    Description: The fly Drosophila melanogaster is one of the most intensively studied organisms in biology and serves as a model system for the investigation of many developmental and cellular processes common to higher eukaryotes, including humans. We have determined the nucleotide sequence of nearly all of the approximately 120-megabase euchromatic portion of the Drosophila genome using a whole-genome shotgun sequencing strategy supported by extensive clone-based sequence and a high-quality bacterial artificial chromosome physical map. Efforts are under way to close the remaining gaps; however, the sequence is of sufficient accuracy and contiguity to be declared substantially complete and to support an initial analysis of genome structure and preliminary gene annotation and interpretation. The genome encodes approximately 13,600 genes, somewhat fewer than the smaller Caenorhabditis elegans genome, but with comparable functional diversity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Adams, M D -- Celniker, S E -- Holt, R A -- Evans, C A -- Gocayne, J D -- Amanatides, P G -- Scherer, S E -- Li, P W -- Hoskins, R A -- Galle, R F -- George, R A -- Lewis, S E -- Richards, S -- Ashburner, M -- Henderson, S N -- Sutton, G G -- Wortman, J R -- Yandell, M D -- Zhang, Q -- Chen, L X -- Brandon, R C -- Rogers, Y H -- Blazej, R G -- Champe, M -- Pfeiffer, B D -- Wan, K H -- Doyle, C -- Baxter, E G -- Helt, G -- Nelson, C R -- Gabor, G L -- Abril, J F -- Agbayani, A -- An, H J -- Andrews-Pfannkoch, C -- Baldwin, D -- Ballew, R M -- Basu, A -- Baxendale, J -- Bayraktaroglu, L -- Beasley, E M -- Beeson, K Y -- Benos, P V -- Berman, B P -- Bhandari, D -- Bolshakov, S -- Borkova, D -- Botchan, M R -- Bouck, J -- Brokstein, P -- Brottier, P -- Burtis, K C -- Busam, D A -- Butler, H -- Cadieu, E -- Center, A -- Chandra, I -- Cherry, J M -- Cawley, S -- Dahlke, C -- Davenport, L B -- Davies, P -- de Pablos, B -- Delcher, A -- Deng, Z -- Mays, A D -- Dew, I -- Dietz, S M -- Dodson, K -- Doup, L E -- Downes, M -- Dugan-Rocha, S -- Dunkov, B C -- Dunn, P -- Durbin, K J -- Evangelista, C C -- Ferraz, C -- Ferriera, S -- Fleischmann, W -- Fosler, C -- Gabrielian, A E -- Garg, N S -- Gelbart, W M -- Glasser, K -- Glodek, A -- Gong, F -- Gorrell, J H -- Gu, Z -- Guan, P -- Harris, M -- Harris, N L -- Harvey, D -- Heiman, T J -- Hernandez, J R -- Houck, J -- Hostin, D -- Houston, K A -- Howland, T J -- Wei, M H -- Ibegwam, C -- Jalali, M -- Kalush, F -- Karpen, G H -- Ke, Z -- Kennison, J A -- Ketchum, K A -- Kimmel, B E -- Kodira, C D -- Kraft, C -- Kravitz, S -- Kulp, D -- Lai, Z -- Lasko, P -- Lei, Y -- Levitsky, A A -- Li, J -- Li, Z -- Liang, Y -- Lin, X -- Liu, X -- Mattei, B -- McIntosh, T C -- McLeod, M P -- McPherson, D -- Merkulov, G -- Milshina, N V -- Mobarry, C -- Morris, J -- Moshrefi, A -- Mount, S M -- Moy, M -- Murphy, B -- Murphy, L -- Muzny, D M -- Nelson, D L -- Nelson, D R -- Nelson, K A -- Nixon, K -- Nusskern, D R -- Pacleb, J M -- Palazzolo, M -- Pittman, G S -- Pan, S -- Pollard, J -- Puri, V -- Reese, M G -- Reinert, K -- Remington, K -- Saunders, R D -- Scheeler, F -- Shen, H -- Shue, B C -- Siden-Kiamos, I -- Simpson, M -- Skupski, M P -- Smith, T -- Spier, E -- Spradling, A C -- Stapleton, M -- Strong, R -- Sun, E -- Svirskas, R -- Tector, C -- Turner, R -- Venter, E -- Wang, A H -- Wang, X -- Wang, Z Y -- Wassarman, D A -- Weinstock, G M -- Weissenbach, J -- Williams, S M -- WoodageT -- Worley, K C -- Wu, D -- Yang, S -- Yao, Q A -- Ye, J -- Yeh, R F -- Zaveri, J S -- Zhan, M -- Zhang, G -- Zhao, Q -- Zheng, L -- Zheng, X H -- Zhong, F N -- Zhong, W -- Zhou, X -- Zhu, S -- Zhu, X -- Smith, H O -- Gibbs, R A -- Myers, E W -- Rubin, G M -- Venter, J C -- P50-HG00750/HG/NHGRI NIH HHS/ -- U54 HG003273/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2000 Mar 24;287(5461):2185-95.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Celera Genomics, 45 West Gude Drive, Rockville, MD 20850, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10731132" target="_blank"〉PubMed〈/a〉

