University of Toronto researchers have identified individual cells in the adult mouse pancreas capable of generating insulin-producing beta cells.
Their research, published Aug. 22 in the online edition of Nature Biotechnology, offers hope for the millions of diabetics worldwide who take insulin injections to compensate for defective pancreatic islets. Healthy islets, made up largely of beta cells, release insulin to help regulate the bodys blood sugar levels.
"People have been intensely searching for pancreatic stem cells for a while now, and so our discovery of precursor cells within the adult pancreas that are capable of making new pancreatic cells is very exciting," says Simon Smukler, a PhD candidate in U of Ts Department of Medical Genetics and Microbiology, who was one of the lead researchers. He conducted the study along with U of T MD/PhD candidate Raewyn Seaberg and their supervisor, Professor Derek van der Kooy.

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...
