What is RSS?
RSS is a free web service that allows you to subscribe to your favorite sites and receive their content directly as soon as it’s posted, either via a desktop newsreader or an online service (such as Bloglines or Feedly).
For more general information about RSS and newsreaders, see the Wikipedia entry for RSS.
RSS Feeds on PopSci.com
Here on the new PopSci.com, we’re practically swimming in RSS feeds. As you can see, we’re now cataloging our content both by category (what you see in the black bar on every page) as well as by keyword, or tag. This way, it’s possible to subscribe to any and all content that may interest you. Only want to read about robots? Simply click on the ‘robots’ tag anywhere on the site, then click its orange RSS button on the robots page to subscribe. Easy!
Below are a list of general feeds you can subscribe to, but keep in mind that wherever you see an orange RSS icon there is a feed to subscribe to.
