Surface tension effects in a coherent liquid of light
Escuela de Ingeniería Aeronáutica y del Espacio, Spain
We show through numerical simulations that a laser beam which propagates through an optical medium with Kerr (focusing) and higher order (defocusing) nonlinearities displays interesting surface-tension properties analogous to a coherent liquid. Among the most important effects, we notice the formation of unstable rarefaction pulses, analogous to those described in superfluid He. These dark structures decay on vortex-antivortex pairs of high stability.

TINY: A portable tool for nucleic acid quantification in resource limited settings
Ryan Snodgrass, David Erickson
Cornell University, United States of America
TINY is a system that delivers nucleic acid quantification capability to resource limited settings. It may be heated via sunlight, open flame, or hotplate (it can use, but does not require electricity). It is portable and uses inexpensive optical components. We test the quantification capabilities of TINY using extracted DNA samples from Kaposi’s sarcoma (KS) patients in Uganda and San Francisco, CA. Our data shows that nucleic acid quantification is possible by comparing the threshold amplification time of positive samples. We will report a sensitivity and specificity of our system when compared to commercial qPCR machines as well as to histopathology.
