Uncharted area of umbilical cord offers hope
University of Toronto researchers have discovered an ample source of stem cells in an uncharted part of the umbilical cord, providing new hope for bone marrow transplants and tissue repair.
The study, published in the February issue of Stem Cells, outlines how researchers discovered that the jelly-like connective tissue surrounding the blood vessels of the human umbilical cord, the so-called "Whartons Jelly," is rich in mesenchymal progenitor cells – cells that generate bone, cartilage and other tissues – and can be harvested to generate an abundant supply in a short amount of time. This expandable source of progenitor cells could greatly improve bone marrow transplantation, a painful yet common procedure that currently has a 30 to 40 per cent success rate in treating disease.

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...
