Science journalism is an increasingly imperilled occupation that, perversely, is needed now more than ever. In a world where both citizens and advertisers increasingly control their own delivery of information via online channels, the kind of legacy mass media that have long served as the principal employers of science journalists – newspapers and magazines – are faltering in many countries. Journalists cut loose from these media organisations are scrambling to find their footing elsewhere. It will be years before successful models for delivery of substantive science journalism emerge from the bevy of experiments now under way.
