Lithium-sulphur batteries can store up to five times more energy than traditional lithium-ion batteries, but their lifespan is quite limited. Now a team of Australian researchers claim to have found a sweet solution to make them a truly longer-lasting, lighter and more sustainable alternative for all types of transport.

From breaking the sound barrier to making the futuristic dream of flying cars a reality and optimising energy consumption by reviving the tradition of making houses out of straw. We analyse the technological innovations that have captured the attention of our readers over the last year.

A few years ago Google launched eyewear capable of recording what was around them. Although this futuristic technology generated a lot of buzz, the project ultimately failed. But almost a decade later, technology companies have not given up. Here we explore how Facebook, Huawei and Xiaomi hope to reach the mass market with their smart glasses.

While under normal conditions a container ship travelling from Asia to the USA takes two weeks, it now takes 70 days from the time a product leaves the factory to when it reaches store shelves. The crisis in the global supply chain threatens to cause delays in some Christmas orders.
