    Description: Doping dependences of the resistivity and the Hall coefficient are presented for neodymium-doped lanthanum strontium cuprate (La(1.4-x)Nd(0.6)Sr(x)CuO(4)) in the static spin-charge stripe ordered phase. For doping concentration x 〈/= 1/8, a rapid decrease in the magnitude of the Hall coefficient at low temperatures provides evidence for one-dimensional charge transport, whereas for x 〉 1/8, the Hall coefficient remains relatively large in the ordered phase. The results indicate a crossover from one- to two-dimensional charge transport taking place at x = 1/8.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Noda -- Eisaki -- Uchida -- New York, N.Y. -- Science. 1999 Oct 8;286(5438):265-268.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Superconductivity, The University of Tokyo, Tokyo 113-8656, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10514365" target="_blank"〉PubMed〈/a〉

    Description: It was recently demonstrated that peptide bond formation can occur using an Escherichia coli naked 23S ribosomal RNA without any of the ribosomal proteins. Here, the six domains of the 23S ribosomal RNA were individually synthesized and shown to be capable, when complexed together, of stimulating the reaction. Omission and addition experiments indicated that the activity could be reconstituted solely by domain V at a concentration 10 times higher than that of the intact 23S ribosomal RNA, whereas domain VI could enhance the activity in trans. These findings suggest that fragments of an RNA molecule have the ability to associate into a functional whole.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nitta, I -- Kamada, Y -- Noda, H -- Ueda, T -- Watanabe, K -- New York, N.Y. -- Science. 1998 Jul 31;281(5377):666-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Biotechnology, Graduate School of Engineering, University of Tokyo, 7-3-1 Hongo, Bunkyo-ku, Tokyo 113-8656, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9685252" target="_blank"〉PubMed〈/a〉

    Description: Angle-resolved photoemission spectroscopy was carried out on (La(1.28)Nd(0.6) Sr(0.12))CuO(4), a model system of the charge- and spin-ordered state, or stripe phase. The electronic structure contains characteristic features consistent with other cuprates, such as the flat band at low energy near the Brillouin zone face. However, the low-energy excitation near the expected d-wave node region is strongly suppressed. The frequency-integrated spectral weight is confined inside one-dimensional segments in the momentum space (defined by horizontal momenta &cjs3539;k(x)&cjs3539; = pi/4 and vertical momenta &cjs3539;k(y)&cjs3539; = pi/4), deviating strongly from the more rounded Fermi surface expected from band calculations. This departure from the two-dimensional Fermi surface persists to a very high energy scale. These results provide important information for establishing a theory to understand the charge and spin ordering in cuprates and their relation with high-temperature superconductivity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhou -- Bogdanov -- Kellar -- Noda -- Eisaki -- Uchida -- Hussain -- Shen -- New York, N.Y. -- Science. 1999 Oct 8;286(5438):268-272.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physics, Applied Physics and Stanford Synchrotron Radiation Laboratory, Stanford University, Stanford, CA 94305, USA.

    Description: DFN3, an X chromosome-linked nonsyndromic mixed deafness, is caused by mutations in the BRN-4 gene, which encodes a POU transcription factor. Brn-4-deficient mice were created and found to exhibit profound deafness. No gross morphological changes were observed in the conductive ossicles or cochlea, although there was a dramatic reduction in endocochlear potential. Electron microscopy revealed severe ultrastructural alterations in cochlear spiral ligament fibrocytes. The findings suggest that these fibrocytes, which are mesenchymal in origin and for which a role in potassium ion homeostasis has been postulated, may play a critical role in auditory function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Minowa, O -- Ikeda, K -- Sugitani, Y -- Oshima, T -- Nakai, S -- Katori, Y -- Suzuki, M -- Furukawa, M -- Kawase, T -- Zheng, Y -- Ogura, M -- Asada, Y -- Watanabe, K -- Yamanaka, H -- Gotoh, S -- Nishi-Takeshima, M -- Sugimoto, T -- Kikuchi, T -- Takasaka, T -- Noda, T -- New York, N.Y. -- Science. 1999 Aug 27;285(5432):1408-11.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, The Cancer Institute, Japanese Foundation for Cancer Research, 1-37-1 Kami-ikebukuro, Toshima-ku, Tokyo 170-8455, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10464101" target="_blank"〉PubMed〈/a〉

