Many insects and spiders get their uncanny ability to scurry up walls and walk upside down on ceilings with the help of specialized sticky footpads that allow them to adhere to surfaces in places where no human would dare to go. Engineers have used the principle behind some of these footpads, called electrostatic adhesion, to create an insect-scale robot that can swerve and pivot with the agility of a cheetah, giving it the ability to traverse complex terrain and quickly avoid unexpected obstacles.

Batteries are potentially a game-changing technology as we decarbonize our economy, and their benefits are even greater when shared across communities, a study has found. The study says reducing costs are seeing rapid deployment of batteries for household use, mainly for storing solar and wind power for later use, but they could have a variety of uses in a future electricity grid.

An elegant new algorithm developed by researchers can significantly reduce the resource consumption of the world’s computer servers. Computer servers are as taxing on the climate as global air traffic combined. Therefore, it makes the green transition in IT an urgent matter. The researchers expect major IT companies to deploy the algorithm immediately.


6. A New Look at Colour Displays

Researchers have developed a new and simple method to create structural colours for use with reflective colour displays. The new method may enable manufacturing of thin and lightweight displays with high energy-efficiency for a broad range of applications. The method can produce all colours in the visible spectrum. Furthermore, the colours can be subsequently adjusted using electrochemical variation of the redox state of the polymer.
