  • Less chewing the cud, more greening the fuel
    on January 8, 2018 at 2:02 pm

    Plant biomass contains considerable calorific value but most of it makes up robust cell walls, an unappetizing evolutionary advantage that helped grasses to survive foragers and prosper for more than 60 million years. The trouble is that this robustness still makes them less digestible in the rumen of cows and sheep and difficult to process in bioenergy refineries for ethanol fuel. Until now, with the discovery of a gene that controls that robustness. […]

  • New procedures for DNA stability
    on November 16, 2017 at 3:50 pm

    In eukaryotic cells the proximity of the genes to the nuclear pores, which are found in the nuclear membrane, contributes to maintaining the integrity of the genome. This is due to the fact that the anchoring of DNA to the pore during transcription avoids the formation of DNA-RNA hybrids, which are a natural source of DNA breaks and genome instability. […]
