Science Report with and Shaun Hendy. A memory transplant, a cure for the common cold and how the fall of the Roman Empire is etched in Arctic Ice. Also, NASA has released a video of their ground breaking new micro helicopter where science bands together with technology. Astronomer Dr Grant Christie joins Graeme Hill to talk cosmic mystery, Scholzs star and how it shook up our solar system, and a proposed Martian helicopter. The NASA Martian helicopter will hugely increase the range of surveys, Dr Christie says. Weighing in at about 1.8 kilos and the size of a cricket ball, the micro helicopter is set to explore the Red Planet. Counter-rotating blades spin at 3000rpm in order to cut into Mars atmosphere- averaged at 1% of that on earth. A massive flare erupts from our nearest stellar neighbour. An observatory from Chile has detected the flare from Proxima Centauri - one of the closest stars to our solar system. Also, the Hubble space telescope has been looking at a distant galaxy to uncover a new cosmic mystery and its connection to early star formation. Dr Christie also speaks of how Scholzs star shook up our prehistoric solar system. Listen to the full interview with Dr Grant Christie above.
