IN: Ai Weiwei (Chinese: Ai Wei Wei ; pinyin: Ai Weiwei,  English pronunciation ; born 28 August 1957 in Beijing) is a Chinese contemporary artist and activist. His father's (Ai Qing) original surname was written Jiang (Jiang ). Ai collaborated with Swiss architects Herzog & de Meuron as the artistic consultant on the Beijing National Stadium for the 2008 Olympics.

On 22 June 2011, the Chinese authorities released Ai from jail after almost three months' detention on charges of tax evasion. Beijing Fa Ke Cultural Development Ltd. (Chinese: Bei Jing Fa Ke Wen Hua Gong Si ), a company Ai controlled, had allegedly evaded taxes and intentionally destroyed accounting documents. State media also reports that Ai was granted bail on account of Ai's "good attitude in confessing his crimes", willingness to pay back taxes, and his chronic illnesses. According to the Chinese Foreign Ministry, he is prohibited from leaving Beijing without permission for one year. Ai's supporters widely viewed his detention as retaliation for his vocal criticism of the government. On 23 June 2011, professor Wang Yujin of China University of Political Science and Law stated that the release of Ai on bail shows that the Chinese government could not find any solid evidence of Ai's alleged "economic crime". On 24 June 2011, Ai told a Radio Free Asia reporter that he was thankful for the support of the Hong Kong public, and praised Hong Kong's conscious society. Ai also mentioned that his detention by the Chinese regime was hellish (Chinese: Jiu Si Yi Sheng ), and stressed that he is forbidden to say too much to reporters.  After his release, his sister gave some details about his detention condition to the press, explaining that he was subjected to a kind of psychological torture: he was detained in a tiny room with constant light, and two guards were set very close to him at all times, and watched him constantly. In November, Chinese authorities were again investigating Ai and his associates, this time under the charge of spreading pornography. Lu was subsequently questioned by police, and released after several hours though the exact charges remain unclear. In January 2012, in its International Review issue Art in America magazine featured an interview with Ai Weiwei at his home in China. J.J. Camille (the pen name of a Chinese-born writer living in New York), "neither a journalist nor an activist but simply an art lover who wanted to talk to him" had travelled to Beijing the previous September to conduct the interview and to write about his visit to "China's most famous dissident artist" for the magazine.  On 21 June 2012, Ai's bail was lifted. Although he is allowed to leave Beijing, the police informed him that he is still prohibited from traveling to other countries because he is "suspected of other crimes," including pornography, bigamy and illicit exchange of foreign currency. Until 2015, he remained under heavy surveillance and restrictions of movement, but continues to criticize through his work. In July 2015, he was given a passport and may travel abroad.

IN: Sanjay Gupta ( SAHN-jay GOOP-t@; born October 23, 1969) is an American neurosurgeon and medical reporter. He serves as associate chief of the neurosurgery service at Grady Memorial Hospital in Atlanta, Georgia, and as assistant professor of neurosurgery at the Emory University School of Medicine. A media personality on health-related issues, he is best known as CNN's multiple Emmy Award-winning chief medical correspondent, hosting the network's weekend health program Sanjay Gupta, M.D., and making frequent appearances on their American Morning, Larry King Live and Anderson Cooper 360deg programs. His reports from Charity Hospital, New Orleans, Louisiana, in the wake of Hurricane Katrina led to him winning a 2006 Emmy Award for Outstanding Feature Story in a Regularly Scheduled Newscast.

On January 6, 2009, CNN announced that Gupta had been considered for the position of Surgeon General by President Barack Obama.  Some doctors said that his communication skills and high profile would allow him to highlight medical issues and prioritize medical reform. However, others raised concerns about potential conflicts of interest with drug companies who have sponsored his broadcasts and his lack of skepticism in weighing the costs and benefits of medical treatments.  Representative John Conyers, Jr. (D-MI), wrote a letter opposing Gupta's nomination. Conyers supports a single-payer health care system, the sort that Conyers' filmmaker friend Michael Moore advocated in his documentary Sicko; Gupta has criticized Moore and the film.  Others, such as liberal commentator Jane Hamsher, defended the appointment, noting that Gupta's responsibilities as a surgeon general would be not that different from those of his CNN position, and that Gupta's media presence would make him ideal for the position. From the medical community, Donna Wright, of Creative Health Care Management, a regular commentator on medicine and politics, also defended the appointment on the grounds of his media presence, combined with his medical qualifications, which she viewed as an ideal combination for the post of surgeon general. Likewise, Fred Sanfilippo, executive vice president for health affairs at Emory University, supported Gupta's nomination by issuing a press release saying: "He has the character, training, intelligence and communications skills needed to help the United States improve its health and health care delivery systems in the next Administration." The American Council on Exercise, listed by PR Newswire as "America's leading authority on fitness and one of the largest fitness certification, education and training organizations in the world", endorsed the nomination of Gupta "because of his passion for inspiring Americans to lead healthier, more active lives". The ACE sent a letter of support to senator Edward M. Kennedy. Former surgeon general Joycelyn Elders also supported Gupta's nomination, saying: "He has enough well-trained, well-qualified public health people to teach him the things he needs to do the job." In March 2009 Gupta withdrew his name from consideration for the post, citing his family and his career.
