Albert Einstein's 90-year-old general theory of relativity has just been put through a series of some of its most stringent tests yet, and it has passed each one with flying colors. Radio observations show that a recently discovered binary pulsar is behaving in lockstep accordance with Einstein's theory of gravity in at least four different ways, including the emission of gravitational waves and bizarre effects that occur when massive objects slow down the passage of time.
(emphasis mine)

I thought that gravitational waves have never been detected, which Gravity Probe B was supposed to remedy.
Yeah, wonder how do they infer that.
I think the GR prediction is that gravitational waves would carry away energy from the binary pulsar thus causing the orbits to shrink. The results from this test showed the orbit is shrinking by 7 millimeters a day in accordance with the GR prediction. This would seem to be evidence that gravitational waves are real and behave as GR predicts.
