Combining the tumor suppressing Rb2 gene with doses of gamma radiation speeds up the ability of tumor cells to die, according to a study by researchers at Temple Universitys College of Science and Technology.

Antonio Giordano, M.D., Ph.D., an internationally recognized researcher in the genetics of cancer and gene therapy, joined the faculty of Temple Universitys College of Science and Technology (CST) on March
The results of the study, "pRb2/p130 promotes radiation-induced death in glioblastoma cell line HJC12 by p73 upregulation and Bcl-2 downregulation," appear in the August 29 issue of Oncogene (Vol. 21, Issue 38).
In the study, which was started at Thomas Jefferson University and completed at Temples Sbarro Institute for Cancer Research and Molecular Medicine, the researchers found that when they treated tumor cells in which the Rb2 gene has been transplanted with gamma radiation, there was an increase of almost 50 percent in the ability of the cells to destroy themselves.

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...
