Scientists Discover Quadruple Helix: Four Strand DNA In Human Cells. The human race knows very little of itself, almost like a race with amnesia. As we continue to move forward through time, new discoveries are made that make old theories obsolete and false. It’s a good lesson that shows us how we can attach ourselves to “truths” and believe them whole-heartedly, often forgetting that truth is constantly changing and new paradigms of perception always lurk around the corner. Decades after scientists described our “chemical code” of life using the double helix DNA, researchers have discovered four-stranded DNA within human cells. The structures are called G-quadruplexes, because they form in regions of DNA that are full of guanine, one of the DNA molecule’s four building blocks.
The others are adenine, cytosine and thymine. The discovery was published online in Nature Chemistry, and you can take a look at it here. We are seeing links between trapping the G-quadruplexes with molecules and the ability to stop cells dividing, which is hugely exciting. Organ, tissue replacement could end aging by mid-2020s - ImmortalLife.net. Posted: Tue, May 14, 2013 | By: Dick Pelletier As we trek through the next decade, older citizens might look in the mirror and wonder, “Who is that gorgeous creature?” Their reflection would reveal a body filled with enthusiasm, sporting a dazzling smile, wrinkle-free skin, perfect vision, natural hair color, real teeth, and an amazing sharp mind and memory.
Welcome to the incredible world of innovative anti-aging healthcare, which growing numbers of future followers believe will become widely available and affordable as we move into the years ahead. This essay first appeared in Dick Pelletier’s Positive Futurist blog, HERE With new clinical trials popping up almost daily, experts predict that by early-to-mid 2020s, doctors will use stem cells loaded with non-degrading telomeres, and low-cost 3D bioprinters to replace aging skin and strengthen frail bones and muscles. Some say that Centagen’s work might one day be considered the ‘holy grail’ of stem cell research. Científicos japoneses consiguen hacer transparentes partes del cuerpo. Los científicos hicieron su descubrimiento mediante la experimentación con soluciones especiales que cambian el índice de refracción de diferentes fragmentos del cuerpo.
El aumento de este índice hace 'invisibles' las moléculas de grasa y azúcar en los tejidos del organismo. Los experimentos han demostrado que la solución que tiene un índice de refracción ideal es la de la fructosa, que consigue el índice ideal a una temperatura de 37 grados y así no viola la estructura y la forma de los órganos. Los investigadores probaron los efectos de la solución en varios embriones de ratones, así como en los cerebros de roedores jóvenes y adultos. Durante tres días las muestras de los órganos estuvieron remojándose en la solución hasta que finalmente se convirtieron en completamente transparentes.
El análisis mostró que ni la estructura celular ni la forma de las muestras resultaron dañadas. Talking Robot Mouth Mimics Human Speech #DigInfo. World’s First GM Babies Born. The world’s first geneticallymodified humans have been created, it was revealed last night. The disclosure that 30 healthy babies were born after a series of experiments in the United States provoked another furious debate about ethics. So far, two of the babies have been tested and have been found to contain genes from three ‘parents’. Fifteen of the children were born in the past three years as a result of one experimental programme at the Institute for Reproductive Medicine and Science of St Barnabas in New Jersey. The babies were born to women who had problems conceiving. Extra genes from a female donor were inserted into their eggs before they were fertilised in an attempt to enable them to conceive.
Genetic fingerprint tests on two one-year- old children confirm that they have inherited DNA from three adults –two women and one man. Some experts severely criticised the experiments. ‘It is a further and very worrying step down the wrong road for humanity.’
