Omitting the “The” is a style used by newspapers (paper and on-line) for headlines. It is a convention that saves space and makes the headline copy cleaner and more impactful. Seeing “The” in every headline on the page would become tedious. In the second example you give you can see that adding “The” makes the headlines unnecessarily long, by also forcing you to put the verbs in past tense, potentially making the headlines even longer. The actual article below any headline should use conventional grammar, including “the” and past tense as appropriate.
