Science in the mass media is usually interpreted in terms of tradition
al, linear, 'dissemination and translation' models of science communic
ation. Using the cold fusion saga that began in 1989, this paper argue
s that communication among scientists uses many media, which interact
in complex ways. A more appropriate model for modern science must acco
unt for the permeable boundaries between formal publications preprints
, electronic computer networks, fax machines, mass media presentations
and other forums for scientific discussions. The new model must accou
nt for the paradox that increased communication activity may be associ
ated with instability rather than stability, at least in the prelimina
ry periods of a scientific controversy.
