New clues for treatment of disease that causes accelerated agingThere is renewed hope for therapy of a rare genetic condition that causes rapidly accelerated aging and leads to an average life expectancy of 13 years.
Researchers studying the genes of two infants who died of mysterious illnesses found the infants had mutations in LMNA, the same gene altered in patients with the premature aging condition progeria. But the infants' unusual mutations caused them to make a number of more bad copies of the........Go to the Research news blog (Added on 5/2/2007 9:56:17 PM)

Study shows children less prone to false memoriesIn the 1980's, a spate of high profile child abuse convictions gave way to heightened concern about false memory reports given by children. Take, for example, the case of Kelly Michaels, a preschool teacher who was convicted on 115 counts of sexual abuse based on the testimony of 20 of her pupils. After serving seven years of her 47 year sentence, Michaels' conviction was overturned after the techniques used to interview the children were shown........Go to the Pediatric news blog (Added on 4/30/2007 6:58:45 PM)
