Stem-cell lines: Two of the most popular lines of human embryonic stem cells, H9 and H7, are now eligible for use by US-government-funded researchers. The lines were approved under the George W. Bush administration, but have spent months waiting for the green light (see Nature 464,967; 2010) under a liberalized policy announced by President Barack Obama in March 2009. The National Institutes of Health in Bethesda, Maryland, added them, along with 11 other newcomers, to its registry of federally fundable stem-cell lines on 27 April.rnHIV ban lifted: The State Council of China has announced that it will no longer bar people with HIV from entering the country. In a statement on 27 April, it said that the ban had a very limited effect in controlling diseases, and was inconvenient for those visiting major events. China joins South Korea and the United States in repealing HIV entry bans this year. The United Nations lists 51 countries, territories and areas with restrictions on the travel of HIV-positive individuals.
