You can use Publication_Date <= "#now" AND Expiration_Date > "#now" or instead of now you need to type the data range. Note that this are static values. If you want to do it dynamically you need a custom control that inherits from the base class ( say NewsView) and you need to override CreateChildControls(). Before the base you need to include the filter expression logic. There is a built-in class ContentFilterBuilder that you can use.
