Illustration: Harry Campbell Wireless isn’t actually ubiquitous. We’ve all seen the effects: Calls are dropped and Web pages sometimes take forever to load. One of the most fundamental reasons why such holes in our coverage occur is that wireless networks today are overwhelmingly configured as star networks. This means there’s a centrally located piece of […]

The dawn of the robot revolution is already here, and it is not the dystopian nightmare we imagined. Instead, it comes in the form of social robots: Autonomous robots in homes and schools, offices and public spaces, able to interact with humans and other robots in a socially acceptable, human-perceptible way to resolve tasks related to core human […]
Demand for battery-making metals is projected to soar as more of the world’s cars, buses, and ships run on electricity. The coming mining boom is raising concerns of environmental damage and labor abuses—and it’s driving a search for more sustainable ways of making batteries and cutting-edge electronics. Artificial intelligence could help improve the way battery […]
This diagram shows the artificial tendon material versus real tendons at different scales. Image: Mutian Hua, Shuwang Wu, and Ximin He/UCLA. Materials scientists at the University of California, Los Angeles (UCLA) and their colleagues have developed a new method for making synthetic biomaterials that mimic the internal structure, stretchiness, strength and durability of tendons and […]
The 4D hydrogel-based material changes shape in response to water. In the image, the grey side of the material absorbs water faster than the blue side, causing it to bend into a 'C' shape. Image: Yu Bin Lee. New hydrogel-based materials that can change shape in response to physiological stimuli, such as water, could provide […]

Designer Rolls-Royce has successfully completed the taxiing phase of the testing at Gloucester Airport in western England. Rob Watson, Director at Rolls-Royce Electrical said: “Electrification of flight is an important part of our sustainability strategy as we aim for net zero […]
Creating a virtual experience that’s as close to real life as possible is one of virtual reality’s (VR’s) ultimate goals, as companies and researchers find ways to accurately mimic a person’s facial expressions and body gestures. But if the lighting and shadows on faces—notoriously tricky to simulate with accuracy—are all wrong, expressions and gestures don’t […]
