Over the last year, the greatest development in pulsar research at the Arecibo Observatory has been the start of the main ALFA pulsar survey. ... A great example of the new, compact binary systems that ALFA can find is PSR J1906+0746. This is a 144-ms pulsar in a binary system with an orbital period just under 4 hours and a massive companion. ... One particularity of this system is that it is about 1000 times younger than the double pulsar , i.e., it is by far the youngest binary system known. ...
