Nanotechnology innovation may revolutionize gene detection in a single cell

Scientists at Arizona State University's Biodesign Institute have developed the world’s first gene detection platform made up entirely from self-assembled DNA nanostructures. The results, appearing in the Jan. 11 issue of the journal Science, could have broad implications for gene chip technology and may also revolutionize the way in which gene expression is analyzed in a single cell.

   Paying close attention to how a canary learns a new song has helped scientists open a new avenue of research against Huntington's disease -- a fatal disorder for which there is currently no cure or even a treatment to slow the disease. Scientists used gene therapy to guide the development of endogenous stem cells in the brains of mice affected by a form of Huntington’s, generating new medium spiny neurons -- the cell lost in Huntington's disease.