    Description: The 2,272,351-base pair genome of Neisseria meningitidis strain MC58 (serogroup B), a causative agent of meningitis and septicemia, contains 2158 predicted coding regions, 1158 (53.7%) of which were assigned a biological role. Three major islands of horizontal DNA transfer were identified; two of these contain genes encoding proteins involved in pathogenicity, and the third island contains coding sequences only for hypothetical proteins. Insights into the commensal and virulence behavior of N. meningitidis can be gleaned from the genome, in which sequences for structural proteins of the pilus are clustered and several coding regions unique to serogroup B capsular polysaccharide synthesis can be identified. Finally, N. meningitidis contains more genes that undergo phase variation than any pathogen studied to date, a mechanism that controls their expression and contributes to the evasion of the host immune system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tettelin, H -- Saunders, N J -- Heidelberg, J -- Jeffries, A C -- Nelson, K E -- Eisen, J A -- Ketchum, K A -- Hood, D W -- Peden, J F -- Dodson, R J -- Nelson, W C -- Gwinn, M L -- DeBoy, R -- Peterson, J D -- Hickey, E K -- Haft, D H -- Salzberg, S L -- White, O -- Fleischmann, R D -- Dougherty, B A -- Mason, T -- Ciecko, A -- Parksey, D S -- Blair, E -- Cittone, H -- Clark, E B -- Cotton, M D -- Utterback, T R -- Khouri, H -- Qin, H -- Vamathevan, J -- Gill, J -- Scarlato, V -- Masignani, V -- Pizza, M -- Grandi, G -- Sun, L -- Smith, H O -- Fraser, C M -- Moxon, E R -- Rappuoli, R -- Venter, J C -- New York, N.Y. -- Science. 2000 Mar 10;287(5459):1809-15.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Institute for Genomic Research (TIGR), 9712 Medical Center Drive, Rockville, MD 20850, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10710307" target="_blank"〉PubMed〈/a〉

    Description: One of the rewards of having a Drosophila melanogaster whole-genome sequence will be the potential to understand the molecular bases for structural features of chromosomes that have been a long-standing puzzle. Analysis of 2.6 megabases of sequence from the tip of the X chromosome of Drosophila identifies 273 genes. Cloned DNAs from the characteristic bulbous structure at the tip of the X chromosome in the region of the broad complex display an unusual pattern of in situ hybridization. Sequence analysis revealed that this region comprises 154 kilobases of DNA flanked by 1.2-kilobases of inverted repeats, each composed of a 350-base pair satellite related element. Thus, some aspects of chromosome structure appear to be revealed directly within the DNA sequence itself.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Benos, P V -- Gatt, M K -- Ashburner, M -- Murphy, L -- Harris, D -- Barrell, B -- Ferraz, C -- Vidal, S -- Brun, C -- Demailles, J -- Cadieu, E -- Dreano, S -- Gloux, S -- Lelaure, V -- Mottier, S -- Galibert, F -- Borkova, D -- Minana, B -- Kafatos, F C -- Louis, C -- Siden-Kiamos, I -- Bolshakov, S -- Papagiannakis, G -- Spanos, L -- Cox, S -- Madueno, E -- de Pablos, B -- Modolell, J -- Peter, A -- Schottler, P -- Werner, M -- Mourkioti, F -- Beinert, N -- Dowe, G -- Schafer, U -- Jackle, H -- Bucheton, A -- Callister, D M -- Campbell, L A -- Darlamitsou, A -- Henderson, N S -- McMillan, P J -- Salles, C -- Tait, E A -- Valenti, P -- Saunder, R D -- Glover, D M -- New York, N.Y. -- Science. 2000 Mar 24;287(5461):2220-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The European Bioinformatics Institute, Wellcome Trust Genome Campus, Hinxton Hall, Cambridge CB10 1SD, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10731137" target="_blank"〉PubMed〈/a〉

