The power of this victory rests on the fact that it’s about public participation; a critical step in getting the landfills shut down. It was a personal mission as both landfills are very close to houses, and the area has high cancer rates – this is what motivated us to start the campaign.

I literally said to them - all of our faces were on the - in the boxes on Zoom. And I welled up. And I said, oh my God, this is my dream. This is what I want - I've wanted to see my whole life of working at Ariel and all the things we've built, and making sure we all have a shot at this - narrowing this wealth gap, and putting our stamp on the industry and society.

That’s easy, my trainees. In my field, receptor biology, the field is dominated by people that I trained. Kobilka is one example. I would say I have, for years — in all due modesty — I led the field. I passed that mantle to Kobilka. He has the newest technologies and this and that. But he’s just the limit case. There are dozens and dozens of people who trained with me that, if you go to any meeting on receptor biology and you look at the program, I don’t know, 30 to 40 percent of all the speakers will have either trained with me or trained with people who trained with me. They’re in the lineage. So that’s what I’m most proud of.

Very happy, very proud, apart from the loss of many lives, which can never be corrected, or we can’t do much about it. It’s probably the most expensive part of the struggle. But to have won the war and won the peace for ourselves, because if you look at those years of the war, of the genocide, and they are brought to an end, and then we started building and rebuilding and a sense of reconciliation, a sense of allowing Rwandans to live together as a nation. And now a proud people of Rwanda, and socially made progress politically, significant progress, economically the same. I think we could not have asked for more.

Instant information about everything and everyone often allows an individual opinion to compete with consensus and paranoia with evidence. It is a time when one blunt honest statement can finish a life-long political career, and one opinionated journalist can bully a government or a royal family. Science is not immune from such pressures. For example, how many Nobel prize-winning experiments – you think – would have been stopped, if ethics or health-and-safety regulations at that time were as zealous as they are today? I can think of more than a few.
