Probing dark matter at the LHC using vector boson fusion processes.

Vector boson fusion processes at the Large Hadron Collider (LHC) provide a unique opportunity to search for new physics with electroweak couplings. A feasibility study for the search of supersymmetric dark matter in the final state of two vector boson fusion jets and large missing transverse energy is presented at 14 TeV. Prospects for determining the dark matter relic density are studied for the cases of wino and bino-Higgsino dark matter.

Mapping the DNA-binding domain and target sequences of the Streptomyces peucetius daunorubicin biosynthesis regulatory protein, DnrI.

Streptomyces antibiotic regulatory proteins (SARPs) constitute a novel family of transcriptional activators that control the expression of several diverse anti-biotic biosynthetic gene clusters. The Streptomyces peucetius DnrI protein, one of only a handful of these proteins yet discovered, controls the biosynthesis of the polyketide antitumour antibiotics daunorubicin and doxorubicin. Recently, comparative analyses have revealed significant similarities among the predicted DNA-binding domains of the SARPs and the C-terminal DNA-binding domain of the OmpR family of regulatory proteins.