    Description: The hCHK2 gene encodes the human homolog of the yeast Cds1 and Rad53 G2 checkpoint kinases, whose activation in response to DNA damage prevents cellular entry into mitosis. Here, it is shown that heterozygous germ line mutations in hCHK2 occur in Li-Fraumeni syndrome, a highly penetrant familial cancer phenotype usually associated with inherited mutations in the TP53 gene. These observations suggest that hCHK2 is a tumor suppressor gene conferring predisposition to sarcoma, breast cancer, and brain tumors, and they also provide a link between the central role of p53 inactivation in human cancer and the well-defined G2 checkpoint in yeast.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bell, D W -- Varley, J M -- Szydlo, T E -- Kang, D H -- Wahrer, D C -- Shannon, K E -- Lubratovich, M -- Verselis, S J -- Isselbacher, K J -- Fraumeni, J F -- Birch, J M -- Li, F P -- Garber, J E -- Haber, D A -- New York, N.Y. -- Science. 1999 Dec 24;286(5449):2528-31.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Massachusetts General Hospital Center for Cancer Risk Analysis and Harvard Medical School, Building 149, Charlestown, MA 02129, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10617473" target="_blank"〉PubMed〈/a〉

    Description: We determined the mass of asteroid 433 Eros, its lower order gravitational harmonics, and rotation state, using ground-based Doppler and range tracking of the Near Earth Asteroid Rendezvous (NEAR)-Shoemaker spacecraft and images of the asteroid's surface landmarks. The mass of Eros is (6.687 +/- 0.003) x 10(18) grams, which, coupled with our volume estimate, implies a bulk density of 2. 67 +/- 0.03 grams per cubic centimeter. The asteroid appears to have a uniform density distribution. The right ascension and declination of the rotation pole are 11.37 +/- 0.05 and 17.22 +/- 0.05 degrees, respectively, and at least over the short term, the rotation state of Eros is stable with no measurable free precession of the spin pole. Escape velocities on the surface vary from 3.1 to 17.2 meters per second. The dynamical environment of Eros suggests that it is covered with regolith and that one might expect material transport toward the deepest potential wells in the saddle and 5.5-kilometer crater regions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yeomans -- Antreasian -- Barriot -- Chesley -- Dunham -- Farquhar -- Giorgini -- Helfrich -- Konopliv -- McAdams -- Miller -- Owen Jr -- Scheeres -- Thomas -- Veverka -- Williams -- New York, N.Y. -- Science. 2000 Sep 22;289(5487):2085-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Navigation and Mission Design Section, Jet Propulsion Laboratory, California Institute of Technology, Pasadena, CA 91109, USA.

    Description: Measurements from the Near Earth Asteroid Rendezvous (NEAR)-Shoemaker Laser Rangefinder (NLR) indicate that asteroid 433 Eros is a consolidated body with a complex shape dominated by collisions. The offset between the asteroid's center of mass and center of figure indicates a small deviation from a homogeneous internal structure that is most simply explained by variations in mechanical structure. Regional-scale relief and slope distributions show evidence for control of topography by a competent substrate. Impact crater morphology is influenced by both gravity and structural control. Small-scale topography reveals ridges and grooves that may be generated by impact-related fracturing.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zuber -- Smith -- Cheng -- Garvin -- Aharonson -- Cole -- Dunn -- Guo -- Lemoine -- Neumann -- Rowlands -- Torrence -- New York, N.Y. -- Science. 2000 Sep 22;289(5487):2097-101.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth, Atmospheric, and Planetary Sciences, Massachusetts Institute of Technology, Cambridge, MA 02139, USA.

