It was amazing, but you missed it: the legendary gig, the party, the good, sexy part of the Sixties, the Salon des Refusés, fluxus, punk, the first performance of Stravinsky and the Ballet Russes' The Rite of Spring, the first exhibition of Duchamp's fountain. Also, other things you might have missed – the chance to say goodbye, to apologise, to have a love affair, to be there on that night that everybody still laughs about now. It's in this gulf of missed or denied opportunities that Ryan Gander pitches his latest, elusive, project produced by Artangel.

Philip Morris seeks to force university to hand over confidential health research into teenage smokers

It is disquieting, to put it mildly, that Philip Morris – the very embodiment of Big Tobacco – has applied to see a university department's data on smoking habits. The research programme, which is trying to identify what makes smoking attractive to young people, is funded in part by the Department of Health and cancer charities. But the relevance of the same information to tobacco companies' marketing departments can hardly be a mystery. With the vast majority of adult smokers becoming hooked in their teens, this is where the battle has to be fought and won.

There are striking parallels between the attempt by the tobacco industry to seek academic research data held by Stirling University using the Freedom of Information law and the campaign to gain access to research data held by the Climatic Research Unit at the University of East Anglia.

Dear Virginia, I've had a relationship with a man for a year. It's been on-off, and from the start he said he really wanted a younger woman who could give him children. He's even confided with me about suitable candidates. But he always said he loves me and if I weren't too old to have children, he'd marry me. Now he's found someone else and he wants me to be at the wedding. Part of me wants to go and cheer him on, because he's partly like a son to me. Part of me wants to go and create a scene, because I do love him. And part of me doesn't want to go because it hurts. What should I do? Yours sincerely, Catherine
