Breast cancer is the most common and the second-most fatal malignant tumour amongst women who live in industrialised countries. Moreover, when present in young women, it would appear that a genetic predisposition is involved. This predisposition can be due to a number of causes and, amongst the most common, lie the alterations in the gene suppressors of the tumours. The lack of efficiency in these genes may be due to the fact that they are altered (mutated), they are not expressed, or they do not function because their start-up system (methylation) is altered, or a fragment is missing (deletion).
Mutations of specific gene suppressors (Brca1, Bcra2, ATM; Che2...), which in principle might be thought to be of great use in the clinic, are much more frequent than previously thought and, moreover, difficult to detect in many occasions. This is why, in clinical applications, more general markers to help in the prognosis of early breast cancer development are sought. These markers would indicate, for example, which patients need chemotherapy and which do not.

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...
