Luis Hernan was always curious about how wireless technologies like radio are transmitted through the air. So after finishing up his studies in architecture, computer science, and design, Hernan decided to research these invisible signals through a PhD at Newcastle University. Hernan set up a system that turned the wireless signals around him into colourful, ghostlike images using long-exposure photography, allowing people to see the strength of the signals around them.

Doctor Boaz Zissu of the Bar Ilan University shows the inscription on a 2,000-year-old ossuary at the Rockefeller Museum on June 30, 2011 in Jerusalem, Israel. The Israel Antiquities Authority have confirmed the credibility of the ancient ossuary, otherwise known as a stone chest in which to store bones, as bearing the name of a relative of the high priest Caiaphas from the New Testament. Laboratory tests have come back saying that the inscription with the name of “Miriam daughter of Yeshua son of Caiaphas, priest of Maaziah from Beth Imri” is both “genuine and ancient”.
