Nobel Prize-winning American scientist James Watson has been stripped of his honorary titles after repeating comments about race and intelligence.
In a TV programme, the pioneer in DNA studies made a reference to a view that genes cause a difference on average between blacks and whites on IQ tests. Cold Spring Harbor Laboratory said the 90-year-old scientist's remarks were "unsubstantiated and reckless". Dr Watson had made similar claims in 2007 - and subsequently apologised. He shared the Nobel in 1962 with Maurice Wilkins and Francis Crick for their 1953 discovery of the DNA's double helix structure.
