How neurons get wired
University of Arizona researchers have discovered 2 different polarities in the same signaling protein, each telling a nerve cell which end is which. The findings could someday help improve therapies for spinal injuries and neurodegenerative diseases.

eRNAs may provide new avenues for gene therapy
A study investigating the function of the newly discovered enhancer RNA molecules (eRNAs), may open new avenues for gene therapy. Altering the production and function of these molecules could affect the expression of genes and as a consequence, possibly alter the progression of various diseases.

"Grammar" Plays Key Role in Activating Genes
Researchers have probed deep into the cell’s genome, beyond the basic genetic code, to begin learning the “grammar” that helps determine whether or not a gene gets switched on to make the protein it encodes.

DHA-enriched formula linked to better cognitive development
Infants fed formula enriched with long-chain polyunsaturated fatty acids (DHA and ARA) from birth to 12 months, scored significantly better than a control group in intelligence performance tests between the ages of 3 to 6 years.

Key protein identified that affects aging
New findings could lead to the development of therapeutic agents for age-related diseases.

New gene repair technique advances regenerative medicine
Using human pluripotent stem cells and DNA-cutting protein from meningitis bacteria, researchers from the Morgridge Institute for Research and Northwestern University have created an efficient way to target and repair defective genes.

Inducing or augmenting labor may increase risk of autism
Pregnant women whose labors are induced or augmented may have an increased risk of bearing children with autism, especially if the baby is male, according to a large, retrospective analysis by researchers at Duke Medicine and the University of Michigan.

Mouse heart beats with human heart cells
For the first time, a mouse heart was able to contract and beat again after its own cells were stripped and replaced with human heart precursor cells, by scientists from the University of Pittsburgh School of Medicine.

How genes tell cell 'Read me now!'
Stowers research shows that DNA sequences at the beginning of genes contain more information than previously thought.

Predicting Individual Breast Cancer Risk May Be Possible
An international collaboration led by the Harvard Stem Cell Institute has discovered why women who give birth in their early twenties are less likely to eventually develop breast cancer than women who don't, triggering a search for a way to confer this protective state on all women.

Rethinking 'The Code'
Rules governing developmental genes in mouse embryonic stem cells do not simply tell a gene whether to be "on" or "off."

Molecule needed in nerve-cell migration implicated in brain cancer
The invasion of brain-tumor cells into surrounding tissue requires the same protein molecule that neurons need to migrate into position while differentiating and maturing.

New drug improves walking for Duchenne MD patients
Results from a clinical trial of the drug eteplirsen, designed to treat Duchenne muscular dystrophy, suggest that the therapy allows participants to walk farther than people treated with placebo and dramatically increases production of a protein vital to muscle growth and health.

HSCI expands human genome map with epigenetics
Ten years ago, scientists announced the end of the Human Genome Project, the international attempt to learn which combination of four nucleotides—adenine, thymine, cytosine, and guanine—is unique to homo sapien DNA. Now they are adding the study of epigenetics.

Simple math sheds new light on how to convert glucose
One of the most basic and intensively studied processes in biology—one detailed in textbooks for decades—has gained a new level of understanding, thanks to applying simple math to a problem scientists never before thought could benefit from mathematics.
