001, the Commerce Department entered into a five-year agreement with Educause making that organization the registrar for the .edu domain. The agreement with Educause was extended for an additional five-year period in 2006; at that time Educause was authorized to begin charging a yearly administrative fee to registrants.

5-Ethynyl-2´-deoxyuridine (EdU) is a thymidine analogue which is incorporated into the DNA of dividing cells and is used to assay DNA synthesis in cell culture. At high doses it can be cytotoxic.
EdU is detected with a fluorescent azide which forms a covalent bond using click chemistry. Unlike the commonly used bromodeoxyuridine, EdU detection requires no heat or acid treatment.
