Such themes are explored in Why We Post - a global social media research project carried out by a team of UCL anthropologists. Click talks to two of the researchers: Jolynna Sinanan worked Trinidad and Tom McDonald worked in China. 5D Data Storage: Ultrafast Laser Writing on Glass Scientists have made a major step forward in the development of digital data storage that is capable of surviving for billions of years. Using nanostructured glass, scientists from the University of Southampton’s Optoelectronics Research Centre (ORC) have developed the recording and retrieval processes of five dimensional (5D) digital data by femtosecond laser writing. Click has a clip of lead researcher, Professor Peter Kazansky and interview with PHD student Aabid Patel. 3D Mapping in Lesotho Although more than 90% of people in Lesotho are literate, a large number of people have difficulty reading and understanding maps. This is important when it comes to the dissemination of information about town/village planning and mapping danger zones. Click talks to Seitebatso Mohlahatsa, the planner who has a project to use 3D printers to map villages.
