  1. 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...
  2. The quest for population III.

    Science 295(5552):66 (2002) PMID 11778036

  3. 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...
  4. The formation of the first star in the Universe.

    Science 295(5552):93 (2002) PMID 11711636

    We describe results from a fully self-consistent three-dimensional hydrodynamical simulation of the formation of one of the first stars in the Universe. In current models of structure formation, dark matter initially dominates, and pregalactic objects form because of gravitational instability fr...
  5. Solar system exploration. Tight budget makes for an uncertain future.

    Science 295(5552):38 (2002) PMID 11778025

  6. 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...
  7. Fluorescent signaling in parrots.

    Science 295(5552):92 (2002) PMID 11778040

  8. Geophysics. Caught offside.

    Science 295(5552):55 (2002) PMID 11778031

  9. The runts of the cosmic litter.

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

  10. The initial mass function of stars: evidence for uniformity in variable systems.

    Science 295(5552):82 (2002) PMID 11778039

    The distribution of stellar masses that form in one star formation event in a given volume of space is called the initial mass function (IMF). The IMF has been estimated from low-mass brown dwarfs to very massive stars. Combining IMF estimates for different populations in which the stars can be ...
