Researchers at the San Francisco VA Medical Center (SFVAMC) have taken the first major step toward isolating adult stem cells from mouse skin, having developed a test that confirms the presence and number of stem cells in a given amount of tissue. Until now, such a technique has only existed for isolating adult stem cells found in blood.
"This assay has opened up a whole new avenue of research," said Ruby Ghadially, MD, SFVAMC staff physician and UCSF associate professor of dermatology. "If you can determine how many stem cells you have, then you can identify distinguishing characteristics that will allow you to isolate the cells. We could then potentially use these cells as effective carrier cells for gene therapy and, someday, use them to produce new stem cells for treating burns and wounds in the skin," Ghadially said.
The study was published online September 17 in the Proceedings of the National Academy of Sciencess online early edition, and will appear in the print version of the journal September 30.

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
