 The composition of lipid membranes, similar to those that surround
living cells, can now be mapped at the nanometer scale. The work, by
researchers at Stanford University, the Lawrence Livermore National
Laboratory and UC Davis, is published in the Sept. 29 issue of the
journal Science.
All living cells are wrapped in a
double-layered membrane of fatty lipid molecules. Components of the
membrane can move sideways and organize into patches or other
structures. This organization can affect, for example, important cell
functions and vulnerability to viruses.

 A new theoretical assessment of data taken by the Wilkinson Microwave Anisotropy Probe (WMAP) suggests that the universe -- at least that part of it that can be observed -- is not spherically symmetric, but more like an ellipsoid.

 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.

 In the submicroscopic world -- the domain of elementary particles and
individual atoms -- things behave in the strange, counter-intuitive
fashion governed by the principles of quantum mechanics. Nothing (or so
it seems) like our macroscopic world -- or even the microscopic world
of cells or bacteria or dust particles -- where Newton's much more
reasonable laws keep things sensibly ordered.

 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.
