In an extensive sleuthing expedition that looked back nearly 20 years, two collaborating research teams contend that they have evidence that xenotropic murine leukemia virus — related virus (XMRV) resulted from the chance recombination of pieces of two mouse viruses in lab experiments and that the connections to human disease are spurious.

To conduct their investigation into the ways in which the mutations might inform Alzheimer's treatments, Dr. Weihong Song and his team injected a group of mice with a virus that elicited the mutation associated with the Italian populace and gave another group of mice a virus to create the Icelandic mutation.

A theory linking chronic fatigue syndrome (CFS) to an infectious mouse virus known as XMRV has taken a second major hit. (sciencemag.org)
