Histone-Modifying Proteins, Not Histones, Remain Associated With DNA Through Replication
August 23, 2012 — A study of Drosophila embryos found that parental methylated histones are not transferred to daughter DNA. Rather, after DNA replication, new nucleosomes are assembled from newly synthesized ... > full story -
Human-Chimp Genetic Differences: New Insights Into Why Humans Are More Susceptible to Cancer and Other Diseases
August 23, 2012 — Ninety-six percent of a chimpanzee's genome is the same as a human's. It's the other 4 percent, and the vast differences, that has intrigued researchers. For instance, why do humans have a high risk ... > full story -
Archived Guthrie Cards Find a New Purpose
August 22, 2012 — Over the last 50 years, the spotting of newborn's blood onto filter paper for disease screening, called Guthrie cards, has become so routine that since 2000, more than 90% of newborns in the United ... > full story -
Molecular 'Movies' May Accelerate Anti-Cancer Drug Discovery
August 17, 2012 — Using advanced computer simulations, researchers have produced moving images of a protein complex that is an important target for anti-cancer ... > full story -
Acute Stress Alters Control of Gene Activity: Researchers Examine DNA Methylation
August 15, 2012 — Acute stress alters the methylation of the DNA and thus the activity of certain ... > full story -
Planting the Seeds of Defense: Stress Triggers Widespread Epigenetic Changes That Aid in Disease Resistance
August 7, 2012 — 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, however, ... > full story -

Sick from Stress? Blame Your Mom… And Epigenetics
July 31, 2012 — If you're sick from stress, a new research report suggests that what your mother ate -- or didn't eat -- may be part of the ... > full story -
What 10,000 Fruit Flies Have to Tell Us About Differences Between the Sexes
July 19, 2012 — What do you get when you dissect 10,000 fruit fly larvae? Scientists have discovered a way in which cells can adjust the activity of many different genes at once. Their findings overturn commonly ... > full story -
Discovery of 'Hopping' of Bacterial Enzyme Gives Insight Into Gene Expression
July 18, 2012 — Researchers' discovery of a variation of an enzyme's ability to "hop" as it moves along DNA, modifying the genetic material of a bacteria -- and its physical capability and behavior -- holds much ... > full story -
Mechanisms That Allow Embryonic Stem Cells to Become Any Cell in the Human Body Identified
July 18, 2012 — New research sheds light on pluripotency -- the ability of embryonic stem cells to renew themselves indefinitely and to differentiate into all types of mature cells. If scientists can replicate the ... > full story
