Researchers Find Emissions-Free Way to Make Cement

Researchers at MIT have developed a way (though admittedly experimental) to produce emissions-free cement—that means the manufacturing process “releases no carbon dioxide into the atmosphere.” This is a hugely significant breakthrough, as cement manufacturing (for the intention of making concrete) is responsible for almost 10% of global emissions. The process includes an electrochemical method, which would replace the current one, which is dependent on fossil-fuels. …

MIT’s New Color-Changing Ink, PhotoChromeleon

From MIT’s Computer Science and Artificial Intelligence Laboratory comes a product that could calm the nerves of fickle consumers. PhotoChromeleon is a high-tech ink that changes color through “reprogramming.” This means exposing the ink to UV light to activate or deactivate some of its components, which include “a scientific mix of cyan, magenta, and yellow photochromic dyes,” according to Fast Company. The sprayable ink can …

AlterEgo Listens to the Voices in Your Head

24-year-old inventor Arnav Kapur’s wearable device AlterEgo, which we previewed during this year’s Ted Fellows announcement, aims to assist people with communication problems by reading the voices in their head. According to Smithsonian Magazine, the technology does so through “a system of sensors that detects the minuscule neuromuscular signals sent by the brain to the vocal cords and muscles of the throat and tongue.” These …
