It should also be added to the list that the Express recently published a story headlined "NO evidence of impact to UK Science from Brexit, says Nobel Laureate", or words to that effect. Except, he didn't say that, and was referring specifically to Horizon 2020 funding deals not being affected, whilst also warning of effects that have happened (many due to perceived risks, rather than actual ones, to be fair) whereby British Scientists have been excluded from some EU-based projects and consortia, and other planned collaborations have been postponed; and was concerned about the effect of the Referendum vote on the perception of the UK when it comes to Science. All of this is to say that a) there are legitimate fears of damage to the UK's reputation, even though of course these fears may not be realised, and so b) it was absolutely *not* the point of Venki Ramakrishnan's speech to say that Brexit had no effect. The Daily Express simply lied in reporting his comments that way.
