The South African Centre for Infectious Disease Surveillance is piloting a program to use smartphone technology to report and respond to infectious disease outbreaks.

Getting away from daily publishing helps local newspapers focus on serving their audience. The Quoddy Tides, a family-owned newspaper in Eastport, Maine, publishes only twice monthly.

By avoiding the 24-hour news cycle, the newspaper can focus on local discourse and civic engagement.
