Virginia Tech scientists say that there has been a change in the status of the fungus causing Asian Soybean Rust but that the new information is still too preliminary for any action on the part of the Commonwealths soybean producers.
A single cluster of six urediniospores found at Virginia Techs Tidewater Agricultural Research and Extension Center in Suffolk was identified by morphological characteristics as matching the description of the fungus.
"The spores in question appear to resemble the causal agent of Asian Soybean Rust, Phakopsora pachyrhizi, said Erik Stromberg, interim head of the Department of Plant Pathology, Physiology and Weed Science in Virginia Techs College of Agriculture and Life Sciences. "But we can not be absolutely certain that they are. The weather conditions between Aug. 5 and 11, the time the sample was found, were extremely hot and dry and not conducive for promoting the infection process. Researchers found no indication of Asian Soybean Rust when they examined the adjacent sentinel plots and other nearby fields. At this time, no recommendation for fungicide is warranted in Virginia. It is highly unlikely that Asian Soybean Rust will be detected in any soybeans in Virginia for at least three weeks."

Sweet route to greater yields

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...
