While I have no love for the Herald's style & quality of journalism (e.g.: when the Globe fired a populist columnist for plagiarism, the Herald gleefully scooped him up), I do enjoy their screaming headlines. Short, pithy & fun -- though accuracy and fairness clearly aren't strong selection criteria.
The headlines in scientific journals and newswires tend to be long on long and short on punchy. Perhaps some is an urge to cram as many keywords as possible into the title, and perhaps some is a deliberate desire for dryness. While these titles often fit the purpose, it isn't uncommon to be able to rewrite one for more zazz, especially if you are emailing abstracts to a colleague rather than editing a journal.
Of course, one advantage of long and ponderous is a single possible meaning -- spell it out in detail, and nobody can misinterpret it accidentally -- or deliberately. Rarely can a scientific paper title or newsfeed item become a candidate for Jay Leno's headlines schtick, but it does happen. GenomeWeb is usually a good provider of useful news, but the other week I got a grin out of a headline that could be seen as a politically incorrect description of enlisting patients in their own cause
Other times, someone does put together a clever headline that grabs the eye -- usually with a clever name for a hypothesis
However, I do not like titles to mislead.
The calorically restricted ketogenic diet, an effective alternative therapy for malignant brain cancer.
If you skip to the bottom of the abstract, it's even worse
This preclinical study indicates that restricted KetoCal(R) is a safe and effective diet therapy and should be considered as an alternative therapeutic option for malignant brain cancer.
It's an interesting idea (with precedent in the literature), but 'safe & effective'? The key term left out of the title is 'xenograft mice'. Only proven so if you are a xenografted mouse, a population for which a huge variety of 'cures' already exist. The abstract as a whole isn't bad, but I'll hardly be shocked if I start seeing ads touting the final sentence without qualification.
