A star's life: born in a group, dies alone
Article Abstract:
Astronomer Karen Strom and her colleagues discovered evidence that stars form in clusters of 10 to 50 members. The groups are too small to produce a gravitational pull strong enough to keep the stars together permanently; they eventually pull away from one another and live most of their lives alone.

Artificial atom unveils quantum effects
Article Abstract:
Ray Ashoori of MIT has developed an artificial atom in which as few as one or two electrons are confined by electric fields and observable for quantum effects. The device, based on a gallium arsenide thin layer, enables study of the effect of magnetic fields on a pair of electrons.
