Phosphate bound to calcareous sediments hamper skeletal development of juvenile coral

Mariko Iijima
To test the hypothesis that terrestrial runoff affects the functions of calcareous sediments in coral reefs and hampers the development of corals, we analysed calcareous sediments with different levels of bound phosphate, collected from reef areas of Okinawajima, Japan. We confirmed that phosphate bound to calcareous sediments were readily released into ambient seawater, resulting in much higher concentrations of phosphorous in seawater from heavily polluted areas (4.3 to 19.0 µM as compared with < 0.096...

Automatic radioisotope manipulation for small amount of nuclear medicine using an EWOD device with a dimple structure

Katsuo Mogi, Hiroyuki Kimura, Yuto Kondo, Tomoya Inoue, Shungo Adachi & Tohru Natsume
Delicate animal experiments and microdose clinical trials using short-lived radioisotopes require rapid preparation with high accuracy and careful attention to safety within a limited timeframe. We have developed an open-style electrowetting on dielectric device containing dimple structures for the rapid preparation of radiolabelled reagents. The device was demonstrated by automatic preparation of a 99mTc-DTPA with high chelation efficiency (99.7 ± 0.13%). Additionally, we demonstrated the single photon emission computed tomography (SPECT)/Computed tomography (CT) imaging of...

Comprehensive comparative morphology and developmental staging of final instar larvae toward metamorphosis in the insect order Odonata

Genta Okude, Takema Fukatsu & Ryo Futahashi
The order Odonata (dragonflies and damselflies) is among the most ancestral groups of winged insects with drastic morphological changes upon metamorphosis, and thus important for understanding evo-devo aspects of insects. However, basic developmental descriptions of Odonata have been scarce. In an attempt to establish the foundation of developmental and experimental biology of Odonata, we present an unprecedentedly comprehensive survey of dragonflies and damselflies, in total 158 larvae representing 49 species and 14 families, wherein morphological...

Venus Climate Orbiter Akatsuki Cloud Motion Vector Data Set

Takeshi Horinouchi, Shin-ya Murakami, Kazunori Ogohara, Toru Kouyama & Masahiro Takagi
This dataset contains cloud motion vector data acquired by the automated cloud tracking from images of the UVI and IR2 instruments of the Venus Climate Orbiter (VCO, also known as PLANET-C and AKATSUKI) spacecraft. This dataset consists of NetCDF files. This dataset is produced from the longitude-latitude map datasets.

Insecticide resistance governed by gut symbiosis in a rice pest, Cletus punctiger, under laboratory conditions

Kota ISHIGAMI, Seonghan JANG, Hideomi ITOH & Yoshitomo KIKUCHI
Resistance to toxins in insects is generally thought of as their own genetic trait, but recent studies have revealed that gut microorganisms could mediate resistance by detoxifying phytotoxins and man-made insecticides. By laboratory experiments, we here discovered a striking example of gut symbiont-mediated insecticide resistance in a serious rice pest, Cletus punctiger. The rice bug horizontally acquired fenitrothion-degrading Burkholderia through oral infection and housed it in midgut crypts. Fenitrothion-degradation test revealed that the gut-colonizing Burkholderia...
