Electromagnetic signals are produced by aqueous nanostructures derived from bacterial DNA sequences.

Abstract: A novel property of DNA is described: the capacity of some bacterial DNA sequences to induce electromagnetic waves at high aqueous dilutions. It appears to be a resonance phenomenon triggered by the ambient electromagnetic background of very low frequency waves. The genomic DNA of most pathogenic bacteria contains sequences which are able to generate such signals. This opens the way to the development of highly sensitive detection system for chronic bacterial infections in human and animal diseases

Study of Turn-to-Turn Electrical Breakdown for Superconducting Fault Current Limiter Applications

International audienceThe rational insulation design of a resistive superconducting fault current limiter (r-SCFCL) requires data gathered from experimental setups representative of the final apparatus. Therefore, an experimental study was performed to characterize the electrical breakdown (BD) of liquid nitrogen in the particular conditions of a quenching superconducting device. To reproduce the electrical stress occurring within a real r-SCFCL winding, BD voltages with a grounded tape electrode were investigated with different polarities and pressures, with and without transient heating on the tape electrode. Pictures obtained with a high-speed camera and breakdown delay measurements allow to further characterize breakdown mechanisms
