Quadruple helix DNA found in living human cells — and it may be linked to cancer. Researchers remove extra chromosome from Down’s syndrome cells. Could a gene therapy be next? Ewan's Blog; bioinformatician at large: ENCODE: My own thoughts. 5 September 2012 - Today sees the embargo lift on the second phase of the ENCODE project and the simultaneous publication of 30 coordinated, open-access papers in Nature, Genome Research and Genome Biology as well as publications in Science, Cell, JBC and others. The Nature publication has a number of firsts: cross-publication topic threads, a dedicated iPad/eBook App and web site and a virtual machine.
This ENCODE event represents five years of dedicated work from over 400 scientists, one of whom is myself, Ewan Birney. I was the lead analysis coordinator for ENCODE for the past five years (and before that had effectively the same role in the pilot project) and for the past 11 months have spent a lot of time working up to this moment. There were countless details to see to for the scientific publications and, later, to explain it all in editorials, commentary, general press features and other exotic things.

Back in 2001, the Human Genome Project gave us a nigh-complete readout of our DNA. Somehow, those As, Gs, Cs, and Ts contained the full instructions for making one of us, but they were hardly a simple blueprint or recipe book. The genome was there, but we had little idea about how it was used, controlled or organised, much less how it led to a living, breathing human.
That gap has just got a little smaller. A massive international project called ENCODE – the Encyclopedia Of DNA Elements – has moved us from “Here’s the genome” towards “Here’s what the genome does”. Over the last 10 years, an international team of 442 scientists have assailed 147 different types of cells with 24 types of experiments. Their goal: catalogue every letter (nucleotide) within the genome that does something. For years, we’ve known that only 1.5 percent of the genome actually contains instructions for making proteins, the molecular workhorses of our cells. And what’s in the remaining 20 percent? The 3-D genome. Williams syndrome. Williams syndrome (WS or WBS; also Williams–Beuren syndrome or WBS) is a rare neurodevelopmental disorder characterized by a distinctive, "elfin" facial appearance, along with a low nasal bridge, an unusually cheerful demeanor and ease with strangers; developmental delay coupled with strong language skills; and cardiovascular problems, such as supravalvular aortic stenosis and transient hypercalcaemia.
Cause[edit] Signs and symptoms[edit] The most common symptoms of Williams syndrome are mental disability, heart defects, and unusual facial features. Other symptoms include failure to gain weight appropriately in infancy (failure to thrive) and low muscle tone. Most individuals with Williams syndrome are highly verbal relative to their IQ, and are overly sociable, having what has been described as a "cocktail party" type personality.[8] Individuals with WS hyperfocus on the eyes of others in social engagements. Physical[edit] 10-year-old boy with Williams syndrome Nervous system[edit] Study: The older the dad, the more mutations he’s likely to pass on. Human brain shaped by duplicate genes. Ann Cutting / GETTY IMAGES Could duplicated genes explain why you can read this?
Humans walk on two feet and (mostly) lack hair-covered bodies, but the feature that sets us furthest apart from other apes is a brain capable of language, art, science, and other trappings of civilisation. Now, two studies published online today in Cell1, 2 suggest that DNA duplication errors that happened millions of years ago might have had a pivotal role in the evolution of the complexity of the human brain. The duplications — which created new versions of a gene active in the brains of other mammals — may have endowed humans with brains that could create more neuronal connections, perhaps leading to greater computational power. The enzymes that copy DNA sometimes slip extra copies of a gene into a chromosome, and scientists estimate that such genetic replicas make up about 5% of the human genome.
In mice, the gene also increased the migration speed of neurons across the developing brain. Creativity and chronic disease Niccolo Paganini (1782-1840) Niccolo Paganini. The World's Greatest Violinist Niccolo Paganini was an Italian composer and virtuoso violinist who many still consider to be the greatest violinist that ever lived. His radical and brilliant innovations in violin technique are still heralded to this day; and his 24 Caprices are considered some of the most difficult music ever composed - only a handful of violinists at any period of time ever reach the heights of technique and musical ability required to play them. But although Paganini displayed a fearsome level of virtuosity that surpassed everyone else's, he didn't restrict himself to running fast scales and sweeping wide-interval arpeggios constantly. He also played the most tender and the most lyrical passages that charmed audiences so much they would openly weep and even swoon upon hearing him.
