New agricultural crops stand a better chance of helping to fill the worlds bread baskets, says a University of Maine economist, if plant breeders take farmers needs into account early in the crop development process. A new research report by Timothy J. Dalton, assistant professor in the Dept. of Resource Economics and Policy, is one of the first to demonstrate farmers preferences using a quantitative approach.
Daltons research could help agricultural research organizations work with farmers in developing countries to increase food production. His paper, A Hedonic Model of Rice Traits: Economic Values from Farmers in West Africa, won a second place award in the T.W. Schultz competition for the best contributed paper at the 25th International Conference of Agricultural Economists in Durban, South Africa in August. The paper will be published in the journal Agricultural Economics in 2004.
Dalton is also co-author with R. G. Guei of a book chapter, Ecological Diversity and Rice Varietal Improvement in West Africa, that was cited in a recent article on the Green Revolution in Science magazine.

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...
