Initial results of the nations largest clinical trial for depression have helped clinicians to track "real world" patients who became symptom-free and to identify those who were resistant to the initial treatment. Participants treated in both medical and specialty mental health care settings experienced a remission of symptoms in 12 to 14 weeks during well-monitored treatment with an antidepressant medication. The study, funded by the National Institutes of Healths (NIH) National Institute of Mental Health (NIMH), used flexible adjustment of dosages based on quick and easy-to-use clinician ratings of symptoms and patient self-ratings of side effects.
About a third of participants reached a remission or virtual absence of symptoms during the initial phase of the study, with an additional 10 to 15 percent experiencing some improvement. Subsequent phases of the trials will help determine successful treatments for the nearly two thirds of those patients who were identified as treatment-resistant to a first medication in phase one.
The trial, known as the STAR*D study -- Sequenced Treatment Alternatives to Relieve Depression -- included 2,876 participants and was conducted over six years at a cost of $35 million. (For more information on STAR*D, go to: http://www.clinicaltrials.gov/ct/show/NCT00021528?order=1).

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...
