Two studies with possibly interesting ethics

Two studies came out this morning that I thought worth mentioning. The first on how strife in a relationship can affect healing times. The second is about IQ and genetics. It appears that if a male has one variant, IGF2R, of a growth factor, that male is 20 points lower on IQ.

So how to make normal science controversial? Its just data folks? The IQ is pretty straight forward--no one likes the idea of say tracking kindergardners based on a genetics test. But it seems like there is potential in the other study that I just can't identify.
