Hide the first item hover when hovering over any other item

Hey. This is the link to the page About and I’m talking about the second section under Published Work. I have been able to implement the custom code to show the description of the first item on page load but I’m not able to figure out what I need to do to hide the first item description on hovering over any other item.
