The Protein Structure Initiative (PSI), a national program aimed at determining the three-dimensional shapes of a wide range of proteins, has now determined more than 1,000 different structures. These structures will shed light on how proteins function in many life processes and could lead to targets for the development of new medicines.

The PSI is a 10-year, approximately $600 million project funded largely by the National Institute of General Medical Sciences (NIGMS), part of the National Institutes of Health. The first half of this project—a pilot phase that started in 2000—has centered on developing new tools and processes that enable researchers to quickly, cheaply, and reliably determine the shapes of many proteins found in nature.
"One thousand protein structures is a significant milestone for the PSI, and it shows an impressive return on the investment in the technology and methods for rapid structure determination," said Jeremy M. Berg, Ph.D., director of NIGMS. "These structures are interesting in their own right and provide the basis for modeling many important proteins."

The pilot phase of the PSI will end in mid-2005. Centers for the second phase will be announced in July 2005.
In addition to NIGMS, the PSI currently receives funding from the National Institute of Allergy and Infectious Diseases, a component of the National Institutes of Health.

NIGMS is one of the 27 components of NIH, the premier federal agency for biomedical research. The NIGMS mission is to support basic biomedical research that lays the foundation for advances in disease diagnosis, treatment and prevention.

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...
