Here's life imitating Star Trek:
A team of Canadian surgeons got a shock when the patient they were operating on began shedding dark greenish-black blood, the Lancet reports.
The man emulated Star Trek's Mr Spock - the Enterprise's science officer who supposedly had green Vulcan blood.
In this case, the unusual colour of the 42-year-old's blood was down to the migraine medication he was taking.
