Template Library Version 1.4.1

$this refers to the current controller, not some other controller. Therefore, $this->news would need to be a property (or model or library etc) of the current controller.

In your case, I speculate thta you most likely meant calling a show() method from a news model in $this controller. You will need to load the news model, or rework your controllers or read up on the CI and PHP documentation.