    Description: Familial adenomatous polyposis coli (FAP) is a disease characterized by the development of multiple colorectal adenomas, and affected individuals carry germline mutations in the APC gene. With the use of a conditional gene targeting system, a mouse model of FAP was created that circumvents the embryonic lethality of Apc deficiency and directs Apc inactivation specifically to the colorectal epithelium. loxP sites were inserted into the introns around Apc exon 14, and the resultant mutant allele (Apc580S) was introduced into the mouse germline. Mice homozygous for Apc580S were normal; however, upon infection of the colorectal region with an adenovirus encoding the Cre recombinase, the mice developed adenomas within 4 weeks. The adenomas showed deletion of Apc exon 14, indicating that the loss of Apc function was caused by Cre-loxP-mediated recombination.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shibata, H -- Toyama, K -- Shioya, H -- Ito, M -- Hirota, M -- Hasegawa, S -- Matsumoto, H -- Takano, H -- Akiyama, T -- Toyoshima, K -- Kanamaru, R -- Kanegae, Y -- Saito, I -- Nakamura, Y -- Shiba, K -- Noda, T -- New York, N.Y. -- Science. 1997 Oct 3;278(5335):120-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, Cancer Institute, Toshima-ku, Tokyo 170, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9311916" target="_blank"〉PubMed〈/a〉

    Description: Shorter-wavelength surface-emitting laser sources are important for a variety of fields, including photonics, information processing, and biology. We report on the creation of a current-driven blue-violet photonic-crystal surface-emitting laser. We have developed a fabrication method, named "air holes retained over growth," in order to construct a two-dimensional gallium nitride (GaN)/air photonic-crystal structure. The resulting periodic structure has a photonic-crystal band-edge effect sufficient for the successful operation of a current-injection surface-emitting laser. This represents an important step in the development of laser sources that could be focused to a size much less than the wavelength and be integrated two-dimensionally at such short wavelengths.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Matsubara, Hideki -- Yoshimoto, Susumu -- Saito, Hirohisa -- Jianglin, Yue -- Tanaka, Yoshinori -- Noda, Susumu -- New York, N.Y. -- Science. 2008 Jan 25;319(5862):445-7.

    Description: Termites harbor diverse symbiotic gut microorganisms, the majority of which are as yet uncultivable and their interrelationships unclear. Here, we present the complete genome sequence of the uncultured Bacteroidales endosymbiont of the cellulolytic protist Pseudotrichonympha grassii, which accounts for 70% of the bacterial cells in the gut of the termite Coptotermes formosanus. Functional annotation of the chromosome (1,114,206 base pairs) unveiled its ability to fix dinitrogen and recycle putative host nitrogen wastes for biosynthesis of diverse amino acids and cofactors, and import glucose and xylose as energy and carbon sources. Thus, nitrogen fixation and cellulolysis are coupled within the protist's cells. This highly evolved symbiotic system probably underlies the ability of the worldwide pest termites Coptotermes to use wood as their sole food.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hongoh, Yuichi -- Sharma, Vineet K -- Prakash, Tulika -- Noda, Satoko -- Toh, Hidehiro -- Taylor, Todd D -- Kudo, Toshiaki -- Sakaki, Yoshiyuki -- Toyoda, Atsushi -- Hattori, Masahira -- Ohkuma, Moriya -- New York, N.Y. -- Science. 2008 Nov 14;322(5904):1108-9. doi: 10.1126/science.1165578.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Ecomolecular Biorecycling Science Research Team, RIKEN Advanced Science Institute, Saitama 351-0198, Japan. yhongo@riken.jp〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19008447" target="_blank"〉PubMed〈/a〉

    Description: The farside gravity field of the Moon is improved from the tracking data of the Selenological and Engineering Explorer (SELENE) via a relay subsatellite. The new gravity field model reveals that the farside has negative anomaly rings unlike positive anomalies on the nearside. Several basins have large central gravity highs, likely due to super-isostatic, dynamic uplift of the mantle. Other basins with highs are associated with mare fill, implying basalt eruption facilitated by developed faults. Basin topography and mantle uplift on the farside are supported by a rigid lithosphere, whereas basins on the nearside deformed substantially with eruption. Variable styles of compensation on the near- and farsides suggest that reheating and weakening of the lithosphere on the nearside was more extensive than previously considered.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Namiki, Noriyuki -- Iwata, Takahiro -- Matsumoto, Koji -- Hanada, Hideo -- Noda, Hirotomo -- Goossens, Sander -- Ogawa, Mina -- Kawano, Nobuyuki -- Asari, Kazuyoshi -- Tsuruta, Sei-Itsu -- Ishihara, Yoshiaki -- Liu, Qinghui -- Kikuchi, Fuyuhiko -- Ishikawa, Toshiaki -- Sasaki, Sho -- Aoshima, Chiaki -- Kurosawa, Kosuke -- Sugita, Seiji -- Takano, Tadashi -- New York, N.Y. -- Science. 2009 Feb 13;323(5916):900-5. doi: 10.1126/science.1168029.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Kyushu University, 6-10-1 Hakozaki, Higashi-ku, Fukuoka 812-8581, Japan. nori@geo.kyushu-u.ac.jp〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19213911" target="_blank"〉PubMed〈/a〉
