Studies that reach HN and other pop places usually have a lot in common: they link a widespread, modifiable and 'catchy' factor (like sleep, sugar/meat etc consumption, human relations) with a single sensational end point (death), and involve 5/6-figures number of participants. Another common one is a huge confounding spill that makes them useless for practical decisions but valuable for further, more rigorous research design.
