This. I'm usually pretty pedantic about this sort of thing, but don't submit very often, and wasn't aware of the 80 char limit. Forced to pare a more descriptive headline and get back to work, I made a mistake.

It looks as though it's been replaced with the actual headline now anyway, though I don't think that highlights the most interesting part of the article.

I don’t think it does.

If it did, then the LHS and RHS would be functionally identical, or nearly so. But they aren’t, because you can’t rewrite “New use of existing technology” to “man revived after 96 minutes w/out a pulse” in many contexts, or vice-versa, without a change in meaning.

English uses “is” for simple identity, but not as often as it uses it for other things.* Indiscriminately replacing “is” with “=” or “==” is usually only going to confuse any math or programming person trying to take it seriously. And if you don’t mean it to be taken seriously, using “==” for an equally long and much more ordinary word is just silly.

* For example, copula: http://en.wikipedia.org/wiki/Copula_(linguistics) . This is the form of “is” in “Denver is south of here”. Clearly Denver is not equal to to predicate of relative southernness, or I could say “San Diego is Denver”.
