Genetics

Cheap, easy technique to snip DNA could revolutionize gene therapy
January 8, 2013

The bacterial enzyme Cas9 is the engine of RNA-programmed genome engineering in human cells (credit: Jennifer Doudna/UC Berkeley) A simple, precise, and inexpensive method for cutting DNA to insert genes into human cells could transform genetic medicine, making routine what now are expensive, complicated and rare procedures for replacing defective genes to fix genetic disease or even cure AIDS. Discovered last year, two new papers published last week in the journal Science Express … more…


Editing the genome with high precision
January 8, 2013

mit_editing_genome Researchers at MIT, the Broad Institute and Rockefeller University have developed a new technique for precisely altering the genomes of living cells by adding or deleting genes. The researchers say the technology could offer an easy-to-use, less-expensive way to engineer organisms that produce biofuels; to design animal models to study human disease; and  to develop … more…


How to sequence an entire genome from a single cell
January 8, 2013

genome The notion that police can identify a suspect based on the tiniest drop of blood or trace of tissue has long been a staple of TV dramas, but scientists at Harvard have now taken the idea a step further. Using just a single human cell, they can reproduce an individual’s entire genome. The researchers developed … more…
