SCIENCE: Storing Data in DNA

Government intelligence agencies have a plan to build computers that store information inside DNA and other organic molecules. Intelligence Advanced Research Projects Activity (IARPA), a group within the Office of the Director of National Intelligence that develops technologies for U.S. intelligence services, announced plans to develop “tabletop”-sized machines that can store and retrieve data from large batches of polymers — a term that refers to a wide variety of long, stringlike molecules. Polymers can store data in the sequence of individual atoms or groups of atoms. The project, which was reported by Nextgov, is an attempt to solve a basic … Read more

Science: De-Extincting the Wooly Mammoth

Did we learn nothing from “Jurassic Park?” A Harvard University scientist told The Guardian this week that his team is only two years from resurrecting some traits of the woolly mammoth, which went extinct during the last ice age. The goal is to create an embryo that’s a hybrid of the woolly mammoth and its closest living relative, the Asian elephant. “Our aim is to produce a hybrid elephant-mammoth embryo,” researcher George Church told The Guardian. “Actually, it would be more like an elephant with a number of mammoth traits.” Church explained to HuffPost last year that the process involves … Read more

Science Trying to Answer Why People Are Trans

Why are girls born as girls, and boys as boys? What about an individual who is biologically female but feels or sees oneself as male, or the other way around? Dr. Qazi Rahman who is a lead investigator into LGBT mental health at King’s College London revealed that science still can’t give a complete answer to those questions. ‘This is the key question at the moment,’ the scientist told The Guardian. ‘We know much more about how nature shapes sexual orientation, and my view of the science is that nurture does very little, if any, shaping of sexual orientation. We … Read more

For Writers: Storing Info in DNA

DNA Storage

Today’s writer topic comes from QSFer Freddy MacKay: Freddy flagged this article for us: http://m.phys.org/news/2016-04-team-digital-images-dnaand-perfectly.html All the movies, images, emails and other digital data from more than 600 basic smartphones (10,000 gigabytes) can be stored in the faint pink smear of DNA at the end of this test tube. Technology companies routinely build sprawling data centers to store all the baby pictures, financial transactions, funny cat videos and email messages its users hoard. But a new technique developed by University of Washington and Microsoft researchers could shrink the space needed to store digital data that today would fill a Walmart … Read more

News: Did Scientists Just Discover Evidence That ‘Gay Genes’ Exist?

by
DNA

Scientists may have found genetic indicators of whether someone has same or opposite-sex attraction. The link was discovered when scientists compared the DNA of 47 sets of male twins. The pairs included some where the two twins had a different sexual orientation. Looking at the molecular data from nine genome sites, researchers could guess whether a twin pair was straight or gay with up to 70% accuracy. Lead researcher Dr Tuck Ngun, from the University of California at Los Angeles, said: “To our knowledge, this is the first example of a predictive model for sexual orientation based on molecular markers.” … Read more
