It's a single study. Single studies aren't used to set health policy because until several groups have replicated a finding it can easily be wrong simply by chance (with the standard 95% confidence levels 5% of studies will be wrong simply by chance.)
It's an interesting finding but until it's replicated by other groups, in other species, I'm not st all worried.
Paracetamol used correctly has a good record. Drugs do get constantly monitored after release and all adverse events are reported and collated. If paracetamol caused significant effects we'd know it. That doesn't rule out subtle effects of course but for me, a single study is not enough.
And as nooka says, media reporting of science is truly dire. Even the broadsheets are terrible at it.
Our lab once found a gene modification that when bred into nice that naturally had a mutation found in humans which causes early death from colon cancer, the mice lived twice as long. Still died early but it seemed to offset the effects a bit.
This was reported in the media as we'd cured aging. Sigh...
