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 observation of an elusive sub-atomic particle known as the Higgs boson has been heralded by the journal Science as the most important scientific discovery of 2012. This particle, which was first hypothesized to exist more than 40 years ago, holds the key to explaining how other elementary particles such as electrons and quarks (those that aren’t made up of smaller particles) get their mass.
