Greater access to higher education could have reversed EU referendum result

New research from the University of Leicester suggests that greater access to higher education was a predominant factor in the 2016 EU referendum outcome. An increase of 3% in British adults accessing higher education could have reversed the result, while a decrease in turnout in England and Wales may also have changed the outcome.

New CubeSat propulsion system uses water as propellant

A new micropropulsion system for CubeSats uses an innovative design of tiny nozzles that release precise bursts of water vapor to maneuver the spacecraft. The FEMTA thruster technology demonstrates a thrust-to-power ratio of 230 micronewtons per watt, making it a viable method for attitude control of CubeSats.
