NASA to study atmospheric storms that disrupt radio waves

A NASA-funded sounding rocket mission will help better understand and predict the electrical storms in Earth's upper atmosphere, which can interfere with satellite communication and global positioning signals.

The mission, called Equatorial Vortex Experiment (EVEX) will launch two rockets for a twelve-minute journey through the equatorial ionosphere from an atoll in the Pacific in the next few weeks.

C'mon radio, let's do the twist

Wave innovation might dramatically increase bandwidth, researcher says
By Devin Powell
Scientists have demonstrated a way to mold radio waves into spirals that could allow multiple radio stations to broadcast at the same frequency. Two waves with different shapes can carry different information without overlapping or interfering with each other.
