Following a career in science involves long hours and hard work, but as Eve Marder explains in the first of a series of columns, it can also be extremely rewarding.

Preventing premature interactions between microtubules and protein-based structures called kinetochores ensures that chromosomes are segregated by meiosis rather than mitosis in reproductive cells.
