Guppy love

WHEN it comes to picking a mate, female guppies go wild over males with spots, especially orange ones. Now biologists think they've found the reason—the male fish could be mimicking fruit. Helen Rodd from the University of Toronto and her team showed different-coloured plastic discs to wild guppies. They found that both males and females …

Those created by large aircraft can present a severe hazard to smaller aircraft (New Scientist, 24 November 2001, p 13) . Given the nightmare of a problem that air traffic control centres must have in sorting out aircraft over …

Feedback

AS DOCTORS know only too well, as soon as you give a syndrome a name it starts popping up all over the place. So at the end of last year, when we coined the term semiopathy—the phenomenon of reading inappropriate emotions into signs—dozens of readers discovered that they were semiopathologists.
