A newly discovered way for cells to die

Some cells are meant to live, and some are meant to die. For example, the linker cell of C. Elegans, a favored model organism for biologists, is among those destined for termination. This cell helps determine the shape of the gonad in male worms–and then it dies, after two days, just as the worms are transitioning from larvae into adults. This programmed cell death is a normal part of the animal’s development, yet the genetic and molecular mechanisms underpinning it have not been worked out.
