– Gogo Goes to Brazil: Never one to leave a bubbling art market untapped, Larry Gagosian will stage a major sculpture exhibition in a warehouse in Rio de Janeiro as part of the ArtRio fair. The exhibition follows his 2011 Paris show "Brazil: Reinvention of the Modern." The gallery will also have a separate booth at ArtRio, which runs September 12 to 16. Both venues will showcase a broad group of gallery artists, from Yayoi Kusama to Robert Rauschenberg. Could the mega-dealer be gunning to add a 13th gallery to his empire? [NYT, Press Release]

– Ai Weiwei's Appeal Thrown Out: Chinese courts have rejected artist and activist Ai Weiwei's appeal of a $2-million tax fine that the company producing his work, Beijing Fake Cultural Development Ltd., was hit with following his 81-day detainment last year. "Today's verdict shows that this country, more than 60 years after its founding still has no basic legal process," Ai said, "still has no respect for the truth, still will never give taxpayers and citizens an ability to justify themselves." Meanwhile, China says he remains under investigation on suspicion of illegal exchange of foreign currency and pornography. [Guardian]

– Wax On, Wax On: In early 2013, Washington, D.C.'s Phillips Collection will put a beeswax room installation by Wolfgang Laib on permanent display in a converted storage room, despite the small private museum's ever-present space constraints. "It is painful, the paucity of real estate for our collection,” says director Dorothy Kosinski. "The last thing I want to do is pin down our small space with something permanent and site-specific." For Laib, however, she will. [WaPo]
