A team of scientists from CoorsTek Membrane Sciences, the University of Oslo (Norway), and the Instituto de Tecnología Química (Spain) has developed a new process to use natural gas as raw material for aromatic chemicals. The process uses a novel ceramic membrane to make the direct, non-oxidative conversion of gas to liquids possible for the first time — reducing cost, eliminating multiple process steps, and avoiding any carbon dioxide (CO2) emissions. The resulting aromatic precursors are source chemicals for insulation materials, plastics, textiles, and jet fuel, among other valuable products.

One day, when humans go to Mars, they might find that, occasionally, the red planet has green skies. In late December 2014, NASA's MAVEN spacecraft detected evidence of widespread auroras in Mars' northern hemisphere. The "Christmas Lights," as researchers called them, circled the globe and descended so close to the Martian equator that, if the lights had occurred on Earth, they would have been over places like Florida and Texas.

Solar power has long been touted as the solution to Africa's lack of power generation capacity, and South Africa's almost year-round sunshine makes it an ideal remedy to lack of electrification in rural and under-serviced areas. According to the Department of Energy, most areas in South Africa average more than 2 500 hours of sunshine per year, and average solar-radiation levels range between 4.5 and 6.5kWh/m2 in one day.
