This is the kind of press release that makes me want to hurl flowerpots at closed windows. The title, "Constant lighting may disrupt development of preemies' biological clocks" would lead most reasonable folks to the conclusion that premature babies were somehow involved in the article.
But no. It's about baby mice, which are supposed to be comparable to human preemies because they're born at an earlier stage of development. I can't comment on that - obviously the funders of the study thought it was a fair assumption. But c'mon, if the study did not in fact look at premature human babies, then don't put it in the title, because some people won't read any further than that, and we frankly don't know yet whether the results can be extrapolated.
