Greetings from Vancouver, where I am attending ICBIC15 – the international conference on bio-inorganic chemistry. As the name suggests, this is the 15th instalment of this series of conferences…or is it? There have been quite a few mentions of a mysterious ‘ICBIC zero’, which happened 35 years ago, also here at the University of British Columbia in Vancouver. Chris Orvig, the chair, showed us the programme from that meeting during his welcome address – as organizer, he was interested to see that there were no times for any of the talks, just ‘morning’ or ‘afternoon’! The only speaker at that conference who is also speaking this year is (no prizes for guessing) Harry Gray, who is quite a godfather of this field.
