Into the CT scanner on a conveyor belt went little potted rice plants in an automated facility that could process 4,320 rice plants a day. The non-invasive CT energy analyzed tissues and matched their traits against a computer program to aid rice breeders in selecting plants with the best rice tillers. Tillers are specialized grain-bearing shoots of the plant that determine grain yield—and therefore are crucial to crop success.
Given that an estimated 3 billion people around the globe depend on one of the many species of rice for survival, demand pressure is high on rice breeders to maximize yield. Constructing large-scale, high-throughput automated industrial rice growing facilities helps. But one aspect of rice farming—tillering—is still done by hand. It is therefore vulnerable to human error that can undermine the success of a crop.
"In rice breeding, it is imperative that the traits of the tillers that result from hybridization or mutation are monitored and analyzed accurately," Dr. Liu explains. "This is true because with modern crop breeding methods using genetically modified organisms, it is possible to produce hundreds of new varieties daily. We need efficient techniques for screening the best plant material possible. Automating tillering by CT provided higher throughput, higher measurement accuracy and lower cost than other technologies previously used to measure the tillers on rice plants."
In the study, Dr. Liu collaborated with Wanneng Yang, Xiochun Xu, Lingfeng Duan, Qingming Luo, Shangbin Chen and Shaoqun Zeng at the Britton Chance Center for Biomedical Photonics, Wuhan National Laboratory for Optoelectronics-Huazhong University of Science and Technology.
The American Institute of Physics is an organization of 10 physical sciences societies representing more than 135,000 scientists, engineers, and educators and is one of the largest publishers of scientific information in physics. AIP also delivers valuable resources and expertise in education and student services, science communication, government relations, career services for science and engineering professionals, statistical research, industrial outreach, and the history of physics and other sciences. Offering publishing solutions for scientific societies and organizations in science and engineering, AIP pursues innovation in electronic publishing of scholarly journals. AIP publishes 13 journals (journals.aip.org), 2 magazines—including its flagship publication, Physics Today—and the AIP Conference Proceedings series. Scitation, AIP's online publishing platform, hosts 1.6 million articles from 190 scholarly journals, proceedings, and eBooks of learned society publishers. AIP also provides the international physical science community with UniPHY, the first literature-based social and professional networking site; it features pre-populated profiles of more than 300,000 scientists and enables collaboration among researchers worldwide.
REVIEW OF SCIENTIFIC INSTRUMENTS
Review of Scientific Instruments, published by the American Institute of Physics, is devoted to scientific instruments, apparatus, and techniques. Its contents include original and review articles on instruments in physics, chemistry, and the life sciences; and sections on new instruments and new materials. One volume is published annually. Conference proceedings are occasionally published and supplied in addition to the Journal's scheduled monthly issues. RSI publishes information on instruments, apparatus, techniques of experimental measurement, and related mathematical analysis. Since the use of instruments is not confined to the physical sciences, the journal welcomes contributions from any of the physical and biological sciences and from related cross-disciplinary areas of science and technology.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
