Multiple Copies of Ribosomal RNA Genes Aid Yeast Genome Integrity
Japanese researchers identified mechanisms through which ribosomal RNA gene sequences help protect the genome following DNA damage by comparing four Saccharomyces cerevisiae strains with 20, 40, 80, or 110 copies of genes coding for rRNA. They found that strains with fewer copies of rDNA genes were more sensitive to DNA damage by chemicals or ultraviolet light, apparently due to a role for these rDNA copies in recombination repair and sister chromatid cohesion.
Team Maps Methylome During Cellular Differentiation
Laurent, Wong, et al, Genome Research
Using bisulfite sequencing with the Illumina Genome Analyzer, researchers from Singapore and the US mapped and compared DNA methylation patterns in human cells during three progressive stages of differentiation: embryonic stem cells, skin-like cells derived from embryonic stem cells, and primary neonatal skin cells. In the process, the team identified shared and cell type-specific methylation patterns, providing insights into how gene regulation shifts during development.

But, risky science is also
But, risky science is also novel science. If everything is known and done there would be no research left to do?????
Its also established groups
Its also established groups scratching each others back and doling out money, as in science it cannot be just a blind review of work anyways. Rather allow young risk takers to come to forefront with their novel ways and means to answer tough questions. Give them less but give them enough to survive the big bad world of academic-lead investigator driven individual groups.
Sometimes risky sciences are
Sometimes risky sciences are not funded by RO1. I think risky science which can be high-rsk and high-impact should also be funded by RO1. The other mechanisms for risky sciences are small grants for very short duration and not best. The funding agencies should open their doors and minds (for RO1s) to risky science (which can be innovative and novel). Yes, more often the large and established group (club) help each other with funding. Make sure you give certain percentage of funding (any mechanims) to younger and less established scientists.
