DNase H activity of Neisseria meningitidis Cas9
Many strains of the human pathogen Neisseria meningitidis carry a compact Cas9 (NmeCas9) that can serve to limit genetic exchange via natural transformation. Cas9 orthologues (including NmeCas9) have recently been adopted for RNA-guided genome engineering and DNA binding, adding to the need to define better their activities and properties. The present invention examines DNA cleavage activities and substrate requirements of NmeCas9, including a set of unusually complex PAM recognition patterns. Unexpectedly, NmeCas9 is found able to cleave single-stranded DNA (ssDNA) targets in a manner that is RNA-guided but both PAM- and tracrRNA-independent. Beyond the requirement for guide-target pairing, this activity has no apparent sequence requirements, and the cleavage sites are measured from the 5′ end of the DNA substrate's RNA-paired region. These results indicate that tracrRNA domains are not strictly required for enzymatic activation of NmeCas9, and expand the list of targeting activities exhibited by these revolutionary RNA-guided nucleases. |

A process for enhanced anaerobic digestion of sludge by alcoholization of food waste, comprising steps of: (1) ethanol prefermentation of food waste—feeding the food waste having been crushed into a uniform grain size into an ethanol production reactor, where the food waste is subjected to rapid and efficient anaerobic fermentation activated by addition of yeast and pH adjustment to produce ethanol and obtain a fermentation broth and a fermentation residue; (2) sludge pretreatment—pretreating the sludge after mixing with the fermentation residue; and (3) methanogenesis of anaerobic digestion—subjecting products resulting from the sludge pretreatment to be mixed with the fermentation broth and then to methanogenesis of anaerobic digestion in a methane production reactor. With this process, the sludge and the food waste can be treated efficiently via multi-phase reactions, and the resource recovery and biogas quality can be enhanced. |

Radical anion functionalization of two-dimensional materials
A radical anion based functionalization of two-dimensional (2D) layered materials is proposed. The covalent functionalization of the basal plane of 2D materials with charge neutral radicals is typically unstable to reduction, leading to detachment of the functional groups from the basal plane upon reduction. This instability hinders the use of functionalized 2D materials as rechargeable electroactive species, unless the functional groups are bound to the edges of the 2D material. However, to achieve high capacity without the creation of many edges and defects, a stable functionalization of the basal plane in the reduced state is required. This goal can be achieved by radical anion functionalization, whereby the reduced/discharged state of the basal-plane-functionalized 2D material is produced. The product of the radical anion functionalization can be used as the discharged state of a cathode active material, solid electrolyte or part of a polymer composite. |

Control system for vehicle
A control system for a vehicle to prevent a reduction in a drive force due to increase in an internal resistance of a battery. A controller calculates a command value of an output power of the battery to be transmitted to a motor in future, and predicts an internal resistance of the battery at the point to discharge the electric power from the battery in the amount of the command value. If it is expected that the battery will not be possible to discharge the electric power in the amount of the command value, the controller reduces a load on the battery by increasing an amount of the electric power supplied to the motor from the generator before the battery can no longer discharge the electric power in the amount of the command value. |
