Liquid crystals create easy-to-read, color-changing sensors
Chameleons are famous for their color-changing abilities. Depending on their body temperature or mood, their nervous system directs skin tissue that contains nanocrystals to expand or contract, changing how the nanocrystals reflect…
Engineers design a reusable, silicone rubber face mask
Researchers at MIT and Brigham and Women’s Hospital have designed a new face mask that they believe could stop viral particles as effectively as N95 masks. Unlike N95 masks, the new masks…
Reducing noise transmitted through an open window
Shutting the window is usually the last resort in mitigating environmental noise, at the expense of natural ventilation. To prevent the noise without losing natural ventilation, a new device that can reduce…
Purifying water with the help of wood, bacteria and the sun
According to the United Nations, about one-fifth of the world’s population lives in areas where water is scarce. Therefore, technologies to produce clean water from undrinkable sources, such as seawater, river or…
