I couldn't find the direct causal link mentioned above in the article.. just that they couldn't figure out what was the link.. and it doesn't seem that hard to dream up some explanations..

example: You work at a company, your friends work at the same company, company goes bankrupt, you all grow fatter at the same time.
exampl2: You go to college, your friends are of your age, and also go to college, you all grow a beer belly.

Ramanujian's Deathbed Problem Cracked 205

Jake's Mom sends word of the serendipitous solution to a decades-old mathematical mystery. Researchers from the University of Wisconsin have unraveled a major number theory puzzle left at the death of one of the twentieth century's greatest mathematicians, Srinivasa Ramanujan. From the press release: "Mathematicians have finally laid to rest the legendary mystery surrounding an elusive group of numerical expressions known as the 'mock theta functions.' Number theorists have struggled to understand the functions ever since... Ramanujan first alluded to them in a letter written [to G. H. Hardy] on his deathbed, in 1920. Now, using mathematical techniques that emerged well after Ramanujan's death, two number theorists at the University of Wisconsin-Madison have pieced together an explanatory framework that for the first time illustrates what mock theta functions are, and exactly how to derive them."
