New research from North Carolina State University finds that gold nanoparticles with a slight positive charge work collectively to unravel DNA’s double helix. This finding has ramifications for gene therapy research and the emerging field of DNA-based electronics.

“We began this work with the goal of improving methods of packaging genetic material for use in gene therapy,” says Dr. Anatoli Melechko, an associate professor of materials science and engineering at NC State and co-author of a paper describing the research. Gene therapy is an approach for addressing certain medical conditions by modifying the DNA in relevant cells. (more…)

Researchers at Yale University have developed a novel nanoparticle with promising applications in gene therapy, a type of medical treatment that addresses the root causes of diseases now typically treated for symptoms.

The advance could lead to new therapies for many forms of cancer, including brain tumors, as well as for cystic fibrosis and Huntington’s Disease. (more…)

COLUMBUS, Ohio – A floating weed that clogs waterways around the world has at least one redeeming feature: It’s inspired a high-tech waterproof coating intended for boats and submarines.

The Brazilian fern Salvinia molesta has proliferated around the Americas and Australia in part because its surface is dotted with oddly shaped hairs that trap air, reduce friction, and help the plant stay afloat. (more…)
