Each subsite has an Atom feed for the up to 10 latest articles.
Feeds used to be quite common, though most people now use their social media programs' feeds for their news and information instead. Most feed readers will work with feeds in RSS or Atom formats, though RSS has become the generic term for them.
While feed plugins are available for Chromium-based browsers and Firefox, they do not tend to have the simplicity of the Internet Explorer format, and require registration to use. If you have an outlook.com account, it allows RSS feeds to be defined in Outlook and they are listed just like emails, including bolding for new items.
