A study published this week provides the most definitive evidence to date disproving previous reports that used molecular testing methods such as qPCR to establish a link between chronic fatigue syndrome, or myalgic encephalomyelitis, and various murine leukemia viruses.

Two recently published studies suggest that laboratory contamination was the likely cause of previous evidence linking murine viruses to CFS, highlighting the fact that researchers conducting PCR experiments should be extremely cautious about both inherently contaminated commercial reagents and contamination from laboratory manipulation.

In Nucleic Acids Research this week: ProTraits includes genetic, phenotypic data on bacteria, archaea; Candida albicans assembly 22; and more.

The Wall Street Journal reports that researchers are looking beyond Cas9 for CRISPR editing.

Familial DNA searches in criminal cases are winning over some critics, the Los Angeles Times reports.

In PNAS this week: miR-515 levels higher in women with preeclampsia, horizontal gene transfer in parasitic plants, and more.
