Analyzing DNA from Pap smears could help detect endometrial and ovarian cancer, according to a new study appearing in the 9 January issue of the journal Science Translational Medicine.

The finding could be a potentially life-saving screening tool for women. The routine Pap smear, which allows doctors to detect abnormal cells in a woman’s cervix, was recently updated to screen for human papillomavirus or HPV using DNA testing.

The link between the XMRV retrovirus and patients with chronic fatigue syndrome is probably the result of laboratory contamination, according to two new studies published today by the journal Science.

In 2009, a report that patients with chronic fatigue syndrome were infected with XMRV attracted considerable interest, but subsequent studies published in other journals by independent scientists failed to detect XMRV in other groups of patients with the condition.
