'Caffeine in the genes'

A recent study published in the journal PLoS Genetics links the extent of one's caffeine craving and the amount of caffeine people regularly consume to two particular genes.

Everybody has these genes, according to Rachael Rettner, author of the LiveScience article "Caffeine Craving Linked to Genetics." But different people may have different versions of these genes, and that's what determines someone's susceptibility to excessive caffeine intake.

Rettner's article was published yesterday at 6:58 PM ET. To read it, click here.
