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.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
