In chronological order during the year:
light, slowed in one Bose Einstein condensate (BEC), is passed on to another BEC (http://www.aip.org/pnu/2007/split/812-1.html);
electron tunneling in real time can be observed with the use of attosecond pulses (http://www.aip.org/pnu/2007/split/818-2.html);
laser cooling of coin-sized object, at least in one dimension (http://www.aip.org/pnu/2007/split/818-1.html);
the best test ever of Newton’s second law, using a tabletop torsion pendulum (http://www.aip.org/pnu/2007/split/819-1.html);
first Gravity Probe B first results, the measurement of the geodetic effect—the warping of spacetime in the vicinity of and caused by Earth-to a precision of 1%, with better precision yet to come (http://www.aip.org/pnu/2007/split/820-2.html).
The MiniBooNE experiment at Fermilab solves a neutrino mystery, apparently dismissing the possibility of a fourth species of neutrino (http://www.aip.org/pnu/2007/split/820-1.html);
the Tevatron, in its quest to observe the Higgs boson, updated the top quark mass and observed several new types of collision events, such as those in which only a single top quark is made, and those in which a W and Z boson or two Z bosons are made simultaneously (http://www.aip.org/pnu/2007/split/821-1.html);
the shortest light pulse, a 130-attosecond burst of extreme ultraviolet light (http://www.aip.org/pnu/2007/split/823-1.html);

How to climb the academic ladder
Late one night, Richard J. Radke was at his desk, putting together applications for faculty jobs. Nearing the completion of his Ph.D., he was hoping to embark on an academic career. A senior professor he knew well took Radke aside and said, “I hate to tell you this, but it’s going to be brutal,” he recalls. Radke, now an assistant professor in electrical, computer, and systems engineering at Rensselaer Polytechnic Institute, in Troy, N.Y., admits that his professor was right. Even once he’d landed a job, for the first few years he was constantly busy and stressed out as he learned the ropes and started worrying about tenure.
