Nanoscale composites improve MRI: Rice, Methodist researchers merge magnetic particles to detect, fight disease

Submicroscopic particles that contain even smaller particles of iron oxide could make magnetic resonance imaging (MRI) a far more powerful tool to detect and fight disease.

A virus reveals the physics of nanopores

Nanopores could provide a new way to sequence DNA quickly, but the physics involved isn't well understood. That's partly because of the complexities involved in studying the random, squiggly form DNA takes in solution. Researchers from Brown have simplified matters by using a stiff, rod-like virus instead of DNA to experiment with nanopores. Their research has uncovered previously unknown dynamics in polymer-nanopore interactions.

A better way to study what actually happens at the nanopore
A computer simulation depicts an fd virus translocating through a nanopore. Unlike DNA, which tangles up in solution, the fd remains stiff and straight, allowing researchers to study the physics of translocation through nanopores.

New computer program aims to teach itself everything about anything

In today's digitally driven world, access to information appears limitless. But when you have something specific in mind that you don't know, like the name of that niche kitchen tool you saw at a friend's house, it can be surprisingly hard to sift through the volume of information online and know how to search for it. Or, the opposite problem can occur - we can look up anything on the Internet, but how can we be sure we are finding everything about the topic without spending hours in front of the computer?

Some of the many variations the new program has learned for three different concepts.

Technology using microwave heating may impact electronics manufacture

Engineers at Oregon State University have successfully shown that a continuous flow reactor can produce high-quality nanoparticles by using microwave-assisted heating - essentially the same forces that heat up leftover food with such efficiency.
