Box 1. Really Simple Syndication separates content from websites for efficient reading

To keep track of ever-increasing amounts of content on the web, scientists are taking advantage of RSS (for Really Simple Syndication or Rich Site Summary). RSS is yet another way of publishing data online. When a new post is made on an RSS-enabled site, that entry appears on the web page as well as in the RSS feed. This feed is composed entirely of the content of that post plus some metadata for tracking purposes. It can be read in a feed reader or aggregator, such as RSS Owl, Google Reader, or NewsFox (see illustration). The advantage of this is that news and updates from many different sites are collected in one place for easy navigation and filtration. Articles and entries appear in a system that resembles a familiar email inbox. Letting the computer automatically collect reading material from a set of favorite sites is far more efficient than tracking all those sites manually (Scarsbrook, 2007).
