Salk study finds stress triggers widespread epigenetic changes that aid in disease resistance It was long thought that methylation, a crucial part of normal organism development, was a static modification of DNA that could not be altered by environmental conditions. New findings by researchers at the Salk Institute for Biological Studies, however, suggest that the DNA of organisms exposed to stress undergo changes in DNA methylation patterns that alter how genes are regulated. The...

U.S. scientists say they have proposed a definition of epigenetics -- a new research field focusing on heritable genetic alterations not caused by DNA. Ali Shilatifard of the Stowers Institute for Medical Research met with colleagues in December at the Cold Spring Harbor Laboratory in New York to develop a consensus definition of epigenetic traits for consideration by the broader research community. Shilatifard said the definition is intended to address confusion within the scientific...

U.S. scientists say they might have found the genetic cause of so-called late onset diseases. Researchers at Johns Hopkins University discovered epigenetic marks on DNA -- chemical marks other than the DNA sequence -- change over a person's lifetime and the degree of change is similar among family members. The scientists suggest that overall genome health is heritable and that epigenetic changes occurring over one's lifetime might explain why disease susceptibility increases with age....


Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
