Scientists have finished sequencing the first complete octopus genome, and it’s a big step toward unraveling many cephalopod mysteries, including the basis of their unusual intelligence and unmatched camouflage abilities. »
The fear of genetically-modified creatures escaping from the lab is the basis for a thousand sci-fi stories, but it’s also a legitimate concern. That’s why genetic engineers are inventing kill switches, or genetically-encoded suicide triggers, for GMOs they want to keep contained. Here’s how they work.
The Y chromosome, a chunk of genetic code that is unique to male mammals, isn’t just physically smaller than the X. It also contains far fewer genes. The X has more than 1000 genes, while the Y has fewer than 200 —and most of them don’t even work. Why do men have this odd, stunted chromosome in their genomes? »
Organoids are exactly what they sound like: simplified miniature organs. And now geneticists are growing them out of living cancer cells, creating tiny, living cancer tumors for study. It sounds terrifying, but it’s actually one possible way we’ll get personalized medicine to treat many kinds of cancer. »
Today, 23andMe announced what Forbes reports is only the first of ten deals with big biotech companies: Genentech will pay up to $60 million for access to 23andMe's data to study Parkinson's. You think 23andMe was about selling fun DNA spit tests for $99 a pop? Nope, it's been about selling your data all along. »
If—like most of us—your entire understanding of DNA and genetics can be traced back to CSI reruns, you’re probably under the impression that your genome is unique; that it defines you completely. But scientists increasingly believe that’s not that case. In fact, we need to start thinking about our genomes differently. »
Researchers at a hospital in Kansas have been using this machine to crank out entire genome sequences of just-born babies in two days—which could be fast enough to change treatment regimes and save their wonderful little lives. »
Today a group of medical researchers reported the discovery of something very intriguing in a type of pancreatic cancer called PanNET. Turns out PanNET is associated with mutations in two genes that help control a part of your DNA that determines whether you die. »
