Ten Top Physics Stories for 2007
In chronological order during the year:

Light, slowed in one Bose Einstein condensate (BEC), is passed on to another B
EC
(

http://www.aip.org/pnu/2007/split/812-1.html);

Electron tunneling in real time can be observed with the use of attosecond pul
ses
(

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 dis
missing the possibility of a fourth species of neutrino (

http://www.aip.org/pn
u/2007/split/820-1.html);

The Tevatron, in its quest to observe the Higgs boson, updated the top quark m
ass 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);

Based on data recorded at the Auger Observatory, astronomers conclude that the
highest energy cosmic rays come from active galactic nuclei (

http://www.aip.o
rg/pnu/2007/split/846-1.html);

And the observation of Cooper pairs in insulators (

http://www.aip.org/pnu/2007
/split/849-1.html).
