Vaccine link to autism dismissed
In February, Lancet formally retracted a 1998 study that had kindled a storm of opposition to vaccines (SN Online: 2/3/10). The research suggested that autism arose in a handful of children after the kids received shots to prevent measles, mumps and rubella. The study’s lead author committed several ethical breaches, and the selection of participants in the study may have been biased, the U.K. General Medical Council reported in January following an investigation. Following suit, Lancet retracted the paper, noting that “several elements” of the study were incorrect. Alarms that the study raised about vaccines, though, continue to reverberate despite subsequent research in Britain, Japan and Finland that has found no connection between the MMR vaccine and autism.

Telltale smudge Imaging technology reveals that Thomas Jefferson made a last-minute revision to the Declaration of Independence (below), calling colonists citizens instead of subjects (SN Online: 7/3/10). A Library of Congress scientist spotted a smudge on an early draft of the historic document, then discovered what had been erased by photographing the paper in 13 different wavelengths of light and subjecting the images to 10 hours of computer processing.
