Treatment appropriate for some patients who are not good surgical candidates
A minimally invasive, experimental treatment is proving successful in removing small kidney tumors from appropriate patients, report researchers from Massachusetts General Hospital (MGH). In a study in the February 2003 issue of Radiology, the MGH team describes how a technique called radiofrequency ablation (RFA) destroyed all renal cell carcinoma (RCC) tumors less than 3 cm in size and some larger tumors, depending on their location. The most common form of kidney cancer, RCC will be diagnosed in almost 32,000 Americans this year and is most frequently treated with surgical removal through either an open or laparoscopic procedure.
"Were very pleased with the success weve had, particularly treating small tumors and those on the outside of the kidney," says Debra Gervais, MD, of the Abdominal Imaging and Interventional Radiology Service in the MGH Department of Radiology, the papers first author. "We now have an another year of experience beyond what is reported in this paper - more than 30 additional patients - with similar results."

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...
