How best to treat infections and tumors: Choice of containment versus aggressive treatment depends on drug resistance

Treatment designed to contain, rather than eliminate, chronic infections or tumors where drug resistance can emerge may delay treatment failure.

A tale of two pulsars' tails: Plumes offer geometry lessons to astronomers
An artist’s representation of what the three unusual tails of the pulsar Geminga may look like close up. NASA's Chandra X-ray Observatory is giving astronomers a better look at pulsars and their associated pulsar wind nebulae, enabling new constraints on the geometry of pulsars and why they look the way they do from Earth.
