CANTANKEROUS NEIL DEGRASSE TYSON: Yep, whatever. CHEERFUL NEIL DEGRASSE TYSON: As they get older, those differences can get more pronounced.

Protecting People Walter and Eliza Hall Institute of Medical Research DNA sequencing is becoming faster and more sophisticated, making it easier to determine the best treatment based on genetics of the disease and the individual. What is personalised medicine? Every human is unique, and we often differ in how we develop diseases and respond to treatments. Personalised medicine aims to tailor treatments to achieve the best outcome for individual patients, rather than treating patients with a ‘one size fits all’ approach.
New Genetic Twist: 4-Stranded DNA Lurks in Human Cells Sixty years after scientists described the chemical code of life — an interweaving double helix called DNA — researchers have found four-stranded DNA is also lurking in human cells. The odd structures are called G-quadruplexes because they form in regions of deoxyribonucleic acid (DNA) that are full of guanine, one of the DNA molecule's four building blocks, with the others being adenine, cytosine, thymine. The structure comprises four guanines held together by a type of hydrogen bonding to form a sort of squarelike shape.
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.

Genomic testing paves way for personalised medicine Becky Harvey is diagnosed with Syndrome Without a Name. Source: News Limited AN Australian-first program paving the way for “personalised medicine” is being set up in Melbourne, aiming to offer faster, cheaper and more accurate diagnoses for more patients. Cracking the Code of Life Cracking the Code of Life PBS Airdate: April 17, 2001 ROBERT KRULWICH: When I look at this—and these are the three billion chemical letters, instructions for a human being—my eyes glaze over. But when scientist Eric Lander looks at this he sees stories.
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. What is epigenetics?
Allergy and Infectious Diseases The National Institute of Allergy and Infectious Diseases (NIAID) conducts and supports basic and applied research to better understand, treat, and ultimately prevent infectious, immunologic, and allergic diseases. For more than 60 years, NIAID research has led to new therapies, vaccines, diagnostic tests, and other technologies that have improved the health of millions of people in the United States and around the world. NIAID is one of the 27 Institutes and Centers of the National Institutes of Health (NIH). Genomics > Table of Pharmacogenomic Biomarkers in Drug Labeling Pharmacogenomics can play an important role in identifying responders and non-responders to medications, avoiding adverse events, and optimizing drug dose. Drug labeling may contain information on genomic biomarkers and can describe: Drug exposure and clinical response variabilityRisk for adverse eventsGenotype-specific dosingMechanisms of drug actionPolymorphic drug target and disposition genes The table below lists FDA-approved drugs with pharmacogenomic information in their labeling.
The Fruit Fly and Genetics Personals: ♀ FF, Se/E/Dp, seeks ♂ FF, +/+/+ for short term relationship. Enjoys romance, fermentation, and long walks on the peach... You know those annoying little bugs that like to get in your fruit if you leave it on the counter? Well they're called Drosophila melanogaster (or just fruit flies) and they've been used to study genetics for over 100 years. This interactive website is designed to introduce biology students to research on model organisms while reviewing genetics basics. Learning about Genetics Using Flies
