Science news of the week: scientists have finally invented an odourless breed of durian, the tropical fruit which is popular in the East Indies, but entirely impossible to obtain in Britain. It smells like a potent mix of vomit and custard, and is banned from the cargo holds of every airline because of that. In Malaysia, several people are killed by durian every year, not because of the smell, but because they are large, spiky, and grow high up in trees. My former Malaysian flatmate would send me news clippings about deaths rising at the start of each durian season. Note to European publishers: start getting those durian recipe books ready now!
