Study conducted in hamsters with same genetic defect as human muscular dystrophy shows great promise for treating adult heart failure
University of Pittsburgh investigators have for the first time used gene therapy to successfully treat heart failure and other degenerative muscle problems in an animal model that is genetically susceptible to a human muscular dystrophy. Reporting in the Oct. 25 edition of the journal Circulation, the authors say that this is the first successful attempt to deliver a therapeutic gene throughout the body.
"Previous attempts at systemic gene therapy for muscle have not been very effective because blood vessel capillaries act much like a mosquito net, blocking the gene drugs from reaching the muscle cells. Fortunately, we found a virus that is just small and sneaky enough to get through this net and deliver the therapeutic gene to both skeletal and cardiac muscle cells," said lead author, Xiao Xiao, Ph.D., associate professor of orthopaedic surgery at the University of Pittsburgh School of Medicine.

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...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
