Optogenetic Defibrillation Terminates Ventricular Arrhythmia

Speaker: David Fernandez

Researchers from University of Bonn, Germany and John Hopkins University, Maryland, USA explored the use of a light sensitive channel, called ChR2, in cardiac tissue to terminate ventricular arrhythmia. The group in Bonn reported successfully terminating ventricular arrhythmia in mice with ChR2. The group in Maryland reported successfully terminating ventricular tachycardia in a virtual human-heart model. These results can lead to the potential of a safer and painless alternative to implanted electrical defibrillators.

Optically Pumped CO2 Laser and Plasma Mirror for Atmospheric Remote Sensing

Speaker: Anton Shutov

Will discuss an idea how CO2 presented in air can be turned into a laser or simply how CO2 laser can be pumped optically. This type of CO2 laser is pumped via Raman vibrational mode excitation of nitrogen presented in the air, making possible remote monitoring of CO2 level. Another proposed technique for atmospheric remote sensing benefits from light scattered by plasma mirror in backward direction. The scattered light can be further amplified by Stimulated Raman scattering.
