A team of radiologists and orthopedic specialists at Johns Hopkins Medicine has successfully used heat generated by electrode-tipped probes to destroy painful, benign bone tumors in eight of nine patients in a clinical study.
The results of the study, published in the March issue of the Journal of Vascular Interventional Radiology, suggests a need for further research to confirm the effectiveness of percutaneous radiofrequency for treating osteoid osteomas.
In the study, all eight patients achieved complete pain relief after thin probes were inserted through the skin into the core of the bone tumor, and radiofrequency energy was used to produce enough heat to destroy the tumor at its biological core. Five patients underwent the procedure with guidance provided by a new type of fast CT scanner incorporating CT fluoroscopy at 13 frames a second in three places at once.

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...
