Here's the CSS code that goes in the HEAD of your document: 
<style type="text/css">
	<!--
	.newsbody {
font: 7pt arial, sans-serif;
font-weight: italic;
background: transparent;
	}
	-->
</style>
And here's how it makes the newsfeed look (this affects the whole news text, titles and descriptions, so this example shows the "long" version*):

Note that you can change the font size by changing the following line in the CSS code: 

font: 9pt arial, sans-serif;
Likewise, you can also change the other variables, such as font-weight, background color, etc.

* Here's what the code for the long version above would look like:
