The 3-D sky-mapping project called the Dark Energy Spectroscopic Instrument or DESI will measure the light of millions of galaxies. *Revolutionary Wifi invention selected for World in 100 Objects Exhibition A revolutionary 1992 Australian invention that led to Wi-Fi has been chosen by the National Museum of Australia to be part of the A History of the World in 100 Objects exhibition, opening in Canberra next month. The exhibition will showcase items from around the globe to explore human history, sourcing the oldest objects from the British Museum's collection and incorporating those from the present day. *The possibility of creating a new type of photon New research suggests that it is possible to create a new form of light by binding a photon to a single electron and combining the properties of both. The combined photon electron would have properties that could lead to circuits that work with packages of photons instead of electrons.
