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.
A senior US Republican has urged President Donald Trump to temporarily reopen parts of the government shut down for more than three weeks.
Senator Lindsey Graham, who is close to Mr Trump, said a limited re-opening of a few weeks would allow talks to resume between Republicans and Democrats.
The partial government shutdown has now become the longest in US history.
