An Invisible Man with perfect vision sounds like a superhero from a comic, but may be close to reality thanks to scientists at the University of St Andrews. A team of physicists are one step closer to creating a Harry Potter-style invisibility cloak, with a new form of material that could also be attached to contact lenses to provide ‘perfect’ eyesight.
German scientists announced on Monday they believe they have discovered sunken islands in the Caribbean Ocean following a deep sea expedition in April. During their six weeks in the waters north of Venezuela and west of the Antilles, the experts from the University of Greifswald analysed rock samples from depths of more than 1,000 metres.
Stanford scientists are harnessing nanotechnology to quickly produce ultra-lightweight, bendable batteries and supercapacitors in the form of everyday paper. Simply coating a sheet of paper with ink made of single-walled carbon nanotube (CNT) and silver nanowire films makes a highly conductive storage device, said Yi Cui, assistant professor of materials science and engineering at Stanford University.
