Also helps some patients avoid hysterectomy
MRI-guided ultrasound therapy is an effective way to treat women with uterine fibroids, improving their quality of life and avoiding hysterectomy, a new study shows. The study reviewed the use of MRI and the ExAblate 2000, a device that was recently approved by the Food and Drug Administration.
About 25% of women have uterine fibroids with a substantial proportion of these experiencing symptoms, said Dr. Wladyslaw Gedroyc of St. Marys Hospital and the Imperial College School of Medicine in London. These symptoms include abdominal pain, bladder irritability and menstrual irregularities, he said. These patients are commonly treated with surgery. However, "our study of 109 patients found that combining MRI and ultrasound can be a viable alternative to a hysterectomy or myomectomy."

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...
