 A Princeton-led research group has discovered an isolated community of
bacteria nearly two miles underground that derives all of its energy
from the decay of radioactive rocks rather than from sunlight.
According to members of the team, the finding suggests life might exist
in similarly extreme conditions even on other worlds.

 Feverish fruit fly larvae, warmed in a toasty lab chamber, are
giving Cornell researchers a way to watch chromosomes in action and
actually see how genes are expressed in living tissue. Using multiphoton fluorescence microscopy, a technique pioneered at
Cornell by physicist Watt W. Webb, researchers have for the first time
been able to watch chromosomes change their form in order to activate
their genes to synthesize key proteins in fruit fly cells. The advance
could be a significant step toward understanding the basic processes
that underlie gene expression.

 Using computer simulations and experimental results, researchers at
the University of Illinois at Urbana-Champaign and the University of
Arizona have identified a key component of the gating mechanism in
aquaporins that controls both the passage of water and the conduction
of ions.

 Like a 1950's Detroit automaker, it
appears that nature prefers to build its proteins around a solid,
sturdy chassis. A new study combining advanced computational
modeling and cutting-edge experiments by molecular biologists at Rice
University and Baylor College of Medicine suggests that the most stable
parts of a protein are also the parts that fold first. The findings appear in the Sept. 13 issue of the journal Structure.
