(Purdue University) Researchers have created magnetically responsive gold nanostars that may offer a new approach to biomedical imaging. The nanostars gyrate when exposed to a rotating magnetic field, and can scatter light to produce a pulsating or "twinkling" effect. This twinkling allows them to stand out more clearly from noisy backgrounds like those found in biological tissue.

The first implantable device that can monitor a tumor for weeks or months after a biopsy and track its growth and how it responds to treatment has been developed by MIT scientists. The cylindrical, 5-millimeter implant contains nagnetic nanoparticles coated with antibodies specific to the target molecules, which bind to the nanoparticles, causing them to clump together. The clumped nanoparticles produce a marked change in the MRI signal associated... More

A genetic mutation linked to psychosis and schizophrenia also influences creativity, a Semmelweis University researcher has found. He speculates that the mutation dampens a brain region that reins in mood and behavior, the prefrontal cortex. This change could unleash creative potential in some people and psychotic delusions in others.
