A plan to sequence Salvador Dali's DNA in a bid to "analyze the genetic basis of creativity" has been rejected by the foundation set up to manage his legacy.

The DNA is not the problem - 10 years ago half of the Spanish painter's right leg as well as three teeth, four fingernails and a lock of his hair were exhumed for a paternity test and the samples are still in a lab near Madrid.

Geneticist Antonio Alonso, who carried out that test proving the paternity claim was false, said the experiment would justify the "outrageous" desecration of Dali's grave.

He told El Pais newspaper: "Since they had the audacity to cut off his legs and ship them in a box, we might as well take advantage of the situation to derive some additional value."

But a spokesperson for the Gala-Salvador Dalí Foundation said it "does not intend to promote or support an undertaking of this kind" which "raises particularly sensitive ethical, legal, and scientific questions".

A show examining Dali's fascination with the theories of psychoanalyst Sigmund Freud is at the Thyssen museum in Madrid until January 24.

The amount of money this year's Dark Mofo festival says it generated for the local economy in Tasmania. The Australian festival, held annually near Hobart by David Walsh's Museum of Old and New Art (MONA), returns next year between June 9-22.

Visitors to Yoshitomo Nara's New York show that opened last night will notice his increasing use of contrasting colors but the change in style is nothing to do with his artistic approach - his sight is getting worse.

The show features around 80 paintings and drawings including works from this year as well as some dating back to the 1980s and the newer work features less crisp lines.

He told The New York Times he has been diagnosed with glaucoma and the eye condition means he can not paint fine details and now uses wider brushes.

The 66-year-old Japanese painter told the newspaper he is also painting less, adding: “If I were a child, I could draw a lot more."

The show is at the David Zwirner gallery in Chelsea until December 12.

Kehinde Wiley said his offer to buy back one of his paintings taken down from a US embassy after being dubbed "aesthetically terrifying" has been ignored.

The painting, Young Artists After Siamesas 1960, was removed from the building in the Dominican Republic.

Ambassador Leah Campos posted a video of its removal, soundtracked by the song "We're Not Gonna Take It' by heavy metal band Twisted Sister, and said it represented "turning away from globalist and woke ideologies and instead embracing American patriotism".

Wylie told The New York Times there had been "no response" to his offer but he was not "terribly surprised".

The painter also said he did not intend to "incorporate" recent events in his personal life, which include accusations of sexual misconduct which he denies, into his work because he does not "want to see my practice affected by that."

He told the newspaper reported falls in the prices paid for his work were nothing to do with the allegations, instead putting it down to a lack of demand for the wall-size paintings he makes.
