Researchers at Duke University Medical Center have developed a new breast scanner that is designed to detect subtle changes in breast cells before a lump can be felt by hand or seen with X-ray mammography.

Such early detection should enable doctors to more successfully treat breast cancer before it has formed a tumor or spread to lymph nodes, said Martin Tornai, Ph.D., associate professor of radiology and biomedical engineering at Duke and developer of the device. The new camera has undergone extensive testing in artificial breasts and will begin testing in women this spring.
The camera uses nuclear medicine to pick up chemical changes to breast cells that signal the cells are becoming malignant, said Tornai. The camera should be particularly useful for detecting tumors in large or dense breasts, which are difficult to image using traditional mammography because X-rays often cannot penetrate them. Moreover, the geometry of the new device allows for imaging small breasts and the nearby chest wall. It can even image the axillary lymph nodes to look for evidence of metastasis -- which traditional mammography cannot do. The new device works without any breast compression, and women may not be required to remove their bras.

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...
