Evidence Mounts Against Pentaquarks
 By
Heather Rock Woods
They’re
exotic. So exotic they may not exist. Pentaquarks are
mysterious particles—whose existence is still in question—composed of

quantum numbers cannot be reduced down to those of regular baryons.

Second GLAST Tower Installed
By
Matthew Early Wright
GLAST
has started to take physical shape with the installation of the second
tracking tower last month. Now the team can perform the first tests ever
of multiple towers in the grid array. Researchers expect to learn much
about how the towers and the analysis software will cooperate to
eventually produce sharp images of the gamma-ray sky.

in the work we do here at the Lab.
We have to remember, though, that they are young and need our help and
instruction to identify and avoid safety hazards.
