Continued studies may result in newer, more effective breast cancer detection methods
Researchers at Oregon Health & Science Universitys Advanced Imaging Research Center (AIRC) are developing a new imaging method that may provide a clearer diagnosis of breast cancer. The research is published in the latest issue of the journal Magnetic Resonance in Medicine. AIRC Director Charles Springer, Ph.D., is senior author, and AIRC Manager, Xin Li, Ph.D., is first author of the new paper, along with William Rooney, Ph.D., AIRC faculty. Professor Springer also holds appointments in OHSUs Cancer Institute and Department of Biomedical Engineering.
"This technique involves a new method for interpreting information gathered through MRI," explained Springer. "The technique involves recognizing that certain properties of MRI signals can change during the examination, much like the changing of a cameras shutter speed. On a camera, a fast shutter speed can make a speeding car look as if it is standing still. A slower shutter speed may result in a photo showing the car blurring past the camera. This principle, when correctly applied to MRI imaging, can provide more accurate information. In the case of MRI, the blurring is not of the actual image, but of the time courses of the MRI signals."

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
