Is there a difference between "seeks" and "tries"?

I am seeking guidance on using seek vs try when speaking.

This sentence is talking about what a research study is attempting to discover:

A flu challenge study tries to understand what happens when a person is infected with flu virus and how the body controls the infection.

or

A flu challenge study seeks to understand what happens when a person is infected with flu virus and how the body controls the infection.

Is there a difference?
