DNA methylation changes in pregnancy persist into childhood—and perhaps last forever
Even before they are born, babies accumulate changes in their DNA through a process called DNA methylation that may interfere with gene expression, and in turn, their health as they grow up. But until now it's been unclear just how long these changes persist.

Youthful stem cells from bone can heal the heart
Findings raise hope for new heart therapies from stem cells found in cortical, or compact, bone.

New genetic defect, an inability to process Vitamin B12
An international team of scientists has discovered a new disease related to an inability to process Vitamin B12. A Colorado boy and his family play a key role in uncovering this rare, but devestating disorder.

Reversing Down syndrome-like learning deficits in mice
Researchers at Johns Hopkins and the National Institutes of Health have identified a compound that dramatically bolsters learning and memory when given to mice with a Down syndrome-like condition on the day of birth.

Proteins in histones might influence cancer
Spool-like proteins called histones play a crucial role in packaging the nearly seven feet of DNA found in most human cells. A new study shows that a group of histones that are thought to behave the same actually are functionally distinct proteins.

The 'weakest link' is the aging protein
Salk and Institute and The Scripps Research Institute find long-lived proteins lead to understanding the molecular basis of cell aging.

Potential test to predict risk of pre-eclampsia
Researchers have identified proteins in the blood that could be used to predict whether a woman in her first pregnancy is at increased risk of developing pre-eclampsia.

Death by asexuality
For the first time, ground-breaking research from evolutionary biologists at Indiana University (IU) shows how asexual lines in a species of flea are doomed.

What triggers regeneration in planarian?
Unlike humans, planarian flatworms have the remarkable ability to regrow any missing body part, making them an ideal model of the molecular basis of regeneration.

Shutting off neurons helps bullied mice overcome symptoms of depression
Findings point to new potential drug target—GABA neurons—to treat patients with depression and other mood disorders.

Now hear this: Compound prevents noise-related hearing loss
New research suggests that excessive noise activates certain cells in the ear causing them to detach and damage the blood barrier.

Boy interrupted: Y-chromosome mutations reveal how precariousness is 'male'
The idea that men and women are fundamentally different from each other is widely accepted. And throughout the world, this has created distinct ideas about which social and physical characteristics are necessary in each gender to maintain healthy human development.

Little changes produce large effects
Scientists at the University of York in the United Kingdom, have discovered that very small chemical changes in our diet cause very large effects. Evidence comes from plant products tested on the human immune system.

Progeria, cell senescence, and aging
Penn study links epigenetics, aging, and mutations in nuclear proteins to create a better understanding of cancer and rare disorders.

Stem cells need 'helper cells'
Engineered “helper cells” improve survival rate of transplanted stem cells, mouse study finds.
