Choosing the best chops, steaks or other fresh meat products is a tough job. Its a delicate balancing of leanness, juiciness, taste, marbling and more. Increasingly, meat processors use electronic devices and equipment---such as optical probes, ultrasonic sensors and digital cameras---to evaluate critical fat to meat ratios. In 2003, for instance, electronic devices determined pricing for more than 80 percent of the almost $7.5 billion worth of swine processed in the United States. Multiple devices, as well as different methods for evaluating results can, however, produce different data.
The National Institute of Standards and Technology (NIST) has joined meat industry counterparts, producers, device manufacturers, the United States Department of Agriculture (USDA) and ASTM International (formerly the American Society for Testing and Materials) to standardize the measuring process for pork, beef and, eventually, poultry.
In February, ASTM committees, representing all concerned parties, approved the first two of four draft standards to cover key aspects of the electronic methods used to determine the value of live animals, carcasses and individual cuts. The approved standards outline requirements for installation, operator training, operation, verification, inspection, maintenance, design and construction of devices or systems. The remaining two standards, expected to be approved in the spring of 2004, cover calibration, accuracy and standardized equations for pricing meat. The final standards are expected to be incorporated into new USDA regulations.

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...
