Defects give the immune system the green light to attack the pancreas
Scientists at Joslin Diabetes Center have found genetic regions that, when defective, allow the immune system to attack the pancreas - the first in a series of mis-steps that lead to type 1 diabetes. Armed with these findings, published today, March 22, in the journal Immunity, the researchers are now trying to hone in on the exact genes involved, in mice and in human patients.
"The significance of this study is that we found the chromosomal regions involved and can now zero in on the precise genes," said Diane Mathis, Ph.D., the study’s principal investigator along with Christophe Benoist, M.D., Ph.D. They head the Section on Immunology and Immunogenetics at Joslin, and hold joint William T. Young Chairs in Diabetes Research. They are also Professors of Medicine at Harvard Medical School. The work was spearheaded by a group of Joslin fellows, hailing from across the globe: Silvia Zucchelli, Ph.D., who has now returned to Italy; Phil Holler, Ph.D., from the U.S.; and Tetsuya Yamagata, M.D., Ph.D, from Japan.

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...
