The smartphone tool is demonstrated on visiting associate professor Nemuel Daniel Pah Seamus Daniel, RMIT UniversityEarly medical intervention is crucial for stroke victims, and a new smartphone tool aims to facilitate this by enabling first responders to quickly assess whether a patient has suffered a stroke.Improving Stroke Treatment with Early Detection ToolsIn such instances, patients...
DNA is a much denser data storage medium than anything humans can design, but it is fragile. Scientists have now mimicked nature by creating artificial amber to protect DNA for long-term data storage.A single gram of DNA can hold up to 215 petabytes (215 million GB) of data, making it possible to store the...
