Virus Helps Shed New Light on Nanopores for DNA Sequencing

Nanopores may one day lead a revolution in DNA sequencing. By sliding DNA molecules one at a time through tiny holes in a thin membrane, it may be possible to decode long stretches of DNA at lightning speeds. Scientists, however, haven't quite figured out the physics of how polymer strands like DNA interact with nanopores. Now, with the help of a particular type of virus, researchers from Brown University have shed new light on this nanoscale physics.

Study Advances Use of Nanoparticles as Vehicles for Delivering Genes Across Cellular Membranes

Scientists seeking ways to engineer the assembly of tiny particles measuring just billionths of a meter have achieved a new first—the formation of a single layer of nanoparticles on a liquid surface where the properties of the layer can be easily switched. Understanding the assembly of such nanostructured thin films could lead to the design of new kinds of filters or membranes with a variable mechanical response for a wide range of applications.

Levels of a Tiny Molecule May Provide Marker for Depression

Levels of a small molecule found only in humans and in other primates are lower in the brains of depressed individuals, according to researchers at McGill University and the Douglas Institute. This discovery may hold a key to improving treatment options for those who suffer from depression.

NIST Develops DNA-Based Nanocomposite Biocoatings for Fire-Retarding Polyurethane Foam

What sounds like fixings for a wizard’s potion—a dash of clay, a dab of fiber from crab shells, and a dollop of DNA—actually are the ingredients of promising green fire retardants invented by researchers at the National Institute of Standards and Technology (NIST).
