The Illustrated Guide to Epigenetics. 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. 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. Their analyses identified more than 7,700 insertion sites for L1, the best-characterized retrotransposon family that was already known to be active in brain cells.

CANTANKEROUS NEIL DEGRASSE TYSON: Yep, whatever. CHEERFUL NEIL DEGRASSE TYSON: As they get older, those differences can get more pronounced. Two people start out the same but their appearance and their health can diverge. CANTANKEROUS NEIL DEGRASSE TYSON: No. CHEERFUL NEIL DEGRASSE TYSON: Yeah. CANTANKEROUS NEIL DEGRASSE TYSON: And don't our genes make us who we are? CHEERFUL NEIL DEGRASSE TYSON: Well they do, yes, but they're not the whole story.

Rubinsteinjrubinstein@rubenstein.com 212-843-828723andMe Inc. MOUNTAIN VIEW, CA – January 11, 2011 – 23andMe has released its first annual list of what it felt to be the 10 most interesting and significant genetic findings in 2010, as part of an ongoing journey to understand the role of genetics in personal health and human development. "Our understanding of the human genome is accelerating at a phenomenal rate," stated Anne Wojcicki, co-founder and CEO of 23andMe. Customers of 23andMe have the opportunity to learn about how their genetics can influence their individual health traits, risk for developing certain diseases and conditions, reactions to a variety of medications, and ancestry. 1.

Learn.Genetics™ Sleep: Genes Cause People to React Differently to Lack of Sleep, Says Study. <br/><a href=" US News</a> | <a href=" 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. About 25 percent of the general public has the genetic variant, called DQB1 *0602, but only a small percentage of them actually suffer from sleep problems. Cracking the Code of Life.

But when scientist Eric Lander looks at this he sees stories. ERIC LANDER (Whitehead Institute/MIT): The genome is a storybook that's been edited for a couple billion years. And you could take it to bed like A Thousand and One Arabian Nights, and read a different story in the genome every night. ROBERT KRULWICH: This is the story of one of the greatest scientific adventures ever, and at the heart of it is a small, very powerful molecule, DNA. For the past ten years, scientists all over the world have been painstakingly trying to read the tiny instructions buried inside our DNA. J.
