Nature 420:591
1.Minimal standard for proteomics has been set to ensure consistence
of data. http://psidev.sourceforge.net
Sex and evolution 420:664

2.Benefits of sex, particularly in a large population, has been
addressed in evolution of single-celled chlorophyte C.
reinhardtii.

3.From operon to gene clusters 420:666
Expressions of functionally related genes in prokaryotes are
regulated in the form of operon, while in eukaryotes there
are clustering of co-expressed, non-homolgous genes that
implies their co-regulation. This work has analyzed genome-
wide distribution of co-expressed gene in Drosophila.

4.Conformational masking in HIV 420:678
Entropies for antibodies binding to HIV gp120 have been
measured, which suggests a conformational change that
masks neurtalization by these antibodies.

5.Determination of asymmetric inheritance in embryo development
by different mRNAs located on the centrosome 420:682
Asymmetric distribution of patterning molecules determines
the cell fate, and asymmetric inheritance is known to occur
either through directed transport of the molecules along actin
or capture of them by a region of cortex. This work shows
importance of mRNAs located on the centrosome in this process.
