  • DNA Assembles Materials From the Ground Up

    On page 594 of this week's issue of Science, researchers report using DNA as tweezers to pick up compounds and place them where they're wanted. The technique could help researchers put chains of molecules together to answer questions such as how different enzymes work together in a series.

  • Aging of the Ovary Linked to PTEN Pathway

    On page 611 of this week's issue of Science, researchers report that in the absence of a gene called Pten, the egg-containing follicles of mice were activated rapidly at an early age, thus causing depletion of the animals' eggs much sooner than is normal--a situation similar to that of premature ovarian failure in humans.
