Illustrations by Joe Kloc This month marks the ten-year anniversary of the sequencing of the human genome, that noble achievement underpinning the less noble sales of 23andMe's direct-to-consumer genetic tests. To commemorate the scientific occasion, we've created an illustrated introduction to one subfield of genetics likely to produce even more dubious novelty science projects someday: epigenetics. What is epigenetics?
The Ductile Helix: "Jumping Genes" May Influence Brain Activity Mobile DNA molecules that jump from one location in the genome to another may contribute to neurological diseases and could have subtle influences on normal brain function and behavior, according to a study published October 30 in Nature. (Scientific American is part of Nature Publishing Group.) Retrotransposons are mobile genetic elements that use a copy-and-paste mechanism to insert extra copies of themselves throughout the genome. First discovered in plants about 60 years ago, they are now known to make up more than 40 percent of the entire human genome and may play an important role in genome evolution (pdf). Researchers from the Roslin Institute in Edinburgh, Scotland, have now comprehensively mapped retrotransposon insertion sites in the genomes of normal human brain cells for the first time.

Sleep: Genes Cause People to React Differently to Lack of Sleep, Says Study <br/><a href="http://abcnews.go.com/us">ABC US News</a> | <a href="http://abcnews.go.com/business">ABC Business News</a> Copy No matter how little they sleep, some people can keep a skip in their step while others will yawn and struggle through the day. A new study from the University of Pennsylvania School of Medicine found that the reason could be in our genes. Researchers found that healthy people with one particular genetic variant were generally sleepier than those without the gene.
