This week in Science

mitotic spindle 95.bmpThis week in Science Express, researchers Gohta Goshima, Roy Wollman,
Ronald D. Vale
and Nico Stuurman at the Marine Biological Laboratory at Woods Hole report on a genome screen that revealed about 200 genes -- 150 of them previously unknown or unexpected -- that are involved in assembling the mitotic spindle (left), the structure that separates chromosomes during cell division and plays a role in human diseases, including cancer.
