Could be a case of modeler bias.  Just look at the name of the  
institute. This is like having a Jessie Helms endowed chair in the  
therapeutic benefits of tobacco.

The first determination of the absolute configuration of an organic

tetrahydrate, Na(+).Rb(+).C(4)H(4)O(6)(2-).4H(2)O, but the atomic  
coordinates are not available in the public literature. This  
structure has therefore been redetermined using current equipment.  
The most up-to-date techniques for the determination of the absolute  
configuration have been applied and the question posed in the title  
can be answered with an unequivocal ;yes'."
