In vertebrates and higher eukaryotes such as Caenorhabditis elegans and Drosophila melanogaster, microtubules are in each cell primarily nucleated and organized by the centrosome, which has as its center a pair of centrioles. In recent years, it has become clear that bipolar spindle assembly is possible without centrosomes, and it appears that the centrosome might be required for proper spindle positioning rather than for spindle assembly.

On page 32 of this issue, a joint team from the Genome Sequencing Center (St. Louis, USA) and the newly founded Sanger Centre (Hinxton Hall, Cambridge, UK) report a contiguous sequence of over two megabases from chromosome III of the nematode worm, Caenorhabditis elegans. This is the longest contiguous DNA sequence yet determined, and it prompts rumination on how far we have come in the sequencing enterprise, and on how far - and where - we have

Cowabugna, dudes! Those lean, gene-revealing machines have scored a most totally excellent victory in the battle to understand aging. We are, of course, talking about mutant ninja nematodes here. At a conference on aging in January at Cold Spring Harbor's Banbury Center, Thomas Johnson of the Institute for Behavioral Genetics at the University of Colorado in Boulder brought some dudes and dudettes from Capitol Hill up to date on the latest awesome achievements of the bodacious beasts know as Caenorhabditis elegans.

Geoffrey Gold, a physiologist at the Monell Chemical Senses Center in Philadelphia, had wanted for years to put to rest a nagging question: How do odors trigger olfactory neurons to fire off action potentials to the brain? The dogma for the past 5 years had been that odors fall into two catagories, each of which acts via a different inracellular messenger molecule. But Gold believed this view was wrong, and that all odors work by increasing the production of the intracellular messenger cyclic AMP (cAMP). One day last spring, Gold got a phone call out of the blue from neurobiologist John Ngai, at the University of California (UC), Berkeley, offering the possibility of answering this question. It was my dream come true," says Gold. ......

In the end, it is attention to detail that makes all the difference. It's the center fielder's extra two steps to the left, the salesman's memory for names, the lover's phone call, the soldier's clean weapon. It is the thing that separates the men from the boys, and, very often, the living from the dead. Professional success depends on it, regardless of the field. But in big-time genetic research, attention to detail is more than just a good work habit, more than a necessary part of the routine. In big-time genetic research, attention to detail is the very meat and the god of science. It isn't something that's expected; it is simply the way of things. Those in the field, particularly those who lead the field, are slaves to detail. They labor in submerged mines of it, and haul great loads of it up from the bottom of an unseen ocean-the invisible sea of biological phenomena, upon which all living things float. Detail's rule over genetics is total and cruel. Months and even years of work have literally gone down the drain because of the most minor miscalculations. Indeed, perhaps the greatest discovery in the history of the discipline-the double-helix structure of DNA-might have been made by Linus Pauling instead of James D. Watson and Francis H. C. Crick. But Pauling's equations contained a simple mistake in undergraduate-level chemistry, a sin against detail that is now part of the legend. Each of the six scientists singled out here has made his mark by mastering his own particular set of