    Description: The effects of increasing carbon dioxide (CO2) and climate on net carbon storage in terrestrial ecosystems of the conterminous United States for the period 1895-1993 were modeled with new, detailed historical climate information. For the period 1980-1993, results from an ensemble of three models agree within 25%, simulating a land carbon sink from CO2 and climate effects of 0.08 gigaton of carbon per year. The best estimates of the total sink from inventory data are about three times larger, suggesting that processes such as regrowth on abandoned agricultural land or in forests harvested before 1980 have effects as large as or larger than the direct effects of CO2 and climate. The modeled sink varies by about 100% from year to year as a result of climate variability.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schimel, D -- Melillo, J -- Tian, H -- McGuire, A D -- Kicklighter, D -- Kittel, T -- Rosenbloom, N -- Running, S -- Thornton, P -- Ojima, D -- Parton, W -- Kelly, R -- Sykes, M -- Neilson, R -- Rizzo, B -- New York, N.Y. -- Science. 2000 Mar 17;287(5460):2004-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max-Planck-Institute for Biogeochemistry, Postfach 10 01 64, D-07701 Jena, Germany. dschimel@bgc-jena.mpg.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10720324" target="_blank"〉PubMed〈/a〉

    Description: With accumulating evidence indicating the importance of cytotoxic T lymphocytes (CTLs) in containing human immunodeficiency virus-1 (HIV-1) replication in infected individuals, strategies are being pursued to elicit virus-specific CTLs with prototype HIV-1 vaccines. Here, we report the protective efficacy of vaccine-elicited immune responses against a pathogenic SHIV-89.6P challenge in rhesus monkeys. Immune responses were elicited by DNA vaccines expressing SIVmac239 Gag and HIV-1 89.6P Env, augmented by the administration of the purified fusion protein IL-2/Ig, consisting of interleukin-2 (IL-2) and the Fc portion of immunoglobulin G (IgG), or a plasmid encoding IL-2/Ig. After SHIV-89.6P infection, sham-vaccinated monkeys developed weak CTL responses, rapid loss of CD4+ T cells, no virus-specific CD4+ T cell responses, high setpoint viral loads, significant clinical disease progression, and death in half of the animals by day 140 after challenge. In contrast, all monkeys that received the DNA vaccines augmented with IL-2/Ig were infected, but demonstrated potent secondary CTL responses, stable CD4+ T cell counts, preserved virus-specific CD4+ T cell responses, low to undetectable setpoint viral loads, and no evidence of clinical disease or mortality by day 140 after challenge.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Barouch, D H -- Santra, S -- Schmitz, J E -- Kuroda, M J -- Fu, T M -- Wagner, W -- Bilska, M -- Craiu, A -- Zheng, X X -- Krivulka, G R -- Beaudry, K -- Lifton, M A -- Nickerson, C E -- Trigona, W L -- Punt, K -- Freed, D C -- Guan, L -- Dubey, S -- Casimiro, D -- Simon, A -- Davies, M E -- Chastain, M -- Strom, T B -- Gelman, R S -- Montefiori, D C -- Lewis, M G -- Emini, E A -- Shiver, J W -- Letvin, N L -- AI-65301/AI/NIAID NIH HHS/ -- AI-85343/AI/NIAID NIH HHS/ -- CA-50139/CA/NCI NIH HHS/ -- P01 AI041521/AI/NIAID NIH HHS/ -- R01 CA050139/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 2000 Oct 20;290(5491):486-92.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Beth Israel Deaconess Medical Center, Harvard Medical School, 330 Brookline Avenue, Boston, MA 02215, USA. dan_barouch@hotmail.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11039923" target="_blank"〉PubMed〈/a〉

    Description: Radar observations of the main-belt, M-class asteroid 216 Kleopatra reveal a dumbbell-shaped object with overall dimensions of 217 kilometers by 94 kilometers by 81 kilometers (+/-25%). The asteroid's surface properties are consistent with a regolith having a metallic composition and a porosity comparable to that of lunar soil. Kleopatra's shape is probably the outcome of an exotic sequence of collisional events, and much of its interior may have an unconsolidated rubble-pile structure.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ostro -- Hudson -- Nolan -- Margot -- Scheeres -- Campbell -- Magri -- Giorgini -- Yeomans -- New York, N.Y. -- Science. 2000 May 5;288(5467):836-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Jet Propulsion Laboratory, California Institute of Technology, Pasadena, CA 91109-8099, USA.

    Description: Optically induced entanglement is identified by the spectrum of the phase-sensitive homodyne-detected coherent nonlinear optical response in a single gallium arsenide quantum dot. The electron-hole entanglement involves two magneto-excitonic states differing in transition energy and polarization. The strong coupling needed for entanglement is provided through the Coulomb interaction involving the electrons and holes. The result presents a first step toward the optical realization of quantum logic operations using two or more quantum dots.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen -- Bonadeo -- Steel -- Gammon -- Katzer -- Park -- Sham -- New York, N.Y. -- Science. 2000 Sep 15;289(5486):1906-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Harrison M.
