St. Jude researchers say reprogrammed nucleus model could offer valuable clues to how certain influencing factors combine with DNA mutations to cause tumors
Nuclei removed from mouse brain tumor cells and transplanted into mouse eggs whose own nuclei have been removed, give rise to cloned embryos with normal tissues, even though the mutations causing the cancer are still present. This research, from scientists at St. Jude Childrens Research Hospital, appears in the June 1 issue of Cancer Research.
The finding demonstrates that the cancerous state can be reversed by reprogramming the genetic material underlying the cancer, according to James Morgan, Ph.D., a member of the St. Jude Department of Developmental Neurobiology, and lead author of the study. The findings also indicate that genetic mutations alone are not always sufficient to cause a cell to become cancerous.

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...
