Women whose breast cancer was detected by screening mammography had a significantly better prognosis than those whose cancer was found another way - even if the cancer had already spread to their lymph nodes, say researchers at The University of Texas M. D. Anderson Cancer Center who looked at outcomes from randomized screening studies of more than 150,000 women.
A likely reason for that finding is that mammography can detect tumors that are both slower growing and less biologically lethal than those found symptomatically, say the researchers, who published their findings in the Aug. 17 issue of the Journal of the National Cancer Institute.
The study is important because the survival benefit seen in this analysis is much greater than one would expect for screen-detected breast cancer, says the studys lead author Donald Berry, Ph.D., chair of the Department of Biostatistics and Applied Mathematics. Berry is well-known for his work in designing breast cancer clinical trials sponsored by the National Cancer Institute and for his research in evaluating the effects of screening mammography.

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...
