  1. Comment on "Revealing nature's cellulase diversity: the digestion mechanism of Caldicellulosiruptor bescii CelA".

    Science 344(6184):578 (2014) PMID 24812381

    Brunecky et al. (Reports, 20 December 2013, p. 1513) compared the cellulolytic activity of bacterial multimodular cellulase CelA with fungal Cel7A (cellobiohydrolase I from Trichoderma reesei). If more active Cel7A from another fungus were used as a reference enzyme under optimal conditions with ...
  2. A Useful Selective Bactericidal Property of Tergitol-7.

    Science 103(2687):758 (2010) PMID 17836453

    Starch tryptone agar containing 1 : 20,000 Tergitol-7 was successfully sterilized in the Arnold by one 30-minute heating period. Decreasing the concentration to 1 : 30,000 resulted in 4 per cent failures. A concentration of 1 : 20,000 in the cold killed spores of B. mycoides and an unidentified h...
  3. Solar system exploration. Researchers fear merger could muffle their voice.

    Science 295(5552):37 (2002) PMID 11778024

  4. Solar system exploration. Technology is essential, but it's a tough sell.

    Science 295(5552):39 (2002) PMID 11778026

  5. Nuclear science. U.S. breeder reactor runs out of lives.

    Science 295(5552):31 (2002) PMID 11778020

  6. Antibiotic resistance. Livestock feed ban preserves drugs' power.

    Science 295(5552):27 (2002) PMID 11778017

  7. Cosmology. How the cosmic dark age ended.

    Science 295(5552):51 (2002) PMID 11778028

  8. Surface science. Water on a metal surface.

    Science 295(5552):58 (2002) PMID 11778032

  9. Germ cell survival through carbohydrate-mediated interaction with Sertoli cells.

    Science 295(5552):124 (2002) PMID 11778047

    Spermatogenesis is a precisely regulated process in which the germ cells closely interact with Sertoli cells. The molecular basis of this cell-cell adhesion is unknown. Here, we demonstrate that targeted disruption of Man2a2, a gene encoding alpha-mannosidase IIx (MX), an enzyme that forms inter...
  10. Combined functional genomic maps of the C. elegans DNA damage response.

    Science 295(5552):127 (2002) PMID 11778048

    Many human cancers originate from defects in the DNA damage response (DDR). Although much is known about this process, it is likely that additional DDR genes remain to be discovered. To identify such genes, we used a strategy that combines protein-protein interaction mapping and large-scale phen...
  11. A one-step conversion of benzene to phenol with a palladium membrane.

    Science 295(5552):105 (2002) PMID 11778042

    Existing phenol production processes tend to be energy-consuming and produce unwanted by-products. We report an efficient process using a shell-and-tube reactor, in which a gaseous mixture of benzene and oxygen is fed into a porous alumina tube coated with a palladium thin layer and hydrogen is ...
  12. Role of cell-specific SpoIIIE assembly in polarity of DNA transfer.

    Science 295(5552):137 (2002) PMID 11778051 PMCID PMC2885158

    SpoIIIE mediates postseptational chromosome partitioning in Bacillus subtilis, but the mechanism controlling the direction of DNA transfer remains obscure. Here, we demonstrated that SpoIIIE acts as a DNA exporter: When SpoIIIE was synthesized in the larger of the two cells necessary for sporula...
  13. Constraints on melt movement beneath the East Pacific Rise from 230Th-238U disequilibrium.

    Science 295(5552):107 (2002) PMID 11778043

    We report 230Th-238U disequilibrium data on mid-ocean ridge basalts recovered 5 to 40 kilometers off the ridge axis near 9 degrees 30'N of the East Pacific Rise. These data indicate near-symmetrical eruptions of normal mid-ocean ridge basalts (NMORBs) and incompatible element-enriched mid-ocean ...

    Science 295(5552):59 (2002) PMID 11778033

  15. The runts of the cosmic litter.

    Science 295(5552):64 (2002) PMID 11778035

  16. Formation of recent martian debris flows by melting of near-surface ground ice at high obliquity.

    Science 295(5552):110 (2002) PMID 11729267

    The observation of small gullies associated with recent surface runoff on Mars has renewed the question of liquid water stability at the surface of Mars. The gullies could be formed by groundwater seepage from underground aquifers; however, observations of gullies originating from isolated peaks...

    Science 295(5552):28 (2002) PMID 11778018

  18. Nucleotide variation along the Drosophila melanogaster fourth chromosome.

    Science 295(5552):134 (2002) PMID 11778050

    The Drosophila melanogaster fourth chromosome, believed to be nonrecombining and invariable, is a classic example of the effect of natural selection in eliminating genetic variation in linked loci. However, in a chromosome-wide assay of nucleotide variation in natural populations, we have observ...
  19. Clustered star formation and the origin of stellar masses.

    Science 295(5552):68 (2002) PMID 11778037

    Star clusters are ubiquitous in galaxies of all types and at all stages of their evolution. We also observe them to be forming in a wide variety of environments, ranging from nearby giant molecular clouds to the supergiant molecular clouds found in starburst and merging galaxies. The typical sta...
  20. Extension of life-span in Caenorhabditis elegans by a diet lacking coenzyme Q.

    Science 295(5552):120 (2002) PMID 11778046

    The isoprenylated benzoquinone coenzyme Q is a redox-active lipid essential for electron transport in aerobic respiration. Here, we show that withdrawal of coenzyme Q (Q) from the diet of wild-type nematodes extends adult life-span by approximately 60%. The longevity of clk-1, daf-2, daf-12, and...
