Fluorescence filters are part of a process that allows computers to be built using sugar, and not silicon. Scientists at the Friedrich Schiller University Jena in Germany have demonstrated how simple logic gates – the building blocks of computing – can be built using sugar. The key to this is introducing sugar solution to a […]
Optical filters near infrared could be used to create cancer-detecting goggles, allowing surgeons to spot tumours in real time, according to research from the US. A study in the Optical Society’s academic journal Optics Letters outlines the process, which combines optical filters near infrared for the detection of marked cancer cells with ordinary visible light […]
Ozone detection will be essential in the years ahead, as climate change means pollution levels of the gas are likely to rise substantially. The National Center for Atmospheric Research in Boulder, Colorado, has published research showing that summertime ozone levels in the US are likely to increase by as much as 70% by 2050. It’s […]
