First Human Embryos Edited In US (technologyreview.com)
randomErr shares a report from MIT Technology Review: The first known attempt at creating genetically modified human embryos in the United States has been carried out by a team of researchers in Portland, Oregon, MIT Technology Review has learned. The effort, led by Shoukhrat Mitalipov of Oregon Health and Science University, involved changing the DNA of a large number of one-cell embryos with the gene-editing technique CRISPR. Until now, American scientists have watched as scientists elsewhere were first to explore the controversial practice. To date, three previous reports of editing human embryos were all published by scientists in China. Now Mitalipov is believed to have broken new ground both in the number of embryos experimented upon and by demonstrating that it is possible to safely and efficiently correct defective genes that cause inherited diseases. In altering the DNA code of human embryos, the objective of scientists is to show that they can eradicate or correct genes that cause inherited disease, like the blood condition beta-thalassemia. The process is termed "germline engineering" because any genetically modified child would then pass the changes on to subsequent generations via their own germ cells -- the egg and sperm. Reached by Skype, Mitalipov declined to comment on the results, which he said are pending publication. But other scientists confirmed the editing of embryos using CRISPR. -
First Complete Lizard Genome Sequenced
iamrmani writes with an article in the International Business Times about the recent gene sequencing of a lizard. From the article: "Researchers have managed to sequence the genes of the green anole lizard, which is the first non-bird species of reptile to have its genome sequenced and assembled. The findings, which researchers have obtained after assembling and analyzing more than 20 mammalian genomes, may go a long way in understanding the evolution of animals and humans."
