Dale Greiner and colleagues at the University of Massachusetts have developed a protocol for achieving stem cell transplantation that is not limited by significant patient side-effects and may not necessarily require that donor blood, bone marrow or whole organs are a "match" with the recipient –- characteristics that make these new procedures highly attractive for development and use in clinical human transplantation.
Hematopoietic stem cells (HSCs) are parent cells in the bone marrow that give rise to blood cells. Allogeneic stem cell transplantation has great potential in the treatment of malignancy, genetic disorders, and in solid organ transplantation. However, the radiation or high doses of chemotherapy commonly used in the treatment of blood cancers to destroy abnormal HSCs--a process called myeloablation-- is very toxic.
Furthermore, even following this form of conditioning, many patients develop graft-versus-host disease (GVHD), where the host immune system launches an attack against the newly transplanted HSCs.

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...
