Study may open way to using bone marrow stem cells as diabetes treatment
In a finding that may open a new avenue to treating diabetes, researchers show that cells from the bone marrow give rise to insulin-producing cells in the pancreas of mice. These morphed cells actually produce the hormone insulin in response to glucose and display other characteristics demonstrating that they truly function as pancreas cells, according to a new study by researchers from NYU School of Medicine.
The study is published in the March 14 issue of the Journal of Clinical Investigation. The researchers caution that the findings cannot be applied to treating diabetics now, but may one day provide a means to produce unlimited quantities of functional insulin-producing cells culled from the bone marrow of diabetes patients. Since patients would produce their own cells for transplantation, it is possible that the cells would not be rejected by their immune system.

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...
