    The DNA Replication Complex, an assembly of proteins that synthesizes new DNA before cell division.  It consists of Helicase, Primase, Single-strand binding proteins, and DNA polymerase III.  Because DNA strands can only be copied in one direction, the complex must pull out loops of one strand and replicate it in fragments.  At this moment there are hundreds of trillions of these molecular machines in constant activity within your body.

    On April 11 at 8:30 UTC, an M6 class solar flare occurred on the Sun.  It produced a CME that is projected to reach the Earth on April 13th.  It will cause a geomagnetic storm and aurora should be visible at lower latitudes.  The best way to monitor the location of aurora is with the realtime NOAA Aurora Map.  You can get precise weather predictions for your location with the ClearDarkSky Astronomy forecast.  Seeing the aurora can be a life changing experience, good luck!
