Study Shows Key Role Environment Plays in Developing Reading Skills

While genetics play a key role in children’s initial reading skills, a new study of twins is the first to demonstrate that environment plays an important role in reading growth over time.

New Approach Precisely Tracks Evolution’s Footprints in the Human Genome

Fossils may provide tantalizing clues to human history but they also lack some vital information, such as revealing which pieces of human DNA have been favored by evolution because they confer beneficial traits — resistance to infection or the ability to digest milk, for example. Now, researchers describe a method for pinpointing these preferred regions that offers greater precision and resolution than ever before, and the possibility of deeply understanding both our genetic past and present.

Rules Governing RNA's Anatomy Revealed

University of Michigan researchers have discovered the rules that dictate the three-dimensional shapes of RNA molecules, rules that are based not on complex chemical interactions but simply on geometry.

Weight Is a Prickly Problem: a Key Role for Hedgehog Signaling in Controlling Fat Storage

Researchers at the Institute of Molecular Biotechnology in Vienna (Austria) have identified a key regulator of white versus brown adipose cell fate. The findings are reported in the January 7 issue of the journal Cell.

Canine Compulsive Disorder Gene Identified in Dogs Gene Shares Family with Recently Targeted Gene for Autism

A canine chromosome 7 locus that confers a high risk of compulsive disorder susceptibility has been identified through a collaboration between the Behavior Service at the Cummings School of Veterinary Medicine, the Program in Medical Genetics at the University of Massachusetts Medical School and the Broad Institute at the Massachusetts Institute of Technology. The findings are published in the January 2010 edition of Nature Molecular Psychiatry.

It’s Not Only the Gene That Counts, But How You Use It

Scientists at the University of Idaho have discovered not only that different species sometimes use the same gene to produce the same adaptation, but also that how they use it can lead to different outcomes.

Study Identifies Genetic Predeterminants for Diabetes in African-Americans

Researchers at the University of North Carolina at Chapel Hill School of Medicine say a recent discovery suggests that inherited genetic variations exist between whites and blacks living in the U.S., leading to less efficient metabolism of glucose and predisposition to diabetes in blacks.

Two Genes That Drive Aggressive Brain Cancers Discovered

A team of Columbia scientists have discovered two genes that, when simultaneously activated, are responsible for the most aggressive forms of human brain cancer. This finding was made possible by the assembly of the first comprehensive network of molecular interactions that determine the behavior of these cancer cells.

Nationwide Children’s Hospital Selected as Biospecimen Core Resource for The Cancer Genome Atlas

Nationwide Children’s Hospital recently was awarded an initial $5.5 million contract from the National Cancer Institute (NCI) to serve as a Biospecimen Core Resource (BCR) for The Cancer Genome Atlas (TCGA), a program co-managed by the NCI and the National Human Genome Research Institute (NHGRI), both part of the National Institutes of Health (NIH).
