Regular Monthly Meeting

  We have our regular monthly meeting at Books-A-Million in Colonial Heights this coming Sunday.

  Everyone with an interest in science and/or science fiction is welcome to join us.

Entangled photons enhance fluorescence imaging

  Two-photon excitation microscopy is used to image living tissue.  The fluorescence technique uses infrared light and allows deeper penetration of tissue than traditional fluorescence imaging.  But the two-photon process is inefficient for organic materials.  One solution is to increase the intensity of light directed at a sample, but this may damage the sample.  Another solution is to use entangled photons, reports a group led by T. G. Goodson of the University of Michigan.  They report that the technique could enhance two-photon imaging by 10 orders of magnitude.

NASA to Attempt Fix for Planet-Hunting Kepler Spacecraft This Month

I am reading this article NASA to Attempt Fix for Planet-Hunting Kepler Spacecraft This Month by Mike Wall, SPACE.com Senior Writer. According to this article, Kepler Spacecraft has detected over 3,000 alien planets since march 2009.