Violin Played by Niccolo' Paganini Exhibited in Palazzo Doria Tursi, Genova Italy In 1828, Paganini went on a tour of Europe that lasted for six and a half straight years. By Jason Earls. Paganini, How The Great Violinist Was Helped By A Rare Medical Condition « In Mozart's Footsteps – Uncommon Musical Travel. Paganini was one of the world’s great virtuoso violinists. But what is especially fascinating is that part of Paganini’s great success came as a result of a rare physical ailment. Niccolò Paganini was born in 1782 in Genoa, Italy. His father taught him mandolin at age five and violin two years later. Like many child prodigies, the boy’s musical talents were quickly recognized, and he began the serious study of the violin with a number of skilled teachers. By the time Paganini was eighteen he was well known around Genoa and Parma, and a decade or so later, the violinist had made a name for himself throughout Europe.
Pushing the Limits of the Violin In his relatively short life, Paganini dramatically increased the technical possibilities of the violin. But why could Paganini do these miraculous feats on the violin? Paganini’s Hands Marfan syndrome is a genetic disorder changes a person’s connective tissue, often making them unusually tall with lengthened limbs and long, thin fingers. How genetically modified crops are helping poor farmers in India. There's a much broader environmental concern than pests rapidly evolving resistance (even though that in itself is pretty fucking huge, the implications of which no one really knows).
With these monospeciated, transgenic, chemical fertilizer heavy, one-size-fits all practices, you also have to take into account - the decrease in crucial soil bacteria, reduction of nitrogenase enzymes (to help fix nitrogen), indiscriminate destruction of other soil-building/sustaining organisms and other micro-organisms (like fungi/mycorhizza), and the overall decimation of biomass. In other words, they're destroying not only biodiversity, but the soil itself. And the more chemical fertilizers they pump into the soil, the more they damage it, with their solution to pump even more fertilizers into the soil, which results in an ever intensifying self-feedback loop that will eventually collapse and create "dead" soils (and plenty of crop failures along the way). Researchers sequence fragments of the oldest human genome on Earth.
It's an interesting study, but it seems like the results could be misinterpreted in ways to fuel nationalist and ethnic furor. It's true that Spain has an incredibly rich history of invasion and migration, and therefore the genetic legacy of its inhabitants must therefore be equally layered and variable. But in this case, the geneticists studied only two individuals coming from a geographically distinct region of the far northwest of Spain. Given that the geology and climate of the Cantabrian Mountains is quite different from the rest of Spain (they are wetter, higher, greener, etc. than the arid plateaus and Mediterranean biomes of the rest of the peninsula).
It's quite easy to imagine that the individuals examined in this study were part of a population distinct from the rest of the peninsula, having migrated from elsewhere to an environment far more similar to the rest of Northern Europe than the rest of Spain.

iGEM, or How to Build a Biological Organism in a Single Summer. Tests of Parents Are Used to Map Genes of a Fetus. The accomplishment heralds an era in which parents might find it easier to know the complete DNA blueprint of a child months before it is born. That would allow thousands of genetic diseases to be detected prenatally. But the ability to know so much about an unborn child is likely to raise serious ethical considerations as well.
It could increase abortions for reasons that have little to do with medical issues and more to do with parental preferences for traits in children. “It’s an extraordinary piece of technology, really quite remarkable,” said Peter Benn, professor of and developmental biology at the University of Connecticut, who was not involved in the work. “What I see in this paper is a glance into the future.” The paper, published Wednesday in the journal Science Translational Medicine, was written by genome scientists at the . The process is not practical, affordable or accurate enough for use now, experts said. But Dr. Dr. Ethical questions emerge after baby’s genome sequenced while still in the womb. Transgenic sneaker company grows custom designs on genetically engineered stingrays.
Wait. Do you smell smoke? Oh yeah! It's the liars with their pants on fire! I just visited Rayfish's website and checked out their designs and... Holy hell, do they actually think people will believe this is legit? Yeah, you don't need to be a goddamn biologist (or a shoemaker) to understand that there's NO WAY you're gonna breed rayfish with patterns and colors like that on 'em and get those patterns onto shoes like that. But more shocking than the lie that they're trying to sell off as the truth is the actual business idea. Yeah, control the very existence of a living creature, then have it killed, and its death turned into a product that you can own.
