We measured the transmittance of filters and the substitutes for direct observation of the sun, from 2009 to 2012. In this paper, we report the results of the measurements in detail. This paper gives fundamental data for observing solar eclipses safely.

May 21, 2012, solar eclipse was observed in Japan. This time, annular eclipse occurred over a wide range; i.e. the southern part of Kyushu, the southern part of Shikoku, the southern part of the Kinki, the southern part of the Chubu, such as the Kanto. Other regions became a partial solar eclipse. Approximately 83 million people are living in the path of annular phase, we were expected many people to observe the eclipse. Eclipse is a valuable opportunity to increase interest in science. On the other hand, when observing the sun, it runs a strong risk that leads to trouble in the eyes of people due to the strong sunlight. For example, in the case of the eclipse in Germany in 1912, solar eclipse retinopathy patients of 3,500 has occurred. We conducted our activities for many people to observe the eclipse safe. One of them is the spread of safe solar eclipse observation method, another is a research study of the safety of the solar eclipse glasses.In this paper, we report the transmittance measured in the various filters; solar viewing glass on the market, and their substitutes. These are valuable archival material related to solar observation glass for the solar eclipse in the future.

Here the three-dimensional (3-D) structure of TRET1, a novel trehalose transporter from an anhydrobiotic insect, Polypedilum vanderplanki, was predicted by homology modeling in which the 3-D structure (1SUK) of GLUT1, glucose transporter from human was selected as a template. It was found that TRET1 has 12 transmembrane (TM) helices with an inward-facing conformation. Next, to explore the dynamics of the protein, we performed molecular dynamics (MD) simulation for the protein embedded in a hydrated phospholipid bilayer. The result of principal component analysis indicated that the protein has a hinge-bending motion, that is, the helices on the intracellular side come close or draw apart together. This dynamics may be essential for substrate uptake. Furthermore, we performed docking simulation combined with binding energy calculation to investigate the substrate selectivity of TRET1. As a result, it was found that trehalose more strongly binds to TRET1 than its isomer, isotrehalose, consistent with available experimental data.
