Millions of children in England are using messaging platforms that they are not old enough to be accessing and the introduction of end-to-end encryption (E2EE) could increase their risk of exploitation, the Children’s Commissioner for England has warned in a report. The Commissioner’s report follows announcements by Facebook – and indications by other social platforms, such as Snap – … Read more
High-powered computers are back, but how do we deal with their thirst for energy? By the end of the 1980s, big iron was showing more than a touch of rust. Monster machines like the Cray-2 ruled supercomputing. It was an age when, supposedly, no-one got fired for buying IBM: Big Blue dominated enterprise computing with … Read more
An MIT study has demonstrated that deterioration in the performance of InGaAs (indium gallium arsenide) transistors at small scales is not an intrinsic property of the material. For computing power to continue to improve into the future, supporting more computationally expensive processes, engineers will need to develop ever-smaller and more densely packed transistors. For decades, … Read more
CEO of EngineeringUK, Dr Hilary Leevers outlines the work being done by her organisation to inspire and engage with ‘tomorrow’s engineers’ in the 11-to-14-year-old age bracket and beyond. “All young people should be enabled to understand what engineering is and be motivated to engage with it as a career pathway,” says Hilary Leevers. It’s a … Read more
